Can computers make you feel sick?

Yes, computers can possibly make you feel sick. For instance, fast-moving images and droning sounds might make some people feel nauseous. If someone is prone to motion sickness, they might want to avoid certain videos or games. Plus, don't forget that certain types of flashing images could possibly trigger epilepsy.

There are other ways computers might make you feel less than well. For instance, if you stare at a computer screen for a long time, your vision may seem reduced for a few hours after. Improper posture and keyboarding techniques can aggravate existing health problems.

Different types of BIOS?

Different Types of BIOS

The Basic Input/Output System (BIOS) is a fundamental software component embedded on a non-volatile memory chip on the motherboard of a computer. It acts as an intermediary between the operating system and the computer hardware, playing a crucial role in the booting process. While the core functions remain largely consistent, different types of BIOS exist, each with its own unique features and functionalities.

Here's a detailed look at the various types of BIOS:

  1. Traditional BIOS (Legacy BIOS)

Traditional BIOS, also known as legacy BIOS, is the oldest and most prevalent type. It uses the Intel x86 architecture's Basic Input/Output System (BIOS) interface, communicating with hardware through interrupt requests (IRQs) and Direct Memory Access (DMA).

Architecture: Character-based interface, relying on command-line prompts and keystrokes for navigation.

Boot Process: Traditional BIOS performs a Power-On Self Test (POST) to verify hardware functionality. It then locates and loads the operating system from the boot device, typically the hard drive, into the system memory.

Features: Limited configurability options, mainly focused on boot order, date/time settings, and basic hardware parameters.

Limitations:

Size: Limited ROM space restricts the amount of functionality and complexity.

Speed: Accessing and processing information can be slower compared to modern UEFI.

Security: Vulnerable to security threats due to its older design and limited security features.

Compatibility: Can face compatibility issues with modern operating systems and hardware.

Use Cases: Widely used in older computers and some specialized systems where legacy compatibility is crucial.

  1. UEFI (Unified Extensible Firmware Interface)

UEFI, introduced as a successor to traditional BIOS, offers a groundbreaking approach to firmware management. It integrates a graphical interface, enhanced security features, and improved boot performance.

Architecture: Modern, graphical user interface (GUI) for user-friendly navigation and configuration. Supports high-resolution displays.

Boot Process: UEFI also performs a POST, but with a faster and more comprehensive process. It supports booting from a wider range of storage devices, including solid-state drives (SSDs) and network boot.

Features:

Secure Boot: Verifies the authenticity of the bootloader and operating system to prevent malicious code from executing during boot.

EFI System Partition (ESP): Dedicated partition on the hard drive for storing UEFI boot files and EFI applications.

Larger Memory and Partition Support: Handles larger hard drives and supports GUID Partition Table (GPT) partitioning scheme.

Advanced Configuration Options: Offers granular control over hardware settings, boot options, and system performance.

Benefits:

Faster Boot Times: UEFI utilizes a faster file system and streamlined boot process.

Enhanced Security: Secure Boot and other security features protect against boot-time attacks.

Improved Hardware Compatibility: Supports a wider range of modern hardware components.

User-Friendly Interface: GUI simplifies configuration and navigation.

Use Cases:

Modern Computers: UEFI is the standard firmware for most new computers.

Secure Systems: UEFI's security features are essential for servers and systems handling sensitive information.

Virtual Machines: UEFI offers improved performance and compatibility within virtualized environments.

  1. Other Specialized BIOS Types

Besides traditional and UEFI BIOS, several specialized types exist, catering to specific hardware or use cases:

AwardBIOS: A popular legacy BIOS implementation known for its stability and extensive customization options.

PhoenixBIOS: Another widely used legacy BIOS, known for its robustness and support for various hardware platforms.

AMI BIOS: A comprehensive BIOS solution offering a wide range of features and customization options for both legacy and UEFI systems.

Coreboot: An open-source project aiming to replace proprietary BIOS with a modular and secure firmware.

Choosing the Right BIOS Type

The choice of BIOS depends primarily on the age and capabilities of the computer hardware.

Legacy BIOS: Suitable for older computers lacking UEFI support or requiring compatibility with legacy software and hardware.

UEFI: The preferred choice for new computers due to its enhanced performance, security, and user-friendliness.

Understanding the different types of BIOS allows users to better diagnose issues, optimize system performance, and make informed decisions about hardware upgrades and compatibility.

What device protects system against lightning strikes but does not protect against Sags and brownouts?

It's true that a surge protector would protect against surges like those caused by lightning strikes but would do nothing to help with sags and brownouts. To address both high voltage (surges) and low voltage (brownouts) you would need an uninterruptible power supply (UPS). A UPS provides clean current by powering your computer from the battery while simultaneously charging the battery from the electrical supply.

Can I use a 10 amp 125 volt power cord on my computer's 6 amp 125 volt input?

Yes, you can use a 10 amp 125 volt power cord on your computer with a 6 amp 125 volt input. The power cord's amp rating represents the maximum current it can handle, so it is suitable for your computer's lower amperage requirement. Just ensure the voltage matches to avoid any potential damage.

Can computer damage caused by a magnet be reversed?

Actual damage by a magnet to a computer is extremely rare, and thus it is impossible to gauge what type of damage you are referring to. Data erased from a disk by a magnet is likely not recoverable. You should be able to reinstall the operating system to the disk, but depending on the intensity of the magnetic field, the disk may need a passover with a degaussing coil to remove a strong magnetic field.

Magnetization to a CRT monitor (generally resulting in distorted colors) can usually be fixed by running the monitor's built-in degaussing coil (selectable in its OSD menu). A particularly strong field may require several degaussing sessions (the coil built in can only be run once every five minutes or so), or require the use of a dedicated degaussing coil. Any television technician should have such a coil.

256mb; 512mb; 1gb; 2gb; 4gb.

How do you format a blank hard drive?

If you mean "completely erase" it, the term is "Format" and you can perform it from DOS using the command "Format c:".

I think it is beyond formatting. I read today in the New York Times that John Jay College in NYC has adopted a program that covers the free space with zeroes.

The program your probably talking about is evidence-eliminator.com. This program erases all forensic evidence that remains on your hard drive after you format it, and believe you me it's alot. You can recover the entire contents of a formatted hard drive with the right tools. But EE prvents this and effectively "Zero's Out" you hard drive.

Formating a hard drive prepares it for use and deletes previous file names so Windows can't see them. They still exist and can be recovered with several Undelete programs. However, if you wish to remove all data from the drive, just formatting is not enough. "Zeroing" a drive rewrites over the entire drive, replacing previous data with simple 0's. There are several 'Zero' filling programs available on the web and some drive manufacturers include a zero utility on their support sites.The previous answer is pretty good, however it is argued that you can recover a zeroed hard drive. It is possible to retrieve "some" data however "fully recovering" a zeroed hard drive hasn't been done as far as i know.simply doing a "1 zero pass" will invert all the "1's" to "0's" (remember there are only 1's and 0's) hence "zeroing" however there is software available that can detect newly magnetized "0's" it simply re-inverts the "0's" to "1's" if you do a "7 zero pass" it's pretty much impossible to retrieve any information off the hard drive. look into the "DoD 5220.22-m" standard or "gutmann".hope this is useful.
