Computer Software Defined. Computer software is programming code executed on a computer processor. The code can be machine-level code, or code written for an operating system. An operating system is software intended to provide a predictable and dependable layer for other programmers to build other software on, which are known as applications. Operating systems can be found on all smartphones, tablets, and desktop computers. These systems give the device the functionality it needs. For example, Apple's i. OS and Android's OS were developed specifically for portable devices.

Basic Examples. BIOS, in full Basic Input/Output System, computer program that is typically stored in EPROM and used by the CPU to perform start-up procedures when the computer is turned on.

Its two major procedures are determining what peripheral devices (keyboard, mouse, disk drives, printers, video cards, etc.) are available and loading the operating system (OS) into main memory.

computer programdetailed plan or procedure for solving a problem with a computer; more specifically, an unambiguous, ordered sequence of computational instructions necessary to achieve such a solution. Programs stored in the memory of a computer enable the computer to perform a variety of tasks in sequence or even intermittently. The idea of an internally stored program was introduced in the late 1940s by the Hungarian-born mathematician John von Neumann. The first digital computer designed with internal programming capacity was the “Baby,” constructed at Manchester in 1948.

Top 5 free PC programs everyone should have1 Antivirus and malware protection. Most PC users realize that they need protection on their computer or may have already have an antivirus program installed. What most don't realize is there are free programs that are as good and in some cases better than the commercial products. Below are our recommendations.

2 Backup solutions. Several free and commercially available backup programs are available for computers. Unfortunately, many of those backups are stored locally, meaning if your house got destroyed or robbed, or if you lost your backup discs, all your data would be lost. To avoid loss of important data, we suggest using online backup services.

3 Browsers. Although Microsoft Internet Explorer or Edge comes pre-installed on Windows computers, there are many excellent free alternatives that everyone should try. These free alternatives can often be faster, have more options, and in many cases be more secure than Internet Explorer.

4 Compression utility. When downloading files on the Internet, you eventually encounter a .zip, .rar, or another compressed file. Dealing with these files can be easy using a free file compression utility.

5 E-mail. E-mail is yet another service that can be done freely. Most users today use online e-mail solutions like the one listed below. However, for those still using an e-mail client such as Microsoft Outlook we strongly suggest one or both of the below suggestions.
