Study Notes

Tendencias tecnológicas actuales: inteligencia artificial, IoT, 5G, realidad virtual/aumentada, blockchain, computación en la nube, RPA, edge computing, seguridad cibernética, automatización de pruebas, realidad mixta. Redes LAN: red de computadoras dentro de un área geográfica limitada, pueden ser cableadas o inalámbricas, comunes en entornos empresariales y hogares. Redes MAN: redes de computadoras que se extienden sobre un área geográfica relativamente grande, utilizadas para proporcionar conectividad de alta velocidad y ancho de banda, comúnmente utilizadas en entornos empresariales, gubernamentales y educativos. Redes WAN: redes de computadoras que se extienden sobre una gran área geográfica, utilizadas para conectar diferentes ubicaciones geográficas, se utilizan tecnologías de red de larga distancia, pueden ser propiedad privada o proporcionadas por proveedores de servicios de comunicaciones. Redes de Internet: conjunto de redes interconectadas que utilizan el protocolo de Internet (IP) para comunicarse entre sí, basada en una arquitectura de red en capas, utilizada para la comunicación, el intercambio de información y el acceso a los recursos en línea, los ISP son los encargados de proporcionar el acceso a Internet a los usuarios.

A hub and a switch are devices used in computer networks to connect multiple devices and allow communication between them.
A hub is a simple device that works as a signal repeater, transmitting signals to all connected devices.
A switch is a more sophisticated device that learns MAC addresses of connected devices and sends data only to the correct destination device.
Broadcast networks send data from one device to all others in the network, which can be inefficient and cause congestion.
Point-to-point networks connect devices directly, without intermediate devices like routers or switches.
Client-server networks divide devices into clients and servers, with servers providing services or resources to clients.
Gateways connect different computer networks and allow communication between them.
Routers direct network traffic between different networks and find the best route for data packets.
Routers can also provide security and advanced network management functions.
These network devices have different capabilities and are used in different situations depending on network needs.

Ports are unique identification numbers used to identify processes and services on network devices
Each service or process uses a specific port to communicate with other devices on the network
Ports are numbered from 0 to 65535, with well-known ports from 0 to 1023
The technology used to transmit data can significantly affect a network's speed, security, and capacity
Common network classifications based on transmission technology include structured cabling, wireless, satellite, fiber optic, and power line networks
Structured cabling networks use copper or fiber optic cables to transmit data
Wireless networks use radio or infrared waves to transmit data without physical cables
Satellite networks use communication satellites to transmit data between devices
Fiber optic networks use fiber optic cables to transmit data using light
Power line networks use existing electrical lines to transmit data and are often used in rural or remote areas for internet access.
