What are the advantages and disadvantages of data compression?
hahaaha
Which layer manages data-format information for networked communications?
presentation layer
Which layer of osi model has the important role of providing error checking?
Data link Layer
Explain the difference between a PDU and a datagram?
A PDU (Protocol Data Unit) is defined by which layer it is in. In the physical layer and network layer, it is synonymous with the packet, in the data link layer, it is the frame. In the transport layer, it is a datagram for UDP. A datagram holds one or more PDU's, as it is the basic unit of transferring information via packet switching.
What are the 7 layer of network?
It's called the OSI Model... it has 7 layers. 1) Physical Layer 2) Data Link Layer 3) Network Layer 4) Transport Layer 5) Session Layer 6) Presentation Layer 7) Application Layer
Data compression mechanism in computer network?
presentation layer
What layer of the OSI model performs error correction?
Layer 2 - The Data Link Layer Layer 2 of the OSI model provides error-detection capability
At which OSI layer does data compression take places?
A network consists of multiple computers communicating with one another over a shared network medium. Topology refers to the shape of a network, or the network's layout. In this unit, you have learnt about the various topologies and its structure. The OSI model is a seven-layer model for communications and computer network protocol design. In this unit, you have learnt about the OSI model and the functions of the various layers.
According to the OSI model which layer performs parity checking and error checking?
Data Link layer does the parity error checking Thanks, Samaresh
What are the three primary functions of the presentation layer?
Coding and conversion of Application layer data to ensure that data from the source device can be interpreted by the appropriate application on the destination device. Compression of the data in a manner that can be decompressed by the destination device. Encryption of the data for transmission and the decryption of data upon receipt by the destination.
What layer of the OSI model ensures that the information sent at the application layer of one system is readable by the application layer of another system?
The Presentation layer must make certain that the format of the data will be understandable by the Application layer. This includes the use of encryption, compression, different graphics formats, etc. It uses a technique known as Portable Data Representation that allows data from different hardware to be able to communicate.
What layer of the OSI model performs routing?
network layer
What is compressing loss?
Data Compression is a technique to minimize the space used by data in storing. So when we do compression of data, no data is loss.
What has the author James C Tilton written?
James C. Tilton has written: 'Space and Earth Science Data Compression Workshop' -- subject(s): Data compression, Image processing '1993 Space and Earth Science Data Compression Workshop' -- subject(s): Data compression '1995 Science Information Management and Data Compression Workshop' -- subject(s): Information management, Data compression
What are the principles of data compression?
There are some basic principles of data compression. They include advantages, disadvantages, and the history of compression. Types of compression include BZip2 and LZMA.
What compression technique does data de duplication use?
Data de duplication is a process that eliminates duplicate copies of repeating data. The compression technique that it uses to function is called intelligent data compression.
How does DATA compression impact the quality of data?
It shouldn't. DATA Compression just mininalizes the space it's taking up
