It is very important to know the difference between a bit and a byte because these two can get easily confused. Any character you type on your keyboard is interpreted by your computer as a byte, an 8 digit binary number. But 65 is a decimal number, so if you convert it to a binary number, you get One good example is monitoring data transfer speed. When you download a file from the Internet, you probably have noticed that your browser indicates the transfer rate in KBps.
We are talking about bytes. If we see the transfer rate is for instance 46 kbps,and since we know that 8 bits equal one byte, we divide 46 by 8 and get a theoretical maximum of 5,75 Kilo Bytes per second.
A CD stores data using the binary system in the following matter: When the CD is read later, a laser follows the same spiral and reads either a pit where the light does not get reflected very well, or a smooth area called land where the light reflects very well. This system is nothing else but our good old binary system, using only two possible states, pit or land, to read and record data in binary. Storing data on a magnetic media, such as a hard drive, also uses the binary system.
In a very simplified manner of speaking, each data bit gets stored on a drive as a tiny magnetic field. Each magnetic field has two poles, North and South.
When the disk spins around and data is read by the read head, the magnetic field either has the North or the South pole aligned first. Again, only two possible stages, North or South, 0 or 1. I bought a 8. Did they sell me the wrong drive? They sold you the correct drive, but it was not labeled quite correctly.
So when they have a drive that can hold 8,,, Bytes, they just call it 8. Divide that by , and you get 8, MB. Divide that by and you get 7. It was filed under MATH. Now, there is one more thing I may have learned.
I think you may have answered that for me. Quero ser notificado de novos artigos por email. Theory without practice is paralyzing, and Practice without Theory is blindness. Enter your email address to subscribe to this blog and receive notifications of new posts by email.
The switch has only two options, on or off. The morse code is another example because It also works with only two digits, a dot or a dash. Computers can only talk in binary Electronic circuits have only 2 states off and on Each binary sequence has a special meaning The binary system is essential in technology.
