Answer is Wrong!
Answer is Right!
The correct answer is: D. All of the above.
A computer is an electronic device that can be programmed to carry out sequences of arithmetic or logical operations automatically. Modern computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks.
The basic components of a modern digital computer are:
- Input device: An input device is any peripheral that allows users to enter data into a computer. Common input devices include keyboards, mice, scanners, and digital cameras.
- Output device: An output device is any peripheral that allows users to view or receive data from a computer. Common output devices include monitors, printers, and speakers.
- Central processing unit (CPU): The CPU is the “brain” of the computer. It is responsible for carrying out the instructions of a program.
- Memory: Memory is used to store data and programs. There are two main types of memory: RAM (random access memory) and ROM (read-only memory). RAM is temporary memory that is erased when the computer is turned off. ROM is permanent memory that is not erased when the computer is turned off.
- Storage: Storage is used to store data and programs permanently. Common storage devices include hard drives, solid-state drives, and optical drives.
These components work together to allow computers to perform a wide range of tasks.
