COMPUTER SCIENCE Assume 151 and 214 are signed 8-bit decimal integers stored in two’s complement format. Calculate 151 + 214 using saturating arithmetic. The result should be written in decimal. Show your work Verified answer COMPUTER SCIENCE Multithreading is a commonly used programming technique. Describe three different ways to implement threads, and compare these three methods with the Linux clone() mechanism. When might using each alternative mechanism be better or worse than using clones? Verified answer
COMPUTER SCIENCE Design an odd-parity circuit. This is a circuit that has three inputs and one output. The circuit outputs a 1 if and only if an even number (0 or 2) of its inputs are a 1. Otherwise, the circuit outputs a 0. Thus the sum of the number of 1 bits in the input and the output is always an odd number. (This circuit is used in error checking. By adding up the number of 1 bits, we can determine whether any single input bit was accidentally changed. If it was, the total number of 1s is an even number when we know it should be an odd value.)

Which operating system is usually distributed free?The advantages of Linux are that it is free, and there are many different distributions—or versions—you can choose from. According to StatCounter Global Stats, Linux users account for less than 2% of global operating systems. However, most servers run Linux because it's relatively easy to customize.
Is an open source operating system whose source code is freely available to everyone?Linux is a free, open source operating system (OS), released under the GNU General Public License (GPL). It's also become the largest open source software project in the world.
What kind of software can be distributed by anyone to others at no cost?Open source software is copyrighted software that is distributed at no cost for a trial period. Developers of freeware rely on the honor system, trusting users to send payment if software use extends beyond the stated trial period.
