2. Explain the components of a CPU.
3. Explain the primary and the secondary memory.
.. Differintiate between RAM and ROM.
What are the four operations of a computer?
Answers
Answer:
1 The CPU is made up of three main components, the control unit , the immediate access store and the arithmetic and logic unit
2 KEY DIFFERENCE
Primary memory is also called internal memory whereas Secondary memory is also known as a Backup memory or Auxiliary memory. ... Primary memory data is directly accessed by the processing unit whereas Secondary memory data cannot be accessed directly by the processor
3 RAM data is volatile and is erased once computer is switched off. ... ROM have prerecorded data and it is used to boot computer. RAM data is static and remains in the computer even if computer is switched off.
Answer:
2.The two typical components of a CPU include the following: The arithmetic logic unit (ALU), which performs arithmetic and logical operations. The control unit (CU), which extracts instructions from memory and decodes and executes them, calling on the ALU when necessary.
3.The memory of a computer is classified in the two categories primary and secondary memory. Primary memory is the main memory of the computer where the currently processing data resides. The secondary memory of the computer is auxiliary memory where the data that has to be stored for a long time or permanently, is kept.
4.RAM, which stands for random access memory, and ROM, which stands for read-only memory, are both present in your computer. RAM is volatile memory that temporarily stores the files you are working on. ROM is non-volatile memory that permanently stores instructions for your computer.
5.A computer is a machine that, under a program's direction, performs four basic operations: input, processing, output, and storage. A program is a list of instructions that tells a computer how perform the four operations
