network protocol

Which of the following describes a system that maps domain names to various types of data, such as numerical IP addresses?

DNS - Domain name system

HTTPS

Hypertext Transfer Protocol Secure (HTTPS) is an extension of the Hypertext Transfer Protocol (HTTP). It is used for secure communication over a computer network, and is widely used on the Internet. uses TLS

VNC

In computing, Virtual Network Computing is a graphical desktop-sharing system that uses the Remote Frame Buffer protocol to remotely control another computer. It transmits the keyboard and mouse events from one computer to another, relaying the graphical-screen updates back in the other direction, over a network.

SNMP

It is a part of Transmission Control Protocol. Simple Network Management Protocol (SNMP) is a way for different devices on a network to share information with one another. It allows devices to communicate even if the devices are different hardware and run different software.

Which of the following is used when a WINS server tries to resolve a host name into an IP address on a Windows-based LAN?

NetBIOS

NETbios

NetBIOS is an acronym for Network Basic Input/Output System. It provides services related to the session layer of the OSI model allowing applications on separate computers to communicate over a local area network. As strictly an API, NetBIOS is not a networking protocol.

netBT

NetBIOS over TCP/IP is a networking protocol that allows legacy computer applications relying on the NetBIOS API to be used on modern TCP/IP networks

NAT

Network address translation is a method of remapping an IP address space into another by modifying network address information in the IP header of packets while they are in transit across a traffic routing device.

Transmission Control Protocol (TCP) is an example of a connectionless protocol. Because TCP doesn't support a three-way handshake while establishing a network connection, it is referred to as an unreliable or best-effort protocol. true ? false ?

false, UDP is the one that doesent use a "three way handshake" betweeen computers.

IMAP

the Internet Message Access Protocol (IMAP) is an Internet standard protocol used by email clients to retrieve email messages from a mail server over a TCP/IP connection.

POP3

the Post Office Protocol is an application-layer Internet standard protocol used by e-mail clients to retrieve e-mail from a mail server. POP version 3 is the version in common use.

SFTP

the SSH File Transfer Protocol is a network protocol that provides file access, file transfer, and file management over any reliable data stream. It was designed by the Internet Engineering Task Force as an extension of the Secure Shell protocol version 2.0 to provide secure file transfer

LAN

A local area network is a computer network that interconnects computers within a limited area such as a residence, school, laboratory, university campus or office building. By contrast, a wide area network not only covers a larger geographic distance, but also generally involves leased telecommunication circuits.

What is the function of FTP?

File exchange

FTP

File transfer protocol - The File Transfer Protocol (FTP) is a standard network protocol used for the transfer of computer files between a client and server on a computer network.

Which network protocol enables users to retrieve the contents of an Internet page from a web server?

HTTP

HTTP

HTTP means HyperText Transfer Protocol. HTTP is the underlying protocol used by the World Wide Web and this protocol defines how messages are formatted and transmitted, and what actions Web servers and browsers should take in response to various commands.

HTTPS vs HTTP

HTTP vs. ... HTTPS is HTTP with encryption. The only difference between the two protocols is that HTTPS uses TLS (SSL) to encrypt normal HTTP requests and responses. As a result, HTTPS is far more secure than HTTP. A website that uses HTTP has http:// in its URL, while a website that uses HTTPS has https://.

What is the name of a network protocol that secures web traffic via SSL/TLS encryption?

HTTPS - Hypertext Transfer Protocol Secure

TCP/IP

TCP/IP was developed by the U.S. Department of Defense to specify how computers transfer data from one device to another. TCP/IP puts a lot of emphasis on accuracy, and it has several steps to ensure that data is correctly transmitted between the two computers.

telnet

Telnet is a network protocol used to virtually access a computer and to provide a two-way, collaborative and text-based communication channel between two machines. tcp port/ 23

DNS

The Domain Name System (DNS) is the phonebook of the Internet. Humans access information online through domain names, like nytimes.com or espn.com. Web browsers interact through Internet Protocol (IP) addresses. DNS translates domain names to IP addresses so browsers can load Internet resources.

DHCP

The Dynamic Host Configuration Protocol (DHCP) is a network management protocol used on Internet Protocol networks whereby a DHCP server dynamically assigns an IP address and other network configuration parameters to each device on a network so they can communicate with other IP networks.

LDAP

The Lightweight Directory Access Protocol (LDAP /ˈɛldæp/) is an open, vendor-neutral, industry standard application protocol for accessing and maintaining distributed directory information services over an Internet Protocol (IP) network A common use of LDAP is to provide a central place to store usernames and passwords. This allows many different applications and services to connect to the LDAP server to validate users.

SSL/TLS

Transport Layer Security (TLS), and its now-deprecated predecessor, Secure Sockets Layer (SSL), are cryptographic protocols designed to provide communications security over a computer network

Which of the following is a file sharing network protocol? RDP SSH AFP SLP

AFP - apple filesharing protocol

AFP

Apple Filing Protocol, is a proprietary network protocol, and part of the Apple File Service (AFS), that offers file services for macOS and the classic Mac OS. In Mac OS 9 and earlier, AFP was the primary protocol for file services.

What is the function of POP3?

Email retrieval

FTPS

FTPS is an extension to the commonly used File Transfer Protocol that adds support for the Transport Layer Security and, formerly, the Secure Sockets Layer cryptographic protocols

Which of the following is a Microsoft-proprietary remote-access protocol providing users with a graphical interface that allows them to connect to another computer on a network?

RDP - remote desktop protocol

RDP

Remote Desktop Protocol is a proprietary protocol developed by Microsoft which provides a user with a graphical interface to connect to another computer over a network connection. you can control other desktops on the network from your own computer tcp 3389

IMAP is used for:

Retrieving email messages from a mail server

Which of the following protocols permits automated discovery of networked services on Local Area Networks (LANs)?

SLP - service location protocol

A type of cryptographic network protocol for secure data communication, remote command-line login, remote command execution, and other secure network services between two networked computers is known as:

SSH - secure shell

SSH

Secure Shell (SSH) is a transport layer that is used to secure logins and information moving between two endpoints.

SMB/CIF

Server Message Block (SMB). is a network communication protocol[3] for providing shared access to files, printers, and serial ports between nodes on a network. It also provides an authenticated inter-process communication mechanism.

SLP

The Service Location Protocol is a service discovery protocol that allows computers and other devices to find services in a local area network without prior configuration. SLP has been designed to scale from small, unmanaged networks to large enterprise networks.

SMTP

Short for Simple Mail Transfer Protocol, a protocol for sending e-mail messages between servers. Most e-mail systems that send mail over the Internet use SMTP to send messages from one server to another; the messages can then be retrieved with an e-mail client using either POP or IMAP.

TFTP

Trivial File Transfer Protocol (TFTP) is a simple lockstep File Transfer Protocol which allows a client to get a file from or put a file onto a remote host. One of its primary uses is in the early stages of nodes booting from a local area network. TFTP has been used for this application because it is very simple to implement.
