DU just reached a megabyte!

[evlbstrd]

Hooray, 1024! Hooray beer!

[Omphaloskepsis]

1. I don't know what the fuck you are talking about..

I will have a smoke and throw a empty beer can at my sister. A milestone is a milestone.


edit -- 1024 nerdy RAM numbers.

[evlbstrd]

3. Number of donations.

Kiss your sister for me.

[NNN0LHI]

21. I am going to have my smoke now

Throw an empty beer can at your sister for me too.

2. Hooray Beer!

:toast:

[evlbstrd]

4. Thank you!

[Dick Diver]

5. ummm, 1024 is not a megabyte

It's a kilobyte.

[Random_Australian]

6. Wow, sharp! (sort of).

Welcome to DU!

[evlbstrd]

10. d'oh!

I majored in art.

[hootinholler]

13. Agreed, but

1000 is a kilo. 1024 is a convienient representation of 1000, base 2 or 10000000000 base 2, which is the overflow condition from 1111111111 base 2, an engineering convenience if you will. It's comonly called a binary K.

Nothing to do with bytes or bits.

26. Ummmm 1024 kilobits is a megabyte.

[whistle]

7. Correction, I believe that would be one kilobyte....

....kilo = 1,000
....mega = 1,000,000

Now, someone please explain what a byte is and please don't say 8 bits or 16 nibbles. :hippie:

[evlbstrd]

11. Now you've gone and done it.

[Crabby Appleton]

8. The binary prefixes used in computing

kilo = 2¹⁰ = 1,024
mega = 2²⁰ = 1,048,576

9. my head is hurting

[whistle]

12. Thank you and the byte would be 2 (3) = 8 bits so what is a nibble

[hootinholler]

14. A byte is 2^8

Edit to say a byte is an amount of memory that can hold values up to 2^8.

Maximum count is 256 base 10.

A nibble is 2^4 or 4 bits each bit is one place base two.

-Hoot

[whistle]

15. the 2 (hat) 8 symbol equals what? That is not the same as the

exponential value stated earlier then, correct? Now to really make myself dizzy, what's a word in digital computing? (When the student is ready the teacher will appear)

[hootinholler]

16. It's ^ simply a shorthand to enter exponentiation

So that should be read as 2 to the 8th.

A word is an arbitrary length, based on the width of the part of the processor that holds numbers while you 'arithmetic' them, it also usually indicates how much memory can be addressed before memory banking or swapping schemes come into play. Usually words are a multiples of 8, but, I've worked on machines with a 35 bit word size.

In intel architecture, word sizes started at 8 bits, and now are 64 bits on the most modern chips. (Intel may have 128 bit word processors, I don't keep up with them closely)

19. Please bear with me, so a byte becomes 2x2x2x2x2x2x2x2=256bits

...is that correct? The nibble then is 2x2x2x2= 16bits. Ah ha. It's scary to think Diebold could have digital illiterate people like me maintaining and even programming the electronic voting machines. Yikes! Thanks for the digital lesson.

Oh, I don't seem to have the ^ key on my keyboard....oh wait a minute it's above the 6 like so ^. Does that mean if I enter a 2^8 in a program (i.e Excel) it will perform the exponential function correctly? Guess I should try it..... oh wow, it works!!!!:bounce:

I owe you a root beer Hoot :toast:

[hootinholler]

23. Not quite, it's base 2 arithmetic.

One bit can be a one or a zero, and can hold 2 values. A byte is 8 bits hooked up together and can hold 256 unique values, 0 through 255 inclusive.

Consider a byte set to: 00000000
Then if we keep adding 1 to the value it becomes 00000001, 00000010, 00000011, ... 11111110, 11111101, 11111110, 11111111
Which are decimal (base 10) values: 0,1,2,3,...,252,253,254,255

256 bits can hold a fairly big number, 2^256 = 33554432

So, 2^(number of bits) is how many values other than 0 a specific memory width can hold.

24. Ahaaa, I understand, but now I am on the cusp of IOL....

...information over-load. I need an incubation period for it all to hatch and bloom. Thanks for all of your help.

[hootinholler]

25. Well if you really have it you'll spot my error in the above post.

It's really simple think digits. Base 10 how many digits does it take to be able to express 1000 values? 3: 000-999 In base 2, it takes 8 digits to express 256 values.

Next lesson is octal (base 8).

17. A computer's word length

depends of the architecture (i.e. hardware) of the computer and represents the size in bits of data that is manipulated as a group. For instance in x86-based computers it is generally the size of the CPU's registers 16, 32, or 64 bits.

[whistle]

20. Great people here on DU, I think there are enough computer

...literate folks here that if we all took one voting precinct in the country this November, the electronic voting machine cheating could be at least nuetralized if not not even overturned. Thanks Crabby.

[Deja Q]

18. Will somebody put this kilobyte post in the lounge?

megabyte = one thousand twenty four kilobytes.

kilobyte = one thousand twenty four bytes.

[Wonk]

22. one byte = 8 bits
