1

Local Area Network (LAN)

A computer network that connects devices within a limited area, such as a home, office, or campus.

New cards
2

Bus Topology

All devices are connected to a single cable, forming a linear network. Advantages:Easy to install and cost-effective. Disadvantages:Limited scalability and potential for collisions.

New cards
3

Star Topology

All devices are connected to a central hub or switch. Advantages:Easy to add or remove devices without affecting the network. Disadvantages:Dependent on the central hub and requires more cabling.

New cards
4

Ring Topology

Devices are connected in a circular manner, forming a closed loop. Advantages:Equal access to network resources and no collisions. Disadvantages:Failure of a single device or cable can disrupt the entire network.

New cards
5

Switched Topology

Devices are connected to a central switch, which manages data flow. Advantages:Efficient data transmission and no collisions. Disadvantages:Costlier due to the need for switches and failure of the central switch affects the entire network.

New cards
6

Daisy Chain Topology

Devices are connected in a linear manner, one after another. Advantages:Simple and easy to implement. Disadvantages:If any device or cable fails, the entire network is affected and limited scalability.

New cards
7

Hierarchy Topology

Combination of different topologies, typically a mix of star and bus or star and ring. Advantages:Provides flexibility and scalability. Disadvantages:Complex to design and implement and requires more cabling and additional hardware.

New cards
8

Wide Area Networks (WAN)

A computer network that spans a large geographical area, connecting multiple local area networks (LANs) or other WANs.

New cards
9

Peer-to-Peer Topology

Each node in the network can act as both a client and a server. Offers high scalability and fault tolerance.

New cards
10

Ring WAN Topology

Nodes are connected in a circular manner, forming a ring. Offers simplicity and equal access to all nodes.

New cards
11

Star Topology

Consists of a central node connected to multiple peripheral nodes. Offers easy management and fault isolation.

New cards
12

Full-Mesh Topology

Each node is directly connected to every other node in the network. Offers high redundancy and fault tolerance.

New cards
13

Partial Mesh Topology

Only a subset of nodes are directly connected to each other. Offers a balance between cost and redundancy.

New cards
14

Two-Tiered Topology

Consists of access layer and distribution layer. Offers scalability, flexibility, and centralized management.

New cards
15

Hybrid WAN Topology

Combines multiple topologies to meet specific requirements. Offers flexibility, scalability, and cost-effectiveness.

New cards
16

Advantages of WAN

Geographical flexibility, resource sharing, centralized management, and scalability.

New cards
17

Disadvantages of WAN

Cost, complexity, reliability, and security vulnerabilities.
