Network:

→A network refers to a collection of interconnected devices or nodes that can communicate with each other and share resources.

Basic Terminology

  1. Nodes: Nodes are the individual devices or computers connected to the network. Each node has a unique address that allows it to be identified on the network.
  2. Links: Links refer to the physical connections (wires or wireless channels) between nodes that facilitate data transmission.
  3. Protocols: Network protocols are a set of rules and conventions that dictate how data is transmitted and received over the network. Examples include TCP/IP, HTTP, SMTP, and FTP.
  4. Topology: Network topology refers to the physical or logical arrangement of nodes and links in a network. Common topologies include bus, star, ring, and mesh.
  5. Hop: In networking, a "hop" refers to a single step or jump that data packets take from one network node to another as they travel across a network. Each hop involves the transmission of data from one device to the next, usually through routers or switches, until the data reaches its destination. Hops are used to measure the distance and route that data travels, and they contribute to the overall latency and performance of network communication.
  6. LAN (Local Area Network): A LAN covers a limited geographical area, such as a home, office, or campus. LANs allow devices to communicate and share resources within the same local area.
  7. WAN (Wide Area Network): A WAN spans a larger geographical area, connecting multiple LANs over long distances. The internet is an example of a global WAN.
