A. 1 ......... Each piece of the ip address is limited to 255 because it is represented by one byte. There is really no limit to the number of addresses we could have, because we could simply add another byte onto the end. As it is, the addresses are comprised of 4 bytes, with a total of 256^4 possible values (4,294,967,296) There are many possible values, and a conspiracy here is not likely.

A. 2 ......... Each dot on the screen is represented by one byte in memory in such a system. This would mean 256 possible values. (Don't forget to count the zero!)

A. 3 ......... In ASCII, each character is stored in one byte, so 500 characters would be 500 bytes. Your editor might save tabs and document information in special ways, so your mileage might vary.

A. 4 ......... Roughly 720,000 bytes To be more precise, 720 * 1024 = 737,280 To figure the number of bits, multiply the bytes by 8: 737280 * 8 = 5,898,240
