Summary

In this lesson, we explore the concept of computer networks, which consist of interconnected computers and devices. The types of networks are categorized based on data distribution methods (centralized and distributed), functional relationships (client-server and peer-to-peer), and coverage areas (LAN, MAN, and WAN). Additionally, networks are classified based on connection methods: wired and wireless networks. LAN networks cover smaller areas, while MANs span cities, and WANs connect across islands, countries, and continents. This overview introduces the core concepts, enabling learners to understand the fundamental types and operations of computer networks.

Takeaways

• 😀 A computer network is a collection of computers and devices connected to each other to share data and resources.
• 😀 A centralized network has client computers that access data from a central server.
• 😀 A distributed network is a combination of several centralized networks, offering more interconnectivity.
• 😀 A client-server network consists of a server providing data and resources to multiple client computers.
• 😀 A peer-to-peer network allows computers to share resources directly without relying on a central server.
• 😀 LAN (Local Area Network) is a small network that connects computers within a limited area, like a building or office.
• 😀 MAN (Metropolitan Area Network) spans a city or region, linking multiple LANs together.
• 😀 WAN (Wide Area Network) covers a vast area, connecting networks across cities, countries, or continents.
• 😀 Wired networks use cables to physically connect computers and share data reliably.
• 😀 Wireless networks use electromagnetic waves to transmit data signals without the need for physical cables.

Q & A

What is a computer network?

A computer network is a collection of computers and other devices connected to each other, allowing them to exchange data and resources.

What are the two main types of computer networks based on data distribution methods?

The two main types of computer networks based on data distribution methods are centralized networks and distributed networks.

What is a centralized network?

A centralized network consists of client computers and server computers, where client computers access data and resources from the server computer.

What is a distributed network?

A distributed network is a combination of several centralized networks, where the data is distributed across multiple servers and clients.

What are the two types of computer networks based on functional relationships?

The two types of computer networks based on functional relationships are client-server networks and peer-to-peer networks.

How does a client-server network work?

In a client-server network, the server computer provides resources and data to the client computers, which request and receive the data.

What is a peer-to-peer network?

In a peer-to-peer network, all computers have equal roles, meaning there is no clear distinction between client and server; each computer can both provide and receive data.

What are the three types of computer networks based on their coverage area?

The three types of computer networks based on coverage area are LAN (Local Area Network), MAN (Metropolitan Area Network), and WAN (Wide Area Network).

What is the difference between LAN, MAN, and WAN?

A LAN covers a smaller area, such as a room or office; a MAN covers a larger area, like a city; and a WAN covers an even wider area, such as connecting multiple cities, countries, or even continents.

What is the difference between wired and wireless networks?

Wired networks use cables to connect computers, while wireless networks use electromagnetic waves to transmit data signals without the need for physical cables.

Can you explain how LAN, MAN, and WAN are connected geographically?

In the example given, a LAN network is limited to a single building or room, a MAN connects multiple LANs across a city, and a WAN connects multiple MANs across large geographic areas, such as different cities or even countries.

How do wired networks transmit data?

Wired networks transmit data using physical cables, such as Ethernet cables, to establish connections between computers and facilitate data exchange.

How do wireless networks transmit data?

Wireless networks transmit data using electromagnetic waves, which allow computers to send and receive information over the air, without needing physical cables.
