### Character Data is represented by coding schemes, which use a series of 1s and 0s.

• A.

True

• B.

False

A. True
Explanation
Character data is indeed represented by coding schemes that use a series of 1s and 0s. This is commonly known as binary code, where each character is assigned a unique combination of 1s and 0s. This coding scheme allows computers to understand and process characters, such as letters, numbers, and symbols, by converting them into binary form. Therefore, the statement "Character Data is represented by coding schemes, which use a series of 1s and 0s" is true.

### A processor is typically the most important and the most expensive single component of a computer

• A.

True

• B.

False

A. True
Explanation
The given statement is true because a processor, also known as the central processing unit (CPU), is indeed the most important component of a computer. It is responsible for executing instructions, performing calculations, and managing the overall operation of the computer system. Without a processor, a computer cannot function. Additionally, processors are often expensive due to their complex design and advanced technology.

Rate this question:

• 3.

• A.

True

• B.

False

B. False
Explanation
Upgrading a computer's processor is not always inexpensive and easy. It can be a complex and costly process that may require additional hardware and technical expertise. Additionally, upgrading the processor alone may not significantly enhance the computer's performance if other components such as RAM or storage are not upgraded as well. Therefore, the statement is false.

### The _______ system uses 1s and 0s to represent data

• A.

Morse Code

• B.

Binary Number

• C.

ASCII

• D.

Data Representation

B. Binary Number
Explanation
The correct answer is Binary Number because the binary system is a numerical system that uses only two digits, 1s and 0s, to represent data. In this system, each digit represents a power of 2, allowing for the representation of complex data using a combination of these two digits. Morse Code, ASCII, and Data Representation are not specific to the use of 1s and 0s to represent data.

### _____ is a type of coding scheme used to represent character data.

• A.

ASCII

• B.

Unicode

• C.

EBCDIC

• D.

All of the above are examples

D. All of the above are examples
Explanation
The given question asks about the type of coding scheme used to represent character data. The correct answer is "All of the above are examples" because ASCII, Unicode, and EBCDIC are all examples of coding schemes used to represent character data. ASCII is a widely used coding scheme that represents characters using 7 or 8 bits, Unicode is a more comprehensive coding scheme that represents characters from various languages and scripts, and EBCDIC is a coding scheme primarily used in IBM mainframes. Therefore, all three options mentioned in the answer are examples of coding schemes used for character data representation.

### ______ is the world's largest chipmaker

• A.

Apple

• B.

IBM

• C.

AMD

• D.

Intel

D. Intel
Explanation
Intel is the world's largest chipmaker. They have been dominating the global semiconductor industry for many years, producing a wide range of computer processors and other electronic components. Intel's products are widely used in personal computers, servers, and other devices, making them a key player in the technology market. Their strong market presence, extensive research and development capabilities, and constant innovation have contributed to their position as the largest chipmaker in the world.

### Files you delete from your hard disk are sent to the windows _____.

• A.

Trash can

• B.

Transfer Station

• C.

Recycle Bin

• D.

None of the above; they are permanently deleted from the hard drive.

C. Recycle Bin
Explanation
When you delete files from your hard disk in Windows, they are not permanently deleted. Instead, they are sent to the Recycle Bin. The Recycle Bin acts as a temporary storage for deleted files, allowing you to restore them if needed. If you empty the Recycle Bin or permanently delete the files, then they are removed from the hard drive.

Rate this question:

### File size is usually measure in ___

• A.

Bytes

• B.

Kilobytes

• C.

Megabytes

• D.

Any of the above

D. Any of the above
Explanation
File size can be measured in bytes, kilobytes, or megabytes. The choice of unit depends on the size of the file. For smaller files, such as text documents or small images, bytes or kilobytes may be used. For larger files, such as videos or high-resolution images, megabytes or even gigabytes may be used. Therefore, any of the options provided can be used to measure file size depending on the context.

### RAM holds data in circuitry that's directly connected to the motherboard; whereas, the hard drive stores data on ___ media.

• A.

Volatile

• B.

Solid-State

• C.

Optical

• D.

Magnetic

D. Magnetic
Explanation
The correct answer is magnetic because hard drives use magnetic media, such as a spinning disk coated with a magnetic material, to store data. This allows for the data to be written and rewritten on the disk using magnetic fields. Unlike RAM, which is volatile and loses its data when power is lost, hard drives retain their data even when the power is turned off. Solid-state drives (SSDs) use flash memory instead of magnetic media, optical drives use laser technology, and volatile refers to the temporary nature of data stored in RAM.

### For good basic performance, a computer running Windows Vista should have at least ___ of RAM

• A.

512 MB

• B.

1 GB

• C.

2 GB

• D.

3 GB

B. 1 GB
Explanation
A computer running Windows Vista should have at least 1 GB of RAM for good basic performance. This amount of RAM allows the operating system to run smoothly and handle basic tasks efficiently. With 1 GB of RAM, the computer will have enough memory to handle multiple programs and tasks without experiencing significant slowdowns or performance issues.
