- converting analog signals to digital signals
- 1. On a class B network, how many hosts are available at each site with a subnet mask of 248?
Options- A. 16,382
- B. 8,190
- C. 4,094
- D. 2,046
- E. 1,022 Discuss
- 2. Which of the following statement is incorrect?
Options- A. The Addresses Resolution Protocol, ARP, allows a host to find the physical address of a target host on the same physical network, given only the target IP address.
