CAT, namely computer-aided translation, refers to the technology of using computer technology to assist human beings in translation. The development of computer-aided translation technology has greatly improved the efficiency and quality of translation and has become one of the indispensable tools in modern translation industry.

The main feature of CAT technology is that the translated content is segmented into clauses and word segmentation, and the translation process is decomposed into several small tasks, which are completed with the help of computer software. CAT software can help translators realize many functions such as terminology management, translation memory, machine translation, terminology database and so on, which greatly improves the efficiency and quality of translation.

CAT technology is widely used in translation industry. In the fields of international trade, science and technology, law and medicine, there is a great demand for translation, and the requirements for translation quality are also very high. Using CAT technology can greatly improve the efficiency and accuracy of translation, reduce the cost and improve the competitiveness of translation.

However, CAT technology is not perfect. Due to the complexity and fuzziness of language, CAT technology may lead to incorrect or inaccurate translation in some cases. In addition, CAT technology can not completely replace human translation, because human translation also needs to consider the cultural background of the language, language habits and other factors.

Generally speaking, CAT technology is a very useful computer-aided translation technology, which can greatly improve the efficiency and quality of translation and reduce the cost. With the continuous development of computer technology, it is believed that CAT technology will be continuously improved and perfected, which will bring more convenience and development to the translation industry.
