You install a new 250 GB hard drive on your computer and format it. Upon checking the available space on the hard drive in My Computer, you are puzzled to find that there is substantially less space available than 250GB. Why?
- A.
Whoever you ordered it from lied to you.
- B.
Formatting tables and free space.
- C.
The hard drive is defective.
- D.
You incorrectly formatted the hard drive with an older formatting standard.
Correct Answer
B. Formatting tables and free space.Explanation
The reason for finding less available space on the newly installed and formatted 250 GB hard drive is due to formatting tables and free space. When a hard drive is formatted, a small portion of the total space is reserved for formatting tables and other system files. Additionally, the file system also takes up some space, further reducing the available capacity. Therefore, the actual usable space on the hard drive is always slightly less than the advertised capacity.Rate this question:

What is the most crucial component to any computer system?
- A.
Power Supply
- B.
RAM
- C.
Hard Drive
- D.
CPU
- E.
Motherboard
Correct Answer
D. CPUExplanation
The most crucial component of any computer system is the central processing unit (CPU). The CPU is often referred to as the "brain" of the computer because it performs the essential tasks of executing instructions, processing data, and managing the overall operation of the computer. It carries out arithmetic and logic operations, handles input and output, and coordinates the functioning of all the hardware and software components within the computer.Rate this question:

QPI and HyperTransport have all but replaced this in current hardware, but what used to be the single most important factor in overall system speed?
- A.
CPU
- B.
Memory
- C.
Front Side Bus (FSB)
- D.
Video Card
- E.
Hard Drive
Correct Answer
C. Front Side Bus (FSB)Explanation
The front side bus (FSB) used to be the single most important factor in overall system speed. The FSB is responsible for transferring data between the CPU and other components in the computer, such as the memory and the video card. It determines the speed at which these components can communicate with each other. However, with the advancements in technology, the FSB has been largely replaced by newer technologies like QPI and HyperTransport, which offer faster and more efficient data transfer.Rate this question:

What does BIOS stand for?
- A.
Basic Input Output System
- B.
Byte Integration Operations System
- C.
Basic Interconnect Operating System
- D.
Basic Integration Operations System
Correct Answer
A. Basic Input Output SystemExplanation
BIOS stands for Basic Input Output System. It is a firmware that is responsible for the initialization of hardware components during the booting process of a computer. It provides the necessary instructions for the computer to start up and load the operating system. BIOS also manages the communication between the operating system and the hardware devices attached to the computer.Rate this question:

Who invented the x86 standard?
- A.
IBM
- B.
AMD
- C.
VIA
- D.
Cyrix
- E.
Intel
Correct Answer
E. IntelExplanation
Intel is the correct answer because they were the ones who invented the x86 standard. The x86 standard refers to the set of instructions used in most personal computers and servers today. Intel developed the first x86 microprocessor, the Intel 8086, in 1978, and it became the foundation for subsequent x86 processors. The x86 architecture has since been widely adopted by other computer manufacturers, but it was Intel who initially created and popularized it.Rate this question:

What does the x stand for in AGP 8x?
- A.
Times the FSB Speed
- B.
Times the CPU Speed
- C.
Times PCI Speed
- D.
Times Graphics Speed
Correct Answer
C. Times PCI SpeedExplanation
The x in AGP 8x stands for "Times PCI Speed." AGP (Accelerated Graphics Port) is a type of interface used to connect graphics cards to a computer's motherboard. The number 8x refers to the data transfer rate of the AGP interface, which is eight times the speed of the PCI (Peripheral Component Interconnect) bus. Therefore, the x in AGP 8x represents the multiplication factor of the PCI speed.Rate this question:

Your computer suddenly shuts off and doesn't turn on after repeated attempts. What is the most likely cause?
- A.
CPU fried
- B.
Hard Drive crashed
- C.
CD-ROM fried
- D.
Power Supply blown
- E.
Motherboard fried
Correct Answer
D. Power Supply blownExplanation
The most likely cause for the computer suddenly shutting off and not turning on after repeated attempts is a blown power supply. A blown power supply can result in a loss of power to the computer, causing it to shut off and preventing it from turning back on. This can occur due to various reasons such as power surges, overheating, or aging of the power supply unit.Rate this question:

Why are SSDs superior to standard Hard Drive Technology?
- A.
Smaller
- B.
Near zero access times
- C.
No Moving Parts
- D.
Ruggedness
- E.
All of the above
Correct Answer
E. All of the aboveExplanation
SSDs (Solid State Drives) are superior to standard Hard Drive Technology for several reasons. Firstly, they are smaller in size, making them more compact and suitable for devices with limited space. Secondly, SSDs have near-zero access times, meaning data can be retrieved and written much faster than traditional hard drives. Additionally, SSDs have no moving parts, which reduces the risk of mechanical failure and increases their durability. Lastly, SSDs are generally more rugged and able to withstand shocks, vibrations, and extreme temperatures better than standard hard drives. Therefore, all of the above-mentioned factors contribute to the superiority of SSDs over traditional hard drives.Rate this question:

CPU Frequency (Mhz, Ghz) is the most important factor in overall CPU speed.
- A.
True
- B.
False
- C.
Can't say
- D.
None
Correct Answer
B. FalseExplanation
While frequency does influence the overall speed, the number of steps required to perform a cycle, the speed at which the CPU can access the RAM, and the amount of cache the CPU has govern the speed more than the frequency alone.Rate this question:

Who invented DOS?
- A.
Microsoft
- B.
Tim Paterson
- C.
Google
- D.
None of the above
Correct Answer
B. Tim PatersonExplanation
Tim Paterson is the correct answer because he is the creator of DOS (Disk Operating System). He developed the initial version of DOS, known as QDOS (Quick and Dirty Operating System), which later became the foundation for MS-DOS (Microsoft Disk Operating System). Microsoft acquired the rights to QDOS from Paterson and further developed it into MS-DOS, which became the dominant operating system for IBM-compatible personal computers in the 1980s and early 1990s.Rate this question:
