Study Notes
Communication in Computer Networks
- Communication in computer networks refers to the exchange of data, instructions, or information between devices, systems, or networks.
Types of Communication
- Half-duplex communication: allows data transfer in both directions, but not simultaneously.
- Full-duplex communication: allows data transfer in both directions simultaneously.
Personal Area Network (PAN)
- A PAN is a computer network that connects devices centered around an individual, typically within a range of 10 meters.
- The range of a PAN is typically around 10 meters.
Types of Computer Networks
- The three main types of computer networks based on their size are:
- LAN (Local Area Network): connects devices in a limited geographical area, such as a home, office building, or campus.
- MAN (Metropolitan Area Network): connects devices in a metropolitan area, such as a city or town.
- WAN (Wide Area Network): connects devices over a large geographical area, such as a country or continent.
Network Communication
- Network communication refers to the exchange of data, instructions, or information between devices, systems, or networks.
Network Topologies
- Point-to-point connection: a direct connection between two devices.
- Multipoint connection: a connection between multiple devices.
- Bus topology: a single cable connects all devices, allowing for easy installation and removal of devices.
- Disadvantage of ring topology: if one device fails, the entire network fails.
Network Protocols and Technologies
- FTP (File Transfer Protocol): a protocol used for transferring files over a network.
- Network protocol: a set of rules and standards that govern data communication over a network.
- A network protocol defines the format, timing, and error-checking systems for data exchange.
