IP ADDRESS- wuxu ka kooban yahay 32 bit oo binary ah, waxane lo qeybiyaa 4 sideedaad, waane 4 byte, 8 walba waxa u dhaxeeya dhibic ama dot. Tusaale :- 192.168.1.1 waa cinwaan gaar ah oo tilmaamaya aalad ku jirta internetka ama shabakad maxalli ah. Waxa macquul ah in marka la jooga Private-ka kompuytarada qaar isku IP noqdaan, IP wuxuu u taagan yahay “Internet Protocol,” kaas oo ah xeerar lagu maamulo qaabka xogta loo soo diray internetka ama shabakadda qaaska ah. Nuxur ahaan, IP Address waa aqoonsi u oggolaanaya in macluumaadka loo diro inta u dhexeysa aaladaha shabakadda: waxay ka kooban yihiin macluumaadka goobta waxayna ka dhigaan aaladaha la heli karo isgaarsiinta. Internetku wuxuu u baahan yahay hab lagu kala saaro kombiyuutarada kala duwan, Routers-ka, iyo Server's-ka. Aaalad walba oo Network ama Internet ku xiran wuxu leeyahay IP Address la'aantiisne ma jirto device Isticmaali kara Internet ama Network. IP waxa loo qeybiyaa 5 class, Class walbane wuxu leeyahay meel u k...

♡● Network waa isku xirka laba device iyo ka badan meela isu dhawne yaalo, sida computers, servers, mainframes, network devices(Hub, Switch,  Router), peripherals, or device-yada kale. U jeedada la isugu xirayne eey tahay wadaagida xogaha iyo macluumaadka. Wuxu isku xiraa boqolaal ilaa kumanaan devices. Waxaa maamulaya ama controli kara shaqsiyaad.  Waxaa loo adeegsadaa Local Area Network, Wide Area Network, Campus Area Network, and Home Area Network. ♡● Internet waa mid aad u balaaran, waa isku xirka Network-ya badan, meela aad u kala fogne kala yaalo, waane Network of Networks, waxaane tusaale weyn u ah WAN. Wuxu isku xiraa Malaayiin devices. Ma jirto cid maamuli karto. Waxaa loo adeegsada World Wide Web. Mahadsanidiin.

Fiila Nooceeda Yahay UTP (Unshield Twist Pair), waxaa loo adeegsada isku xirka Network Devices. Si la isugu xiro waxa la raacaya heshiiska eey gaareen qolooyinka TIA/EIA kaaso kala saaraya qaabka la isugu xiraya fiilada iyo color-ka, Labada Nooc ee fiila waxeey qiima ku leeyihiin macnane ku sameeynayaan habka eey u xiranyihiin. Sida TIA/EIA 568A iyo TIA/EIA 568B. Straight through cable-  ayaa loo adeegsadaa shabakadaha LAN si loogu xiro aalado kala duwan sida  Hub to router, router iyo switch, PC and switch, iyo wixii la mid ah. Waxay beddel u tahay sidoo kale isku -xiriirinta wireless -ka ADSL-ka hal ama in ka badan oo kombiyuutarro ah ay ka helaan router -ka iyada oo loo marayo signal -ka wireless -ka. Crossover Cable- waxa loo adeegsada isku xirka LAN waa fiilo isgoys ah labada dhinac ku kala dhamaadaan (568A iyo 568B) oo loogu talagalay in si toos ah loogu xiro aaladaha Network-ga. Waxaa inta badan loo adeegsadaa in lagu xiro laba qalab oo isku nooc ah, tusaale. Computer t...

DDoS waa nooc ka mid ah weerarada xaasidnimo ee carqaladeeya taraafikada caadiga ah ee Network-ga si ay u galaan Server-ka, fatahaad ku sameysa taraafikada shabakada (taasoo dhalisa in la diido adeegga).  Waxay u shaqeysaa sida jid gooyo oo xayiraya wadada oo ka celineysa taraafikada caadiga ah inay yimaadaan halka ay ku socdaan. Aaladaha si fudud ugu xira shabakadda (sida kumbuyuutarrada, aaladaha IoT, taleefannada gacanta, iwm) waxay u nugul yihiin weerarada DDoS.
