Which one of the following statements about windows file names is false? a. names are case-sensitive b. names may contain an extension at the end c. names can be path-names, starting with a drive letter d. not all symbols can be used in a name

Windows OS does not distinguish between lower case and upper case in naming both files and folders. Names may contain .exe or any other extension at the end. We use a backlash as part of the volume names to separate the components of a path. For instance: C:\path\file. Letter C is the drive letter. Symbols like colons, ampersand, asterisk and braces cannot be used.

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.
