Sending data

This paper aims to investigate factors affecting the application of management accounting in Vietnamese enterprises. Quantitative research was conducted and data was collected by sending questionnaires to 120 companies in the manufacturing, trading and service sectors in Vietnam.

A WLAN is a shared network. An access point is a shared device and functions like a shared Ethernet hub. Data is transmitted over radio waves. Two-way radio communications (half-duplex) are used. The same radio frequency is used for sending and receiving (transceiver).

In random access or contention methods, no station is superior to another station and none is assigned the control over another. No station permits, or does not permit, another station to send. At each instance, a station that has data to send uses a procedure defined by the protocol to make a decision on whether or not to send.

Data transmission can contain errors. – Single-bit. – Burst errors of length n. (n: distance between the first and last errors in data block) • How to detect errors. – If only data is transmitted, errors cannot be detected. Send more information with data that satisfies a special relationship. -Add redundancy

Describe the basic purpose of a router – Computers that specialize in sending packets over the data network – They are responsible for interconnecting networks by selecting the best path for a packet to travel and forwarding packets to their destination Routers are the network center – Routers generally have 2 connections: • WAN connection (Connection to ISP) • LAN connection

This diagram illustrates the Physical layer (Layer 1) of the OSI model. The Physical layer is responsible for the ultimate transmission of data over network communications media. It operates with data in the form of bits that are sent from the Physical layer of the sending (source) device and received at the Physical layer of the destination device. Ethernet cabling, Token Ring network technology and SCSI all function at the Physical layer of the OSI model. Hubs and other repeaters are standard network devices that function at the Physical layer.

BRINGING FORMS TO LIFE The ability to reuse the same script—perhaps with only a few edits—for multiple websites is a great timesaver. However, sending the input data to a separate file for processing makes it difficult to alert users to errors without losing their input. To get around this problem, the approach taken in this chapter is to use what s known as a self-processing form. Instead of sending the data to a separate file, the page containing the form is reloaded, and the processing script is wrapped in a PHP conditional statement above the DOCTYPE declaration that checks if the...

THE TELEPHONE NETWORK The early history of the telephone system has been outlined in Chapter 1. The growth of the telephone system has been truly phenomenal and forecasts show a continuing growth as new services such as data transfer, facsimile and mobile telephone are added. The telephone differs from the broadcasting system in two basic ways: (1) In broadcasting, a few people who, in theory, have information send it out to the many who are presumed to want the information; it is one-way traffic....

This application note introduces the concepts of digital modulation used in many communications systems today. Emphasis is placed on explaining the tradeoffs that are made to optimize efficiencies in system design. Most communications systems fall into one of three categories: bandwidth efficient, power efficient, or cost efficient. Bandwidth efficiency describes the ability of a modulation scheme to accommodate data within a limited bandwidth. Power efficiency describes the ability of the system to reliably send information at the lowest practical power level.

Synchronous Mode Synchronous systems negotiate the connection at the data-link level before communication begins Basic synchronous systems will begins. synchronize two clocks before transmission. Asynchronous mode Asynchronous systems do not send separate information to indicate the encoding or clocking information. The receiver must decide the clocking of the signal on it's own. This means that the receiver must decide where to look in the signal stream to find ones and zeroes.
