Introduction to Computers and Definitions
📌 A computer is defined as a multi-purpose, electronic, electrom-mechanical device that performs tasks for the user.
💻 Computers consist of two main parts: Hardware (physical, tangible components) and Software (coded instructions that run the hardware).
🔋 The term portable in computing refers to a device's ability to operate using a battery, enabling work on the go.

Types of Computers and Hardware/Software Roles
💾 Supercomputers are large, high-powered machines used by entities like NASA and universities for massive calculations.
⚙️ A Server is a powerful computer that provides essential network services such as printing, email, and file storage.
📱 Mobile Devices (like smartphones and tablets) are electronic and portable, often functioning as converging devices that combine multiple functions (camera, audio recorder, computing) into one unit.

The Information Processing Cycle and Data Concepts
🔄 The Information Processing Cycle involves four key stages: Input (data entry), Processing (data manipulation, using RAM/hardware), Output (displaying results), and Storage (permanent saving).
📊 Data is defined as raw, unprocessed facts (e.g., just a cell phone number), while Information is data that has been processed into a useful form.

Introduction to Windows and User Environment
🖥️ The booting process is when the operating system (like Windows, iOS, or Android) is automatically loaded upon switching the device on.
👤 A User Profile is a record of user-specific data that defines an individual's working environment on a shared computer.
🔑 Strong passwords should regularly change, contain a mix of uppercase/lowercase letters and numbers, and be between 6 and 30 characters long, avoiding consecutive repeated characters (e.g., 'oo').

Working within the Operating System and Saving Work
🖱️ Windows uses a Graphical User Interface (GUI), allowing users to interact via graphics using mouse actions like clicking, double-clicking, and dragging icons.
💾 Work done is temporarily held in memory; it must be saved to permanent storage (files/folders) to be retained.
🎯 When saving files, use meaningful names (e.g., not just "Geo") to facilitate future searching and retrieval.

Keyboard Fundamentals
⌨️ A QWERTY keyboard refers to the layout based on the first six letters on the top row of the keyboard.
🖐️ Proper touch-typing involves placing fingers on the home row keys: ASDF for the left hand and JKL; for the right hand, with thumbs on the space bar.

Key Points & Insights
➡️ A computer is fundamentally defined by its ability to process input into useful output based on coded instructions (software).
➡️ Understand the distinction: Booting up loads the OS; Logging on authenticates the user via credentials.
➡️ When saving work, transfer it from temporary memory to permanent storage and ensure files have descriptive, meaningful names.
