Types of computer network | Difference between LAN CAN MAN and WAN | Basics of computer Network 2024

Summary

In this video, Visay Gupta introduces the fundamentals of computer networks, defining them as interconnections of multiple computers and peripherals that facilitate information sharing. He explains various types of networks, including Local Area Networks (LANs), Campus Area Networks (CANs), Metropolitan Area Networks (MANs), and Wide Area Networks (WANs), highlighting their characteristics, coverage areas, and data transmission rates. Gupta also mentions the Open Systems Interconnection (OSI) model, which governs communication formats and rules between computers. The video serves as an informative guide for those looking to understand the basics of networking.

Takeaways

• 😀 A computer network is an interconnection of two or more computers and peripherals, enabling information sharing.
• 💻 Networks facilitate communication between devices like PCs, printers, and smartphones using cables or modems.
• 📏 The OSI model defines the rules and formats for how computers communicate over a network.
• 🌐 LAN (Local Area Network) covers a small area (up to 1 km) and typically connects devices in homes or offices.
• 🏫 CAN (Campus Area Network) connects multiple LANs within a limited area, such as schools or hospitals, covering 5 to 10 km.
• 🏙️ MAN (Metropolitan Area Network) links networks across a city and supports both data and voice transmission, covering up to 200 km.
• 🌍 WAN (Wide Area Network) spans large geographical areas (over 100 km) and connects devices via public networks, with the internet as a prime example.
• ⚡ LANs have data transmission rates ranging from 10 to 100 Mbps, using IEEE 802 standards.
• 📺 Examples of MAN include television cable networks that connect multiple locations within a city.
• 📅 The next video will explain the differences between LAN, CAN, MAN, and WAN for a better understanding.

Q & A

What is a computer network?

A computer network is an interconnection of two or more computers and peripherals, allowing users to share and transfer information.

What does the OSI model represent in computer networking?

The OSI model, or Open Systems Interconnection model, explains the formats and rules that computers follow to communicate with each other.

What is a Local Area Network (LAN)?

A LAN is a computer network that covers a small area, typically connecting computers and workstations within a one-kilometer radius.

What are the data transmission rates for a LAN?

The data transmission rates for a LAN range from 10 to 100 Mbps and adhere to the IEEE 802 standard.

Can you explain what a Campus Area Network (CAN) is?

A CAN is a network made up of two or more LANs within a limited area, often found in institutions like schools and hospitals, covering an area of 5 to 10 kilometers.

What is a Metropolitan Area Network (MAN)?

A MAN interconnects networks within a city and supports data and voice transmission, covering an area of up to 200 kilometers.

How does a Wide Area Network (WAN) differ from other networks?

A WAN spans a large geographical area, such as states or countries, and connects multiple computers or LANs through public networks like telephone systems or satellites.

What is a common example of a WAN?

The internet is the most common example of a WAN, covering vast geographical areas beyond 100 kilometers.

What role do devices like switches and hubs play in computer networks?

Devices like switches and hubs act as centralized points that connect various peripheral devices within a network.

What can viewers expect in the next video?

In the next video, the presenter will discuss the differences between LAN, CAN, MAN, and WAN.
