An arrow goes from the laptop to a server, and is labeled as "30 ms". However, CAS latency (e.g. Aren't there two possible ways like either light or no light or do they use fixed intensities of the light to represent the 1 and 0? document.write(new Date().getFullYear())Vectorize images. 6. On the other hand, RAM latency refers to how quickly it can begin the operation. Direct link to KLaudano's post A bit is a single binary , Posted 3 years ago. Real-time. False 13. Nanosecond Definition & Meaning - Merriam-Webster Could a subterranean river or aquifer generate enough continuous momentum to power a waterwheel for the purpose of producing electricity?

The main reason for this is the accuracy of the PCs crystal oscillator (regardless of frequency), which is driving the clock circuitry. The second block is colored black and labeled 0. . Latency is therefore a fundamental measure of the speed of memory: the less the latency, the faster the reading operation. That said, it is possible to improve system performance by using newer, faster and more efficient memory. An example of the use of these measures is that if your CPU clock speed is 3.5 Mhz (Megahertz per Second)=285.71428571429ns(p) (ns=nanoseconds). The difference between the perception of latency and the truth of latency comes down to how latency is defined and measured. How is it possible to measure in nanoseconds? A RAM module's latency is determined by CL and also by the duration of each clock cycle, which is measured in nanoseconds. Also, I'd like to know about the ways this ns precision is already (sometimes) achieved. When deciding what memory to use in your computer, the speed measured in MHz is generally the more important number to consider. The middle third is empty and is labeled 0. These CPU processes could easily drive times up to milliseconds, he said. nanogram, nanometre, etc.) By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. This computer-engineering-related article is a stub. For instance, where multiple core processors are sharing the same cache, "each one could be stealing cache from the other, which then causes more CPU cycles." These modules include self-service utilities to cut down recourse to human assistance. FAQ | Terms & conditions | Privacy policy | Contact | Donate | Deals. Advertisement Advertisement On the other hand, RAM latency refers to how quickly it can begin the operation. If the data are not in the processor's cache, it takes longer to obtain them, as the processor will have to communicate with the external memory cells. How does speed of light become an obstacle to the latency? Many computer operations, such as the speed of memory chips, are measured in nanoseconds. Latency in this context is referring to the time it takes between your device sending a request to an external resource and that external resource responding. The two smaller units of the Processor are CU and ALU. The latency (also called the ping rate) was just.
