transfer rate
speed at which data can be transferred expressed in kilo bytes per second (Kbps) or bytes per second (Bps).
transfer stencil
refer to indirect stencil.

 


Transfer Rate
The rate at which data can be transferred, usually expressed as Kilobits per second (Kbps) or bytes per second (Bps).
Transmittance
The fraction of the light that passes through an object.

Transfer Rate
This is the speed your camera's memory card writes, or transfers, data or information about a picture from the camera. Some memory cards, such as those from Security Data, transfer as fast as 6MB/second.

A transfer rate of 1 Megabit per second (Mbps) equals 128 Kilobytes per second (KB/s) and is able to transfer 7.5 Megabytes of information per minute or about four 5 megapixel JPEG images.

Slightly faster transfer rates than standard CompactFlash cards.
More erase/write cycles possible than with flash memory ...

5in hard disk drive offers maximum storage and the fastest data transfer rates in RAID 0 whilecontinuous data storage is mirroredin RAID 1.

A very fast external bus standard that supports data transfer rates of up to 400 Mbps (400 million bits per second). Products supporting the 1394 standard go under different names, depending on the company.

These cards have a data transfer rate of up to 40 MB/s, which is twice that of the extreme III cards (see below). There are available in 2GB ($89.99), 4GB ($149.95) and 8GB ($299) versions.

The USB standard supports data transfer rates of 12Mbps (million bits per second), a vast improvement over the serial port standard it is beginning to replace.

If you buy a memory card that advertises a transfer rate of 4MB per second, and your camera only transfers photos at 2MB per second, you have just wasted your money because images can only be transfered at 2MB per second.

UDMA is a protocol developed by Quantum Corporation in conjunction with Intel that supports burst mode data transfer rates. UDMA rated memory cards are rated faster than non-UDMA memory cards. Find out more.

A new external bus standard that supports data transfer rates of 12Mbps. USB is expected to completely replace serial and parallel ports.

Current champs include the 100 MB/s transfer rate of Hoodman's RAW 16 GB CF card and 90 MB/s with SanDisk's Extreme Pro CF cards and Lexar's Professional 32 GB series.

What does this mean? This refers to the speed of the data transfer rate, where 1X=150 kilobytes per second. The higher the speed rating, the faster the camera will be able to write images to the memory card.

In order to spin their platters, microdrives also use up more battery power to operate than do compact flash cards. They also tend to have slower transfer rates since they have mechanical moving parts inside them.

What is the transfer rate and how long does it take to transfer images from a card to the device?
Can it display images on a TV set or be connected directly to a printer?
Can you view stored images on the device's own screen?

We use the same rating system used by the CD-ROM industry, where data transfer rate of 1x equals 150 kilobytes (KB) per second. The higher the speed rating, the faster your camera will be able to write images to the memory card.

A SPAPQ made by Syquest is a removable 16b hard-drive; spare discs are relatively cheap and the internal model of drive has a fast data transfer rate. Handy for storing many images that are being worked, manipulated or just waiting to be printed.

Designed to replace serial and parallel port connections. Data transfer rate is slow at only 12Mbits/sec. Plug and Play design. Devices can be connected and disconnected without re-starting the computer.

Devices such as the LaCie Bigger Disk Extreme feature capacities ranging from one to two terabytes. It includes both FireWire 400 and FireWire 800 interfaces, the latter of which uses a data transfer rate of up to 88 MB/sec. That's smoking! ...

Until recently that all cards faster then 6MB/s were class 6, so, for example, the Sandisk Extreme III cards with data transfer rates up to 30MB/s are still marked as class 6. Class 4 cards are 4MB/s and class 2 cards are 2 MB/s.

USB2's 480Mb/s rating is a lie, and refers only to its burst rate. You can get 400Mb/s over FW, but you can't get 480Mb/s transferring files via USB. Even if you found a USB2 - FW converter, you'd be hung up by the slow transfer rates of USB2.

Unlike the infrared data transfer method, which is also wireless, Bluetooth does not even require visual contact between the communications devices.
It operates on a frequency of 2.4 GHz and offers a regular transfer rate of 1 Mbit/s.
