A computer network setup is an integral part of every organization today. The linkage of the different computers in the office space helps in the growth of the business by saving time and money. It speeds up the work pace and invariably saves a lot of time. Each office would have its own specific needs.

DHCP (Dynamic Host Configuration Protocol) is a network protocol based on the client-server model that provides automatic allocation of IP addresses and other parameters that are required to connect to the internet such as gateway addresses, subnet masks and DNS server addresses. A DHCP server must ensure that all IP addresses that it allocates are unique - that is to say that no one else is currently using them.

Unlike the ISO/OSI reference model, TCP/IP architecture is only divided into 4 layers. The exchange of information between the layers is again exactly defined and again, each service uses the services of a lower level and provides its services to a higher layer.

When a single server serves pages for many websites, each with its own domain name then this type of hosting is known as shared hosting.
