WHAT IS COMPUTER? The word “Computer” is derived from the word “compute” which means to calculate. In the past‚ the computer was normally considered to be a calculating device which used to calculate arithmetic operations. But today‚ computer is used in every field of daily life to solve problems of different kinds. Therefore‚ a computer can be defined as: Definition: Computer is an electronic device that is used to solve different kinds of problems depending on a set of instructions given

ABSTRACT By doing this lab tasks‚ we had learned about how to use the MSDOS editor and the MDA-8086 Experiment Board. The MSDOS editor was important in this task where we need to view‚ create‚ or modify of these files which are MATRIX.ASM‚ MATRIX_1.ASM‚ MATRIX_2.ASM‚ MATRIX_3.ASM and MATRIX_4.ASM for error. This editor makes those programs easy on being assemble for any error following the instructions given. A dot matrix is a 2-dimensional patterned array‚ used to represent characters‚ symbols

The Basic Computer Hardware Central Processing Unit: The central unit is the basic part of the computer and includes all the main computer parts. It is the heart of the computer system. It is responsible for executing‚ or running the software. The software programs are translated into a series of codes made up of 1s to 0s that the CPU can understand. Every code means a certain operation should take place. A CPU has various discrete units to help it in these tasks for example there is an arithmetic

integerated circuits. Very Large Scale(VLSI) and Ultra Large scale(ULSI) ensured that millions of components could be fit into a small chip. It reduced the size and price of the computers at the same time increasing power‚ efficiency and reliability. "The Intel 4004 chip‚ developed in 1971‚ took the integrated circuit one step further by locating all the components of a computer (central processing unit‚ memory‚ and input and output controls) on a minuscule chip." Due to the reduction of cost and the availability

James University of Phoenix POS/335 Monday April 9‚ 2012 Terance Carlson This paper will discuss three main operating systems‚ Windows‚ Linux‚ and OS X. All three of these operating systems have features which are unique unto themselves. Although there may be arguments as to which one of these three operating systems is better it really all comes down to what features are needed for each user. This paper will describe the features that each of these operating systems has to offer
