In the videos we show that shortest job first is the best algorithm with respect to average turn around time when there is no input output (i/o) burst. when there is i/o bust we have three variants: shortest remaining burst time first (srbtf)shortest next burst time first (snbtf)shortest total burst time first (stbtf)does srbtf have the least average turnaround time? if yes prove it in explanation, if no give an example schedule which is not srbtf but has lower turnaround time. does snbtf have the least average turnaround time? if yes prove it in explanation, if no give an example schedule which is not snbtf but has lower turnaround time. does stbtf have the least average turnaround time? if yes prove it in explanation, if no give an example schedule which is not stbtf but has lower turnaround time.

When designing content as part of your content marketing strategy, what does the "think" stage represent in the "see, think, do, care" framework?

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?
