Computer Science Computer Science is the systematic study of computation with respect to computer systems and software applications. Computer science, or CS, entails both the theory of computation and algorithms used in software applications as well as the design of hardware used in computing devices like PCs, laptop computers, tablets and smartphones. From coding advanced… Continue reading

 How do you construct an increment statement or decrement statement in C? There are actually two ways you can do this. One is to use the increment operator ++ and decrement operator –. For example, the statement “x++” means to increment the value of x by 1. Likewise, the statement “x –” means to decrement… Continue reading

A memory is just like a human brain. It is used to store data and instructions. Computer memory is the storage space in the computer, where data is to be processed and instructions required for processing are stored. The memory is divided into large number of small parts called cells. Each location or cell has… Continue reading

Computer memory is any physical device capable of storing information temporarily or permanently. For example, Random Access Memory (RAM), is a volatile memory that stores information on an integrated circuit used by the operating system,software, and hardware. What does computer memory look like? Below is an example picture of a 512 MB DIMM computer memory module. This memory module connects to thememory… Continue reading

When we type some letters or words, the computer translates them in numbers as computers can understand only numbers. A computer can understand the positional number system where there are only a few symbols called digits and these symbols represent different values depending on the position they occupy in the number. The value of each… Continue reading

An arithmetic-logic unit (ALU) is the part of a computer processor(CPU) that carries out arithmetic and logic operations on theoperands in computer instructionwords. In some processors, the ALU is divided into two units, an arithmetic unit (AU) and a logic unit (LU). Some processors contain more than one AU – for example, one for fixed-pointoperations and another forfloating-point operations.… Continue reading

Introduction So you’re shopping for a new computer in an electronics store and you’re trying to make sense of the technical specifications. One computer that looks pretty cool has a 64-bit quad-core Intel i7 3.5 GHz processor. Sounds impressive, but what does it really mean? The last computer you bought a few years ago had… Continue reading

An output device is any peripheral that receives data from a computer, usually for display, projection, or physical reproduction. For example, the image shows an inkjet printer, an output device that can make a hard copy of any information shown on your monitor, which is another example of an output device. Monitors and printers are… Continue reading
