How many protocols are there in the network?
To get started, this glossary explores 12 common network protocols all network engineers should be familiar with. This includes the protocols' main functions, as well as why these common network protocols are important.
How does IP work?
IP functions similarly to a postal service. When users send and receive data from their device, the data gets spliced into packets, which are like letters with two IP addresses: one for the sender and one for the recipient. After the packet leaves the sender, it goes to a gateway, like a post office, that directs it in the proper direction. Packets continue to travel through gateways until they reach their destinations.
What is the purpose of TCP and IP?
Common network protocols, including Transmission Control Protocol (TCP) and Internet Protocol (IP), enable the exchange of information across the internet and work behind the scenes so effectively that many users don't think twice about them or how the internet works.

What is DNS in web?
DNS is a database that includes a website's domain name, which people use to access the website, and its corresponding IP addresses, which devices use to locate the website. DNS translates the domain name into IP addresses, and these translations are included within the DNS. Servers can cache DNS data, which is required to access the websites. DNS also includes the DNS protocol, which is within the IP suite and details the specifications DNS uses to translate and communicate.
Why is DNS important?
DNS is important because it can quickly provide users with information, as well as access to remote hosts and resources across the internet.
What is HTTPS in security?

How do routers work?
Routers allow packets to be transmitted to their destinations by monitoring the sea of networking devices interconnected with different network topologies. Routers are smart devices and store data on the networks to which they are connected. Most routers can be adjusted as a firewall for packet filters and can use ACLs.
What is hub in networking?
The hubs link various networking devices. A network also functions as amplification by amplifying signals that deteriorate over cables after long distances. In the network communication system family, a hub is the easiest, as it links LAN components with the same protocols. Digital or analog data can be used with a server as long as its configuration prepares for formatting the incoming data. Hubs do not process or address packets; they only send data packets to all connected devices. We send data packets. Hubs operate on the Open Systems Interconnection (OSI) physical layer. Two types of hubs exist: simple and multiple.#N#There are two types of Hubs:
What is gateway in router?

How do digital signals work?
Digital signals are transmitted through analog phone lines using modems (modulator demodulators). The modem converts digital signals into analog signals of various frequencies and transmits them to a modem at the receiver location. The receiving modem turns the other way and provides a digital output to a device, normally a computer, connected to a modem. In most cases, digital data is transmitted via the RS-232 standard interface to or from a serial line modem. Most cable operators use modems as final terminals to locate and remember their homes and personal clients, and many phone companies provide DSL services. All physical and data link layers are operating on modems.
What is a modem phone?
Let’s look more closely at some of these phones. The modem is a system that can send and receive data through phone or cable lines from a computer. The data stored on the device is digital, while a phone line or cable wire can transmit only analog data.
What is the purpose of the Internet protocol?
The Internet Protocol is the principal protocol in the Internet protocol suite for relaying data across networks. Its routing function essentially establishes the internet. Historically it was the connectionless datagram service in the original Transmission Control Program; the other being the connection oriented protocol (TCP). Therefore, the Internet protocol suite is referred as TCP/IP.
What is a network protocol?
Simply, a protocol is a set of rules. A network protocol is a set of rules followed by the network. Network protocols are formal standards and policies made up of rules, procedures and formats that defines communication between two or more devices over a network. Network protocols conducts the action, policies, and affairs of the end-to-end process of timely, secured and managed data or network communication. They define rules and conventions for communication. They incorporate all the processes requirement and constraints of initiating and accomplishing communication between computers, routers, servers and other network enabled devices. Network protocols must be confirmed and installed by the sender and receiver to ensure networkdata communication. It also applies software and hardware nodes that communicate on a network. There are several types of network protocols.
What is the Internet protocol suite?
Internet protocol suite is the set of communication protocols that implement the protocol stack on which the internet runs. The Internet protocol suite is sometimes called the TCP/IP protocol suite, after TCPIP, which refers to the important protocols in it, the Transmission Control Protocol (TCP) and the Internet Protocol (IP).
