What is the extended ASCII character set?
What is the extended ASCII character set?
A set of codes that extends the basic ASCII set. The basic ASCII set uses 7 bits for each character, giving it a total of 128 unique symbols. The extended ASCII character set uses 8 bits, which gives it an additional 128 characters.
How many characters are in the extended ASCII character set?
256 different characters
Extended ASCII is a version that supports representation of 256 different characters. This is because extended ASCII uses eight bits to represent a character as opposed to seven in standard ASCII (where the 8th bit is used for error checking).
Is extended ASCII still used?
ASCII is still used for legacy data, however, various versions of Unicode have largely supplanted ASCII in computer systems today. But the ASCII codes were used in the order-entry computer systems of many traders and brokers for years.
What are the ASCII and extended ASCII encoding scheme?
ASCII encoding scheme uses a 7-bit code and it represents 128 characters. Its advantages are simplicity and efficiency. Extended ASCII encoding scheme uses a 8-bit code and it represents 256 characters.
Why would extended ASCII be used?
For programming languages and document languages such as C and HTML, the principle of Extended ASCII is important, since it enables many different encodings and therefore many human languages to be supported with little extra programming effort in the software that interprets the computer-readable language files.
Why did the use of extended ASCII codes cause problems for users?
(b) Why did the use of extended ASCII codes cause problems for users? There was no standard. Different manufacturers used them to represent different characters e.g. accented letters in French. There needed to be more characters to cover all the languages on earth.
What is the most common extended ASCII set quizlet?
The most common extended ASCII set is the Unicode. It has become the standard on the Internet and includes codes for most of the world’s written languages, mathematical systems, and special characters.
How many bits does the extended ASCII character set use and why is this necessary?
8-bits
The Extended ASCII character set uses 8-bits, which gives an additional 128 characters (i.e. 256 in total). The extra characters represent characters from foreign languages and special symbols such as Ö € or →.
