The power supply supplies power to what parts of the computer?
Correct Answer
D. All of the above
Explanation
The power supply is responsible for supplying power to various components of the computer. This includes the motherboard, which is the main circuit board that connects and controls all the other components. It also supplies power to the drives, such as the hard drive and optical drive, which are essential for storing and accessing data. Additionally, the power supply may also provide power to some expansion cards, which are additional components that can be added to enhance the computer's functionality. Therefore, the correct answer is that the power supply supplies power to all of the above-mentioned parts of the computer.
2.
The central processing unit is also called what?
Correct Answer
A. Microprocessor
Explanation
The central processing unit (CPU) is often referred to as a microprocessor. This is because the microprocessor is the key component of the CPU that carries out the instructions of a computer program by performing basic arithmetic, logical, control, and input/output (I/O) operations. The CPU is responsible for executing instructions and coordinating the activities of all the other hardware components in a computer system. Therefore, the term microprocessor is synonymous with the central processing unit.
3.
Which level cache memory within the CPU is the slowest?
Correct Answer
B. Level 2
Explanation
The CPU's level 1 cache memory is located inside of the CPU. Level 2 cache memory is further away and slower than level 1 cache memory.
4.
What is #5 in the picture called?
Correct Answer
C. Case Fan
Explanation
#5 in the picture is called a case fan. It is a component that helps to cool the computer's case by circulating air and preventing overheating. The other options, CPU and Drive Bays, refer to different parts of the computer and are not applicable to the given image. Therefore, the correct answer is Case Fan.
5.
What part is located at the # 6 in the picture?
Correct Answer
C. Motherboard
Explanation
In the given question, the correct answer is "motherboard". The motherboard is a crucial component of a computer system that houses various other components such as the CPU, microprocessor, and chipset. It provides the electrical connections and communication between these components, allowing them to work together effectively. In the provided picture, the part located at #6 is most likely the motherboard as it is the main circuit board that holds and connects all the other components of a computer system.
6.
The four steps; fetch, decode, execute, and store are what's called the __________ __________of the computer.
Correct Answer
machine cycle
Explanation
The four steps; fetch, decode, execute, and store are what's called the machine cycle of the computer. This refers to the sequence of operations that a computer performs to fetch instructions from memory, decode them, execute the instructions, and store the results back in memory. The machine cycle is a fundamental concept in computer architecture and is repeated continuously to execute programs and perform tasks.
7.
When the computer is first turned on (or booted) the ____________ program is in control.
Correct Answer
BIOS
Basic Input Output System
Explanation
When a computer is first turned on or booted, the BIOS (Basic Input Output System) program takes control. The BIOS is responsible for initializing and testing hardware components, loading the operating system, and providing basic input and output functions for the computer. It acts as an intermediary between the hardware and software, ensuring that the computer starts up properly and is ready for operation.
8.
What part of the computer is located at #1 on the picture?
Correct Answer
B. BIOS
Explanation
The part of the computer located at #1 on the picture is the BIOS. The BIOS, which stands for Basic Input/Output System, is a firmware that is responsible for initializing and booting up the computer system. It is stored on a chip on the motherboard and provides the necessary instructions for the computer to start up and load the operating system. The BIOS also manages the communication between the hardware components of the computer and the operating system.
9.
Which part of the computer is rated by how many bits of information they can receive in one second?
Correct Answer
B. Modem
Explanation
A modem is the correct answer because it is a device that allows computers to connect to the internet. It is rated by how many bits of information it can receive in one second, which is commonly referred to as its data transfer rate. The higher the data transfer rate, the faster the modem can receive and transmit data. Memory, microprocessor, drive bay, and motherboard are all important components of a computer, but they are not specifically rated by how many bits of information they can receive in one second.
10.
Which card, located within the computer, has its own processor?
Correct Answer
D. Both A and B
Explanation
Both the video card and sound card, located within the computer, have their own processors. The video card, also known as a graphics card, has a dedicated processor called a GPU (Graphics Processing Unit) that handles the rendering and display of visual information. Similarly, the sound card has its own processor called a DSP (Digital Signal Processor) that processes audio signals and produces sound output. Therefore, both A (video card) and B (sound card) have their own processors.
