Plan and Build Computer Network
ICAITS021C Connect internal hardware components
ICAITS030B Install software to networked computers
ICAITS116B Undertake capacity planning
Question 1: What is meant by capacity planning in information technology?
Answer Suggestion:
Capacity Planning is the activity relating to the management of the information communication infrastructure to ensure that the output of the facility is maximized and the input is minimized.
The activity involves the use of tools to measure inputs and outputs that may be competing. Constraints come in the form of labour, material availability, equipment utilization and limited space. Planning, the use of mathematical models and flexibility in resource utilization is needed
Capacity planning in information communication technology systems is needed when:
Starting a new system, or a service organization
Extending the operations of an existing business system.
Considering additions/modifications to the system
Introducing new techniques, equipment and materials
Question 2: What are some of the factors that capacity planning needs to consider?
Answer Suggestion:
Bottlenecks that will determine the capacity for any particular stage of the process.
Peak demand rate
Communication Bandwidth
Load balance within the system
Existing Hardware and scalability
Cost
Technology changes in hardware and software
Question 3: Briefly describe the following terms
a. Design Capacity
Answer Suggestion:
Target output level
Note: It could be reached or exceeded in practice.
It is the agreed % between vendor contractor and customer of the system
b. Effective Capacity
Answer Suggestion:
It is the actual capacity to reflect current conditions.
Note: could be less than or more than design capacity.
Required because of; limited resources, increased equipment breakdowns when run at higher capacity for long periods and the impact of the environment.
c. Utilization
Answer Suggestion:
Measures use of resources i.e actual running time.
Measure as % of effective capacity.
Note: measurement is often different between organizations and systems.
d. Yield
Answer Suggestion:
Measures output of product in % against equivalent, potential or maximum products or systems’ input.
Question 4: What are the stages in capacity planning?
Answer Suggestion
1. Analyse existing system capacity
2. Determine future capacity requirements
3. Plan for capacity enhancement
4. Install capacity enhancements
Question 5: Describe some of the commerce site metrics in capacity planning for a business that is moving into e-commerce.
Answer Suggestion
a. Hits: Results of multiple hits from the browser to the Web server
A hit is any request from the browser to the Web server this includes requests for dynamic content, images, or streamed video
b. Average hits per page: The average number of Web server hits per page.
The suggested configurations used stores with 1 hit per page. The test tool did not load any images, nor did it use frames. The test tool only made one HTTP request per page.
c. Commerce/non-commerce page ratio
Most pages are generated by issuing a database query and rendering the results by using JSP (Java Server Page) templates.
Typical stores also contain some static content, such as HTML page requests. The suggested configurations did not contain any requests for purely static pages. Static pages are served at roughly the same rate as static images.
Requests for static pages can be ignored in capacity planning, if the ratio of dynamic requests to static requests is fairly high. A site which serves two dynamic pages for every static page can be sized without regard for the static pages.
This is because dynamic pages require substantially more resources to serve.
d. Database size
The database size affects performance of the system. Sites that include many shoppers, merchants, or catalogue items usually cannot serve requests as quickly as those that do not.
Various factors will affect the throughput of the system, including database tuning, hardware capacity, and physical topology.
e. Megabytes of data that are served per unit of time
It is important to plan your site to have sufficient resources for serving expected network throughput. This includes sizing all firewall, routing, and other network components to be able to handle the peak workload expected of your site. The suggested configurations can be measured using a full duplex 100 Mbps Ethernet between the load generator and Web server.
A 100 Mbps switch can be used between the Web server and database server.
It must be noted that added equipment results in the Internet communication being significantly slower.
If the site is running web casts or real time audio, this will demand bandwidth. This has to be taken into account in the overall capacity planning solution.
f. Performance Test Scripts
The commands executed affect system workload.
Te set up and the commands run as part of performance tests can be like the following.
Components:
A basic store that contains a set of use cases commonly used in shopping model:
– New shopper registration
– Registered shopper logon
– Browse categories, products, and items
– Add item to shopping cart
– View shopping cart with tax and shipping details
– Modify quantity of items in the shopping cart
– Delete items from the shopping cart
– Checkout by entering billing and shipping information
A script to generate the following:
– Up to 5 000 categories
– Up to 50 000 items
– Up to 50 000 registered customers
– Up to 50 000 orders
A script to simulate various shopper scenarios
– Browse
– Add
– Prepare
– Buy
A script to define the regular shopping mix
The regular shopping mix depends on two variables:
1. Customer type
New registered customer
Existing registeGuest shopper
2. Shopping flow
Browse
Visit the home page
Logon using registered customer id (existing registered customer only) or register as a new customer (new registered customer only
Select “Multiple Category Display” then “Multiple Product Display”
Browse and Add
Browse, and then randomly add one, two, or three items to the shopping cart.
Browse and Prepare
Browse and add, then enter address book information (guest shopper only) or specify which address to use (new registered customer or existing registered customer).
Browse and Buy
Browse and prepare, then display order information. Enter a credit card number with expiry date, finally submit the order.

Capacity planning information
Capacity planning is the key to a well-oiled, smooth-running data center, helping IT organizations to:
*Accurately and efficiently provision new applications
*Reduce, delay and sometimes completely avoid costs
*Justify upgrades with objective analyses
*Optimally configure systems to accommodate forecasted changes in business
*Migrate systems to take advantage of new technology
*Consolidate servers to simplify management and gain economies of scale
*Mitigate service delivery risk by playing out potential scenarios in advance, and then preparing for them
Capacity Planning Techniques
A variety of capacity planning techniques are available, each useful in its own right. TeamQuest provides tools for each of these techniques:
Trending
Trending uses simple extrapolation of resource utilization over time. The advantage of this technique is that it does not require sophisticated tools. A spreadsheet will do, but it can be difficult to take into account non-linear behavior buried deep within a multi-tiered system.
Linear TrendAnalysis
Linear trend analysis looks at historical data and projects a linear trend line into the future, applying upper and lower confidence intervals as well as a threshold at which resources will become inadequate. This capacity planning method is a quick sanity check and identifies over-utilized resources, but it does not allow for experimentation with different configurations.
Short TermAnalysis
Short term analysis identifies potential problems early by generating exception events (alarms) based on historical averages (rather than a fixed threshold) tied to a particular point in a periodic time interval. For example, if a particular resource averages 60% busy on Tuesdays and 50% busy on Thursdays, an exception event will only be generated when utilization crosses those thresholds on the respective days.
SimulationModeling
Simulation, a much more sophisticated capacity planning technique than trending, actually simulates the queuing events that occur during execution. The downside of simulation modeling is that it can be very time-consuming to build and run the models.
AnalyticModeling
Analytic modeling uses mathematics to calculate how a queuing network will perform. To use analytic modeling, a baseline set of measurements is taken on a system and a model is then built based on a description of the system. Results from the model are compared with the baseline, and when they match, the model is considered calibrated. From there, hypothetical changes can be made to system configuration or business workloads, and the model will predict how the changes will affect performance. Done properly, analytic modeling is a fast and accurate capacity planning technique.
Analytic Modeling and Load Testing
Especially when rolling out new applications, it can be useful to use a load-testing tool in conjunction with an analytic modeling tool.
A load-testing tool can be used to simulate transactions coming from end users, or applications can be benchmarked on test systems to be certain they can support required service levels. However, time and cost considerations often make it prohibitive to conduct such tests on the actual hardware using production-level workloads. Full-sized machines and software are too costly to dedicate for testing purposes, and finding the optimal configuration through empirical testing can take a long time.
Instead, smaller but representative loads can be applied to a scaled-down set of test servers while performance analysis software takes a baseline reading of performance. Analytic modeling can then be used to rapidly predict how various configurations will perform under a production-level workload, all without the need to purchase the actual configurations under consideration. Analytic modeling is a cost-effective, fast and accurate alternative to brute-force testing.

Wizard
A facility included in many commercial software applications which allows complex tasks to be automated for inexperienced users or to save time for “experts”
WYSIWYG
What you see is what you get. The printout is the same as the screen display
Templates
Templates and a consistent document format ensure that commercial documentation maintains a coherent look and “feel” across an organization. The use of consistent information (e.g. organization details, phone numbers etc) ensures accuracy across documents.
Templates also ensure that objects that are applied to a number of documents (eg an organization logo) can be stored in the one file location and dynamically linked within an organization’s network. This has many advantages. All documents have the same look and feel and if information needs to be updated, such as a new fax number, logo or email address, the new information needs to be updated only once.
Microsoft Office has several examples of templates. In MS Word there are templates for minutes, memos, faxes and resumes and other publications. These documents have a .dot extension. In MS Excel there are templates for invoices and finance related templates. These have a .xlt extension. Familiarize yourself with these standard templates.
Exercise 1
Questions 1 to 5 are short answer questions.
1. A template is available for most applications when you store them in a Templates Directory. What is the location of this directory on the computer you are using now?
To find where your template files are stored, use the find facility to look for *.dot files.
2. Describe some of the common tasks that are performed when creating a new template.
Your answer could include: -
a. setting up headers and footers
b. adding a logo
c. placing commercial information to create a letterhead
d. setting the default font and styles
e. setting page margins.
3. Touch typing is a useful data entry skill. What is touch typing?
Touch-typing is the skill of knowing where all of the keys are on a standard keyboard layout and using specific finger movements to most efficiently activate the appropriate key. It relies on having a standardised key layout and the concept of “home keys”.
4. What course of action should you take to prevent RSI?
RSI or Repetitive Strain Injury is caused by long sessions of the same movement as in the action of touch-typing. Regular rest breaks and ensuring that the fingers are moved through their full range of movement is a good method of avoiding this type of injury.
5. What does “confidential” mean when used in connection with commercial documentation?
“Confidential” refers to the fact that some documents are not intended for general distribution and may be protected to ensure that only the specified recipients are able to view the contents when online or via emails. In the past, hard copy documents could be kept locked away from public access. With the advent of networks and electronic storage the concept of confidentiality is more difficult to enforce.
6. Choose from the options below.
WYSIWYG means: -
a. what you see is what you get
b. the file is displayed on the screen as it is to be printed
c. the web layout of a printed page.
What you see is what you get. The acronym is a leftover from the first computer programs when they often showed only the code and the hard copy would display the actual code actions. This is similar to modern HTML where hello would display in a web browser as hello.
Answer True or False to the following questions.
7. A data entry person who uses a template to create a document should then save the file to the document template directory.
TRUE / FALSE
FALSE. If the files have been created from a template that is opened from the templates directory then the user is given the default option of saving the file as a document that they can name. If the template has been saved in other directories then they may have to use the Save As option.
8. A scanner can only digitise photographic images.
TRUE / FALSE
FALSE. Scanners are merely a device designed to digitise black and white areas or coloured areas of a scanned document. Graphics programs and Optical Character Recognition programs allow the digitised information to be manipulated correctly.
9. Each page of a printout is a separate file.
TRUE / FALSE
FALSE. This is a common mistake of new users of word processing software, especially where different topics are covered in the one document. Word processors are able to delineate page spaces effectively to create multi page documents.
10. There is an automatic facility to include page numbers in a document
TRUE / FALSETop of Form
TRUE. There are a number of scripted modules that allow text that is commonly used in documents to be included in the files using the appropriate metadata to update automatically (eg date, time printed page number).
Exercise 2
Multiple choice
1. Desk Top Publishing is:
a. a device used to create high quality printouts by ensuring that the paper size is accurately accounted for
b. a software application used to combine graphics and text objects to produce high quality publications
c. an organisation listing where the output to be printed on large printing presses using lead typeface
d. a type of commercial enterprise where they specialise in coffee table books of a high quality.
2. The Print Preview:
a. will appear different if an alternative printer is selected for the print job
b. allows a developer to ascertain if a hard copy will print correctly
c. allows a developer to ensure that all words are spelt correctly
d. ensures that the document will be readable when printed on orange paper.
3. A form is:
a. only available as a printed document
b. only available when using a database application
c. a document used to gather data from an audience
d. a document designed to lead a user in entering data to ensure consistency and accuracy of information.
4. Which of the following is a health hazard?
a. laser printer toner powder
b. ink jet printer ink
c. paper dust
d. All of the above.
5. Expiry date is:
a. the date by which a document needs to be removed from circulation
b. the date by which a project is to be completed
c. what happens when the manager finds out you didn’t put the ad in the Yellow Pages
d. the date by which a document is no longer accurate or viable.
Word Processing
To ensure that documents belonging to an organisation are consistent and include correct, relevant information (logo, contact details and text styles) we create a letterhead and style sheet. This ensures that the information will be placed correctly and appropriately in the document.
To create text documents on a computer we use a word processor rather than a text editor. A text editor stores the ASCII characters in a data table of character position and ASCII value. A word processor has a similar basic function, however each character has large amounts of metadata held in the array as well.
Touch typing is a good skill to possess – use a typing tutor program to practise such as TypeQuick or Typing Tutor. Touch-typing allows for the quick entry of original text data. If hard copy exists then scanning and OCR is often an appropriate method. Speech to text recognition software, such as Dragon NaturallySpeaking or Point and Speak Voice Recognition, can speed up the process of text entry for slow typists.
As most documents created in a word processor are meant to be viewed as hard copy (printed on paper) the basic word processing applications tend to be WYSIWYG. Use the Print Layout option on the View menu to see how the document will looked in printed format as you are creating it. This is important if you are drawing objects such as a flowchart.
Tip If you need to change the settings of the various document sections use the File - Page Set-up Menu.
Document Templates
To allow for quick development of complex documents and to keep uniformity within the commercial environment, templates are often created. You will need to create your own template to use as a basis for the rest of the task.
Exercise 3
1. What are some of the ways Help files aid new users unfamiliar with a software procedure?
Your answer could include the following points:
1. the ability to find out how to perform a specific task
2. to research how a task could be managed more efficiently
3. to solve a specific problem encountered while using the software.
2. Compare and contrast the two types of Help files available, namely printed booklets and online resources.
Your answer could include the following points:
1. Both types allow a user to find out how to solve problems with software applications or hardware devices.
2. Both are able to be referenced by using an index and a contents page.
3. Both are organised into passages that deal with related problems.
4. Online files are able to be searched for keywords efficiently.
5. Online resources are able to have wizards and macros attached to allow a user to see a procedure in a step by step fashion.
6. Paper based resources are able to be accessed even when the computer has frozen.
7. Paper based resources are able to be read anywhere, e.g. on public transport whereas online resources require access to computers and a network.
3. How would the language used differ for the different audiences you may have to deal with?
An experienced user will generally be looking for very specific information and will be able to comprehend technical terminology. New or inexperienced users will require simpler sets of instructions using less technical language. They would probably benefit from the more time consuming development of wizards and “how to” animations.
4. Define the term hyperlink.
A word, section of text, image or information object which has a connection to another.
5. What is a “target” when referring to links?
A “target” when referring to links is the destination of the link
6. Define the term “bookmark” in reference to linking.
A bookmark is an item or location in a document that you identify and name for future reference.
7. Why are bookmarks often used in templates and documents?
Book marks are used to automate data entry and to find information in documents. They are also used in table of contents and indexes.
8. Briefly describe the process of creating a bookmark in Microsoft Word.
Select the item you want to bookmark. On the Insert menu select Bookmark. Give your bookmark a name. Click Add.
9. Describe the process of saving a word processed document as a web document.
From the File menu select the Save as Web page option and give your document a name. The file is saved as .html.
10. Why do organisations often save their documents in both word processed format and web format?
To be able to publish documents on a network and on a intranet/internet.
Creating a form
Automated forms are widely used for data entry. The forms are designed so that the cursor moves to the next data entry point automatically. This saves time and there is less chance of entering incorrect data.
When a survey is being conducted the data is usually saved in a database. It is extremely important that the client fills in the details in the appropriate manner with complete accuracy.
Automated forms can be created to allow people to enter data into an online form and then: -
Spreadsheet Template
Spreadsheets are used to perform calculations. Often a data entry person will be required to enter figures that are used to produce mathematically complex results. In addition to this when wage calculations are considered there are privacy, security and accuracy issues to be dealt with. For these reasons it is often necessary to create a template for users to enter data into specific cells and then see only the results they are entitled to view.
Create a spreadsheet template
You will be required to create a spreadsheet that will calculate the wages of the employees of a section of a small organisation. The employees are only allowed to enter in the number of hours they have worked that week. The Section Manager is allowed to enter the base pay rate for the employees’ award, as well as the seniority pay scale. The Manager is also able to enter any overtime hours the employees work. You will need to password protect the template
An example of a possible spreadsheet is given for you to use as a basis for developing your own.

Case study 1
You are an employee of Bits & PCs Computer Services Company and one of your tasks is to attend the helpdesk enquiries for two hours every day. There are three of you doing this during a normal day, but on this particular day one of your workmates is off sick and you are asked to do his two hours as well as your own.
Along with this you also have some urgent tasks that you feel you really need to try and do in between enquiries. The day begins quite well and you seem to be making progress, however, you start to get very busy on the helpdesk and you end up working through lunch.
Later in the afternoon, you decide it is time to have a quick break. In your rush, you trip over the electrical leads hanging down beside the desk and land on an open PC case, cutting your hand and badly bruising both knees as you hit the floor!
You are not seriously hurt, but shaken and your hand will need some attention to stop the bleeding.
1. Fill out the information on the Injury/Investigation Report below, using all your own details and the relevant information from the above case study.

OH&S REPORT FOR WORKSTATION
Eriks European Motor Mechanic Workshop
Background
This workshop has the following dimension: 900 M2 (30m x 30m), ceiling height 5 metres, 6 windows in the back, the exit is located on the left side of the building, in the front we have 2 roller doors. Inside of the roller doors there is a reception desk. This is located on the right side of the building on the back. The reception area is 8m x 8m (64 M2). The FIRST AID KIT is located in the reception area. The reception area is secured. The existing reception area has already one workshop. Right next to reception workstation there is enough footprint for the new workstation that connects to the RTA mainframe server.
As this reception area is isolated there is the barrier to isolate sound. This reception area has reverse cycle air-conditioning with climate control (humidity and temperature). There are sprinkles and smoke detector. In the workshop and reception area are separate fire extinguishers. They are CO2 based. CO2 fire extinguishers are good for electrical and oil based/hydrocarbon fires. There is fire blanket in the workshop. In workshop there is sufficient ventilation extract fumes and carbon monoxide. There is one window in the reception area. This is located on the right side of the area. As the result this does not affect excessive amount of glare from the screen. Inside reception area there are 6 sets of power points. Currently only two sets of power points are in constant use. Therefore, there are sufficient power points for the work station. Lighting requirements for the new workstation is an issue. There is insufficient artificial lighting in the propose area. For the current staff there are two trained mechanics and two apprentice mechanics. In addition, there is one clerk that does the administration work. The two mechanics as part of their training and experience have already the OHS skills and knowledge for the job. These two mechanics have the responsibility for training of the clerk and two apprentice mechanics on OHS WORKCOVER requirements.
The floor plan is given in figure 1
Recommendation:
Install the RTA computer in the office facing the door. Install another light above the computer. This would comply with the requirements of the WORKCOVER guidelines for environmental factors. For ergonomic requirements an additional ergonomic chair is purchased. The computer system is installed based on the WORKCOVER guide lines for the following:
1. The angle of the screen to the eye is max 30 degrees to horizontal. This is to protect the neck.
2. The key board is positioned to reduce stress on the risk.
3. The back rest is adjusted to ensure the back is vertical when seated.

Recommendation
Strains and Sprains
Potential Hazard
Teens often work serving food in restaurants. Serving food and bussing tables, especially while assuming awkward postures, may lead to back, neck, and shoulder strains and sprains. Specific potential hazards include:
• Balancing or lifting too many plates or glasses while serving or clearing tables.
• Balancing or lifting heavy trays above shoulder height.
• Lifting large, overfilled containers of dirty dishes.
• Repetitive reaching across tables to serve customers or to clear tables.
Moving and lifting tables and chairs to accommodate customers.
Avoid over-reaching across tables or booths.
Possible Solutions
Teen Safety Solutions
Employers have the primary responsibility for protecting the safety and health of their workers. Employees are responsible for following the safe work practices of their employers.
• Avoid awkward postures if you must carry trays, plates, or beverages. Serving with awkward postures such as unsupported elbow and finger postures can increase your risk for injury.
Limit the number of plates or items you will carry, realizing that carrying more than a couple items puts excessive strain on your arms and back and may lead to injury.
Unsupported elbow and finger postures
Use both hands to carry items such as coffee pots or water jugs and carry them with your elbows close into your body.
• Move the glass or cup to you, when pouring, rather than overreaching with a heavy coffee pot or water jug to fill a glass.
• Carry plates with your elbows close into your body to lessen the strain on your arms and back. Avoid bending at the wrist or extending upward at the fingers. Your shoulder, arms, and hands should be in a neutral position rather than bent at the wrist or extended upward at the fingers.
• Balance the tray on both your arm and hand.
• Alternate carrying tasks from hand to hand.
• Balance the load evenly, placing heavier items in the center of the tray.
• Make sure trays are serviceable and clean and dry and without defect before using.
• Stand by the person you are serving if possible, rather than reaching across tables and over people. In booths, pass the plates along, requesting that the people sitting closest to the edge of the booth assist you in passing the plates.
Get help to move tables and chairs, rather than lifting alone
Employer Solutions
Employers have the primary responsibility for protecting the safety and health of their workers. Employees are responsible for following the safe work practices of their employers.
• If space permits, provide serving carts to carry food, rather than requiring workers to carry heavy trays overhead.
• If space permits, provide workers with a server's station close to the serving area. This will decrease the distance that items need to be carried.
Manual Handling Regulations 1992
The act lays down minimum health and safety requirements for the manual handling of loads and requires a risk assessment of all manual handling to be made by a competent person. Employers must reduce and avoid the need for manual handling, and, where it is unavoidable, take measures to minimise risk, particularly from back injuries. The act sets out the weights and types of loads that can be handled. Employees have an obligation to comply with the regulations, and to use the right technique or equipment for lifting and handling jobs.
Provision and Use of Work Equipment Regulations 1992
Under these regulations employers must:
• provide suitable equipment for every task;
• ensure that equipment is in good condition and only used for suitable operations;
• provide training, instruction and information on all equipment;
• ensure equipment conforms with EC product safety directives.
The act specifically extends to maintenance operations and provision of warnings and markings on site.
Noise at Work Regulations 1988
The act sets out specific limits for noise levels, and the action required to reduce noise risk at each level.
Personal Protective Equipment Regulations 1992
The act describes equipment for protecting against risk to health and safety for all workers. Personal protective equipment (PPE) is the last resort for personal protection, and it is only used when all other methods to make a task safe have been applied. Employers must ensure the suitability of PPE provided, maintain good PPE provision, provide storage for PPE when not in use, and give training and information on how to use PPE correctly.
All PPE must conform to current EU directives and should bear the ‘CE’ mark.
Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 1995
The act requires that all accidents resulting in more than 3 days’ absence from work, or where the person cannot return to their normal tasks, or involving more than 24 hours in hospital, are reported. A responsible person must make a report. The act defines major injuries, dangerous occurrences and recordable diseases that must be notified. Specific reporting forms must be used and are available from HSE field offices.

Case Study
Email Policy
The following links to the Australasian Legal Information Institute have some interesting information regarding the use of e-mail in the workplace. This is an area that has hit the media and the courtrooms recently due to employee claims of unfair dismissal and invasion of privacy.
The section of the website called, Privacy Law and Policy Reporter, publishes articles relating to privacy and computing. Read the article titled E-mail Privacy
The article recommends that organisations publish their email policy so that employees are aware of the correct use of email and the consequences of any breach of the email policy.
Task 1
Locate your work placement or another organisation's email policy. Briefly outline the acceptable use of email for your organisation. Are the consequences of breaching this policy documented ? If so what are the consequences?
Employees and emails
Look at this web site Read the section Legal Setting of employment. This section discusses the topic of surveillance. Computer software can now monitor every keystroke that an employee makes for as little as $99. This section also refers to "cyber slacking", which is the use of email and the internet during work time posing a threat to productivity.
A well publicised court case involving the use of email during work time was between Ansett and one of its employees, Ms Gencarelli. Ms Gencarelli was a union delegate and she distributed information via email which was critical of Ansett's role in the negotiations with her union. She was dismissed for "unauthorised business use" of email. The case went to court and the judge ruled that the use of email was "authorised business use" and Ms Gencarelli was reinstated.
You can read the details of this case here under the heading Employees and emails
Task 2
Computerisation has increased productivity, however, it also has the capacity to decrease productivity. How?
What strategies are some companies implementing to monitor employees use of computers during work time ? Is this ethical?
Do you agree with the judge's ruling in the case between Ms Gencarelli and Ansett ? Why or why not?
