Programmers compile a list of instructions to build their applications. These instructions are typically grouped into units of code called ____________________.

Like a loop, a recursive method must have a way to control the number of times it ___________________.

Fill in the blank(s) with the appropriate word(s).

Which of the following statements is false?

a) A concept called threads enables the operating system to run parts of an app concurrently. Though all of these tasks can make progress concurrently, they may do so by sharing one processor core. b) With multicore processors, apps can operate truly in parallel on separate cores, possibly increasing the app’s performance substantially. c) Parallelizing apps and algorithms to take advantage of multiple cores is difficult and highly error prone, especially if those tasks share data that can be modified by one or more of the tasks. d) A benefit of functional programming is that you can easily ask the library to perform a task with parallel processing to take advantage of a processor’s multiple cores. This is the purpose of CLINQ (Concurrent LINQ)—an implementation of the LINQ to Objects extension methods that parallelizes the operations for increased performance.
