May specialize in different areas-research and development (r & d), design, manufacturing. Has to be aware of cost, efficiency, safety, environmental factors, as well as engineering aspects. -
Produces the programs which control the internal operations of computers. Converts the system analyst's specification to a logical series of steps. Translates these into the appropriate computer language. Often comply programs from libraries or subprograms, combining these to make up a complete system program. Designs, tests and improves programs for computer-aided design and manufacture, business applications, computer networks and games. -
Advises potential customers about available hardware and sells equipment to suit individual requirements. Discusses computing needs with client to ensure that a suitable system can be supplied. Organizes the sale and delivery and, if necessary, installation and testing. May arrange support or training, maintenance and consultation. Must have sufficient technical knowledge. -
They are responsible for maintaining updating and modifying the software used by a company. Some specialize in software and electronic skills, and knowledge which helps in handling the basic operation of the computers. This involves the use of machine codes and specialized low-level computer languages. Most handle applications software. May sort out problems encountered by users. Solving problems may involve amending an area of code in the software, retrieving files and data lost when a system crashes, and a basic knowledge of hardware. -
Creates the software programs used by computers. May specialize in the internal operating systems using low-level computer language, or in applications programs. May specialize in one aspect of the work, e.g. programming, systems design, systems analysis or cover them all. May support the system through advice and training, providing user manuals, and by helping users with any problems that arise.

Text 1. Strap on some eyephones and you are virtually there
One of the most exciting new areas of computer research is virtual reality. Having been featured in TV sitcoms as well as public television documentaries, virtual reality is merely an ambitious new style of computer interface. Virtual reality creates the illusion of being in an artificial world — one created by computers.
Virtual reality visitors strap on a set of eyephones, 3D goggles that are really individual computer screens for the eyes. Slipping on the rest of the gear allows you not only to see and hear, but also to sense your voyage. The world of virtual reality has been called cyberspace, a computer-enhanced fantasy world in which you move around and manipulate objects to your mind’s content.
When you move your head, magnetic sensors instruct the computer to refocus your eye phones to your new viewpoint. Sounds surround you, and a fiber-optic glove allows you to “manipulate” what you see. You may seek out strange new worlds, fight monsters in computer combat, or strap yourself into the seat of a Star Wars-type jet and scream through cyberspace, blasting all comers to oblivion (computer oblivion, at least). Or, with your stomach appropriately settled, you might even try out the most incredible roller coaster ride you will ever take in your life.
For the disabled, virtual reality promises a new form of freedom. Consider the wheelchair bound paraplegic child who is suddenly able to use virtual reality gear to take part in games like baseball or basketball. Research funded by the government takes a military point of view, investigating the possibility of sending robots into the real conflict while human beings don cyberspace gear to guide them from back in the lab.
Spectrum Holobyte, a computer games development company, announced its first virtual reality computer game for the home during 1991 Christmas season. Imagine yourself suddenly clutching your handheld laser pistol as a giant bird swoops right at you from the age of dinosaurs! Your laser shot goes astray, and you feel yourself suddenly lifted off the ground and carried higher and higher. That’s enough - for some of us it can be virtually too real.

Graphics technology has changed vastly in the nearly three decades since research educators first started passing their knowledge on to students. Introductory computer graphics courses are changing their focus and learning environments. Improvements in hardware and software technology coupled with changes in preparation, interest and abilities of incoming students are driving the need for curriculum change. Past courses focused on low and intermediate level rendering principles, algorithms and software development tools. Many of these algorithms have migrated into hardware. (Though important knowledge for advanced graphics programmers, most graphics applications programmers have no need to study at this level, much as application programmers have no need to study hardware systems of assembly level programming).
Courses need to focus on intermediate and 3D graphics application programmer interface (API) into the instruction.
