Sure! Here are some study notes for CompTIA Network+:
1. Network Fundamentals:
- OSI and TCP/IP models
- Network topologies (e.g., bus, star, mesh)
- IP addressing (IPv4 and IPv6)
- Subnetting and supernetting
- DHCP (Dynamic Host Configuration Protocol)
- DNS (Domain Name System)
2. Network Infrastructure:
- Ethernet (standards, cables, connectors)
- Wireless networking (standards, encryption, channels)
- Network devices (routers, switches, hubs, firewalls)
- VLANs (Virtual Local Area Networks)
- WAN technologies (e.g., DSL, cable, satellite, cellular)
3. Network Operations:
- Network protocols (e.g., TCP, UDP, ICMP)
- Routing protocols (e.g., RIP, OSPF, BGP)
- NAT (Network Address Translation)
- VPN (Virtual Private Network)
- Network monitoring and optimization
- Troubleshooting network issues
4. Network Security:
- Network security devices (e.g., IDS/IPS, VPN concentrator)
- Access control (e.g., AAA, RADIUS, TACACS+)
- Firewalls and DMZ (Demilitarized Zone)
- Wireless security (e.g., WPA, WPA2, WPA3)
- Threat mitigation techniques (e.g., antivirus, antispyware)
5. Network Troubleshooting:
- Network troubleshooting methodology
- Common network issues (e.g., connectivity, performance)
- Hardware and software tools for troubleshooting
- Command-line tools (e.g., ping, traceroute, ipconfig)
- Remote access protocols (e.g., SSH, RDP)
6. Network Management:
- Network documentation and diagrams
- Configuration management
