Identify the correct translation into logical notation of the following assertion. Someboysin the classaretaller than all the girls Note: taller(x,y) is true if x is taller than y.

CompanyXshipped 5 computerchips, 1 of which was defective, and Company Y shipped 4 computerchips, 2 of which were defective. One computerchip is to be chosen uniformly at random from the 9 chips shipped by the companies.If the chosen chip is found to be defective, what is the probability that the chip came from Company Y ?

Consider a computer system that stores floating-point numbers with 16-bit mantissa and an 8-bit exponent, each in two’s complement. The smaliest and largest positive values which can be stored are

in comparison with static RAM memory, the dynamic RAM memory has

The Hexadecimal equivalent of 011111001101111 00011 is

Disk requests are received by a disk drive for cylinders5, 25, 18, 3, 39, 8 and 35 in that order. A seek takes 5 msecper cylinder moved. How muchseek time is needed to serve these requests for a Shortest Seek First (SSF) algorithm? Assumethatthe arm is at cylinder ?,0 when the last of these requests is made with none of the requests yet served

Consider a system having ‘m’ resources of the same type. The resources are shared by 3 processes A,B,C, which have peak time demands of 3,4,6 respectively. The minimum value of ‘m’ that ensures that deadlock will never occuris
