Study Notes
Computer Peripheral Devices
- The CPU is not a peripheral device. Peripheral devices are input/output devices.
System Unit Ports
- A port is a place in a system unit that allows data transfer between devices and the computer.
Read-Only Memory (ROM)
- ROM is computer memory where users cannot write new information or instructions.
Groups of Bits
- A group of 8 bits is called a byte.
Megabyte Conversion
- A megabyte (MB) is equivalent to 1024 kilobytes (KB).
- A megabyte (MB) is equivalent to 1024 * 1024 bytes.
Device Drivers
- Device drivers allow input/output devices to communicate with the rest of the computer system.
Memory Types
- The two basic types of computer memory are primary and secondary.
Optical Disk
- A CD is a non-erasable disk that stores digitized audio information.
Outputting Data
- Outputting data is the process of producing useful information for the user.
Output Unit's Function
- The output unit's function is to convert data entered by the user into a computer-understandable form.
- It converts data received from the computer into a format that the user can understand.
Smallest Unit of Data
- The smallest unit of data in a computer is a bit.
Input Unit Functions
- The input unit reads instructions and data from the outside world.
Data and Program
- Input is the raw material of a computer system.
- Processed data from a computer is the output.
Computer Characteristics
- Computers are characterized by speed, accuracy, and capacity.
