Which data link layer addressing scheme is used in a point-to-point logical topology?
Layer 2 addressing not required for this topology
What layer combines bits into bytes and bytes into frames and uses mac addressing?
Data Link
Which layer of the OSI model is primarily concerned with accessing the physical media and physical addressing?
Data Link
What is the role of the data link layer protocols in data transmission?
The role is to transfer frames to packets
What primary three functions does data link layer encapsulation provide?
* addressing * error detection * frame delimiting
Which layer ensures the trustworthy transmission of data across a physical link and is primarily concerned with physical addressing line discipline network topology error notification ordered deli?
The data link layer is responsible for ensuring the trustworthy transmission of data across a physical link. It handles physical addressing, line discipline, network topology, error notification, and ordered delivery of frames. By managing these functions, the data link layer ensures that data packets are reliably transmitted between directly connected devices.
What kind of address scheme is used at data link layer?
Data link layer transforms the physical layer and makes it appear error free. Data link layer is responsible for physical addressing. It has some other functions like error control, flow control and access control.
Which osi layer addresses data messages?
The OSI model has seven layers whereby each layer has its function. The Data Link Layer is responsible for addressing data messages so that they reach their destination correctly.
What is the purpose of addressing modes?
addressing modes helps the programmer to store or retrieve the data which is stored in any part of the data memory by addressing mode specified in the program.
How does 8085 access data from memory location?
Data can be accessed from memory by using the addressing modes, 8085 has 5 addressing modes namely,1. Immediate addressing mode 2. register addressing mode 3. direct addressing mode 4. indirect addressing mode 5. implied addressing mode
Describe the three different process addressing mechanisms?
1.Explicit Addressing 2.Implicit Addressing 3.Link Based Addressing
What are the adressing modes of 8085 microprocessor?
Different Addressing modes are: 1. Direct Addressing Mode 2. Indirect Addressing Mode 3. Immediate Addressing Mode 4. Register Addressing Mode 5. Implicit Addressing Mode Immediate addressing Data is present in the instruction. Load the immediate data to the destination provided. Example: MVI R,data Register addressing Data is provided through the registers. Example: MOV Rd, Rs Direct addressing Used to accept data from outside devices to store in the accumulator or send the data stored in the accumulator to the outside device. Accept the data from the port 00H and store them into the accumulator or Send the data from the accumulator to the port 01H. Example: IN 00H or OUT 01H Indirect Addressing This means that the Effective Address is calculated by the processor. And the contents of the address (and the one following) is used to form a second address. The second address is where the data is stored. Note that this requires several memory accesses; two accesses to retrieve the 16-bit address and a further access (or accesses) to retrieve the data which is to be loaded into the register.
