In computer science, an interpreter is a computer program that directly executes, i.e. performs, instructions written in a programming or scripting language, without previously compiling them into a machine language program. An interpreter generally uses one of the following strategies for program execution:
Early versions of Lisp programming language and Dartmouth BASIC would be examples of the first type. Perl, Python, MATLAB, and Ruby are examples of the second, while UCSD Pascal is an example of the third type. Source programs are compiled ahead of time and stored as machine independent code, which is then linked at run-time and executed by an interpreter and/or compiler (for JIT systems). Some systems, such as Smalltalk, contemporary versions of BASIC, Java and others may also combine two and three.
The General Certificate of Education Advanced Level (short form: GCE Advanced Level), or more commonly, the A Level, is a school leaving qualification offered by educational bodies in the United Kingdom and the British Crown dependencies to students completing secondary or pre-university education. A number of countries, including Singapore, Kenya, Mauritius and Zimbabwe have developed qualifications with the same name as and a similar format to the British A Levels. Obtaining A Level or equivalent qualifications is generally required for university entrance.
A Levels are generally worked towards over two years and split into two parts, with one part studied in each year. The first part is known as the Advanced Subsidiary Level, A1 Level or AS Level (the AS Level acronym was previously used for the separate Advanced Supplementary Level qualification). The second part is known as the A2 Level and is more in depth and academically rigorous than the A1 Level. The AS Level is a qualification in its own right, and the AS Level combined with the A2 Level forms the complete A Level qualification. Up to June 2009 a third Special / Advanced Extension Award level was available for the brightest candidates.
Computer science is the scientific and practical approach to computation and its applications. It is the systematic study of the feasibility, structure, expression, and mechanization of the methodical procedures (or algorithms) that underlie the acquisition, representation, processing, storage, communication of, and access to information. An alternate, more succinct definition of computer science is the study of automating algorithmic processes that scale. A computer scientist specializes in the theory of computation and the design of computational systems.
Its fields can be divided into a variety of theoretical and practical disciplines. Some fields, such as computational complexity theory (which explores the fundamental properties of computational and intractable problems), are highly abstract, while fields such as computer graphics emphasize real-world visual applications. Still other fields focus on challenges in implementing computation. For example, programming language theory considers various approaches to the description of computation, while the study of computer programming itself investigates various aspects of the use of programming language and complex systems. Human–computer interaction considers the challenges in making computers and computations useful, usable, and universally accessible to humans.
