1024 characters is 1,000 bytes, or one kilobyte.

A byte is 8 "bits", meaning that 8 switches which work together to define data. One character can be represented by a byte. A "kilobyte" is 1024 bytes A "megabyte" is 1024 squared A "Gigabyte" is 1024 cubed 200 Gigabytes would be 200*1024*1024*1024 bytes. To give it some meaning, most books are between 170,000 and 200,000 characters (bytes)
1024
If you are storing ASCII character set, 5 x 1024 x 1024 x 1024 characters can be held. If you are storing UTF-8 character set(s), 5 x 1024 x 1024 x 1024 / 8 characters can be held. English is a ASCII character set. Japanese and Nepalese can be UTF-8 character set(s).
A gigabyte is approximately one billion characters.
If you're referring to kilobyte, then it contains 1024 bytes and if the characters are the standard ASCII character set where 1 character is 1 byte, then a kilobyte would have 1024 characters.
The metric unit to record data are bytes. There are 1024 bytes in a kilobyte, 1024 kilobytes in a megabyte, etc.
A chunk of data measuring 1024 bytes is equal to exactly 1 kilobyte. These are units of measure for very small units of data.
4kB = 4 * 1024 = 4096
I'm going to answer the queestion you already answered ...3 gigabytes...
Originally, 1024 bytes was called a kilobyte, since 2^10 is 1024, which is essentially the same representation as 10^3 (1000). However, because this terminology caused confusion, the International Eletrotechnical Commission decided to introduce a new term for 1024 bytes, called a kibibyte. If you ask a computer purist, 1024 bytes is a kilobyte, which logically makes sense, because computers operate in binary, not decimal. If you ask newer computer users, they will not know what to call 1024 bytes, or they will call it a kibibyte, which is formally correct.
A standard floppy disk (those still found today) is 1.44MB in size. There's 1024 kilobytes in a megabyte, and 1024 bytes in a kilobyte. If the size was exact usable space, it would be 1.44 * 1024 * 1024, which is 1509949 bytes. Since it's not the usable size, the USABLE size of a floppy is 1440 * 1024, or 1474560 bytes. Each ASCII character is one byte, so a floppy can hold many characters.
