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

                           

worK in HEAdache....=(

i've got headache suddenly..so sorry 4 the simple post ok...not lazy to  make it more enjoyable but im feel like my head is turn around 4 a thousand time...haiiyyaaaaa~~ (@_@) so lets straight to the point k...

WiFi:
Fairly recently the IEEE 802.11 standard became more popular as it suites mobile computing devices really well. The IEEE 802.11 standard is another term for WiFi essentially is wireless networking. This standard allows two computers that have wireless NICs to communicate with one another with no strings (wires) attached. This standard makes use of radio waves that are transmitted through the air to communicate. Speeds of either 54 Mbps or 108 Mbps are supported but higher speeds are in the pipeline.

IEEE (Institute of Electrical and Electronics Engineers).
The IEEE describes itself as "the world's largest technical professional society; promoting the development and application of electro technology and allied sciences for the benefit of humanity, the advancement of the profession, and the well-being of our members." One of the technologies they have developed is known as Ethernet 802 standard which governs local area networks (wired LANs). Ethernet governs the way in which Data Communications are done across the spectrum.

Difference Between 3G And 4G
4G speeds are meant to exceed that of 3G. Current 3G speeds are topped out at 14Mbps downlink and 5.8Mbps uplink. To be able to qualify as a 4G technology, speeds of up to 100Mbps must be reached for a moving user and 1Gbps for a stationary user. So far, these speeds are only reachable with wired LANs.

different:
1. 3G stands for 3rd generation while 4G stands for 4th generation
2. 3G technologies are in widespread use while 4G compliant technologies are still in the horizon
3. 4G speeds are much faster compared to 3G
4. 3G is a mix of circuit and packet switching network while 4G is only a packet switching network

Cellular phone
is a device that can make and receive telephone calls over a radio link whilst moving around a wide geographic area. It does so by connecting to a cellular network provided by a mobile phone operator, allowing access to the public telephone network. By contrast, a cordless telephone is used only within the short range of a single, private base station.
In addition to telephony, modern mobile phones also support a wide variety of other services such as text messaging, MMS, email, Internet access, short-range wireless communications (infrared, Bluetooth), business applications, gaming and photography. Mobile phones that offer these and more general computing capabilities are referred to as smartphones. 

so simple right???hhmmmm...dun really like this kind of post but sorry i cannot help mith my worse condition...huhuhuhu...(T.T)

THE CONTINUE... XD

the title of this topics looks like a movie title..hahahaha..its early in the morning now..so GOOD MORNING!!!what a fresh morning....ermmm its a heavy rain outside my house and im keep on writing this and that just to ignore what had happen..so scarryyyy ok 2 see a heavy rain..huhuh..(-.-') But to make it more enjoyable i had listen one of my fave songs..just to feel sentimental in the morning..what the heckk!!! hahahahahaha...

just like to share this song..what a fresh morning...(^.^)V

so in this post, i think i want to write about RADIO FREQUENCY...did u know anything bout it??i have heard bout it before but not really sure about what is it exactly..it is a rate of oscillation in the range about 3kHz to 300GHz which corresponds to the frequency of radio wave and the alternating currents which carry radio signals... radio frequency usually refer to ascillation inside the circuit or electromagnetic rays... its a high freuency vacillating (AC) that move straight from aluminium conductor and then it will be radite on air by anthenna...how does it work??? ermmm..an anthenna change the signal cable to wireless signal and vice versa... when signal AC high frequency radiate on the air, it will form a radiowave. this radiowave will far from its source (anthenna) in one straight line.. to make it clear imagine u throw a stone in a calm pool..then it would form a ripple which the ripple come from one direction..the middle of the ripple is anthenna and the direction of the ripple form is the radiowave..now u can see it clear??hope so...huhuhuu..=)

 i think i want to stop here..then i will continue our topic soon..next topic is CELLUARPHONE....dont miss it ok!!! HAPPY SUNDAY EVERYBODY!! XD

unBOUnded MEdiA~~

hallo guys!!! it such a gud day of weekend right??HAPPY SATURDAY~~ XD Actually in this post i have much more thing to write about but hhhmmmmm we will see it..hehehehe...ok back to our topics about UNBOUNDED MEDIA.. do u know anything about it?? do u know the actual work this media work for?? im not really sure bout all of that before but by guided of my lect DR DAYANG, my eyes can see it clearly. she show me what had happen actually towards the data that we all send to our family, friend and teachers.its happen everyday in our life but we did not discover bout it..know lets learn bout it!! YEAHH!! XD (so happy in the early morning..(=.="))

UNBONDED MEDIA???? is a media which transport electromagnetic wave via air (vacumm) or water so enybody can receive it by a capable device.. got it???for example the ocean, atmosphere and space.. got it?? hope so...=) This media signal transmit in one direction through anthenna located at a high place such as tower and hills. the taller the anthenna, then longer the sight distance... There are 2 types of anthenna which is.....

HORN ANTHENNA...deflect outward in a series of narrow parallel beam...

PARABOLIC DISH... work like a funnel...

next is a SATELLITE... it has a same principle as terestrial microwave.. means transmit data through air..satellite has a high quality and same speed as earth.. let me show u how satellite looks a like..

this is one of the satellite at outer space..hhmmm..so fantastics..1 of human made that make me amaze all the time...=)

there so much more to write about and share but i think maybe next time...dunno why im feel uncomfortable about myself..so see u later bebehh!! XD

letS Play witH CablinGGGG..!!!!! XD

im back!!! my life little bit bz lately coz of......... of work la..hahha..but still ok 2 update this blog of knowledge..cewahhhh~~ ahhahha..back 2 the happy story.. in this post i like to share about cabling..u know bout it??if u know then gud...if u dun know..keep on read this ok!! gud person u are..hahahah..=P ok..no more play2...lets start our lesson...CABLE actually is a medium where an information pass through from one network device to another.. like a highway in our daily life la..cable consist of UNSHIELDED TWISTED PAIR (UTP), SHIELDED TWISTED PAIR (STP), COAXIAL CABLE, FIBRE OPTIC, AND WIRELESS LAN's...the signal for UTP, STP and Coaxial is a current while fibre optic and wireless is light such as infra red.. got it???hope u can understand....=)

let me explain little bit bout UTP and STP that has a twisted wire.. actually the purpose of a twist is to help eliminate interference from adjacent pairs and other electrical device.. if we do not use this twist then the distruption will be more then usual..heheheeh... standard connector for this cable is RJ-45 connector. can't imagine bout it???dun wory i have put a pics of it...=)

haaaa....!!! now u know this name is RJ-45 right??hahahaha...XD

STP is quiet same as UTP but 2 individual wires in in is wrapped with a foil sheilding to help provided more reliable data communication.. for ur information STP was more good then UTP bcause it suitable for environment with electrical interference.. means STP is lesser interference then UTP.. 

lets talk about COAXIAL CABLE...........

why when i see this i think about cigerette????don't u think it look same too??huhuhuhuhu..(=.=")

this cable has a single copper conductor at its centre..a plastic layer provide insulation between the centre conductor and the metal shield help to block any outside interference.. connector for this cable is BAYONE-NEILL-CONCELMAN (BNC) connector (can't this name be more longer???)  thats all bout coaxial cable..simple?? sometime simple thing is enough..heheeheheh..(^.^)V

turn for FIBRE OPTICS..!!!!!!!!!!!!!!

hehehehe..this cable is better then UTP and STP...wowww..!! how come it be like that???we will see.........

 its transmit light rather than electronic signals and eliminating the problem of electrical interference.. fibre optic suitable for environment that contain large amount of electrical interference.. its also able to transmit signals over much longer distances.. i also wonder how human can create this type of cable..so intelligent, creative and innovative.. incredible..!!! awesome..!!

don't u think its beautiful???? i think so...hehehe..=)

H.O.L.I.D.A.Y...!!!!!!!!!

its mid term break for dis semester..lots of things happen in my daily life..i went to PD enjoy my holy so much..1st time naek VIPER DRIFT..mak aiii such a cooooollllll thing...so fun, adventure and speechless...try it if u dare..hahahaaha..then meet my old fren..we talk, laugh and gossippingg of course..hahaha..neva mind but still a lot of work to do..be prepared 4 next mid sem..study n study n study..hahaha..=)

bla..bla..bla...

ape yg nk direpekkn kt sini sambil mkn kerepek ye???hahaha..x de mende pn...saje je nk merapu kat blog nih..da mcm rojak da blog aq nih...becampur-campur..klau aq blaja bahasa asing mmg dan dan la aq letak sume bahasa..baru la 1world..hahahaha...actually ni selingan je sebelom aq mula semula penulisan ilmiah aq tu..cewahh!! hehehee..ade gak la gaya prof aq ni kan...wakakakaka..!!pape pon korg enjoy la baca blog aq yg x seberapa nih..almaklum la x reti sangat bab bab IT nih..ok la...got to go...see u soon ok..daaaa..=)
