Video Multiplexer
A video multiplexer is a technology that can read more than one video signals and turn them into one. It has a lot of functions in the media section. It can also redirect the signals and multiply or to say amplify the signals in order to get a better view.
When a scene is shot by a video camera the shooting format is sometime quite different than the format we see in the TV or VCR or DVD player etc. It is the video multiplexer that alters the signals and turns them into a compatible format for TV or other home used objects. Most of the time the movies are not shoot in compatible formats but shot in extremely high resolution camera and in a high definition format that is unsuitable for our TV. It is the video multiplexer that makes it possible for us to watch those movies sitting right in our home.
Unix Emulator
Before we jump into UNIX emulators we have to know about UNIX as most of the people do not know what UNIX is. It is an operating system that was first created and developed in the late 60’s by a company called AT&T and a group of programmers named Ken Thompson, Dennis Ritchie, Brian Kernighan, Douglas McIlroy, and Joe Ossanna who are indeed the employees of Bell lab. Until then the UNIX operating system is developed, improved and customized by a lot of organization and programmers including the organization called AT&T.
Now as we have been learning enough about the UNIX operating system we can talk about the emulators as well. Basically emulating software refers to software that has the power or ability to compete with a certain type or the software of same criteria. There are three types of UNIX emulators and they are Cygwin, MKS Toolkit, and UWIN. All these have the UNIX like working method but a bit of difference that made them the UNIX emulators. They will provide a guideline for you to use the UNIX operating system.
Scan Disk
Scan Disc is a disk analysis and repair tool with main task to check a hard drive for errors and correct any problem found. Scan Disc is part of Microsoft Windows and MS-DOS. Scan Disk as a maintenance tool, it can repair files and find bad clusters, usually with great success. Errors like these often happen when Windows locks up and needs to be restarted.
Scan Disc, however is not suitable for NT based Windows versions (that includes Windows 2000, Windows XP) since it can’t check NTFS disk drives. For computers running NT based Windows excellent solution is new CHKDSK.
What is TKIP
What is TKIP
Temporal Key Integrity Protocol or TKIP is a protocol which is used for encryption. It is a part of Wireless LANs or WLANs’ IEEE 802.11i standard. The purpose of this design was to provide better security encryption than the disreputably vulnerable Wired Equivalent Privacy or WEP which was the original security protocol for WLANs. TKIP is an encryption method which is used by Wi-Fi Protected Access or WPA that replaced WEP in the products of WLAN.
TKIP is basically suite of algorithms which works as covering over WEP, which permits individuals of legacy WLAN tools to advance to TKIP without even replacing the hardware. TKIP basically uses the fundamental WEP programming but encapsulates the code with the additional code on the starting and in the end in order for modification in protocol. TKIP also uses RC4 stream encryption algorithm for its source just like WEP. Whereas the new protocol encrypts each and every data packets with a matchless encryption key. These keys are even stronger than the previous ones. TKIP has four additional algorithms to increase its key strength: Continue Reading “What is TKIP” »
Find MAC Address
Find MAC Address - MAC is an abbreviation of Media Access Control. MAC address is a particular address which is given to Network Interface Card (NIC) also known as network adapter. This MAC address is used to identify the personal computer.

Connect SCSI to USB
Computer cables have been redesigned and reorganized connections with the appearance of USB (Universal Serial Bus). These days, all of the computers have built-in USB ports. These days, almost many of the computer accessories are connected through USB ports.
The SCSI (Small Computer System Interface) cabling systems are not thus far outdated but almost all users generally prefer USB devices. It is not about the fame but there are apparent reasons behind the USB trend. To check out this growing consumer trend, it wouldn’t be bad but vital to look at USB very closely. USB port has a standard design for interface devices. It was designed for using a standard sized socket interface. The interface has proved to boost up the plug-and-play features and abilities of computer significantly. The USB became so much popular because while using it, no need is there to restart your computer whenever connecting and disconnecting the peripherals. This is the advancement which most users welcomed.
Mondex Smart Card
In 1990 England’s National Westminster Bank develops a smart card named as mondex. It was basically design as a virtual wallet or server as a electronic cash. Any sum of the cash can be channelized by the Mondex smart card. MasterCard international has purchased checking interest in leading firms; in 1997 Mondex International join those companies as Wells Fargo and AT&T in pursuance with the advancement of the technology.
The designing of the MONDEX smart card allow users to shift their cash electronically into the card and use the card up to the limit of the total cash which u have transferred in it.
