PROCESSORS

Question 1

Quad core processor

Answer 1

Four individual processing cores.

Independent execution of instructions.

Simultaneous task performance.

Improved performance and speed.

Used in high-performance computers.

Question 2

Single core processor

Answer 2

Single core on a chip

Running a single thread or single process at a time.

Performance cannot be improved further using methods like increasing clock speed, adding more transistors, enlarging CPU cache, or adding execution units.

Question 3

Dual core processor

Answer 3

• Two processors on a single chip.
• Each processor has its own cache and controller.
• Operates as efficiently as a single processor.
• Linked cores enable faster operations compared to a single-core CPU.

Question 4

Multi Core Processor

Answer 4

has multiple independent cores in one chip, each acting as a separate CPU.

Question 5

How a Multi-Core Processor Works:

Answer 5

• Multiple tasks, better performance
• OS/software task distribution
• Shared cache and memory bus
• Equal memory and I/O access
• Lower clock speeds, less heat and power

Question 6

Benefits of Multi-Core Processors:

Answer 6

• Executes multiple instructions at once.
• Better handling of multiple applications.
• Better performance-per-watt.
• Software optimization improves performance over time
