Topic 15: Basic Computer Architecture Flashcards
The processor is the part of the computer responsible for
processing data and instructions
ALU is part of the Core Processing Unit (CPU) and is responsible for
calculations and logic operations
The control unit sends out control signals which allow the processor to
read data from memory, write data to memory
Registers are the
temporary storage locations within the processor which hold data being transferred to/from memory
A typical computer structure consists of
input devices, Backing storage, main memory and out put devices feeding into the processor
The main memory is used to store
data and instruction currently in use and is divided into RAM and ROM
Buses are
connections which allow data to be transferred between the processor and Main Memory.
The 2 main buses are
Data bus and address bus
The data bus is either a
32 bit or 64 bit connection.
The data bus sends
instructions and data from memory to the processor and vice versa
The address bus is either a
32 bit or 64 bit connection
The address bus pinpoints
location in main memory to be written to/read from.
