3. 1. Collection of data- Capturing data from their sources and
recording it into some media (e.g. Paper).
2. Preparation of data- Copying, grouping, or arranging data in
a more convenient way for input.
3. Input of data- Entering the data or sending the stored data
into the processing system.
4. Processing of data- Calculating or manipulating the input
data and even storing the results for future use.
5.Output of Information- Giving out the processed results in a
readable form (e.g., a report).

4. Components of Information Processing

5. Sensory Register- Each sensory system has its own sensory store, which
receives and holds, although very briefly, all the external and internal
stimuli. The sensory stores hold onto the sensory information long enough
so that unconscious processes may operate on these traces to determine
whether the input should be brought into the working memory, or
discarded.
Short-Term/Working Memory- Working memory is believed to be the
centre of conscious thought, analogous to the “central processing unit” of a
computer, where information from long-term memory and the environment
is combined to help solve problems. However, the working memory has a
small capacity so that it is not able to attend to much information at a
time, thereby limiting the abilities of humans to solve problems. This faster
processing speed permits faster mental movement from one item of
information to another, which improves one’s ability to keep track of a
number of different items in working memory at once.

6. Long-Term Memory- Long-term memory is the stored representation of all
that a person knows. The items stored in long-term memory lie dormant until
they are called back into the working memory and thus put to use. Long-term
memory consists of explicit and implicit long-term memory systems.
