• Job usually involved with networks.
• Has the job of checking that all computers
in the network are in good working order.
• Repairs must be made in case of errors or
malfunctions.
• Carries out both preventive and corrective

Computer Operator
• Work which is mostly concerned with
hardware.
• Must supervise computer installation.

equipment, and must operate them.
• Responsibilities include: loading the
system, un/loading peripherals, monitor
computer’s performance, and cleaning the
hardware.
System Analyst
• 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.
Programmers
• 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.
IT Trainer
• 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.

• It is vital that IT trainers have a good
communication skill.
Maintenance Engineer
• 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.
Data Entry Clerk
• 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
