Homework Statement A computer disk is made by focusing light to a spot whose diameter is comparable to the optical wavelength. Find the number of bits that can be stored on a 10cm diameter optical disk using an infrared laser. Homework Equations Lamda λ = diametre of laser The...

Problem : a) A good sized English book has about 100000 words. If an average English word is six characters long and each character needs 1 byte, show that the book can be stored in 600 kbyte of memory and show that the text takes nearly 5 seconds to be transmitted at 1 Mbit s-¹. Show that it...

Homework Statement /* * evenBits - return word with all even-numbered bits set to 1 * Legal ops: ! ~ & ^ | + << >> * Max ops: 8 * Rating: 2 */ int evenBits(void) { return ?; } The Attempt at a Solution I have no idea! What I originally thought was that I would...

Homework Statement Player 1 starts by choosing 0 or 1, then player 2, repeat infinitely many times and stick a decimal point in front and see the bit string as a real number between 0 and 1. If it's rational player 1 wins, irrational player 2 wins. Does either player have a winning strategy...

Hello, I have a curiosity. With a finite number of bits, say 5, you can represent 2^5 items. If B = {00001, 00010, 00100, 01000, 10000} is the set of these 5 bits, you can combine them to represent the power set of B, with cardinality 2^5. With a countably infinite number of bits, you...

I just bought an SD card for my camera, talk about things getting smaller i could hardly hold the big bit that the little bit had to be pushed into, now i am baffled is it the big bit that holds the 1 gig memory or the little bit, if it is the little bit why have the big bit, or is that for...

Why in 2's complement the range of numbers that can be represented with 4 bits are from -8 to +7? Wouldn't the numbers with 4 bits be till 15? I am confused.Please help me out. -Thankyou

Hi all, quick question here. As part of a sophomore seminar class, I have this little task to complete. I currently want to send a series of 4 bits through an IR LED that will reach a GaAs photo transistor. What I'm doing is using a shift register to load in the binary value (via a parallel...

Hi, This is a re-launch of an earlier question that I have narrowed down to just part a). I have also added my musings on it so far. This is all very new to me (and we haven't been given much in the lectures to go by [nor is there a course text]). I'd appreciate some help asap! Homework...

Here is an article about the Holographic Principle found on Wiki, then please read my comments below: If new bits can actually create area (volume as described above), maybe the universe is expanding because its bits are increasing? Maybe since humans have developed computers and we are...

Are quantum bits just a form of a ternary numeral system? If something can be 0, 1, or both simultaneously, isn't the superposition just another equal value? If the superposition of 0 and 1 were literally individual, combined, and possibly something different simultaneously, then it seems...

Hey there I'm studying for end of year exams and can't figure out how to do these 2 questions: 1) Express \log_{10}(2\sqrt{10}) - \frac{1}{3}\log_{10}0.8 - \log_{10}(\frac{10}{3}) in the form c + \log_{10}d 2) Simply finding the cube root of a complex number in polar/cartesian form ie...

If I have a string of 19 continuous bits 'high' followed by a bit 'low', how do I calculate the DC Offset if the pattern is repeated? Is it just [(19 - 1)*(the amplitude)]/(20)? Thanks for the help. Chris

MATLAB! Question! Hi, http://www.geocities.com/spoutveg10/matlab.JPG Does anyone know what the "fuzzy" bit at the tops of the spectrum are? I went for a complete guess out of distortion or noise. Any elaboration as to why? I connected up a Binouli random data source with a sample time...

How do they make them so that these exquisite notes come from them, i mean they are flimsy bits of wood and tensioned strings, is there a (science) behind it ?

Why do some photos have black squares cut out of them from hubble, like this: http://nssdc.gsfc.nasa.gov/image/astro/hst_antennae_9734a1.jpg

I got called into work today on my day off, and is was **** cold, it is freezing fog outside and a max of 10c inside, how can i keep my bits warm ?

When we stretch a spring like the one on this link, http://auto.howstuffworks.com/car-suspension3.htm it tends to obey hookes law (up to a point) - does this mean, like when wires are stretched (which also obey hookes law) the metal of the spring is actually streching and not just being moved...

I often think about this subject, would it be a fair assumption to say that our electronic bits are a equivalent and more simple "thing" of that we assume to be the more elementar "particle" of the universe, a string, acording to the theory, it is the vibrating state of certain string that...

Hello everyone I am enrolled in a AP Computer Science course. Currently we are learning about bits and bytes. Could someone please explain the concept of bits and bytes. For example, here are some questions that I have tried doing: 1. 16-bit binary numbers can be used to represent all...

Hi all! I'm in serious need of some help. The question: How many binary strings of length 10 contains exactly two "01"? My idea was to weld together 4 bits to 2 "01". That way, there's \frac{8!}{2!} strings with at least 2 "01". But there are a bunch of strings with more than 2 "01" in...

i had a problem earlier that russ,zantra and greg helped me out of, basicaly the program that drives my scanner had bits missing, as i NEVER load anything on my computer, apart from the os or download from the net, apart from saving certain items to MY DOCUMENTS, how can this happen? my...
