CABLE ENCYCLOPEDIA

-

 TO BE CONTINUE 

There are different type of cable

1. coaxial cable.
2. Twisted pair cable. (T.P.)
3.shield twiestedpair cable.(S.T.P.)
4.UN shield twiested pair cable.(U.T.P.)

Coaxial cable- It consist solid copper that is surrounded by insulator it made by ( p.v.c.)
polly vinyle cloride. it have a different part.

Outer insulator- It is made by teflon.

Copper shield .- Some cable made by braid shield & some cable are foil shield & some is made by both style. It protect to the copper wire by R.F.I. & E.M.I. .

Insulation- It is upper to the copper wire. it made by teflon.

Copper wire- It is copper wire at a central of the cable. IEEE stands for coaxial cable.

R.G.58- It is approx (.64) centemeter in diameter . it,s use in environment in which all the device add or remove.it is also known as (10 base 2).Here 2 denotes the full length of the cable ( 200 meter).
it is also known as back bone  cable  (BNC- T) CONNECTOR is used to connect of the back bone cable.

R .G.-8- It is approx (.1) meter in diameter. 

10 base5- Here 5 denotes the 500 meter . N series connector use in 10 base 5 segement . 100 nodes attatch each 10 base 5 segement. 

R. G.-6 - it,s use in cable t.v. close circuit t.v.

R. G.-59- IT'S use in security camera home theater t.v. B.N.C.  connector use in this cable.

Twisted pair cable- pair of cable twisted arround to each other form . whenever pass through the wire a electromagnetic field generate arround the wire. it  is call loop. other wire come in loop so the signal pass on it them . so the signal of both wire get jumped to each other. it is called cross talk. avoid this problem wire is wounded.

U.T.P.- it is pair of copper wire that is wounded to each other. it is cheapest cable 
use for long networking only it define the different category.

10 base T- define the IEEE industry ELECTRICAL ELECTRONIC ENGINEERS. Here 10 is data transmission speed 10 m.b.p.s. . 
base is original signal before the modulation  & T is twisted pair cable.

CAT-1 - it is a tradional cable that carry voice data . it is used in telephoney .not in networking.

CAT-2 it carry 4 m.b.p.s. data. so it have a 4 pair cable.

CAT-3 - it carry data 10 m.b.p.s & freequency
16 M.H.Z.

Cat-4 - carry data 16 m.b.p.s. & freequency 20
m.h.z. 

cat-5 - 100 m.b.p.s. & freequency 100 m.h.z.
it's used in  100 base x architector & (a.t.m) 

cat-5-E- 1000 m.b.p.s. & freequency 100 m.h.z. .
Cat- 6 - it up grade to cat-5e trans mission speed 1000 m.b.p.s.  . & freequency 250 m.h.z. 

c.a.t. -7- it is totally shield pair cable freequency 600 m.h.z.

fiber optic cable.- in fiber optic cable the electrical signal converted in to light signal.
there are two type of fiber optic cable.
1. single mode
2. multi mode.

Today this post is finished . now new post will be continue so keep touch my blog
it will be continue.

                    Bios setup It is a plate form which is provide to make trigger of our system. all the hardware device attatch to our system we can enable& disable the work all these divice's & up ,&down the performance of these divice's when we go to in BIOS setup mostly we founde all these option, which is use to increase or decrease performance all attached hardware devices.so these option show in below manner. standard cmos setup- Enable the user to set basic information such as data time , IDE device disk drive. Advance setup- Sets advanced Information such as boot device  ' smart for harddisk boot up numlock, floppy drive swap about the system. power management system- Sets the parameters such as stand by time out , ring on power on for the system power management operation. PcI plug & play setup- Sets the parameters for the device installed on the pic bus & device which use the system plug & pl...

Topology

  Topology - It is different configuration to connect all devices of network. Network - It is group of devices to connect by communication path in which exchange the information and share resources. STRUCTURE OF NETWORK - There are two types of network point-to-point network multipoint networks. Point to point network - Point to point network in this type network there are two devices connected to each other data flow in this type network, local network to remote network, ex- satellite ,television ,microwave. Multi point - In this type network multi-device share of network it is also called multi drop connection. Structure of Topology - 1.physical topology 2. logical topology. Pysical topologies - In this Type Topology, it reffer To Connect All Device Physically.it means the physical shape of network. Logical Topologies - The Network Create Different Type But Actually Work's Logically.( it's shape is different). Type of Topologies - Single node, Star bus, Ring, Mesh,...

Printer

 The first electronic printer was the EP-101, invented by the Japanese company Epson and released in 1968.  so it was debuted in the market, The first commercial printers typically used mechanisms from electric typewriters and teletype machines. INTRODUCTION- The printer is an device that prints text document & image on paper. it is peripheral output device. IMPACT PRINTER- Printers are used for printing document  as well as graphics. the working of impact printer is very similer to that type of printer. lmpact printer are those printer, where physical contact is established between print head , cartridge&  media paper . the impact result in printing on paper under the ink ribbon. the dot matrix printer is an example of impact printer. DOT MATRIX PRINTER- Dot matrix printer uses a matrix of metal pins on the electromagnet printhead to creat dots & ink  soaked ribbon is placed between the paper & the print head . due to this dot matrix printer are...
