Basics of Computer :: 1 1 Basics of Computer 1.1 INTRODUCTION In this lesson we present an overview of the basic design of a computer system: how the different parts of a computer system are organized and various operations performed to perform a specific task. You would have observed that instructions have to be fed into the computer in a systematic order to perform a specific task. Computer components are divided into two major categories‚ namely‚ hardware and software. In this lesson we

Computer Mouse: Consumer Driven Innovation The computer mouse controls the pointer on a computer screen‚ allowing a user to navigate throughout programs‚ websites‚ etc. The mouse is moved around a surface by the user’s hand in order to translate that movement to the pointer on the computer screen. Computers were only invented shortly before the earliest mice were developed‚ and there were very few computers around. There was little demand for an invention like this‚ but before the mouse was invented

With increasing popularity of computer games‚ and multimedia home PC users often need an unexpensive computer system upgrade. By building a custom computer one is able to combine componenets‚ and operating system to provide maximal gaming performance. Computers are often called number manipulators‚ because of their ability to run millions of mathematical operations per second (White 43). Computers use binary system of numbers‚ which allows them to operate system of microscopic switches called transistors

Design concepts in architecture: the porosity paradigm Sotirios D. Kotsopoulos 129 Franklin Street‚ # 203‚ Cambridge‚ Massachusetts 02139‚ USA; e-mail: skots@alum.mit.edu Abstract: Presented is a paradigm of how a design concept can be converted into a system of production rules to generate designs. The rules are expressed by the means of shape grammar formalism. The paradigm demonstrates how porosity a concept transferred from biology‚ medicine and organic chemistry was implemented by architect
