Intro to Computer Architecture Flashcards
What is the Central Processing Unit (CPU).
The brain of the computer, it interprets and executes instructions from programs.
What does the Arithmetic Logic Unit do?
Performs arithmetic and logical operations
What does the Control unit (CU) do?
Directs the operation of the processor. Fetches, decodes then signals the ACl and Registers
What are Registers?
Small high speed storage locations located in the cpu.
The Program Counter does what?
Holds the address of the next instruction to be executed.
The Instruction Register does what?
Holds the current instruction being decoded or executed.
What does the Accumulator do?
Stores intermediate results of operations performed by the Arithmetic Logical Unit (ALU).
Memory Hierarchy
Prioritizes Speed, size, and, cost.
The fastest most expensive memory is used sparingly while Slower cheaper memory is used for bulk storage.
What type of memory is the fastest.
Cache Memory
True or False: Random Access Memory (RAM) is a non- volatile memory that permanently stores system info.
False - RAM is volatile. It temporarily holds data and instructions the CPU uses while programs are running.
What is Read-Only Memory (ROM)?
a non- volatile memory that permanently stores system info.
What does RAM stand for?
Random Access Memory
What does ROM stand for?
Read-Only Memory
What is Secondary Storage?
Non-volatile storage devices, like Hard Drives, Solid State Drives (SSD), and optical drives (DVDs) used for long-term storage.
