How To Silence A Noisy Laptop Fan

I’ve had laptops for a good few years now, and never really looked back. The portability and masses of space I save outweighs my desire for a desktop PC and separate monitor.

The only thing that annoys me about my current laptop is the noise it kicks out when things start happening. This noise is my laptop cooling fan, which indicates that my laptop is hot. If it’s really loud then it’s too hot, and that’s not a good thing.

After years of dealing with this problem, I’ve learned that there are a few things you can do to silence that cacophony on your desk and hopefully stop your laptop from falling victim to heat exhaustion.

How to Secure a Wireless Network

Secure a wireless computer network by password protecting it when it is first created. Make sure a wireless computer network is secure with tips from a computer specialist in this free video on computer networking.

How Does Wireless Work?

Wireless systems carry data over radio waves.

Wireless networks, commonly known as Wi-Fi, are increasingly popular for home networks. Several members of the household can share an Internet subscription, each using their own computer in different parts of the house without having to run cables all over the building. Everyone know that "wireless" does not use wires, but what does it use?

1. Data Packets

   • In cabled networks, data travels around the network in a structure called a packet. The packet body contains a segment of data and network software puts headers on the front of the packet. The headers contain administration data. This includes the source and destination address for the packet, and also identifiers for the two applications communicating over the network. Wireless networks use exactly the same structure of a data packet. The only difference between wired and wireless networks is the network medium.

How Does a Wireless Communication Card Work?

How wireless cards connect with a computer

• A wireless communication card works with a USB or PC card slot to connect a computer to the Internet. The card is inserted into the USB port on a computer or a slot. The slots on old computers are for PCMCIA cards, which are roughly 2 inches in width. The newer computers have Express cards, which are only a little wider than an inch. Both the PCMCIA and Express card are more convenient than the USB wireless cards because they don't protrude very far out of the slot on your computer. USB wireless cards can be bumped into things, especially when connected to a laptop. The upside to the USB style of wireless card is the fact that newer computers are coming out with more USB ports. Still, the PCMCIA and Express cards are most durable for anyone traveling with wireless Internet.

How to Share a Mobile Internet Connection

A mobile Internet connection can be shared via a wired or wireless ad hoc network

Sharing a mobile Internet connection is a good way to take advantage of the high-speed data connections offered by mobile carriers. As long as you have a smartphone or Aircard with a data plan, you can share high-speed Internet access between computers wherever you have a cell signal. Sharing the connection requires an ad-hoc network to be established between all computers that will share the mobile Internet. The connection may be made via an Ethernet cable or wireless connection.

Instructions

1. • 1
     Enable Internet connection sharing on the host computer. Open the Control Panel and click on Network and Internet Connections. Next, click on Internet Connections and right-click the connection that you will be sharing (it will likely be called Mobile Broadband or WWAN, standing for wireless wide area network). Click Properties and open the Advanced tab. Check the box that allows other computers to use the host computer's Internet connection.

How Global Positioning System Work ?

When people talk about "a GPS," they usually mean a GPS receiver. The Global Positioning System (GPS) is actually a constellation of 27 Earth-orbiting satellites (24 in operation and three extras in case one fails). The U.S. military developed and implemented this satellite network as a military navigation system, but soon opened it up to everybody else.

How Cell Phones Work

A cell phone can work off of one of three different types of networks in the United States, including the GSM, CDMA and iDEN networks. Find out which cell phone providers work on which networks with information from a wireless specialist in this free video on cell phones.

  Cell phones are wireless and don't connect to any electrical lines. The best way to begin to explain how cell phones work is to look at your radio. Radios transmit through radio frequency. They have FM and AM frequencies. Cell phones also rely on radio frequency to work.

• The Federal Communications Commission of the United States regulates the amount of radio frequency that is allowed to be used by cell phones at one time. Cell phones use towers, which means that one tower would be regulated to let's say 3,000 phone calls at once. That may be enough for a small town with a population of less than 3,000 people, but it certainly wouldn't be enough for a large city like Chicago. The answer to that problem came in the creation of more cell phone towers.

Speed Up an Internet Connection

How to Speed Up an Internet Connection

If your Internet connection is slow, there are a number of methods to speed it up. Some of the following suggestions can be tried on the spot; others are more complex.

Instructions

Things You'll Need

• Cable Modems
• Modems
• DSL Lines
• ISDN Lines

1. • 1
     Configure your browser so it won't display graphics, animations, sound, video or other multimedia content (see "How to Turn Off Sounds, Pictures or Video on Web Pages").

RAR Files Passwords Recovery

A RAR video file is just like any other zipped file, and contains a video that is compressed and stored inside of multiple files that you have to "unzip" in order to view them. A RAR might also be stored in one or more files without compression, and may have been saved with other options, like encryption. An encrypted RAR video file is secured with a password that can only be removed after you crack the code.

Instructions

1. • 1
     Install RAR Password Recovery to crack the password of a RAR file that was created with any version of WinRAR, or other compatible versions (see Resources). It uses an advanced brute-force attack or a dictionary attack to recover the password. A dictionary attack simply tries every word in the dictionary, while brute-force tries every possible combination of letters and numbers.

Manually Delete the Browser History in the Registry

To ensure your Internet browsing remains private, delete your browser history. The browser history is a list of URLs visited within the browser during a period of time. The Internet browser history is recorded in the Windows registry, but may be displayed through the browser by accessing the "History" area. The browser history may be deleted in two ways: either GUI-assisted from within the browser application or manually from within the Windows registry.

1. • 1
     Click the Windows "Start" button to open the "Search" input box.
   • 2
     Type "regedit" (without quotes) into the Search input box and press the "Enter" key. The Windows Registry Editor will open.
