What key components make up the general structure of the IAS computer?

• CPU, RAM, and hard drive

• Main memory, ALU, control unit, and I/O equipment

• Processor, cache, and bus

• Input devices, output devices, and storage

How are both data and instructions stored in the IAS computer's memory?

• As separate entities in different memory locations

• As binary codes within the same memory locations

• As ASCII characters

• As analog signals

What is the purpose of an opcode within an instruction?

• To specify the memory address of the data

• To indicate the operation to be performed

• To control the flow of data between registers

• To store the result of the calculation

How does the control unit of the IAS computer execute instructions?

• By executing all instructions simultaneously

• By fetching and executing instructions sequentially from memory

• By randomly selecting and executing instructions

• By waiting for external signals to trigger instruction execution

What is the purpose of a branch instruction?

• To transfer data between memory and registers

• To perform arithmetic operations

• To alter the sequence of instruction execution

• To modify the contents of memory locations

What is the significance of the address modify instruction?

• It allows for more efficient data storage.

• It enables the computer to perform complex mathematical calculations.

• It provides greater flexibility in addressing memory locations.

• It improves the speed of input/output operations.

What is the primary function of the ALU (Arithmetic and Logic Unit) in the IAS computer?

• To control the flow of data within the computer.

• To store and retrieve data from memory.

• To perform arithmetic and logical operations on data.

• To decode and execute instructions.
