Computer and Communication Networks
FEKT-MPC-PKSAcad. year: 2020/2021
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.

Lectures are focused on presenting structure, architecture, and operational principles of computer and communication networks to students, and on training practical approaches to their design and configuration.
Specification of controlled education, way of implementation and compensation for absences
Evaluation of activities is specified by a regulation, which is issued by the lecturer responsible for the course annually.
