Computer Memory Byte

Explaining Megabytes, and Megahertz in Computer Kilobits

It gets a bit confusing to laymen when faced with megabytes and terabytes and other terms when it comes to deciding on what equipment to buy.

Mega What?

A byte is the amount of computer memory needed to store data on the size of a character as an "A" So if you want to store the word "cool" on your computer, this will address 4 bytes of space.

A Kilobyte, which is a thousand bytes, equivalent to about half a page of typed text. A kilobit is one-eighth of a kilobyte, because each byte is composed of eight bits. A kilobit is a term mostly used to indicate dial-up modem speeds.

A megabyte is a million bytes, so you could store the text of a great best-selling novel thick throughout this report. A megabyte is actually 2 to the power of 20, which is 1,048,576. You can view this number reflects at a time when checking file sizes and can be confusing when trying to determine the exact size of a unit hard disk.

One gigabyte is a billion bytes, equivalent to a thousand novels, and a terabyte can hold a million novels. A gigabyte is precisely 2 to the power of 30, which is 1,073,741,824 bytes.

Text uses relatively little memory. Photographs, films and songs tend to use more. A photograph is usually used a couple of megabytes, a music track from a similar amount, and a movie can use up to a gigabyte or two, and a movie consists of a sequence of pictures, usually displayed at 25 frames per second or more.

How memory works.

Memory is very simple. It's just a huge pile of electronic switches. Each switch is on or off. Each "switch" called a little. 8 of these bits are a byte. These 8 bits are a code that the computer translates text, graphics, music, etc. For example, the letter "J" on memory is performed by the code 1001011, where 1 means that the switch is on, and means 0 is off. Each megabyte is composed of about 8 million of these microscopic switches.

Hard disk space is also known as memory, but it works a little differently, in which the bits are stored in the magnetic and not as a switch, but these bits are always transferred to the "change" the type of memory, known as (random access memory), RAM before computer uses really.

Megahertz.

The speed of a computer is measured in Megahertz, which is a measure of how many times for operations second team can do. A computer that runs at 2.8 GHz can do operations on the rate of 2800 million times per second. That's pretty fast.

RAM, memory, usually has its own code of speed that is slower than the speed of the main computer. This is because the core team has to tell memory to send data and when to stop, and at the same time you have to do other things as the calculation using these data, so that the needs of the higher speed.

The amazing thing about computers is the incredible speed that everything takes place. The fact that this rate is increasing all the time is even more incredible mind.

The future is going to be interesting!
