A wireless network key is an encryption key for that prevents unauthorized users from accessing a specific wireless network. The user creates wireless network keys, which either a wireless router or a computer that is connected to that wireless router can manage. Wireless network keys can be any length greater than eight characters and can be used with both WEP and WPA encryption methods. A wireless network key serves as a password for a specific wireless network and prevents unauthorized users from accessing it. Wireless network keys can be used Read More

A harmonic balancer is a device that is connected to an engine’s crankshaft in order to reduce any vibration’s negative impact on the crankshaft and to dissipate the energy that shaft rotation creates. Since the device is the engine compartment’s first element that is connected to the shaft, it absorbs the majority of the energy generated during engine use. By absorbing this energy, only the harmonic balancer (instead of more vital engine components) fails, thereby preventing catastrophic engine failure. How does the Harmonic Balancer Work? The harmonic balancer is made Read More

GBE stands for Gigabit Ethernet, which is a general term for a group of standards which allows for networking at speeds of up to one billion bits (one gigabit) per second between devices on a Local Area Network. Gigabit Ethernet can also be abbreviated as GbE or 1 GigE. Gigabit Ethernet is one of the latest implementations of the Ethernet standard, a frame-based computer networking technology originally developed at the prolific and creative Xerox Palo Alto Research Center in the 1970’s. The name is derived from the late 19th century Read More

In C++, file input/output services are implemented through a component header file available C++ standard library. This header file is fstream.h . In C++, a file, at its lowest level, is interpreted simply as a sequence, or stream, of bytes. One aspect of the file I/O library manages the transfer of these bytes. At this level, the concept of a data type is absent. On the other hand, file, at the user level, consists of a sequence of possibly intermixed data types – characters, arithmetic values, class objects etc. A Read More

Macrovision is a company that sells copy protection products. The company's first product was a copy protection system for VHS tapes, which was also known as Macrovision. For a detailed look at that system, read Antti Paarlahti's Macrovision FAQ. The Macrovision copy protection system was later extended to DVDs. Macrovision is designed to prevent DVDs from being copied to tape. How Macrovision Works Macrovision works by making modifications to the video signal, including: Automatic Gain Control: Macrovision inserts pulses into the vertical blanking signal. This confuses the synchronization and automatic-recording-level Read More

A web browser is, as the name suggest, a program used by a computer to browse the web. It is responsible for retrieving, presenting and sending information from the World Wide Web. For example, a web browser contacts the server a website has, receives the code, translates it into something that can be viewed and then, when the user submits something, it sends that information back. In 1993, the NCSA Mosaic web browser was released. This was the first graphical web browser and it caused an explosion in Internet use. Read More

The need may arise to use a nonstandard connection with a device. Such a need can occur when a Firewire connectible device is used in a USB connector or vice versa. An adapter is the most useful option for those who need to connect a Firewire device to a USB port or a USB device into a Firewire port. Hub Devices Hub devices are designed to add additional ports to the computer via a USB interface. The hub hardware can connect the Firewire device and the computer when it is Read More

Cisco VPN error 412 occasionally occurs when using the Cisco VPN client. The exact error message may differ between versions of the Cisco VPN client, but will be similar to this: Error Secure VPN Connection terminated locally by the Client. Reason 412: The remote peer is no longer responding. Causes for Cisco VPN Error 412 There are many error 412 causes, including: Poor network connection. Packet delay or loss can force the VPN session to drop. Hardware failure in a network interface card or network device. A firewall or ACL Read More

One of the things that many computer users do once they record or download a video is edit it to fit their needs. Whether someone is making a home movie, creating a mash up, or adding features such as subtitles, he/she will need to edit the video file. Here are some tips on editing one of the most common video files available – WMV. What is a WMV File? Before playing WMV files, it is important to know a little more about this format. Microsoft originally developed the WMV (Windows Read More

Hertz is the International System of Units (SI) base unit of measurement for frequency. Hz is the standard abbreviation for hertz. One hertz is defined as “one complete cycle per second,” and can be applied to any periodic event, but is usually applied to sound waves, electrical current, and radio waves. The hertz is the frequency of the cyclical waves in these phenomena. History of the Hertz In 1930, the International Electrotechnical Commission (IEC) named the Hertz after Heinrich Hertz, a German physicist. In 1960, it was adopted by the General Read More
