IPDP - installation and operating instructions

1.2 Used terminology

 Ethernet is a family of frame-based computer networking technologies for local area

networks (LANs)

 LAN - a local area network (LAN) is a computer network covering a small physical

area, like a home, office, or small groups of buildings, such as a school, or an airport

 10Base-T – 10 Mbit/s, it uses 8 position modular connectors, usually called RJ45 in

the context of Ethernet over twisted pair. The cables usually used are four-pair

twisted pair cable (though 10BASE-T and 100BASE-TX only actually require two of

the pairs). Each of the standards support both full-duplex and half-duplex

communication. According to the standards, they all operate over distances of up to

100 meters

 100Base-TX – so called Fast Ethernet, two pairs of UTP or STP cable, category 5

 Twisted pair cabling is a type of wiring in which two conductors (the forward and

return conductors of a single circuit) are twisted together for the purposes of

canceling out electromagnetic interference (EMI) from external sources; for instance,

electromagnetic radiation from unshielded twisted pair (UTP) cables, and crosstalk

between neighboring pairs

 UTP, Unshielded Twisted Pair

 STP, Shielded Twisted Pair – the cabling includes metal shielding over each

individual pair of copper wires. This type of shielding protects cable from external

EMI (electromagnetic interferences)

 WEB - World Wide Web (WWW, or web) – a world-wide application of HTTP

internet protocol

 HTTP (Hypertext Transfer Protocol) is an internet protocol used originally for

exchanging hypertext documents in HTML format

 USB (Universal Serial Bus) – modern way of connecting external devices to the

computer

 Video codek („coder and decoder“) - compression H.263 is derived from MPEG-4,

H.264 is a coder for MPEG-4 AVC format. MPEG-4 is a type of video compression –

decreasing of data stream video sequence

 JPEG is a standard method of loss compression used for saving digital images

 Voice over Internet Protocol (VoIP) is a technology enabling transmission of

digitalized voice inside the packej of protocols family UDP/TCP/IP via komputer

network. I tis used for making phone calls via Internet, Intranet or any other kind of

data connection

 TCP/IP contains a set of protocols for communication in the computer network and it

is the main protocol of Internet

 IP address is a number, which clearly identifies a network interface in the computer

network, which uses IP protocol

 DHCP (Dynamic Host Configuration Protocol) is an application protocol from the

family of TCP/IP. It is used for automatic assigning of IP addresses to individual

personal computers in the PC networks, thus simplyfing their administration

 Internet is a word-wide system of mutually connected computer networks

 Intranet is a computer network similar to Internet, but it is a private one. That means

it is just used for small user groups (e.g. employees of a company)

 PoE (Power over Ethernet) is powering via data network cable, with no need of

bringing the power supply via a separate cable

 NTP (Network Time Protocol) is a protocol for synchronization of internal computer

clock
