Chapter 1. Introduction to Computer Organization and Computer Evolution I. Computer Organization and Computer Architecture In describing computers‚ a distinction is often made between computer architecture and computer organization. Although it is difficult to give precise definitions for these terms‚ a consensus exists about the general areas covered by each. Computer Architecture refers to those attributes of a system visible to a programmer or‚ put another way‚ those attributes that have a

to perform operations on data.[1] Quantum computers are different from digital computers based on transistors. Whereas digital computers require data to be encoded into binary digits (bits)‚ each of which is always in one of two definite states (0 or 1)‚ quantum computation uses qubits (quantum bits)‚ which can be in superpositionsof states. A theoretical model is the quantum Turing machine‚ also known as the universal quantum computer. Quantum computers share theoretical similarities with non-deterministic

Grace Loraine M. Borres BSCOE II-3 Assignment No. 1 An internal bus serves as the communication highway of the motherboard. It links the different parts of the computer to the CPU and the main memory. Its primary task is to send data and instructions to the different parts within the motherboard‚ including the external bus. The external type of motherboard bus‚ which is also known as the expansion bus‚ serves as the interface for peripheral devices like hard disks‚ CD-ROM drives‚ and flash

INTRODUCTION Computer is defined as a combination of electro-mechanical devices (Hardware) capable of accepting data or information‚ processing‚ storing‚ and providing output under the control of some instructions and commands called programs (Software). Computers are machines that perform tasks or calculation according to a set of instruction or programs. Introduce in 1940s the first fully electronic computers were huge machines that required teams of people to operate. Compared to those early

These individuals are typically completely comfortable with the computer technology that surrounds them in their daily lives. One of the most ancient forms of communication known as hand writing is being replaced by typing. Even with the invention of the typewriter‚ it was still not uncommon to handwrite memos‚ letters

Supercomputer Supercomputer is a broad term for one of the fastest computers currently available. Supercomputers are very expensive and are employed for specialized applications that require immense amounts of mathematical calculations (number crunching). For example‚ weather forecasting requires a supercomputer. Other uses of supercomputers scientific simulations‚ (animated) graphics‚ fluid dynamic calculations‚ nuclear energy research‚ electronic design‚ and analysis of geological data (e.g.
