What are the four basic functions that a computer can perform?

• Data manipulation, Data backup, Data transfer, Control

• Data processing, Data storage, Data movement, Control

• Data analysis, Data retrieval, Data transmission, Control

• Data computation, Data retention, Data communication, Control

What is the function of the Control Unit in a computer?

• Manages the computer's resources and orchestrates the performance of its functional parts in response to instructions

• Performs the computer's data processing function

• Moves data between the computer and its external environment

• Provides storage internal to the CPU

What is the purpose of the Address Bus in a computer system?

• To designate the source or destination of the data on the data bus

• To transmit command and timing information among system modules

• To control the access and use of the data and address lines

• To provide a path for moving data among system modules

What is the main function of the I/O module in a computer system?

• Exchange data directly with the processor

• Read data from or write data to an I/O module

• Issue read or write commands to memory relieving the processor of responsibility for the exchange

• Identify a specific device controlled by a particular I/O module

What are the three key concepts of the von Neumann architecture?

• Data and instructions stored in a single read-only memory, Execution occurs in a parallel fashion, Data and address lines are shared by all components

• Data and instructions stored in a single read-write memory, The contents of this memory are addressable by location, Execution occurs in a parallel fashion

• Data and instructions stored in a single read-write memory, The contents of this memory are addressable by location, Execution occurs in a sequential fashion

• Data and instructions stored in a single read-write memory, Execution occurs in a sequential fashion, Data and address lines are shared by all components

What is the purpose of the Data Bus in a computer system?

• To designate the source or destination of the data on the data bus

• To transmit command and timing information among system modules

• To control the access and use of the data and address lines

• To provide a path for moving data among system modules

What is the function of the Memory Management Unit (MMU) in a computer system?

• To manage the computer's resources and orchestrate the performance of its functional parts in response to instructions

• To perform arithmetic and logical operations on the data

• To move data between the computer and its external environment

• To provide storage internal to the CPU

What is the purpose of the Instruction Register in a computer system?

• To control the access and use of the data and address lines

• To transmit command and timing information among system modules

• To store the current instruction being executed by the CPU

• To provide a path for moving data among system modules

What is the main function of the Input/Output Controller in a computer system?

• To exchange data directly with the processor

• To read data from or write data to an I/O module

• To issue read or write commands to memory relieving the processor of responsibility for the exchange

• To identify a specific device controlled by a particular I/O module

What is the purpose of the Memory Buffer Register (MBR) in a computer system?

• To store the address of the next instruction to be executed

• To manage the computer's resources and orchestrate the performance of its functional parts in response to instructions

• To temporarily store data while it is being transferred between two locations

• To provide storage internal to the CPU
