Before getting into computer networking, it is essential to focus more precisely on the fundamental theoretical concepts.
Thus, a computer network is composed of a set of computer equipment connected to each other through different connecting elements such as cables, network cards, wireless devices, etc.. The main function of a computer network is to enable users to share the same computing resources, which are nothing other than software (programs and data) and hardware (printers, scanners, etc).
The networks can be classified according to different criteria. For example, depending on the configuration of the equipment is possible to distinguish two types of networks: client / server and as equals, with the elements of network security in each is distinct.
Network Client / Server
In a client / server network, there are two types of devices: clients and web servers. Suppose, for example, a client / server network consisting of three machines and a client server equipment, which allow sharing a scanner and a printer. The workstations are client devices that may employ a network of users to request information (data) and services (document printing, file transfer, mail server, etc) to equipment.
When a client / server network there is a great demand for resources, it is normal that there are multiple web hosting servers, each of which may be dedicated to offering a single type of service or information. Thus, a dedicated server can only be files, printers, databases, electronic mail, web pages, etc.. By general rule, the dedicated servers are much more effective than those that are assigned multiple tasks.
If a network is only one server, it will be in charge of performing all tasks of a server, so users of workstations can only access the network resources that would allow such a server.
The client / server networks are deployed in many companies and organizations and is also quite common for a student who made a computer monograph based on a particular organization, or a case study, resolve to deal with the topography of this network at your local stage. All of them have at least one network administrator, the person who is responsible for its administration. Some of the most important tasks of a network administrator are to configure it, manage users, manage their resources, ensuring security, etc...
Equal to Same Network
On the other hand, in a network as equals all equipment can be client and server at the same time, that is, there are exclusive customer equipment or dedicated servers. For example, suppose a network of four computers, and each one can be a client and / or server of the other three.
It is unusual for a network as equals there is an administrator of the entire network, but that often the user of each PC that, doing the duties of an administrator to decide which features to share and what not. Depending on the distance separating the equipment comprising a network, this can be of two types: Local Area Network or Wide Area Network.
Local Area Network and Wide Area Network
In a Local Area Network (LAN) devices are connected within walking distance. For example, all equipment in an office, a classroom or a supermarket. In all cases, the configuration of the equipment can be client / server or equal to equal.
The geographical boundary of a LAN is a few kilometers, so that could also be part of it, for example, all equipment of a university campus, a hospital or an airport. But, when the distances between the units are larger (tens, hundreds or thousands of kilometers), the network shall be called the Wide Area Network (WAN).
For example, the network equipment that connects a company that has offices in several cities or countries is a WAN. On the other hand, a WAN can also connect to two or more LANs. For example, the company that has offices in different cities; it is normal that you install a LAN in each office and inter-connect to form a WAN.
