Understanding the Role of Software in Computer Functionality

📚 Software, also known as programs or applications, contains instructions for the computer to perform tasks.

💻 User application software is installed by the user and allows them to perform tasks like sending messages or writing emails.

🔧 There are different types of software, including system software and utility software.

👩‍💻 User applications are programs that are written by programmers and can be installed on computers for users to use.

🖥️ Examples of user applications include games, office applications, web browsers, and file explorers.

💾 System software is responsible for helping the computer perform tasks, separate from user applications.

🔧 Software needs instructions to work on hardware.

💽 System software helps the computer access memory and save files.

💻 Application software allows users to play games, access spreadsheets, and browse the internet.

🖥️ System software is responsible for communicating with physical devices.

📟 Examples of system software include the boot program, BIOS, and device drivers.

💻 Operating systems are crucial system software that enable computer functionality.

🖥️ The operating system (OS) is a program that manages user applications and tells the hardware what to do.

💻 The OS handles memory allocation, multitasking, and provides a graphical user interface for interacting with the computer.

🔍 Common operating systems include Microsoft Windows, Apple Mac OS (OS X), Linux, and UNIX.

💻 There are four main operating systems: Microsoft Windows, Apple, and Linux.

🔧 Besides user applications and system software, there are also programs that users can write for specific tasks.

📝 Programs are sets of specific instructions written by programmers using a programming language.

💻 Computer software is written using programming languages like C, Java, or JavaScript.

📚 In this course, we will learn how to use a programming language to write our own software.

🌐 There are numerous programming languages, and new ones are being developed constantly.
