In a batch operating system, three jobs jobi, job2, job3 are submitted for ex- ecution. each job involves an i/o activity, a cpu time, and another 1/0 activity. job1 requires a total of 21 ms, with 3 ms cpc time. job2 requires 29 ms total time with 5 ms cpu time. job3 requires 14 ms total time with 4 is cpu time. 3.1 what will be the cpu utilisation for uniprogramming? write down all interme diate steps. 3.2 what will be the cpu utilisation for multiprogramming? write down all inter- mediate steps

Are segments of dna that determine traits and are passed down from parents to offspring.

What is the largest decimal number that can be represented by a binary number with 4 place values? (remember, each place in a binary number has a value of a power of 2, starting in the ones place with 20.)

You will be given two character arrays of the same size, one will contain a number of ships. ships will move around the character array based on which way they are facing and the route they are on. routes are given in the other array. the route consists of '-' and '|' for straight paths, '\' and '/' for curves, and '+' for intersections. there are ships on these routes. ships always face a direction, '^' for up, '> ' for right, 'v' for down, and '< ' for left. any time the ships hit a '\' or a '/' it will turn as you would expect a ship to turn (e. g. a '^' that moves into a '/' will turn right). at an intersection, ships will always continue straight through. all ships move at the same speed, ships take turns moving and all ships move during one 'tick'. the one in the most top left goes first, followed by those to its right, then the ones in the next row. it iterates along the rows and then down the columns. each ship moves one space on its turn moving along the route. your function needs to return the position of the first collision between two ships and the number of ticks before the crash occurred.
