Lossless Compression of Sound


Lossless audio formats use compression to keep file sizes down to a reasonable level. Lossless formats use compression algorithm that reserve audio data so the audio is exactly same as the original source. Audio files are made up of sound and silences. Lossless formats are able to compress the silences to almost zero space while maintaining all the sound data.

Examples of popular lossless formats used for storing music include:
FLAC, WAV, ALAC, WMA, etc.

Advantages:
Ripping two lossless audio files gives you an exact bit-for-bit copy of the original music CD. Convert it to any format and achieve the highest quality that format can support.

Disadvantages:
Compared to the formats like MP3, lossless formats are not well supported on hardware devices such as smartphones and tablets. Lossless audio files typically require more storage space than lossily encoded once.

Note:
Lossless compression is used in the zip file format. Some image file format like PNG or GIF, use only lossless compression, while other like TIFF and MNG main use either lossless or lossy methods.

Advantages of EDI

1) Shortened Ordering Time : Paper orders have to be printed, enveloped and sent out by the customer's post room, passed through the postal service, received by the supplier's post room and input to the supplier's order pocessing system. To achieve all this, reliably, in under three days would be to do very well. EDI orders are sent straight into the network and the only delay is how often the supplier retrieves messages from the system. Orders can be in the supplier's system within a day, or if there is urgency, the messages can be retrieved more frequently, for example every hour.  2) Cost Cutting : The use of EDI can cut costs. These include the costs of stationery and postage but these will probably be fully matched by the costs of running the EDI service. The principle saving from the use of the EDI is the potential to save staff costs. For example, if the orders are directly input to the system there is no need for an order entry clerk.  3) Elimination of Errors :...

Infrastructure for EC

Introduction The e-commerce infrastructure is defined here as the supporting capabilities for online trading between multiple companies which include hardware, software, networks, online payment technologies, security and encryption technologies, online trading business models, legal and regulatory framework, and managerial and organisation capabilities.  Infrastructure is the shared human, informational , and technical resources on which the work system relies in order to operate, even though these resources exist and are managed outside of the work system.  To evaluate the interdisciplinary aspects of construction e-commerce infrastructure, one proposes using a four pillar approach. Figure 5.1 illustrates the skeleton for the proposed integrated construction e-commerce infrastructure. The proposed integrated e-business infrastructure can be broken down into the following four groups of components:  1) Technological Infrastructure : Technology infrastructure is a work...
