Components Of A Network
What Are the 6 Main Components Of A Network
Definition of a Switch
What Is A Hub
A USB hub is a device that expands a single USB port into several so that there are more ports available to connect devices to a host system,USB hubs are often built into equipment such as computers, KeyBoards, Monitors or printers. When such a device has many USB ports they all usually stem from one or two internal USB hubs rather than each port having independent USB circuitry.
What Is A Server
ommon types of network servers include:
- Web servers
- proxy servers
- FTP servers
- online game servers
Network interface controller
A network interface controller (also known as a network interface card, network adapter, LAN adapter and by similar terms) is a computer hardware component that connects a computer to a computer network.
Early network interface controllers were commonly implemented on expansion cards that plugged into a computer bus; the low cost and ubiquity of the Ethernet standard means that most newer computers have a network interface built into the motherboard.

A Ring Network
What is It
A ring network is a network topology in which each node connects to exactly two other nodes, forming a single continuous pathway for signals through each node - a ring. Data travels from node to node, with each node along the way handling every packet.
Because a ring topology provides only one pathway between any two nodes, ring networks may be disrupted by the failure of a single link. A node failure or cable break might isolate every node attached to the ring.
A Star Network
A Star Network
Better performance: star topology prevents the passing of data packets through an excessive number of nodes. At most, 3 devices and 2 links are involved in any communication between any two devices. Although this topology places a huge overhead on the central hub, with adequate capacity, the hub can handle very high utilization by one device without affecting others.
High dependence of the system on the functioning of the central hub. Failure of the central hub renders the network inoperable
What IS The Bus Network
- Ease of installation.
- Simple and cheap.
- If one computer fails it does not affect the other computers.
- Printers can be shared.
- If the main cable fails, all the other sources will die
- Reconfiguration, fault isolation and installation of new devices tend to be difficult since the network is designed to be most efficient during installation.
- The longer the distance covered by a signal along the shared communication line the greater the heat is produced due to energy being transformed to heat making the signal weaker the farther it travels.
