----------------------------------- gbudwal Sun Jan 25, 2004 4:50 pm SOME DEFINITIONS ----------------------------------- i needed some definitions if anyone could help all i need to know wat it is and what it does very very simple definitions nothing complex ABACUS Analog Digital Boolean algebra capacitor Capacitor farad transistor CMOS subprogram loop application program diode carry bit ASCII EBCIDIC Operating Systems algorithm Linux pseudo code top-down diagram top down programming UNIX method programming DMA EOF LEX truth table recursion peripheral ----------------------------------- Andy Sun Jan 25, 2004 4:58 pm ----------------------------------- wtf? y is this in the turing section and how does this have to do with computer science... ----------------------------------- gbudwal Sun Jan 25, 2004 5:00 pm ----------------------------------- didnt mean to get u mad or anything these definitions will be on my comp science exam tomororow grade 11 ----------------------------------- gbudwal Sun Jan 25, 2004 5:01 pm ----------------------------------- and the only language we learned in class from day 1 is turing ----------------------------------- Andy Sun Jan 25, 2004 5:02 pm ----------------------------------- well go to some computer dictionary site and search for these then... r u sure this isnt for computer engineering? ----------------------------------- gbudwal Sun Jan 25, 2004 5:30 pm ----------------------------------- im positive its compuer science lol ICS-3M0 i took engineering and dropped it cus it had to much of this shit... ----------------------------------- shorthair Sun Jan 25, 2004 5:39 pm ----------------------------------- First of all watch the language , second of all il answer every definition for you , in full detail for 5 $ paypal , and astly , if you kknew anything about those definitions you would know that 50% of them are nothign to do with programming ( rough guess ) at least take a look at htem , i mean some of them are easier than easy ----------------------------------- gbudwal Sun Jan 25, 2004 5:47 pm ----------------------------------- my msn email is hiphop_matrix@hotmail.com msg me and ill send u 5 bucks ----------------------------------- Andy Sun Jan 25, 2004 5:50 pm ----------------------------------- LOL... ever heard of google? ----------------------------------- shorthair Sun Jan 25, 2004 6:05 pm ----------------------------------- I would have done them if you hadnt gone around making multiple threads , and have you actually looked at hte list , i mean " loop " is on that list ,if your in grade 11 compsci and you dont know what a loop is then seriously , you should read some compsci tutorials ----------------------------------- gbudwal Sun Jan 25, 2004 6:12 pm ----------------------------------- yeah i made a mistake sorry cus i thought i was in the right area and i wasnt that was my fault so just lemme know if ur gonna do em or not if not ill try finding them i know what loops is but i cant really defin it my english is really bad ----------------------------------- Mazer Sun Jan 25, 2004 7:15 pm ----------------------------------- I'd have considered doing them but... how do I know you'll send me the $5? ----------------------------------- shorthair Sun Jan 25, 2004 7:29 pm ----------------------------------- he told me 1/2 before 1/2 after , i was gonna do it , but i just found out ( the real reason ) that i have another chapter of physics to study for , ( exam tommorow) ----------------------------------- gbudwal Mon Jan 26, 2004 1:57 am ----------------------------------- ill send the money before if u want ----------------------------------- aliveiswell Mon Jan 26, 2004 9:53 am ----------------------------------- ill do them, just give me your bits: ABACUS - the early calculator that had the little sticks with beads on them, invented (i think) by the babylonians Analog- the signal used by telephone lines, which a modem converts to digital (im pretty sure) Digital - the signal used by computers, which the modem converts to analog (im pretty sure) Boolean algebra - the aljebra used for showing the workings of a logic gate (ex. an or gate with two inputs = A + B = C), im pretty sure about that capacitor - an electrical component used to store an electrical charge Capacitor -uhhh, same thing i think farad - the measurement used to measure how much charge a capacitor can hold (i think) transistor - an electrical component that works as a switch, (like in an amplifier), i don't really know this one CMOS - that is where all the basic computer stuff is stored that helps boot the computer, holds the date/time, etc. subprogram -? loop - a structure thing in programming languages that allow things to be repeated for and infinite amount of time, or for a set amount of time, etc. application program - a program that does something (i think), like notepad, internet explorer, etc diode - an electrical component that makes sure a current only flows in one direction(it won't let the current "past" in the other direction), used mainly in AC (current that alternates), and not in DC which flows in one direction carry bit - ? ASCII - ? American Standard Characters (?), something like that. the code behind the characters on a keyboard (i don't really know), used by PCs EBCIDIC - same as above but used on IBMs cause they haven't fallen to their knees for the almighty microsoft (yet) ( ithink) Operating Systems - actually i can't find a definition in me for this one, though this is probably the easiest one here... a program that is the basic part of the computer that allows all programs to run, etc. algorithm - a written thing that comprises of regular english and programming language to show how you are going to do the problem (the code) Linux - an OS (operation system) that is open source, more powerful than windows, allows noob hackers to feel good, and gets you chicks cause it makes you look smart pseudo code -? top-down diagram - im guessing a diagram of a circuit board that shows the top and the bottom of it top down programming -? UNIX - ?, an OS that Linux was derived from, that is used mostly by large companies for large networks (i think) method programming -? DMA - isn't that the engine used by GTA 3 ? EOF - ? LEX -? truth table - a table used to show what the output would be for a logic gate for each combination of high/low inputs recursion -? peripheral- hardware that is not in your computer case (?), like a printer, external zipdrive the funny thing is, most of those were from my comp engineering class. sorry to anyone to said they were being paid, but people need to pass their exams. ----------------------------------- McKenzie Mon Jan 26, 2004 10:29 am ----------------------------------- subprogram - a function or procedure designed to carry out one specific task. carry bit - when you add two binary bits you get: 0 1 0 1 0 0 1 1 - - - - 0 1 1 10 the 1 bit in the 1 + 1 is called the carry bit. If you were adding a bunch of bits this carry bit would be carried into the addition to the left. ASCII - American Standard Code for Information Interchange pseudo code - sorta half-english/half-computer language used to plan programs. top down programming - starting with the whole program you break it down into subprograms, and there into furter subprogram until you can code each of these small versions method programming -? DMA - direct memory access, a technique for transferring data from main memory to a device without passing it through the CPU. EOF - End Of File - used to stop reading from a file LEX -A Lexical Analyzer Generator recursion - when subprogram calls itself. ----------------------------------- jonos Mon Jan 26, 2004 12:15 pm ----------------------------------- what is a lexical whatever (LEX)? ----------------------------------- McKenzie Mon Jan 26, 2004 12:59 pm ----------------------------------- One of the problems with computer TLAs (Three Letter Acronyms) is that they often get more than one definition. The LEX I was refering to is a tool you use to help when you are actually making a compiler of your own. I'm not sure if there is a non-unix version of it, and I'm not sure why it's being talked about in ICS3M
