Answer:NULL Scan
Explanation:RFC 793(Request for comments) is a type of RFC command labeled with the number 793 which can operate with the TCP protocol.They are sort of document form which is from IETF( Internet Engineering Task Force ).
The null scan is scanning protocol used by legal as well as illegal hackers for working in the transfer control protocol architecture. It is used for the identification of the the ports and holes in TCP servers.they can also have the negative impact if used by the illegal hackers.

Answer:
2^7= 128
Explanation:
An instruction format characterizes the diverse part of a guidance. The fundamental segments of an instruction are opcode and operands. Here are the various terms identified with guidance design: Instruction set size tells the absolute number of guidelines characterized in the processor. Opcode size is the quantity of bits involved by the opcode which is determined by taking log of guidance set size. Operand size is the quantity of bits involved by the operand. Guidance size is determined as total of bits involved by opcode and operands.
