WEEK 2                                                                 TOPIC: information processing 

CONTENT

Information processing

 

Information processing is the acquisition, recording, organization, retrieval, display and dissemination of information.

Information processing could also be referred to as the manipulation of digitalized information by computers and other digital electronic equipment, known collectively as Information technology.

A computer information processor processes information to produce understandable results. For example, an information processor works to translate and format the digital information for printed form. 

 

Collation of Information

 

Collation is the assembly of written information into a standard order. Many systems of collation are based on numerical order or alphabetical order, or extensions and combinations thereof. Collation is a fundamental element of most office filing systems, library catalogs, and reference books.

The main advantage of collation is that it makes it fast and easy for a user to find an element in the list, or to confirm that it is absent from the list. In automatic systems this can be done using a binary search algorithm or interpolation search; manual searching may be performed using a roughly similar procedure, though this will often be done unconsciously. Other advantages are that one can easily find the first or last elements on the list (most likely to be useful in the case of numerically sorted data), or elements in a given range (useful again in the case of numerical data, and also with alphabetically ordered data when one may be sure of only the first few letters of the sought item or items).

Information organization

 

Information organization (IO) is defined in this literature review as the process of ordering, surrogation, or description information and information objects. These three tasks have been identified by the author as broad tasks that both identify tangible elements of IO and have implications across areas of information research including retrieval, interaction, and personal information management.

Analysis of Information

Information analysis is the science of evaluating information content, and refining information to build portfolios. Information analysis works both for managers who use a non-quantitative process and for those who use a quantitative investment process. The only requirement is that there is a process./

Information is a fuzzy concept. Information analysis begins by transforming information into something concrete: investment portfolios. Then it analyzes the performance of those portfolios to determine the value of the information.

Information analysis can work with something as simple as an analyst’s buy and sell recommendations. Or it can work with alpha forecasts for a broad universe of stocks. Information analysis is not concerned with the intuition or process used to generate stock recommendation only with the recommendations themselves.

 

Information Interpretation

Information interpretation is the process through which organizations make sense of new information that they have acquired and disseminated.

Chart

A chart, also called a graph, is a graphical representation of data, in which "the data is represented by symbols, such as bars in a bar chart, lines in a line chart, or slices in a pie chart".[1] A chart can represent tabular numeric data, functions or some kinds of qualitative structure and provides different info.

The term "chart" as a graphical representation of data has multiple meanings:

Charts are often used to ease understanding of large quantities of data and the relationships between parts of the data. Charts can usually be read more quickly than the raw data that they are produced from. They are used in a wide variety of fields, and can be created by hand (often on graph paper) or by computer using a charting application. Certain types of charts are more useful for presenting a given data set than others. For example, data that presents percentages in different groups (such as "satisfied, not satisfied, unsure") are often displayed in a pie chart, but may be more easily understood when presented in a horizontal bar chart.[2] On the other hand, data that represents numbers that change over a period of time (such as "annual revenue from 1990 to 2000") might be best shown as a line chart.

Mobile Phone

Definition - What does Mobile Phone mean?

A mobile phone is a wireless handheld device that allows users to make calls and send text messages, among other features. The earliest generation of mobile phones could only make and receive calls. Today’s mobile phones, however, are packed with many additional features, such as Web browsers, games, cameras, video players and even navigational systems.

A mobile phone may also be known as a cellular phone or simply cellphone.

Mobile Phone

When the first mobile phones were introduced, their only function was to make calls, and they were so bulky it was impossible to carry them in a pocket.

Later, mobile phones belonging to the Global System for Mobile Communications (GSM) network were capable of sending and receiving text messages. As these devices evolved, they became smaller and more features were added, such as multimedia messaging service (MMS), which allowed users to send and receive images.

Most of these MMS-capable devices were naturally equipped with cameras, which allowed users to capture photos with the built-in camera, add captions, and send them to friends and relatives who also had MMS-capable phones.
 Data processing SS1 second term lesson note
A mobile phone with highly advanced features is called a smartphone, while a regular mobile phone is known as a feature phone.
Data processing SS1 second term lesson note
A mobile phone typically operates on a cellular network, which is composed of cell sites scattered throughout cities, countrysides, and even mountainous regions. If a user happens to be located in an area where there is no signal from any cell site belonging to the cellular network provider he or she is subscribed to, calls cannot be placed or received in that location.

NEWSPAPER
