Module 4: CPU BASICS AND ORGANIZATIONS
LEARNING ACTIVITY
IDENTIFICATION: Answer the following statements. Write your answers on the blank space
provided before each number.
Central Processing Unit 1. It is originated way back in the mists of computer time when a single
massive cabinet contained the circuitry required to understand machine level program instructions
and execute operations on the data supplied.
Processor Register 2. A fast accessible location available to a digital processor's central
processing unit (CPU) and usually contain of a small amount of fast storage, although some
registers have specific hardware functions, and may be read-only or write-only.
Arithmetic Logic Unit (ALU) 3. It is the basic building block of the CPU.
Decode 4. One of the functions of CPU wherein all programs to be performed are translated into
Assembly instructions. Assembly code must be decoded into binary instructions, which are
understandable to your CPU.
Quad-Core CPU 5. A refined model of multiple core CPU features and design with four cores on
a single CPU.
Control Unit 6. This unit controls the operations of all parts of the computer but does not carry
out any actual data processing operations.
Logic Section 7. It is to perform operations such as comparing, selecting, matching, and merging
of data.
Hardwired Control Unit 8. The control signals that are important for instruction execution
control are generated by specially designed hardware logical circuits, in which we can not
modify the signal generation method without physical change of the circuit structure.
Memory or Storage Unit 9. This unit can store instructions, data, and intermediate results.
Cache Memory 10. A kind of memory which is placed in the processor’s chip or may be placed
separately linked by a bus.
Single-Core CPU 11. It is the oldest type of CPU which is available and employed in most of the
personal and official computers.
Arithmetic Section 12. It is to perform operations like addition, subtraction, multiplication, and
division. All complex operations are done by making repetitive use of the above operations.
Random Access Memory (RAM) 13. It is the main memory of the computer.
Register 14. It is used to store data such as instruction, storage address and any kind of data like
bit sequence or any characters etc.
Data Bus 15. It carries data between processor and the memory.
Hexa-Core Processors 16. It is another multiple core processor which is available with six cores
and can execute the task which works rapidly than the quad-core and dual-core processors.
Memory Address Register (MAR) 17. It stores the address of the current instruction being
executed.
Bus 18. A communication system that is used to transfer the data among all the components of
the computer.
Memory 19. It holds both data and instructions.
Multi-Core CPU 20. It means that more than one processor is embedded in the CPU Chip that
work simultaneously and the benefit is that it rapidly achieved the high performance, consuming
less energy power and the multi-tasking or parallel processing is really efficient.
