Which of the following characteristics relates to kerberos? a. a computer network authentication protocol that allows nodes communicating over a non-secure network to prove their identity to one another in a secure mannerb. a public interest research group in washington, d. c., established in 1994 to focus public attention on emerging civil liberties issues and to protect privacy, the first amendment, and constitutional values in the information agec. a round-robin database tool intended to handle time-series data like network bandwidth, temperatures, cpu load, and so on. d. dynamic random access memory (dram) that has a synchronous interface

You need to design a circuit that implements the functions in the following table: s0 s1 function0 0 a + 10 1 a – b1 0 a + b1 1 a – 1s0 and s1 are 1-bit control inputs to select the function of the circuit. inputs a and b are 4-bitnumbers in 2s complement form. the output is also a 4-bit number in 2s complement form.you are allowed to use only one ttl 7483 4-bit adder to implement all the functions. but anynumber of other components (except the adder) can be used.hint: design a combinational logic circuit to modify the input b and the “carry input” of theadder depending on the control inputs s0 and s1.important: lab grade will depend on the working of the circuit & will be checked of by your labinstructor.1. is the output valid for the following input combinations: a. s0 = 0, s1 = 0, a = 7, b = 3? b. s0 = 0, s1 = 1, a = 7, b = 3? c. s0 = 1, s1 = 0, a = -4, b = -5? d. s0 = 1, s1 = 1, a = -8, b = 6? 2. what is the range of inputs (for both a and b) that will produce the valid output for all the functions?
