  • symmetric-key encryption
    symmetric-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.

  • Communication to Support Student Learning in a Digital Learning Environment
    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. 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.

  • Encryption and decryption
    Encryption 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."

  • symmetric-key encryption
    With symmetric-key encryption, the encryption key can be calculated from the decryption key and vice versa. With most symmetric algorithms, the same key is used for both encryption and decryption.Implementations of symmetric-key encryption can be highly efficient so that users do not experience any significant time delay as a result of the encryption and decryption. Symmetric-key encryption also provides a degree of authentication, since information encrypted with one symmetric key cannot be decrypted with any other symmetric key. Thus, as long as the symmetric key is kept secret by the two parties using it to encrypt communications, each party can be sure that it is communicating with the other as long as the decrypted messages continue to make sense.

  • How does cloud computing work
    You also have to purchase software as well as software licenses and then provide these softwares to your employees as they require. Whenever you hire a new employee, you need to buy more software or make sure your current software license allows another user. It is so stressful that you have to spend lots of money. But, there may be an alternative for executives like you. So, instead of installing a suite of software for each computer, you just need to load one application. That application will allow the employees to log-in into a Web-based service which hosts all the programs for the user that is required for his/her job. Remote servers owned by another company and that will run everything from e-mail to word processing to complex data analysis programs. It is called cloud computing, and it could change the entire computer industry.

  • Search engine optimisation 
    Search engine optimization (SEO) is the process of improving the quality and quantity of website traffic to a website or a web page from search engines. SEO targets unpaid traffic (known as "natural" or "organic" results) rather than direct traffic or paid traffic. Unpaid traffic may originate from different kinds of searches, including image search, video search, academic search, news search, and industry-specific vertical search engines.

  • Computer Input and Output Devices
    Computer being a versatile machine can process different types of data. so to work with these data types we need different type of devices which can help us to enter such data types in the computer and to receive their outputs as well in this chapter we will cover many such devices like keyboard, mouse, joystick, light pen, printer, speaker, etc. That can be used with the computer. What is computer?Children you know that computer is a data processing machine and it needs user’s instructions to perform any job. After processing the raw facts (called data), it produces useful information for the user. But how do you give data and instructions to the computer and how it can return the useful information to you.To do all these, different types of input and output devices can be connected with the computer.Input DevicesThe devices which are used to give data and instructions to the computer are called Input Devices. Various types of input devices can be used with the computer depending upon the type of data you want to enter in the computer, e.g., keyboard, mouse, joystick, light pen, etc.Output DevicesThe devices which are used to display the results or information are called Output Devices. You can view the output on the monitor or you can print it on a paper using a printer. Monitor and the printer are the commonly used output devices.
