Bit rate is the number of digits transmitted per unit time during data transmission. Generally, the unit is kbps, that is, kilobytes per second. A more general understanding is the sampling rate. The larger the sampling rate per unit time, the higher the accuracy. The closer the processed file is to the original file, that is, the richer the image details. But the file volume is proportional to the sampling rate, that is, the higher the bit rate, the

If the value of the%idle is high but the system responds slowly, it is possible that the CPU waits for the allocated memory, at which time the memory capacity should be increased3. If the value of%idle is consistently below 1, the system's CPU processing power is relatively low, indicating that the most needed solution in the sys
