The development of communication from world war 2 till today?
Communication since WW2 has been enhanced by satellites, optical fibre cables, the Internet, WWW software and cheap computers.
What are commonly used communication channels?
Digital (discrete) or analog (continuous) channelBaseband and passband channelTransmission medium, for example a fibre channelMultiplexed channelComputer network virtual channelSimplex communication, duplex communication or half duplex communication channelReturn channelUplink or downlink (upstream or downstream channel)Broadcast channel, unicast channel or multicast channel
What is the fibre used to make rope?

What was invented by Narinder Kapany?
Narinder Kapany was born in Punjab, India and educated in England. He invented optical fibre and is called "Father of Fibre Optics".
What is full form of FRP?
Fibre-reinforced plastic
What are the advantages and disadvantages of lyocell?
Lyocell is supposed to be replacement for Viscose Rayon, which is considered as a non ecofriendly fibre because of manufacturing process which harmful top environment. Advantages of Lyocell are: 1) Lyocell manufacturing process is ecofriendly, NMMNO is used in manufacture of Lyocell fibre is recycled. 2)Dry and wet tenacity is very good in comparison to Viscose fibre. Disadvantages: 1) Fibrillation : which happens due to surface rupturing.
What are the diadvantages of cotton?

How do you use your wired broadband connection to connect your wireless laptop to the internet when there is no wireless network available?
You have two basic options. 1.You can connect your laptop to your cable, fibre optic, or DSL modem or Ethernet port using an Ethernet cord. 2. You can connect your cable, fibre optic, or DSL modem or Ethernet port to a wireless router using a Ethernet cable. You then connect your laptop using wireless to your wireless router.
What is bi-directional transmission?
A communication which occurs in both directions.When specific to fibre optics it refers to a single fibre which can handle synchronius and asynchronious communications.
A wireless network adapter enables connectivity between a desktop computer or laptop and what else wireless access point fiber optic PC card?
Fiber
What are the types of media used to link networks.?
Various types of media to link networking are copper, fibre, wireless.
What is needed for full-duplex Ethernet communication?
systems are running in fibre optic connection
What are the factors in choosing the right network media?
Cost - UTP cabling is cheap, whereas Fibre is expensive Ease of installation - Fibre requires specialist installation to run the cable and terminate the ends. UTP cables are much easier to handle. It may be impractical to run cables of any description leaving wireless as the only option. Security - data packets traveling over wireless can be intercepted very easily. UTP is more secure, but susceptible to EMI. Fibre is the most secure. Distance - long distances can be best handles by fibre Bandwidth - your expected usage requirements may exclude a particular medium.
Types of fiber optic sensors with defnitions and diagramatic representations?
Fibre optic cable comes under different types: Single-mode Multimode These two optical fibre cable is used for long-distance communication. Single-mode has carried a single source of data. Multimode is used for multiple data communication.
What are the advantages of using optical fiber instead of radio waves to carry signals?
see www.soe.ucsc.edu/classes/cmpe150/Fall05/lecture6.ppt for the answerAnswerThe biggest is less attenuation (degradation) of signal, so that a message can travel significantly further over an optical fibre than over a copper (twisted pair of coax) cable before it becomes too garbled to understand. In addition, fibre optic cables are generally immune to electromagnetic interference (such as strong electrical or magnetic fields) nearby, while copper cables can have such interference reduce or completely destroy their ability to carry signals. Finally, it is much easier to transmit on multiple channels (frequencies) over fibre than over copper, so a fibre optic cable can handle many more simultaneous message streams than twisted pair or coax. In short: fibre allows hugely greater distances between endpoints, is practically immune to outside interference, and can handle hundreds or thousands of times more signal channels than twisted pair or coaxial cable.
