What is a network protocol?
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 are the three major network protocols?
Generally speaking, networks have three types of protocols — communication, such as Ethernet; management, such as the Simple Mail Transfer Protocol (SMTP); and security, such as Secure Shell (SSH).
What is network protocol with example?
Examples of standard network protocols are TCP (Transmission Control Protocol), UDP (User Datagram Protocol), IP (Internet Protocol), ARP (Address Resolution Protocol), HTTP (Hypertext Transfer Protocol), FTP (File Transfer Protocol), TFTP (Trivial File Transfer Protocol), SMTP (Simple Mail Transfer Protocol), SSH ( …
What are types of protocols?
Types of Protocols
- Transmission Control Protocol (TCP)
- Internet Protocol (IP)
- User Datagram Protocol (UDP)
- Post office Protocol (POP)
- Simple mail transport Protocol (SMTP)
- File Transfer Protocol (FTP)
- Hyper Text Transfer Protocol (HTTP)
- Hyper Text Transfer Protocol Secure (HTTPS)
What is protocol example?
A protocol is a standard set of rules that allow electronic devices to communicate with each other. Protocols exist for several different applications. Examples include wired networking (e.g., Ethernet), wireless networking (e.g., 802.11ac), and Internet communication (e.g., IP)….
What is a written protocol?
A protocol is simply a recipe, or written design, for performing the experiment. A scientist usually writes his/her protocol in a laboratory notebook. Following the completion of the protocol, the next step in the scientific process is to perform the experiment.
How do protocols work?
Each network protocol defines rules for how its data packets must be organized. Because protocols like Internet Protocol often work together in layers, some data embedded inside a packet formatted for one protocol can be in the format of some other related protocol (a method called encapsulation)….
Which protocol is used in Web?
Hypertext Transfer Protocol (HTTP)
Which protocol is used to encrypt?
SSL/TLS protocol
What is the function of HTTP protocol?
HTTP is a protocol which allows the fetching of 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….
What is TCP IP with example?
The transport layer software (TCP) would take the HTTP packet, add a TCP segment, and then hand it to the network layer software (IP). The network layer software will compare the destination address (128.192. 98.53) to the subnet mask (255.255. 255.0) and discover that this computer is on its own subnet.
What is TCP IP in simple words?
TCP/IP stands for Transmission Control Protocol/Internet Protocol. TCP/IP is a set of standardized rules that allow computers to communicate on a network such as the internet….
What is TCP IP means?
Transmission Control Protocol
What is the purpose of IP protocol?
The Internet Protocol is responsible for addressing host interfaces, encapsulating data into datagrams (including fragmentation and reassembly) and routing datagrams from a source host interface to a destination host interface across one or more IP networks.
What OSI layer is TCP?
Transport Layer
How do I know if I have TCP or UDP?
Run netstat -an from a Windows command prompt. Download and run TCPView (which also lists UDP) for a GUI view. Run Wireshark. Run nmap against the server with port in question (by default only scans TCP ports)…
What is port 110 used for?
Port 110 is used by the POP3 protocol for unencrypted access to electronic mail. The port is intended for end-users to connect to a mail server to retrieve messages. I can’t imagine any reason that this port would be used in this case. Port 25 is used by the SMTP protocol to send mail.
Is port 443 a TCP or UDP?

Which protocol is port 443 use for?
http protocol over TLS/SSL
Can I use port 443 for HTTP?
Though Port 443 is the standard port for HTTPS traffic, HTTPS port 443 can also support HTTP sites….
