Basics of Computer

• A computer is an electronic device that receives, stores, processes, and outputs data.
• It performs a wide range of tasks, from simple calculations to complex artificial intelligence.
• Computers consist of hardware (CPU, memory, storage, input/output devices, peripherals) and software (operating system, applications).

What is Computer?

• A computer transforms data into meaningful information.
• It processes input data according to instructions given by the user to produce output.
• Function: accepts, stores, processes, retrieves stored data, and prints the result.
• Computer stands for: Common Operating Machine, Purposely Used for Technological Educational Research

Input and Output Devices

• Input devices allow users to enter data into the computer (e.g., mouse, keyboard, joystick, microphone).
• Output devices display or give results after processing the input (e.g., printers, monitors, speakers).

Computer Devices

• Input Devices: Keyboard, Mouse, Scanner, Joystick, OMR, OCR
• Output Devices: Monitor, Printer, Speaker

Central Processing Unit (CPU)

• The CPU is the "brain" of the computer.
• It handles all data processing operations.
• It stores data, intermediate results, and instructions (programs).
• It controls the operations of all computer parts.

Memory Unit

• Stores data and instructions for processing.
• Stores intermediate and final processing results before releasing them to output devices.
• All inputs and outputs pass through the main memory.

Control Unit

• Manages the transfer of data and instructions among computer units.
• Coordinates all computer units.
• Obtains and interprets instructions from memory.
• Directs computer operations and communication with input/output devices for data transfer.
• Does not process or store data.

ALU (Arithmetic Logic Unit)

• Subsection of the CPU.
• Consists of an Arithmetic Section and a Logic Section.
• Memory types: Primary (main) memory and Secondary memory

Primary Memory (Main Memory)

• Semiconductor memory.
• Often called main memory.
• Volatile memory (data lost when power is off).
• The computer's working memory.
• Faster than secondary memory.
• Examples: RAM and ROM

Secondary Memory

• Magnetic and optical memories.
• Backup memory.
• Non-volatile memory (data persists when power is off).
• Used for data storage in computers.
• Slower than primary memory.
• Examples: disk, CD-ROM, DVD

Characteristics of Computer Systems

• Speed: Executes calculations faster and more accurately than humans. Measured in GigaHertz and MegaHertz. Enables fast processing of millions of instructions per second.
• Automation: Automates tasks after instructions (programmed); replacing human workers in many jobs; achieved using scripts, programs, and batch processing.
• Versatility: Performs different tasks with the same speed and accuracy; examples: music listening, PowerPoint, Wordpad, website design.
• Diligence: Works continuously for extended periods; makes millions of calculations per second, without fatigue or errors.
• Reliability: Consistent and accurate results for similar input data sets; output depends entirely on input.
• Accuracy: Performs computations and operations with low error rates; inaccuracies are often caused by incorrect data input by humans.

Introduction to MS Office

• MS Office is a collection of applications.
• Designed for Microsoft productivity.
• Used to complete tasks in various industries (documents, emails, spreadsheets).

Commonly Used MS Office Applications

• Microsoft Word: Word processing application for creating and formatting text documents.
• Microsoft Excel: Spreadsheet application for managing and analyzing data.
• Microsoft PowerPoint: Presentation application for slideshow creation.
• Microsoft Outlook: Email and personal information manager.
• Microsoft Access: Database application.

MS Office 2013 Applications

• Excel, OneNote, Outlook, Word, PowerPoint, Access, Publisher, Lync

MS Word

• Used to create professional documents (letters, reports, etc.).
• Features advanced formatting tools.
• Editing and formatting options.
• Steps for opening MS Word on a computer

Uses of MS Word

• Used in education (creating notes, assignments).
• Used in workplaces (creating letters, bills, reports).
• Used in creating resumes.
• Used by authors for writing and editing books

MS Word Features

• Home: Font formatting, alignment, bullets, line spacing.
• Insert: Tables, shapes, images, charts, graphics, headers, footers, page numbers.
• Design: Templates and layouts to enhance document appearance.
• Page Layout: Margins, orientation, columns, lines, indentation.
• References: Citation, footnotes, table of contents, bibliography, useful for lengthy documents.

MS Word Editing

• Cut: Removes text from one place and stores it in the clipboard for pasting somewhere else (using Ctrl+X).
• Copy: Duplicates and stores text in the clipboard (using Ctrl+C).
• Paste: Inserts text that was copied or cut into the new location (using Ctrl+V).

MS Word Undo/Redo

• Undo: Reverses previous action (using Ctrl+Z).
• Redo: Repeats previous action that was reversed (using Ctrl+Y).

MS Word Find

• The Find pane helps to locate characters, words, and phrases within the document.
• Searching for terms and data.

MS Word Replace

• Replaces found words or phrases with new ones in the document.
• Replacing terms and data.

Formatting

• The way the text appears (font size, style, color, spacing between paragraphs, alignment).
• There are selection shortcuts to highlight sections of texts.

Printing

• Opening the print preview pane for checking the document before printing.
• Selecting the appropriate printer and print settings.

Chart and Mail Merge: Charts

• Inserting charts
• Replacing default chart data with user data
• Closing the spreadsheet

Mail Merge

• Creating emails or messages for multiple recipients.
• Preparing the main message document.
• Connecting the message document with recipient data.
• Previewing and finishing the mail merge process

Working with Hindi Fonts

• Kruti Dev (legacy) vs. Unicode (universal standard)
• Kruti Dev limitation (limited character set).
• Unicode support (wide range of characters)

Interchange between two and getting acquainted while using Hindi for/Mobile Applications

• Setting the Hindi font on iOS devices (Settings > Display > Font Size)
• Setting the Hindi font on Android devices (Settings > Display > Font Size)

Using Hindi font in mobile applications

• Choosing a Hindi font.
• Ensuring application support for Unicode.
• Testing the Hindi text rendering.
• Localizing the app.
• Enabling accessibility features for users with visual impairments.
