CCS 225 Midterm Part 1

Which of the following is the most basic type of computer architecture?

• Von Neumann architecture

• Harvard architecture

• RISC architecture

• CISC architecture

What is the difference between primary memory and secondary memory?

• Primary memory is faster and more expensive than secondary memory.

• Secondary memory is faster and more expensive than primary memory.

• Primary memory is volatile and secondary memory is non-volatile.

• Secondary memory is volatile and primary memory is non-volatile.

What is the difference between a register and a cache?

• Registers are faster and more expensive than caches.

• Caches are faster and more expensive than registers.

• Caches are smaller and store fewer data than registers.

• Caches are inside the CPU while registers are on the motherboard

What is the purpose of the central processing unit (CPU)?

• To store data

• To execute instructions

• To connect to I/O devices

• To control the flow of data and instructions

What is pipelining?

• A technique for executing multiple instructions simultaneously.

• A technique for storing data in memory more efficiently.

• A technique for reducing the power consumption of the CPU.

• A technique for improving the security of the computer.

What is the difference between a RISC architecture and a CISC architecture?

• CISC architectures have a larger instruction set and each instruction is more complex.

• RISC architectures have a smaller instruction set but each instruction is more complex.

• CISC architectures are typically faster and more power-efficient than RISC architectures.

• RISC architectures are typically faster but less power-efficient than CISC architectures.

What is multithreading?

• A technique for executing multiple instructions simultaneously on a single CPU core.

• A technique for executing multiple instructions simultaneously on multiple CPU cores

• A technique for improving the performance of memory-intensive applications.

• A technique for improving the performance of any computationally-intensive application.

Which of the following is NOT a part of the central processing unit (CPU)?

• Control unit

• Arithmetic logic unit (ALU)

• Memory

• Registers

What is cache memory?

• A small, fast memory that stores frequently accessed data

• A large, slow memory that stores all data and instructions

• A type of memory that is used to store the operating system

• A type of memory that is used to store graphics data

What is the difference between a 32-bit processor and a 64-bit processor?

• A 32-bit processor is faster than a 64-bit processor.

• A 32-bit processor can access 32 GB of memory, while a 64-bit processor can access 64 GB of memory.

• A 32-bit processor is more efficient than a 64-bit processor.

• A 32-bit processor can process 32 bits of data at a time, while a 64-bit processor can process 64 bits of data at a time.
