One of the storage principles _ storage

roughly how a basic SRAM chip works. SRAM is the abbreviation for "Static RAM", which is named because it does not disappear when the data is deposited (unlike DRAM dynamic random memory, which must be refreshed in a certain amount of time to keep the data stored therein). An SRAM unit is usually composed of 4-6 transistors, and when the SRAM cell is given a state of 0 or 1, it retains that state until the next time it is given a new state or the power is off before it changes or disappears.

have been added, representing 1000 of the 7-and 8-time parties. This is the current largest unit prefix.Then there are big and small. When we want to express a smaller number, we need to have a prefix in another direction.For example, M is 1000 minus 1 times, or 1 per thousand. MM is our usual millimeter, and MS is milliseconds. These are also the areas that people can perceive directly, so they are determined very early.Later in 60, the micro-prefix was determined, which is called "micro" in C

What is SD, HD, and full HD in monitoring?

. The two most important HDTV standards defined by SMPTE are smpte296m and smpte274m. The resolution defined by smpte296m (hdtv720p) is 1280x720 pixels, a high fidelity color in the 16:9 format, and a 25/30 hertz (HZ) Sequential Scan Frequency, that is, 25-30 frames per second, depending on the country, it also supports 50/60Hz scan frequency (50/60 frames per second ). Smpte274m (hdtv1080) defines a resolution of 1920x1080 pixels, a high fidelity col

Spectrum Analyzer RBW&VBW

The structure of frequency sweep spectrum analyzer Effects of RBW (Resolution Bandwidth) The RBW dictates the resolution bandwidth, which is related to the minimum bandwidth detectable by the instrument. The smaller the bandwidth, the more spectral resolution. However, there is a trade-off between what quickly the display can update the full frequency span under consideration and T He frequency resolution, which is relevant for distinguishing frequency, which is close together. For a swept-tune

Analog frequency vs. Digital frequency

In the study of digital signal processing, many newly-started friends often confuse the analog frequency, the digital frequency and the relationship between them, even some friends who have some knowledge of digital signal processing are puzzled by this problem.The frequency we normally refer to is the analog frequency, in hertz (Hz), or 1/s (1/s), in the case of no particular indication, and the mathematical notation is expressed in F. This is becaus

degrees. Grad represents the Gradians degree of the angle. A complete circle for the grad. Rad represents the Radian of the angle. A complete circle is 2π (about 57.29rad). Turn indicates a long circumference. A full circle is 1turn. Each of these units has a positive negative value indicating a clockwise or counterclockwise direction. In the following example, it is shown how to represent a clockwise 90 degree in various units. . foo { /* going clockwise * /transform:rotate (90deg);

About writing, the British 19th century famous essayist Hezrit said such a passage: As a writer, I tried to use the ordinary words and the familiar language structure, just as if I were a trader, I must use the common measure of the same, the words like money, the more general the better, and, They can only circulate and have value only by the approval of customs.Hezrit has been using this standard to guide his writing, and strive to use plain, straightforward, easy-to-understand words to expres

Introduction to % CPU in the ps command in Linux Shell

In the ps command, % CPU refers to the percentage of CPU usage time of a process. What does it mean? The man manual of PS is explained as follows: CPU utilization of the Process in "##.. #" format. Currently, it is the CPU time used divided by the time the process has been running (cputime/realtime ratio ),Expressed as a percentage. It will not add up to 100% unless you are lucky.
