It can refer to all computer instructions in general or to any specific set of computer instructions. It is inclusive of both machine instructions and source code (more human-understandable instructions that must be rendered into machine code by compilers or interpreters before being executed). On most computer platforms‚ software can be grouped into a few broad categories: software is the basic software needed for a computer to operate. software refers to one or more computer programs and data

about to touch every aspect of our lives. Such a device that changes the way we work‚ live‚ and play is a special one‚ indeed. The Microprocessor has been around since 1971 years‚ but in the last few years it has changed the American calculators to video games and computers (Givone 1). Many microprocessors have been manufactured for all sorts of products; some have succeeded and some have not. This paper will discuss the evolution and history of the most prominent 16 and 32 bit microprocessors

Computer was invented by Charles Babbage in 1822. The computer is the most wonderful gift of science to the modern man. The computer can do all the works of man. Thus‚ after the invention of computer‚ the gap between man and machine has been bridged up.The dictionary meaning of the word "Computer" is an electronic calculating machine. Though a machine‚ it contains and provides innumerable informations. It may seem strange‚ but it is true that the memory and intelligence of a computer can be greater

Evolution of Microprocessor It is interesting to note that the microprocessor had existed for only 10 years prior to the creation of the PC! Intel invented the microprocessor in 1971; the PC was created by IBM in 1981. Now more than 20 years later‚ we are still using systems based more or less on the design of that first PC. The processors powering our PCs today are still backward compatible in many ways with the 8088 that IBM selected for the first PC in 1981. November 15‚ 2001 marked the 30th anniversary

Types of Storage Devices Physical components or materials on which data is stored are called storage media. Hardware components that read/write to storage media are called storage devices. Two main categories of storage technology used today are magnetic storage and optical storage. Primary magnetic storage o Diskettes o Hard disks (both fixed and removable) o High capacity floppy disks o Disk cartridges o Magnetic tape Primary optical storage o Compact Disk Read Only Memory (CD ROM)
