what is networking and how it works?

Computers that connect to a network are generally categorized as servers or workstations. Servers are generally not used directly by humans, but continue to operate to provide “services” to other computers (and human users) on the network. Services offered may include printing and faxing, software hosting, file storage and sharing, messaging, data storage and retrieval, complete access control (security) to network resources, and more.

 

Workstations are called such because they usually have human users communicating with the network. Workstations are typically considered desktops that include a computer, keyboard, screen, and mouse, or laptops with an internal keyboard, screen, and touchpad. With the advent of tablets and touch screens on devices such as the iPad and iPhone, the definition of a workstation will evolve rapidly and include these devices because of their ability to interact with networks and use network services.

Servers are usually more powerful than workstations, although configuration is based on needs. For example, a group of servers can be located in a safe area, away from him, and could only be accessed through the network. In such cases, it would be normal for the server to run without a special display or keyboard. However, the size and speed of a server processor, hard disk space, and main memory can dramatically increase system costs. On the other hand, a workstation may not require usable storage space or memory, but it may require an expensive screen for the user’s needs. Every computer on the network must be properly configured to use it.

 

In a single LAN, computers and servers can be connected wired or wirelessly. A wireless access point (WAP) provides wireless access to a wired network. These WAP devices provide a bridge between a computer and a network. Typical WAP may have the theoretical capacity to connect hundreds or even thousands of wireless users to a network, although the practical capacity may be less.

 

Cable servers almost always connect to the network because cable connections remain the fastest. Workstations (desktops) are typically installed on a network, although the cost of a wireless interface goes down to make it easier and cheaper to use a wireless desktop connection when installing a workstation in an existing facility with inadequate wiring.
