Perform calculations on input data. Output the result. A computer is a machine that performs calculations. Most tasks that a computer performs follow these steps: Accept input data. Perform calculations on input data. Output the result. Computer's Hardware

Central Processing Unit (CPU) Arithmetic And Logic Unit (ALU) Hardware of a computer can be subdivided into the following components. Input Unit Output Unit Memory Unit Central Processing Unit (CPU) Arithmetic And Logic Unit (ALU) Secondary Storage Unit Computer's Hardware

Central Processing unit (CPU) The Central Processing unit (CPU) 中央處理機 is a microprocessor chip that is central to the entire computer. Computer's Hardware

Central Processing Unit (CPU) Every CPU runs at a certain clock speed. 1 Hz = one elementary operation per second. Recent CPU's have clock speeds as high as 3 GHz (= 3*109 Hz); such CPU's can perform as many as three billion operations in a single second! Computer's Hardware

Random Access Memory, (RAM) short-term memory A typical computer will have at least 512 MB of RAM storage = 512*106*8 bits. Computer's Hardware

Memory ROM = read-only memory. A ROM chip Computer's Hardware

Secondary Storage Two types of secondary storage are popular: hard disks and CD-ROMs. Computer's Hardware

A CD-ROM is a plastic disc with microscopic pits pressed into it. Cross section of a CD disc Computer's Hardware

Inside a CD Player Computer's Hardware

A standard CD-ROM has a capacity of 650 MB, or 650 * 106 * 8 bits A DVD-ROM, that works like a CD but can have denser pits, has a capacity of 4.5 GB, or 4.5*1099*8 bits. Computer's Hardware

Hard Disk Basics Hard disks have a hard platter to hold the magnetic mediums. Use magnetic recording techniques. Computer's Hardware

Inside a Hard Disk Computer's Hardware

Storing the Data Data is stored on the surface of a platter in sectors and tracks. Tracks are concentric circles, and sectors are pie-shaped wedges on a track, like this: A typical track is shown in yellow; a typical sector is shown in blue. A sector contains a fixed number of bytes -- for example, 256 or 512. Either at the drive or the operating system level, sectors are often grouped together into clusters. Computer's Hardware

Graphics Card Basics The CPU, with software applications, sends information about the image to the graphics card. Computer's Hardware

3. It then sends that information to the monitor through a cable. Graphics Card Basics The graphics card decides how to use the pixels on the screen to create the image. 3. It then sends that information to the monitor through a cable. Computer's Hardware

Graphics Card Basics Computer's Hardware

Sound Card Before the invention of the sound card, a PC could make one sound - a beep. It could change the beep's frequency and duration, but it couldn't change the volume or create other sounds. Developers created music for the earliest PC games using beeps of different pitches and lengths. This music was not particularly realistic Computer's Hardware

Sound Card PC sound card Computer's Hardware

Sound Card Game designers use 3-D sound to provide fast-paced, dynamic sound that changes based on a player's position in the game. Surround sound also uses sound from several directions, but the sound does not change based on the listener's actions. Surround sound is common in home theater systems. Computer's Hardware

BIOS On virtually every computer available, the BIOS makes sure all the other chips, hard drives, ports and CPU function together. What BIOS Does Its most important role is to load the operating system. Computer's Hardware

Ports Port : connect any peripheral device to a computer. Most computers are equipped with at least the traditional serial and parallel ports. Another port that is becoming increasingly standard is the USB (for "Universal Serial Bus") port. This type of port can be used to connect any of a wide range of devices. Many devices nowadays feature a USB connection. Computer's Hardware

USB Connect toward the computer. Connect to individual devices. Computer's Hardware

Mouse In connection with a monitor, a mouse allows the user to graphically interact with the computer. Inside a mouse Computer's Hardware

allows the user to input data into the computer. keyboard allows the user to input data into the computer. Computer's Hardware

Monitor Enables the computer to provide information to the user by displaying it on the screen. Computer's Hardware

Speakers/headphones Enables the user to listen to the sounds produced by the computer. Computer's Hardware

Microphone allows the user to record external sound into the computer; also for use in speech recognition. Computer's Hardware

nowadays mainly for use in computer games. Joystick nowadays mainly for use in computer games. Computer's Hardware

Inkjet Printer Laser Printer Printer allows the user to print documents. Inkjet Printer Laser Printer Computer's Hardware

Webcam A simple Webcam consists of a digital camera attached to your computer. Computer's Hardware
