Computer Networking
What is Networking?
Networks are simply things that are connected. For example, your friendship circle: you are all connected because of similar interests, hobbies, skills and sorts.
Networks can be found in all walks of life:
- A city’s public transportation system
- Infrastructure such as the national power grid for electricity
- Meeting and greeting your neighbours
- Postal systems for sending letters and parcels
but specifically, Computer networking refers to the practice of connecting computers and other devices together to share resources, exchange information, and communicate with each other. It is a fundamental concept in the field of information technology and is essential for enabling various forms of communication and data sharing in both local and global contexts. Networking can be categorized into different types and can involve various technologies and protocols.
Type of networks
there are three types of networks:
- LAN: Local Area Network
- MAN: Metropolitan Area Network
- WAN: Wide Area Network
Local Area Network (LAN)?
LANs are basically used to connect devices within a limited area, such as a home, office, coffee shop or campus. Ethernet cables and Wi-Fi are common technologies for LANs.
Metropolitan Area Network (MAN)?
The Metropolitan Area Network (MAN) is a network type that covers the network connection of an entire city or connection of a small area. The area covered by the network is connected using a wired network, like data cables.
Wide Area Network
A wide area network also known as (WAN) is a large network of information that is not tied to a single location. WANs can facilitate communication the sharing of information and much more between devices from around the world through a WAN provider.
networking is a field and we can not cover it all but we cover networking that is important in Cyber Security.
that’s all guys for today I hope you enjoyed that topic and the next topic is what is the internet?
