Score:100%<\/p>\n
Points:100\u00a0out of 100<\/p>\n
Question 1<\/p>\n
Points:\u00a010\u00a0out of 10<\/p>\n
What is a system unit?<\/p>\n
\u00a0a circuit board to which many electronic components are attached<\/p>\n
\u00a0a component of the processor that directs and coordinates most computer operations<\/p>\n
\u00a0a device that interprets and carries out the basic instructions used to operate the computer<\/p>\n
\u00a0a case containing the electronic components of the computer used to process data<\/p>\n
Feedback<\/p>\n
Correct. The system unit consists of the case and the internal components used to process data into information.<\/p>\n
Question 2<\/p>\n
Points:\u00a010\u00a0out of 10<\/p>\n
What are the two main components of the central processing unit (CPU)?<\/p>\n
\u00a0the memory chips and memory slots<\/p>\n
\u00a0the control unit and arithmetic logic unit<\/p>\n
\u00a0the chip and the system clock<\/p>\n
\u00a0the expansion slots and motherboard<\/p>\n
Feedback<\/p>\n
Correct. The control units retrieves instructions and returns results to memory. The arithmetic logic unit processes data into information.<\/p>\n
Question 3<\/p>\n
Points:\u00a010\u00a0out of 10<\/p>\n
RAM is a form of<\/p>\n
\u00a0non-volatile memory<\/p>\n
\u00a0volatile memory<\/p>\n
Feedback<\/p>\n
Correct. The data stored in RAM is lost when the computer is turned off.<\/p>\n
Question 4<\/p>\n
Points:\u00a010\u00a0out of 10<\/p>\n
The function of the system clock is to:<\/p>\n
\u00a0speed up retrieval of data from the hard drive<\/p>\n
\u00a0control the timing of all computer operations.<\/p>\n
\u00a0display the date and time.<\/p>\n
\u00a0control the refresh rate of the monitor<\/p>\n
Feedback<\/p>\n
Correct. The system clock works with the CPU to regulate the speed at which data is retrieved and processed within the CPU.<\/p>\n
Question 5<\/p>\n
Points:\u00a010\u00a0out of 10<\/p>\n
Which component controls the timing of all computer operations?<\/p>\n
\u00a0the system clock<\/p>\n
\u00a0the ALU<\/p>\n
\u00a0the memory modules<\/p>\n
\u00a0the CPU<\/p>\n
Feedback<\/p>\n
Correct. The system clock is the quartz crystal circuit that controls the timing of computer operations.<\/p>\n
Question 6<\/p>\n
Points:\u00a010\u00a0out of 10<\/p>\n
What is the purpose of a port?<\/p>\n
\u00a0Ports are used to interpret and coordinate all signals in the computer.<\/p>\n
\u00a0Ports are used to join a cable to a peripheral.<\/p>\n
\u00a0Ports provide high-speed storage locations for sensitive data.<\/p>\n
\u00a0Ports provide memory locations for video and audio files.<\/p>\n
Feedback<\/p>\n
Correct. Ports are on the outside of the computer case. Cables and cords are plugged into ports. Peripherals such as USB devices are connected to the computer through ports.<\/p>\n
Question 7<\/p>\n
Points:\u00a010\u00a0out of 10<\/p>\n
The\u00a0, sometimes called the system board, is the main circuit board of the system unit.<\/p>\n
Feedback<\/p>\n
Correct. The term \u201cmotherboard\u201d is used to reference the primary circuit board in the computer, much in the way \u201cmotherlode\u201d and \u201cmothership\u201d refer to primary components in those contexts. Other circuit boards that attach to the motherboard are sometimes called \u201cdaughterboards.\u201d<\/p>\n
Question 8<\/p>\n
Points:\u00a010\u00a0out of 10<\/p>\n
Which of the following is true?<\/p>\n
\u00a0Nonvolatile memory is temporary.<\/p>\n
\u00a0The contents of nonvolatile memory are lost when the computer\u2019s power is turned off.<\/p>\n
\u00a0The contents of volatile memory are lost when the computer\u2019s power is turned off.<\/p>\n
\u00a0Volatile memory is permanent.<\/p>\n
Feedback<\/p>\n
Correct. \u201cVolatile\u201d means changeable, and volatile memory is erased when the power is turned off.<\/p>\n
Question 9<\/p>\n
Points:\u00a010\u00a0out of 10<\/p>\n
An external component such as a mouse, monitor, or printer is called a\u00a0<\/p>\n
Feedback<\/p>\n
Correct. A peripheral is an external component that attaches to the system unit via cables, cords, or USB-type connectors.<\/p>\n
Question 10<\/p>\n
Points:\u00a010\u00a0out of 10<\/p>\n
If you often play the latest computer games on your PC, which of the following would you consider the most critical components of the PC?<\/p>\n
\u00a0the weight and size of your PC<\/p>\n
\u00a0sophisticated graphics and sound adapter cards<\/p>\n
\u00a0processor speed and amount of RAM<\/p>\n
\u00a0A and B<\/p>\n
\u00a0B and C<\/p>\n
Feedback<\/p>\n
Correct. In order to fully enjoy video games, appropriate graphics and sound cards are needed along with adequate speed and RAM for processing.<\/p>\n
