What are uses of computer in space exploration?

Space exploration requires complex calculations using many variables. These apply to astronomical information for planets, moons, and other bodies, as well as the precise accelerations and trajectories for spacecraft and probes. On Earth, travel on the surface or in the air can be controlled effectively by human coordination and relatively simple vehicles. In space, small errors or miscalculations can create serious problems that cannot be easily corrected. Computers provide faster and more flexible handling of data, both in planning a mission and in analyzing parameters during a mission. Without them, effective space exploration would be nearly impossible.

How did the term computer nerds originate?

The word Computer is self explanatory. The word nerds started out as knurd which is drunk spelled backwards that meant a person studied rather than partying. It was then altered to nerd meaning somebody dull. So computer nerd is someone that spends all their time on the computer rather than socialising.

How do you download music using 7zip?

To download music using 7Zip you need to open and access the file, select the music you wish to download and begin download when prompted.

Why you use binary number system in digital?

It has to do with the way computers are built at their core. At the base level it all comes down to on or off. Binary is perfect for that. 0 = off, 1 = on.

How is the USB port called that stays on You can still charge something through it even if the computer is turned off?

How long until Chess can be solved under Game Theory given the current rate of exponential increase in processor power?

Chess is too complicated ever to be "solved." There is no single method by which every game can be won. The world's strongest computers routinely beat each other in computer chess tournaments, and the games do not display any single method that could lead to a solution according to Game Theory.

What A CPU really only understands instructions that are written in machine language.?

A CPU will have an "instruction set" which consists of primitive instructions i.e a command like MOVE:1002,1003 could be an example of an instruction to move the contents in memory location 1002 to the memory location of 1003. Some CPU's operate as a RISC (Reduced Instruction Set Computer) and others operate as a CISC(Complex Instruction Set Computer). Which basically means some have more "primitive instructions" than others but the more complex an instruction is - The more work will be needed to execute it. Alan Turing proved only 6 of these primitive commands are needed to compute anything that is "computable" by machines. Nowadays, programmers will write code in an "high level" language which contains more of these "primitive commands" but then the code will be compiled into a set of instructions that the CPU can actually execute (i.e to the instruction set of the targeted CPU). If we were to try to write any sufficiently complex program using only the instruction sets of CPU's, it would become very complicated for humans to understand and would take a ridiculously long time.

Who is Captain Crunch in relations to computers?

Captain Crunch is the nickname of John Draper, a rather infamous phone phreaker. Before there were computers and computer hackers, there were phone phreakers who hacked the phone system in various ways.
