Graphical user interface (GUI) is likely to be one of the most significant features of technology. According to (Arora et al 2005; Marcus, 1997; Barker & Lamont 1994), GUI is symbols, formats, images, games, labels and menus appear on screens which are used to reduce the system errors, improve its performance to be more appropriate for users, avoid the complex procedures and accomplish their aims of applications accurately. GUI also means how the system can make an environment to let users able
occurs mainly through digital means and media, the way information is arranged and presented on the screen is crucial. Because of this need for fast access and easy arrangement arose, in the early 1980s, companies started to work on various graphical user interfaces (or GUI for short). Most dictionaries define a GUI as ‘a way of arranging information on a computer screen that is easy to understand and use because it uses icons, menus and a mouse rather than only text.’ Introducing such software allowed
various graphical user interface features ----------------------------------- Windows is a software from Microsoft, a American based company Chairman of which is Mr Bill Gates a world known personality. He developed this software in the year 1968 which was a technological breakthrough. windows is used in more than 90% of computer users. Windows made Mr. Bill Gates the worlds richest personality Windows can be customized in appearance and colours Windows can be upgraded according to the user convenience
(OS) is a software program that manages the hardware and software resources of a computer. The operating system is an essential component of the system software in a computer system. The operating system programs make system resources available to user(s), the user’s application programs and to other application programs running on the computer. (From Silberschatz and Gagne et al., 2010) Some operating systems are designed to be convenient, others to be efficient and some combination of the two (From
to $10,000 it was the computer that combined a graphical user interface with a mouse. It had all of the same ingredients to be just has successful has the Apple II except it was not affordable. Therefore, many people started buying IBM's PCs instead. After learning a valuable lesson Apple released the Macintosh in 1984 with a price tag of $2,495, which had all the attributes has the Lisa but it was affordable and still offered a graphical user interface. The Macintosh Portable was another failure
language to allow the operating system to be completed. Through this evolution the kernel and associated software were extended until a complete operating system was written on top of the kernel in the language C. UNIX APPLICATION PROGRAMMING INTERFACE Many proprietary operating systems have a simplified view of application behavior. The typical application reads some data from disk, tape or a terminal and does some processing. Output is produced onto disk, tape, tape, terminal, or printer
Characteristics of an Operating System: Multi-User: A Multi-User is two or more users that have individual accounts that allow them to work with programs and peripheral devices at the same time. Multitasking: Multitasking is when a computer is able to run more than one application at the same time, for example have Microsoft Word and Internet open at the same time. Multiprocessing: Multiprocessing is when an Operating System can support multiple Computer Processing Units (CPU’s) Multithreading:
results once again freely distributed. The continuing growth of the Internet and the proliferation of computers that aren't standard desktop or laptop machines means that operating systems will change to keep pace, but the core management and interface functions will continue, even as they evolve.
What makes Windows so popular? Some say it is so user friendly. What exactly makes it so user friendly? An answer to that question could be that is has an incredible desktop environment with which almost any user can sit down and interact. More choices are available because, Linux is coming into the arena with some desktop environments that are just as user friendly as Windows. These will offer as much versatility if not more to allow for some great customization and installation of separate applications
acceptance. One of the technological problems that mice had to overcome was the fact that most computers and programs did not support the use of the mouse. Another problem that confronted mice is that they were most useful under a GUI (Graphical User Interface) operating system. At the time few existed on the market. Lack of funding was the main reason the mouse's existence was in jeopardy. While working on the preliminary research and development of the mouse, Engelbart discovered that they
Unlike application programs, however, system software is not meant to be run by the end user. For example, while you might use your Web browser every day, you probably have nothing to make much use of an assembler program (unless, of course, you are a computer programmer). Since the system software runs at the most basic level of your computer, it is called "low-level" software. It generates the user interface and allows the operating system to interact with the hardware. Fortunately, you don 't have
Expanded Definition of Operating Systems An operating system (OS) is an essential software that manages a computer. It acts as an interface between the computer and the user such that the computer 's hardware and software communicate effectively so as a computer or mobile device can operate properly. If a computer does not have an operating system, it is useless (Denning & Peter 31). The other programs that facilitate a computer to work more efficiently and effectively are known as application programs
Microsoft Windows is a graphical operating system, produced by Microsoft Corporation. System began operating as a front graphical MS -DOS in 1985, in a move to respond to the growing interest in the graphical user interfaces. The Microsoft Windows dominates the PC market in the world where reach share of nearly 90 % of the market ahead of the Mac OS, which was released in 1984. In this essay I will took about windows 7, window8, and the difference between windows7 and windows 8. Windows 7 is a series
idea is that one server or a number of servers run the application software that the business user connects to. The physical desktop does not run the application itself as it resides on the server. Windows and Linux are but two of the many companies that offer virtual desktop programs and applications. The applications run the gamut of user interfaces that range from state-of-the-art graphical interfaces that can be switched between multiple monitors to basic no-frills word processing functions

The History of Computers To those of us that have grown up during the computer age, computers seem like a normal part of our everyday lives. The idea that only a few decades ago computers were virtually unheard of is inconceivable. Computers are now so essential that they basically run our society and the whole of the modern world. They track hurricanes, forecast the weather, predict natural disasters, control satellites and missiles and keep countries around the world in constant contact
DEVELOPMENT OF COMPUTERS The first generation of computer which is from the year 1945 has been relatively large in size and very expensive due to the technology that we have back then. Goes by the name “Colossus”, it was the very first electronic computer developed. It is programmable, digital, electronic, computing devices. The vacuum tubes or known as thermionic valves is used to perform calculations. It serve as purpose to solve mathematic problem faced by the British military during World War

the price for each vendor, specifications, performance, and reliability. The three vendors I would like to discuss are Arch Linux, Red Hat Enterprise, and Ubuntu. Linux is an operating system that has several distros to choose from. Linux allows the user more control of the system and greater flexibility. As an open operating system, Linux is developed collaboratively, meaning no one company is solely responsible for its development or ongoing support. Companies participating in the Linux economy share
As a computer administrator one must be aware of what the system requirements are for the operating system being used or installed on a system. Computer administrators that install operating systems on new or old hardware often will research what the manufacturer suggests for the operating system to work properly. The requirements for an operating system can be broken down into two categories hardware requirements and software requirements. Hardware Requirements are the resources that are needed
