A set of rules governing data exchange in networks

Protocol System[edit]

A protocol system is a comprehensive set of rules and conventions that dictate how data is transmitted and received across a network. These systems are essential for ensuring reliable and efficient communication between different devices and applications in a networked environment.

Overview[edit]

Protocol systems are fundamental to the operation of computer networks, including the Internet. They define the syntax, semantics, and synchronization of communication, as well as error recovery methods. Protocols can be implemented in hardware, software, or a combination of both.

Components of a Protocol System[edit]

A protocol system typically consists of several key components:

Syntax: This refers to the structure or format of the data, meaning the order in which data is presented. For example, the Hypertext Transfer Protocol (HTTP) specifies how messages are formatted and transmitted.

Semantics: This defines the meaning of each section of bits. It specifies the control information for coordination and error handling.

Timing: This includes the speed matching and sequencing of data. Timing ensures that data is sent and received at the correct speed and in the correct order.

Types of Protocols[edit]

Protocol systems can be categorized based on their function and the layer of the OSI model they operate in:

Application Layer Protocols: These include protocols like HTTP, FTP, and SMTP, which are used for specific applications.

Transport Layer Protocols: Protocols such as TCP and UDP manage the delivery of data between devices.

Network Layer Protocols: These include IP, which is responsible for addressing and routing packets of data.

Data Link Layer Protocols: Protocols like Ethernet and PPP manage the node-to-node data transfer.

Functionality[edit]

Protocol systems ensure that data is transmitted accurately and efficiently. They handle various tasks such as:

Error Detection and Correction: Protocols include mechanisms to detect and correct errors that occur during data transmission.

Flow Control: This prevents a fast sender from overwhelming a slow receiver by managing the rate of data transmission.

Congestion Control: Protocols help manage network congestion by controlling the amount of data entering the network.

Importance in Networking[edit]

Protocol systems are crucial for the interoperability of different network devices and applications. They enable devices from different manufacturers to communicate effectively, ensuring that data is exchanged in a standardized manner. Without protocol systems, the global connectivity provided by the Internet would not be possible.

-In a [[Health care|healthcare]] setting, a protocol, also called a [[medical guideline]], is a set of instructions which describe a process to be followed to investigate a particular set of [[Medical findings|findings]] in a [[patient]], or the method which should be followed to [[Disease Control|control]] a certain [[disease]].
+==Overview==
+Protocol systems are fundamental to the operation of [[computer networks]], including the [[Internet]]. They define the syntax, semantics, and synchronization of communication, as well as error recovery methods. Protocols can be implemented in hardware, software, or a combination of both.
-== Passive protocol systems ==
+==Components of a Protocol System==
-Passive protocol systems are a source of information which health care providers have the freedom to choose to consult or not; they are not intrinsically incorporated into the healthcare process. The purpose of a passive protocol system is to give healthcare providers access to information which may remind healthcare providers of steps during patient care which may otherwise be forgotten or changed.<ref name="auto"/>
+A protocol system typically consists of several key components:
-== Active protocol systems ==
+* '''Syntax''': This refers to the structure or format of the data, meaning the order in which data is presented. For example, the [[Hypertext Transfer Protocol]] (HTTP) specifies how messages are formatted and transmitted.
-Active protocol systems are specific guidelines for healthcare providers to follow. They are a central way which healthcare is delivered. Examples of active protocol systems include trigger-automated [[order entry]] systems and appointment scheduling. Active protocol systems may provide an explanation function which offers background information, definitions, [[risk]]s, and the rationale that supports specific recommendations.<ref name="auto"/>
