How many ASCII characters can be stored in 1KB of memory?

1KB memory can store up to 1024 ASCII code characters. Because one ASCII code occupies one byte and one Chinese character internal code occupies two bytes, 1KB is 1024 bytes, so 1024 ASCII code characters can be stored. , 512 Chinese character internal codes.

How many ASCII code characters can be stored in 1KB of memory at most?

ASCII is a seven-bit code, and a total of 8 bits are used to store it. The highest bit is always 0.
1kb=1024b
1b=8bit
So 1kb can store up to 1024 ASCII codes.

Simply put, an ASCII code occupies one byte, and a Chinese character internal code occupies two bytes. 1KB is 1024 bytes, so 1024 ASCII codes can be stored. Characters, 512 Chinese character internal codes.

ASCII ((American Standard Code for Information Interchange): American Standard Code for Information Interchange) is a computer coding system based on the Latin alphabet, mainly used to display modern English and other Western European languages. It is the most common information exchange standard and is equivalent to the international standard ISO/IEC646. ASCII was first published as a standard type in 1967, and was last updated in 1986. So far, a total of 128 characters have been defined.

Extended information

In computers, all data must be represented by binary numbers when stored and operated (because computers use high and low levels to represent 1 and 0 respectively), for example , 52 letters (including uppercase letters) such as a, b, c, d, numbers such as 0 and 1, and some commonly used symbols (such as *, #, @, etc.) must also be stored in binary numbers when stored in the computer. Of course, everyone can agree on which binary digits are used to represent which symbol (this is called encoding). If everyone wants to communicate with each other without causing confusion, then everyone must use the same encoding rules. , so the relevant standardization organizations in the United States introduced the ASCII encoding, which uniformly stipulated which binary numbers should be used to represent the above common symbols.
