Study Notes

WhatsApp is a popular messaging app that allows users to communicate with friends and family via text, voice calls, and video calls.
It is a widely-used social media platform for personal and professional communication.

HDD vs SSD

HDD (Hard Disk Drive) stores data on spinning magnetic disks, while SSD (Solid State Drive) uses flash memory chips for data storage.
SSDs are generally faster and more durable than HDDs.
SSDs are more expensive than HDDs, but they are becoming more affordable over time.

Operating Systems

An operating system (OS) is a software program that manages a computer's hardware and software resources.
Common examples of operating systems include Windows, macOS, Linux, and Android.
OS acts as an intermediary between the user and the computer, allowing users to interact with the hardware and software.

RAM

RAM (Random Access Memory) is a type of computer memory that is used for temporary data storage.
Programs and data are loaded into RAM for quick access by the Central Processing Unit (CPU).
More RAM allows your computer to handle more programs and data simultaneously, leading to better performance.

Search Engines

A search engine is a software program that helps you find information on the internet.
Google is a popular search engine that uses algorithms to index websites and provide relevant search results based on keywords.
Search engines rely on a network of crawlers that continuously traverse the internet and collect data.

Video Editing Software

Video editing software allows you to modify and enhance video footage.
Popular examples of video editing software include Adobe Premiere Pro, Final Cut Pro, and Davinci Resolve.
These programs offer features such as trimming, cutting, adding transitions, applying effects, and adding soundtracks.

Antivirus Software

Antivirus software is a program that protects computers from malicious software (malware) such as viruses, worms, and Trojans.
It typically scans your computer for suspicious files and removes or quarantines them to prevent potential harm.
Antivirus software often comes with features such as real-time protection, firewall, and malware removal tools.

Phishing

Phishing is a type of cybercrime where attackers attempt to steal personal information, such as login credentials or credit card details, by pretending to be legitimate organizations.
Phishing attacks often come in the form of emails, text messages, or websites that mimic legitimate websites but are actually designed to trick users into revealing their data.
You should be wary of suspicious emails, text messages, or websites, and never provide personal information to websites that you are unsure of.

Technology's Impact on Communication

Technology enables instant communication worldwide through social media, messaging apps, and video calls.
Examples of video calling platforms include WhatsApp and Zoom.

Online Education

Online education provides flexible learning opportunities from anywhere, anytime.
Platforms like Coursera and edX offer diverse courses.

Storage Devices

HDD (Hard Disk Drive):
- Stores large amounts of data.
- Slower than SSD due to moving parts.
- Typical capacities range from 500GB to 10TB or more.
SSD (Solid State Drive):
- Faster than HDD due to flash memory and no moving parts.
- Boosts computer startup and file loading speed.
- Average capacities range from 250GB to 4TB.
Flash Memory:
- Non-volatile storage retaining data even without power.
- Used in SSDs, USB drives, and other devices.
Hard Drive:
- Stores files, applications, and the operating system in a computer.
External Storage:
- Portable storage devices (external hard drives, USB flash drives) for data outside the computer.

Cloud Storage

Stores data on remote servers accessible through the internet.
Offers flexibility and accessibility to data.
Examples include Google Drive, Dropbox, and Microsoft OneDrive.

RAID (Redundant Array of Independent Disks)

A storage technology combining multiple drives to improve performance and provide redundancy.

NAS (Network Attached Storage)

A storage device connected to a network, allowing multiple users to access and share files.

File Storage Units

Bit: Smallest unit of data.
Byte: Consists of 8 bits, the basic unit for measuring file sizes.
Kilobyte (KB): 1024 bytes.
Megabyte (MB): 1024 KB.
Gigabyte (GB): 1024 MB.
Terabyte (TB): 1024 GB.
Petabyte (PB): 1024 TB.

Speed and Performance

Data Transfer Rate: Speed of data transfer between devices, measured in Mbps or Gbps.
Mbps: Megabits per second.
Gbps: Gigabits per second (faster rate).
Access Time: Time taken for a storage device to find and retrieve data.
Cache: Fast memory in the CPU or storage devices, storing frequently used data for quicker access.
Read/Write Speed:
- HDD: Typically ranges from 80 MB/s to 160 MB/s.
- SSD: Ranges from 500 MB/s to over 7,000 MB/s.
