A microcode refers to the processor and machine instruction set which is at the lowest specific level. There are very small instruction sets in this particular layer. These instruction sets are basically obtained from machine language but there is a lot of difference between a microcode and a machine language. As such, machine language typically …
A server in a computer is that particular piece of hardware that offers functionality to other devices or programs called clients. It can also be a computer program or software. The functionalities offered by a server are called services which include: Sharing of resources or data among several clients and Computing for a client. Ideally, …
Programmable Read Only Memory or Programmable ROM or simply PROM refers to that particular computer chip which can be programmed after it is created, unlike a regular ROM. This permanent memory was first developed in 1956 by Wen Tsing Chow. When this chip is programmed, the information stored in it stays there forever and cannot …
What are the differences between modem and switch? It is quite challenging for a first timer or one who is not very tech savvy to understand computer networking fully given the fact that it is full of technical terminology. Add to that, the different devices used in it, such as a modem and a switch …
In the world of computers there are lots of confusing terms and all of them need not be technical jargon. Even simple words such as internet and computer network can create a lot of confusion among the unknown and to those users who are not very tech-savvy. It is very important for a user not …
A computer network indicates the group of computers that are connected together through either wired or wireless means. The main purpose of a computer network is to communicate data by using the right communication processes and networking technologies through the related communications channels. Since it deals with data transfer, it is easy to mix it …
A Printed Circuit Board, commonly known as a PCB, refers to the particular board in a computer that comes with different circuits to connect the different electronic components together that are used by the system to function. The Printed Circuit Boards are typically made from an electrically non-conductive substance such as fiberglass. These boards contain …
A printer is an output device. This external hardware produces the hard copies of the electronic data stored in your computer or any other device, if connected.
