1. True / False

T / F (a) Recursion is a form of iteration.

T / F (b) A two-pass assembler uses the first pass to build a symbol table.

T / F (c) A Turing Machine is an abstract model of computation suitable for mathematical analysis.

T / F (d) One of the critical responsibilities of an operating system is to provide a convenient fiction for the user in the form of an interface.

T / F (e) Some problems are impossible to solve with computers.

T / F (f) An advantage of high-level languages is that the programmer must manage the movement of data items between memory locations.

T / F (g) Python is the most appropriate language choice for any programming problem.

T / F (h) Racket is a functional programming language.

T / F (i) During lexical analysis the compiler converts the program from a sequence of characters to a sequence of tokens.

T / F (j) Programming languages are too complex to be created by individuals, and so are always designed by committee.

T / F (k) BNF grammars are used to define the semantic structure of programming languages.

T / F (l) Encryption technology serves two purposes: security and authentication.

If you post more than 4 parts in a question, as per chegg guidelines I ahve to solve only first 4 parts.

(A) False

Recursion is the process where a function calls itself.

Iteration is where a loop iterates many times to solve a poblem.

Iteration is an artifact of programming and inherently constructive in nature, but recursion is not necessarily constructive.

(B) True

In the first phase, it does the following tasks:

(C) False

It is amathematical model which uses a strip of tape to manipulate the symbols based on the rules and helps to perform the logic of an algorithm.

(D) True

Operating system acts as an interface between kernel and user by roviding an interface which is user friendly.
