in the designing and implementation of satellite-ATM networks. First a reference satellite-ATM network architecture is presented along with an overview of the service categories available in ATM networks. The error characteristics of satellite channels‚ and techniques to improve the error characteristics‚ and the impact on ATM network performance are then discussed. A delay model for satellite networks and the major components of delay and delay variation are described. A survey of design options

Thus the Talking Energymeter/Smart energymeter would be the an interactive representative of the company for the purpose of taking readings without involving human error. 1.1 BACKGROUND 1.1.1 DESCRIPTION OF ELECTRIC METER An electric meter or energy meter is a device that measures the amount of electrical energy consumed by a residence‚ business organisation‚ or an institution. Electric meters are typically

probability of loss or error. Unacknowledged networks provide simpler and faster communication for networks that are inherently reliable or provide service to higher layers that can tolerate information loss. 2. Explain the difference between connection-oriented acknowledged service and connectionless acknowledged service. How do the protocols that provide these services differ? Solution: The use of acknowledgments can provide reliable transfer over networks that are prone to error and loss. In connection

Convolution codes and viterbi algorithm Name Rahul Kumar Department of Electronics & Communication Engineering Lovely Professional University‚ Kapurthala‚ Punjab. Abstract:- A convolutional code is a type of error-correcting code in which each m-bit information symbol (each m-bit string) to be encoded is transformed into an n-bit symbol‚ where m/n is the code rate (n ≥ m) and the transformation is a function of the last k information symbols‚ where k is the constraint length of the code.

is used for controlling the flow of data when congestion has actually occurred. Error control It is the process of detecting and correcting both the bit level and packet level errors. The network is responsible for transmission of data from one device to another device. The end to end transfer of data from a transmitting application to a receiving application involves many steps‚ each subject to error. With the error control process‚ we can be confident that the transmitted and received data are

transfers per second and multiplying by 8 c. 1333MHz this is the frequency the memory operates at 7) Explain the differences between ECC memory and non-ECC memory. ECC memory stands for error correcting code. The data path width for DIMMs is normally 64 bits with ECC the data path it 72 bits the extra 8 bits are for error checking. For ECC to work the motherboard and all installed modules must support it. 8) What feature is used on memory slots and modules to prevent modules from being inserted incorrectly
