Programming languages.

Hi!. Now we all live in period when the information plays a leading role. This became possible due to computer technologies. Computers are controlled by humans with a help of programs. Programs are created with programming languages. They are devided into 2 types :

Low Level Programming languages: representative of this type is Assambler. Code written on this language is very difficult to understand . But it’s a universal language that might be applied almost everewhere.

High Level Programming languages: They are C++ , Delphi , Basic, Pascal , and others.Code is quite understandable. Each of them has it’s own advantages and disadvantages.

COMPUTER SYSTEM ARCHITECTURE

As we know all computer systems perform the functions of inputting, storing, processing, controlling, and outputting. Now we'll get acquainted with the computer system units that per­form these functions. But to begin with let's examine computer systems from the perspective of the system designer, or archi-

tect.

It should be noted that computers and their accessory equip­ment are designed by a computer system architect, who usually has a strong engineering background. As contrasted with the analyst, who uses a computer to solve specific problems, the computer system architect usually designs computer that can be used for many different applications in many different business. For example, the product lines of major computer manufactur­ers such as IBM, Digital Equipment Corporation and many others are the result of the efforts of teams of computer system architects.

Unless you are studying engineering, you don't need to be­come a computer system architect. However, it is important that as a potential user, applications programmer or systems analyst you understand the functions of the major units of a computer system and how they work together.
