Anti-wikipedia arguments are moronic; unless you see a page at the wrong time (ie less than thirty seconds after someone replaced every "the" with "PENIS") you're getting information as accurate as anywhere else on the web. wow, after I wrote that, I reread your sentence. I thought yous aid "I don't think wikipedia is a reliable source" but you said "they don't...". Nevermind then, but anti-wikipedia arguments are lame and therefore it's no wonder why schools block it ("YOU SEE MR. FIFTY YEAR OLD TECH GUY, ANYONE CAN EDIT IT." "okay it's blocked"). |

My school blocks it too, because they don't think Wikipedia is a reliable source that should be read by anyone. I wish I was kidding too  |

Just copying the answers posted here is a bad idea. It'd probably be considered plagarism, hence, if the teacher Googles them you're boned.  |

Quick note: A byte is 2 digits in hex. 00-FF.
Open Architecture: Computers the end-user can upgrade without having to deal with restrictions based on proprietary components. That could probably be worded better. I think the best way to look at it is that PCs are open architecture, Macs are (close to being, if they aren't) closed architecture, video game systems (barring certain special parts) are definitely closed architecture. Hopefully you can get some kind of meaningful definition from that. |

Now that I think about it, it would be nice to have a General Homework help thread.
And have you tried searching Google or Wikipedia? |
| Sparx Posts: 490/529 |
Ok, now I just need the open architecture thing. Thanks for the help with the other ones, I couldn't find them I've edited the questions with my new answers.
Ok, I've finished. Now I just need to know if these answers are OK. |
| Skreename Posts: 1074/1427 |
Ahh. Okay. I know a bunch of forums disallow such talk.
Originally posted by Sparx Very much so. It was a MASSIVE boost when it got cracked by the allies. And the other improvement from a larger bitwidth (or the same thing, just in different terms) is that it allows for higher processing speeds with the same cycle time. You can get twice as much through a 64-bit pipe as you can through a 32-bit one. I'm not quite sure how to put that very well, actually. I remember it from my computer organization class two years ago, but barely. ...That description of analog vs. digital makes little to no sense. I'd suggest something about quality of the signal and how much it degrades over distance. Possibly how the analog carries the raw signal while digital has it converted to data which is decoded on the receiving end? EDIT: Simplest for bits and bytes: A bit is a single hardware state, either 1 or 0. A byte is 8 bits, commonly represented in hexadecimal. However, it can be represented in any numbering system. |

3. What are Bits and Bytes?
Data represented in the forum of numbers, there are 8 bits to a byte. Bytes can be represented in either hexadecimal or binary format. That's the only one I can be sure of. |

School computers block Wikipedia. I don't know why, as there's nothing wrong with it  And why did the homework thread die out? Well, seeing the number of homework threads/ posts/ questions.... Anyways, I found the ENIGMA information. Thanks Skreename  |
| Yoshi Dude Posts: 1114/1408 |
It seems like you could find these answers on wiki. I just did a quick check on 3-5 at least.Originally posted by SkreenameYep. There used to be a general homework thread even, but that died out. People don't ask for homework help that often. |
| Sparx Posts: 488/529 |
I was wondering or not if it was... but I wasn't sure, so I just did And WWII cryptography? That far back? |
| Skreename Posts: 1073/1427 |
Is this kind of topic allowed here?
Either way, for the ENIGMA one... Look up some stuff for cryptography during WWII. |
| Sparx Posts: 487/529 |
Ok, not really. But I do need some help. I've searched and haven't found anything. Can somebody check these answers for me, and maybe help with the unanswered ones? It's for my computer class, and I need to finish it and send it via e-mail by 12:00 AM tomorrow. I need someone to check my answers and help me with the rest. Can somebody help?
Edit: Crap. Let me get the actual work page thing. Edit 2: Ok. Here: Questions KarbosGuide Chapter 1 1. What is a mainframe? Mainframes and super computers are the biggest computers – million dollar machines, as big as a refrigerator or bigger. 2. What is a Workstation? Workstations are very powerful user machines. They have the capacity to execute technical/scientific programs and calculations, and typically use a UNIX variant or Windows NT as their operating system. 3. What are Bits and Bytes? Bits and Bytes are data represented the form of numbers. Bits are a single hardware state,1 or 0.There are 8-bits to a byte, are most commonly represented in hexadecimal (0-F), but can be also be represented using any other numbering system. 4. What does the author mean by standardized and open architecture? Open architecture is a type of computer architecture that allows users to upgrade their hardware in all of the computer hardware & components.This is the opposite of a closed architecture, where the hardware manufacturer chooses the components, and they are not generally upgradable. 5. What is a Clone? A clone is a copycat computer that can do anything the original can do, and some hard drive parts are identical, but these computers are sold with a different or no name. 6. Why is larger Bit width better? Because it allows a computer to process larger numbers in a single operation. 7. Who are Pascal, Boole, Babbage, and Atanasoff and what did they do? Pascal created a calculating machine at the age of 18, and his theories have affected a lot of scientific research. Boole founded a mathematics school and began to develop symbolic logic. Babbage began developing a number of claculating machines and created a steam-powered analytical machine. Atanasoff created the first digital computer called the Atanasoff-Berry Computer with his partner Clifford Berry. (Oh wow, no idea where the name came from =P ) 8. What is the difference between analog and digital? Analog on a phone or TV or anything that requires a signal, transfers the raw signal and degrades over distance, meaning lower phone sound quality, or in a TV, a lower picture quality, and usually needing usage of an antenna. While digital, on the other hand, converts that signal into data, and then decodes it once it reaches the receiving end. 9. What was the “ENIGMA”? The ENIGMA was a portable cipher machine used to encrypt and decrypt secret messages. It was a rotor-based machine that was used in World War II and Nazi Germany. |
