The different ways hardware, software,
and systems may connect and interact
these are called
connectivity and networking
This is one of the most popular forms of
wired networking, connecting devices to
a local area network (LAN) or the
internet using cables (often CAT5e or
CAT6). It provides dependable, fast
connectivity.
Ethernet
These connections, which provide
incredibly high capacity and
long-distance communication, convey
data via light signals. They are
frequently used in data centers and for
high-speed internet backbones.
Fiber Optic
Cable television and high-speed internet
connections frequently employ coaxial
wires. Their bandwidth and signal
quality are both excellent.
Coaxial Cable
Types of Wired Networking
Ethernet, Fiber Optic, Coaxial Cable
Meaning of LAN
Local Area Network
With the help of this, devices may
connect wirelessly to the internet or a
local network without the need for
physical wires. In businesses,
residences, and public spaces, it is
extensively utilized.
Wi-Fi (Wireless Fidelity)
A short-range wireless technology
called ______ links items like
headphones, keyboards, and
cellphones.
Bluetooth
This permits wireless short-range
communication between devices,
frequently used for data transmission
and contactless payments.
NFC (Near Field Communication)
These wireless communication
protocols are intended for low-power,
low-data-rate uses, such as the Internet
of Things (IoT) and smart homes.
Zigbee and Z-Wave
____________ technologies including
3G, 4G LTE, and 5G give mobile
devices wireless internet connection.
Data speed and coverage areas vary
between them.
Cellular Network
Internet connection in remote or rural
locations where wired or cellular
networks would not be accessible is
made possible by this technology, which
makes use of satellites circling the
Earth.
Satellite Networking
Devices connect with one another
directly in ____ networks without the
need of a central server. This kind of
networking is frequently utilized for
decentralized apps and file sharing.
P2P
These establish private, secure
connections across a public network,
often the internet. In order to provide
remote access to private networks and
safeguard the privacy of data, they are
frequently utilized.
VPN (Virtual Private Networks)
This is a networking strategy that
divides the data plane, which sends
data packets, from the control plane,
which controls network traffic. More
flexibility and control over network
resources are provided by it.
Software-Defined Networking
Machines, sensors, and control systems
are connected via industrial networks in
manufacturing and automation
environments. Examples include
Profibus, Modbus, and Ethernet/IP.
Industrial Networking
_________ provide limited access to the
public whereas _________ are internal
networks that are only accessible by
members of the company. They serve
as a platform for corporation and
internal communication.
Extranet, Intranet
__________ have become
increasingly important as our reliance
on computers has grown.
Understanding topics such as
encryption, firewalls, and best practices
for safe computing is critical for
safeguarding personal and sensitive
data.
Security and Privacy
refers to the policies and
procedures used to guard against
unwanted access, assaults, and
damage to computer networks,
systems, and data.
Cybersecurity
Implementing _____ to
filter network traffic and prevent
malicious access.
Firewalls
Using ______
programs to detect and remove
malware.
Antivirus
Encrypting sensitive
data to make it unreadable to
unauthorized users.
Encryption
Implementing
strong user authentication and
authorization systems.
Access Controls
Having plans
in place to address and recover from
security breaches.
Incident Response
