- 1What is a computer network?A computer network or data network is a digital telecommunications network which allows nodes to share resources
- 2What is a WANA wide area network is a telecommunications network or computer network that extends over a large geographical distance.
- 3what is a LANA local area network is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building.
- 4What are the advantages of a computer network?printers, scanners and copiers or sharing software between multiple users, saves money.
- 5What is the purpose of a NIC?The NIC contains the electronic circuitry required to communicate using a wired connection (e.g., Ethernet) or a wireless connection (e.g., WiFi). A network interface card is also known as a network interface controller, network adaptor, or Local Area Network (LAN) adaptor.
- 6What is the purpose of a Router?The main purpose of a router is to connect multiple networks and forward packets destined either for its own networks or other networks. A router is considered a layer-3 device because its primary forwarding decision is based on the information in the layer-3 IP packet, specifically the destination IP address.
- 7What is the purpose of a Hub?A hub, also called a network hub, is a common connection point for devices in a network. Hubs are devices commonly used to connect segments of a LAN. The hub contains multiple ports. When a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
- 8What is the purpose of a Switch?The basic function that any switch is supposed to perform is to receive information from any source connected to it and dispatch that information to the appropriate destination only. This thing differentiates switches from hubs. Hub gets the information and forwards that to every other device in the network.
- 9What is the purpose of a WAP?A wireless access point (WAP) is a hardware device or configured node on a local area network (LAN) that allows wireless capable devices and wired networks to connect through a wireless standard, including Wi-Fi or Bluetooth.
- 10What is the difference between a Hub and a Switch?Function of a switch vs. a hub. A switch is used to connect various network segments. A network switch is a small hardware device that joins multiple computers together within one local area network (LAN). A Hub connects multiple Ethernet devices together, making them act as a single segment.
