I think coders put in codes. Sry if that does not help.
Answer:
twos complement value is (-2^15 -1) -32768 to 32767.
excess notation value is -32768 to 32767.
unsigned binary value is (2^16) 0 to 65535
Explanation:
Excess notation: used to represent signed integers. Always uses fixed number of bits with leftmost representing the sign.
Twos complement notation: As opposed to excess notation, a sign bit of 0 is used to represent the non-negative (+) sign and a 1 for the negative (-); again, zero is included in the non-negative set.
Unsigned Binary values: are binary values/bits that don't have signs
Answer:
Passive security attack are the unauthorized disclosure in the network attack. In this type of security attack a system are use for monitoring and sometimes scanning the open port. It basically include the monitoring the unprotected data and traffic analysis.
On the other hand, active security system modify the transmitted data and gain the unauthorized access from the computer system.
This type of security attack basically monitor the file transfer and electronic mail from the attacks which can be pass in the form of viruses in the computer system.
