The real magic of the CPU is how it knows which circuits to useĪnd when to use them. Send and receive information to and from different Simple math and logic, it has other circuits to Things, so inside it has smaller, simpler parts The CPU is the master chip that controls all the other parts of the computer. But how do the hardware and the software interact with one another? Lets start at looking at a computer's central processing unit, or CPU. Software that me and my teams use at Amazon to understand Software can be anythingįrom apps and games to webpages and data science Software is all of the computer programs, or code, running on this machine. (laughing) - When you look inside a computing device you see a bunch of circuits,Ĭhips, wires, speakers, plugs, and all sorts of other stuff. Basically bringing the hardwareĪnd the software together to give you all the games My name is Jerome Holman and I'm a program manager on Team Xbox, And I have a really fun job. Software gets out the door and her job is to nap under Particular is that I get to bring my dog with me to work every day. (lively music) (women laughing) - Hi, my name's Erica Gomez and I'm an engineering manager at. Programs often include a mix of stuff which implements algorithms, and stuff that doesn't.Ī game might use a collision detection algorithm to see when a hero is hit by lazers,īut a lot of the code which defines what types of objects are in the game normally wouldn't be considered as algorithms Most people wouldn't consider a "hello world" program to be an algorithm.Ī program which does nothing, which is a perfectly valid program, also would not be considered to be an algorithm. (it was an algorithm intended for humans, not computers)Į.g. when you learned long division in school, you learned an algorithm on how to do long division A file of executable instruction is known as an executable.Īn operating system (which is a program itself) runs on the computer and tells the computer when to run other processes, including executables.Į.g.
It can be reduced into a bunch of 1s and 0s that can be interpreted by a computer as executable instructions. An algorithm is a step by step procedure on how to do something.Īn algorithm could be executed by a person, a computer, or a machine.Ī program may implement an algorithm in a programming language.
