ITEC 2360 Exam 1 Quiz

1. The chip that synchronizes or controls the timing of all computer operations is called_______________.

ALU

System Clock

RAM

ROM

The system clock is responsible for synchronizing and controlling the timing of all computer operations. It ensures that all components of the computer are working together at the correct speed and in a coordinated manner. The system clock generates regular electronic pulses that regulate the timing of various processes, such as fetching and executing instructions, accessing memory, and transferring data. Without the system clock, the computer would not be able to function properly and execute tasks in a synchronized and orderly manner.

2. Many of the electronic components in the system unit reside on a circuit board called the ___________________.

The motherboard is a circuit board that houses many electronic components in the system unit. It is responsible for connecting and providing power to these components, allowing them to communicate and work together. Without a motherboard, the system unit would not be able to function properly as it acts as the central hub for all the other components. Therefore, the motherboard is the correct answer to this question.

3. Three output devices would be ________________________.

Printer, LCD Monitor, CD Rom Drive

Printer, Keyboard, Mouse

Keyboard, Mouse, Scanner

LCD Monitor, Touch Screen, Microphone

The correct answer is Printer, LCD Monitor, CD Rom Drive. These devices are all examples of output devices. A printer is used to produce a hard copy of documents or images. An LCD monitor displays visual output from a computer or other electronic device. A CD Rom Drive is used to read data from a CD.

4. What are the 4 basic operations of the machine cycle?

Fetch, debone, clock speed, gigahertz

RAm, decode, arithmetic operations, logical operations

Fetch, decode, execute, store

Comparison op[erations, logical operations, arithmetic operations

The correct answer is "Fetch, decode, execute, store." This sequence of operations represents the basic steps in a machine cycle. The fetch operation retrieves an instruction from memory, the decode operation interprets the instruction, the execute operation carries out the instruction, and the store operation writes the result back to memory. These four operations are fundamental to the functioning of a computer's central processing unit (CPU).

5. The piece of equipment that interprets and carries out the basic instructions that operate a computer is called the _________________________.

The correct answer is CPU, Processor, Microprocessor. These terms are all used interchangeably to refer to the central processing unit of a computer. The CPU is responsible for executing instructions and performing calculations, making it the core component of a computer system. The processor and microprocessor are alternative names for the CPU, emphasizing its role in processing and executing instructions.
