*NETWORK FULL NOTES *
What is Network : - A Computer network is a group of computer Links to each with their other that enables computer to communication with another computer & share their resources data & applications.
An εx: - of a computer network is the internet which Connect millions of people all over the world.
One of the Computer network two use packet switching, Arpanet was develop in the mid-1960. it is the predecessor of the modern internet. The first Arpanet massage senton October 29 1969.
*Advantage of Network *
1.
Share data information: - one
of the biggest advantages of a network Sharing data an information each of the device
of it. In addition, network allow network two database help with Collaboration
on more Complex work.
2.
Communication - Network gives all user the
ability quickly Communication each other Chart and instant messaging, Email
& videos conferring.
3. Share hardware: - Hardware devices Connected to a network Can be shared with all users. 4. Transferring Money - Being connected to a secure network it allows a person or business to transfer money between Banks and users.
In this Capes there are Several organizations generate the pay all. The pay slip, Transfer money through Computer network into account of the computers.
5. unwanted Sharing: - In Computer network the Sharing is a best feature which is relate to hardware & Software but virus and malware sharing is not Suitable for client therefore Our system will be fridge due to occurrence of the virus.
Network make Sharing information between network and user very easily. unfortunately, that virus and malware have an easier time Spreading between all and Computer and Same network.
6. Complexity: - Networks are Complex and setup for managing network for business and Corporation. which requires a lot of Certification and Experience.
To establish a network our organization Uses different type of wire Connector and ethernet Card. In this situation to Configures our router and gateway our devices. It is more complex for addressing all the devices at the same time.
sz 7. More Expensive – In local area network Connecting no of devices there are a lot of hardware are Used for Computing Less no of computer.
Types of
Computer Network
In complotter network there are different Categories for declaring
types of networks.
i.
Network design. 👈 Click here..( Go to Network design)
ii. Area Network
iii.
Network Topology
iv.
Network protocol
v.
wired vs wireless.
(i)
Type of network According to network design.
ð
In Computer Network there are two ways for
declaring our network.
(ii) Client
server Computing
(iii) Peer-to-peer
computing
(i) Client Server Computer -
=> This model are broadly used in network model. In client
Server network, client and server are differentiated specify server and clients
are present in the Computer network with specific property. In Client Server
network Centralized server is Used to store the data because its management is
centralized.
The term server respond the
service provider but client is called requester for sending our request to the
Centralized system and execute the task.
ii) Peer - TO - Peer Network
=> This model doesn't differential client & Server. In
this network each and every network is itself client and Server. In Peer-to-peer
network each node can do both request and respond for services because each and
every node can either server or client.
ii. Classification of Network according to geographical area network.
- PAN (Personal area network)
- LAN (Local area network1 network)
- CAN (Campus area network)
- MAN (Metropolitan area network)
- SAN (Storage area network)
- WAN (wide area network)
In local area network user Can Share data and resources 300M ( which is the maximum length of router, Hub) in local are network there are number of resource needed for data Communication as for ex- Switch, Communication channel network interface Case and Connects.
3.CAN:- In Computer network Campus area network is the Collection of LAN. because Campus area network communicate all visible LAN to each other Generally Campus area network is used in university or Collage Campus because or LAN are added together in a Centrally System for Communicating head of department principal we each other.
4.MAN:- Metropolitan area network it is a type of network it Communicates a bigger length of can their for we Can say that a Communication Establish within cities for Connecting multiple station of sometime then manage used.
MAN Can be used for variety of purpose including.
(i) Digital Cable television
(ii) Government agencies
(iii) Broadband Connection
(iv) Public Libraries in a city
The above all application Suitable for the metropolitan area
Suitable for Connecting number of Connection in a city at a sometime.
Advantage of MAN
1. Man network
has Several advantage
2. Cost
effective
3. Sending massage
to people in your area it is faster than LAN.
4. It’s communicates
all Lan to each other using fibber channel.
5. A
metropolitan area network Larger than LAN smaller than MAN. This network is
used to Link A Certain geographical areas for creating a Communication with
between to separate LAN Code generally MAN Uses optical fibber constructing
metropolitan network Communication.
5.SAN:- storage Area network is a network of a
storage devices that Can be accept by multiple service on Computers providing
Shared School storage space. Each Computer on the network Can access storage on
the SAN there for a centralized Server provides is Storage Capacity where user
data are Storage centralize places.
In
this age the Could storage is very important because each and every user can Storage
self data in Could storage drive and remotely access by the help of internet
from different place or location.
6.WAN: - WAN Stand for wide area network. In many
ways A WAN similar fashion to a a large skill. The wide aera network is uses TCP/IP
protocol it Cover Larges geographical areas for Communication & sharing resource
& file to each other.
One of
the most bask way to think about wide aera Network in understanding. How &
Why isn’t Connect smaller network. In another word wide area network is
Collection on LAN, CAN, MAN, SAN.
The best Example of WAN is and internet because internet uses to server
in world-wide network for sharing data all file is also sharing resource from
one user to other. In Local area network it Uses a single User martin and
router generally gateway Connection point to Internet but wide area network there
are multiple station are connected with same is server for sharing data among
those station.
