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. ....
What are the three primary functions provided by Layer 2 data encapsulation?
Primary functions provided by Layer 2 data encapsulation include data link layer addressing, and the detection of errors via cyclic redundancy check calculations. An additional function is delimiting groups of bits into frames.

What layer does a Wireless Acess Point utilize?
By layer, I am assuming you are talking about either the OSI 7 layer model or the TCP/IP 4 layer model. A router is fairly complex and provides services at 3 of the OSI model layers and 2 of the TCP/IP model layers. In the OSI model a router handles the Network Layer. In the TCP/IP model this layer is called the Internet Layer. It changes logical addresses to machine addresses and then finds paths (routes) to the destination node. It may break up the data into smaller parts for transmission or reassembling data received. There is no verification of successful transmission. A router also maintains a list of nodes that it is immediately connected to (computers, smart TV, Xbox, ...). Data segments from higher layers is converted to datagrams. Datagrams received from lower layers are translated into data segments. The router establishes a Data Link Layer to all devices it is immediately connected to . This layer provide reliable communication and can detect and sometimes correct errors at the Physical Layer. The datagrams received from the Network Layer are converted into data frames and sent to the Physical layer. Data frames received from the physical layer are converted into datagrams and sent to the Network Layer. The router also provides Physical Link Layer connections to all devices immediately connected to it. This is physical and electrical characteristics of the communication media (wire, fiber, wireless, ...). This is where the signals are negotiated like speed, timing, pin layout, voltages, ... After negotiation the physical layer is responsible for actual transmission of data over the line. Data frames received from the Data Link Layer are converted to bits and sent to the remote node. Bits received from the remote node are converted into data frames and sent to the Data Link Layer. The Data Link Layer and the Physical Layer are called the Link Layer in the TCP/IP model.
Does encoding occur at layer two of the osi reference model?
the physical layer (layer 1) manages hardware connections, handles sending and receiving binary signals, and handles encoding of bits.

What is the responsibility of physical layer?
The physical layer is the lowest layer of the OSI Network Model. It is the part that physically transfers data from one location to another location. For instance, in your cell phone, it is the physical radio that encodes, transmits, and decodes your data packets. In a carrier pigeon network, it would be the carrier pigeons and their pigeon roosts.

Consider a logical address space of eight pages of 1024words each mapped onto a physical memory of 32 frames how many bits are there in the logical address?
As was given for a 4 Page, 1024 words & 64 frames (shown below) 4 pages -> 2^2 bits 1024 bytes -> 2^10 bits 64 frames -> 2^6 bits Therefore: Logical memory = 2+10=12 bits Physical memory = 10 +6 =16 bits The answer for this problem is 13. 8 pages -> 2^3 bits 1024 bytes -> 2^10 bits 32 frames -> 2^5 bits Therefore: Logical memory = 3+10=13 bits (Page + Word) Physical memory = 10 + 5 =15 bits (Word + Frame)

What is the purpose of the tcp ip network access layer?
With regard to the TCP/IP Network Model, the network access Layer is the lowest logical layer in the model and provides specifications for how data (bits) should move over the network.
Consider a logical address space with 4 pages of 1024 bytes per pageeach mapped onto a physical memory of 64 frames. how many bits are there in logical address?
4 pages -> 2^2 bits 1024 bytes -> 2^10 bits 64 frames -> 2^6 bits Therefore: Logical memory = 2+10=12 bits Physical memory = 10 +6 =16 bits
