Q1 ICT-10 Lesson 1 Assessment 2

What is a program?

• A type of computer hardware

• A set of specific instructions that tells a computer what to do

• A device for scanning barcodes

• The physical components of a computer

Answer explanation

A program is defined as a set of specific instructions that tells a computer what to do. This distinguishes it from hardware, which refers to physical components, and other devices like barcode scanners.

The process of creating a set of instructions for a computer is known as what?

• Debugging

• Maintenance

• Programming or coding

• Analysis

Answer explanation

The process of creating a set of instructions for a computer is called programming or coding. This involves writing code in various programming languages to perform specific tasks or solve problems.

According to the text, computers and mobile devices perform and ______ tasks instantly.

• delete

• automate

• complicate

• analyze

Answer explanation

The correct choice is 'automate' because computers and mobile devices are designed to perform tasks automatically and instantly, enhancing efficiency. The other options do not accurately describe this capability.

What is another term for programming?

• Executing

• Compiling

• Coding

• Sequencing

Answer explanation

Another term for programming is 'coding'. While executing, compiling, and sequencing are related processes, 'coding' specifically refers to the act of writing code, which is the essence of programming.

What is the guide that programmers follow to create and develop programs called?

• Software Design Manual

• Program Development Life Cycle (PDLC)

• Coding Rulebook

• Algorithmic Procedure Guide

Answer explanation

The Program Development Life Cycle (PDLC) is a structured approach that guides programmers through the stages of creating and developing software, making it the correct choice for this question.

How many phases are involved in the Program Development Life Cycle (PDLC)?

• Three (3)

• Four (4)

• Five (5)

• Six (6)

Answer explanation

The Program Development Life Cycle (PDLC) consists of five phases: Planning, Analysis, Design, Implementation, and Maintenance. Therefore, the correct answer is Five (5).

Which of the following is the first phase of the PDLC?

• Coding

• Algorithm Development

• Testing and Debugging

• Problem Definition and Analysis

Answer explanation

The first phase of the Program Development Life Cycle (PDLC) is 'Problem Definition and Analysis'. This phase involves understanding the problem to be solved before moving on to coding and other phases.

In which phase of the PDLC do you determine the problem, need, and output?

• Maintenance

• Coding

• Problem Definition and Analysis

• Algorithm Development

Answer explanation

The Problem Definition and Analysis phase is where you identify the problem, assess needs, and outline expected outputs, making it the correct choice for this question.

What is an algorithm?

• A programming language

• The logical sequence of steps and procedures to solve a problem

• A diagram that represents a program

• An error in a program

Answer explanation

An algorithm is defined as the logical sequence of steps and procedures to solve a problem. This distinguishes it from programming languages, diagrams, or errors, which are not the essence of what an algorithm represents.

Which two ways are commonly used to represent a program's algorithm?

• Python and C++

• A flowchart or a pseudocode

• Coding and Debugging

• A computer and a smartphone

Answer explanation

A flowchart or pseudocode visually or textually represents an algorithm's steps, making it easier to understand the logic before coding. In contrast, programming languages like Python and C++ are used for implementation, not representation.
