Computers

Computer engineering is now the most rapidly grow­ing field. The electronics of computers involve engineers in design and manufacture of memory systems, of cen­tral processing units, and of peripheral devices. The field of computer science is closely related to computer engi­neering; however, the task of making computers more «intelligent» (artificial intelligence), through creation of sophisticated programs or development of higher level machine languages or other means, is generally regarded as the aim of computer science.

One current trend in computer engineering is micro­miniaturization. Engineers try to place greater and greater numbers of circuit elements onto smaller and smaller chips. Another trend is towards increasing the speed of computer operations through the use of parallel processors and superconducting materials.

Mechanical Engineering

Engineers in this field design, test, build, and oper­ate machinery of all types; they also work on a variety of manufactured goods and certain kinds of structures. The field is divided into (1) machinery, mechanisms, materials, hydraulics, and pneumatics; and (2) heat as applied to engines, work and energy, heating, ventilat­ing, and air conditioning. The mechanical engineer, therefore, must be trained in mechanics, hydraulics, and thermodynamics and must know such subjects as metallurgy and machine design. Some mechanical en­gineers specialise in particular types of machines such as pumps or steam turbines. A mechanical engineer de­signs not only the machines that make products but the products themselves, and must design for both economy and efficiency. A typical example of modern mechani­cal engineering is the design of a car or an agricultural machine.
