| 1 | IS 12877 is a Indian standard that specifies the implementation of the 7-bit coded character set and its 7-bit and 8-bit extensions on a 381 mm magnetic cassette for data interchange. The 7-bit coded character set is commonly known as ASCII (American Standard Code for Information Interchange), and it is widely used for character encoding in computers and communication systems. The 7-bit extension is an enhancement to the ASCII character set that adds additional control characters and special characters. The 8-bit extension is another enhancement to the ASCII character set that allows for the representation of additional characters beyond the 7-bit range. The use of a 381 mm magnetic cassette allows for the storage and transfer of large amounts of data in a compact and portable format. | |
| 2 | IS 12877 specifies the format and structure of the data on the magnetic cassette, including record positioning and the encoding scheme used for character representation. The standard ensures compatibility and interoperability between systems that utilize the 7-bit coded character set and its extensions on a 381 mm magnetic cassette. Implementing IS 12877 helps improve data exchange and information processing efficiency by providing a standardized method for storing and transmitting data on a magnetic cassette for data interchange. IS 12877 is one of the many standards developed by the Bureau of Indian Standards (BIS) to facilitate uniformity and standardization in various fields, including information processing and data interchange. | |
