What is a protocol in computer science?
A network protocol is an established set of rules that determine how data is transmitted between different devices in the same network. Essentially, it allows connected devices to communicate with each other, regardless of any differences in their internal processes, structure or design.
What is a protocol easy definition?
A protocol is a set of rules and guidelines for communicating data. Rules are defined for each step and process during communication between two or more computers.
What is a protocol computer science GCSE?
Protocols establish how two computers send and receive a message. Data packets travel between source and destination from one router to the next. The process of exchanging data packets is known as packet switching. Protocols manage key points about a message: speed of transmission.
What is network protocol with example?

Is a protocol a programming language?
Protocol is a term used by particular object-oriented programming languages with a variety of specific meanings, which other languages may term interface or trait. Protocol when used otherwise is akin to a communication protocol, indicating the chain of interactions between the caller and the object.
What is protocol example?
A protocol is a standard set of rules that allow electronic devices to communicate with each other. Examples include wired networking (e.g., Ethernet), wireless networking (e.g., 802.11ac), and Internet communication (e.g., IP).
What is a protocol in Java?

Why do networks need protocols?
Answer: Network protocols are needed because it include mechanisms for devices to identify and make connections with each other, as well as formatting rules that specify how data is packaged into messages sent and received.
Is Java a protocol?
Some programming languages provide explicit language support for protocols/interfaces (Ada, C#, D, Dart, Delphi, Go, Java, Logtalk, Object Pascal, Objective-C, PHP, Racket, Seed7, Swift). In C++ interfaces are known as abstract base classes, and are implemented using pure virtual functions.
Does Python use a protocol?
Protocols In Python While the concept is the same as Clojure, Python does not need explicit protocol declaration. If a type has the methods specified in the protocol, then it implements the protocol.
What is a computer ‘protocol’?
FTP (File Transfer Protocol). One of the many protocols used to upload or download files at high speeds over a computer network,and that privileges effectiveness over security.
What exactly does a computer scientist do?
Computer scientists use technology to solve problems. They write software to make computers do new things or accomplish tasks more efficiently. They create applications for mobile devices, develop websites, and program software . And you can find them everywhere, from big tech firms and government agencies to start-ups and nonprofits.
Is ISP a computer protocol?
When you are connected to the Internet through your service provider, communication between you and the ISP is established using a simple protocol: PPP (Point to Point Protocol), a protocol making it possible for two remote computers to communicate without having an IP address.
