TCP/IP
The unabbreviated name of TCP and IP
What is Transmission Control Protocol, Internet Protocol.
This OSI layer is where web browsers and email clients operate, interacting directly with the user’s software.
What is the Application Layer
What protocol is responsible for the routing and addressing of devices and packets.
What is IP.
In data encapsulation, after adding the header, this piece of information is sometimes added at the end of the data to help detect errors during transmission.
What is a trailer?
Protocol for port 80
What is HTTP
This protocol is responsible for reliably delivering data between devices by establishing a connection and ensuring packets arrive in order.
What is TCP?
This OSI layer is responsible for moving data packets between devices on different networks and making routing decisions.
What is the Network Layer
This application-layer protocol uses port 53 and is responsible for translating human-readable domain names into IP addresses.
What is DNS
During data encapsulation, this term describes the additional information added to the front of data at each step, which helps guide the data to its destination.
What is a Header
Protocol for port number 23
What is Telnet
The TCP/IP model is used for what
What is data communication over the network
This OSI layer is responsible for converting data into electrical, optical, or radio signals, and defines the physical means of sending bits over a network.
What is Physical Layer
This protocol is responsible for the mapping of MAC addressed to IP addresses
What is ARP
At this TCP/IP layer, data segments are encapsulated by adding source and destination port numbers to enable multiple applications to communicate simultaneously.
What is Transport Layer
Protocol for port number 22
What is SSH
This field in the TCP header ensures that data is reassembled in the correct order by assigning a number to each byte transmitted.
What is Sequence Numbers
This layer of the OSI model is responsible for establishing, maintaining, and terminating connections between applications on different hosts.
What is Session Layer?
This protocol is the foundation of secure communication on the web, using encryption to protect data transmitted between browsers and servers.
What is HTTPS
During data encapsulation in the OSI model, this layer adds logical addressing information to a data packet before forwarding it to the Data Link layer.
What is Network Layer
Port number for RDP(Remote Desktop Protocol)
What is port 3389
What are the names of every packet header in the TCP/IP model, what layer do they belong to, and what do they do. (Hint: The header must include a protocol and the header type it is associated.)
What is TCP segment, IP packet, Ethernet Frame. TCP resides on the transport layer, IP resides on the internet layer, Ethernet resides on network access/network interface layer(either answer is acceptable). TCP is a reliable communication protocol that is used in most packet transfer operations except video, audio, and video games. IP is a routing and addressing protocol used so packets can reach their destination over the internet. Ethernet is protocol for wired connection typically used in LANs.
Name 7 protocols that reside in each layer of the OSI model independently.
What is Application: HTTP/FTP/DNS/SNMP/Telnet. Presentation: SSL/TLS. Session Layer: NetBIOS/PPTP. Transport Layer: TCP/UDP. Network Layer: IP/ARP/ICMP/IPSec. Data Link Layer: PPP, ATM, EthernetFrame. Physical Layer: Ethernet, USB, Bluetooth, IEEE802.11.
What does IGRP stand for
What is Interior Gateway Routing Protocol.
This field in the IP header helps routers determine how long a packet should exist in the network before being discarded.
What is the Time To Live (TTL)
protocol for port numbers 546 and 547
What is DHCPv6
