transfer speed of information is very vital in the operation. If their information is fast‚ more work can be done and more objectives will be met. However‚ if data transmission is slow‚ less tasks can be accomplished and more time will be wasted. In a company with different branches‚ distance will be a problem for data transmission. Without any direct connections‚ it will be very difficult to share information between branches. Filinvest Land‚ Inc. (FLI)‚ a subsidiary of Filinvest Development

Theory Introduction- In this report I will be writing about Signal Theory and all of its aspects‚ this involves talking about how data is transferred over a network‚ what a packet is and what information it contains‚ asynchronous and synchronous transmission‚ errors that data may encounter and what protocols are in place to avoid this from happening. Digital Signalling Methods- When data is sent over a network‚ it can either be through a wired or a wireless technology. The data is sent over a

contains the engine‚ transmission‚ and driveshaft. The name Boss 302 was given by Ford because they used a 302 ci engine in the Mustang. The engine placed in the Boss 302 was given a little bit extra. Ford gave the engine a four valve carburetor to help the engine produce 290 horsepower and 290 foot pounds of torque. The transmission is another key component in the drivetrain. The transmission’s main purpose is to shift the gears and keep the engine’s RPMs low. The car’s transmission is powered by

DCN VIVA QUESTIONS 1. What do you mean by data communication? Ans: It is the exchange of data between two devices via some form of transmission medium such as wire cable. The communicating system must be part of a communication system made up of a combination of hardware and software. The effectiveness of a data communication system depends on three fundamental characteristics: delivery‚ accuracy and timeliness. 2. What is simplex? Ans: It is the mode of communication between two devices in which

and regulations that govern how data is to be transmitted across a network. It defines the regulations regarding software as well as hardware. To enable two/more devices to communicate‚ they must follow the same protocol - an agreed format for transmission of data between devices. The protocol determines things such as: Type of error checking to be used‚ data compression methods‚ etc. Packet A network packet is the fundamental component of transmitting data over a network. All data being transferred

ABSTRACT Gi-Fi will helps to push wireless communications to faster drive. For many years cables ruled the world. Optical fibers played a dominant role for its higher bit rates and faster transmission. But the installation of cables caused a greater difficulty and thus led to wireless access. The foremost of this is Bluetooth which can cover 9-10mts. Wi-Fi followed it having coverage area of 91mts. No doubt‚ introduction of Wi-Fi wireless networks has proved a revolutionary solution to “last
