1.IP = internet protocol (Tarmoqlar aro).
2.TCP = Transmission control protocol (yuborishlarni nazorat qilish).
3. TCP/IP = 2 ta kompyuterni bog’lash uchun birgalikda ishlatiladi.
4.IPv4 va IPv6 = biz IPv4 versiyasidan foydalanamiz.
5.IPv4 nima va qanday foydalanamiz.
xxx.xxx.xxx.xxx
0 xxx = 8 bit (jami 32 bit xisoblanadi). 11111111 = 10 lik sanoq sistemasida 255 ga teng.

1. 
   guruh 1-126 (birinchi xona soni). (254²)
   
2. 
   

B) guruh 128-191 (254²)
C) guruh 192-168
Маска подсети:
A)guruh 1-126 = 255.0.0.0 (254³)
B)guruh 128-191 = 255.255.0.0 (254²)
C)guruh 192-254 = 255.255.255.0 (0, 255 ni chiqarib tashlasak jami 254 ta kompyuterlarni bi biriga bog’lashimiz mumkin degani).
Lokal tarmoq IP lar
A)10.10.x.x B) 172.16-32.x.x C) 192.168.x.x
6) win + R -> ping kun.uz –t = kun.uz saytini nechinchi IP da ekanligini bilib olish mumkin.
7) 172.20.25.1 = (TATU shu IP dan foydalanmiz);
NECHTA WI-FI ULANGANLIGINI BILISH.
netsh
1.netsh wlan show = netsh buyrug`I bilan ishlaydigan komandalarni chiqarib beradi.
2.netsh wlan show drivers = sizning kompyuteringizdan tarqatish mumkinmi yoki yo’q bilib olamiz.
3. netsh wlan show profiles = nechta wi-fi ulanganligini chiqarib beradi.
4.netsh wlan set hostednetwork mode=allow ssid=ok key=12345678 = bunda wi-fi tarqaydi.
5.netsh wlan start hostednetwork = ishlashi uchun shu komandani yozamiz.
6.netsh wlan export profile folder=C:\ key=clear = c diskga xamma wi-fi larni malumotini tashlab beradi.
7.netsh wlan show profile Life-Tech key=clear = shu wi-fi parolini ko’rsatib beradi.
8. netsh interface show interface = qaysi Wi-Fi aktivligini ko’rish.
9.ping 8.8.8.8 = aloqa borligini tekshirish.
10. netsh interface set interface "Беспроводная сеть" disabled = ulangan Wi-Fini o’chirish.
11. netsh interface set interface "Беспроводная сеть" enabled = ulangan Wi-Fini yoqish.
