  Polynomials   Algebraic expressions that contain monomials are considered polynomials. The study of these expressions is directly related to arithmetic operations.  Polynomials are algebraic expressions that have monomials formed by a coefficient and a literal part. Polynomials are algebraic expressions that have monomials formed by a coefficient and a literal part. A polynomial is an algebraic expression formed by monomials and arithmetic operators.  The monomial is structured by numbers (coefficients) and variables (literal part) in a product, and the arithmetic operators are: addition, subtraction, division, multiplication and power. To better understand what a polynomial is, see some examples: 5 Coefficient:  5 Literal part: Any variable raised to zero, ie x⁰ = 1 → 5 . x⁰ Arithmetic Operators: Multiplication. Two . x. and Coefficient: 2 Literal part: a. and Arithmetic Operators: Multiplication. 3 . x. y + (4 .x : 2 .x)  Coefficient: 3, 4 and 2 Literal...

  Operating Systems   The operating system is a set of programs that control the operation of a computer, that is, a sequence of instructions written to be interpreted by a computer. Its function is to manage system resources (define which program receives processor attention, manage memory, create a file system in others. Operating system allows a person to access and control parts of the computer without having specific technical knowledge, making the computer accessible.  Evolutions of Operating System Components   Now as the operating systems emerged and developed until reaching the versions we know today, we can present their evolution during the past times until the current version.  First generation   The first electronic computers were introduced during the 1940's and 50's. At that time, all programming was done in machine language, usually by connecting wires to breadboards to control basic functions as complex operating systems did not exist. In t...
