Study Notes
Computer Network Fundamentals
- A computer network is a group of interconnected devices that communicate with each other to share resources and exchange data.
Purpose of a Computer Network
- The primary purpose of a computer network is to enable communication, resource sharing, and information exchange between devices.
Connecting Devices
- Ethernet technology is commonly used to connect devices in a computer network, using twisted-pair or fiber optic cables.
LAN (Local Area Network)
- A LAN is a computer network that spans a small geographic area, typically within a building or campus, and is used to connect devices in a limited area.
Networking Devices
- A switch is a networking device that operates at the Data Link Layer (Layer 2) of the OSI model, responsible for forwarding data packets between devices on the same network.
DNS (Domain Name System)
- The purpose of DNS in a computer network is to translate human-readable domain names into IP addresses that devices can understand, enabling devices to communicate with each other.
