Segmentation of data happens at transport layer. Because transport layer is responsible for successful transportation of data through out the network.
L4 The Transport Layer
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. ....
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
Tide's geographic segmentation tends to focus on urban and suburban areas with a high population density, as these regions tend to have more potential customers who are likely to purchase laundry detergent. They also target regions where the brand has established a strong presence and brand awareness through marketing efforts. Tide may also consider factors like climate and water hardness in different regions to tailor their product offerings.
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 โsegment tableโ between the CPU and the physical memory.
The term human segmentation is used for the technique of seperating individuals from a crowd in images, videos and related computer based applications. Human segmentation is a special branch of image segmentation. The goal is usually to provide data which is better and easier to analyze.
