Software is a series of instructions and details that tell a computer exactly how to perform. It is very different from physical hardware, where the system is constructed and actually does the actual work. Physical hardware is very complex and difficult to manufacture, whereas software comes as a package of instructions that operate on the computers operating system. There are a number of factors that affect the complexity of software. Some of these factors are inherent in the very nature of the computer itself.
There are two main types of software systems. These main types of software are desktop and server applications. Desktop application software refers to programs that a user uses to operate their computers. The most widely used types of desktop application software include word processing applications, spreadsheets, presentation software and web browser software.
Server application software refers to any type of software that is needed for users to run other computers. Common examples of server software include network server software and email server software. The operating system that runs on computers also determines the type of software that is installed on a computer. For example, Microsoft Windows and Apple Mac OS X both use the Microsoft Windows operating system. Apple Macintosh OS X uses the Apple Mac operating system.
Some computer software has a high level of security designed to prevent unauthorized access to information. Security software is also included with the application software. This security feature may be incorporated into the operating system, or it may be provided as an extra feature to a licensed application. Basic security features are designed to protect against hackers who may gain unauthorized access to the information stored in a computer.
Some operating systems, such as Windows, allow users to share the system software and hardware between multiple computers. This sharing may occur on a local area network (LAN), wide area network (WAN), or intranet. Wide area networks are networks that interconnect computers through telecommunication lines. Intranets, as the name suggests, are internal networks that are not connected to any other networks. Wide area networks often use a centralized data center. Internet providers use the Internet to create Wide Area Networks.
Before buying a computer system, it is important to determine what type of software is needed. Some types of computer software are proprietary, which means that the owner of the software owns the entire product. Examples of open source software are the Linux operating system and Sun’s Open Source software. Computer hardware that comes pre-installed with a computer system, called hardware that is pre-configured, is also considered proprietary software.
Most companies hire software engineers and software testers to check the quality of the software before it is released to the public. Software engineers are responsible for writing the source code, which is the language of the computer system. Software engineers need to ensure that the source code is correct and does not have any abnormalities. They must make sure that the software does not contain security or compatibility issues that could cause problems for the company if it were to be used. Software testing is usually done during the development phase, but software testing is usually performed after the software has been released to the public. The software engineer will test to make sure that the computer system functions properly.
Whether the user software includes a database, a web browser, or a text editor, the system software must function correctly in order for the computer to function properly. Users should test the application software, and its database, web browser, and a text editor. When a user finds bugs in these applications, he or she should report them so that they can be repaired. It takes time for applications to be tested, and for the bugs to be fixed, so it is important for people to know how to use these applications and to learn to fix bugs if they find one.
