Computer Specifications Updated

Computer specifications are a set of requirements that determine the hardware and software layout of a computer system in order for it to work at optimum level. When buying a computer there are certain specifications that one should look for. These include:
Processor: an electronic circuit that responds to and processes the numeric basic and instructions that execute computer programs and cause the computer to work. In other words, it is the brain of the computer. It is an electronic circuit that operates at the speed of an internal clock thanks to a quartz crystal that, when subjected to an electrical current, send pulses, called peaks. The clock speed also called cycle, corresponds to the number of pulses per second, written in Hertz (Hz). Thus, a 200 MHz computer has a clock that sends 200,000,000 pulses per second. Clock frequency is generally a multiple of the system frequency, meaning a multiple of the motherboard frequency.
Operating System: an interface between hardware and user which is responsible for the management and coordination of activities and the sharing of the resources of a computer, that acts as a host for computing applications run on the machine. As a host, one of the purposes of an operating system is to handle the resource allocation and access protection of the hardware. This relieves the application programmers from having to manage these details. The operating system most recommended is Windows Vista Home.
Memory: Computer memory refers to devices that are used to store data or programs on a temporary or permanent basis for use in an electronic digital computer. Each binary digit is called a bit and may be stored by any physical system that can be in either of two stable states, to represent 0 and 1. Such a system is called bistable. This could be an on-off switch, an electrical capacitor that can store or lose a charge, a magnet with its polarity up or down, or a surface that can have a pit or not. Today, capacitors and transistors, functioning as tiny electrical switches, are used for temporary storage and either disks or tape with a magnetic coating, or plastic discs with patterns of pits are used for long-term storage. Computer memory is usually meant to refer to the semiconductor technology that is used to store information in electronic devices. Current primary computer memory makes use of integrated circuits consisting of silicon-based transistors. There are two main types of memory: volatile and non-volatile. Thus a 1GB SDRAM means that you can store up to 1 billion bytes worth of information in your RAM. As it relates to your hard drive, a 80GB Hard Drive can hold up to 80 billion bytes of information on this secondary storage device.

Graphics: Graphics are visual presentations on the computer screen to brand, inform, illustrate, or entertain. These are may be photographs, drawings, graphs, or diagrams, or other images. Graphics often combine text, illustration, and color. Clarity or effective communication may be the objective, association with other cultural elements may be sought, or merely, the creation of a distinctive style.
Boot Hard Drive: a disk that a computer can start up or "boot" from. The most common type of boot disk is an internal hard drive, which most computers use to start up from. The operating system installed on the hard drive is loaded during the boot process. The hard drive is a central storage area for the programs being run and the documents or assets created. The boot hard drive should be 160GB, and 8MB DataBurst Cache. This means that the boot hard drive has the capacity to hold 160 billion bytes of information and the CACHE has the capability to hold 8 million bytes of information.
Video Card: also called video adapter, graphics-accelerator card, display adapter or graphics card is an expansion card whose function is to generate and output images to a display. Many video cards offer added functions, such as accelerated rendering of 3-dimensional scenes and 2-dimensional graphics, video capture. Video hardware can be integrated on the motherboard, as it often happened with early computers; in this configuration it was sometimes referred to as a video controller or graphics controller. A 256MB video card has the capability to hold 256 million bytes worth of information.
Hardware Support Services: the aspect that deals with the services that will be needed to maintain the computer. They offer preventative, diagnostic, repair and remedial services. It helps you to improve the management of your system and improve the effectiveness as a result.
Other information includes information about the sound capability of the computer, as well as details of the monitor that come with the system, such as its type and speed.
