I’ve always been fascinated by the way in which different computing concepts get converted into common knowledge and how, depending on who’s speaking about a certain concept, that person will tend to assimilate it according to their own field of knowledge and action. This article is the result of a conversation I had with a colleague who interpreted DevOps as related to operational efficiency and facilitating business objectives – which is a perfectly accurate view when looked at from their perspective.
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 board) construction characteristics, such as trace impedances, their length, number of loads and their distribution, etc.
Now that the second decade of the 21st century is about to end, sustainability and digitalization have become challenges all city areas must face. With this in mind, the 40th FITUR edition, which just took place in Madrid, has greatly focused on the need to incorporate new technologies to tourist destinations and turn them into “Smart Destinations”.
A fundamental feature of wireless (duplex) bidirectional communication systems is the way to separate the transmitted and received signals. We almost always find that the standard either establishes alternating them in time intervals, with the device quickly switching between transmission and reception, or transmitting them in different frequency bands and separating them by means of radiofrequency filters.
The acronym CAD comes from the English expression Computer Aided Design. It involves the use of computer technology to aid in the design of a product. In the case that concerns us now, it would involve designing housings for communications devices. In short, CAD is the drawing or graphical tool that replaces the traditional drawing board in drafting the design object.
