La informática es la ciencia que permite el tratamiento automático de la información mediante computadoras. Un computador es una máquina electrónica que procesa y almacena información para transformarla en información útil, y está compuesto de hardware físico y software intangible. La CPU es la unidad central de procesamiento que realiza operaciones y controla la memoria principal y auxiliar, donde se almacenan los datos y programas.
Un sistema informático es un sistema que permite almacenar y procesar información; como todo sistema, es el conjunto de partes intencionadas: en este caso, hardware, software y personal informático.
Antibacterial Activity of Stem Bark Extracts of Oroxylum indicum an Endangere...IOSR Journals
The present work has been under taken to study the antibacterial activity of stem bark extracts of O.
indicum against disease causing gram negative and gram positive bacteria. Antimicrobial activity of solvent
extracts of stem bark of Oroxylum indicum has been studied to find out its activity against four important
bacterial strains Bacillus subtilis, B. cereus, Staphylococcus albus and S. aureus . The antimicrobial activity of
the stem bark extracts was done through well diffusion method and by measuring the inhibition zone around the
disc. The results revealed that the aqueous extracts of O. indicum exhibited antimicrobial activity against all the
microbes under study. The results provided evidence that the species O. indicum can be used as a potential
source of antimicrobial agent.

The efficacy of Andrographis paniculata (AP) extract was studied on atrazine induced hepatic damage in rats. Ethanolic extract of AP (150mg/kg body weight) was found to protect the male wistar rats from hepato toxic action of atrazine as evidence by significant reduction in the level of lipid peroxidation and increased the antioxidant defense system activity in the atrazine intoxicated rats. However, AP treatment ameliorated the effects of atrazine suggesting it as potential antioxidant against atrazine induced oxidative stress.

Normal şekilde, sınıfı kullanan kişi, o sınıftan bir örnek oluşturabilme iznini public(herkese açık) yapılandırıcı sayesinde elde eder. Her programcının bilmesi gereken başka bir teknik daha vardır. Bir sınıf, kendi örneğini döndüren statik fabrika metodu ile de örneğini oluşturabilir. Boolean(basit boolean tipinin kutulanmış sınıf hali) sınıfından basit bir örnek.
Esta es la presentación sobre Economía, Objeto y Método para cumplir con la evaluacion del tema 1 en la asignatura Introducción a la Economía del pensum de Comunicacion Social. UFT.
Esta presentación es una puerta a la informática. Aquí encontrarás las definciónes y los usos de componentes de la computadora y la informática. También encontraras un juego, suerte.
2. Informática: Es una ciencia que permite
realizar el tratamiento de la
información de manera automática.
Computador: Máquina electrónica que
procesa y almacena información para
transformarla en información útil.
Hardware: Es la parte tangible es decir
son los componentes físicos ej. El teclado,
el CPU etc.
Software: Es la parte intangible es decir
son los programas ej. Paint, Microsoft
Word etc.
3. Memoria RAM: Memoria de acceso
aleatorio.
Memoria ROM: Memoria sólo de lectura.
Bit: Unidad mínima de un PC.
Byte: Unión de 8 Bit
5. El CPU está compuesto por las siguientes
partes:
► Unidad aritmética lógica que es donde se
realiza las operaciones ( + - * / = # < > )
► Unidad de control se encarga de
controlar y coordinar.
► Memoria principal que es el área de
datos (Números y Letras) y el área de
programas (Sistema operativo).
► Memoria auxiliar (CD, Flash, Disco duro,
6. SISTEMAS NUMÉRICOS
Tenemos los diferentes tipos de sistemas:
▬ Sistema binario= 0,1(2)
▬ Sistema decimal = 0,1,2,3,4,5,6,7,8,9,10
▬ Sistema octal= 0,1,2,3,4,5,6,7(8)
▬ Sistema Hexadecimal = 0,1, 2,3,4,5,6,7,8,9 a
partir del número 10 tova el valor de una
letra 10= A 11= B 12=C 13= D 14=E 15=F etc.
