1.
Computer Science is a cluster of related scientific and engineering disciplines concerned with the study and application of:
Correct Answer
C. Computations
Explanation
Computer Science is a field that focuses on the study and application of computations. Computation refers to the process of performing calculations or solving problems using algorithms and mathematical models. In Computer Science, computations are used to design and develop software, analyze and manipulate data, create artificial intelligence systems, and solve complex problems in various domains. Therefore, the answer "Computations" accurately represents one of the core elements of Computer Science.
2.
The Theory of Computation is a scientific discipline concerned with the study of
Correct Answer
B. General properties of computation be it natural, man-made, or imaginary
Explanation
The correct answer is "general properties of computation be it natural, man-made, or imaginary." This answer accurately describes the scope of the Theory of Computation, which is concerned with studying the general properties of computation in various contexts, whether they are natural, man-made, or imaginary. This encompasses the study of computation in natural systems, such as biological processes, as well as man-made systems like computers, and even hypothetical or imaginary systems.
3.
The foundations (or theory) of computer science can be partitioned into two sub-disciplines: one concerned with the
Correct Answer
C. Theory of Computation with the Theory of Programming
Explanation
The correct answer is "Theory of Computation with the Theory of Programming". The question is asking for the two sub-disciplines of computer science. The options "Theory of Compilation with the Theory of Programming", "Theory of Combination with the Theory of Probability", and "Theory of Complexity with the Theory of Progressive" do not match the correct sub-disciplines. The correct sub-disciplines are the Theory of Computation and the Theory of Programming, which are closely related in computer science.
4.
The Theory of Computation is also concerned with finding the
Correct Answer
B. Most efficient methods for solving specific problems
Explanation
The Theory of Computation focuses on finding the most efficient methods for solving specific problems. This means that it aims to discover algorithms and techniques that can solve a given problem with the least amount of time, space, or computational resources. By identifying the most efficient methods, the Theory of Computation helps in optimizing the performance and effectiveness of problem-solving approaches in various fields such as computer science and mathematics.
5.
The nature of efficient computation (and computation in general) is indeed the formative question of the
Correct Answer
A. Theory of Computation
Explanation
The nature of efficient computation is the central focus of the Theory of Computation. This theory explores the fundamental principles and limitations of computation, including the study of algorithms, complexity theory, and the design of efficient computational systems. It aims to understand what can and cannot be computed, and how to optimize computational processes. The Theory of Computation provides a framework for understanding the capabilities and limitations of computers and plays a crucial role in computer science and related fields.
6.
Form the most important class of automata between finite-state machines and Turing Machines.
Correct Answer
C. Pushdown Automata
Explanation
Pushdown Automata form the most important class of automata between finite-state machines and Turing Machines. While finite-state machines have limited memory and cannot handle nested structures, pushdown automata can use a stack to store and retrieve information, allowing them to handle more complex languages. Pushdown automata are more powerful than finite-state machines but less powerful than Turing Machines, which have an infinite tape for storage. Therefore, pushdown automata fill the gap between these two types of automata and are widely used in the field of formal language theory and automata theory.
7.
Comprises a finite-state control, a semi-infinite input tape, and a semi-infinite storage tape.
Correct Answer
B. Pushdown Accepter
Explanation
A pushdown accepter is a type of automaton that consists of a finite-state control, a semi-infinite input tape, and a semi-infinite storage tape. It is capable of recognizing context-free languages by using a stack to store and retrieve symbols. The pushdown accepter can transition between states based on the current input symbol and the symbol on top of the stack. If the input is processed completely and the stack is empty, the pushdown accepter accepts the input. Therefore, the given explanation aligns with the characteristics of a pushdown accepter.
8.
The character empty null string(triangular shaped) is used to indicate a _____________ in a tape cell.
Correct Answer
D. Blank
Explanation
The character empty null string (triangular shaped) is used to indicate a "blank" in a tape cell.
9.
is a place where input letters or other information can be stored until we want to refer to them again.
Correct Answer
C. A or B
Explanation
The correct answer is A or B because both the terms "Pushdown Stack" and "Pushdown Store" refer to a place where input letters or other information can be stored until we want to refer to them again.
10.
Adds a new letter to the line and it is placed on top of the stack, and all other letters are pushed back or down accordingly.
Correct Answer
D. Push
Explanation
The given explanation suggests that when a new letter is added to the line, it is placed on top of the stack. This action causes all other letters to be pushed back or down accordingly. The word "Push" is the correct answer as it accurately describes this process of adding a new letter to the line and pushing the existing letters back or down.
