C Programming Tutorial ( Part 2 )

Programming Basic :

PCs could be linked together in computer networks over
telephone lines or in local area networks (LANs) within an
organization
Information is shared easily across computer networks, where
computers are called servers (e.g. file servers, database servers,
web servers, etc.) offer capabilities that may be used by client
computers distributed throughout the network
C program is widely used for writing software for operating
systems, computer networking, and for client/server applications

Programmers write instructions in various programming
languages, some directly understandable by computers and
others require intermediate translation steps
Programming languages can be divided into three general
classes:
1 Machine languages
2 Assembly languages
3 High-level languages

C Programming Tutorial ( Part 1 )

Programming Basic :
A computer is a device that can perform computations and make
logical decisions billions of times faster than human beings can,
e.g. many personal computers (PCs) can perform several billion
additions per second.
Computers process data under the control of sets of instructions
called computer programs
These programs guide the computer through orderly sets of
action specified by people called computer programmers
A computer consists of various devices (e.g. keyboard, screen,
mouse, hard disk, memory, etc.) referred to as hardware
The programs that run on a computer are referred to as
software, e.g. Microsoft word, anti-virus program, etc.
