INTERNET INFRSTRUCTURE..!! LAI LAI LAI..~~

okey..this week we learn about internet infrastructure..but before we proceed to them, i like to tell u all that the test is AWESOME!!! hehehe...(saje je nk bg gempakk) okey guys enough for the test..thats all..HAHA!!

the MOST IMPORTANT in internet infrastructure is:----> from single computer to LAN

                                                                                ----> LAN to ISP

                                                                                ----> ISP to WWW

haaa!! see this pics 1st and imagine it ok!! THE HIERACHY OF NETWORK~~ XD

what exactly INTERNET PROTOCOL??

actually it is a INTERNET STANDARD PROTOCOL... provides a common layer over dissimilar networks, used to move packets among host computers and through gateways if necessary. the IP address is unique and consist 32 bits=4 octets=0-225 of number either in binary form or decimal..feel dizzy???a lot of knowledge i like to share so hold on ur dizzyness..HAHA!!

this IP has 2 part which is for identifying network and the other one is to identify the node (all nodes share same network prefix but must have a unique host number). there are 4 classes of the address which is class A, B, C, D and E... take a look at the pic below::

hhmmm!! can u imagine how does it work?? (@_@)

ok2..i will explain little bit bout it ok... 

CLASS A NETWORK:::

-the binary address start with 0-
-decimal number is from 1to126-

1st 8 bits identify the network while the remains is to identify the host-

CLASS B NETWORK:::

-the binary address start with 10-

-the decimal number is from 128 to 191-

-127 is for loopback and internal testing-

-1st 16 bits identify the network while the remaining identify the host-

CLASS C NETWORK:::

-the binary address start with 110-

-the decimal number is from 192 to 223-

-1st 24 bits identify the network-

CLASS D NETWORK:::

-the binary address start with 1110-

-the decimal number is from 224 to 239-

-to support multicasting-

CLASS E NETWORK:::

-the binary address start with 1111-

-the decimal number is from 240 to 255-

-for experimentation-

er.... i think i like to stop here n continue with http and isp soon..hope u enjoy read my summary on dis chapter..

actually this week is a light chapter we learn and luckily we got dr Dayang as our lecturer...

in this chapter i see more clearly about the infrastructure that i never known before..

haiyaaaa~~got to go..

*this is the second post from me..i post the same before but dun know why it is not shown on my blog...

sorry for the disturbance dr...

hope u understand and not deduct my mark..!! heheheheh  XD
