• Work which has to do with networks.• The system administrator manages the network.• Takes care of the resources in the network.• Is a means of Human Interface within the

network.• The System Administrator supervises anything

that happens within the system (the network).

• Repairs must be made in case of errors or malfunctions.

• Carries out both preventive and corrective maintenance.

• Responsible to install new hardware.

Lab Technician

• Work which is mostly concerned with hardware.

• Must supervise computer installation.• Is responsible of individual pieces of

equipment, and must operate them.• Responsibilities include: loading the

system, un/loading peripherals, monitor computer’s performance, and cleaning the hardware.

Computer Operator

• System Analysis is the beginning of a great line of work.• Analysts are usually asked to design a computer system

for whatever task is needed.• Analysts must collect information, and consider many

factors, on which the availability of the program depends. E.g.: what is needed, feasibility of the needed system, budget of the company, etc.

• System Analysts usually work in groups, depending on the size of the project they work on. The System Analysts are only one department out of the many involved with computerisation of systems.

System Analyst

• Programming is the phase that comes after analysis.• Programmers work on the design made by the

analyst(s), to create the needed program, or system.• The programming department usually consists of a chief

programmer, as well as junior programmers.• The programmers, especially the chief programmer, help

with the design phase of analysis. This is so that ideas can be passed from the programmers, which have to code these ideas later.

• Programmers must debug their programs, and test them until they work properly.

Programmers

• The IT Trainer is also involved with computerisation.

• Some of the users may have no knowledge of computer usage.

• The IT Trainer’s job is to teach and train these users.

• The IT Trainer must teach users how to use the computers, and also how to use the new system.

• It is vital that IT trainers have a good communication skill.

IT Trainer

• Maintenance Engineers are usually provided by the computer manufacturer.

• They are involved with the maintenance of the computer system in use.

• Also, they are usually called on advice when new hardware is going to be bought, to check whether it is compatible with the current system.

Maintenance Engineer

• Data Entry Clerks have the job of typing in data; which may be either the codes created by the programmers, or documentation on various parts of the system.

• No computing skill is needed, but it is demanded that Data Entry Clerks have a high skill in typing and accuracy.

• Punctuality is very important, and it is usually up to the Data Preparation Supervisor to see that the staff are doing their jobs at the right times and in the right ways.

Data Entry Clerk
