But the network equipment with higher technical specifications comes at a higher cost.įor companies that plan to grow, it is highly recommended to use a topology that is flexible and can be easily expanded. Ideally, you would want your network devices to be able to handle not just your current but also your future traffic volumes. While in some other types such as the ring topology, when the network is large you may require repeaters to strengthen the data transmission. In certain types of network topology, the network performance and overall bandwidth are limited by the technical specifications of the central hub. But the better performance comes at a higher cost. Fiber-optic cables have better performance than twisted pair cables, which in turn is better than coaxial cables. The type of cable you need will depend on your network performance requirements as well as the transmission distance. So be careful to not underestimate the cost of labor needed for cabling. The cost of the cable itself will be small, but you will be surprised at how much the cost of labor involved in laying, connecting, and configuring the cables amounts to. The more network cable is required to build your network, the more labor-intensive it will be. We’ve talked about them at greater length in the following blog posts: This is just a brief introduction to these network components. together into your network.Ī firewall is a network security system, which monitors and controls incoming and outgoing network traffic.Ī bridge is a network device that connects and filters the traffic between two network segments. In other words, a switch ties the various devices such as PCs, printers, servers, etc. It forwards the packets of data between networks by processing the routing information included in those packets.Ī modem, short for modulator-demodulator, is a network device that helps your computer and other devices to connect with the internet.Ī switch is a network device that allows other devices on the network to communicate and share information. Routers are the network devices that transfer packets of data between networks. A Hub is just a repeater with multiple ports. It receives weak or corrupt Wi-Fi signals and regenerates it to the original strength. The NIC, thus, provides the computer with the capability to access the transmission media and to process the data flowing through the network.Ī repeater is a network device, which regenerates the Wi-Fi signal over the same network. Along with the required circuitry, the NIC usually has a connector to receive the ethernet cable or an antenna for wireless communication. It’s only a piece of hardware inside your computer called the network interface controller (NIC) that performs this function. When you connect your computer to a network or depict a computer as a network node, it isn’t the computer that functions as a node.
