To enforce Isolation (through mutual exclusion) among conflicting transactions. . To preserve database consistency through consistency preserving execution of transactions.. Parallel structure (also called parallelism) is the repetition of a chosen grammatical form within a sentence. By making each compared item or idea in your sentence follow the same grammatical pattern, you create a parallel construction. What Is Parallel Structure?. Parallel structure involves putting together elements of similar structure to achieve balanced writing.. Parallelism is an effective literary and rhetorical device that enables a writer to convey an importance, to explain an idea or to draw a comparison. (In fact, that sentence just used parallelism.)

Posix Threads (Pthreads) Concurrency Chapter 26 Abstraction: Threads Here we introduce a new abstraction for a single running process: that of a thread. The state of a single thread is thus very similar to that of a process. It has a program counter (PC) that tracks where the program is fetching instructions from
