How to Download Videos Safely
Steps
-
1Identify what video you want to download. Depending on the video there are different ways to download the video. For example, to download a movie or episodes from a TV series it is best to use torrents. To download Music Videos it is best to download the video from YouTube, or use Mediafire.
-
2Download a movie and/or an episode from a TV series(optional). Use a torrent site, such as http://www.isohunt.com/ and do a search for the video you are looking for. To ensure the video is safe, be sure to read the comments on the torrent before downloading it. If the majority of comments state that the video is safe and virus-free then download the torrent. Open the torrent with the necessary software - such as BitTorrent (http://www.bittorrent.com/btusers/download - it's free!). Wait until the download is finished and you have your video.
- 3Downloading a video off YouTube (optional). There are two ways to download a video from YouTube:
- Go onto YouTube and find the video you want. Use a YouTube video downloading site, such as http://www.mediaconverter.org/ and follow the instructions to obtain the video from YouTube. Note: videos off YouTube are sometimes of relatively low quality.
- Sometimes uploaded videos have a '+DL' (or similar) in the title. This means that the uploader has kindly included a link to download the video from an external website - this usually yields videos with greater quality.
-
4Downloading a music video (optional). If using YouTube is not your thing, then you can try using external websites. For Korean, Chinese & Japanese music videos, try using http://ihoneydew.com/ or http://jenpoo.com/. But if it is something else you are after, try using MediaFire (google it) by either accessing the website directly, or googling the MV's title + mediafire (e.g google: poker face mv mediafire).

COMPUTER NETWORKING.
Definition - What does Computer Network mean?
A computer network is a group of computer systems and other computing hardware devices that are linked together through communication channels to facilitate communication and resource-sharing among a wide range of users. Networks are commonly categorized based on their characteristics.
A network is a group of two or more computer systems linked together. There are many types of computernetworks, including:
What is a Local-Area Network (LAN)?
A local-area network (LAN) is a computer network that spans a relatively small area. Most LANs are confined to a single building or group of buildings, however, one LAN can be connected to other LANs over any distance via telephone lines and radio waves. Asystem of LANs connected in this way is called a wide-area network (WAN).
Most LANs connect workstations and personal computers. Eachnode (individual computer ) in a LAN has its own CPU with which itexecutes programs, but it also is able to access data and devicesanywhere on the LAN. This means that many users can share expensive devices, such as laser printers, as well as data. Users can also use the LAN to communicate with each other, by sending e-mail or engaging in chat sessions.
LANs are capable of transmitting data at very fast rates, much faster than data can be transmitted over a telephone line; but the distances are limited, and there is also a limit on the number of computers that can be attached to a single LAN.
What is a Wide Area Network (LAN)?
A computer network that spans a relatively large geographical area. Typically, a WAN consists of two or more local-area networks (LANs).
Computers connected to a wide-area network are often connected through public networks, such as the telephone system. They can also be connected through leased lines or satellites. The largest WAN in existence is the Internet.
What is a Campus Area Network (LAN)?
Acronym for campus-area network. An interconnection of local-area networks within a limited geographical space, such as a school campus or a military base.
What is a Metropolitan Area Network (LAN)?
Short for Metropolitan Area Network, a data network designed for a town or city. In terms of geographic breadth, MANs are larger thanlocal-area networks (LANs), but smaller than wide-area networks (WANs). MANs are usually characterized by very high-speed connections using fiber optical cable or other digital media.
What is a Home Area Network (LAN)?
Short for home area network. A HAN is a network contained within a user's home that connects a person's digital devices, from multiple computers and their peripheral devices to telephones, VCRs, televisions, video games, home security systems, "smart" appliances, fax machines and other digital devices that are wired into the network.
Testing my computer motherboard and CPU for failures?
A bad computer motherboard or CPU can cause an assortment of different issues on your computer. Below are just a few of the possible issues you may encounter. It is important to remember that the issues below can also be caused by more than just a bad motherboard and CPU.
- Computer does not boot, instead you get a beep code. See the POST and beep code page for additional information about beep codes.
- Random computer crashes causing General Protection Fault error messages, Illegal Operations, Fatal Exceptions, etc.
- Computer randomly reboots.
There are several different ways to test your computer's motherboard and CPU to determine if it's bad or has flaws that are causing issues with your computer. Below is a listing of these recommendations.
Software and Hardware solutions
Below is a listing of a software programs available that are designed to test your computer's motherboard and CPU. However, with the complexity and wide variety of computer motherboards and CPUs, these programs may not detect every possible failure.
- Hot CPU Tester - Our software recommendation for testing a computers motherboard and CPU. This is a great tool. Easy to run and use for looking for failures with your computer. In addition to testing a computer, this program also includes a burn-in feature for new computers or computers with a new motherboard or CPU.
In addition to the above solutions, there are other fantastic 100% commercial products. Below is a listing of some of these products.
- PC-doctor - A fantastic but not cheap solution often used for service centers and technicians to diagnose computer hardware issues including motherboard issues.
- PC Diagnostics - Another company that offers both hardware and software solutions for testing the majority of the hardware in your computer including the motherboard.
- Ultra-X - Another great collection of products that can help test computer hardware including the motherboard.
Replace the motherboard and CPU
If the motherboard or CPU is bad after trying the above suggestions, we suggest replacing it.
Troubleshooting a bad video card
Note: This page is for troubleshooting a bad video card, before following the steps below we suggest you go through the no display troubleshooting steps. No display can be a monitor related issue, not a post issue, or a video card related issue.
Caution: Each of the steps will require that you open and work inside your computer. While inside the computer make sure you're aware of the potential ESD dangers.
Reseat the video card
If your video card is not an on-board video card, verify that your video card is not loose by removing the video card from the computer and then re-inserting the video card back into the same slot it was removed.
Exchange video
If reseating the video card has not resolved the issue, or your video card is on-board and you have access to another known working video card, try an alternative video card in the computer.
Replace video card
If an alternative video card didn't work or you do not have an alternative video card to try, we suggest purchasing a new video card to replace the defective video card in the computer.
If an alternative video card didn't work, and replacing the video card with a new one did not resolve the issue, it's likely a defective motherboard and should be replaced.
Replace motherboard
If all the above steps have not resolved the issue, you have a bad motherboard. If you feel comfortable replacing the motherboard you can find buying tips for motherboardshere. Otherwise we suggest having the computer serviced at a local computer repair shop.
My computer monitor randomly shuts off
There are several possible reasons why a monitor would turn off randomly. Some of the reasons relate to the monitor while others relate to the computer.
Tip: If the monitor is staying on, but loosing signal (e.g. the power light goes from green to orange) this is almost always an issue with the computer and not the monitor. If the monitor power light turns off, then it is almost definitely a problem with the monitor.
Monitor overheating
One reason the monitor could shut off is because it is overheating. When a monitor overheats, it will shut off to prevent damage to the circuitry inside. Causes of overheating can be dust build-up inside the monitor, external heat or humidity where the monitor is used (especially on a hot summer day), or other blockage of the slits or holes that allow the heat to escape.
If the monitor is overheating, it is best to unplug the monitor and let it cool down fully before using again. Then, if you have canned air (anti-static, for electronics), try to blow out any dust that may be inside the monitor casing. If the room where the monitor is being used is very hot, find a way to cool it down, either by turning on a fan or the air conditioning system. Wait until the room cools down some before trying to use the monitor again.
Also, if you're using an older CRT monitor, upgrading to a newer flat panel display will resolve many heat related issues in a hot environment.
Loose cable
Although not as common, if the power cord is loose and is not securely connected to the back of the monitor it will cause the monitor to turn off. This can cause a loss in power, resulting in the monitor shutting off. Make sure the power cord is firmly in place in the back of the monitor. It's also possible that the power connector in the monitor is going bad and not receiving adequate power from the power cord. In this case, it is typically best to replace the monitor instead of having it repaired.
Bad Monitor
Another reason the monitor could shut off is because of a malfunction in the circuitry. There could be a short in the wiring or some other failure in the circuitry, causing the picture to go black or causing the monitor to shut off completely. In this case, there may not be much you can do other than buying a new replacement monitor. Monitors are usually not economical to have repaired since the repair cost can cost more than the price of a new monitor. You could bring the monitor to a computer repair shop to have it looked at, but most likely they will also recommend replacing the monitor.
COMPUTER OPERATING SYSTEM
An operating system or OS is a software program that enables the computer hardware to communicate and operate with the computersoftware. Without a computer operating system, a computer and software programs would be useless. In the picture to the right, is an example of Microsoft Windows XP, a popular operating system and what the box may look like if you were to visit a local retail store to purchase it.
When computers were first introduced the user interacted with them using a command lineinterface, which required the user to perform a series of commands in order to interact with the computer and its hardware and software. Today, almost every computer is using a Graphical User Interface (GUI) operating system that is much easier to use and operate.
Examples of computer operating systems
Microsoft Windows 7 - PC and IBM compatible operating system. Microsoft Windows is the most commonly found and used operating system.
Apple MacOS - Apple computer operating system. The only Apple computer operating system.
Ubuntu Linux - A popular variant of Linux used with PC and IBM compatible computers.
Google Android - operating system used with Android compatible phones.
iOS - Operating system used with the Apple iPhone.

How to Check a PC Operating System
An operating system (OS) is software that manages the interaction between hardware resources and the programs or applications you use on a computer. Most PCs have a version of the Windows operating system on them but Macintosh, Linux and UNIX are other popular operating systems. Besides learning the name of your operating system, such as whether you have Windows 7, you can find other useful information about your system. If you are worried about taxing your computer's central processing unit (CPU), for example, you may be able to check your operating system's bit version. A 64-bit version of Windows can process higher amounts of random access memory (RAM) better than a 32-bit version. Follow these methods to check a PC operating system.
Steps
-
1Turn on your PC. Watch as the computer starts up.Ad
-
2Check whether your operating system name, such as "Windows Vista," is displayed. If you do not see your operating system or want more details about it, let your computer finish starting up.
-
3Click the "Start" button if there is one. It is found in the lower left corner of the Desktop. A "Start" button means you have the Windows 95 OS or later.
- If you do not have a "Start" button, look for other indicators that show what operating system you have.
- A Microsoft Windows logo or flag may mean you have a version of Windows that predates Windows 95, such as Windows 3.11.
- If you see a red hat in a corner of your screen, you are running the Red Hat Linux operating system.
- If you see a green or blue "L" in a screen corner, you have Lindows or Linspire.
- A gray or black footprint in a screen corner indicates you are using a graphical user interface (GUI) called GNU Network Object Model Environment (GNOME) on a form of Linux or UNIX.
- The Sun Solaris operating system is being used with X, a graphics system for UNIX, if you have a purple background with "Sun" or "Solaris" being visually indicated on your screen.
-
4See if there is text written down the side of the "Start" menu. The text may name your PC's operating system and edition such as "Windows 95," "Windows 2000 Professional," "Windows XP Home," etc.
- If you are not sure if the text shown is the name of your operating system or you want more information on the OS, try 1 of the options below.
-
5Type "winver" without quotation marks in the "Start" menu's search box, then press "Enter."
- You may need to choose "Run" in the "Start" menu, then type in "winver" without quotation marks. Press "Enter."
-
6Look for an "About Windows" window to appear. The name of the OS should be in the top portion of the window.
- The version number of the operating system will be shown after the word "Version" and any service pack that has been installed as an upgrade will be displayed in parentheses. An example would be "Version 6.0 (Build 6001: Service Pack 1)."
-
7Right click the "My Computer" icon as an alternative. It can usually be found on your Desktop or in your "Start" menu.
-
8Select "Properties" from the menu that appears.
-
9Look at the "System Properties" window that displays. More detailed information on your operating system can be found under the "General" tab after "System:" or "System type," such as whether you are running a 64-bit or 32-bit version of Windows.
- See what operating system edition you are running near the top of the window under "System:" or "Windows edition." An example is "Windows XP Home."
- If running an edition of Windows XP, look for "x64 Edition" to see if you have the 64-bit version. If it is not there, you have the 32-bit version.
- For an edition of Windows Vista or Windows 7, look for "64-bit Operating System" or "32-bit Operating System" next to the words "System type."
