Darsni kuzatish va uning tahlili

Protokollar steki

Kompyuter tarmog`ini boshqarish davomida bir necha ko`rinishdagi protokollar to`plamidan foydalanish mumkin. Quyida ulardan bir nechtasi berib o`tilgan:

ARCNET, DECnet, Ethernet, IP, TCP, UDP, AppleTalk, Token Ring, IPX, SPX, FDDI, HIPPI, Myrinet, QsNet, ATM, IEEE-488, USB, IEEE 1394 (Firewire, iLink), X.25, Frame relay, Bluetooth, IEEE 802.11, Systems Network Architecture, RapidIO

Kommunikatsiya nazariyasi

1. Darajalar: 

    a) OSI modeli;

    b) Amaliy daraja;

    c) Axborotni taqdim etish darajasi;

    d) Seansli daraja;

    e) Transportli daraja;

    f) Tarmoqli daraja;

    g) Kommutatsiya;

    h) Marshrutizatsiya;

     i) Kanalli daraja (Ma`lumotlarning bog`lanish darajasi);

     j) Fizik daraja;

 

2. Tarmoqlar orasida ma’lumotlar almashish turlari:

a) Simli (o`tkazgichli) aloqa: PSTN telefon tarmog`i, Modem va kommutatorli aloqa, Belgili liniyalar(Выделенные линии);

b) Paketlar kommutitatsiyasi (Коммутация пакетов): Frame relay, PDH, Ethernet, RS-232;

c) Oprik tola bo`yicha ma`lumot almashinish: Synchronous optical networking, Fiber    distributed data interface;

d) Simsiz aloqa

i) Yaqin radiusli harakat: Bluetooth, Human Area Network;

ii) O`rta radiusli harakat: IEEE 802.11, Netsukuku

iii) Uzoq radiusli harakat: Sun`iy yo`ldoshli aloqa, MMDS, SMDS

e) Mobil telefon yordamida ma`lumotlar almashish: CSD, GPRS, HSCSD, EDGE, UMTS,      HSDPA, HSUPA, CDMA, CDPD, Paging networks, DataTAC, Mobitex, Motient;
