Computer Software Essay

What Is Computer Softw be? When you think of a calculator imagine a machine made of two move. The first part is the computer ironware, the physiologic parts of the computer that you can actually touch. Some examples of computer hardware are disks, monitors, boards, chips, etc. Hardware does all of the physical work of the computer, from memory storage to display. The second part, what we call computer software, acts as the brain of the computer, singing the hardware what to do and when and how to do it.Think of a computer as a living existence in this example, the hardware would be the ody, the eyes, the limbs, the lungs, etc. Computer software would be the mind, interpreting sounds we hear with our ears into perceptible symbols. The software in our brain would tell our other body parts how to behave. Both parts are crucial for the survival of the body. Computer hardware, any single part of a larger machine, is only constantly on or off.There are no other states of being fo r the hardware, and computer hardware operates on a system called binary. Computer software uses this binary code to tell the computer hardware what to do. Computer software translates our human input (clicking a ouse or loading a disk into a drive) into a language that the computer hardware can use to actually perform a function. As such, computer software depends on hardware to survive Just as much as hardware depends on software.Where Does Computer Software Come From? Computer software is usually created by computer programmers victimization a programme language. The programmer learns a programming language that the computer can use to bidding the hardware to perform a task. The computer programmer (or software engineer) writes commands in a given programming language tha the computer understands. These languages are not otally like languages you speak, but many of them use our language in a way that makes sense to the programmer.Common commands in programming languages are thi ngs like if / then or type or function. These individual commands are called code. Another piece of software called a compiler takes the source code writen by a software engineer and translates it into the language that the computer understands. What starts as a series of translations results in activity at the software and hardware level of a computer known as a computer program. This is Just another word for software.
