There are a variety of mechanisms that help to achieve the objective – some new, others...
Parallel computing via multicore computers allow high processing capacity
Parallel computing is a form of computation in which two or more processors are used to solve a problem or task. The technique is based on the principle that some tasks can be split into smaller parts and solved simultaneously. Parallel computing has become the dominant paradigm when it comes to manufacturing processors, thus making it essential to know not only the...
Interpreting manufacturers’ datasheets
We’ve all heard the phrase that timing is everything. Nowadays, the buses that connect, for example, processors to main memory require very precise timing, in the order of tenths of nanoseconds. Manufacturers provide all this information in their datasheets, but it needs to be combined with the appropriate Input/output Buffer Information Specification (IBIS) models and PCB (printed circuit...
CSMA and media access control
Si dividimos un sistema de comunicación genérico en sus partes más “simples” podemos distinguir cuatro elementos: Un emisor, un receptor, un mensaje y un medio o canal para comunicarlo. Uno de los problemas que surgen desde que se establece la comunicación es el acceso al medio. Cuando tenemos un canal de comunicación compartido entre varios usuarios o estaciones es necesario contar con un...

High-speed Internet from space: The Starlink network
Accessing the Internet from space is not new, with many companies (OneWeb, Space Norway, Telesat, etc.) now offering it. More recently, however, a new participant has emerged on the scene promising something different – Starlink. SpaceX’s plan is to create a network of 12,000 satellites that fly from 350 to 1160 km above our heads and provide fast Internet access using lasers. Each satellite...
