What does HDLC mean?
High-level Data Link Control (HDLC) High-level Data Link Control (HDLC) is a group of communication protocols of the data link layer for transmitting data between network points or nodes. Since it is a data link protocol, data is organized into frames.
What is HDLC (high-level data link control)?
High-level Data Link Control (HDLC) is a group of communication protocols of the data link layer for transmitting data between network points or nodes. Since it is a data link protocol, data is organized into frames.
What is an HDLC frame?
Some HDLC variants extend the address field to include both source and destination addresses, or an explicit command/response bit. Three fundamental types of HDLC frames may be distinguished: Information frames, or I-frames, transport user data from the network layer. They can also include flow and error control information piggybacked on data.
What is the HDLC protocol?
It is a bit – oriented protocol that is applicable for both point – to – point and multipoint communications. HDLC supports two types of transfer modes, normal response mode and asynchronous balanced mode.
What is HDLC NRM?
HDLC is an ISO standard developed from the Synchronous Data Link Control (SDLC) standard proposed by IBM in the 1970’s. HDLC NRM (also known as SDLC) . HDLC is a bit oriented protocol that supports both half-duplex and full-duplex communication over point to point & multipoint link.
What is the normal range for HDLC?
Most HDLC blood test results will fall between 40-50 mg/dL for men and 50-59 mg/dL for women. This has been associated with an average overall risk of heart disease when taken as an individual test result. If the HDLC blood test results are above 60 mg/dL, this this is associated with a below average risk of heart disease.
What does a high HDLC blood test result mean?
Having a high level of HDLC is not necessarily a bad test result, though HDL and LDL levels are often compared to one another to develop a cholesterol ratio to determine the total risk a patient may face. When Will the HDLC Blood Test Be Ordered? The HDLC blood test may be ordered as part of a complete lipid profile during an annual health checkup.
