Question 3

The ____ tries to predict what data and instructions will be needed and retrieves them ahead of time in order to help avoid delays in processing.

Accepted Answer

The role of the prefetch unit is to predict and retrieve data and instructions ahead of time, helping to avoid delays in processing. The control unit is responsible for controlling the overall operation of the CPU, the floating-point unit performs mathematical calculations involving decimal numbers, and the arithmetic/logic unit performs basic arithmetic and logical operations. None of these options are directly related to prefetching data.

Question 7

The ____ allows a core to communicate with other CPU components, such as the memory controller and other cores.

Accepted Answer

The bus interface unit (BIU) is the component of the CPU that allows communication between the core (execution unit) and other CPU components, such as memory and other cores. The control unit (CU) handles instruction fetching and decoding, while the prefetch unit (PFU) fetches instructions from memory before they are needed.

Question 8

Case-Based Critical Thinking Questions Case 2-1 Jess is a musician who has just bought a new computer. Now she need to figure out how to connect this computer to the devices that were connected to her old computer. Jess has pictures from her old computer saved on a flash memory card. To transfer these to her new computer, she will insert the card into a(n) ____.

Accepted Answer

Jess should insert the flash memory card into a slot on her new computer to transfer the pictures. A Flash memory card is typically inserted into a slot on a computer or a card reader to access its contents. SCSI port and IrDA port are not commonly used for transferring data between a computer and a flash memory card. A modem is used for connecting to the internet or other networks, and is not relevant in this case.

Question 9

One nanometer (nm) is ____ of a meter.

Accepted Answer

One nanometer is one-billionth of a meter, which means it is 0.000000001 meters.

Question 10

Case-Based Critical Thinking Questions Case 2-2 Jack has a computer at home that he uses to access the Internet, store and edit personal photos, and create and edit documents. Recently, he has come to realize that in order to keep the computer performing at its best, he needs to carry out regular system maintenance on the computer. Jack can speed up his computer by scanning it for viruses and ____.

Accepted Answer

The correct term is "spyware" which refers to malware that is designed to spy on the user's activities on their computer. Regular scans for spyware can help maintain the performance of the computer. Option A "mailware" is misspelled and does not exist as a term. Option B "utilities" is a general term and does not specifically refer to system maintenance. Option D "icons" are not related to system maintenance or performance.

Question 11

To synchronize all of a computer's operations, a ____, which is located on the motherboard, is used.

Accepted Answer

A system clock is a timing device located on the motherboard that synchronizes all computer operations. It generates pulses at a specific frequency to control the pace of operations and ensure that all components of the computer are coordinated. The other options listed are not directly related to synchronization of computer operations.

Question 12

One reason a computer might become inefficient is that when programs are uninstalled, pieces of the program are sometimes left behind or references to these programs are left in operating system files such as the ____.

Accepted Answer

When programs are uninstalled, pieces of the program or references to it may be left behind in the Windows registry, which can cause inefficiencies in the computer's operating system. The other options are not directly related to the issue of inefficient computers caused by remnants of uninstalled programs.

Question 13

The ____ is the section of a CPU core that performs arithmetic involving integers and logical operations.

Accepted Answer

ALU (Arithmetic Logic Unit) is the section of a CPU core that performs arithmetic involving integers and logical operations such as AND, OR, and NOT. FPU (Floating Point Unit) performs arithmetic involving decimal numbers, while the control unit manages the flow of data within the CPU and the decode unit interprets instructions from memory.

Question 14

Case-Based Critical Thinking Questions Case 2-2 Jack has a computer at home that he uses to access the Internet, store and edit personal photos, and create and edit documents. Recently, he has come to realize that in order to keep the computer performing at its best, he needs to carry out regular system maintenance on the computer. Jack can use the ____ program to locate and delete temporary files, such as installation files, Web browsing history, and files in the Recycle Bin.

Accepted Answer

Windows Disk Cleanup is the program that can be used to locate and delete temporary files such as installation files, browsing history, and files in the Recycle Bin. The Windows Registry is a database that stores configuration settings and options for the operating system and installed programs. Disk Defragmenter is a program that reorganizes files on a hard drive to improve performance. Temporary Files refer to files that are created and used by programs on a short-term basis and are usually deleted automatically when the program exits.

Question 15

Case-Based Critical Thinking Questions Case 2-1 Jess is a musician who has just bought a new computer. Now she need to figure out how to connect this computer to the devices that were connected to her old computer. To connect her external hard drive, in which all of her music files are stored, to the computer, Jess needs to use a ____.

Accepted Answer

Most modern computers come with USB ports which can be used to connect external hard drives. Serial ports are older technology and are not always included on new computers. A network antenna is used to connect to a network wirelessly, not to connect a hard drive directly to a computer. A modem cable is used to connect to the internet using a modem, again not to connect an external hard drive.

Question 16

The ____ takes instructions from the prefetch unit and translates them into a form that the control unit can understand.

Accepted Answer

The decode unit takes instructions from the prefetch unit and translates them into a form that the control unit can understand. This process is called instruction decoding.

Question 17

The ____ orders data and instructions from cache or RAM based on the current task.

Accepted Answer

The prefetch unit is responsible for ordering data and instructions from cache or RAM based on the current task, improving processing efficiency by fetching data before it is needed.

Question 18

Integrated circuits contain interconnected components such as _______________ that enable electrical current to perform particular functions.

Accepted Answer

The answer of Integrated circuits contain interconnected components such as...

Question 19

Case-Based Critical Thinking Questions Case 2-2 Jack has a computer at home that he uses to access the Internet, store and edit personal photos, and create and edit documents. Recently, he has come to realize that in order to keep the computer performing at its best, he needs to carry out regular system maintenance on the computer. Since Jack has a Windows system, he can right-click a hard drive icon in File Explorer, select Properties, and then select the ____ option on the Tools tab to check that hard drive for errors.

Accepted Answer

The correct option to check the hard drive for errors on a Windows system is the "Check" option on the Tools tab. The "Disk Defragmenter" option is used to organize files on the hard drive for quicker access, "Defragment now" is a shortcut to the Disk Defragmenter option, and "Windows Disk Cleanup" is used to free up space on the hard drive by deleting unnecessary files.

Question 20

Terascale computing is the ability of a computer to process one ____ floating point operations per second (teraflops).

Accepted Answer

Terascale computing refers to the ability of a computer to process one trillion floating point operations per second, which is equivalent to 10^12 or a trillion operations. The options A, B, and D are lower than the terascale level, so the best choice is C.
