Even a basic knowledge of networking is a major asset in today’s world. Even if you don’t want to get into the details of the subject, the ability to connect your computer to other computers, a router or a peripheral will save you a lot of headaches. It is also a good idea to have a basic knowledge of the equipment you need and what it does. In this article we look at the basic building blocks of a network and explain what the various pieces of hardware do. Of course, any network will need at computers. The most basic requirement of any network is that the various components are connected to each other.
Here, there are two choices. Cable or wireless. Ethernet cable remains the fastest of the two and remains an important building block of most networks, especially large business network where high data transfer speeds are essential. Although networks can exist without being connected to the , it is rare in today’s world. And for a network to connect to the internet a modem is required. Most modern home or small business networks will use a cable/ADSL modem. A router is essential for all networks as it provides the connection between the Local Area Network (LAN), which is the home or small network, and the Wide Area Network (WAN), usually the internet.
There is often a lot of confusion about the difference between switches and hubs. Both allow computers and devices within a network to communicate with each other, but there are some significant differences between them. Hardware firewall devices are not really necessary for home networks. The firewall software on your individual computers’ operating systems’ firewalls, and the security options provided by your router, should be more than enough to protect your network.
