Segmentation of data happens at transport layer. Because transport layer is responsible for successful transportation of data through out the network.
The Transport layer (layer 4) handles segmentation and reassembly of the data.
Middle layer of osi model is Transport layer functions: 1.Segmentation of data 2.connection managment 3.flow control of data 4.Error checking
The transport layer segments data whenever the size of the packet is too large to transport efficiently--in practice, this happens whenever the data is too large to fit in a single network layer packet. Although the network layer can also fragment packets, the process is inefficient and generally the transport layer segment size is adjusted so that no further division is required in the network layer. Much more details are here: http://en.wikipedia.org/wiki/TCP_header#Maximum_segment_size
Which of the OSI layers handle the following. 1.dividing the transmitted bit stream into frames? Data link layer Which of the OSI layers handle the following: 2.dividing the application data into segments? Transport layer the PDU (Packet Data unit) for layers is as the following - Application, Presentation, and Session layers ==> uses Data - Transport layer ==> uses Segment - Network layer ==> uses Packets - Data link layer ==> uses Frames - Physical layer ==> uses Bits. ....
In the OSI model, encapsulation occurs as data is passed down through the layers. At the Application layer (Layer 7), data is created and then passed to the Presentation layer (Layer 6) for formatting. The Session layer (Layer 5) manages sessions, while the Transport layer (Layer 4) adds headers for segmentation and reliability. As data moves down to the Network layer (Layer 3), it receives IP addressing, followed by the Data Link layer (Layer 2), which adds MAC addressing and framing, and finally, the Physical layer (Layer 1) transmits the raw bits over the physical medium. Each layer adds its own header (and sometimes footer) to the data, forming a protocol data unit (PDU) specific to that layer.
A transport layer is the backbone of TCP/IP and the Internet. In this day and age, there are not design flaws in the system. The design of transport layer incorporates data stream with transmission.
Geographic segmentation is analyzing and collecting information according to the physical location and other data sources
Application layer: Data Presentation layer: Data Session layer: Data Transport layer: Segment (TCP) or Datagram (UDP) Network layer: Packet Data Link layer: Frame Physical layer: Bit
Most company use data analysis application or crm software
Layer 2 (Data Link Layer) http://compnetworking.about.com/cs/internetworking/g/bldef_bridge.htm
the network layer --> check your question. ^^^^^^^^^^^^^^^^^^^^^^^^^^^ That is totally not the right answer, how about you actually read the book for the course. It is the data link layer that does encapsulation. I agree - its the Data Link Layer which encapsulates the Network layer...NOT the Network Layer.
The segmentation function maintains a segment table that includes physical addresses of the segment, size, and other data. Segmentation speeds up a computer's information retrieval by assigning related data into a “segment table” between the CPU and the physical memory.
