1. Element 3 Identify information technology equipment

2. LEARNING OUTCOMES
1. Clearly identify the information technology equipment/software and operating system supported by the organization.
2. Accurately identify equipment, location and service requirements according to organizational requirements.

3. IDENTIFY INFORMATION TECHNOLOGY EQUIPMENT/SOFTWARE AND OPERATING SYSTEM
As an employee of an IT organization it is important to be aware of the type of equipment and software that are in use as these will be your ‘tools of the trade’.
Computer - a programmable electronic machine that:
• takes in data and instructions (input)
• works with the data (processing)
• puts out information (output)

4. Equipment IT equipment may include but is not limited to:
Personal computer
Network systems
Attached Peripherals
Personal computer - A small, relatively inexpensive computer designed for an individual user. Businesses use personal computers for word processing, accounting, desktop publishing and for running spreadsheets and database management applications.

5. Network systems There are many types of computer networks, including:
Local-area networks (LANs) - The computers are geographically close together (that is, in the same building)
Wide-area networks (WANs) - The computers are relatively far apart and are connected by telephone lines or radio waves.
Campus-area networks (CANs) - The computers are within a limited geographic area, such as a campus or military base.
Network Systems - A group of two or more computer systems linked together.

6. Attached Peripherals
Peripherals are devices, such as a CD-ROM drive printer, mouse, keyboard, printer, monitor, external Zip drive and scanner, fax machines that are attached to the computer and are used either for input or output.

7. Specialized equipment
Certain organizations may require specialized computer equipment that you should be aware of and be able to identify, for instance:
Type of Organization
Specialized Equipment
Sales and Service
Point of Sale machine
Call Centre
Routers, Switches

8. Software
Software is the collective term used to describe computer programs. A program uses a set of instructions that tells the computer what to do. Software is often divided into two categories:
Systems software
Applications software

9. System Software
This describes the computer programs that control the hardware device and ensures that they work together effectively and efficiently.
It includes the operating system and all the utilities that enable the computer to function.

10. Application Software
This describes the programs that allow the computer to be used, so that it can perform a specific function.
For example, an accounting application allows the computer to be used to record accounts receivable and accounts payable transactions.
Examples of applications software include word processing,

11. Software can also be highly specialized and be
specific to certain types of organization such as:
Type of Organization
Specialized Software
Accounting
Peachtree Accounting, AccPac
Web development
Educational
Dream weaver, Microsoft FrontPage
Timetabling software, Online Educational Software

12. Operating System
Operating System – is the most important program that runs on the computer.
Every general purpose computer must have an operating system to run other programs.
Operating systems perform basic tasks such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers.

13. For large systems, such as those found in an IT organization, the operating system has even greater responsibilities, functioning somewhat like a traffic cop by ensuring that different programs and users running at the same time do not interfere with each other.
The operating system is also responsible for security, ensuring that unauthorized users do not access the system.

14. The table below describes two types of operating systems:
Command Line Operating Systems
Graphical User Interface Operating Systems
Unix, MSDOS
Windows (98 – XP), Macintosh OS
NOTE: Although they all look alike, there are some differences between operating systems.
You should be aware of which operating system is running on your computer.
It is also very important to distinguish between the Operating System and Applications Software.

15. IDENTIFY EQUIPMENT, LOCATION AND SERVICE REQUIREMENTS
Organizations may have standardized on certain computing solutions, depending on their type of workflow.
There will very likely be a computer network installed across the organization's site or sites.
Therefore there will be a location for Servers that is usually off-limits to anybody except for IT personnel.
As a member of the IT team, it is your responsibility to know not only where these sites are, but also where each piece of equipment is located.
The organization’s fixed asset register will contain these details.

16. Your company may have established guidelines and schedules for servicing equipment or it may simply follow the manufacturer’s recommendations.
Whichever documentation is available; you must refer to it and put the necessary procedures in place to make it work.
If no guidelines exist, you may want to take the initiative and develop your own which you should get vetted before implementing.
