Computer network designing takes into account different aspects and topics. An ideal computer network design will be based on layout, capacity planning, and security plans.Computer network design requires a good understanding of topologies such as a bus, ring, star, so on. Designing a network has to follow certain rules. The set of rules governing setup of a network is called its topology. Ethernet, today, is most popular topology in use. It consists of computers and peripherals cabled together in specific ways. Ethernet is relatively cheaper, easy to set up and use, and faster. There are two types of Ethernet – Standard and Fast Ethernet.
To talk of cables, you can use twisted-pair (also known as 10BaseT) or thin coax (also known as 10Base2) for your network cable. The choice, however, will depend on type of network you’re setting. You can use both types together. Twisted pair cabling is cheaper, flexible, and ideal for cabling short distances. You can use thin coax for larger networks.
A network interface card (NIC) connects network computer to network cabling. While some NICs are installed inside computer others may need PCI slots. A network adapter is needed when network is supposed to support very high speed data transfer.
The final piece you need to get through network design is a hub. It is used to gather groups of PCs together at a central location. The type of your network and data transfer support required will again decide type of hub network requires.
