Computer Network

Computer Network: A computer network is a collection of computers and other devices connected together to share resources and communicate with each other. These networks can range from small, local setups within a single building to vast, global networks like the internet.

Packet

Packet: A packet is a small unit of data transmitted over a network. It contains both the actual data being sent and information about its destination, source, and how it fits into the larger message being transmitted.

Local Area Network (LAN)

Local Area Network (LAN): A local area network is a network that covers a small geographic area, typically within a single building or campus. LANs allow connected devices to share resources such as files, printers, and internet access.

Wide Area Network (WAN0

Wide Area Network (WAN): A wide area network is a network that spans a large geographic area, connecting multiple LANs or other networks together. WANs enable long-distance communication between devices and are often used for internet connections.

Node

Node: A node is any device connected to a network, such as a computer, printer, or router. Each node has a unique address and can send or receive data over the network.

Media Access Control (MAC): Media Access Control is a protocol used to uniquely identify devices on a network. Each network interface card (NIC) has a unique MAC address assigned to it, allowing devices to communicate with each other.

Media Access Control (MAC)

IP Address: An IP address is a unique numerical label assigned to each device connected to a network that uses the Internet Protocol for communication. IP addresses are used to identify and locate devices on a network.

IP Address

Bus Topology: Bus topology is a network architecture in which all devices are connected to a single cable, called a bus. Data is transmitted along the bus, and each device receives the data intended for i

Bus Topology

Ring Topology: Ring topology is a network architecture in which devices are connected in a circular fashion, forming a ring. Data travels around the ring until it reaches its destination.

Ring Topology

Network Token: A network token is a special packet used in token-based network architectures, such as Token Ring networks. The token controls access to the network, ensuring that only one device can transmit data at a time.

Network Token

Star Topology: Star topology is a network architecture in which devices are connected to a central hub or switch. All communication between devices passes through the central hub.

Star Topology

Tree Topology: Tree topology is a network architecture that combines characteristics of both bus and star topologies. Devices are arranged in a hierarchical tree structure, with branches connecting to a main trunk.

Tree Topology

Protocol: A protocol is a set of rules and conventions that govern how data is transmitted and received over a network. Protocols define standards for communication, ensuring compatibility between different devices and systems.

Protocol

Peer-to-Peer Architecture: Peer-to-peer architecture is a network model in which all devices have equal status and can act as both clients and servers. Each device can share resources directly with other devices without the need for a centralized server.
