A、Send 3000 TCP message segments before receiving an acknowledgement
B、Send 1000 bytes before receiving an acknowledgement
C、Send 3000 bytes before receiving an acknowledgement
D、Send 9000 TCP message segments before receiving a confirmation
喵查答案：Send 3000 bytes before receiving an acknowledgement
During the data transmission phase of a TCP connection, if the transmission window value of the sender changes from 2000 to 3000, it means that the sender can _ _ _ _ _ _ _ _.

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.
