Recommended: The basic features of graphical user interface
Three types of user interfaces are command driven, interface menu driven, and interface graphical user interface. A command line interface is basically just a plain screen, usually white text on a black background, such as MS-DOS or the Command Prompt in Windows, where a user can type in commands into the input. As an overall statement, a CLI requires that the user know their material in order for it to be effective. The CLI offers users enormous elasticity in that a single command can be executed with a range of arguments, but the effectiveness is in direct proportion to how many commands and arguments for a command that the user is aware of. Also, the CLI can sporadically present certain actions that are completely unavailable in a GUI. For instance, the DOS command "ren *.txt *.bak" will change the extension of all .TXT files to .BAK, while leaving the filename intact. A batch rename of this type is not possible through the GUI. Lastly, CLI commands and arguments can be used to create scripts, such as a bash shell script or a DOS batch file. If the user knows the exact commands necessary to perform an action, this scripted series of events can be kept to a single executable text file.
The advantages of CLI are that they allow you control every aspect of your computer. Once it is learned properly it is fast. It allows you to do things at different times, such as setting a time for a download script. Everything is located in a central location. CLI is also good for speed if you have a slower computer. Some of the disadvantages of CLI are that is a lot of information to learn, it is not a graphical user interface. Many of the advantages of the interface are mainly for Linux and now for windows.

...uch more visually instinctive, new users almost always pick up this interface faster than a CLI. Still the most efficient in my opinion would be the CLI. Command line users only need to use their keyboards to navigate the interface. In addition, CLI’S only require a user to execute a few lines to perform a task. GUI’S use a mouse and keyboard to navigate and control and an operating or file system using a GUI is going to be much slower than that of a user working with command line. A computer that is only using the command line takes a lot less of the computer’s systems resources than a GUI. Although a GUI allows a user to create shortcuts, tasks or other similar actions, it doesn’t compare to what is available through a command line. Using a command line interface enables a user to script a sequence of commands to perform a task or execute a program.
Settings changeability aside, Mac is easier to use. First-time users have an easier time doing things on the Mac OS X than with Windows. At one point, the Mac's OS was so much easier to use than the PC's OS, there was no contest whatsoever. Today, however, Windows XP has greatly reduced the gap between the two systems.
In programming, computer engineers instruct computers how, to do their jobs or desired functions line by line. There are many forms of computer software engineers. There are computer applications software engineers who analyse user needs and designs and then build, maintain, or perfect specialized utility systems or applications already within the system. Computer applications engineers have a multitude of computer programming languages they have to use on a daily basis. Generally the favorite languages used are C, C++, and Java. The less popular languages that are used are Fortran and COBOL. Software engineers may also also develop packaged systems, systems software, or even create personalized applications. Computer systems software engineers are responsible for designing the maintenance and construction of a company's computer systems, while also planning the systems future growth. Computer systems software engineers analyse the needs of each specific department while working with a company and advise the company on which technical direction to follow. Computer systems software engineers often help set up the technical systems of the company within the departments. The computer systems software engineers will also sometimes set up the companies intranets systems. Specifically the ones that link the company's computer systems with the organization and make communications between departments run faster and smoother. Computer
User Interface in Video games holds more value than most could realize. When you play a video game, the user interface is usually the number one thing you spend time “interacting” with when you play the game. In order to even play it, you have to use the options in front of you the play. It usually comes in the form of a group of menus or a small display showing the buttons that you need to use, like shortcuts for your abilities. It can display information such as your health, or the resource you need to use the abilities you have, or even enemy health and position. It’s painfully clear that without any of the information that your user interface provides, that it would become increasingly difficult to make a decision, especially if the information displayed to you isn’t pertinent to you completing the game. But really, the more important question lies behind this thought. What makes good User Interface in Games?
- To increase customer base, Apple should make their GUI (of Mac OS) more user friendly. This is essential when a customer makes the transition from Windows OS to the Mac OS.
First reason for that is it allows us to add capabilities to physical system. And because of that we merge computing and communication with physical process and it brings us many benefits, like system will be more safe and efficient, the cost of construction and operation will be reduce and we can build a complex system that provide us a new capabilities. Other advantages are: we can get fast way to ensure safety in various real world processes, we can ensure efficiency, it will improve the quality of life for countless people, etc.
...for computer techs it would be hard for people to have a reliable computer. This is a growing career field. There are so many different jobs in this field.
A Terminal Operating System, or TOS, is a key part of the supply chain and primarily aims to control the movement and storage of various types of Cargo in and around a Container terminal or Port. The systems also allow the users to make better use of your assets, labor and equipment, plan your workload, and get up to the minute information which allows for more timely and cost-effective decision making.

Imagine asking your computer to do something in the same way you would ask a friend to do it. Without having to memorize special commands that only it could understand. For computer scientists this has been an ambitious goal; that can further simplify computers. Artificial Intelligence, a system that can mimic human intelligence by performing task that usually only a human can do, usually has to use a form of natural language processing. Natural language processing, a sub-field of computer science and artificial intelligence, concerns the successfully interaction between a computer and a human. Currently one of the best examples of A.I.(Artificial Intelligence) is IBM 's Watson. A machine that gained popularity after appearing on the show
Modern society heavily depends on the abilities of computers, Information Technology, and information processing. As such, since access to information 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 a human-computer interaction on a visual plane, and took computing to an entirely new level of experience. The first GUI started to emerge, as stated above, in the early 1980s, and within the last 3 decades have completely dominated the way in which human-computer communication occurs. Although some sources argue about it, it is acknowledged that the first company to use a proper graphical user interface was Apple. In 1984 they released the Macintosh computer, which used a graphical system to present information on the screen using boxes and taskbars, and utilized a revolutionary pointer device, now widely known as the mouse. Following this event, other companies started releasing their versions of GUI based operating systems, until in 1995 Microsoft presented Windows 95, which soon became a dominant power on the market, and along with its later installments, led Microsoft to be the IT giant of the 20th century. Since its appearance, the GUI have greatly influenced the IT-centered society, and the role computing and digital devices play in its growth.
Information Retrieval (IR) is to represent, retrieve from storage and organise the information. The information should be easily access. User will be more interested with easy access information. Information retrieval process is the skills of searching for documents, for information within documents and for metadata about documents, as well as that of searching relational databases and the World Wide Web. According to (Shing Ping Tucker, 2008), E-commerce is rapidly a growing segment in the internet.
Virtually all UNIX-based or UNIX-like systems require specific log on procedures. Depending upon an individuals access permissions, one is generally assigned an account or group with which to access terminals or workstations. User accounts, as these are typically described, can generally be assigned different access credentials depending on that individual's requirements. For the most part, user accounts have a limit to which a...
Computers are helpful because they offer a wide range of functions and services that are not available anywhere else. There are four main uses: word processing, internet/communications, digital video/audio composition, and desktop publishing. Although one can create a typed paper with a typewriter, the computer has more features
Operating systems work in two ways, by managing the hardware and software resources of the computer. Managing the hardware and software resources, is important because different programs and input methods go through the central processing unit (CPU) and both take up memory, storage and input/output bandwidth for their own purposes. Secondly, providing a consistent application interface, is critical if there is more than one of a specific type of computer using the same operating system, or if the computer’s hardware can be updated. A consistent application program interface (API) creates a way for a software developer to write an application on one computer and know that it will run on another of the same type, even if the memory and storage are different between computers.
Most video cards support the OpenGL and DirectX libraries. These libraries include commands for manipulating graphics that programmers can include in their code. Some of these commands may include moving or rotating an object, morphing polygons, or casting light and creating shadows. By using standard OpenGL or DirectX functions, it makes it easier for developers to create graphically-oriented programs. Of course, it also makes it necessary for the computer to include a supported video card in order for the program to
Input is really important for the computer. Through this device, users are allows to enter data or instructions into a computer. It changed something on the screen through the response. There are many kinds of input device for users to select depending on their application to get the result they want. There are many input technologies, for example, keyboard, pointing device, trackball, touch screen, touchpads and audio input. These devices can help users to connect with computer system directly.
