Clock rate or clock speed in computing typically refers to the frequency at which the clock generator of a processor can generate pulses used to synchronize the operations of its components. [1] It is used as an indicator of the processor's speed. Clock rate is measured in the SI unit of frequency hertz (Hz).
In PCs, the CPU's external address and data buses connect the CPU to the rest of the system via the "northbridge". Nearly every desktop CPU produced since the introduction of the 486DX2 in 1992 has employed a clock multiplier to run its internal logic at a higher frequency than its external bus, but still remain synchronous with it. This ...

YouTube TV is an American Internet Protocol television service operated by YouTube, a subsidiary of Google, which in turn is a subsidiary of Alphabet Inc. Announced on February 28, 2017, [2] the virtual multichannel video programming distributor offers a selection of live linear channel feeds and on-demand content from more than 100 television networks (including affiliates of the Big Three ...
This processor was a single-chip design, ran at a higher clock frequency than the R8000, and had larger 32 KB primary instruction and data caches. It was also superscalar, but its major innovation was out-of-order execution. Even with one memory pipeline and simpler FPU, the vastly improved integer performance, lower price, and higher density ...
In computer architecture, frequency scaling (also known as frequency ramping) is the technique of increasing a processor's frequency so as to enhance the performance of the system containing the processor in question. Frequency ramping was the dominant force in commodity processor performance increases from the mid-1980s until roughly the end ...
In February 2017, live streaming was introduced to the official YouTube mobile app. Live streaming via mobile was initially restricted to users with at least 10,000 subscribers, [67] but as of mid-2017 it has been reduced to 100 subscribers. [68] Live streams support HDR, can be up to 4K resolution at 60 fps, and also support 360° video. [49] [69]
