Computer Network
A Computer Networkmay be defined as a group of two or more computer systems or peripheral devices, that are connected together are called computer network.
Type of Networks
Personal Area Network (PAN)
This type of network cover very small area such as home or an office ,cabin etc.
it cover the range of less than 10 meter
this type of network uses bluetooth , usb , conection and wifi technology
Local Area Network (LAN)
It is used in office building or educational campus.
Ethernate cable and wifi are used to setup this network.
its range is 10km.
Meteropolitan Area Network(MAN)
This Is larger than Lan and it cover a city . they are used by large organisation
Wide Area Network (WAN)
This is larger type of network . it spas across several cities or countries. or even the whole world WAN is expensive network .
Advantage Of Computer Network
Sharing of Hardware
Sharing of software
Backup
Saves papaer and save time
Cost effective
Disadvantage Of Computer Network
Initial Cost
Virus
security
Major effect of breakdown
Network Architecture
Peer To Peer And
Client Server Network
Peer To Peer Networks
All Computer are equal in capabilities as well as in the use of resources.
Client server Network
A specific computer more powerful than the other computer.
Switching Technique
There are three type of switching technique .
1. Circuit Switching
2. Message Switching
3. Packet Switching
Network Component
Switch
A network Switch Is A device which connect different computer and devices on a network .
Repeater
A Repeater Simply Copies The Information Ariving at its input and retransmits it from the output ,
HUB
Hub Is a networking device which is similar to a switch . but unlike a switch which transmits the information to a particular devices.
Hub is also known as Dumb Switches because hub are comparatively cheaper than switch.
Router
Router is a network device which routes the information around the network.
it also used to connect one network to other network .
Network Topologies
Topology define the geographical, physical or logical arrangement of computer networking devices.
BUS TOPOLOGY - .............
