Best Answer

A clock cycle is the low-hi-low transition of the clock. On each transition, the processor executes an instruction. It determines the speed if execution. So

the faster the clock runs, the faster the chip works. This is why a Pentium 1 GHz

chip is a LOT faster than a Pentium 100 MHz chip.

Its unit is in Hz (or s-1) because it is a factor of frequency...

What is more a GB or a ghz?

A gb and a ghz are completely different things. A gb is a measure of the memory of a computer and ghz is a measure of frequency and is used to measure your procesor's clock speed.


What is the clock rate of a laptop?

Laptops do not have a specific clock speed. The clock speed of the specific processor that is in the laptop determines the clock rate of the computer. For example, my computer runs at a clock speed of 2 GHz. Some computers even have clock speeds close to 4 GHz.


What is Core Clock in computers?

Core clock is the actual speed at which the graphics processor on a video card on a computer operates. The core clock speed is measured in megahertz.


Is the clock speed a measure of how quickly a computer completes basic computations and operations?

Yes, but it is not the only measure, so it's best to take it with a pinch of salt. Some processors take more clock cycles to compute instructions than others.


What does it mean when a computer has a speed of 2.5ghz?

That's the speed the clock inside the Central Processor Unit operates. The faster the clock - the more operations per second the computer can perform.


What is the pace of a system clock on a computer measured by?

The unit of measurement used to measure a computerâ??s clock speed is called a hertz, A computerâ??s clock speed is normally measured in megahertz or gigahertz. A megahertz is one million ticks per second and one gigahertz is one billion ticks per second.


Are picoseconds used to measure the speed of 5th gen computers?

Picoseconds (ps) are a unit of time that are used to measure very short periods of time, and they are typically used to measure the speed of electronic devices and processes that operate at very high speeds, such as computer processors and other electronic components. However, it is not common to use picoseconds to measure the speed of computers. Instead, computer speed is usually measured in terms of the number of instructions that a computer can execute per second, which is typically expressed in units of hertz (Hz) or gigahertz (GHz). For example, a 5th generation computer might be described as having a clock speed of 3.5 GHz, which means that it can execute 3.5 billion instructions per second. The clock speed of a computer is determined by the speed at which the computer's processor (CPU) can operate, which is typically measured in GHz. The clock speed of a processor determines how quickly it can perform various tasks, such as executing instructions in a program or accessing data from memory. It's worth noting that the term "5th generation computer" is not a well-defined term, and it does not refer to any specific generation of computer technology. Different sources may use the term "5th generation computer" to refer to different types of computers or computer technologies.


Is the speed of computer is its strength?

The speed of a computer is one of its strengths. However, the clock speed of the processor chip is not a direct indicator of a particular computer's strength in comparison to others. For instance, a computer might have a lower clock rate in MHz but have more efficient instructions, enabling it to outperform a faster computer. The machine with the slower clock rate might also use faster memory as well.


If clock speed increases then what happens to processor speed?

Th clock speed is the processor speed. It is simply the amout of operations the processor can do per second. However if the processor has multiple cores, it will be as fast as number of cores * clock speed. Note that the processor speed is not the overall computer speed.

Is system clock the heart of computer?

No, the system clock is not the heart of the computer but the micro-processor. The basic characteristics that differentiate the micro-processors includes the instruction set, bandwidth, and the clock speed.
