CIS 260 TEST 2 QUESTIONS ANSWERED CORRECTLY LATEST UPDATE 2026
What do MacOS, Linux, and Windows all have in common - Answers They are all clients for p2p
networking
They are all clients for networking
What is the standard set of internet protocols used today - Answers TCP/IP
What is a connection-oriented protocol - Answers A protocol that requires an exchange of messages
before data transfer begins
This connection ensures all data makes it to its destination
TCP
What is a connectionless protocol - Answers No connection is made between the parties before data
transfer begins
There is no guarantee of packet delivery; packets may be lost
UDP
What is the purpose of connection-oriented protocols - Answers It is reliable, orderly, and error
correcting; this is at the expense of speed
What is the purpose of connectionless protocols - Answers Minimal setup, Used in real-time
communication (VOIP), efficient for unreliable networks
What are some examples of TCP protocols - Answers Telnet, SSH, FTP, HTTP (port 80), HTTPS, SSL,
RDP, SMTP
What are some examples of UDP protocols - Answers VoIP, DNS (actually uses both), DHCP, SNMP
What is tunneling? - Answers protocol is a communication method that encapsulates one network
protocol within another to ensure secure data transmission over a network.
-used for vpn
-used when encapsulating from IPv4 to IPv6
What is encapsulating packets - Answers packet encapsulation is a process used to transmit packets
over a network with various devices and protocols
You do this by wrapping a packet in the headers and info of a different protocol. When the packet
reaches its destination, it is unwrapped, and the original packet is read
What are logical ports - Answers Logical ports are virtual, not physical, communications gateways
that allow a computer to organize requests for information from other networks or computers.
Logical ports are numbered and assigned to specific services
What is bandwidth - Answers The maximum rate of data transfer that can occur across a network
(usually measured in Mbps or Gbps)
What is a daemon - Answers a background process that runs without the need for user interaction
-example: Apache, Nginx
What is ICANN? - Answers Internet Corporation for Assigned Names and Numbers:
Responsible for the coordination of maintenance and methodology of several databases of unique
identifiers related to the namespaces of the Internet, and ensuring the network's stable and secure
operation.
Provide IP addresses
Oversees IANA
What is the purpose of an IP address - Answers It uniquely identifies the location of each computer or
device connected to the Internet
Used as a unique identifier (destination) for packets to go to
What is a private network? What makes a network private? - Answers A private network is a network
that is isolated and restricts access only to authorized users. The IP range of a network makes it easy
to identify if it is private or not.
10.0.0.0 - 10.255.255.255 (10.0.0.0/8)
172.16.0.0 - 172.31.255.255 (172.16.0.0/12)
192.168.0.0 - 192.168.255.255 (192.168.0.0/16)
What is the purpose of a subnet mask - Answers A subnet mask identifies which bits in an IP address
are to be used to represent the network/subnet portion of an IP address.
