What is the Difference between Ansi, Utf-8, Unicode and Ascii
As all of us know that Encoding is a vast field of computer and telecommunication is not possible without encoding. In fact, the concept of encoding was evolved when people started thinking about communicate with each via digital devices. This was not possible without character oriented information. This character oriented information is based upon numeric and alphabetic characters and it has become a useful tool to process, store and communicate information via digital devices. With the passage of time, the field of encoding has been developed very much and today various type of computer encoding has came in front of us. These different types of computer encodings are named as Ansi, Utf-8, Unicode and Ascii. Let’s see the difference between these famous encoding types.
ANSI
ANSI is such type of computer encoding scheme that consists of symbols, numbers and letters. Total count of these letters, numbers and symbols that are used in making of ANSI encoding are 256. If anyone want to get these specific characters used in formation of ANSI encoding, he may found them on page umber 437 of IBM codes. The examples of most common software that are based upon ANSI coding are Unix and MS-DOS. ANSI Coding offers color scheme of 8 plus 16 background and foreground colors.
ASCII
ASCII is also a famous computer encoding format but with advancement in scheme than ANSI. ASCII is the abbreviation of American Standard Code for Information Interchange and it was designed on the basis of English Alphabets. The simple definition of ASCII encoding is that, this is the standard coding scheme for every computer and communication device that helps in representing text.
Unicode
Unicode is also a computer encoding standard that is used for representation of text in most of the writing software. Today, it has been widely developed and covers 100 scripts. If we talk about number of characters include in this text encoding system, we see that there are more than 110,000 characters in this encoding standard. All latest operating systems and modern computer languages use Unicode as text encoding format.
UTF-8
UTF-8 is renowned character encoding that is used in implementation of ASCII and Unicode. It has capability to show every individual character in Unicode, so it is also known as variable width encoding. Today, most of the web pages are based upon UTF-8 character encoding.
ANSI vs UTF-8 vs UNICODE vs ASCII
ANSI and ASCII are very closely related character encoding schemes. The difference is only that, ANSI is the flexible form of computer encoding scheme because it contains symbols as well that are necessary for representation of drawing. Up till 2998, ASCII was the dominating character encoding but now UTF-8 is ranking first as now more than half of web pages are designed on UTF-8. Unicode is a vast encoding standard that consists of 110,000 characters in 100 scripts.
