Questions and Answers

1.

What does the CPU stand for?
- A.
  
  Central Processed Units
- B.
  
  Central Processing Unit
- C.
  
  Camera Processor Unit
- D.
  
  Central Process Unit
Correct Answer
B. Central Processing Unit

Explanation
The correct answer is "Central Processing Unit". CPU stands for Central Processing Unit, which is the main component of a computer that performs most of the processing inside the computer. It is responsible for executing instructions and performing calculations, making it the "brain" of the computer.

RAM is long-term storage
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
The given statement is incorrect. RAM (Random Access Memory) is not long-term storage. It is a type of computer memory that is used for temporary storage of data that is actively being used by the computer's processor. RAM is volatile, meaning that its contents are lost when the computer is powered off or restarted. Long-term storage is typically provided by devices such as hard drives or solid-state drives (SSDs).

What is Refresh Rate?
- A.
  
  How many times your screen refreshes in one second
- B.
  
  How many frames your screen displays per second
- C.
  
  How many frames your screen can refresh in a second
- D.
  
  How many times your screen can upload in a second
Correct Answer
A. How many times your screen refreshes in one second

Explanation
The refresh rate refers to the number of times your screen refreshes or updates the displayed image in one second. A higher refresh rate means a smoother display and reduced motion blur.

The brains of a computer is also known as the CPU
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The CPU, or central processing unit, is indeed considered the brain of a computer. It is responsible for executing instructions, performing calculations, and coordinating the activities of all the hardware components. Just like the brain controls and processes information in the human body, the CPU controls and processes data in a computer. Therefore, the statement "The brains of a computer is also known as the CPU" is true.

What does ‘K’ mean on Intel processors?
- A.
  
  Locked
- B.
  
  Hyperthreading
- C.
  
  Integrated Graphics
- D.
  
  Unlocked
- E.
  
  Low-Power
Correct Answer
D. Unlocked

Explanation
The letter 'K' on Intel processors refers to the processor being "Unlocked." This means that the multiplier on the processor can be adjusted, allowing for easier overclocking and potentially higher performance. Overclocking involves running the processor at a higher speed than its default setting, which can result in improved performance but also increased heat generation. Unlocked processors are typically preferred by enthusiasts and gamers who want to push their hardware to its limits.

Simultaneous Multi-Threading (SMT) and Hyperthreading are the same
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Simultaneous Multi-Threading (SMT) and Hyperthreading are indeed the same. Both SMT and Hyperthreading refer to the technology that allows a single physical processor core to execute multiple threads simultaneously. This technology improves overall system performance by maximizing the utilization of the processor's resources. In essence, SMT and Hyperthreading enable the processor to handle multiple tasks concurrently, resulting in better multitasking capabilities and increased efficiency. Therefore, it is accurate to say that SMT and Hyperthreading are synonymous terms for the same concept.

What is CPU Clock Speed normally measured in?
- A.
  
  MPH
- B.
  
  MHz
- C.
  
  GHz
- D.
  
  Kts
Correct Answer
C. GHz

Explanation
CPU Clock Speed is typically measured in GHz (gigahertz). This unit represents the number of cycles per second that a CPU can execute. A higher clock speed indicates that the CPU can perform more instructions in a given amount of time, resulting in faster processing speed. Therefore, GHz is the correct unit for measuring CPU Clock Speed.

SSDs are slower than HDDs
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
This statement is false. SSDs (Solid State Drives) are actually faster than HDDs (Hard Disk Drives). SSDs use flash memory to store data, which allows for faster read and write speeds compared to the spinning disks used in HDDs. Additionally, SSDs have no moving parts, which reduces access times and improves overall performance. Therefore, SSDs are considered to be faster than HDDs.

What is internet speed measured in?
- A.
  
  MB/s
- B.
  
  Mbps
Correct Answer
B. Mbps

Explanation
Internet speed is measured in Mbps, which stands for megabits per second. Mbps is a unit of measurement that represents the amount of data that can be transmitted over the internet in one second. It is commonly used to quantify the speed of internet connections, indicating how quickly data can be downloaded or uploaded. The "M" in Mbps refers to megabits, which is a unit of digital information, while the "bps" stands for per second. Mbps is a widely recognized and used unit for measuring internet speed.

What is download speed (downloading a file) measured in?
- A.
  
  Mbps
- B.
  
  Megabyte
- C.
  
  MB/s
- D.
  
  Megabit
Correct Answer
C. MB/s

Explanation
Download speed is typically measured in Megabits per second (Mbps). However, the correct answer in this case is MB/s (Megabytes per second). While Mbps is commonly used to measure internet speed, MB/s is a more accurate representation of the speed at which a file is downloaded. This is because file sizes are usually measured in Megabytes (MB), and the speed at which the file is downloaded is measured in seconds. Therefore, the correct answer is MB/s.

TB (Terabyte) is bigger than Petabyte (PB)
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
The statement is incorrect. A terabyte (TB) is smaller than a petabyte (PB). In the International System of Units (SI), each unit is 1000 times larger than the previous one. Therefore, a petabyte is equal to 1000 terabytes.

GPU stands for ______ ______ ______

Correct Answer
Graphics Processing Unit

Explanation
GPU stands for Graphics Processing Unit. It is a specialized electronic circuit that is designed to rapidly manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display device. GPUs are commonly used in gaming and graphics-intensive applications to render and display high-quality graphics and images in real-time. They are also utilized in various fields such as scientific research, artificial intelligence, and cryptocurrency mining due to their parallel processing capabilities and high computational power.
