A simple definition of network is a series of points that are connected to create communication between other computers and devices. They may be connected by network cables or by a wireless signal. Depending on how far these networks extend, they are labelled a LAN, MAN, or WAN network.
LAN: (local area network) A group of computers that share a common connection and are usually in a small area. For example an office or home network.
MAN: (metropolitan area network) This is a larger network that connects computer users in a particular geographic area or region. For example a large university may have a network so large that it may be classified as a MAN.
It is far larger than a LAN and smaller than a WAN. Also large cities like London and Sydney, Australia have metropolitan area networks.
WAN: (wide area network) This is the largest network and can interconnect networks throughout the world.
Having a computer network was previously reserved for a professional setup usually in a corporate or business workplace. However now days even the average everyday household with a mere two computers has most certainly networked them in order to share files and an internet connection. This is why we all will find these networking tips and definitions a valuable tool.
