After an employee reported slow network speeds and application responsiveness, the desk asked the company's security administrator to review the following firewall logs from the employee's computer
2017-05-30 12: 12: 31 allow tcp 192.168.1.236 192.168.1.1 30295 21
2017-05-30 12: 12: 32 allow tcp 192.168.1.236 192.168.1.1 30296 22
2017-05-30 12: 12: 33 allow tcp 192.168.1.236 192.168.1.1
2017-05-30 12: 12: 33 allow tcp 192.168.1-236 192.168.1.1 30297 80
2017-05-30 12: 12 : 33 drop tcp 84.176-55.103 192·168·1.236 104 34 445
which of the following can the security administrator infer and report to the desk based on the above logs?
a. the employee's computer is infected with a worm.
b. the employee's computer firewall should be enabled
c. the company's router is actively listening to unneeded services
d. the employee's computer is being actively scanned.

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?

Jason, samantha, ravi, sheila, and ankit are preparing for an upcoming marathon. each day of the week, they run a certain number of miles and write them into a notebook. at the end of the week, they would like to know the number of miles run each day, the total miles for the week, and average miles run each day. write a program to them analyze their data. your program must contain parallel arrays: an array to store the names of the runners and a two-dimensional array of five rows and seven columns to store the number of miles run by each runner each day. furthermore, your program must contain at least the following functions: a function to read and store the runners’ names and the numbers of miles run each day; a function to find the total miles run by each runner and the average number of miles run each day; and a function to output the results. (you may assume that the input data is stored in a file and each line of data is in the following form: runnername milesday1 milesday2 milesday3 milesday4 milesday5 milesday6 milesday7.)

Me and category do i put them in because this is science
