Consider a system running 10 i/o-bound processes and 1 cpu-bound process. assume that the i/o- bound processes issue an i/o operation once for every millisecond of cpu computing and that each i/o operation takes 10 milliseconds to complete (we assume that there is no competition among i/o operations). assume that the cpu-bound processes do not issue any i/o operations. a round-robin scheduler with quantum size 1 milliseconds is used to schedule all these 11 processes together. we assume that the context-switching overhead is 0.1 millisecond and that all processes are long-running tasks. calculate the cpu utilization.

Which syntax error in programming is unlikely to be highlighted by a compiler or an interpreter? a variable name misspelling a missing space a comma in place of a period a missing closing quotation mark

Scientists have changed the model of the atom as they have gathered new evidence. one of the atomic models is shown below. what experimental evidence led to the development of this atomic model from the one before it? a few of the positive particles aimed at a gold foil seemed to bounce back. the colors of light emitted from heated atoms had very specific energies. experiments with water vapor showed that elements combine in specific proportions. cathode rays were bent in the same way whenever a magnet was brought near them.

Formatting rows and columns is similar to cell formatting. in an openoffice calc spreadsheet, you can format data entered into rows and columns with the of the rows and columns options. you can insert rows and columns into, or delete rows and columns from, a spreadsheet. use the insert or delete rows and columns option on the insert tab. alternatively, select the row or column where you want new rows or columns to appear, right-click, and select insert only row or only column options. you can hide or show rows and columns in a spreadsheet. use the hide or show option on the format tab. for example, to hide a row, first select the row, then choose the insert tab, then select the row option, and then select hide. alternatively, you can select the row or columns, right-click, and select the hide or show option. you can adjust the height of rows and width of columns. select row and then select the height option on the format tab. similarly, select column, then select the width option on the format tab. alternatively, you can hold the mouse on the row and column divider, and drag the double arrow to the position. you can also use the autofit option on the table tab to resize rows and columns.
