what is PGP in Hindi pretty good privacy?

PGP

इसका Full नाम pretty good privacy है। यह एक encryption तथा decryption Computer program है जो कि इंटरनेट में Email messages को encrypt तथा decrypt करने के लिए use में लाया जाता है।

PGP, public key cryptography की विधि पर आधारित है। इसमें दो keys का use किया जाता है। message को encrypt करने वाली key को public के लिए रखा जाता है और message को decrypt करने वाली key को secret रखा जाता है।

extra notes is hindi:-

PGP public key प्रणाली की एक भिन्नता का उपयोग करता है। इस प्रणाली में, प्रत्येक उपयोगकर्ता के पास एक encryption key है जो सार्वजनिक रूप से ज्ञात है और एक private key है जो केवल उस उपयोगकर्ता के लिए जानी जाती है। आप एक message encrypt करते हैं जिसे आप किसी और को भेजते हैं। जब वे इसे प्राप्त करते हैं, तो वे इसे अपनी private key का उपयोग करके decrypt करते हैं। चूँकि संपूर्ण message को एन्क्रिप्ट करना समय लेने वाला हो सकता है, PGP संदेश को एन्क्रिप्ट करने के लिए तेज़ encryption algorithm का उपयोग करता है और फिर public key का उपयोग करके उस small key को एन्क्रिप्ट करता है जिसका उपयोग संपूर्ण संदेश को encrypt करने के लिए किया गया था। encrypt किए गए संदेश और छोटी कुंजी दोनों को रिसीवर को भेजा जाता है, जो पहले small key को decrypt करने के लिए रिसीवर की निजी कुंजी का उपयोग करता है और फिर संदेश को decrypt करने के लिए उस कुंजी का उपयोग करता

PGP In English :

PGP uses a variation of the public key system. In this system, each user has an encryption key that is publicly known and is a private key that is known only for that user. You encrypt a message that you send to someone else. When they receive it, they decrypt it using its own private key. Because encrypting the entire message can be time-consuming, PGP uses the fast encryption algorithm to encrypt the message and then encrypts the small key using the public key that is used to encrypt the entire message it was done. Both encrypted messages and small keys are sent to the receiver, which first uses the receiver's private key to decrypt a small key and then uses that key to decrypt the message.

Network Components

Basic computer network components

Networking

Network Interface Card - . NIC prepares (draft) and sends. Receives data, data, and controls data flows between computers and networks. On the dispatching side, NIC passes the frame of data on the physical layer, which transmits the data on the physical link. On behalf of the receiver, NIC processes the bits obtained from the physical layer and processes the message based on its content.

Early network interface controllers were usually applied to extended cards that were plugged into a computer bus. Lower cost of Ethernet standard and ubiquity means that most newer computers have a built-in network interface in the motherboard.

Hub -Hub is a type of device that divides the networks. Connect to many computers. This is like a distribution center. When a computer requests information from a network or a specific computer, it sends a request to the hub via cable. The hub will receive the request and will transmit it to the entire network. Every computer in the network should then find out whether the broadcast data is for them or not.

"A network hub is a node that transmits data from every computer or ethernet-based device. A hub switch is less refined, after which different devices can separate data transmission."

Switch - Switch is a type of telecommunication tool that is grouped as one of the computer network components. The switch is like a hub but is built with advanced features. It uses the physical device address in each incoming message so that it can deliver messages to the right destination or port.

Like a hub, the switch does not broadcast the received message across the network, but before checking for which system or port the message should be sent. In other words, the switch directly connects the source and destination, which increases the speed of the network. Common features in both switches and hubs are: multiple RJ-45 ports, power supply and connection lights.
