Many language teachers were already familiar with the concept of hypertext on stand-alone computers, which made it possible to set up non-sequential structured reading activities for language learners in which they could point to items of text or images on a page displayed on the computer screen and branch to any other pages, e.g. in a so ...
The ideal pixel density (PPI) depends on the output format, output device, the intended use and artistic choice. For inkjet printers measured in DPI it is generally good practice to use half or less than the DPI to determine the PPI. For example, an image intended for a printer capable of 600 dpi could be created at 300 ppi.

For example, a bitmap image may measure 1,000 × 1,000 pixels, a resolution of 1 megapixel. If it is labelled as 250 PPI, that is an instruction to the printer to print it at a size of 4 × 4 inches. Changing the PPI to 100 in an image editing program would tell the printer to print it at a size of 10 × 10 inches.
The Parallel Peripheral Interface (PPI) is a peripheral found on the Blackfin embedded processor. The PPI is a half-duplex , bi-directional port that is designed to connect directly to LCDs , CMOS sensors , CCDs , video encoders (video DACs ), video decoders (video ADCs ) or any generic high speed, parallel device.
Video of the process of scanning and real-time optical character recognition (OCR) with a portable scanner. Optical character recognition or optical character reader (OCR) is the electronic or mechanical conversion of images of typed, handwritten or printed text into machine-encoded text, whether from a scanned document, a photo of a document, a scene photo (for example the text on signs and ...
ICALL developed from the field of Computer Assisted Language Learning (CALL) in the late 1970s [1] and early 1980s. [5] ICALL is a smaller field, and not yet fully formed. Following the pattern of most language learning technologies, English is a prominent language featured in ICALL technology. [7]
