You need a set of networking equipment when setting up a computer network for your home or office. These pieces of equipment allow data transmission to happen across your computer network, and you need to understand what they comprise of to build a strong network. In this post, we’ll take a look at various equipment that you need to create a network and connect it to the Internet.
Different Computer Networking Equipment
There are several types of computer networking equipment that you need to be familiar with. Below are some networking equipment and how they contribute as a whole to the overall functioning of a network system.
Hub is a device that connects multiple devices in a single LAN network. Hubs do not filter data, but instead, retransmit incoming data packets to all parts. When a computer requests information from a specific computer or a network, it sends the request to the hub through a cable. When a hub receives signals from a connected device on any of its port, it transmits those signals to all other connected computer from the remaining ports. Each computer in the network will then check whether the broadcast data is for them or not.
A repeater is an electronic device that regenerates the signal over the same network before the signal becomes corrupted or weak. Keep in mind that repeaters do not amplify the signal. They copy the signal bit by bit and regenerate it at the original strength when the signal becomes weak.
A bridge is a piece of computer-networking equipment that connects two separate LAN networks. A bridge search for the receiving computer before it sends data, which means it will not send data if the receiving device is not available. Bridges also check to see if the receiver has already had the data; this can help save unnecessary data transfers, which increases the performance of a network.
A modem is a device people use to connect with the Internet. The word “modem” is a mix of two terms, “modulate” and “demodulate,” which are the main operations performed. A modem converts digital signals into analog signals sent over the analog medium and then decoded these signals back into its digital form at the receiving end. Modems come in different types depending on your service. For example, a cable modem uses a coaxial link while a DSL modem connects to your ISP via a telephone line.
A router is an essential part of any computer network. It’s responsible for routing data packets based on their IP addresses. Routers are your first point of defense and can be configured to pass only traffic that your network administrators authorize. When the device receives a data packet, it checks the destination address of that packet and forwards that data from the interface, which is connected to the destination address.
Network firewalls safeguard a network against unauthorized access or attack. Firewalls can be software or hardware. They permit or deny access to private network devices and applications. A firewall allows users to access any of the resources they need when properly configured while keeping out unwanted users, hackers, worms, viruses, or other malicious programs trying to gain access to your network. It’s best to use both software or hardware firewalls for optimal protection.
7. Wireless Access Points (WAP)
A wireless access point allows users to connect Laptops, Tablets and other mobile devices to the network. Unlink consumer wireless routers, WAP’s allow you to use a centralized management interface to manage multiple wireless access points at once. This also allows you to implement VLANs (Virtual Local Area Networks) to secure your business Wifi.
These collections of networking equipment remain constant, and at least two or three of the above can be found in most networks. So whatever computer you are using or wherever you are, you can rely on networking equipment to bring the world to your fingertips.
