 Computer Basics and Programming

Computer is composed of three major components :

(i)                  Hardware (which we can touch upon)

(ii)                (ii) Software (operations, instructions etc)

(iii)               Liveware (users/Human beings who interact with H/W & S/W)

(iv)               Software can be classified in two main categories

(v)                (a) System Software which is used to run computer system

(vii)              System software can be divided into the following types.

(viii)            (i) Operating System which is a group of programs that acts as an interface between the user and machine and as a resource manager

(ix)              (ii) Translators which convert the programs in any language into machine language.

(x)                 (iii) Loaders/Linkers

(xi)              (iv) System Utilities Translators are of two types ;
