It is four octets of numbers from 0-255 represented in decimal form. Class A always has the first bit of their address set to 0. They have an 8 bit network mask that is why they leave it zero so they can have 7 bits for the network portion. They have 128 possible networks. Class B addresses always has the first bit set to 1 and their second bit set to 0.

NT 1210 Chapter 1 2. Which of the following terms means approximately 106 bytes? Megabyte 5. This chapter describes the concepts behind ho a CPU reads the content from RAM. Which of the following is true about the process of read data, as described in the chapter?
The advantages of using port expanders are that you get more ports to use. SAS expander’s takes one port and makes many out of them. So you have one 6gbps, and you expand it so you can connect 8 devices. The total throughput on all 8 ports is only 6gbps, or about 80MBPS. Even in regular hard drives can do 80 MBPS.
The IPv4 address space is 32 bits. 2^32 = 4,294,967,296 3. Approximately how many IPv6 addresses are possible? The IPv6 address space is 128 bits. 2^128 = 340,282,366,920,938,463,463,374,607,431,768,211,456 4.
