Q & A on Networking

This guide offers a concise overview of networking fundamentals, covering essential concepts such as the definition of networking, types like Local Area Networks (LAN) and Wide Area Networks (WAN), and the advantages of LANs including speed and security. It explains critical components such as protocols, network hardware, switches, routers, cabling, and topologies. Additionally, it discusses the role of Network Operating Systems (NOS) in managing multiple computers. Perfect for beginners seeking to grasp the basics of computer networking.

  1. Q & A on Networking

  2. Question No. 1 What is Networking? • Two or more computers that are linked in order to share • Resources (such as printers & CDs) • Exchange files • Allow electronic communications

  3. Question No. 2 What are two basic types of Networking? • Local Area Network (LAN) • Confined to relatively small geographic area • Wide Area Network (WAN) • Connect larger geographic area

  4. Question No. 3 What are the advantages of LAN? • Speed • Cost • Security • Centralized Software Management • Resource sharing

  5. Question No. 4 What is a Protocol? • A Protocol is a set of rules that governs the communication between computers on a network

  6. Question No. 5 What is Network Hardware? • Network hardware includes all computers, peripherals, interface cards and other equipment needed to perform data-processing and communication within the network

  7. Question No. 6 What is a Switch? • A Switch is a device that provides a central connection point for cables from workstations, servers, and peripherals

  8. Question No. 7 What is a Router? • A router translates information from one network to another • it is similar to a super-intelligent bridge. • Routers select the best path to route a message, based on the destination address and origin. • The router can direct traffic to prevent head-on collisions, and is smart enough to know when to direct traffic along back roads and shortcuts

  9. Question No. 8 What is Network Cabling? • Cable is the medium through which information usually moves from one network device to another

  10. Question No. 9 What is a Topology? • The physical topology of a network refers to the configuration of cables, computers, and other peripherals. • Physical topology should not be confused with logical topology which is the method used to pass information between workstations

  11. Question No. 10 What is a Network Operating System? • Unlike operating systems, such as Windows, that are designed for single users to control one computer, network operating systems (NOS) coordinate the activities of multiple computers across a network. • The network operating system acts as a director to keep the network running smoothly
