Encryption works by using keys to scramble data before transmitting it, then using the same key to unscramble it upon receipt. There are two main types: symmetric key encryption which uses the same key by both parties, and public key encryption which uses different keys but relates them through hashing. Public key encryption addressed weaknesses in symmetric key encryption by allowing secure communication without pre-sharing a key. Hashing algorithms are used to generate hash values from data in public key encryption in a way that makes deriving the original data nearly impossible without the hash value.
The document summarizes a trip to China, including a 24-hour flight, staying in a hotel with a pool on the 3rd floor, visiting an Olympic village and stadium where the author ran 400 meters, learning about silk at the Silk Market, seeing temples used to worship Buddha that emperors would vacation at, and seeing parts of the Great Wall that were destroyed.
This document promotes an unhealthy pursuit of perfection through extreme weight loss and control over eating, suggesting that readers can achieve their dreams of being perfect by keeping calm, stopping eating, and enjoying the process. It acknowledges that this lifestyle will never be enough but claims that the feeling of being skinny is better than any food.
Amazon employs various technologies to securely process online orders and payments. Its massive data warehouse contains over 15 terabytes of customer data and handles millions of daily operations for both Amazon's direct sales and sales through third-party sellers. In addition to selling goods directly from its own warehouses, Amazon allows other large retailers to use its platform for online sales fulfillment. Through marketing partnerships, product recommendations, and community websites, Amazon aims to be the most customer-centric online retailer.

Fiber optics use thin strands of glass called optical fibers to transmit light signals over long distances. An optical fiber consists of a core surrounded by cladding that reflects light internally through total internal reflection. Hundreds or thousands of fibers are bundled in cables. A fiber optic system includes a transmitter that encodes light signals, the optical fiber that conducts the signals, and a receiver that decodes the signals. Fiber optics offer advantages over copper wire including lower costs, higher data capacity, immunity to electromagnetic interference, lighter weight, and non-flammability.
This document provides a summary of the EU optical fiber market from 2007-2015, including key findings, trends, production, trade, prices and forecasts. It finds that in 2015, the EU market volume was *** thousand tonnes, an increase of ***% from 2014. The market value was *** million EUR in *** prices, ***% higher than 2014. Domestic production was *** thousand tonnes and *** million EUR, both up ***% from 2014. Imports were *** thousand tonnes and *** million EUR, increasing ***% and ***% respectively over 2014. Exports totaled *** thousand tonnes and *** million EUR, rising ***% and ***% from 2014 levels. The report includes analysis of trade balances
The following ppt gives overview about Optical Communication and the underlying principle with the general overview of all the contents for optical communication
An optical fiber is a glass or plastic fiber that carries light along its length. They are widely used in fiber-optic communications, which permits transmission over longer distances and at higher bandwidths (data rates) than other forms of communications. Fibers are used instead of metal wires because signals travel along them with less loss, and also immune to electromagnetic interference. Fibers are also used for illumination, and are wrapped in bundles to carry images. Specially designed fibers are used for other applications, including sensors and fiber lasers.
This document provides an overview of optical fibers, including their definition, main components, types, parameters, transmission properties, attenuation factors, dispersion effects, and applications. Optical fibers are thin strands of glass that transmit light signals over long distances using total internal reflection. They have a higher glass core surrounded by a lower index cladding. Key fiber types are single-mode and multimode (step-index and graded-index), which differ in core size and number of propagation modes. Parameters like acceptance angle, numerical aperture, and normalized frequency determine fiber properties and performance.
Fiber optics and how optical communication takes place.Details regarding how signalling,routing and switching occurs in optical network .A little detail about various equipments used in optical communication.
Optical fibers use total internal reflection to transmit light signals along their core. They have a higher refractive index core surrounded by a lower index cladding. Acceptance angle and modal/material dispersion affect signal transmission. Monomode fibers have a small single-path core to eliminate modal dispersion, while multimode fibers have a larger core allowing multiple light paths and more dispersion. Attenuation and noise also impact signal quality during fiber optic transmission.
The document discusses the Public Switched Telephone Network (PSTN) architecture and components. It describes how PSTN uses digital trunks between central office switches and analog lines from phones to the central office. It also discusses digitization of voice signals, the major components of PSTN including local loops, trunks, and switching offices.
This document provides information about lasers, including:
1. Lasers produce coherent light through stimulated emission of radiation.
2. Coherent light is uniform in frequency, amplitude, and phase, unlike incoherent light from other sources.
3. Key atomic interactions that enable laser action are induced absorption, spontaneous emission, and stimulated emission, which allows for population inversion and optical pumping to produce more atoms in the excited state.
Lasers emit light that is highly directional, monochromatic, and coherent. Common laser components include an active medium, excitation mechanism, and high and partially reflective mirrors. Lasing occurs when atoms in the active medium are excited and stimulated emission produces photons. Laser output is measured in watts, joules, irradiance, and pulsed vs. continuous wave. Laser hazards include eye, skin, chemical, electrical, and fire risks. Lasers are classified based on wavelength, average power, energy per pulse, and beam exposure to determine appropriate safety controls.

How to Make a Field Mandatory in Odoo 17Celine George
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.
A workshop hosted by the South African Journal of Science aimed at postgraduate students and early career researchers with little or no experience in writing and publishing journal articles.
