Understanding the fundamentals of computer networks
A computer network is a group of computers and other devices that are connected together to share resources and communicate with each other.
Types of Networks
- LAN (Local Area Network): A network confined to a small geographic area, like a home, office, or building.
- WAN (Wide Area Network): A network that spans a large geographic area, like a city, country, or even globally.
- MAN (Metropolitan Area Network): A network that spans a city or large campus.
- PAN (Personal Area Network): A network for connecting devices centered around an individual person.
Network Topologies
Star Topology
All devices connect to a central hub or switch.
Bus Topology
All devices connect to a single cable or backbone.
Ring Topology
Devices connect in a circular pattern.
Mesh Topology
Devices connect to multiple other devices for redundancy.
