3. 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.

4. 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)

5. 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

6. 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!

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

9. Secondary Storage Two types of secondary storage are popular:
hard disks
and CD-ROMs.

12. 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.

15. 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.

19. 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

21. 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.

22. 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.

23. 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.
