Classification is a general process related to categorization, the process in which ideas and objects are recognized, differentiated, and understood. A classification system is an approach to accomplishing classification.
Classification systems are systems with a distribution of classes created according to common relations or affinities. Now-a-days Media is most important agent in defining or solving many political and social irregularities. So we should understand the basic terms and definitions of media to gain proper knowledge about media. The term ‘medias’ is incorrect one, and media is considered as a singular and plural word at the same time.
Simply media is an ‘agent’. It removes social irregularities and social evils. We live in a society which needs communication for better arrangements. For communication we find out equipments for better communication. Mass communication is a word which has a large in depth meaning in the media
terms. we can explore through simple technical study of media technology.

Media is a term referring to those organized means of dissemination of fact, opinion, entertainment, and other information such as newspapers, magazines, films, radio, television, internet, books, Cd’s, DVDs, and all other forms of publishing.
There are different ways to classify media.
1. Print media, non-print media, electronic media
• Print media. They include: books, journals, magazines, newspapers, workbook, textbooks
• Non-print media: they include: projected and non-projected media
• Electronic media: they include: Audio media, Visual media and Audio-Visual
2. Projected media & non-projected media
• Projected media: they require light source for projection. E.g. film projector slides etc.
• Non-projected media: they do not require light source. They include 3dimensional objects, 2dimensional objects, prints, charts, models etc.
3. Audio media, Visual media & Audio-visual
• Audio media: this form of media carry sounds alone. E.g. audio tapes, record player,
• Visual media: These are the ones that can be seen. E.g. TV, computer, white board
• Audio-Visual: this term refers to those instructional materials which provide students with audio and visual experiences by appearing to the hearing and seeing senses at the same time. E.g. TV, video tapes, closed circuit television (CCTV).
4. Hardware and software
• Hardware: this the classification of machines or equipment used in the instructional process. It is upon these gadgets that the software is transmitted. E.g. Television set, tape recorder etc.
• Software: this classification consists of all materials used with the machine. They are the real carrier of knowledge or information. They include, films, tapes transparencies.


The classification system itself must include an element of centralised control so that data may be classified in the context of overall strategic business objectives, such as compliance.
Secondly, before attempting to design a new classification system, it is important to check that the data sets to be classified and fed into the system are of good quality.
“A common problem with current information systems is that too much rubbish is allowed to accumulate, from duplication to copies of office party photos and personal letters to bank managers, making the task difficult, at best,” says Hale.
Storage cleansing products are useful here, because they remove redundant, obsolete or trivial content.
The third step is to carry out an information audit, to gain an accurate view of the nature of the data, including the dominant themes, semantics or the gist of the information, and not just the metadata.
The results of an audit then need to be placed in context with the existing metadata information, as well as the details of where and how the information has been stored, to give the richest possible view of the content. Audit presentation technology can help here, assisting classification designers to query, sift and filter audit results rapidly.
The last stage of the data classification and identification strategy is the classification design stage. Hale recommends that users combine classification design tools with audit presentation, which means that the audit results can be acted on: this ensures the system is more effective.
Hale urges IT managers to look at technology which use the audit themes and metadata to build a scheme, and then test that scheme against selected data sets to determine how successful the resulting classification will be.

Users should then be prepared to monitor and maintain the data classification system. “Once a classification scheme is up and running, it must not be considered to be set in stone – a process for review and update, again involving users, is required to ensure that adoption grows and that it continues to meet the changing needs of the organisation,” said Hale.

Classification of Media

The various types of Mass media are the following

1. Television
2. Radio
3. Print
4. Electronic
1. Television

Television first came to India named as Doordarshan on 1959. The first telecast started on 1959 in New Delhi. After a gap of 13 years, a second television station was established in Mumbai in 1972. The Ramayana and mahabharatha were the first programmes telecasted through Doordashan.In 1992 government liberated the brodcasting rules and many private channels came. Asianet communication limited was the first private cable channel in kerala. Now there are hunderds of channels in the cable network like Soorya, We tv, kairali, DD Malayalam, Manorama,India vision, Asianet Plus, Amrita, Jai Hind, reporter, ACV etc. Live
telecasting using OB Van became a new trend in Kerala to repot important issues. Zee Tv was the first private owned Indian channel to broadcast over cable. Now the LCD Television Sets came into the Market. It offer more clarity in the video and audio.

Content of the channels

Public Television in India has some social objectives like national integration, preservation of ecological balance,stimulation of agricultural activities, and also to promote interest in sports and games.

Radio Broadcasting began in India with the formation of a private radio service in Madras in 1936, the Indian broadcasting unit had been renamed as All India Radio(AIR). National Integration was the aim of the AIR after Independence.There are AM, SW, MW, FM type of broadcasting. FM broadcasting introduced in Madras in1977 and later in Jalandhar in 1992 and now common in kerala like Radio Mango, Club FM etc.
3. Newspapers

The first Newspaper in India is the Bengal gazette , later renamed as Hicky’s gazette. The first Newspaper in Kerala was the Rajyasamacharam published from Thalassery.Now there are Malayala manorama, Mathrbhumi, mangalam, Deshabhimani,
keralakoumudi, Madhyamam,Deepika, Veekshanam, metro vartha etc.

Electronic media means the media which can be operated by electricity, but in large sense,is the electronically transferred data. Internet, Email, Fax,Mobile are some examples. This is considered as the era of electronic media, such as internet.

Social Network is the one of the best utilities of the internet. Description of Mass Media here is concluding, because it is a vast subject like sea. It never ends. I would like to say that this is only a brief introduction of the subject. If you like to know more about the subject you can further study at journalism courses in kerala. This is an interesting subject also.
Classification system and classify information are material that a government body claims is sensitive information that requires protection of confidentiality, integrity, or availability. Access is restricted by law or regulation to particular groups of people, and mishandling can incur criminal penalties and loss of respect. A formal security clearance is often required to handle classified documents or access classified data. The clearance process usually requires a satisfactory background investigation. Documents and other information assets are typically marked with one of several (hierarchical) levels of sensitivity—e.g. restricted, confidential, secret and top secret. The choice of level is often based on an impact assessment; governments often have their own set of rules which include the levels, rules on determining the level for an information asset, and rules on how to protect information classified at each level. This often includes security clearances for personnel handling the information. Although “classified information” refers to the formal categorization and marking of material by level of sensitivity, it has also developed a sense synonymous with “censored” in US English. A distinction is often made between formal security classification and privacy markings such as “commercial in confidence”. Classifications can be used with additional keywords that give more detailed instructions on how data should be used or protected.
Some corporations and non-government organizations also assign sensitive information to multiple levels of protection, either from a desire to protect trade secrets, or because of laws and regulations governing various matters such as personal privacy, sealed legal proceedings and the timing of financial information releases.
The purpose of classification is to protect information. Higher classifications protect information that might endanger national security. Classification formalises what constitutes a “state secret” and accords different levels of protection based on the expected damage the information might cause in the wrong hands.
However, classified information is frequently “leaked” to reporters by officials for political purposes. Several U.S. presidents have leaked sensitive information to get their point across to the public
Typical classification levels
Although the classification systems vary from country to country, most have levels corresponding to the following British definitions (from the highest level to lowest)
Top secret (TS)

KGB traitors list seen in Museum of Genocide Victims Vilnius: originally marked top secret
Top secret is the highest level of classified information. Information is further compartmented so that specific access using a code word after top secret is a legal way to hide collective and important information. Such material would cause “exceptionally grave damage” to national security if made publicly available. Prior to 1942, the UK and other members of the British Empire used Most Secret, but this was changed to match the US’s Top Secret to simplify Allied interoperability.
The Washington Post reports in an investigation entitled Top Secret America, that per 2010 “An estimated 854,000 people … hold top-secret security clearances” in the United States.
“It is desired that no document be released which refers to experiments with humans and might have adverse effect on public opinion or result in legal suits. Documents covering such work field should be classified ‘secret’.”
April 17, 1947 Atomic Energy Commission memo from Colonel O.G. Haywood, Jr. to Dr. Fidler at the Oak Ridge Laboratory in Tennessee.[8] As of 2010, Executive Order 13526 bans classification of documents simply to “conceal violations of law, inefficiency, or administrative error” or “prevent embarrassment to a person, organization, or agency”.[9]
Secret material would cause “serious damage” to national security if it were publicly available.[10]
In the United States, operational “Secret” information can be marked with an additional “LIMDIS”, to limit readership.
Confidential material would cause damage or be prejudicial to national security if publicly available.[11]
Restricted material would cause “undesirable effects” if publicly available.[11] Some countries do not have such a classification; in public sectors, such as commercial industries, such level are also called and known as “Private Information”.
Official material forms the generality of government business, public service delivery and commercial activity. This includes a diverse range of information, of varying sensitivities, and with differing consequences resulting from compromise or loss. OFFICIAL information must be secured against a threat model that is broadly similar to that faced by a large private company.
The OFFICIAL classification replaces the Confidential and Restricted classifications after April 2014 in the UK.[12]
Unclassified is technically not a classification level, but this is a feature of some classification schemes, used for government documents that do not merit a particular classification. This is because the information is low-impact, and therefore does not require any special protection, such as vetting of personnel.
A plethora of pseudo-classifications exist under this category.
Clearance is a general classification, that comprises a variety of rules controlling the level of permission required to view so classified information, and how it must be stored, transmitted, and destroyed. Additionally, access is restricted on a “need to know” basis. Simply possessing a clearance does not automatically authorize the individual to view all material classified at that level or below that level. The individual must present a legitimate “need to know” in addition to the proper level of clearance.
Compartmented information
In addition to the general risk-based classification levels, additional compartmented constraints on access exist, such as (in the U.S.) Special Intelligence (SI), which protects intelligence sources and methods, No Foreign dissemination (NOFORN), which restricts dissemination to U.S. nationals, and Originator Controlled dissemination (ORCON), which ensures that the originator can track possessors of the information. Information in these compartments is usually marked with specific keywords in addition to the classification level.
Government information about nuclear weapons often has an additional marking to show it contains such information (CNWDI).
When a government agency or group shares information between an agency or group of other country’s government they will generally employ a special classification scheme that both parties have previously agreed to honour.
For example, the marking ATOMAL, is applied to U.S. RESTRICTED DATA or FORMERLY RESTRICTED DATA and United Kingdom ATOMIC information that has been released to NATO. ATOMAL information is marked COSMIC TOP SECRET ATOMAL (CTSA), NATO SECRET ATOMAL (NSAT), or NATO CONFIDENTIAL ATOMAL (NCA).
Private corporations often require written confidentiality agreements and conduct background checks on candidates for sensitive positions.[35] In the U.S. the Employee Polygraph Protection Act prohibits private employers from requiring lie detector tests, but there are a few exceptions. Policies dictating methods for marking and safeguarding company-sensitive information (e.g. “IBM Confidential”) are common and some companies have more than one level. Such information is protected under trade secret laws. New product development teams are often sequestered and forbidden to share information about their efforts with un-cleared fellow employees, the original Apple Macintosh project being a famous example. Other activities, such as mergers and financial report preparation generally involve similar restrictions. However, corporate security generally lacks the elaborate hierarchical clearance and sensitivity structures and the harsh criminal sanctions that give government classification systems their particular tone.

Classification systems are systems with a distribution of classes created according to common relations or affinities. Now-a-days Media is most important agent in defining or solving many political and social irregularities.
