1.ARM, MIPS, SPARC,CISC is a complex instruction set is the CISC, others are thin instruction set.

The 2.IP data header takes the () byte order, in this byte order, from the low address to the high address 0x1234 representation is (C).

• big_endian,0x12 0x34 0 0
• little_endian,0x34 0x12 0 0
• big_endian,0 0 0x12 0x34
• Little_endian, 0 0 0x34 0x12

Resolution: Big_endian: High in low address;

Small-endian: status in Low address

3. Host A and Host B has established a TCP connection, host A to Host B sent two consecutive TCP segments, respectively containing 300 bytes and 500 bytes of payload, the first segment of the serial number is 200, Host B correctly received two segments, sent to host a confirmed serial number is? D

• 500
• 700
• 800
• 1000

Parse: Confirm serial number = The length of the original serial number +TCP segment, so the first confirmation serial number is 200+300=500, the second confirmation serial number is 500+500=1000.
