Question 1

The central processing unit is the same thing as the microprocessor.

Accepted Answer

The terms central processing unit (CPU) and microprocessor are often used interchangeably to refer to the main processor in a computer system.

Question 2

Which of the following is not an input device?&#10;A) Keyboard&#10;B) Touch Screen&#10;C) Camera&#10;D) Monitor

Accepted Answer

A monitor is not an input device. It is an output device that displays the output from an input device such as a keyboard or a touch screen.

Question 3

Registers in the CPU store large amounts of data and instructions for long periods of time.

Accepted Answer

Registers in the CPU are small amounts of memory that store data and instructions temporarily for fast access, but they do not store large amounts of data for long periods of time.

Question 4

Which of the following categories of general purpose computers is the lest expensive?&#10;A) Supercomputers.&#10;B) Midrange Computers&#10;C) Microcomputers&#10;D) Mainframe Computers

Accepted Answer

Microcomputers are the least expensive category of general purpose computers. They are commonly known as personal computers or desktop computers and are designed for individual use. They are widely available and affordable for most consumers.

Question 5

Mainframes are relatively large computers used by corporations for centralized data processing and maintenance of large databases.

Accepted Answer

Mainframes are indeed relatively large computers used for centralized data processing and maintenance of large databases by corporations.

Question 6

Thin-client systems are more complex than fat client systems.

Accepted Answer

Thin-client systems have less hardware and software requirements compared to fat client systems, making them simpler and easier to manage.

Question 7

Hardware is simply the computer itself.

Accepted Answer

Hardware refers to the physical components of a computer system, such as the CPU, memory, motherboard, hard drives, keyboard, and mouse, not just the computer itself.

Question 8

The central processing unit performs the actual computation or &#34;number crunching&#34; inside any computer.

Accepted Answer

The central processing unit (CPU) is responsible for executing instructions and performing calculations in a computer. It is considered the "brain" of the computer and is responsible for coordinating the activities of the other components. Therefore, it does perform the actual computation or "number crunching" inside any computer.

Question 9

The _____ is the number of bits that can be processed by the CPU at one time.&#10;A) clock speed&#10;B) word length&#10;C) bus width&#10;D) line width&#10;E) none of the above

Accepted Answer

Word length is the number of bits that can be processed by the CPU at one time. Clock speed refers to how many instructions can be executed in a second, bus width is the number of data lines that can be transferred at once, and line width is not relevant to the question.

Question 10

Decisions about hardware focus on which of the following factors?&#10;A) power&#10;B) appropriateness for the task&#10;C) speed&#10;D) cost&#10;E) all of the above

Accepted Answer

Decisions about hardware should take into consideration all of the above factors - power, appropriateness for the task, speed, and cost. Each factor is important and needs to be balanced in order to make the best decision for the specific situation. For example, a high-powered computer may be appropriate for a gaming setup, but may not be justified for basic office work due to its cost. Similarly, a low-cost computer may be appropriate for basic office work, but may not have enough power for more resource-intensive tasks. So, all of these factors should be considered together.
