Networking Concepts
Network Types: LAN (Local Area Network), WAN (Wide Area Network), MAN (Metropolitan Area Network), and PAN (Personal Area Network).
Protocols and Types: Key networking protocols like HTTP, HTTPS, FTP, SMTP, DNS, and DHCP.
Network Ports: Common ports like Port 80 (HTTP), Port 443 (HTTPS), Port 21 (FTP), etc.
SOHO Network: Small Office/Home Office networks that connect devices via routers and modems.
Network Hardware
Understanding the hardware that powers networks is essential. Here’s a breakdown:
Router: Connects local networks to the internet and assigns IP addresses.
Switch: Connects multiple devices in a LAN and helps manage traffic.
Hub: Basic network device that sends data to all devices.
Bridge: Used to connect different network segments.
Access Point: Allows wireless devices to connect to a network.
Data Synchronization
Data Synchronization ensures data is consistent across multiple devices. It’s essential for cloud computing and file-sharing systems.
Virtualization & Cloud Computing
SaaS, PaaS, IaaS: The different types of cloud services:
SaaS (Software as a Service) like Google Docs
PaaS (Platform as a Service) for developers like Heroku
IaaS (Infrastructure as a Service) like AWS, which offers virtual machines and storage
Operating System Basics
Command Line Tools: Essential for troubleshooting and administrative tasks.
Operating System Types & Features: Differences between Windows, macOS, and Linux, and their key features.
Control Panel & Settings: How to navigate and customize system settings.
System Utilities: Tools to optimize, clean, and manage your computer (e.g., Disk Cleanup, Task Manager).
Networking in OS: How operating systems manage networking, IP configuration, and DNS.
Security Settings: Adjusting firewall settings and other security measures.
Security Essentials
Types of Threats:
Malware: Viruses, Trojans, Ransomware, and Spyware.
Phishing: Tricks used by cybercriminals to steal sensitive information.
User Authentication:
Two-Factor Authentication (2FA) for additional security.
Biometrics: Using fingerprints, facial recognition, or other biometric methods for secure login.
Securing Devices & Networks:
Firewall: Crucial for protecting a network from unauthorized access.
Software Troubleshooting
OS Errors: Fixing common operating system errors such as Blue Screen of Death (BSOD), slow performance, and startup issues.
Application Issues: Solving app crashes, missing DLL files, or compatibility problems.
