AP Computer Science Principles Vocabulary Exam Review Algorithm - Answer-At its core, an algorithm is really just a generalized, conceptual solution to a problem that can later be implemented in some real-world form like a computer program. Application Program Interface - Answer-Application program interface (API) is a set of routines, protocols, and tools for constructing software applications. An API specifies how software components should interact. In addition, APIs are used when pro...

MODULE 7: FILE SYSTEMS COP4600 PRACTICE STUDY GUIDE EXAM Explain the image on 'shared files & links' slide - CORRECT ANSWER-- i-node array holds i-nodes to data blocks located on disk for specific file - a single file's i-node can point to multiple different data blocks - data does not have to be ordered or sequential - a directory block has an i-node that points back to the i-node array, which then points to the file data - multiple directories can point to the same i-node to acc...

absolute memory addressing - using memory address operands that refer to actual physical memory locations; this method requires process offsets addressable memory - he highest numbered storage byte that can be represented in a CPU or computer; usually determined by the number of bits used to represent an address advantage of allocation unit size - using a smaller unit size wastes less space when there is a lot of small files because less storage is allocated to one file allocation units - ...
