Hi, I am a grade 12 student, applying for uni for the coming September. And yet, I'm still having trouble with deciding my course. Electrical and Computer Engineering, I am confused with the two. From wiki and other places I see that Electrical is more concerned with telecommunications...

Write an assembly language program that uses ten memory locations (variables) filled with 0, starting at Address 30, and that stores the values 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, and 22 in them. Your program will store 2 at Address 30, 4 at address 31, 6 at address 32, etc. Your program must...

Hi, after reading this article, I was left wondering how the heck a quantum computer can be simulated. To begin with, how is a quantum computer of 42 qubits built up? And the how could this computer possibly be simulated? I mean, the wave function of one qubit is a three dimensional scalar...

Hello, I want to draw the detailed logic level diagram for a basic computer. For this i found a software that will work which is microsoft visio 2010. But i m not satisfied with that because it has some limitations. Such as re-arranging the wires automatically and also the simulation...

So I got accepted into engineering, which is just general engineering first year. However the university has asked me for my preferred discipline now, and I was about to put computer engineering. The thing is, i heard that taking electrical engineering as an undergrad degree is a better option...

User tries to login while standing and fails. Then sits down, tries again and succeeds. The behavior is consistent. The login always fails when the user is standing and continues to fail until the user sits down. What's wrong with the computer?

I am a Computer Science major and as of now, I am starting to feel like this is not want I want to do with my life. I want to be involved in the management aspect of technology. I don't know which degree will take me there. I am currently taking Data Structures and I hate that class. I feel like...

http://www.nytimes.com/2011/03/01/science/01compute.html?_r=1&pagewanted=print So - a question. Once this infrastructure is in place, do we have to revise all the algorithms we use? Just as we have to revise all of our algorithms when we're programming for parallel processors?

Hello I have bachelors degree in computer engineering from Pune University, India. I want to pursue further career in physics. I have scored 940/990 in subject GRE physics and I am now preparing for general GRE. Please suggest from which university (of US preferably) I can get masters...

(wasn't sure where to post this) Hey guys :) Are there any physics/mechanics computer games (i.e. for the PC). A friend of mine has shown me a game where you build bridges with trusses and ropes and a train passes through it. If the bridge isn't well-constructed, it'll break! That game is...

I am nearly done with all my basic undergraduate course work and will soon be pursuing the rest of my applied math degree. There are a variety of upper division classes that I have the option of taking. I was wondering which ones seem best suited if you were going to get your masters in either...

Hello everyone. I'm a third year Physics and Computer science student (predicted a 1st class - studying in the UK) and I'd like some advice on what to do in the future. I apologise in advance if this OP turns into a wall of text but I have tried to do some research prior to this post. I feel...

I want to convert my power supply into a "lab power supply" but a lot less simple. I just want a 12V output on it. The power supply has 2 12V rails. Is it possible to connect both rails to increase amperage? Thanks for you input.

Hello all, I am not sure if formal introductions are required on this forum, but my name is Chris and I have degrees in physics and mechanical engineering. My current job is unrelated to these fields, but I hope to get an engineering-related job soon. In any event, I have been antsy...

Hello all, I want to control a stepper motor using the computer to track the motion of a teacher in a classroom. For example i might put a webcam on the motor and control the motor to keep the camera pointing to the teacher. The teacher will be using a pen with an IR led at its top so that...

So my friends try to explain it to me and everytime they do, i come to the conclusion that they're the same. I just don't understand. If somebody studies computer science, what do they learn? If somebody studies software engineer, what do they learn?

Hey guys, I'm currently using as monitor a Flatron ez T730SH. It's been almost 4 years I have it and sometimes it would change the coloration of the whole screen (red to greenish, red-greenish over and over). Apart this I don't have any problems with it and I don't really care about the color...

I had a question and I figure you guys are the best for the task. I was wondering if theoretically you had a standard computer case, would you benefit by reducing open airspace in the case? Lets say just for example you could place a cube inside the case that doesn't touch anything, it just...

Okay so I am a freshman in college, and planning on majoring in Computer Engineering. The first semester of college was a blast, I did really well in all my classes. I loved Physics, and kinematics just clicked with me. Now comes second semester. Electricity just doesn't click with me. I...

Suppose "0" and "1" digits of binary in computers stand for 0v and 5v respectively. Further suppose "A" on the keyboard is the result of this combination "1101". Let's say there are four open switches lying down under the "A" key. When the key is pressed one of the four switches produced 0v and...

Hi A computer has some program written into its BIOS ROM which turns the hardware skeleton of a computer into a helpful machine. Is this possible to start a computer without that BIOS software using some circuitry. BIOS software is a firmware and I remember correctly I have read somewhere...

I'm a freshman in college right now and I'm still unable to decide what I want to do in the future... I think physics is my true passion, and I came into college wanting to do that. But I've been really discouraged by all the stories of physics people being unable to find jobs (and I don't...

Hello all, I'm an electrical engineering tech student working on a little side project and I can't find anything to help me with a crucial part. I have a gauge cluster out of an automobile that I want to interface with a computer to used while playing a racing game. I have a computer...

Hi I have read that a computer could retain any information as long as its user desires or unless it's nor broken. On many hard disks and USB Flash drives I have seen that the duration of how long the drives could retain the data safely is mentioned, let's say 100 years. What does it mean? To...

I am currently a sophomore engineering major thinking of switching to a math major. Math is my favorite subject, and I would like nothing more than to switch majors. However, I am a hesitant to switch because of the nature of most math careers that I know of. It seems like most math majors end...

I am deciding between an Electrical or Mechanical Engineering major, but can anyone share their work experience as an EE or ME engineer? Also, if you are willing, can you share some details such as: 1) What company you are working for 2) How flexible is your job schedule 3) What is the most...

I'm currently a second semester CE student. I have until tomorrow to choose to change for EE without affecting my curriculum. Since I've been 14, I've always wanted to go CE and wasn't really interested in the pure EE topics. When I was doing my Sciences college degree in CEGEP (Quebec system) I...

Hi Using the binary system for computing is a natural choice because of its two states: 0 and 1. But is this possible to use base 10, which is used in everyday matters, instead of base 2? Please remember that I'm neither a student of comp. science nor of science/math, in general. Thanks...
