Types of Digital Technology

• The introduction of digital technologies has replaced all technology dependent on physical analog, which were dominant before the 1970s. Digital technology has now changed global literacy, communication and the cultural development in societies. According to an 18-month study by the Science and Technology Council of the Academy of Motion Picture, Arts and Sciences, the reliability and storage of digital information goes beyond lost spreadsheets and snapshots.

Cameras

• Digital cameras function in the same way as traditional cameras but in a digital camera, images captured are stored in the digital memory located in a removable memory card. The total number of captured images that can be stored in this card depends on the quality, type of the image, capacity of memory and quality of the camera. This camera not only allows one to view captured images that have been stored in its memory but also to delete any unwanted images. Digital cameras also save data in such a way that it can be downloaded to a computer, a hard drive or even a portable storage device.

Computers

• Computers have evolved over the past few decades from the size of a room to laptop computers that can fit in a bag and can perform various tasks. The first digital computer was made in the late 1940s and it was able to process both numeric and symbolic values. Digital computers encode information and store it. They can encode symbols based on information being processed. Digital computers can also store information for longer periods compared with analog computers.

Televisions

• Digital television sets have been coded digitally. They are made in different shapes, sizes and designs that produce quality images and clear sound through high-resolution picture display. They offer multiple channel programming with the possibility of interactive video and data services. There are three types of digital television sets; Standard Definition (SDTV), Enhanced Definition (EDTV) and High Definition (HDTV). Analog television sets can also be made digital through the use of a converter box. A converter box is an electronic device that converts analog signals to digital, thus making it possible for one to view digital signals on the analog television set.

Digital Printing Equipment

• Digital printing is a direct printing application where the image is produced in a computer and sent directly to an output device. The ink delivery process is specific to each digital press, which makes it produce products of a high quality. They have the ability to produce low quantities at a reasonable price.
