* General concepts:
-- classification: WAN, LAN, PAN;
-- topologies;
-- reference models: ISO-OSI and TCP/IP;
-- circuit-switched and packet-switched networks;
-- connection-oriented services and acknowledged services;
-- flow control: stop-and-wait and sliding-window (go-back-N and Selective Repeat);
-- shaping and policing: leaky bucket and token bucket.
* The Physical Level:
-- transmission media and cable organization;
-- transmission type;
-- information representation (modulation);
-- multiplexing techniques (TDM, FDM, CDM) and multiple access (TDMA, FDMA, CDMA);
-- Fourier analysis and theorem of Nyquist and Shannon;
-- access networks (POTS, ISDN, ADSL, Fibre Channel, PON, Frame Relay, ATM, optical networks);
-- isochronous networks (PDH, SONET/SDH).
* The Data-Link Level:
-- aims and services;
-- framing;
-- examples: HDLC, SLIP and PPP.
* IEEE 802.X standards:
-- topologies and protocols: Ethernet, fast Ethernet, gigabit Ethernet, 10 gigabit Ethernet
-- the MAC sub-layer: Aloha, CSMA, CSMA/CD, CSMA/CA;
-- the LLC sub-layer;
-- bridge, switch and spanning-tree;
-- virtual LAN;
-- wireless LAN.
* The Network Level:
-- aims and services;
-- static routing and dynamic routing (distance vector, link state routing);
-- hierarchical routing;
-- the IP protocol:
---- packet format;
---- address format and use, netmask, ARP and RARP;
---- dynamic host configuration protocol (DHCP);
---- Internet control management protocol (ICMP);
---- interior-gateway protocols (RIP, IGRP, EIGRP, OSPF)
---- exterior-gateway protocols (BGP);
---- class-less inter-domain routing (CIDR);
---- IPv6;
-- layer-3 switch.
* The Transport Level:
-- aims and services;
-- TCP (3-way handshaking, flow control, retransmission, congestion control);
-- UDP;
-- secure socket layer (SSL);
-- firewall, NAT and PAT.
* The Application Level:
-- Domain Name Service (DNS),
-- the client/server model;
-- File Transfer Protocol (FTP);
-- electronic mail (SMTP, POP3 e IMAP);
-- World Wide Web (HTTP, HTTPS, CGI);
-- Simple Network Management Protocol (SNMP);
-- Secure Shell (SSH).
* Geographical networks:
-- classification and protocols;
-- virtual private networks.
