Computer and Communication Networks
FEKT-MPC-PKSAcad. year: 2021/2022
Students become familiar with structure and architecture or networks; theory of packet-switching networks; reference models; applications (HTTP, FTP, SMTP, DNS); the TCP/IP protocol suite (TCP, UDP, IP, routing, flow control, IP addressing); transmission media; local computer networks, media-access methods; Ethernet (principle, variants, switches, VLAN, PoE), wireless network 802.11; broadband WAN technologies; multimedia applications (RTP, SIP, VoIP services, QoS); network security (basics of cryptography, authentication, integrity, certificates, SSL); management and programming.
Learning outcomes of the course unit
The graduate is able to: (a) understand basic theoretical principles of computer networks; (b) describe functions of individual components and protocols; (c) utilize network communication in designed instruments; (d) design and configure local networks.
Basic knowledge of mathematics (probability theory) and information theory (Shannon theorem, errors in the transmission, coding) is requested.
