BASIC COMPONENTS OF COMPUTER

A network has 5 basic components. Thay are :
- clients
- servers
- channels
- interface devices
- operating systems.
SERVERS : Servers or Host computers are are
powerful computers that store data or applications
and connect to resources that are shared by the
users of a network.
CLIENTS : Client is the computer used by the users
of the network to access the servers and shared
resources (such as hard disks and printers). So, a
personal computer is a client.
CHANNELS : The technical name of channels is
network circuit. It is the pathway over which
information travels between the different computers
(clients and servers) that comprise the network.
INTERFACE DEVICES : The devices that connect
clients and servers (and sometimes other networks)
to the channel are called interface devices. The
common examples are modems and network
interface cards.
OPERATING SYSTEMS : This is the Network
Software. It serves purpose that the operating
system serves in a stand-alone computer.

Linux Facts For You...
1. Linux is not an OS, but it is the kernel, GNU
Linux is the OS and it comes in several hundred
flavours.
2. Linux Kernel was written by a 21 year finnish
college student as a part of his hobby. Yup! His
name is Linus Torvalds.
3. Torvalds created Linux based on GNU General
Public License (GPL). Perhaps Torvalds would
have never written his own kernel if GPL would be
having it’s own kernel and driver.
4. Major part of today’s Linux kernel is written in C
programming language and assembly language and
only 2% of today’s kernel contains code written by
Torvalds.
5. A Standard Linux Kernel of today has over 10
Million lines of code and it grows at the rate of 10%
every year. About 4500 lines of codes are added
and 1500 lines of code are changed everyday.
Initially in 1991, Linux kernel version 0.01 was
released with 10239 lines of code.
6. A guy named William Della Croce Jr. registered
the name Linux and demanded royalty for using its
name and mark. However he agreed to handover
the trademark to Linus, later.
7. The Linux kernel’s official mascot is a penguin
named Tux, abbreviation of tuxedo. The idea that
Linux had a pet penguin comes from Linus Torvalds
himself.
