Basic Computer Operation Quiz

Study Notes

Access data stored on local drives, external devices, or cloud services, including files and media.
Connect to the internet for web browsing, downloading files, and online communication with browsers.
Communicate with peripherals like printers and scanners for printing, scanning, and other tasks.
Save and back up data regularly to prevent loss; options include local storage or cloud services.
Properly shut down the computer by closing programs and saving changes to ensure a safe exit.
Troubleshoot issues that may arise due to hardware/software problems, driver issues, or system failures.
Maintain security with antivirus software and firewalls to protect data from unauthorized access.

Slow performance usually results from a lack of storage space, outdated hardware, or malware infections.
Malware and viruses may lead to data loss, crashes, and identity theft.
Hardware failures can impact system stability, data integrity, and functionality.
Software glitches may cause applications to crash or malfunction, leading to data loss.
Internet connectivity issues result in slow-loading pages and interrupted downloads, affecting online access.

Data consists of raw, unorganized facts with no inherent meaning (e.g., sales figures).
Information is processed and organized data that provides context and meaning for decision-making (e.g., sales trends represented in graphs).
Properly formatted data can enhance its value and usefulness in analysis.

Digital Computers process information in discrete digital forms (0s and 1s) and are suitable for large data processing in various fields.
Analog Computers handle a continuous spectrum of data generated by physical processes (e.g., thermometers) and excel in real-time simulations.
Hybrid Computers combine analog and digital technologies, offering the speed of analog and the accuracy of digital computing.

RAM is a volatile memory that is faster and directly connected to the CPU, facilitating quick data processing.
Hard Disk is a non-volatile storage device used for long-term data retention, slower than RAM and not connected to the CPU.
RAM loses its data when the computer is turned off, while a hard disk retains information even when the device is powered down.

System Software is essential for operating devices (e.g., operating systems like Windows and Linux).
Application Software is not critical for the device's operation but assists users in various tasks (e.g., social media apps, games).

Hackers typically warn users about security risks without stealing information.
Crackers aim to steal information and compromise systems without user knowledge.

Speed is measured in GHz and MHz, enabling rapid task completion that far surpasses human capabilities.
Accuracy in computing reduces errors compared to human error due to incorrect data input.
Memory allows for the storage of vast amounts of data, measured in bytes.
Versatility enables the execution of multiple tasks simultaneously.
Automation is enhancing efficiency as AI technologies continue to evolve.

Multitasking capabilities allow simultaneous operations, increasing productivity.
Speed facilitates rapid completion of complex tasks.
Cost-effectiveness enables significant data storage at a reasonable expense.
Accuracy in processes leads to more reliable outcomes.
Data security measures help protect information from unauthorized access.
Enhanced communication and collaboration features streamline interactions between users.

Vulnerability to viruses and hacking poses risks to data integrity and user privacy.
Cyber crimes, such as fraud and cyberstalking, exploit online vulnerabilities.
Jobs may be threatened due to automation and reliance on technology.
Initial costs for purchasing computers remain high for many individuals.
The potential for distractions can lead to inefficiency and time wastage.
