Setting Peripherals

Computer peripherals are additional computer equipment needed for the purpose - other purposes. For example, network connections, printing, or take pictures. Peripheral include Printer, Scanner, Modem, Network Card, and others. Installation includes the installation of physical peripherals and software installation. Physical installation includes installation of peripherals with the good and true, and peripherals installation software includes the introduction of the operating system is to install the drivers needed. 1) PrinterThe printer is an output component that is classified as Hard Copy Device. That is a tool used to print the output of the process performed by the computer either text or graphics directly using paper or other media.There are three types of printers on the market.Dot...

Local Area Network (LAN)

A local area network (LAN) is a computer network that connects computers and devices in a limited geographical area such as home, school, computer laboratory or office building. The defining characteristics of LANs, in contrast to wide area networks (WANs), include their usually higher data-transfer rates, smaller geographic area, and lack of a need for leased telecommunication lines. ARCNET, Token Ring and other technology standards have been used in the past, but Ethernet over twisted pair cabling, and Wi-Fi are the two most common technologies currently in use. As larger universities and research labs obtained more computers during the late 1960s, there was an increasing pressure to provide high-speed interconnections. A report in 1970...

History of Microsoft Windows

Microsoft has taken two parallel routes in its operating systems. One route has been for the home user and the other has been for the professional IT user. The dual routes have generally led to home versions having greater multimedia support and less functionality in networking and security, and professional versions having inferior multimedia support and better networking and security. The first version of Microsoft Windows, version 1.0, released in November 1985, lacked a degree of functionality and achieved little popularity, and was to compete with Apple’s own operating system. Windows 1.0 is not a complete operating system; rather, it extends MS-DOS. Microsoft Windows version 2.0 was released in November 1987 and was slightly more popular...

Microsoft Windows

Microsoft Windows is a series of software operating systems and graphical user interfaces produced by Microsoft. Microsoft first introduced an operating environment named Windows on November 20, 1985 as an add-on to MS-DOS in response to the growing interest in graphical user interfaces (GUIs). Microsoft Windows came to dominate the world's personal computer market, overtaking Mac OS, which had been introduced in 1984. As of October 2009, Windows had approximately 91% of the market share of the client operating systems for usage on the Internet. The most recent client version of Windows is Windows 7; the most recent server version is Windows Server 2008 R2; the most recent mobile OS version is Windows Phone...

Windows Registry

The Windows Registry is a hierarchical database that stores configuration settings and options on Microsoft Windows operating systems. It contains settings for low-level operating system components as well as the applications running on the platform: the kernel, device drivers, services, SAM, user interface and third party applications all make use of the Registry. The registry also provides a means to access counters for profiling system performance. When first introduced with Windows 3.1, the Windows registry's primary purpose was to store configuration information for COM-based components. With the introduction of Windows 95 and Windows NT, its use was extended to tidy up the profusion of per-program INI files that had previously been used to store configuration settings for Windows programs. .INI...

Types of Operating Systems

Types of Operating Systems : Real-time Operating System: It is a multitasking operating system that aims at executing real-time applications. Real-time operating systems often use specialized scheduling algorithms so that they can achieve a deterministic nature of behavior. The main object of real-time operating systems is their quick and predictable response to events. They either have an event-driven or a time-sharing design. An event-driven system switches between tasks based on their priorities while time-sharing operating systems switch tasks based on clock interrupts. Multi-user and Single-user Operating Systems: The operating systems of this type allow a multiple users to access a computer system concurrently. Time-sharing system can be classified as multi-user systems as they enable...

Operating System

An operating system (OS) is software, consisting of programs and data, that runs on computers and manages computer hardware resources and provides common services for efficient execution of various application software. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between application programs and the computer hardware, although the application code is usually executed directly by the hardware and will frequently call the OS or be interrupted by it. Operating systems are found on almost any device that contains a computer—from cellular phones and video game consoles to supercomputers and web servers. Examples of popular modern operating systems for personal computers are (in alphabetical order): GNU/Linux, Mac OS X, Microsoft...

Using Computer Correctly

As stated before, componen of computer include hardware, software, and brain ware. The kind of computer we often use is PC (personal computer). Usualy, a PC consists of hardware including one unit of CPU, input devises  in form of mouse and keyboard, and output device like monitor. Those are minimum harrdware that computer can be operated. Sometimes, additional devices like printer for printing data on copy like paper, stabilizer fir stabilizing voltage and speaker for output device producing sound may be required. To be operable, a computer must be completed with software including operating system and application programs. Other significant component other than hardware and software is brain ware. A computer will provide with optimal...

History of Computer

The history of computer started in 1940, namely by invention of first electronic computer on the wordl know as ABC (Atanasoff and Berry Computer) taken from names of its invertor. In the same decade, Dr. John W M. Maunchly with J. Presper Eckert, Jr., invented a kind of computer knows as ENIAC (Electronic Numerical Integrator Anda Computer) It is made for calculating tables of bullet trajectories for US army. ENIAC was thousands faster than provious electromechanical computer, indicating a heap in computer technology. Weight of ENIAC reached 30 tons and required a room in size of 1,800 squarefeet (167m2). By total 18,000 vacuum tubes, ENIAC required great amount of electric power, reaching 174 kilowatts that there was a joke at that time "If...

Defenition of Computer

Literally, the term "computer" is derived from "compute" meaning calculate. Perhaps, in follows initial objective of creating computer, namely hoe create an adding a=machine capable to do many calculations accurately. However, during its development, this machine changes to be multipurpose machine, not only for calculating only. Computer has developed to be versatile machine that may change functions based on necessities. Sometimes, it is used as typewriter, calculator, drawing creator, song and film player, etc. Computer means a series a group electronic machines consiting of thousands even millions of components able to cooperate and to form an order and thorough work system. This system can then be used to carry out a series of tasks automatically...
