Known as the “brain” of the computer
Central Processing Unit (CPU)
Responsible for carrying out
computations and executing
commands
Central Processing Unit (CPU)
Short-term storage area where the
computer keeps active data and
instructions
Memory (RAM)
Hard drives, solid-state drives (SSDs),
etc
Storage Devices
Keyboards, mice, touchscreens, etc
Input Devices
Speakers, printers, displays
Output Devices
- Primary circuit board
- Links and enables communication
between all parts
Motherboard
is made up of programs, applications, and OS
software
controls hardware resources
Operating system (OS)
Type of Mobile Operating System
- iOS
- Android
- Blackberry OS
- Windows Phone OS
- Symbian
- WebOS
- Windows Mobile
serves as the raw material from
which information is derived and may
require processing to become useful
information
data
is the end result of processing data; purpose is to provide knowledge or facilitate decision-making
information
are created by programmers to train computers to do specified tasks; teaches the computer what to do
algorithm
are used to create code that implements these techniques
Programming languages
Python, Java, C++
Programming languages
enable computers to exchange information, resources, and services over long distance.
Computer Networks
Type of Connectivity and Network
- Wired Networking
- Wireless Networking
- Cellular Networking
- Satellite Networking
- Peer-to-Peer (P2P) Networking
- Virtual Private Networks (VPNs)
- Cloud Networking
- Software-Defined Networking (SDN)
- Industrial Networking
- Intranet and Extranet
Serve as a platform for cooperation and
internal communication
Intranet and Extranet
provide limited access to the public
extranet
are internal networks that are
only accessible by members of the
company
intranet
Connects machines, sensors, and
control systems in manufacturing and
automation environments
Industrial Networking
Networking strategy that divides the
data plane (sends data packets) from
the control plane (controls network
traffic
Software-Defined Networking (SDN)
Enables remote access to data and
apps for both organizations and people
Cloud Networking
Establish private, secure connections across a public network, often the internet
Virtual Private Networks (VPNs)
Devices connect without the need of a
central server
Peer-to-Peer (P2P) Networking
- Makes use of satellites circling the Earth
- Internet connection in remote or rural locations where wired or cellular networks would not be
accessible is made possible
Satellite Networking
- Gives mobile devices wireless internet connection
- Include 3G, 4G, LTE, 5G
Cellular Networking
a. Wi-Fi (Wireless Fidelity)
b. Bluetooth
c. NFC (Near Field Communication)
d. Zigbee and Z-Wave
Wireless Networking
- Permits wireless short-range
communication between devices - Frequently used for data transmission
and contactless payments
NFC (Near Field Communication)
Intended for low-power, low-data-rate
uses (such as Internet of Things or IOT
and smart homes)
Zigbee and Z-Wave
a. Ethernet
b. Fiber Optic
c. Coaxial Cable
Wireless networking
- Provides dependable, fast connectivity
- 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)
ethernet
- Convey data via light signals
- Provide incredibly high capacity and
long-distance communication - Frequently used in data centers and for
high-speed internet backbones
Fiber optic
- Bandwidth and signal quality are good
- Frequently employed in cable television
and high-speed internet connections
Coaxial Cable
Integral aspects of the digital age, with
both individuals and organizations
responsible for safeguarding data and
respecting privacy rights
Security and privacy
Policies and procedures used to guard
against unwanted access, assaults,
and damage to computer networks,
systems, and data
Cybersecurity
Includes defending physical assets,
data centers, and equipment from
damage or theft in addition to protecting
against digital threats
Physical Security
- Protecting the confidentiality, integrity,
and availability of information - Includes trade secrets, customer data,
and proprietary information
Information Security
Ensures safety of data transmission
across networks, preventing
eavesdropping or data interception
Network Security
