II. Common Technology Terms
A. Hardware techiesstar
Definition and Examples
Hardware refers to the physical components of a computer
system that can be touched and interacted with. Examples include the central
processing unit (CPU), memory modules, hard drives, graphics cards, and
input/output devices like keyboards and mice.
Components and Functions
CPU: The "brain" of the computer that performs
calculations and executes instructions.
Memory: Stores data and instructions that the CPU needs to
access quickly.
Hard Drive: Provides long-term storage for data,
applications, and the operating system.
Graphics Card: Handles visual output, which is critical for
gaming and graphic-intensive tasks.
Input/Output Devices: Facilitate communication between the
user and the computer, such as keyboards, mice, monitors, and printers.
B. Software
Definition and Examples
Software refers to the non-physical instructions that tell the
hardware how to perform tasks. Examples include operating systems (OS), word
processors, web browsers, and video editing software.
Types: System Software vs. Application Software techtargetmedia
System Software: Manages and controls computer hardware,
e.g., operating systems like Windows, macOS, and Linux.
Application Software: Designed for specific tasks or user
needs, e.g., Microsoft Word, Google Chrome, and Adobe Photoshop.
C. Network
Definition and Examples
A network is a collection of devices connected to share
resources and information. Examples include the Internet, local area networks
(LANs) in homes or offices, and wireless networks (Wi-Fi).
Types: LAN, WAN, MAN, PAN
LAN (Local Area Network): Connects devices within a limited
area, like a home or office.
WAN (Wide Area Network): Spans larger geographic areas,
often connecting multiple LANs.
MAN (Metropolitan Area Network): Covers a city or large
campus area.
PAN (Personal Area Network): Connects devices close to
Bluetooth, such as devices.
Networking Devices
Router: Manages data traffic between devices on a network
and the Internet.
Switch: Directs data to specific devices within a network.
Modem: Connects a network to the Internet through an
Internet Service Provider (ISP).
Access Point: Provides wireless connectivity within a
network.
Firewall: Protects a network by filtering incoming and
outgoing traffic for security.
Understanding these foundational technology terms lays the
groundwork for navigating the digital world and leveraging technology to its
fullest potential.
B. Software worldwidewebblog
Types: System Software vs. Application Software
Regarding software, there are two main categories: system and
application. Each serves a distinct purpose in the functioning of a computer
system.
a. System Software:
System software acts as an intermediary between hardware and
application software. It manages and controls the computer's hardware
components, ensuring they work harmoniously. Critical functions of system
software include managing memory, handling hardware drivers, and providing
essential services to applications and users. The most prominent example of
system software is the operating system (OS).
Operating System (OS): The core software that manages
hardware resources, provides a user interface and enables users to run
applications. Examples include Windows, macOS, Linux, and Unix.
Device Drivers: Software that allows the operating system to
communicate with hardware devices, ensuring proper functionality and
compatibility.
b. Application Software:
Application software, or "apps," is designed to
perform specific user tasks. Unlike system software, application software is
developed to cater to the needs and interests of individuals, businesses, and
organizations. These programs use the resources the system software provides to
carry out tasks effectively and efficiently.
Word Processing Software: Enables users to create, edit, and
format text documents. Examples include Microsoft Word, Google Docs, and
LibreOffice Writer.
Web Browsers: Allow users to access and interact with
websites and online content. Examples include Google Chrome, Mozilla Firefox,
and Microsoft Edge.
Multimedia Software: Handles audio, video, and image-related
tasks. Examples include Adobe Photoshop, VLC Media Player, and Adobe Premiere
Pro.
Productivity Software: Helps users organize tasks, manage
projects, and enhance efficiency. Examples include Microsoft Excel, Evernote,
and Trello.
Gaming Applications: Provide entertainment through
interactive gameplay. Examples range from casual mobile games to complex PC and
console games.
In summary, system software forms the foundation of a
computer system, managing hardware resources and providing a platform for
application software to run. Application software caters to specific user needs
and preferences, allowing individuals and organizations to accomplish various
tasks efficiently. Together, these two types of software enable the
functionality and utility of modern computers and devices.
