data tape

HP SDLT storage media is ideally suited for data centre and departmental backups where capacity, performance and cost are critical. SDLT technology offers up to 160 GB of storage capacity and a 16MB/sec sustained data transfer rate (native mode).2nd generation Super DLT II 600GB Data Cartridge offers high capacity and low cost per GB for customers with prior investments in DLT backup technology. Super DLTtape II cartridges support DLTSage for improved media and drive diagnostics. High-performance: up to 32MB/sec compressed transfer rate Comprehensive: read-backwards compatible with DLTtape High-capacity: supports capacities up to 320GB Reliable: combines the best of proven optical and magnetic technologies to offer users improvements in capacity and performance HP SDLT cleaning cartridges: provide 20 cleans With 600GB capacity and 72MB/sec transfer rate, HP SDLT II 600GB Data Cartridges offer high capacity and low cost per GB for customers with prior investments in DLT backup technology. Super DLTtape II uses a new Super PET (S-PET) base film enabling an overall thickness reduction of 10%. This results in a longer tape with more capacity versus a Super DLTtape I cartridge. Optical servo guide information is coded on the rear of the media, increasing the number of recording tracks on the data-bearing media surface. This enables higher capacity tape cartridges like Super DLT II.

VGA CABLE

A VGA connector (also RGB connector, D-sub15, mini sub D15, and mini D15 connector), is a three-row 15-pin DE-15 connector, of which there are four versions: (i) the original VGA15 pinout connector, (ii) DDC2 pinouts, (iii) the older, less flexible DE-9 connector, and (iv) the Mini-VGA used for laptop computers.

The 15-pin VGA connector is common to most video cards, computer monitors, and high definition television sets that support VGA-connector devices. It usually is known as an “HD-15” (High Density 15) or “DE-15”, distinguishing it from connectors of like form factor, but with only 2 rows of pins. Occasionally, this connector is incorrectly referred to as a “DB-15” or as an “HDB-15”.^{[citation needed]} VGA connectors and cables are used solely to carry analog componentRGBHV (red - green - blue - horizontal sync - vertical sync) video signals, a Display data channel (DDC2) digital clock, and data. When device size is a spatial constraint (i.e. laptop computers), a mini-VGA port occasionally is in place of the full-sized VGA connector.

BLUETOOTH

Bluetooth is an open wireless protocol for exchanging data over short distances (using short length radio waves) from fixed,PC and mobile devices, creating personal area networks(PANs). It was originally conceived as a wireless alternative to RS-232 data cables. It can connect several devices, overcoming problems of synchronization.

USB EXTENSION CABLE

Do you need to extend the distance from your computer to a USB device such as a printer or scanner? According to the USB specification, you can use passive extension cables (i.e., cables without an active repeater chip in them) for distances up to 16 feet. Beyond sixteen feet, you need a cable that will boost the signal in order to avoid losing data or, worse yet, damaging USB equipment.

The maximum distance that you can reach by chaining Active USB Extension Cables together is 80 feet. By using 16 foot cables (the most common length available) you can safely chain up to 4 of these together without risking data loss or damage to your device (in addition to the 4-active extension cables you will use a regular device cable at the end that can be up to 16 feet - this is how you achieve the maximum distance of 80 feet).
In order to use a USB Extension Cable with a device, you plug the extension cable directly into the USB port on your desktop or notebook. On the other end of the cable, you will have a type A female port where you can plug your device cable in, which will be connected to the device on the other end.

CARD READER

A memory card reader is a device used for communication with a smart card or a flash memory card. A business card reader is a scanning device used to scan and electronically save business cards. Amagnetic card reader is a device used to scan cards containing magnetic data strips. A punched card reader is a device used to read holes in punched cardboard cards.

video card

A video card, video adapter, graphics-accelerator card, display adapter or graphics card is an expansion card whose function is to generate and output images to a display. Many video cards offer added functions, such as accelerated rendering of 3D scenes and 2D graphics, video capture, TV-tuner adapter, MPEG-2 and MPEG-4 decoding, FireWire, light pen, TV output, or the ability to connect multiple monitors (multi-monitor), while other modern high performance cards are used for more graphically demanding purposes such as PC games.

Video hardware can be integrated on the motherboard, as it often happened with early computers; in this configuration it was sometimes referred to as a video controller or graphics controller.

WEBCAM

A webcam is a video capture device connected to a computer orcomputer network, often using a USB port or, if connected to a network, ethernet or Wi-Fi.

The most popular use is for video telephony, permitting a computer to act as a videophone or video conferencing station. This can be used in messenger programs such as Windows Live Messenger,Skype and Yahoo messenger services. Other popular uses, which include the recording of video files or even still-images, are accessible via numerous software programs, applications and devices.

Webcams are known for low manufacturing costs and flexibility.^[1]

The term "webcam" may also be used in its original sense of a video camera connected to Web continuously for an indefinite time, rather than for a particular session, generally supplying a view for anyone who visits its Web page. Some such webcams, for example those used as online traffic cameras, are expensive, rugged professional-grade hardware.
