Internal and External Hard Drives
All around the world, on laptops, computers, phones, and mp3 players, electronic devices are being used to perform everyday functions. We can pull up saved passwords, applications, and saved files in a matter of seconds. But how exactly are these files saved onto these devices? What units are used to represent the amount of data being saved? How exactly do computers save documents and applications that can be sent from one computer to another?
What units are used to represent the amount of data being saved? The data used in a saved document are all measured units. “The storage capacity is expressed in terms of Bytes.” (Simply Easy Learning) After a bit, comes a nibble, which is two bits. After a nibble, is a byte, which is eight bits. These small units are not used very often in everyday life because most documents use millions of these. The bigger units are as follows;
UNITS BYTES
Kilobyte (KB) 1,024
Megabyte (MB) 1,024 KB 1,000,000*
Gigabyte (GB) 1,024 MB 1,000,000,000*
Terabyte (TB) 1,024 GB 1,000,000,000,000*
Petabyte (PB) 1,024 TB 1,000,000,000,000,000*

”A computer word like a byte is a group of fixed number of bits processed as a unit which varies from computer to computer but is fixed for each computer. The length of a computer word is called word-size or word length and it may be as small as 8 bits or may be as long as 96 bits. A computer stores the information in the form of the computer words.” (Simply Easy Learning)
How exactly are these files saved onto these devices? Every computer has an internal hard drive and a processor. What the processor is basically the eyes of the computer. It reads and processes a code of billions of 1’s and 0’s known as binary. This is also what is...
