AP Computer Science Principles Qs & As 2023/2024 Heuristic - ans-a technique designed for solving a problem more quickly when classic methods are too slow, or for finding an approximate solution when classic methods fail to find any exact solution High-Level Programming Language - ans-A high-level language (HLL) is a programming language such as C, FORTRAN, or Pascal that enables a programmer to write programs that are more independent of a type of computer. Languages are considered high-level since they are closer to human languages and further from machine languages. Low level programming language - ans-Low-level languages those languages which are extremely close to machine language. aka Assembly languages. The closest languages after Assembly to Machine language are C and C++. Machine code is known as low level because unlike high level programming languages it doesn't need anything else like compilers or something. It runs directly on the processor and they are extremely architecture specific.(not like english) natural language - ans-Natural-language processing (NLP) is an area of computer science and artificial intelligence concerned with the interactions between computers and human (natural) languages, in particular how to program computers to fruitfully process large amounts of natural language data. machine code - ans-the elemental language of computers. It is read by the computer's central processing unit (CPU), is composed of digital binary numbers and looks like a very long sequence of zeros and ones. Ultimately, the source code of every human-readable programming language must be translated to machine language by a compiler or an interpreter, because binary code is the only language that computer hardware can understand. machine learning - ans-Machine learning is a field of computer science that uses statistical techniques to give computer systems the ability to "learn" (e.g., progressively improve performance on a specific task) with data, without being explicitly programmed. lossy - ans-permanently eliminating certain information, especially redundant information. When the file is uncompressed, only a part of the original information is still there lossless - ans- Continues...
