There are two basic types of LAN:
Peer to Peer (Workgroup)
Server/Client (Domain)
1. Peer to Peer (Workgroup)
(For example: a country without any Leader: means everyones is a leader and everyone has equal power. People will do whatever they like good or bad. In the same way, On a peer-to-peer network, every computer is equal and can communicate with any other computer on the network to which it has been granted access rights. )
Peer-to-peer networks are more common in small offices (LAN) or within a single department.
The advantage of a peer-to-peer (Workgroup) network is that we don't have to dedicate a computer to function as a file server. Instead, every computer can share its resources with any other.
Disadvantage of a peer-to-peer (Workgroup) network is that it has less security and less control because there is no centralization.
2. Server/Client (Domain)
(For example:a country with a king/Leader: means he will will control the whole country, people and everything. In the same way, On a Domain network, One computer will be used as server.
A server computer typically has faster processors, more memory, and more storage space than a client because it might have to service hundreds of users at the same time. A server is designed to share its resources among the client computers on the network.
Who are clients?
- Clients are the user computer that receive/send through server computer.
- A client system is a standard computer that is running an operating system such as WindowsXP, Windows VISTA, Windows Seven. These versions of Windows contain the client software that enables the client computers to access the resources that servers share.
To make a server computer we require a Server operating system such as Windows Server 2000, 2003 or Windows Server 2008.
Typically, servers are located in secured areas, such as locked closets or server rooms. The rest of the computers on the network function as clients and are used to access resources located on servers.
The main advantage of a Domain network is that it provides higher levels of security and more centralized control over client computers.
