1/3,000,000,000th of a second. One three-billionth of a second. Isn't that staggering? A Hertz is a frequency that measures per-second frequency. A Kilohertz (Hardly used) is 1,000Hz, a Megahertz (Not used often in computing anymore) is 1,000,000Hz, and a Gigahertz (Hello today's computers) is 1,000,000,000Hz.
It blows my mind that numbers like this are possible, how about you?
The clock cycle time for the processor in this system is the duration it takes for one complete cycle of the clock signal, determining the speed at which the processor can execute instructions.
The time to execute a 3 clock cycle instruction in a 25MHz processor is 120ns. One clock cycle is 40ns, 1/25Mhz, so three of them are 120ns.
a clock cycle is how long it take for the computer to complete one clock. this is different to every processor due to different speeds, single-, duel-, multi- and quad-cores, hyperthreadding etc.
A clock cycle is a unit of time in a computer system that regulates the speed at which the processor executes instructions. It impacts performance by determining how quickly the processor can process data and perform tasks. A faster clock cycle allows the processor to complete more instructions in a given amount of time, leading to improved performance.
This doesn't really math out properly. A 1.9GHz processor is a 1.9GHz processor. It can be the EQUIVILENT of a higher clock-rate, lower instructions per cycle processor, but it isn't the same, or "equal" at different clock speeds.
The difference between 2.66 dual core processor, and 64-bit dual core processor, is really two different processor specifications. 2.66 is actually 2.66Ghz, which is the clock speed of the processor. The clock speed tells you how many times the processor can execute instructions per second. A dual core processor is a processor with two cores on one die. This can be thought of as having two processors in one. The bit specification of a processor tells you how many binary instructions a processor can execute per clock cycle. Most processors today are 32-bit (32 binary instructions per clock cycle) or 64-bit (64 binary instructions per clock cycle). More RAM can be used with a 64-bit processor. A 32-bit processor is limited to addressing 4 Gigabytes of RAM, while a 64-bit process can address (theoretically) 16 Exabytes of RAM.
One limitation of a 16 bit processor, compared to a 64 bit processor, is computing speed. A 16 bit process can process 2 bytes (8 bits = 1 byte) of information per clock cycle. While a 64 bit processor can process 8 bytes of information per clock cycle, making the 64 bit processor four times faster than a 16 bit processor.
The most gaping advantage can be very easilly explained through example: Single core processors have a single thread, and can process a single set of instructions per clock cycle. This looks like this (Saying this processor can process 2 instructions a clock): (Note this is in an optimal setting where data is perfectly threaded) Clock 1: Instruction 1; Instruction 2; Clock 2: Instruction 3; Instruction 4; Clock 3: Instruction 5; Instruction 6; Clock 4: Instruction 7; Instruction 8; Dual-Core processing would do this same instruction set much quicker: Clock 1: Instruction 1; Instruction 2; Instruction 3; Instruction 4 Clock 2: Instruction 5; Instruction 6; Instruction 7; Instruction 8 In a perfectly threaded application, two equivilent-performance cores on a dual core processor would power through the work twice as quickly as a single-core model. A quad-core with these specs would do the entire instruction set in a single clock. Even if it isn't always a 2x increase, multiple-core procesors have a distinct advantage in a very large range of applications.
Cva:As bus cycle is not mentioned, hence assumed that bus cycle = clock rate = 250MHz.Duration of each bus cycle = 1 / 250M = 4ns; Please, correct me if I am wrong.
The clock period is the time duration of one clock cycle. For a clock frequency of 1 GHz (1 billion hertz), the clock period would be 1 nanosecond (1/1,000,000,000 seconds).
A Hz is a measure of cycles per second. 25 MHz is 25,000,000 Hz. So divide 1 second by 25,000,000 to find the length of a clock cycle. 1/25000000 = 4.0e-8 seconds / cycle
AnswerThe internal is located inside your computer. If your running Windows, the time it keeps is display on the lower right side of the screen. An external clock is usually located on another system and can be accessed with software. You can get software to sync your internal clock to that other system. The National Institute for Science and Technology (NIST) hosts a clock that many computer users and businesses sync to.Wow...can that answer be any more wrong?Internal and External clocks are NOT referring to the "time of day" type clocks, they refer to the internal processor clock cycle or an external clock source. The clock cycle of a processor is the time it takes for the processor to execute a data instruction (very basic explanation there) and is measured as the speed of a processor, like a 2.6gHz processor can execute 2.6 billion clock cycles per second.Now this is somewhat misleading as the processor speed itself is probably only 400MHz, but using an External Multiplier (clock multiplier, external clock), you increase the total amount of data the processor can execute in one clock cycle.This is a VERY basic example and I don't have time to really go deep, so it's best to search for a more concise answer if you really require one.
