Continuing our new ‘Engineers Tip’ series this week, we want to explain some of the IT terms you hear all the time.
Server – A computer or computer program which manages access to a centralised resource or service in a network. This can be based onsite or offsite and will typically host shared databases, programs and files.
Virtualisation – To create a virtual version of a device or resource such as a server, storage device, network or even an operating system. For example you could create a virtual server within your existing server without adding any additional hardware.
Router – A device that connects your network to the internet or another network. The router is responsible for moving packets of data to their next destination
