- 1What does CPU stand for?Central processing unit
- 2What is the CPU?The CPU (Central Processing Unit) is the part of a computer system that is commonly referred to as the "brains" of a computer. The CPU is also known as the processor or microprocessor. The CPU is responsible for executing a sequence of stored instructions called a program.
- 3What is virtual memory?Memory that appears to exist as main storage although most of it is supported by data held in secondary storage, transfer between the two being made automatically as required.
- 4what is cache memory?Cache memory, also called CPU memory, is random access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM. This memory is typically integrated directly with the CPU chip or placed on a separate chip that has a separate bus interconnect with the CPU.
- 5What does ROM stand for?Read-only memory.
- 6What is ROM?Read-only memory (ROM) is a class of storage medium used in computers and other electronic devices.
- 7What does RAM stand for?Random Access Memory
- 8What is RAM?Alternatively referred to as main memory, primary memory, or system memory, Random Access Memory is a hardware device that allows information to be stored and retrieved on a computer. RAM is usually associated with DRAM, which is a type of memory module. Because information is accessed randomly instead of sequentially like it is on a CD or hard drive, the computer can access the data much faster.
- 9What is a processor?A processor is the logic circuitry that responds to and processes the basic instructions that drive a computer. The term processor has generally replaced the term central processing unit (CPU). The processor in a personal computer or embedded in small devices is often called a microprocessor.
