Introduction to Networking Technologies – The Practical Approach

• מבנה ומאפיינים של רשת תקשורת
• טכנולוגיות LAN  ו-WAN
• TCP/IP suite
• רכיבים ברשת תקשורת – switch & router
• חיבור לרשת האינטרנט
• מגמות עכשוויות ברשתות תקשורת

Networks Physical layers

• Typical network topologies: Bus, Ring, Star, Mash, FDDI
• Physical channels : STP/UTP, Coax, Optical fibers communication, wireless
• Physical devices, cables, connectors, repeaters hubs
• Standardization Institutes

Network Models

• OSI – relation model
• TCP/IP protocol
• Network hierarchical model
• Data Encapsulation
• Sniffing and analyzing data packets

Local Area Network

• Data-link layer
• Network Interface Card
• Frame processing
• Collision and broadcast domains
• Address resolution

Switching and Routing

• Switch and bridge
• Mac-address-Tables

Basic IP troubleshooting

• Sniffers and protocol analyzer
• Command line troubleshooting : ping, Netstat, Arp, Tracert etc

Application layer protocols overview:

• DHCP, DNS, HTTP, FTP, SNMP, SMTP, POP3
• Remote admin and others

Wide Area Network
