MIDTERM EXAM ITEC 620- INFORMATION TECHNOLOGY INFRASTRUCTURE I. Information sources and representations (20 points) 1. (7 pts) What are the main issues and challenges to interpret audio as voice input and to translate the data into alphanumeric form? What is the current state of the technology and what issues need to be addressed? The technology must convert the voice data into groups of data known as phonemes. These phonemes, the smallest sound in a language, must then be placed in the appropriate order so the alphanumeric form is correct. One of the main issues being encountered by this technology is the understanding of sentence context. The technology must be able to overcome the challenge of words such as to, too, and two and even read and red. The technology must overcome this as well as various dialects and regional accents. Although this technology is still in its infancy most believe that the technology to interpret voice input to alphanumeric form will be seen in the near future. 2. (6 pts) Which of the following assumes the existence of a rectangular “screen” upon which is located one or more rectangular images of possibly different sizes? c) GIF GIF assumes the existence of a rectangular “screen” upon which is located one or more rectangular images of possibly different sizes. Areas not covered with images are painted with a background color. The format divides the picture information and data into a number of blocks, each of which describes aspects of the image. The first block, called the header block, identifies the file as a GIF file. Following the header block is a logical screen-descriptor block,
