Computer Science Crash Course EP7

What is the main function of a CPU in a computer?

• To process instructions

• To manage network connections

• To store data permanently

• To display graphics

What makes a CPU programmable?

• Its ability to perform arithmetic operations

• Its ability to be controlled by software

• Its ability to connect to the internet

• Its ability to store data

What does the opcode in an instruction specify?

• The data to be processed

• The memory address to read from

• The operation to be performed

• The register to save the result

What is the result of executing an ADD instruction?

• Subtracting two numbers

• Adding two numbers

• Dividing two numbers

• Multiplying two numbers

What does a JUMP instruction do?

• It stops the program

• It subtracts two numbers

• It changes the order of instructions

• It adds two numbers

Why is a HALT instruction necessary?

• To jump to a new instruction

• To add two numbers

• To stop the CPU from processing

• To subtract two numbers

What is an infinite loop?

• A program that stops immediately

• A program that runs forever

• A program that does not use loops

• A program that runs a fixed number of times

What is the purpose of conditional jumps like JUMP_NEGATIVE?

• To jump based on a specific condition

• To subtract numbers conditionally

• To add numbers conditionally

• To continue executing the next instruction

What limitation does using 4 bits for memory addressing impose?

• It limits the memory addressable to 32 locations

• It limits the memory addressable to 16 locations

• It limits the CPU to 16 different instructions

• It limits the CPU to 32 different instructions

What was significant about the Intel 4004 processor?

• It was the first to support over 1000 instructions

• It was the first CPU put into a single chip

• It was the first to use variable length instructions

• It was the first to use a 64-bit architecture
