provides services and resources to
other computers on a network.
What is meant by
‘Internet of Things’
(IoT)?
IoT refers to the network of physical
objects that are connected to the
Internet and can collect and
exchange data.
What is bandwidth?
Bandwidth is the maximum rate of
data transfer across a network path.
What is a network
interface card
(NIC)?
A NIC is a hardware component that
allows a computer to connect to a
network.
What is a switch in
networking?
A switch is a device that connects
devices within a network and uses
packet switching to forward data to
its destination.
What is a firewall?
A firewall is a security system that
monitors and controls incoming and
outgoing network traffic based on
predetermined security rules.
What is an IP
address?
An IP address is a unique string of
numbers separated by periods that
identifies each computer using the
Internet Protocol to communicate
over a network.
What is an example
of an Internet
service?
Examples of Internet services
include email, file transfer, and web
browsing.
What is a web
browser?

Protocol Secure, which uses
encryption to secure data
transmission over the Internet.
What is VoIP?
VoIP stands for Voice over Internet
Protocol, which allows voice data to
be sent over the Internet.
What is the difference between a wired and wireless network?
A wired network uses physical cables, while a wireless network uses radio waves.
What are the benefits of a computer network?
Resource sharing, communication, data storage, and data security.
What is a DNS server?
A server that translates domain names into IP addresses, allowing users to access websites using human-readable names.
How is data transmitted across networks?
Data is transmitted in small packets that travel across the network to their destination.
What is a network switch?
A device that connects devices in a network and uses packet switching to forward data to its destination.
Explain the term “packet” in networking.
A small unit of data transmitted over a network, containing a portion of the message and control information.
What is a VPN?
A Virtual Private Network, which creates a secure connection over a less secure network, such as the internet.
What is network latency?
The time it takes for a data packet to travel from the source to the destination.
What is a MAC address?
A unique identifier assigned to a network interface card (NIC) for communications on the physical network segment.
What is a network topology?
The arrangement of different elements (links, nodes, etc.) in a computer network.
