File Sizes

File size represents the size of a particular file. Mostly it is measured in Bytes or bits.

• The amount of a file size depends on the space consumed by the file.
• Every storage device is limited with a different file sizes depending on what disk space it is having.
• The different file sizes are listed on the table below.

Name	Symbol	Equal to	Binary	Number of bytes
Kilobyte	KB	1024 B	2^10	1,024
Megabyte	MB	1024 MB	2^20	1,048,576
Gigabyte	GB	1024 GB	2^30	1,073,741,824

A byte is a sequence of 8-bits. A single character or letter would use one byte of memory.

• All the alphanumeric characters are stored as 1 byte = 8-bits.
• Symbols and foreign language characters use multiple bytes.
• The file size of 26 letters stored in a file can be seen in its properties as shown below.

The Internet transfer rates are measured in Megabits per second not Megabytes per second.

• When you order a internet service your ordering 50 Megabits not Megabytes.
• And the download speed will be approximately 6.25 Megabytes.

There are different file storage tools in online having different file size limits.

In a computer we can have different sizes of files depending on the file type.

• The approximate sizes of different types of files is listed in the figure.
• And we can also sort the files based on the size of files.
