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.

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.

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).

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.

HDD is an acronym for Hard Disk Drive. The term "drive" refers to the device that reads and writes data on a hard disk. Therefore, the correct answer is "Drive."

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.

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.

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.

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 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 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.

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.

AMD stands for Advanced Micro Devices.

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.
