kódoláson

Kódolás, also known as encoding, is the process of converting data into a specific format or code, making it suitable for transmission, storage, or processing. This process is fundamental in various fields, including computer science, telecommunications, and data security. Encoding can be applied to different types of data, such as text, images, audio, and video.

In text encoding, characters are represented by specific codes. One of the most common text encoding standards is ASCII (American Standard Code for Information Interchange), which uses 7 or 8 bits to represent 128 or 256 characters, respectively. However, ASCII is limited to representing only English letters, numbers, and punctuation marks. To support a wider range of characters, including those from different languages and special symbols, more advanced encoding standards have been developed, such as Unicode and UTF-8.

Image encoding involves compressing and converting image data into a specific format, such as JPEG, PNG, or GIF. These formats use different algorithms to reduce the size of the image file while maintaining acceptable quality. Audio and video encoding follow similar principles, using techniques like MP3 for audio and H.264 for video to compress and convert these types of data into efficient formats suitable for storage and transmission.

Kódolás plays a crucial role in ensuring data integrity, security, and compatibility across different systems and platforms. By converting data into a standardized format, encoding enables efficient data transmission, storage, and processing, facilitating the seamless exchange of information in the digital age.
