tEleCommunICATioN and MUltiMedia: TRansmIssioN Media

2 weeks berehat2.. :P

berehat laa sgtt an an .. :D

so kembali ke kelas ! 

minggu ni kami belajar tentang cable...

before uh...

bia ak gtaw yg transmission media ni terbahagi kepada DUA kategori...

bounded and unbounded media

bounded media

provide a conduit from one to another

dalam bounded media ni plak..

ada guided media yg terbahagi kepada TIGA kategori

twisted - pair cable

coaxial cable

fibre - optic cable

twisted pair

terdapat DUA forms

unshielded (UTP) and shielded (STP)

UTP ~ terdapat LIMA kategori

senang maw ingat..ingat keyword die je..

C1- voice

C2 - local talk (apple product)

C3 - intranet (most of scholl used)

C4 - token ring

C5 - fast internet

STP ~ 

coaxial cable

(coax) carries signal of higher frequency ranges than twisted pair cable

Coaxial cable standard

di kategorikan daripada radio governement (RG).

RG-8. used in  Thick Ethernet

RG-9. used in Thick Ethernet

RG-11. used in Thick Ethernet

RG-58. Used in Thick Ethernet

RG-75. Used for TV

optical fibre

kalau maw taw... yg ni lebih bagus daripada UTP ngan STP

diperbuat daripada glass or plastic

unbounded media

wireless. transport electromagnetic waves without using a physical conductor

e.g radio frequency allocation

terdapat dua signal dalam cable which is CURRENT dan LIGHT

twisted pair cable + coaxial cable = current

optical fibre + wireless = light

so ni je laa tok minggu ni dulu ea...

minggu yang sgtt BZ dan memenatkan..

sweety 20s,

sugaramour.
