High-level Data Link Control (HDLC) and Synchronous Data Link Control (SDLC) are two different types of data link protocols. HDLC is a bit-oriented protocol, while SDLC is a character-oriented protocol. HDLC uses positive acknowledgement with retransmission for error control, while SDLC uses a cyclic redundancy check (CRC) for error detection.
What is HDLC ?
HDLC is a type of data link layer protocol that is commonly used in point-to-point and multipoint communications. It is a bit-oriented protocol, which means that it uses a bit stream to transmit information. HDLC is capable of error detection and correction, as well as flow control. HDLC is also used in conjunction with other protocols, such as the Point-to-Point Protocol (PPP), to provide a complete solution for data communication.
What is SDLC?
The SDLC, or software development life cycle, is a process that outlines the steps necessary to create software. It begins with the initial planning phase and ends with maintenance and support. In between these two phases are the requirements gathering, design, implementation, and testing phases. The SDLC is a iterative process, meaning that it can be repeated as many times as necessary in order to create a high-quality product.
The first step in the SDLC is the planning phase. During this phase, the goals and objectives of the software project are established. The budget and timeline are also set during this phase. Next is the requirements gathering phase. During this phase, the team collects information about what the user wants and needs from the software. This information is then used to create a functional specification document.
After requirements gathering comes the design phase.
Main differences between HDLC and SDLC
High-Level Data Link Control (HDLC) is a bit-oriented synchronous data link layer protocol developed by the International Organization for Standardization (ISO). HDLC is used to send data over point-to-point links and point-to-multipoint links.
The main difference between HDLC and SDLC is that HDLC uses asynchronous transmission while SDLC uses synchronous transmission. Synchronous transmission allows for a clock signal to be sent with the data, so that the receiver can reconstruct the data stream correctly. Asynchronous transmission does not send a clock signal, so the receiver has to use an agreed upon set of rules to determine when each byte of information starts and stops.

There are two types of filters for aquariums: HDLC and SDLC. HDLC is a high-pressure, low-volume filter that is used for small aquariums or those with delicate fish. SDLC is a low-pressure, high-volume filter that is best for large aquariums or those with tough fish. Both types of filters have their own advantages and disadvantages.
