Data transfers

A USB system consists of a host computer, one or more USB devices, and a physical bus. The host consists of two layers: an upper software layer, which includes USB device drivers, and a host controller hardware layer, also known as an adapter layer. The main responsibility of the host computer is to control data transfers to and from USB devices. USB devices are peripherals that use the USB electrical and data format specifications to communicate with the host computer. The physical bus is the set of USB cables that links the controller with the peripherals....

This paper presents the design and implementation of DOT, a flexible architecture for data transfer. This architecture separates content negotiation from the data transfer itself. Applications determine what data they need to send and then use a new transfer service to send it. This transfer service acts as a common interface between applications and the lower-level network layers, facilitating innovation both above and below. The transfer service frees developers from re-inventing transfer mechanisms in each new application.

Chapter 23 - Process-to-process delivery: UDP, TCP, and SCTP. Chapter 23 discusses three transport layer protocols in the Internet: UDP, TCP, and SCTP. The first, User Datagram Protocol (UDP), is a connectionless, unreliable protocol that is used for its efficiency. The second, Transmission Control Protocol (TCP), is a connection-oriented, reliable protocol that is a good choice for data transfer. The third, Stream Control Transport Protocol (SCTP) is a new transport-layer protocol designed for multimedia applications.

Data compression presents Data in memory have used fixed length for representation, For data transfer (in particular), this method is inefficient; For speed and storage efficiencies, data symbols should use the minimum number of bits possible for representation.

Introduction Data link control layer – often abbreviated simply to data link layer – is concerned with the transfer of data over a serial data link The transmission mode may be either asynchronous or synchronous and based on either a character-oriented or a bit-oriented transmission control protocol The data link layer is fundamental to the operation of all data communication applications

In this paper, we present a new learning scenario, heterogeneous transfer learning, which improves learning performance when the data can be in different feature spaces and where no correspondence between data instances in these spaces is provided. In the past, we have classified Chinese text documents using English training data under the heterogeneous transfer learning framework. In this paper, we present image clustering as an example to illustrate how unsupervised learning can be improved by transferring knowledge from auxiliary heterogeneous data obtained from the social Web. ...

Creating labeled training data for relation extraction is expensive. In this paper, we study relation extraction in a special weakly-supervised setting when we have only a few seed instances of the target relation type we want to extract but we also have a large amount of labeled instances of other relation types. Observing that different relation types can share certain common structures, we propose to use a multi-task learning method coupled with human guidance to address this weakly-supervised relation extraction problem. ...
