HashingIn terms of security, hashing is a technique used to encrypt data and generate unpredictable hash values. It is the hash function that generates the hash code, which helps to protect the security of transmission from unauthorized users. Hash function algorithms Hashing algorithm provides a way to verify that the message received is the same as the message sent. It can take a plain text message as input and then computes a value based on that message. Key Points The length of computed value is much shorter than the original message. It is possible that different plain text messages could generate the same value. Here we will discuss a sample hashing algorithm in which we will multiply the number of a’s, e’s and h’s in the message and will then add the number of o’s to this value. For example, the message is “ the combination to the safe is two, seven, thirty-five”. The hash of this message, using our simple hashing algorithm is as follows: The hash of this message is sent to John with cipher text. After he decrypts the message, he computes its hash value using the agreed upon hashing algorithm. If the hash value sent by Bob doesn’t match the hash value of decrypted message, John will know that the message has been altered.By: rupaliTuesday, May 18, 2021EDUCATION

CultureCulture is an umbrella term which encompasses the social behavior and norms found in human societies, as well as the knowledge, beliefs, arts, laws, customs, capabilities, and habits of the individuals in these groups. Humans acquire culture through the learning processes of enculturation and socialization, which is shown by the diversity of cultures across societies. Culture is a word for the 'way of life' of groups of people, meaning the way they do things. Different groups may have different cultures. A culture is passed on to the next generation by learning, whereas genetics are passed on by heredity. Culture is seen in people's writing, religion, music, clothes, cooking and in what they do.By: rupaliTuesday, May 18, 2021CULTURE AND SOCIETY+1

EncryptionEncryption: In cryptography, encryption is the process of encoding information. This process converts the original representation of the information, known as plaintext, into an alternative form known as ciphertext. Ideally, only authorized parties can decipher a ciphertext back to plaintext and access the original information. Encryption is a way of scrambling data so that only authorized parties can understand the information. In technical terms, it is the process of converting human-readable plaintext to incomprehensible text, also known as ciphertext. In simpler terms, encryption takes readable data and alters it so that it appears random.By: rupaliTuesday, May 18, 2021EDUCATION

Clear rules and advanced planning are keys to success for teachers of students with ADHD.Many students with ADHD have significant difficulties with organization. They are more likely to respond positively when teachers establish class routines and set procedures and maintain a well-organized learning environment. Clear rules and advanced planning are keys to success for teachers of students with ADHD. The following organizational supports are particularly useful. Students should be taught to use these tools through teacher modeling and guided practice with feedback before being expected to use them more independently. Assignment Notebook: Provide the student with an assignment notebook to helporganize homework and seatwork.Color-Coded Folders: Provide the student with color-coded folders to helporganize assignments for different academic subjects.Homework Partners: Assign the student a partner who can help recordBy: Anne miller chinthanaThursday, May 13, 2021CULTURE AND SOCIETY+1

Greenhouse effect: WarmingThe "greenhouse effect" is the warming that happens when certain gases in Earth's atmosphere trap heat. These gases let in light but keep heat from escaping, like the glass walls of a greenhouse, hence the name. Sunlight shines onto the Earth's surface, where the energy is absorbed and then radiate back into the atmosphere as heat. In the atmosphere, greenhouse gas molecules trap some of the heat, and the rest escapes into space. The more greenhouse gases concentrate in the atmosphere, the more heat gets locked up in the molecules.By: rupaliWednesday, May 12, 2021WATER, ENERGY, AND THE ENVIRONMENT+1

Global warmingGlobal warming is the long-term heating of Earth's climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere. Climate change includes both global warming driven by human-induced emissions of greenhouse gases and the resulting large-scale shifts in weather patternsBy: rupaliWednesday, May 12, 2021WATER, ENERGY, AND THE ENVIRONMENT+1
