Exam 312-49v10 topic 1 question 14 discussion

The answer should be B, the first several bytes of the file. Most common example is JPEG file with a 4 byte magic byte "JFIF".

File headers typically occupy the first several bytes of a file. This section of the file contains metadata and other important information needed to identify and process the file correctly.

B > To carve a file from a block of bytes, you'll need to look for the header (and, depending on the file type, the footer) of the file. For example, the header (in hex) for a PNG file is 89 50 4e 47 and the footer is 49 45 4e 44 ae 42 60 82. https://www.usna.edu/Users/cs/wcbrown/courses/si110AY13S/lec/l31/lec.html

The answer should be B.

most likely B

B. the first several bytes of the file D is not correct because file headers typically occupy more than just a single byte. File headers contain important metadata about the file, such as its format, size, or other identifying information. This information usually takes up several bytes, not just one. That's why option B (the first several bytes of the file) is the correct answer, as it accurately reflects that file headers occupy a larger portion of the file's beginning.

The basic format of a segment is as follows: 0xff marker number (1 byte) data; size (2 bytes); and data (n bytes).

D. One Byte at the beginning of the FIle, is correct. 1 Byte = 8 Bits.

B. the first several bytes of the file
