• Nibble: A group of 4 bits.
• Byte: A group of 8 bits, representing the smallest unit capable of representing a data item or character.
• Word: A group of bits processed as a unit, with the size varying between computers but constant for each individual system.

Ports

• Ports are specialized docking points on a computer, facilitating connection to external devices using cables.
• Examples of external devices connected via ports include mice, keyboards, monitors, microphones, and speakers.

Software

• System Software: Consists of programs designed to manage the computer itself, including operating systems like Windows, Linux, UNIX, Android, and iOS.
• Application Software: Encompasses programs used for specific tasks, such as word processing, spreadsheets, payroll and inventory management, and entertainment applications like games.

Operating Systems

• Operating systems act as the intermediary between software and computer hardware, managing and controlling the overall resources and operations of a computer.

Programming Languages

• Programs are sets of instructions executed by a computer.
• A Programming Language (PL) is a standardized communication method for expressing instructions to a computer. Examples include: Visual Basic, C++, C#, Java, and Assembly Language.

Programming Language Concepts

• Syntax: Specifies the rules that define the correct structure and format of statements or expressions in a programming language.
• Semantics: Focuses on the meaning and interpretation of code, ensuring it behaves as intended and produces the desired results.
• Grammar: Encompasses both syntax and semantics, providing a comprehensive set of rules for writing and executing code.

Applications of Programming Languages

• Software Development: Widely used for creating software applications, system software, and other computer programs.
• Web Development: Languages like HTML, CSS, and JavaScript facilitate the creation of dynamic and interactive websites.
• Data Science and Analytics: Languages such as Python and R are essential for data analysis, interpretation, and machine learning model construction.
• Scientific Computing: Fortran and MATLAB aid in solving complex mathematical and scientific problems.

Problem Statement (Example)

• Problem: Calculate the average grade of 10 students.

Pseudocode

• An English-like representation of the logical steps involved in solving a computer problem.
• Example:
  • Initialize the sum to 0.
  • Repeat for each student (1 to 10):
    • Read their grade.
    • Calculate the sum by adding the current grade to the existing sum.
  • End the loop.
  • Calculate the average by dividing the total sum by 10.
  • Print the average grade.

Pseudocode (Example)

• Problem: Count the number of characters in a string.
• Process (High-Level):
  • Read one character at a time.
  • Increment a count for each character read.
  • Repeat the above steps until there are no more characters.
• Process (Refinement):
  • Initialize the count to 0.
  • Repeat the following steps:
    • Read one character at a time.
    • If a character is found, add 1 to the count.
  • Continue the loop until there are no more characters.

Coding and Documentation

• In this phase, the program is written using a specific programming language like C, C++, Java, etc., based on the defined steps from the previous phase.

Testing and Debugging

• This phase involves thoroughly testing the code to ensure it correctly solves the problem for various input values.
• The goal is to identify and fix any errors or bugs that may exist in the code.

Syntax

• Syntax refers to the grammatical rules governing the structure and format of valid statements or expressions within a programming language.

Flowcharts

• Flowcharts are visual representations of the steps involved in a process, used for organizing and sharing ideas.
• They are used across many professions, including programmers, engineers, scientists, business managers, and healthcare workers.

Flowchart Guidelines

• Flowcharts should have a single start and stop symbol.
• On-page connectors are referenced using numbers.
• Off-page connectors are referenced using letters.
• The general flow of the chart is typically from top to bottom or left to right.
• Arrows should not cross each other.

Flowchart Symbols

• Start/End: Represents the beginning or end of a process.
• Process: Indicates a step in the process that involves some action.
• Input/Output: Indicates data being entered into or output from the system.
• Decision: Represents a choice or branching point in the process.
• Connector: Connects different parts of the flowchart, especially when the steps are too long to fit on a single page.

Converting Feet to Centimeters (Activity)

• Algorithm:
  • Input the length in feet.
  • Multiply the length in feet by 30.48 to calculate the length in centimeters.
  • Print the length in centimeters.

Calculating Rectangle Area (Activity)

• Algorithm:
  • Input the width (W) and length (L) of the rectangle.
  • Calculate the area (A) by multiplying L with W.
  • Print the area (A).

Calculating Employee Net Pay (Activity)

• Algorithm:
  • Input the hours worked, rate, and deductions.
  • Calculate gross pay by multiplying hours worked with rate.
  • Calculate net pay by subtracting deductions from gross pay.
  • Print the net pay.

Decision Making in Flowcharts

• Computers are integral in performing various types of analysis.
• The decision symbol in flowcharts signifies a point where a condition is evaluated.
• Steps:
  • Perform a test on the condition.
  • If the condition is true, branch to the 'Yes' steps.
  • If the condition is false, branch to the 'No' steps.

Determining Student Grade (Example)

• Algorithm:
  • Input the student's grade.
  • Compare the grade to the passing grade (75).
  • If the grade is greater than or equal to 75, print "Passing."
  • Otherwise, print "Failing."
