"Software" redirects here. For other uses, see Software (disambiguation).
Computer software, or just software, is a collection of computer programs and related data that provide the instructions for telling a computer what to do and how to do it. In other words, software is a conceptual entity which is a set of computer programs, procedures, and associated documentation concerned with the operation of a data processing system. We can also say software refers to one or more computer programs and data held in the storage of the computer for some purposes. In other words software is a set of programs, procedures, algorithms and its documentation. Program software performs the function of the program it implements, either by directly providing instructions to the computer hardware or by serving as input to another piece of software. The term was coined to contrast to the old term hardware (meaning physical devices). In contrast to hardware, software is intangible, meaning it "cannot be touched".[1] Software is also sometimes used in a more narrow sense, meaning application software only. Sometimes the term includes data that has not traditionally been associated with computers, such as film, tapes, and records.[2]
Examples of computer software include: * Application software includes end-user applications of computers such as word processors or video games, and ERP software for groups of users. * Middleware controls and co-ordinates distributed systems. * Programming languages define the syntax and semantics of computer programs. For example, many mature banking applications were written in the COBOL language, originally invented in 1959. Newer applications are often written in more modern programming languages. * System software includes operating systems, which…...

...verdict. Sincerely yours, (Syed Shohan Shah) On the behalf of the group EXECUTIVE SUMMARY In this modern age computer is a very essential in our everyday life. It helps our every work. Without computer we can not live without a single day. It has many parts like hardware which are touchable and software which are untouchable. Computer users may use a scoring system of evaluation when there are several competing proposals for a hardware or software acquisition. They give each evaluation factor a certain number of maximum possible points. Then they assign each competing proposal points for each factor, depending on how well it meets the specifications of the computer user. Scoring each evaluation factor for several proposals helps organize and document the evaluation process. It also spotlights the strengths and weaknesses of each proposal. Computer Hardware 1.0 Monitor Multiple technologies have been used for computer monitors. Until the 21st century most used cathode ray tubes but they have largely been superseded by LCD monitors. Cathode Ray Tube The first computer monitors used cathode ray tubes (CRT). Until the early 1980s, they were known as video display terminals and were physically attached to the computer and keyboard. The monitors were monochrome, flickered and the image quality was poor. In 1981, IBM introduced the Colour Graphics Adapter, which......

Computer-Aided Software Development Process Design

...field of IT, more precisely Computer Software Development which is the process of writing and coding a software or application for a business or corporation. I chose to do some research on new topics and methods introduced to successfully finish a software project. Here is the outcome of my research on the “Computer-Aided Software Development Process Design”. To begin, the software development process faces many problems such as; the project manager providing insufficient time and resources, changes in the customers’ requirements for the software, and lower than expected productivity by the project staff. The objective is to develop a computerized intelligent tool that project managers can use in effective planning and management of the development process. This tool will provide day-to-day updates on the actual data generated for the project. Dr. Yau and Dr.Tsai presented this as an approach to facilitate the validity and integrity checking of the interconnection among software components during software development or modification. Afterwards, Dr. Matsumura proposed the CASDS, or computer-aided software design system, which uses three structural modeling methods to determine a software design from software requirements. Another system was introduced later in the article by Horowitz and Williamson, named SODOS, which supports the manipulation of documents used in developing software. This system permits traceability through all phases of the software life. I found this......

Importance of Securing Data and Software More Than Computer Hardware in an Organization

...IMPORTANCE OF SECURING DATA AND SOFTWARE MORE THAN COMPUTER HARDWARE IN AN ORGANIZATION BY DHUMISAN CHISI SUBMITTED TO MR MWEKHELA IN PARTIAL FULFILLMENT FOR THE COURSE FUNDAMENTALS OF INFORMATION SYSTEMS COURSE CODE CCC1073 THE MALAWI ASSEMBLIES OF GOD UNIVERSITY 23TH MARCH 2015 Information systems have long been at some risk from malicious actions or unplanned user errors and from natural and man-made disasters. In recent years, systems have become more at risk to these threats because computers have become more organized and, thus, more interdependent and accessible to a larger number of individuals. In addition, the number of individuals with computer skills is increasing, and intrusion, or “hacking,” techniques are becoming more widely known via the Internet and other media. In large organizations computers are kept in large scales and also store a lot of important data and information plus maybe softwares of the at most important. These softwares and information require to be kept safe and protected. It is the sole purpose of this paper to explain the reasons why it is important to secure the organizations data/information and computer softwares of an organization. Some of the information used in business organization requires special protection for confidentiality (to ensure that only those who need access to that information to do their jobs actually have access to it). Some of the information used in business organizations need......

D1 – Explain How Software Utilities Can Improve the Performance of Computer Systems.

...D1 – Explain how software utilities can improve the performance of computer systems. Software utility | How can it improve computer performance? | Improvements that can be made to the utility | Anti-virus | When viruses enter a computer the performance will significantly decrease because the viruses take over all the system files and change their information. Antiviruses help improve the performance because they stop the viruses from coming in the computer before they make the computer slow as antiviruses scan in real time and whenever a file is downloaded it is always scanned. | Anti-viruses should be constantly searching for new viruses being made and should have constant updates where it will always remove the viruses and stop them from entering your computer. Instead of having scheduled updates they should be constant so new viruses can be detected. There should also be constant virus scans which do not slow the PC down. | Firewalls | Firewalls help improve computer performance because it stops connections from outside of the local area network coming in through ports and controlling the PC or taking files with important credentials stored on it. It is basically a barrier to keep unauthorised elements out of a network or a computer. They are filters for your traffic incoming to your computer so it can block incoming packets that are unsafe. | Firewalls can only protect what they can. It is impossible to stop every single virus that a software might have coming into......

Software Engineering for Computer Games

...LITERATURE REVIEW ON SOFTWARE ENGINEERING FOR COMPUTER GAMES Name: Course: Date Page 1 Abstract Games have often been very common in the past period of time, but with the discovery of computer games, they have penetrated. In spite of the third vista to computer games which is verifiable, it pertains to investigating what characteristics those who play such games anticipate from the gaming using the computer. Permit us state the meaning of a computer game as a play which is undertaken with an aid of a computer program. This meaning still leaves behind some flexibility because it does not imply that the whole game happens in the computer. For instance, Chess may be played on the computer screen and on a true-globe board, heedless to whether the one who objects to the play is a computer application. Huizinga in his classic work defined play as ``an activity which proceeds within certain limits of time and space, in a visible order, according to rules freely accepted, and outside the sphere of necessity or material utility. The play mood is one of rapture and enthusiasm, and is sacred or festive in accordance with the occasion. A feeling of exaltation and tension accompanies the action, mirth and relaxation follow``. A lexicon likewise states the meaning of game as `‘a universal form of recreation generally including any activity engaged in for diversion or amusement and often establishing a situation that involves a contest or rivalry’`. Besides,......

Study Pn Evolution of Computer Software

...EVOLUTION OF COMPUTERS STUDY ON EVOLUTION OF SOFTWARE Introduction Computer software, or just software, is any set of machine-readable instructions that directs a computer's processor to perform specific operations. The term is used to contrast with computer hardware; the physical objects carry out the instructions. Hardware and software require each other and neither has any value without the other. The first theory about software was proposed by Alan Turing in his 1935 essay Computable numbers with an application to the Entscheidungsproblem (decision problem). Colloquially, the term is often used to mean application software. In computer science and software engineering, software is all information processed by computer system, programs and data. The academic fields studying software are computer science and software engineering. The types of software include web pages developed in languages and frameworks like PHP, Perl, JSP or ASP.NET and desktop applications like OpenOffice.org, Microsoft Word developed in languages like C, C++, Objective-C, Java, C#, or Smalltalk. Application software usually runs on underlying software operating systems such as Linux or Microsoft Windows. Software (or firmware) is also used in video games and for the configurable parts of the logic systems of automobiles, televisions, and other consumer electronics. Software evolution is the term used in software engineering (specifically software......

Copyright Protection for Computer Software

...been the primary means for protecting utilitarian works. Computer software as a relatively new recipient of copyright protection, however, defies easy categorisation within the traditional framework of the intellectual property system. 1 With respect to computer software, courts have had to grapple with the vexatious issue of drawing a precise line between copyrightable expression of computer software and the uncopyrightable processes that they implement. The present paper seeks to study some of these themes and the principles enunciated in judicial decisions in clarifying the issue. Computer software as literary work It is a well-established proposition that computer programs2 are copyrightable subject-matter, just like any other literary work.3 Loading a program into computer memory, saving the program or running it without authority may infringe copyright. Making an arrangement or altered version of the program or converting it into or out of one computer language or code into a different computer language or code is also an infringement.
