9. Benefit of a Computer Network
∗ We have 100 pc’s

∗ It’s make costs higher and higher
∗ What should we do to prevent from this loses?
∗ What is the solution
10. Solution is here
∗ Make a Computer Network.
∗ Just we need one printer and one CD ROM and
other device.
∗ How it’s possible?
∗ With Network every thing is possible.
∗ Share those devices among all computers.
∗ So all computers can use those devices.
∗ And costs are will goes down.
11. Why? Use a Computer
Network!
∗ In computers network we can (share nodes, clients,
workstations and servers)
∗ can share:
∗ Files
∗ Resources
∗ programs
12. Shareable & Non Shareable
Shareable
1: Hard ware 2: Soft ware
1: Printer, CD Room, Flash, Floppy, Modem.
2: Any S/w
Non Shareable
Mouse, Keyboard, Camera, MIC & etc.
13. Network terminology
This is
This is a
a Node
What is Node? Node
› Every device
attached to a
network.
› Every device at the
end of link.
› Every device (if it
will be directly
connected or This is
a
indirect) Node
14. Cont..
∗ What is Link?
∗ The path available between two nodes.
∗ The nearest path throw which two computers will
connect with each other.
∗ Communication media.
∗ The physical path between tow nods.
