Syllabus

WEEK 1
Introducción a Networking
¡Bienvenido al curso de los bits y bytes de las redes informáticas! En la primera semana de este curso, cubriremos los conceptos básicos de las redes informáticas. Aprenderemos sobre los modelos de red TCP / IP y OSI, y cómo las capas de red trabajan juntas. También cubriremos los conceptos básicos de dispositivos de red como cables, hubs y switches, enrutadores, servidores y clientes. También exploraremos la capa física y la capa de enlace de datos de nuestro modelo de red con más detalle. Al final de este módulo, sabrás cómo todas las diferentes capas del modelo de red se unen para crear una red.

WEEK 2
La Capa De Red
En la segunda semana de este curso, exploraremos la capa de red con mayor profundidad. Aprenderemos sobre el esquema de direccionamiento IP y cómo funciona la división en subredes. Exploraremos cómo funciona la encapsulación y cómo los protocolos como ARP permiten que se comuniquen diferentes capas de la red. También cubriremos los conceptos básicos de enrutamiento, protocolos de enrutamiento y cómo funciona Internet. Al final de este módulo, podrás describir el esquema de direccionamiento IP, entender cómo funciona la división en subredes, realizar operaciones matemáticas binarias para describir subredes y comprender cómo funciona Internet.

WEEK 3
Las capas de transporte y aplicación
En la tercera semana de este curso, exploraremos las capas de transporte y aplicación. Al final de este módulo, podrás describir los puertos y sockets TCP; identificar los diferentes componentes de un encabezado TCP; mostrar la diferencia entre los protocolos orientados a la conexión y los protocolos sin conexión, y explicar cómo se utiliza el TCP para garantizar la integridad de los datos.

WEEK 4
Servicios de red
En la cuarta semana de este curso, vamos a explorar los servicios de redes. Aprenderemos sobre por qué necesitamos DNS y cómo funciona. También te mostraremos por qué DHCP hace que la administración de la red sea una tarea más simple. Al final de este módulo, podrás describir cómo funcionan los DNS y DHCP; cómo las tecnologías NAT ayudan a mantener las redes seguras, y cómo las VPN y los proxies ayudan a los usuarios a conectarse y mantenerse seguros.

WEEK 5
Conectarse a Internet
En la quinta semana de este curso, exploraremos la historia de Internet, cómo evolucionó y cómo funciona en la actualidad. Entenderemos las diferentes formas de conectarse a Internet a través de cables, conexiones inalámbricas y de bodega, e incluso conexiones de fibra. Al final de este módulo, podrás definir los componentes de las WAN, y describir los conceptos básicos de las redes inalámbricas y celulares.

WEEK 6
Solución de problemas y el futuro de las redes
¡Felicidades, has llegado a la última semana del curso! En la última semana de este curso, exploraremos el futuro de las redes de computadoras. También cubriremos los aspectos prácticos de la solución de problemas de una red utilizando sistemas operativos populares. Al final de este módulo, podrás detectar y solucionar una gran cantidad de problemas comunes de conectividad de red utilizando las herramientas disponibles en los sistemas operativos Microsoft Windows, MacOS y Linux.
