Computer and Communication Networks
FEKT-MPKSAcad. year: 2019/2020
Students become familiar with structure and architecture or networks; reference models; applications (HTTP, FTP, SMTP, DNS); the TCP/IP protocol suite (TCP, UDP, IP, routing, flow control, IP addressing, NAT); transmission media; local computer networks, access methods; Ethernet (principle, switches, VLAN, PoE, Spanning Tree), wireless network 802.11; broadband WAN technologies; multimedia applications (RTP, SIP, VoIP services, QoS); network security (basics of cryptography, authentication, integrity, certificates, SSL); and management (SNMP).
Learning outcomes of the course unit
The graduate is able to (1) understand basic theoretical principles of computer networks; (2) describe functions of individual components and protocols; (3) utilize network communication in designed instruments; (4) design and configure local networks.
Basic knowledge of mathematics (probability theory) and information theory (Shannon theorem, errors in the transmission, coding) is requested.

Planned learning activities and teaching methods
Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations. Techning methods include lectures, computer laboratories and practical laboratories. Course is taking advantage of e-learning (Moodle) system.
Assesment methods and criteria linked to learning outcomes
Computer exercises (25 points), laboratory exercises (15 points), final exam (60 points).
The exam will be online.

Lectures are focused on presenting structure, architecture, and operational principles of communication and computer 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.
