Networking working on Network Mediator devices like Switches, Routers, WIFI, Firewall, and Bridge.

 

Importance of Networking?

Networking is the main base for any organization. Without networking, nothing will work properly. Like if you are a Software Developer, Website Developer, Application Developer, Server Developer, Database Developer, or Mobile Application Developer, and if you create an application without networking not a single client will be able to use your resources.

Play Multiplayer Games.

 

How does Computer Network Work?

Computer Networking working on packet switching. Packets are switching from source to destination. If the packet drop user will not receive any data from the source. Network service runs on specific service and port numbers.

Types of Computer Network?

Computer Network design on network types. Here we brief about some networking types.

 

- Local Area Networks (LAN):- Local Area Network design for Limited area networks like school colleges or small companies.

 

- Personal Area Networks (PAN):- Personal Area Network design for a personal network like Infrared or Bluetooth. PAN access in the limited area network.

 

- Home Area Networks (HAN):- Home Area Network design to connect home appliances like TV, Fridge, Washing machine, WIFI Router, and Smartphone.

 

- Wide Area Networks (WAN):- Wide Area Network design to connect large geographical areas.

 

- Campus Networks (CAN):- Campus Area Network design to connect specific campus areas like schools or colleges.

 

- Metropolitan Area Networks (MAN):- It connects city to city.

 

- EPN Network:- Enterprise Private Network. It connects various sites from different locations.

 

- Internetworks Network:- Internet Network. Multiple Connection Connect to the Internet at a time.

 

- BBN Network:- Backbone Network. Provide specific information path to communicate

 

Advantages of Computer Network?

- File-Sharing:- Share File and Folder easily from any computer. Single and Multiple file sharing. File sharing with and without authentication users can access.

 

- Resource Sharing:- Software, Application, or ERP system users can access through the network.

 

- Sharing Internet Connection:- Single Internet connection can be shared with multiple users through the network.

 

- Central Data Storage:- Server or client Data backup can store on a single server through the network.

 

- Authentication & Security:- Data sharing and internet surfing will authenticate with security monitoring.
