TERM 1 File attributes DEFINITION 1 name identifier type location size protection time date user identification TERM 2 open file table DEFINITION 2 contains information about all open files TERM 3 shared lock DEFINITION 3 akin to a reader lock in that several processes can acquire the lock concurrently. TERM 4 exclusive lock DEFINITION 4 behaves like a writer lock; only one process at a time can acquire such a lock. TERM 5 mandatory file locking mechanism DEFINITION 5 Once a process acquires an exclusive lock, the operating system will prevent any other process from accessing the locked file. TERM 6 advisory file locking mechanism DEFINITION 6 it is up to software developers to ensure that locks are appropriately acquired and released. TERM 7 resource fork DEFINITION 7 contains information of interest to the user TERM 8 data fork DEFINITION 8 contains program code or data TERM 9 internal fragmentation DEFINITION 9 waste incurred to keep everything in units of blocks (instead of bytes) TERM 10 sequential access DEFINITION 10 Information in the file is processed in order, one record after the other. TERM 21 distributed information systems (or distributed naming systems) DEFINITION 21 systems that provide unified access to the information needed for remote computing. TERM 22 domain name system (DNS) DEFINITION 22 provides host-name-to-network-address translations for the entire Internet (including the World Wide Web). TERM 23 Consistency semantics DEFINITION 23 semantics that specify how multiple users of a system are to access a shared file simultaneously. TERM 24 immutable shared files DEFINITION 24 Once a file is declared as shared by its creator, it cannot be modified. TERM 25 controlled operations include DEFINITION 25 Read. Read from the file. Write. Write or rewrite the file. Execute. Load the file into memory and execute it. Append. Write new information at the end of the file. Delete. Delete the file and free its space for possible reuse. List. List the name and attributes of the file. TERM 26 access-control list (ACL) DEFINITION 26 specifies user names and the types of access a allowed for each user.
