What is a computer?

A computer is an electronic device that manipulates information, or data. It has the ability to store, retrieve, and process data. You may already know that you can use a computer to type documents, send email, play games, and browse the Web. You can also use it to edit or create spreadsheets, presentations, and even videos.

What is an Operating system?

An operating system (OS) is system software that manages computer hardware and software resources and provides services for computer programs. It serves as an intermediary between users and the computer hardware, allowing for the execution of programs and efficient use of the system.

Key Functions of an Operating System:
Process Management: Manages the execution of programs, scheduling them for execution, multitasking, and ensuring that different applications do not interfere with each other.
Memory Management: Allocates memory to various applications and processes, ensuring that they have enough resources and that no two applications try to use the same memory space.
File System Management: Organizes data in a structured way using files and directories, and manages storage devices like hard drives or SSDs.
Device Management: Handles communication between the system and hardware devices (such as printers, keyboards, or network cards) through drivers.
Security and Access Control: Ensures the system is protected from unauthorized access and helps manage user accounts and permissions.
User Interface: Provides either a command-line interface (CLI) or graphical user interface (GUI) for users to interact with the computer system.

Types of Operating Systems:

Batch Operating Systems: Execute jobs in batches without user interaction.
Time-sharing Operating Systems: Allow multiple users to access the system simultaneously.
Distributed Operating Systems: Manage a group of independent computers and make them appear as one cohesive system.
Real-time Operating Systems (RTOS): Serve applications with strict timing constraints.
Examples of Operating Systems:
Windows
Linux
macOS
Android
iOS

Each operating system is designed for different types of devices and applications.

What is Cloud computing?

Cloud computing is the delivery of computing services over the internet (the cloud). It allows users to access resources such as storage, servers, databases, and applications without owning physical hardware. Examples include Google Drive and Amazon Web Services (AWS).

Cloud computing provides on-demand computing services over the internet, including servers, storage, databases, and software. It eliminates the need for owning physical hardware. Examples include platforms like Amazon Web Services (AWS), Microsoft Azure, and Google Cloud. It offers benefits like scalability, cost-effectiveness, and flexibility.

What is GUI?

GUI (Graphical User Interface) is a user-friendly interface that allows users to interact with electronic devices using graphical elements like icons, windows, and buttons instead of text-based commands. Examples include the interfaces of Windows and macOS.

Give 3 examples of input and 3 examples of output devices.

Input devices:

Keyboard
Mouse
Scanner

Output devices:

Monitor
Printer
Speakers

Explain different characteristics of computers.

Speed: Computers can perform millions of operations per second.
Accuracy: Computers produce error-free results if given correct instructions.
Storage: They can store vast amounts of data for future use.
Versatility: They can perform a wide variety of tasks.
Automation: Computers can perform tasks without human intervention.

Discuss essential characteristics of Cloud Computing.

On-demand self-service: Users can access computing resources as needed, without human intervention.
Broad network access: Resources are accessible over the internet from various devices.
Resource pooling: Cloud providers pool resources to serve multiple customers dynamically.
Rapid elasticity: Resources can be scaled up or down quickly based on demand.
Measured service: Cloud usage is tracked and billed based on consumption.

Explain different types of programming languages.

Low-level languages: Machine language and assembly language are closer to hardware and are harder to learn.
High-level languages: These are user-friendly and closer to human languages, e.g., Python, Java.
Scripting languages: Used to automate tasks, e.g., JavaScript, PHP.
Markup languages: Used for designing web pages, e.g., HTML, XML.

Describe 5 functions of an operating system.

Process management: Manages the execution of processes and multitasking.
Memory management: Allocates and deallocates memory as required by programs.
File system management: Controls the reading and writing of data on storage devices.
Device management: Manages input/output devices such as keyboards and printers.
Security management: Protects data by implementing access controls and preventing unauthorized access.

Discuss Compiler, Interpreter, and Assembler.

Compiler: Translates high-level code into machine code all at once. Example: C++ compiler.
Interpreter: Translates and executes code line by line, making it slower than a compiler. Example: Python interpreter.
Assembler: Converts assembly language into machine code that the CPU can execute.

Explain different types of memory.

Primary memory (RAM): Temporary memory that is fast but volatile, used by programs while they are running.
Secondary memory: Permanent storage like hard drives and SSDs, used for storing data long-term.
Cache memory: A small amount of high-speed memory located close to the CPU for quick access to frequently used data.
Virtual memory: A portion of the hard drive used to extend RAM when the system is low on memory.
ROM (Read-Only Memory): Non-volatile memory that holds critical startup instructions for the computer.

Classify different types of computers.

Supercomputers: Extremely powerful computers used for complex simulations and calculations. Example: IBM’s Summit.
Mainframe computers: Large systems used for bulk data processing in industries like banking. Example: IBM Z series.
Minicomputers: Mid-sized computers used in small businesses or as departmental servers. Example: PDP-11.
Microcomputers: Personal computers (PCs) or laptops used for everyday tasks. Example: Dell Inspiron.
Embedded computers: Computers integrated into other devices like microwaves or cars. Example: Raspberry Pi.

Differentiate between application software and system software with relevant examples.

Application software: Programs designed for end-users to perform specific tasks. Example: Microsoft Word for document editing.
System software: Software that manages hardware and provides a platform for running applications. Example: Operating systems like Windows or macOS.
