Computer-6

Sometimes “Bridge” term is used in Computer-Networking.

Bridge is basically that device which is used to filter data between networks.

Let’s discuss about one more term called “Spooling”.

Do you know?

What it’s?

Spooling is basically buffering. We have observed it in many instances like while printing. Before printing ... we observe that there is buffering of data.

Also, note that SPOOL stands for Simultaneous Peripheral Operations On Line.

Have you been aware of “OSI model”?

OSI stands for Open Systems Interconnection Model. It basically describes how data is communicated. This description is done by describing 7 layers. Each layer has its own purpose.

Let’s not go in detail of this concept.

One more term has been used now a days called “Spoofing”.

It means to gain access of identity etc. of a network and thus causes challenge to security of the network.

Let’s go through one last concept of this lecture called “Aging”.

It simple means to increase the priority of a process which is waiting in queue. Thus, problem of blockage is avoided by “Aging”.

Please note that this blockage of processes is called “Starvation”.

Before winding up this lecture, I want to remind you not to study the concepts of Computer-Science comprehensively for your IBPS-Clerical exam because you are not going to appear for IT-Officer exam.

But superficial knowledge of variety of concepts can be helpful.
