A packed chromatographic column is a piece of tubing through
which a carrier fluid flows; it is packed with a porous medium
that has a significant tendency to sorb chemicals of interest. A
pulse of 2,4-dinitrotoluene is injected into one end of the
column, and then moves at a velocity according to its distribution
coefficient between the moving fluid and the porous medium.
How many characters per second can be transmitted over a 1200-baud line in each of the following modes? (Assume a character code of eight bits.)
a. Synchronous serial transmission.
b. Asynchronous serial transmission with two stop bits.
c. Asynchronous serial transmission with one stop bit
A DMA controller transfers 32 bit words to memory using cycle stealing. The words are assembled from a device that transmits characters at a rate of 2400 characters per second. Each character is 8 bit length. The CPU is fetching and executing instructions at an average rate of 1 million instructions per second. By how much will the CPU be slowed down because of the DMA transfer?

Differentiate between RISC vs CISC architecture?
What is Direct Memory Access? Explain the working of DMA. What are the different kinds of DMA transfers?
Explain how control measure are used to prevent accident
write a function that takes in an array of words and returns the smallest array of characters needed to form all of the words.the characters don't need to be in particular order.
Design and Simulate a dipole Antenna at 1500MHz and compare it with Monopole results.
It has been known that a fixed dose of a certain drug results to an
average increase of pulse rate by at least 12 beats per minute with
a standard deviation of 5. A group of 20 patients given the same
dose showed the following increases: 15, 12, 10, 8, 14, 15, 16, 11,
7, 13, 9, 10, 12, 11, 9, 10, 17, 14, 15, 7. Is there proof to show that
this group has a lower average increase of pulse rate than the ones
in general? Use 0.05 level of significance
