The foundations of networking: switches, routers, and wireless access pointsSwitches, routers, and wireless access points are the essential networking basics. Through them, devices connected to your network can communicate with one another and with other networks, like the Internet. Switches, routers, and wireless access points perform very different functions in a network.By: rupaliWednesday, May 12, 2021EDUCATION

Drink enough waterIt’s common to get a little constipated if you don’t drink enough water. Inactivity, diet changes, illness, and even stress can add to the problem. Constipation usually passes on its own, but you can help move things along with exercise, over-the-counter meds, and of course, water. See a doctor if your constipation lasts for more than a week or two or you have dizziness, bad pain in your belly, or blood in your stool. These could be signs of something more serious.

Communication to Support Student Learning in a Digital Learning Environmenhttps://aap-uat.dokkuapps.venturit.org/knowledgenetwork/groups/knowledgenetwork/stories/1048 The P21 framework emphasizes effective use of oral, written, and nonverbal communication skills for multiple purposes (e.g., to inform, instruct, motivate, persuade, and share ideas). It also focuses on effective listening, using technology to communicate, and being able to evaluate the effectiveness of communication efforts—all within diverse contexts (adapted from P21). Note that working in partners is a great way to collaborate or build shared understanding but a critical part of communication is sharing with an authentic audience.By: Abira GroozWednesday, May 12, 2021CULTURE AND SOCIETY

symmetric-key encryptionsymmetric-key encryption is effective only if the symmetric key is kept secret by the two parties involved. If anyone else discovers the key, it affects both confidentiality and authentication. A person with an unauthorized symmetric key not only can decrypt messages sent with that key, but can encrypt new messages and send them as if they came from one of the two parties who were originally using the key.By: Vijaya Super adminWednesday, May 12, 2021AGRI-FOOD SYSTEMS+3

Note that working in partners is a great way to collaborate or build shared understanding but a critical part of communication is sharing with an authentic audience. Example strategies that use technology to support communication in the classroom: Host a TED-style conference or showcases for your students to present original ideas on a topic of interest to them to an authentic, external audience. Record and post the videos to a youtube stream. Provide opportunities to listen and ask questions through back channel tools like Today’s Meet or even Twitter. Have your students publish their work through blogs, by creating websites, and by building other online resources that are shared with authentic audiences.By: Rose HozwWednesday, May 12, 2021CULTURE AND SOCIETY+1

Encryption and decryptionEncryption and decryption address the problem of eavesdropping, one of the three Internet security issues mentioned at the beginning of this document. But encryption and decryption, by themselves, do not address another problem: tampering. This section describes how public-key cryptography addresses the problem of tampering. Tamper detection and related authentication techniques rely on a mathematical function called a one-way hash (also called a message digest). A one-way hash is a number of fixed length with the following characteristics: The value of the hash is unique for the hashed data. Any change in the data, even deleting or altering a single character, results in a different value. The content of the hashed data cannot, for all practical purposes, be deduced from the hash-which is why it is called "one-way."By: rupaliWednesday, May 12, 2021WATER, ENERGY, AND THE ENVIRONMENT+1
