In these lectures, we begin our three-lecture exploration of Computer Hardware. We start by looking at the different types of computer components and how they interact during basic computer operations. Next, we focus specifically on the CPU (Central Processing Unit).
RESTRICTED INTRODUCTION TO COMPUTER HARDWARE CHAPTER ONE INTRODUCTION DEFINITION OF COMPUTER. What Is a Computer? A Computer is an electronic device, operating under the control of instructions stored in its own memory, that can accept data, process the data according to specified rules, produce results, and stores the results for future use.
Computer hardware is divided into two main categories: the system unit and peripherals. The system unit contains the electronic components used to process and temporarily store data and instructions (Figure 3.2).
A basic introduction into computer hardware and a practical guide to using computers. Section I. INTRODUCTION TO COMPUTER HARDWARE. Technical Specifications. Hardware: the physical ‘touchable/hard’ components of a computer. Software (many are often referred to as “Apps”) : the programs that control or run the hardware.
Chapter Overview. Th is chapter introduces you to the computer, inside and out. You’ll learn about the types of computers that are in use today, and you’ll get an overview of dif erent ways that computers are used in our society.
The term hardware refers to all of the physical devices, or components, that a computer is made of. A computer is not one single device, but a system of devices that all work together.
A computer system consists of both hardware and information stored on hardware. Information stored on computer hardware is often called software. The hardware components of a computer system are the electronic and mechanical parts. The software components of a computer system are the data and the computer programs.
