3. SERVERS

   • Client
     • Client-server denotes a relationship between cooperating programs in an application, composed of clients initiating requests for services and servers providing that function or service.
   • P2P
     • In a P2P network, no single provider is responsible for being the server. Each computer stores files and acts as a server. Each computer has equal responsibility for providing data. In the client-server model, many users trying to access a large file, such as a film, would put strain on one server.

4. CODING

   • ERRORS
     • SYNTAX
       • A syntax error is an error in the source code of a program. Since computer programs must follow strict syntax to compile correctly, any aspects of the code that do not conform to the syntax of the programming language will produce a syntax error.
     • LOGIC
       • In computer programming, a logic error is a bug in a program that causes it to operate incorrectly, but not to terminate abnormally (or crash). ... Unlike a program with a syntax error, a program with a logic error is a valid program in the language, though it does not behave as intended.
