SHN is a .wav file compression process that helps to improve the way audio source files are stored. The following is some background on the concept of SHN and some suggested applications. What SHN does SHN is used in audio compression processes. The idea behind SHN (or Shorten) is to compress an audio .wav file without losing any type of data associated with the source file. This can be contrasted with the MP3 file, which usually discards some information associated with the source file; this lost information cannot be recovered Read More

A KVM switch is a keyboard, video and mouse switch. KVM switches are extremely useful when controlling one or more computers or servers. With a KVM switch you can easily connect one keyboard, video monitor and mouse to a multitude of computers or servers. Usually KVM switches can control up to 64 computers at one time and you can even daisy chain your servers for your KVM switch to control more than that if need be. KVM switches are great for technicians who work at a data center or are Read More

eSATA stands for External Serial Advanced Technology Attachment. It is meant to be an external interface for SATA technologies. SATA or Serial ATA (Advanced Technology Attachment) is the next generation of drive interfaces, its predecessor being the Parallel ATA (PATA). PATA Anyone who has opened up their computer must have noticed the flat, 40-wire parallel cables that are used to connect the hard disk, CDROM and other devices to their respective controllers; these are typical PATA connections. PATA has been the standard in connectivity for a while and served the Read More

Bluetooth is a wireless communication protocol that allows multiple devices to communicate with each other and share files when they are in range. While Bluetooth is a rather new technology, it has quickly become a feature that the vast majority of wireless devices support and can be used with laptops, cell phones, PDAs, Bluetooth-enabled desktops, cameras, video game consoles, printers, fax machines, GPS receivers, and other fixed and mobile wireless devices. Bluetooth is an open wireless standard and uses short-wave radio transmissions to communicate with nearby devices, allowing for fast Read More

SCSI (Small Computer System Interface) is a set of ANSI standards for connecting devices to computer systems. The vast majority of SCSI devices are data storage devices. Standard SCSI is a parallel technology, but many serial SCSI variants exist, including FireWire and Fibre Channel. SCSI is generally considered a higher-end alternative to IDE (Integrated Drive Electronics). A single IDE controller can control two drives. A single SCI controller can control 8 or 16 drives. In addition, SCSI usually offers greater cable length and higher length than IDE. SCSI Standards SCSI Read More

A quad core processor is a piece of hardware made up of three components. The first is the core, which in this case, there are four of them. Then these are bundled up and fit inside a die. The die is the silver tab you might see on your processor. Finally, this is added to the package which is the green material you see with all of the pins. This is your CPU; however, it is the individual cores that, when combined, make up the quad core processor. For a Read More

MRAM (Magnetoresistive Random Access Memory) is being considered as a viable replacement for current DRAM technology. Its key difference to the latter is its use of magnetic fields to save memory bits which makes the memory "permanent." As such, MRAM technology allows for faster access and data security. Current RAM Technology Current RAM technology uses an electrical charge to store memory bits. Microminiaturized capacitors and transistors in an integrated circuit are 'stacked up' to create high-density, large-memory but physically small chips. A typical memory chip stores up to 1 Gb Read More

A key concept in data storage is that it is linear, logical, and systematic in nature. When someone ‘saves’ data to the hard disk, the disk will follow a logical system. A hard disk can be compared to a large, square piece of graphing paper composed of squares, a thousand long and a thousand wide. Each square can accommodate one kilobyte of data and thus a ‘strip’ having a thousand squares can store one megabyte of data. In such a case, the disk head will ‘fill’ in the upper leftmost Read More

An interactive whiteboard is a digital device capable of interacting with a computer and projecting images in a screen. This device is used for visual presentation in classrooms, workgroups and business meetings. An interactive whiteboard needs to be connected to a computer which generates the actual images or data which are then projected to the board. Most interactive whiteboards have keyboard and mouse functionalities, but some models are capable of whiteboarding functions like character recognition so notes can be written or recorded on the physical board itself. How it Works Read More

Predictions regarding the demise of audio tapes have been coming thick and fast over the past 20 years. When the first CDs came onto the market, it was easy to predict that the popular cassette tape was ready for the dumpster. Now, some 20 years later, the cassette tape is still being produced in solid numbers. Sure, the music market for the magnetic tape is pretty much gone, but other markets, such as spoken language tapes, continue to see strong sales. Simple and Durable KISS applies well to the cassette Read More
