Question 2

Which of the following is a computer procedure that takes raw data and changes it into information?
A) RAM
B) IPOS
C) BIOS ROM
D) MP3

Accepted Answer

IPOS (Input-Process-Output-Storage) is a computer procedure that takes raw data as input, processes it, and produces meaningful information as output. RAM, BIOS ROM, and MP3 are not directly involved in this information transformation process.

Question 3

Case 1-1 Eli uses computers as part of his daily duties in his job as a store clerk at a department store. When Eli views the description and price of an item displayed on the computer monitor, which step in the information processing cycle is being performed?
A) Receiving data
B) Processing data
C) Outputting information
D) Storing data

Accepted Answer

Eli is viewing the description and price of an item displayed on the computer monitor, which is an example of outputting information. The other steps in the information processing cycle include receiving data (inputting), processing data, and storing data.

Question 4

The ____ coordinates all of the processor's activities.
A) arithmetic/logic unit (ALU)
B) control unit
C) random access memory (RAM)
D) expansion slot

Accepted Answer

The control unit is responsible for coordinating all of the processor's activities, including managing the flow of data between the processor and main memory, interpreting instructions, and managing the actions of other components within the CPU. The arithmetic/logic unit (ALU) performs arithmetic and logic operations, the random access memory (RAM) stores data and program instructions, and an expansion slot is a port on a computer motherboard where additional components can be attached for improved functionality.

Question 5

Which of the following system components is the brains of the computer?
A) Circuit board
B) CPU
C) Memory
D) Network card

Accepted Answer

The CPU (Central Processing Unit) is considered the brains of the computer as it performs most of the processing and calculations required for a computer to function. The circuit board, memory, and network card all play important roles in a computer's operation, but they do not have the same level of control and processing power as the CPU.

Question 6

Hard drives, magnetic tapes, and Zip disks are examples of ____.
A) magnetic storage devices
B) optical storage devices
C) solid-state storage
D) remote storage

Accepted Answer

A) DVD-ROM
B) DVD-R
C) DVD-RW
D) Blu-ray

Accepted Answer

Blu-ray provides more than five times the storage capacity of traditional DVDs and is considered the next-generation optical disc format. DVD-ROM, DVD-R, and DVD-RW are traditional DVD formats with lesser storage capacity than Blu-ray.

Question 8

FIGURE 1-1  What type of storage device is shown in Figure 1-1 above?
A) Magnetic storage device
B) Optical storage device
C) Solid-state storage

Question 9

What type of computer could be found in a digital watch?
A) Mainframe computer
B) Supercomputer
C) Embedded computer
D) Notebook computer

Accepted Answer

Embedded computers are low-cost, low-power devices, which are often used in small electronic devices such as watches, medical equipment, and appliances. Therefore, an embedded computer is the most likely type of computer found in a digital watch. The other options are not appropriate as mainframe and supercomputers are large-scale systems used for heavy-duty computing tasks, and a notebook computer is too big to fit in a watch.

Question 10

The more ____ you have, the faster the computer processes data.
A) ROM
B) RAM
C) I-cycles
D) E-cycles

Accepted Answer

RAM (Random Access Memory) is the type of memory that directly affects the processing speed of a computer. The higher the amount of RAM, the more data the computer can handle at once, which can result in faster processing speeds. ROM (Read-Only Memory) is non-volatile memory used to store permanent data, such as the computer's BIOS. I-cycles and E-cycles are not relevant terms in computer memory.

Question 11

Which of the following is NOT a safeguard you should take to care for removable storage media?
A) Keep away from magnetic fields.
B) Avoid extreme temperatures.
C) Only remove the media from a drive when the drive indicator light is on.
D) Keep the discs in a sturdy case when transporting.

Accepted Answer

This statement is not a safeguard for caring for removable storage media. Instead, it is important to eject the media properly from the drive. The other options are all important safeguards to protect the integrity and longevity of the media.

Question 12

Input, output, and processing devices grouped together represent a(n) ____.
A) mobile device
B) information processing cycle
C) circuit board
D) computer system

Accepted Answer

Input, output, and processing devices together make up a computer system. Mobile devices are a subset of computer systems and not inclusive of all three types of devices mentioned. The information processing cycle represents the order in which data flows through a computer system, but it is not a physical grouping of devices. Circuit boards are a component of a computer system, but they do not include all three types of devices mentioned.

Question 13

The ____ of a CD/DVD indicates its quality.

Question 18

Case 1-2 Myra is using a word-processing program to create an address list of her family and friends. If Myra wants to save her address list on solid-state storage media, which of the following would she choose?
A) CD-ROM
B) DVD-R
C) Magnetic tape
D) USB flash drive

Accepted Answer

A USB flash drive is a solid-state storage media that is small, portable, and easy to use. It is a popular choice for saving small files, including address lists. CD-ROM, DVD-R, and magnetic tape are not solid-state storage media, and they are not as convenient for saving small files as a USB flash drive.

Question 19

Case 1-2 Myra is using a word-processing program to create an address list of her family and friends. As Myra inputs the names, addresses, and telephone numbers, her data is stored in ____?
A) the control unit
B) RAM
C) a dual-core processor
D) BIOS ROM

Accepted Answer

The data that Myra inputs is temporarily stored in RAM, which stands for Random Access Memory. RAM is used to store data temporarily while the computer is running, and it is a volatile memory, meaning that its contents are lost when the computer is turned off or restarted. The control unit, dual-core processor, and BIOS ROM are all important components of a computer system, but they do not directly store user data like RAM does.

Question 20

____ is the process of obtaining a program instruction or data item from RAM.
A) Fetching
B) Decoding
C) Executing
D) Storing

Accepted Answer

The process of obtaining a program instruction or data item from RAM is called fetching. The other options, decoding, executing, and storing, refer to subsequent steps in the processing of the instruction or data item.
