When two or more computers are joined, a network is formed. Data packets are used to send files over a network. Different topologies can be used to create networks. In order for computers to communicate with one another, hardware and networking is required. Routers, hubs, switches, and bridges are all networking devices that can perform a variety of functions. Within the same hardware, a router can sometimes include hubs, switches, and wireless access.
By linking devices within a building, a router can create a LAN. It also allows different networks to be linked together. A router is used to link homes and businesses to the internet. A modem is often built into the hardware of a router.
Basics of hardware and their implementation in Networking
- A modem is a device that connects a computer to the internet via a telephone line. A modem translates digital signals from a computer to analogue signals, which are then transmitted over the phone line. On the other end, a modem turns the analogue signal into a digital signal that can be understood by another computer.
- Hubs, bridges, and switches connect many devices to the router and transfer data to all other devices on the network.
- A router is a more complicated device that often incorporates hubs, bridges, and switches.
- A hub is a device that broadcasts data to all other devices on a network. This can eat up a lot of bandwidth because it sends superfluous info to all computers that don’t require it.
Use of Bridges
- A bridge is a device that connects two different LAN networks. Through the operating system, a computer can operate as a bridge. Before sending a message, a bridge checks for the receiving device. This means that if the receiving computer is not available, it will not send a message. It will check to determine if the message has already been received by the recipient. This can assist reduce needless data transfers, improving network speed.
- A switch is comparable to a hub and a bridge in function, but it is more powerful. It keeps track of network devices’ MAC addresses and filters data packets to see which ones have requested them.
More important aspects in Networking
To connect to a network wirelessly, you’ll need a wireless access point (WAP). WAPs are frequently integrated into broadband routers. A MAC address is assigned to each piece of network hardware. When a product is manufactured, this is embedded in the hardware, and the user cannot change it. A MAC address is a unique code embedded into a network interface card (NIC) on a computer. A MAC address is unique to each computer. A MAC address consists of 48 bits of data, which are often expressed as 12 hexadecimal characters.
Network interface cards (NICs) allow desktop and laptop computers to connect to a network. A network interface card (NIC) is a tiny circuit board that connects to the motherboard. A GSM chip is also used in smartphones to connect to the phone network.
