Every machine operating on the web falls in one of two categories. It can be a server, which would mean that it is a device that allows other devices to connect to it in order to carry out various operations like browsing a website. Or, it can be a client, which is a device that connects to a server in order to access a service enabling it to carry out an operation. It is possible that a machine acts as both a client as well as a server, but mostly, it performs just one of the two roles.
Servers are usually configured to perform a specific kind of function, but they can perform several different functions as well. This means that depending on the kind of request that is raised by the client device, it will access a specific area of the server that is set up to cater to those kinds of requests. A console server becomes a good choice in this situation due to its flexibility and serial port management functionality.
Console servers are bigger machines than the client devices and are configured as per the requirements of the users. They usually facilitate remotes access from several client devices at the same time. A lot of importance is given to data security in case of console servers. Only authorized personnel are allowed to access specific areas of the server and the data that transmits through it is encrypted. An understanding of the client server environment and their interaction with each other can help a lot in clearly defining your specific needs.
