Describe similarities and differences between absolute filenames and relative filenames.

A path in Linux platforms is a sequence of directory names that usually leads to a directory or a file.

Simiralities

Common between these two is that all directories in the file system form a tree that begins at the root directory.

Differences

Absolute file name specifies all the directory names beginning from the root directory while relative file names specify the position of the file in the tree relative to default directory.

On Linux, an absolute file name starts with a ‘~’ or a ‘/’ while relative file name does not

An absolute path can be used from any location whereas a relative file name, a directory should be present where one should specify relative to that present working directory. 

answer: internal fragmentation is the difference between the (fixed) size of a memory hole and the data within in that memory. for example, if a 1,024 byte block of memory holds 800 bytes of data, then the 224 bytes difference is considered lost to internal fragmentation.

external fragmentation occurs when the sum of memory fragments is large enough to satisfy a request, but the holes are non-contiguous and the request cannot be satisfied. this can occur when memory is dynamically allocated and freed.
