Servers (Tasks in a LAN)

A server in a network acts like the CPU in a personal computer. It maintains the traffic in the network. There are ports coming into the server and ports going out of a server much like the input and output ports in a CPU. These input ports and output ports come from other devices (in case of a server most of these devices have computational abilities). These devices use those ports to request and transmit data. As is common in the architecture of most ports, some pins exist for the purpose of requesting data, some for accessing data, and some pass control signals and acknowledgements between the various devices at both the ends of the port. Control signals and acknowledgements are important signals which are needed to effectively manage and synchronize the communication in the network.

Servers monitor the flow of devices from it and to it as well. It controls the aspects of security and firewall management of the entire network as well. Servers identify devices on the basis of their Internet protocol addresses which are individual numbers allotted to each device which access the network. The servers are generally used to store a lot of files and other data which can be accessed by the other devices in the network when needed by them. The servers can also access other computers in the network if the recipient’s firewall setting allows it to do so. This access can be used for controlling purposes or data accessing and transferring purposes as well.
