What is computer networking?



Computer networking is defining as the interconnection of computer devices that can exchange data and share resources with each other. These connected devices use a system of rules called communication protocols to transmit information via physical or wireless technologies.

 

What are the types of computer network architecture?

Computer network design falls into two wide categories:

 

1. Client-server architecture

In client server architecture, nodes may be servers or clients. Server nodes provide resources like processing power, data, or memory to client nodes.  In Server nodes we can also manage client node activity Clients can interface with each other, but they do not share resources. For example, some computer devices in undertaking networks store data arrangement settings. These devices are called as servers in the network. Clients can access this data by building a request to the server machine.

2. Peer-to-peer architecture

In Peer-to-Peer architecture, connected computers have equal privileges and power. Every device in the computer network can behave as either client or server. Each peer can share several of its resources, like processing power and memory, with the entire computer network,e.g. some companies use p-2-p architecture to host memory-consuming applications, e.g. 3-D graphic rendering, over multiple digital devices.

Types of networking

There are two types of computer networking:

1.       wired networking.

2.        wireless networking.

 

1.Wired networking

Wired networking requires the use of a physical medium for transfer between nodes. Copper-based Ethernet cabling, accepted due to its low cost and strength, is commonly used for digital communications in home and business or, optical fiber is used to transfer data overlarge distances and at faster speeds, but it has various tradeoffs, including higher costs and weaker components.

 

 

2.Wireless networking.

Wireless networking uses radio waves to transfer data over the enabling devices, air to be connected to a network without any cabling. Wireless LANs are the most widely and well-known deployed form of wireless networking. Alternatives include satellite, Bluetooth sand microwave, among others.

As a general rule, wired networking offers greater reliability, speed and security compared to wireless networks; wireless networking tends to provide more mobility, flexibility and scalability.
