What is a protocol in a domain?

The Domain Name Protocol (DOMAIN) allows a host in a domain to act as a name server for other hosts within the domain. DOMAIN uses UDP or TCP as its underlying protocol and allows a local network to assign host names within its domain independently from other domains.

What protocol allows us to use a domain instead of an IP address?

DNS lets users connect to websites using domain names instead of IP addresses. Learn how DNS works.

What is a HTTP domain?

The domain name is a component of a uniform resource locator (URL) used to access web sites, for example: URL: http://www.example.net/index.html.

What are protocols?

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.

Does domain include protocol?

Domain Name (always present) Top Level Domain (TLD) (always present) Subdomain. Protocol (always present, not always visible)

Is HTTP a protocol?

HTTP is a protocol for fetching resources such as HTML documents. It is the foundation of any data exchange on the Web and it is a client-server protocol, which means requests are initiated by the recipient, usually the Web browser.

Is www still used?

In most cases, WWW serves no technical purpose. You can create a domain without its presence, and the website will still operate as any website should. So, why is WWW used so frequently? The use of WWW has been around since the creation of the internet, and its widespread use as a subdomain was largely accidental.

What is difference HTTP and DNS?

DNS server is to find out IP addresses of a domain name from DNS server. The request send by UDP protocol. And HTTP GET request is for getting web pages or contents from web server. This works on TCP protocol.

What are TCP protocols?

The Transmission Control Protocol (TCP) is a transport protocol that is used on top of IP to ensure reliable transmission of packets. TCP includes mechanisms to solve many of the problems that arise from packet-based messaging, such as lost packets, out of order packets, duplicate packets, and corrupted packets.

What are the three major network protocols?

There are three main types of network protocols, including network management protocols, network communication protocols and network security protocols.

What does UDP protocol do?

User Datagram Protocol (UDP) – a communications protocol that facilitates the exchange of messages between computing devices in a network. It’s an alternative to the transmission control protocol (TCP).

Which of the following protocols use TCP?

Detailed Solution. DHCP (Direct Host Configuration Protocol) and TFTP (Trivial File Transfer Protocol) employ a connectionless service model, using the User Datagram Protocol (UDP). While other given protocols (SMTP, HTTP, FTP) use TCP (Transmission Control Protocol) for connection-oriented transfer.

What is TCP and UDP protocol in networking?

TCP is a connection-oriented protocol, whereas UDP is a connectionless protocol. A key difference between TCP and UDP is speed, as TCP is comparatively slower than UDP. Overall, UDP is a much faster, simpler, and efficient protocol, however, retransmission of lost data packets is only possible with TCP.

What protocols use UDP?

UDP is a part of the Internet Protocol suite, referred to as UDP/IP suite.
…
Following implementations uses UDP as a transport layer protocol:
  • NTP (Network Time Protocol)
  • DNS (Domain Name Service)
  • BOOTP, DHCP.
  • NNP (Network News Protocol)
  • Quote of the day protocol.
  • TFTP, RTSP, RIP.

What is a Layer 4 protocol?

Layer 4 of the OSI model, also known as the transport layer, manages network traffic between hosts and end systems to ensure complete data transfers. Transport-layer protocols such as TCP, UDP, DCCP, and SCTP are used to control the volume of data, where it is sent, and at what rate.
