There are 250 2-address instructions. There are only a total of 256 2-address instructions allowed if we have 32-bit instructions (two addresses take up 24 bits, leaving only 8 bits for the opcode). Looking at the 8 bit opcode, assume bit patterns 00000000 (0) through 11111001 (249) are used for the 250 two-address instructions. Then there are 6 bit patterns left for one address instructions. However, each one of these can use the remaining 12 bits gained from having only one operand, so we have 6 * 212. 00000000 11111001 11111010 11111010 ... 11111111 11111111 ______________________________________________________________________________ xxxxxxxxxxxx xxxxxxxxxxxx 000000000000 111111111111 000000000000 xxxxxxxxxxxx 111111111111 xxxxxxxxxxxx xxxxxxxxxxxx xxxxxxxxxxxx xxxxxxxxxxxx xxxxxxxxxxxx 250 2-address instructions 212 212 6 * 212 1-address instructions

How are IP addresses assigned from a pool of IP addresses?
That means that the DHCP server keeps track of what IP addresses - out of a pool (or set) of addresses - have been assigned. Any time a host (computer or similar) requests an IP address, the DHCP server will assign an available address and mark it, in its memory, as "assigned" so it won't assign the same address to another computer.That means that the DHCP server keeps track of what IP addresses - out of a pool (or set) of addresses - have been assigned.

What is the purpose of including the destination address and source address fields in an ethernet frame?
Destination address is used to identify the recipient. Thus, a switch can send the frame out the correct port, and the receiving computer can confirm that the frame is for that computer and not for any other computer.Source address allows the receiving computer to know where to send the reply. It also helps a switch learn MAC addresses (learn which MAC addresses are connected to which switch ports).Destination address is used to identify the recipient.
