Assume that the scheduler runs threads in FIFO order with non-preemptive scheduling (no preemptive time-slicing), and threads are placed on wait queues in FIFO order. Trace the execution of this program until it returns from selfTest and (a) write the sequence of context switches that occurred up this point, (b) write the output of the program, and (c) list the queues that the threads are on, and their relative order if more than one thread is on a queue.

3. (6 pts) internally in the computer, with few exceptions, all numerical computation is done using binary numbers. output, however, often uses ascii, which is formed by appending 011 to the left of a bcd code. thus, an algorithm that directly converts a binary integer to a bcd integer is very useful. here is one such algorithm 1) draw lines to the left of the binary number to bound the expected bcd decades. (each decade is a group of 4 bits.) move the binary number one bit to the left. add 0011 to each bcd decade containing a binary value> 0100 repeat steps 2-3 until the last bit in the binary number has been moved into the least significant decade position. (note that when the last bit has been shifted into bcd decade, step 3 is not repeated.) read the bcd result. 2) 3) 4) 5) a) execute the algorithm for the binary number 1101101 b) execute the algorithm for the binary number 01110101110 4. (4 pts) represent the decimal number 3568 in bcd; excess-3 code; ascil; and hex.

Check my work the microprocessor is a(n) circuit, which is designed to process data based on a set of instructions. most desktop and laptop devices contain a microprocessor based on the standard. most tablets and smartphones contain processors based on technology. a microprocessor's circuitry is designed to perform a limited number of tasks contained in its set. during processing, an instruction is loaded into the processor's unit. data is loaded into registers in the processor's where arithmetic and logic operations are performed. microprocessor performance can be measured by its speed. other factors affecting overall processing performance include word size, cache size, and instruction set complexity. most digital devices contain only one microprocessor chip, but today's multi- processors contain circuitry that supports parallel processing. computers contain various kinds of memory. random memory is a special holding area for data, program instructions, and the system. it stores data on a temporary basis until the processor makes a data request. ram is different from disk storage because it is , which means that it can hold data only when the computer power is turned on. computers also contain read- memory, which is a type of non-volatile memory that provides a set of "hard-wired" instructions, called the loader, that a computer uses to boot up.
