Input Device is a hardware part of the computer that is used to enter data and instructions into computer memory.
Information is represented as a picture Acoustic encoding: Information is represented as sounds Semantic encoding: This means that you take in information, either as a picture, a sound, or give the information meaning. For example, if you look at a telephone number on a piece of paper, you are using visual encoding.
If you say the number out loud, you are acoustically encoding. If you notice that some of the digits sequentially represent a special date, you give that number meaning and thus semantically encoding.
Storage Storage is the retention of information over time. It is believed that we can accumulate information in three main storage areas: Information is stored sequentially in the three memory systems, and the storage areas vary according to time frames.
The period of time that information is retained is anywhere from a fraction of a second to years. Sensory memory only stores information for a brief second. Short-term memory can hold information longer, but it is only usually about seconds. Long-term memory, however, can last a lifetime.
Sensory Memory Sensory memory stores incoming sensory information in detail, but only for a fraction of a second. The capacity of sensory memory is very large, but the information in it is unprocessed. Short-Term Memory Some of the information in sensory memory transfers to short-term memory.
Short-term memory can hold information for approximately seconds. Rehearsing the information can help keep it in short-term memory longer. Short-term memory has a limited capacity.
It is believed to hold about seven pieces of information, plus or minus two pieces. Chunking is a method that can help increase the capacity of short-term memory. Chunking involves grouping small bits of information into larger chunks.
Long-Term Memory Long-term memory has an almost an unlimited storage capacity. Information that makes it into long-term memory can remain there for your entire life.
However, even though it is there you may not always be able to remember the information, because you may not be able to retrieve it.
The way we store information in long-term memory affects the way we retrieve it.INPUT DEVICES Input devices are used to enter data and instructions into computer memory from external world. Input Device is a hardware part of the computer that is used to enter data and instructions into computer memory.
A computer storage device is any type of hardware that stores data. The most common type of storage device, which nearly all computers have, is a hard drive. The computer's primary hard drive stores the operating system, applications, and files and folders for users of the computer.
A component or peripheral device (such as a barcode reader, graphic tablet, keyboard, magnetic-stripe reader, modem, mouse, scanner, or stylus) that feeds data or instruction into a computer for display, processing, storage, or outputting or transmission..
Input devices convert the user's actions and analog data (sound, graphics, pictures) into digital electronic signals that can be processed. Online data storage refers to the practice of storing electronic data with a third party service accessed via the Internet. It is an alternative to traditional local storage (such as disk or tape drives) and portable storage (such as optical media or flash drives).
It can also be called "hosted. The flat-panel display refers to a class of video devices that have reduced volume, weight and power requirement in comparison to the CRT.
You can hang them on walls or wear them on your wrists. Current uses of flat-panel displays include calculators, video games, . Components of a Computer System - Input, Process, Output. Conventional and assistive computer technologies are similar in that both employ the core concepts of input, information processing, and output (ATA, ).
Understanding these concepts is essential to understanding how AT helps individuals with disabilities access a computer.
