A language translator is a system software that converts programs written in a high-level language or assembly language into machine language (binary code) that the computer CPU can understand.

Since computers can only understand machine language (binary code), programs written in high-level or assembly languages need to be translated into machine code before execution. This translation enables the computer to perform the instructions specified by the programmer.

• Computers only understand machine language, so programs written in human-friendly languages need converting.
• They help detect and report errors in the code.
• They optimize programs for faster and more efficient execution.
• Different types of translators serve different purposes based on language types and usage scenarios.

Modern e-book readers such as Amazon Kindle or Kobo have become popular due to their lightweight design, portability, and eye-friendly screens.
Unlike traditional screens that emit light, these devices use a special display technology called E-Ink (Electronic Ink).

• E-Ink is a special type of ink used in e-book readers, mimicking the appearance of ink on paper.
• It is light, power-efficient, and comfortable for reading for long periods without eye strain.
• E-Ink technology uses tiny microcapsules with charged particles that move to create text and images.

Animation formats are special file types or containers made to store moving images or animated sequences. FLI and FLC are examples of animation file formats created by Autodesk for frame-based animations. MPEG (Moving Picture Experts Group) (MPEG files usually have extensions like .mpg, .mpeg, .mp4) is a widely used video format that supports motion content, while QuickTime (QT/Moov), developed by Apple, works as a multimedia container for both animations and videos.

On the other hand, SGI (Silicon Graphics Image) is not an animation format. It is an image file format designed for Silicon Graphics workstations and is mainly used for storing static raster images. Since it does not support animated or moving content, it cannot be considered an animation format like the others.

An Expert System is a type of Artificial Intelligence (AI) program designed to mimic human expert reasoning in a specific domain. It uses a knowledge base (containing expert facts and rules) and an inference engine (which applies logic to that knowledge) to solve complex problems that normally require human expertise.
Expert systems are most useful in areas that involve logical reasoning, pattern recognition, and decision-making based on well-defined rules.

However, Decoupling is not a problem area where expert systems provide assistance. Decoupling refers to separating interconnected components or systems to reduce dependency, commonly used in engineering, programming, or system design, not in reasoning-based problem solving.
