Computer Hardware Basics

Hardware Components

• CPU (Central Processing Unit): Executes instructions and performs calculations
• Memory (RAM): Temporary storage for data and applications
• Storage (HDD/SSD): Permanent storage for data and programs
• Input/Output Devices: Keyboard, mouse, monitor, speakers, etc.
• Motherboard: Connects and supports all hardware components
• Power Supply: Converts AC power to DC power for the computer

Types of Computers

• Desktop Computers: Designed for stationary use, often more powerful and customizable
• Laptop Computers: Portable and designed for mobility
• Tablets: Touchscreen devices, often used for entertainment and basic tasks
• Servers: High-performance computers that manage and provide access to resources over a network
• Mainframes: Large, powerful computers used for high-volume data processing and storage

Software Components

• Operating System (OS): Manages hardware and provides a platform for running applications
• Applications: Programs that perform specific tasks, such as word processing or web browsing
• Firmware: Permanent software stored in read-only memory (ROM)

Computer Networks

• LAN (Local Area Network): Connects devices in a limited geographical area
• WAN (Wide Area Network): Connects devices over a larger geographical area
• Internet: A global network of interconnected computers and servers
• Network Protocols: Rules and standards that govern data transmission and communication, such as TCP/IP and HTTP

Computer Security

• Malware: Malicious software, including viruses, worms, and Trojan horses
• Firewalls: Software or hardware that blocks unauthorized access to a computer or network
• Encryption: Process of converting data into a secure, unreadable format
• Authentication: Verifying the identity of users or devices to ensure secure access
