What is the Definition of Computer Software?

The term “software” is not a recently conceived of word. In his 1935 essay, ‘Computable Numbers with an Application to the Entscheidungs Problem,’ Alan Turing first proposed and provided the foundation for most modern software. In 1958, the first use of the term software was used by John W. Tukey in an article in American Mathematical Monthly.

Today, the the term ‘computer software’ means written programs, rules, or codes, along with related documentation regarding the operation of a computer system that is stored in read/write memory. The “soft” part of software refers to the many products and technologies developed using different methods such as programming languages and scripting languages. The term ‘software’ is broader and can include different types of devices such as the operation systems of modern consumer devices such as automobiles, televisions, toasters, etc.

Computer software is the job descriptions of what a computer can perform. It cannot be physically touched. For instance, most computers come with software already installed. Software is also available on CD where the user inserts the disk into the hard drive and follows the installation instructions. As well, downloadable software is available on internet sites such as Microsoft. Computer software is basically a series of instructions that tells a computer how to do a particular job. For example, Microsoft Word is an example of computer software. As well, web page technologies such as HTML, PHP, ASP.NET, and XML are examples of computer software.

Computer software can be divided into two main categories: operating system software and application software.

Operating System (0/S): This system consists of the basic functions that computers perform. An example would be showing movement on a screen such as a mouse cursor was the user moves the mouse. Examples of operating systems include: windows vista, windows xp, Mac, Linux and Unix.

Application Software: These are applications that allow the computer to perform the job. Application software is used to accomplish precise tasks other than just running the computer system. This can include voice, play or record music, view videos, play video games–etc. Other examples of application software include permitting access to the internet and printing documents. Application software is the software that indirectly interacts with the computer.

System Software is the software that can directly interact with computer hardware. Examples include motherboard, CPU, keyboard, Mouse, printer–etc. System software is responsible for controlling, integrating, and managing the individual hardware components of a computer system.

Computer software is composed of machine language which is essentially groups of binary code giving processor instructions that are specific to an individual processor. It is normally written in high-level programming languages and then interpreted into machine language code. Software can also be written in assembly language which is a mnemonic representation of a machine language using a natural language alphabet.

The term computer software evolved from computational theories and formulas from pioneers in mathematics. It is easy to see how quickly technology evolved to the amazing and complex computations we see today.

Improve Computer Performance – 7 Lightning Quick Fixes

If you have a Windows-based machine, you may have noticed a decline in your computer’s performance since you bought it. It may freeze up suddenly, or it just could be acting a bit sluggish. Instead of buying a new system, you should first try whatever you can to preserve your current one. Here are 7 lightning quick fixes to improve your computer’s performance.

Solution #1: Run anti-virus software: Computer viruses are especially frustrating because in most cases they are made by someone with nothing better to do than to try to hurt your computer. Viruses can slow performance or even wipe out precious data. Avoid this fate at all costs by buying a good anti-virus software solution and running it all of the time. To find one, do a Web search and compare options.

Solution #2: Run a defragment routine: Okay, this sounds esoteric and technical but it is actually bone simple to do. All this means is that you are arranging the data on your hard drive more efficiently. Do a search on your operating system for defragment and follow the prompts. This fix is free but can take an hour or more to run, so plan accordingly.

Solution #3: Clean up your hard drive: Here is another super-easy and free fix and involves ridding yourself of unneeded files on your hard drive. A less cluttered hard drive usually results in better performance. Do a search for disk cleanup and follow the prompts.

Solution #4: Clean your registry: Your computer has something called a registry that stores important information about the users and applications that access your computer. As time goes by, registries become rife with errors. To find one, run a Web search for a registry cleaner. Most of them cost about , but they work great and are well worth the investment.

Solution #5: Run anti-spyware software: Like a computer virus, spyware is also a pretty nasty little monster. It sits on your computer and watches your every move, sometimes even sending information about your activity to other computers. Not a pretty picture, and it can slow down your performance as well. To disable your spyware (you likely have many), find any of a number of the excellent for-pay or free anti-spyware programs available on the Internet. I suggest running at least two. There is no harm in this and you will definitely find and fix more problems than if you just use one.

Solution #6: Buy more memory: Computer memory, or RAM, is like a temporary workspace that your computer uses for almost everything it does. If the workspace gets cluttered or full, the ability for your computer to take on additional work is hampered. With most applications these days requiring more and more memory, getting an additional 1GB or so of RAM is a very good investment and a great alternative to the cost of upgrading your machine.

Solution #7: Clean your hard drive more thoroughly:

Your hard drive is the core of your machine, shuttling data back and forth between permanent storage and working memory (RAM). To keep it in tip-top shape, run a third-party hard drive cleaning application. CCleaner is great and is available for free on the Internet. There are other good products available as well. Running this should take about 5 minutes and your computer’s performance should show measurable improvement afterward.

Most of these solutions will only take you a few minutes to implement and all are free or very cheap. So, if your computer has been acting up or just acting sluggish, give them all a try before shelling out the big bucks for a new one. Your wallet will thank you.
