Society has become based solely on the ability to move large amounts of information across vast distances quickly. The natural evolution of computers and this need for ultra-fast communications has caused a global network of interconnected computers to develop. This global network allows a person to send E-mail across the world in mere fractions of a second‚ and enables even the common person to access information world-wide. With the new advancements in technology there must be a set of "rules"

The GTR not only packs a punch with the engine‚ but technology wise it contains viscous launch control‚ AWD‚ a dual matted clutch transmission with sequential paddle shifting and much more updated tuning. Launch control is a setting you can turn on that sets the GTR’s RPM’s perfectly to ensure the best possible take off. Sequential

operating at 433MHz. Our aim is to maximize the gain of the antenna and achieve impedance matching between load impedance and transmission line’s impedance. Among a wide range of different antennas‚ our group decide to build up a Yagi Uda antenna to fulfill this assignment for two main reasons. Firstly‚ the gain that Yagi Uda antenna provides is very high. Hence for transmission‚ Yagi Uda antenna makes sure all the transmitted wave to be directed to required area and for reception‚ it can receive maximum

of digital transmission? The advantage of digital transmission over analog transmission is noise immunity. Digital pulses are less susceptible than analog signals to variations caused by noise. Digital signals are better suited to processing and multiplexing than analog signals. Digital transmission systems are more noise resistant than the analog transmission systems. Digital systems are better suited to evaluate error performance. 2.What are the disadvantages of digital transmission? The transmission

Computer Networks NETWORKING CONCEPTS Network A network is basically an interconnection of various points to make a connected system e.g Road‚ Telephone‚ Social Data Network A computer network therefore refers to an interconnection of computers and other peripherals by use of a communication link Peer to Peer Networks In a peer-to-peer network‚ all computers are considered equal; they all have the same abilities to use the resources available on the network. Peer-to-peer networks are designed

I NTRODUCTION It has been known that use of multiple antennas at transmitter and receiver increases speed of data transmission between communication terminals. However‚ MIMO channel capacity is degraded by correlation and keyhole effects. Because of the keyhole effect [1]‚ [2]‚ the rank of MIMO channel matrix is reduced to one‚ even in the absence of antenna correlation
