Hello Friends .... Today we learn about the Data Encryption So let's Start..... A Definition of Data Encryption Data encryption translates data into another form, or code, so that only people with access to a secret key (formally called a decryption key) or password can read it. Encrypted data is commonly referred to as ciphertext, while unencrypted data is called plaintext. Currently, encryption is one of the most popular and effective data security methods used by organizations. Two main types of data encryption exist - asymmetric encryption, also known as public-key encryption, and symmetric encryption. The Primary Function of Data Encryption The purpose of data encryption is to protect digital data confidentiality as it is stored on computer systems and transmitted using the internet or other computer networks. The outdated data encryption standard (DES) has been replaced by modern encryption algorithms that play a critica...

Hello Friends .... Today we learn about the Morse Codes.... So let's Start..... Morse code is a method of sending text messages by keying in a series of electronic pulses, usually represented as a short pulse (called a "dot") and a long pulse (a "dash"). The code was devised by Samuel F. B. Morse in the 1840s to work with his invention of the telegraph, the first invention to effectively exploit electromagnetism for long-distance communication. The early telegrapher, often one who was at a railroad station interconnected with others along miles of telegraph pole lines, would tap a key up and down to send a succession of characters that the receiving telegrapher could read from tape (later operators learned to read the transmissions simply by listening). In the original version, the key down separated by a pause (key up) from the next letter was a dot (or, as it sounded to the telegrapher, a "dit") and the key down quickly twice in s...
Hello Friends .... Today we learn about the Video Games......... So let's Start..... Video games have been around since the early 1970s. The first commercial arcade video game, Computer Space by Nutting Associates , was introduced in 1971. In 1972, Atari introduced Pong to the arcades. An interesting item to note is that Atari was formed by Nolan Bushnell , the man who developed Computer Space. He left Nutting Associates to found Atari, which then produced Pong, the first truly successful commercial arcade video game. Pong was a great hit when it came out. Move your cursor to get the slides to bounce back the moving square -- it will speed up as you progress. That same year, Magnavox offered the first home video game system. Dubbed the Odyssey , it did not even have a microprocessor! The core of the system was a board with about four-dozen transistors and diodes. The Odyssey was very limited -- i...
