Computers in research
Computers help in the building of spacecraft, and they assist flight engineers in launching, controlling and tracking the vehicles. Computers also are used to develop equipment for exploring the moon and planets. Computers have been of tremendous help to researchers in the biological, physical and social sciences. Astronomers use computers to guide telescopes and to process photographic images of planets and other objects in space.

Computers in education
There are many computer classes at our technical school. We can get basic computer skills for our future specialty there. We study some applications: Word 7.0, Excel 7.0, NetWare and others. At our computer lessons we print texts, draw graphs and electronic tables, create databases, translate texts, create new files and prepare projects. Our students like computer lessons very much because computers can do many lessons more interesting and convincing.
Today computers can store huge amount of information on magnetic media and any item of this information can be obtained in a few milliseconds and displayed or printed for the user. We all use PCs to make our life easier.
