What is computer Software? And Relationship between Hardware and Software.

Source Internet
I am creating a tutorial here that I hope will be extremely helpful for you based on my learning experience doing this thing for myself. Today I am going to teach you the best of what I have learned, in more than 3 years of being a student of computer science. Today I will teach you about computer software and the relationship between hardware and software. I hope it is helpful for you… Let’s start...

As we know that we always use the terms “Software” and “Hardware” in the connection with computer and laptops. As we simply know that what is actual meaning of Hardware? If we break hardware word then it seems like Hard and Ware. You can say that the Hardware refers to the physical devices of a computer operating system. It means output devices, control, processing, input, storage are hardware.  Let’s go deep in above statements.

What is Software?

As we know that an operating system cannot do anything its own. We have to give instructions to it to make it do as we want to do a job desired. It means it necessary to specify a sequence of instructions an operating system or laptop must perform to solve a problem. Such a sequence of instruction written in a language understood by an operating system or laptop is called a computer program.

A computer program controls an operating system processing activity, and an operating system performs precisely what the program wants it to do. When our operating system has used a program to perform a task or any work, we say, it is running or executing that program.

We can say that software refers to a set of computer programs, procedures and associated documents like flower charts, manuals, etc. these all things describes the programs, and how they are to be used.

A software package is a group of programs that solve a specific problem and perform a specific type of a work and job. Let’s better understood through an example,  a word processing package may contain programs, for text formatting, for text editing, editing graphics, and drawing graphics, checking our spellings and many kinds of job etc. Simply we can say that a multipurpose computer system, a like a personal operating system. It has several software packages, one each for each type of work or job it can be performed.

RELATIONSHIP BETWEEN SOFTWARE AND HARDWARE 

As we know that hardware and software work together in an operating system. Our operating system cannot be done with hardware on its own, and software cannot be utilized without supporting hardware. Let’s go deeply to above statement.

To take an analogy, a CD player and it CDs purchased for the market are hardware. However, the songs recorded on the CDs are its software. To listen to a song, that your favorite song has to be recorded on one of the CDs first. Which is then mounted on the CD player and played. Similarly, to get a job done by an operating system, the corresponding software has to be loaded in the hardware first and then executed.

These facts about software and hardware bring out the following remember points regarding the relationship between Software and Hardware:

1. Both hardware and software are necessary for a computer to do a useful job. Both are complementary to each other.

2. We can load different software on the same hardware to make a laptop or computer perform different types of work and jobs.

3. Suppose you want to upgrades your (hard disk capacities, or adding speakers, to increasing main memory, modems etc.) hardware is normally a one-time expense, whereas software is a continuing expense. We buy new software for running on the same hardware as and when a need arises, or funds become available.

Hope above information useful for you. If you find any mistake or doubt related this article then let me know through your comment and if you like then don’t forget to share this tutorial with other computer lovers.

  2. I deleted my automobile decomp as they are debatable as you mentioned. Also be certain that you update your intake boot into the style with all the metal clamp. The plastic consumption clamps are notorious for loosening and causing an air flow which will burn the Saw down. Last, there is an noodle upgrade kit for your carburetor in case you've got the Walbro. In the event you've obtained the Zama carbohydrate I believe you're fine.
