Which of the following is the primary communications protocols for the Internet?

The interconnection of systems and computer networks is the foundation of communications today and is designed using multiple communication protocols. For example, there are many protocols when establishing an internet connection and depending on the type that needs to be established, these protocols will vary. Furthermore, communication with the Internet is not the only type of communication when we refer to data transmission and exchange of messages across networks. In all cases, network protocols define the characteristics of the connection.

A protocol is a set of rules: the network protocols are formal standards and policies, made up of restrictions, procedures, and formats, that define the exchange of data packets to achieve communication between two servers or more devices over a network.

Network protocols include mechanisms for device identification and the establishment of connections between them, as well as formatting rules that specify how packets and data are structured in messages that are sent and received. Some protocols support message recognition and data compression, designed for reliable, high-performance network communication.

Types of Network Protocols

The most important protocols for data transmission across the Internet are TCP (Transmission Control Protocol) and IP (Internet Protocol). Using these jointly (TCP/IP), we can link devices that access the network; some other communication protocols associated with the Internet are POP, SMTP and HTTP.

We use these practically every day, although most users don't know it, and don't understand how they work. These protocols allow the transfer of data from our devices so that we can browse websites, send emails, listen to music online, etc.

There are several types of network protocols:

  • Network communication protocols: Basic packet communication protocols such as TCP/IP and HTTP.
  • Network security protocols: they implement security in network communications between servers; includes HTTPS, SSL, and SFTP.
  • Network management protocols: these provide network maintenance and governance, they include SNMP and ICMP.

A group of network protocols that work together at the top and bottom levels are commonly referred to as a protocol family.

The OSI model (Open System Interconnection) conceptually organizes network protocol families into specific network layers. This Open System Interconnection aims to establish a context to base the communication architectures between different systems.

Below we list some of the best known network protocols, according to the layers of the OSI model:

Layer 1 Protocols - Physical Layer

  • USB: Universal Serial Bus

Which of the following is the core communications protocol for the Internet?

Definition: TCP/IP (Transmission Control Protocol/Internet Protocol), also referred to as the Internet Protocol Suite, is the World Wide Web's core communication system that enables every Internet-connected device to communicate with every other such device simultaneously.

On which of the following protocols is the Internet based?

TCP/IP stands for Transmission Control Protocol/Internet Protocol and is a suite of communication protocols used to interconnect network devices on the internet. TCP/IP is also used as a communications protocol in a private computer network (an intranet or extranet).

What is a primary reason for the use of open protocols on the Internet?

Which of the following is a primary reason for the use of open protocols on the Internet? A Open protocols allow devices to specify how data packets are to be routed on the Internet in advance.

What is the Internet protocol IP )? Quizlet?

The Internet Protocol (IP) is the principalcommunications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables internetworking, and essentially establishes the Internet.
