Computer Science

Hi, I have a question regarding Ones and Zeros, I assume everybody on this forum knows about binary code. But I'm interested where the binary streams are converted into real text. Let's say, I send a binary stream from my own made usb device to my computer. This binary stream contains: "001000001", this is the ASCII letter "A" (yes capital). So I'd like to know how and perhaps where the system converts "001000001" to "A". And if it might be possible to assign "001000001" to a different ASCII letter. Kindly regards, Padam

difference between internet and extranet with example?

What does the prefix 0x (as in 0x565) mean in the hexadecimal numeral system? What is this prefix for?

Is the following always secure? (Let's assume correct file extension) 1. Installing fonts 2. Running portables (no-installation programs that you can run from your thumb drive)? 3. Preview windows of sites? For example, you hover the muse over a link and it shows you a preview of the site it leads to. Wouldn't accessing a preview of a malware website also launch all its scripts?

where fixed length and variable length record uses?give an example using file name...

Hello all, I'm very new to computer programming and I'm really needing help on where to start. I've worked in the IT field for several years and I'm wanting to narrow my skills down to programming, if that makes sense. I didn't receive an education in computer science and I'm basically self-taught. Should I be taking classes to learn the basics of programming and go from there? I basically just need a push in the right direction. Any advice or suggestions would be greatly appreciated. Thanks.

I'm starting to learn C++ but I would like to find some problems to practice my skills on. I don't know that much except for the very basic like looping and if-statements (Didn't learn to make a class yet because I'm preoccupied with studying for midterms as of now). So does anyone have something I can work on or a website with things of this sort? Thanks.

I am trying to generate a random number between i and j. The code at the bottom always generates the same number which is 42. How can I fix this ? int RandInt (int i , int j) { return rand( ) % (j-i+1) + i ; }

What's your experience in working on the same .xcf files between different systems? On a Windows computer, I have trouble playing .mov files saved by Adobe Flash on a Mac system, even though Windows has the same version of Adobe Flash (CS5). Even worse, Adobe's .fla work files saved on a Mac don't quite want to play nice on Windows. I hire different people to work on the same animation files, but they have different computer systems so it's becoming a real pain with incompatibility. How does GIMP fare in this manner?

Hi guys, Traditional voting via paper ballots at polling stations, meant that each individual was free to vote for his candidate in complete privacy. A father could vote for a separate candidate and a son for another candidate. So I was wondering is there any way in which to ensure similar privacy when using Internet voting as well ? Or will that then depend on the voter to ensure that he is in a 'private' environment? I understand its probably not big of an issue since at worst one would vote in front of friends and family...but doesnt it regardless prove a security flaw in internet voting? Thanks Regards evy5maa

1) Are there any program languages that don't let you insert comments? By this I mean the extra notes and whatever that have no additional effect or function other than to be reading material for anyone viewing the underlying source code. 2) Do all files types let you place comments in them? For example, putting comments into a .jpeg, .txt, .exe, .ogg, .whatever, and they're only viewable if you check the header info or wherever they'd normally go (and the comment doesn't interfere with the normal viewing or executing of the file). 3) Is there a size limit to the comment you're able to put in #1 or #2? 4) Can you do a plain text comment for all instances of…

I am new to ANSI C and want to use it to write some programs for personal use - and release them into the open source domain. Where can I find descriptions and syntax for the macros and functions in the thirteen standard header files? I am an old guy (61) and have used some C before but it has been so long that I have forgotten just about everything I once learned. I have gleaned a lot from the internet but I am getting tired of looking up each function to learn how to use it. A second question: Is there any way to get a one keystroke input from the keyboard in ANSI C like I could get with getch() in the "old days"? Thanks for your time, Paul

Hello Friends, I wana ask that if two processors Processor01 and Processor02 have same number of components but Processor01 had 16 registers on the other hand Processor02 has 64 registers. Which processor is best in terms of its speed, size and cost? Take Care

Why does a CPU's, PSU fan specially most of the desktops, makes a loud humming noise at the start up and then it becomes normal after some minutes?

Hi guys, So, I graduated with a physics degree and research honors. In my research I was heavily involved with modelling, particularly with mathematica and matlab. I am also a relatively proficient php/mysql programmer and I have a good grasp in jQuery, AJAX and developing CMS extensions. I have a few small projects under my belt, most are small jquery and relatively small CMS extensions. I program for fun, and I have been doing that since around 6th grade. I'm starting out in Perl now, and its a pretty smooth ride so far. I also took a C++ course in college (waste of time though.. very veeeery basic) Problem? I have no official programming education. I want t…

As a keen gamer I particularly enjoy games which concentrate a lot on environmental conditions of the surroundings, i.e., snow in winter, details of snowflakes or ice on the roofs etc, and of course scientific accuracy ... but after a while it all ends up inspiring me to "want more". PC games need to escalate to a new level of realism. A nice attempt has been made by Crytek (http://en.wikipedia.org/wiki/Crysis) but even that is not enough. The majority of gaming is still on our computer screens and TV's. Virtual Reality is the future by all means. Even though it is still in its infancy I can't wait for it to advance for I'll be the first customer on any major VR Gaming ev…

Regarding passwords. How can a hacker find a usable password to another's Internet account in a relatively short time? It takes several seconds for the accepting server to accept/deny a provided password. It would seem to take weeks to shotgun a brute-force number of passwords to finally come across the right one, even with software doing the work, right? This doesn't seem feasible. Where am I wrong?

How to be a Good Programmer in C++ programming language ???

hi everyone, I have trained MLP neural network and identified my system with this network. for training, I have normalized all input data so the range of data that enters the network is changing from zero to one. for normalization, I have used this formula: {(Input(i)-min(input space))/(max(input space)-min(input space))}. now i want to use this network to control my system. the data that network generates is somehow normal and my system cannot accept these data. What should I do with this data? I have tried the reverse transformation but since system is working online the max and min of it is not known. anybody have any idea?
