Computer Definition and 998 Threads

I need some topics to write about for my research paper. I'm writing about how computer science and technology both force the other to expand. The 3 examples I'm writing about now are hardware/processor enabled security (ie I'm comparing 16bit x86 which had no security to 32bit which did)...

Hello there, I'm not really big on posting around here, mostly just lurk and read. Today however I feel I really need some help with making an important decision in my life. Being that this is the physics forums, and almost all of you are going to have a better knowledge of physics and even...

when i pressed the power button on my imac g3 desktop computer, there was a bright flash from inside the computer (it has a transparent blue top), and a burning smell such as when a fuse blows i tried using a different power lead a few hours later, the same thing happened again everything...

i haven't clicked on it. better safe than sorry.:smile: if it is somebody ought to remove it. Have A Nice Day!

What is auxiliary state?

Hi there. I'm currently in grade 11. I'm taking courses like physics, chemistry, math and computer science. I do very well in school when I put in the effort but lately I've just been procrastinating and being sort of apathetic about everything except technology. I am very addicted to the...

One of my life goals is to really just learn how a computer works. I want to learn all the mathematics it takes to understand how a computer works, i want to know the history of it, i want to basically go back to first principles of how a computer works and understand how it evolved into it's...

Why quantum computers are faster?

Hi, I'm new to Physics Forums and in dire need of your help. Please bear with me, here it goes: Though I'm sure this goes through every person's head who wants to go through University, I really have no good idea of which courses I want to take. I thought maybe computer science would be the...

The big stumbling block has been electrical interference on memory chips, and a claimed solution has been found, paving the way for flexible computers, and display technology. Not too far in the future this may be possible: watch the youtube video: Rhody...

Hi. I'm wondering if you leave your computer or any electronic devices near you operating when you are doing your homework or are studying. If so, do you find that it distracts you?

What are some example careers? What do you usually do? Hardware? Make computers?

Would you consider a computer scientist (someone with a PhD & doing research) as a traditional scientist? I mean, there's no rigorous method that defines computer science as a "science" in the proper sense that is guided by the scientific method of making hypotheses, gathering evidence...

I got my old tests back today. And I don't understand what i did wrong?? p.s. teacher is not available at the moment( sub//part time teacher). 1. How much memory does it take to hold a 512x512 color image with 256 different levels of color(states)?? Okay, this one I just guessed and...

I have a Dell Inspiron 1525 and it won't charge. When I plug it in the charger, all it says is "Plugged in, not charging." I have replaced the battery but it still won't work, what is going on? Also, there is not enough power in the computer to keep going, so the charger has to be plugged in...

Hi, Would anybody tell me that how can I recognize the viruses so that I may give up clearly? Regards,

i'm looking for computer simulations of expanding space. i made a couple of very very very simple models and my results were no where near our current model of space. hence, I'm looking for work that has already been done on the subject.

Hello!So recently I've been playing with 555 timers. And I am beginning to understand how powerful they can be.With that reset pin switching capabilities are endless. But that led me to thinking.How can I make that switch, which you have at your computer, that power on and off switch. The switch...

I am wondering how I would create a really simple electronic calculator/computer

On my newer computer, the Latex displays pretty decently. (Not as good as on the ipad though.) On my older computer, the Latex displays pretty crappily, rough around the edges and so forth. What determines the clarity of the Latex display? Is it the graphics card in the computer? or are there...

Hai, I see many programming languages with instructions etc., and computer performing accordingly. Also, I hear computer converts the instructions into binary and it performs operations. Well, what I don't get is, even though it converts the instructions binary, how can it understand that...

Given an arbitrary one dimensional vector v imputed by the user for example v='Helllllloooooo' or v='Helo' I was able to append empty characters onto anyone dimensional vector that the user can enter so that way the total length of the vector is a multiple of 8 characters of long or not add...

Hello, everyone. My name is Sam. I am a freshman in college, and I am-- let us just say-- very worried about how in the world I could ever get a job in the field I want. I have grown up in Louisiana, Shreveport. My entire life I've been prepped to the belief that you go to college and then...

I'm currently in high school and I'm deciding whether or not to take a computer course such as Computer Science. The thing is, it seems like a dull subject (sorry to those who like it, this is just my opinion) involving basic mathematics. My friends have told me it's helpful for university...

I am trying to understand how light works in computer graphics. Especially OpenGL 3+. So I was given a paper that says how to calculate light. It says "normalise the vectors before taking the dot product".How do I normalize vectors and why? I have to compute the normals to a vertex. What is a...

Can someone explain to me how fluids are simulated using particles? What equations to solve? How to update the particle positions? How awfully computer intensive is the algorithm? Can a simulation using a 100 * 100 * 10 grid run okay on the average computer? The more I read the more I realize...

I was just wondering if anyone knew of software that would allow me to simulate magnetic induction. I'm researching into the effects distance and the number of windings has on the effect of transfer efficiency between two coils. I've seen lots of people mention Maxwell, but they seem to...

As Black Friday is fast approaching, I thought it might be helpful to share your potential computer related purchases here, so that others may benefit from store and online purchases. There are people I work with who get up at the crack of dawn to get a good position in line at your...

I had a test in my computer science course in which I was asked if any while loop can be replaced with a for loop. I put true. I guess the answer was false. My professor said that if you had a while loop in which you asked the user to input a certain value that had to be within a certain...

Hello, I am in my first year in college and my major is COMPUTER ENGINEERING. However I just learned that computer engineering is supposed to be about hardware stuff, and I love programming and coding, so that means the software stuff. My dream job would be to work at Apple, Microsoft or Google...

First of all, I haven't the slightest idea how a quantum computer actually works but I understand that it is theoretically possible to make them and they could, in theory, be used to compute things that a classical computer would take too long to compute. (i.e. large combinatorial problems like...

I have a question about a security practice that is in place at my work. I think the practice isn’t based on credible science, and no one has been able give me a solid justification. My background is almost entirely in math so I was hoping to get an engineer’s take on this: Security is a...

Hello, everybody. I have been actually afraid of posting this thread, because I usually lack in time (you know I have to work to survive), and as far as I know philosophical threads tend to be really long and complex. I consider myself as a layman when it comes to philosophy, so I hope I won't...

From elementary to high school I've had teachers who've droned on and on trying to explain minute details about the concepts they're teaching. I've almost always found it more difficult to follow the teacher's train of thought than to just learn the concept myself, so I always just read the...

I am trying to play a movie from my macbook pro with the video to a standard HD tv and the audio to a guitar amplifier. I connected the guitar amplifier to my macbook pro through a 1/4" to headphone jack cable and the sound outputted to the amp was fine, just as I wanted it. As soon as I...
