• We fall ill because we live in an area with polluted surroundings or lack of personal hygiene.

• It is very important to adopt certain strategies to stay healthy and prevent diseases.

• One should remain active by exercising daily.

Principles of Adapted Physical Education :

1. Students with disabilities require adapted physical education activities to the limit of their capacity, to meet their physical, mental, social and emotional needs.
2. Every effort should be made to ensure that the adapted physical education programme is according to the needs and capacities of students.
3. The equipment, facilities, rules and instructions of an adapted physical education programme should be modified according to the need.
4. The adapted physical education programme should be physically as well as psychologically sound.
5. The teacher of physical education should note the anomalies, but should not try to treat the anomalies that need the attention of a medical specialist.
6. The activities of adapted physical education should be decided after close coordination with medical staff.

“The phenomenon of ejection of electrons from the surface of a metal when light of suitable frequency strikes on it, is called photoelectric effect.
The emitted electrons are called photoelectrons.”

Material culture refers to the physical objects, resources, and spaces that people use to define their lives. These include homes, neighborhoods, cities, schools, churches, synagogues, temples, mosques, offices, factories and plants, tools, means of production, goods and products, stores, and so forth. All of these physical aspects of a being help to define its members' behaviors and perceptions.

Non‐material culture refers to the nonphysical ideas that people have about their culture and within their lives, including beliefs, values, rules, norms, morals, language, organizations, and institutions. For instance, the non‐material cultural concept of religion/faiths consists of a set of ideas and beliefs about God, worship, morals, and ethics. These beliefs, then, determine how the culture responds to its religious topics, issues, and events.

"Evaluation is the collection of, analysis and interpretation of information about any aspect of a programme of education or training as part of a recognised process of judging its effectiveness, its efficiency and any other outcomes it may have." The Purpose of Evaluation and Testing

Tests tell the teacher about the effectiveness of his/her teaching. The basic purpose of an evaluation is to make a judgment about the quality or worth of an educational program, or proficiency of a student's attainments.

Everyone has the right to freedom of expression. This right shall include freedom to hold opinions and to receive and impart information and ideas without interference by public authority and regardless of frontiers.

Freedom of speech[2] is a principle that supports the freedom of an individual or a community to articulate their opinions and ideas without fear of retaliation, censorship, or legal sanction. The term "freedom of expression" is sometimes used synonymously but includes any act of seeking, receiving, and imparting information or ideas, regardless of the medium used.

Freedom of expression is recognized as a human right under article 19 of the Universal Declaration of Human Rights (UDHR) and recognized in international human rights law in the International Covenant on Civil and Political Rights (ICCPR). Article 19 of the UDHR states that "everyone shall have the right to hold opinions without interference" and "everyone shall have the right to freedom of expression; this right shall include freedom to seek, receive and impart information and ideas of all kinds, regardless of frontiers, either orally, in writing or in print, in the form of art, or through any other media of his choice". The version of Article 19 in the ICCPR later amends this by stating that the exercise of these rights carries "special duties and responsibilities" and may "therefore be subject to certain restrictions" when necessary "[f]or respect of the rights or reputation of others" or or the protection of national security or of public order (order public), or of public health or morals".

1. Privacy Concerns: 90 percent of devices collected at least one piece of personal information via the device, the cloud or the device’s mobile application. The vast majority of devices collecting information like name, address, date of birth or even health and credit card information. Even worse is the fact that many devices transmit this information across networks without encryption. If users misconfigure their home network, then they are only one step away from exposing this data through wireless networks. Cloud services, which many of these devices use, are also extremely vulnerable. However, it is likely that the majority of these devices actually need personal information to function.

2. Insufficient Authentication/Authorization: 80 percent failed to require passwords of sufficient complexity and length. A huge number of users and devices rely on weak and simple passwords and authorizations. Citing examples of this, HP found that many devices and their cloud components accepted passwords like “1234” or “123456”. Many users that configured accounts with weak passwords also used the same password in the cloud for cloud products. HP points out that a strong

password policy is basic security, but even still most solutions failed.

3. Transport Encryption: 70 percent of devices used unencrypted network services. Transport encryption is where information that is being transferred from one device to another device is encrypted from the outset of any communication. Transport encryption will be crucial given that most of the devices are transmitting data that most people would consider crucial. However, most devices surveyed failed to encrypt data, even when the devices were using the Internet. HP noted that the need for encryption is particularly strong given the amount of information that is being passed between the device, the cloud and mobile applications.

4. Web Interface: 60 percent raised security concerns with their user interfaces. These issues included:
persistent cross-site scripting, poor session management and weak default credentials. From this, hackers were able to identify valid user accounts and take them over using things like password reset features.

5. Insecure Software: 60 percent did not use encryption when downloading software updates. Given the number of software updates that will be required to make everything work together, HP says that it was “alarming” to find that so little of this software was encrypted during downloads. Even worse, some of the downloads that were tested could be intercepted and uploaded into a file system in Linux where the software could be seen or even modified.

Telnet is a protocol that allows you to connect to remote computers (called hosts) over a TCP/IP network (such as the internet). Using telnet client software on your computer, you can make a connection to a telnet server (that is, the remote host). A remote login facility permits a user who is using one computer to interact with a program on another computer. The Internet's remote login service is called TELNET. To use the service, one must invoke a local application program and specify a remote machine.

An electron can emit or absorb energy as radiations only in fixed amounts or bundles called quanta. This is known as quantisation of energy.
