An algorithm describes a process that ends with a solution to a problem.

An algorithm solves a general class of problems.

Each individual instruction in an algorithm is well defined.

In the 1930s, the mathematician Blaise Pascal explored the theoretical foundations and limits of algorithms and computation.

Computer science focuses on a broad set of interrelated ideas.

The first electronic digital computers, sometimes called mainframe computers, consisted of vacuum tubes, wires, and plugs, and filled entire rooms.

An algorithm describes a process that may or may not halt after arriving at a solution to a problem.

By the mid 1980s, the ARPANET had grown into what we now call the Internet, connecting computers owned by large institutions, small organizations, and individuals all over the world.

In the early 1940s, computer scientists realized that a symbolic notation could be used instead of machine code, and the first assembly languages appeared.

A program stored in computer memory must be represented in binary digits, which is also known as ASCII code.
