A、10.0. 11.0/25
B、10.0. 11.0/26
C、10.0. 11.64/25
D、10.0. 11.4/26
喵查答案：10.0. 11.0/25
The IP address block assigned by a company to the personnel department is 10.0.11.0/27, the IP address block assigned to the planning department is 10.0.11.32/27, and the IP address block assigned to the Marketing Department is 10.0.11.64/26. Then the addresses of these three address blocks after aggregation are
-
Generally speaking, the higher the sound quality is required, the higher the quantization level and the lower the sampling frequency is. -
The higher the sampling frequency, the closer the discrete digitized sound wave is to its original waveform. -
Audio files in WAV format do not use compression algorithm, so they have good sound restorability, strong stereoscopic impression and relatively large file capacity. -
MPEG video compression standards include MPEG-1, MPEG-2, MPEG-4, MPEG-7 and MPEG-21.
