Answers
Explanation:
1. Computer memory is of two basic type – Primary memory(RAM and ROM) and Secondary memory(hard drive,CD,etc.). Random Access Memory (RAM) is primary-volatile memory and Read Only Memory (ROM) is primary-non-volatile memory. It is also called as read write memory or the main memory or the primary memory.
2.Principal components of a CPU include the arithmetic logic unit (ALU) that performs arithmetic and logic operations, processor registers that supply operands to the ALU and store the results of ALU operations, and a control unit that orchestrates the fetching (from memory) and execution of instructions by directing the ...
1. computer has two main memories : primary and secondary memory
2. the CPU is mainly used for :
(1) the arithematic unit and logic unit
(2) memory or storage unit
3. RAM is the non-volatile memory..
4. computer hardware includes the physical parts of a computer such as monitor, keyboard, mouse, CPU and many more.
software is the set of instructions that can be stored and run by hardware.
5. a program is executable software that runs on a computer. it is similar to a script but is often much larger in size.
6. GIGO (garbage in garbage out) is the concept that flawed or nonsense input data.
