  1. TECHNOLOGY GUIDE ONE Computer Hardware

  2. TECHNOLOGY GUIDE OUTLINE TG1.1 Introduction TG1.2 Strategic Hardware Issues TG1.3 Computer Hierarchy TG1.4 Input and Output Technologies TG1.5 The Central Processing Unit

  3. LEARNING OBJECTIVES • Identify the major hardware components of a computer system. • Discuss the strategic issues that link hardware design to business strategy. • Describe the hierarchy of computers according to power and their respective roles. • Differentiate the various types of input and output technologies and their uses.

  4. LEARNING OBJECTIVES (continued) • Describe the design and functioning of the central processing unit. • Discuss the relationships between microprocessor component designs and performance. • Describe the main types of primary and secondary storage.

  5. Hardware consists of: • Central processing unit (CPU) • Primary storage • Secondary storage • Input technologies • Output technologies • Communication technologies

  6. TG1.2 Strategic Hardware Issues • How do organizations keep up with the rapid price and performance advancements in hardware? • How often should an organization upgrade its computers and storage systems? • Will upgrades increase personal and organizational productivity? • How can organizations measure such increase? • How should organizations determine the need for new hardware infrastructures? • How do organizations manage employees who can “work from anywhere?”

  7. TG1.3 Computer Hierarchy • Supercomputers • Mainframe Computers • Midrange Computers • Microcomputers

  8. TG1.4 Input and Output Technologies Input technologies Human data-entry Source-data automation

  9. Various Human Input Devices • Trackball • Pointing Stick • Digital Pen • Web Camera • Wii • Bluetooth Laser Virtual Keyboard • The Maltron Keyboard

  10. Multimedia Technology • Multimedia technology • Merges capabilities

  11. TG1.5 The Central Processing Unit Central processing unit (CPU) Microprocessor • Control unit • Arithmetic-logic unit (ALU) • Registers

  12. Computer Memory Two basic categories of computer memory: • Primary Storage • Secondary Storage

  13. Memory Capacity • Bit • Byte

  14. Hierarchy of Memory Capacity • Kilobyte • Megabyte • Gigabyte • Terabyte • Petabyte • Exabyte • Zettabyte

  15. Main Types of Primary Storage • Registers • Random access memory (RAM) • Cache memory • Read-only memory (ROM)

  16. Secondary Storage Secondary Storage • Magnetic tape (sequential access) • Magnetic disks (direct access) • Optical storage devices • Flash Memory devices

  17. Optical Storage Devices Optical storage devices • Compact Disk, Read-Only Memory (CD-ROM) • Digital Video Disk (DVD)
