Software Software refers to the programs, which are required to operate the computer. The terms input and output say if data flow into or out of the computer. General Purpose Registers, Pointer Registers, Segment Registers, Index Registers, Flags Register and Instruction Pointer Register, depending upon their functions. Control Unit: This unit is also called programme controller and is the most complex unit. Application programs:Thy defined the way in which the system resources are used to solve the computing problems. As of 2007 , most motherboards use the standard form factor — even those found in and computers, which have not been built from commodity components. Hard disks, Compact Disks, Floppy disks are the examples of secondary storage devices.
Information stored on computer hardware is often called software. As the name implies, vector processors deal with multiple pieces of data in the context of one instruction. Its size is typically expressed in inches as a diagonal measurement from one corner of the screen to the opposite. It is a high-speed memory which holds only data from immediate processing and results of this processing. Switch is like a Hub but built in with advanced features. See Also: In short, an input unit performs the following functions. However, the basic organization remains the same for all computer systems.
A desktop computer consists of a computer case and a separate monitor, keyboard, and mouse. It comes in various shapes and sizes, but a typical tower model is between 15-25 inches high. It is the nerve centre because each unit of the computer works under the supervision of this unit. The processing devices perform the actual processing of the data. Additional peripherals such as and were provided as expansion cards.
Archived from on December 10, 2005. Ideally, a dual core processor would be nearly twice as powerful as a single core processor. Hardware and Software: The Physical Computer System, i. Archived from on September 23, 2015. Recent standard network cards built with Gigabit 1000Mbps connection speed. These cores can be thought of as different floors in a processing plant, with each floor handling a different task. In computer network technology, there are several types of networks that range from simple to complex level.
Array processors or have multiple processors that operate in parallel, with no unit considered central. Are physical components and thus, is hardware. It is a pathway for data flowing between components. Storage unit also consist of storage devices, which stores the data on permanent basis. This unit is responsible for all events inside the computer. Hence, before supplying the results to the outside world, it must be converted to human acceptable readable form.
This is the Level-2 Cache memory or secondary cache. A modern processor may contain billions of transistors. A computer system consists of both hardware and information stored on hardware. Power supply - Without a power supply none of the components needing power would work, which is basically all components. Once data is entered, they convert it into an internal form that can be processed by the central processing unit.
Larger systems are even faster. Data and instructions enter input units in forms that depend upon the particular device used. This transformation is accomplished by units that called input interfaces. They include the monitor and speakers. The tape is usually ½ in width and of varying length and is made of plastic material.
This chipset determines, to an extent, the features and capabilities of the motherboard. These early experimental designs later gave rise to the era of specialized like those made by and.

The arithmetic unit has the ability of performing all the ordinary operations of addition, subtraction, multiplication and division at a very high speed. Hard drive A hard drive is magnetic media that stores information permanently. Another additional advantage is that additional data can be inserted in this input unit which is not possible in punched paper tape or punched card after the tape or card has been punched.
