(a) Convert 10111102 into the hexadecimal number, answer without base (e.g. 1A).

(b) Convert 1110011002 into the decimal number.

(c) Following is an example of a valid IPv6 address that uses hexadecimal numbers: 0210 : AF69 : F090 : 6A05 : 0000 : 0020 : 3257 : 9652. Convert AF69 into a format that the computer can interpret, answer without base (e.g. 1010).

Chakciboo and Shalolo want to check whether the mainframe in the server room has been attacked by a Polymorphic Virus. Shalolo chatted with her friend using the Japanese language through WhatsApp about this attack. What's the coding scheme used?

Determine the boolean expression for a given logic statement or scenario. The output X, of a logic circuit that drives the display of the alert, must have a value of 1 when either one of the conditions is met: Carbon dioxide pressure too low and temperature > 3000C Water pressure > 10 bar and temperature > 3000C The inputs to the system are: Input Binary Condition P 0 Carbon dioxide pressure acceptable 1 Carbon dioxide pressure too low T 0 Temperature <=3000C 1 Temperature >3000C W 0 Water pressure <=10 bar 1 Water pressure >10 bar. Write without space (e.g. X=P.T.W).
