Question: In the LZSS Basic Algorithm used for SMS compression, what precedes a sequence of uncompressed octets in the output buffer when no match is found in the look-ahead buffer?
Option 1: Slice Descriptor indicating the start of uncompressed data
Option 2: Literal Block Identifier specifying the length of the following literal octet sequence
Option 3: End-of-Block Marker signaling the end of compressed data
Option 4: Compression Failure Indicator prompting for alternative compression
Explanation: According to the LZSS Basic Algorithm, when no match (not even a single character) is found in the look-ahead buffer, literal octets are written into the output buffer. To indicate the length of these uncompressed octets, a Literal Block Identifier is used, preceding the sequence of literal octets. This ensures the decoder can accurately interpret the compressed data stream.
