iV/ 3G: kizazi cha tatu/third generation. Katika cellular broadband yenye uwezo wa kusafirisha picha,sauti,data,video katika Chanell moja kwa mwendo wa kasi

V/ 2G: kizazi cha pili/ 2nd generation katika teknolojia ya cellular broadband chenye uwezo wa kusafirisha sauti, multimedia,text,

Vi/ 3D: pande tatu/three dimensions katika utengenezaji wa graphics. Umbile lenye kuonekana kwa realistic image and textures.

✔️DOMAIN NAME

♎Domain name, naweza sema ni k**a anuani (address) inayosaidia kifaa chako kuwasiliana na server.

♎Kwa kuwa mara nyingi ni ngumu kwa binadamu , kukumbuka namba, basi Domain name, imekuja k**a mbadala , ambapo yenyewe utumia njia ya maneno.

Kwa mfano: Url ya Facebook ni www.facebook.com lakini computer haifahamu lugha hii ya maneno, yenyewe inaelewa mfumo wa namba, hivyo basi www.facebook.com inaweza kubadilishwa na domain name server ambayo kazi yake ni ku tlanslate human readable address kwenda kwenye IP address. www.facebook.com== 192.168.10.2

♎Hivyo basi computer itaelewa kuwa 192.168.10.2 ni address ya Facebook lakini sisi tulitumia www.facebook.com ambayo ni domain name, lugha inayoeleweka na binadamu.

♎Kipindi kijacho nitakuja kueleza namna ya kusajili domain name na vitu vya kuzingatia wakati wa uchaguzi wa domain name.
