Computer Experts, Please HELP!
 

Here are three simple questions for you:

1. Define and explain MB? [please give an intelligent and insightful answer to this question, do not just write MB= megabyte]

2. Define and explain MHz? [please give an intelligent and insightful answer to this question, do not just write MHz= megahertz]


3. Why is a computer with 64 MB RAM is FASTER than that with only 24 MB RAM when MB is not a unit of speed?? [please give an intelligent and insightful answer to this question, do not just explain because 64 is greater than 24]

Thanks

P.s I'm serious about this shit, please help me if you can...

You are one stupid fuck

The answers to all your questions.....

I'll answer these questions in excrutiating detail to rival that of Patterson and Hennessey's Computer Organization and Design if you swear on the Grandfather Spirit to never ask questions like this in these forums ever again.

i swear.

I'm not that dumb to ask those questions. but some fucker ask me this at another forum and i don't know how to answer him.

where are you?

damn, i'm going to fuckedcompany now.

:)

Now,even I feel smart.

Megabyte. A Byte is a "word" of 8 bits. 1 Bit is the smallest bit of information. It takes 8 bits to make one byte. Think of a bit as a letter in the alphabet, the byte is the word. A MegaByte is a Millions Bytes. A GigaByte is a thousand bytes.

A Hertz is a measure of unit for speed. 1 Hz (Hertz) is equal to one clock (one instruction) per second. So the higher the Hz rate, the more instructions are being processed per second. It's like speed in a car. We calculate how many miles or kilometers we do in an hour, this measurement is done over a timespan of 1 second.

RAM is essentially like deskspace. If I gave you a model car to assemble, and gave you a small TV Tray to work on, or gave you a large table to use, you'd probably be more efficient using the large space because you can have everything you need laid out there, and not somewhere else like in the box (which would be let's say your hard drive or CD-Rom).

It's the easiest analogy to use.

Cya!

A megabyte is a unit of storage that is equal to 1,024 units of 1,024 bytes. When purchasing things like hard drives, different companies occasionally round to 1,000.

Megahertz measures cycles per second. There is a lot more involved such as the rising and falling sides of a cycle and bus speeds and stuff, but it's basically a measure of how many opportunities per second your processor gets to make calculations. 1 Megahertz = 1 million cycles per second.

RAM is almost pure electricity. When information is stored in RAM it is available for retrieval and manipulation at a much faster rate than if the information has to be read from some physical medium. It doesn't actually make the computer faster but it allows the computer to store more information in its faster electrical form which makes calculations faster.

Just a little nitpick on a typo:
A Byte is 8 Bits
A KiloByte is 1024 Bytes
A MegaByte is 1024 KiloBytes
A GigaByte is 1024 MegaBytes

1. Define and explain MB? [please give an intelligent and insightful answer to this question, do not just write MB= megabyte]

The concept of a "mega" byte is the convenient approximation of very large base2 numbers to the more common conceptual context of the base10 number system. A bit, for example, is 2^1 or two to the first power. It can be on or off, hence it has two possible values. It's the simplest unit of complexity in the binary system. Most computers today are semi-conductor based and their switches can only be on or off. So, not only is on/off simple in terms of being easy to reckon with, it also maps to the actual microcircuit. This fact is very important when adding more circuits.
8 bits, or switches, running in parallel, provide a range of 256 possible values (2^8). a byte could be thought of as all the information those switches can hold in a frozen instant.

often we'll need to store off that info (or those instructions, or whatever that hot information is), to use a moment later.

which is why our microcircuit, or "microprocessor" has a tiny little cache that is very, very close by. it's often only a "MB" or less in size. This is enough to hold a great diversity of processor states and configurations. It can hold large segments of machine code that will probably be repeated. It's an "order of magnitude" faster than RAM. Some processors have multiple caches (l1,l2) etc, that are at different distances from the microcircuit- the closer they are, the faster they reload state, and the less capacity they generally have.

hard drives use magnetic storage, not circuits, and cd drives laser etch the information, etc...

Often you'll want to save the current state of your switches because you need to use them for something other than what they're being used for.

but how large is a megabyte, really? if 2^20 is roughly 1,000,000- is 2^28 a useful answer? nope. 2^28 is actually a smaller number than four bytes. We're talking 256^1048576.

A megabyte is an enormous amount of state information. You might be able to save a lifetime of simple decisions in a megabyte, given some serious time to think about how they might be encoded.

2. Define and explain MHz? [please give an intelligent and insightful answer to this question, do not just write MHz= megahertz]

Well, now I'm kind of tired after explaining megabytes, and someone already did a pretty good job with this one.

Hertz, yeah. That guy. Heinrich Hertz. Came up with the measure of frequency. How often does something happen? Oh, that's easy, it happens X times per Y duration. Pretty simple nowdays.
What other people said regarding this sums it up. I could talk about clocks. I could really really drill your skull talking about clocks. And I know in my heart and soul that you do not want to know about stepping clocks.

Have you ever seen an oscilloscope? Electronic waves? The heart rate machine, the one that goes ping? Hertz.

Hey, I've got a question for you: Have you ever eaten a Hertz donut?

3. Why is a computer with 64 MB RAM is FASTER than that with only 24 MB RAM when MB is not a unit of speed?? [please give an intelligent and insightful answer to this question, do not just explain because 64 is greater than 24]

The desktop analogy is more than adequate. I should probably tell you about memory paging, context switching, multithreading, and multitasking, but you don't want to know, do you?
