The need to easily share data, controlling security, and easily manage all the devices on a network are all common among every one of today’s modern business. The best way to meet all of these needs is a server. What is the purpose of a server, you might ask. “Servers perform functions ranging from file storage and managing printers to offering database services. Large companies often maintain individual servers dedicated to one task, such as email,” – Houston Chronicle. A server is a system that runs software designed to accomplish all of these tasks, and more. Sometimes a server will run programs that all the workstations on a network will log into and access. Simply stated, a server is the hub in a business’ day-to-day operations.
In our last article, The Ping: How Does a Network Work?, we explained that a network “….allows all your devices to communicate and share data/resources with each other, either wirelessly or wired in a secure environment.” A Switch is the core of this environment. Switches allow the computers on your network to talk directly to one another. What if you want your computer to get to the internet or another network? You need a router for this. A router “routes” data from within your network to and from outside networks like the internet. If you’ve never heard of a router you’re not alone. Most small to medium sized businesses do not use plain old routers any more. Instead they use the routers more sophisticated cousin, the Firewall, to do the same job.
