Apple’s M1-based MacBook Air, MacBook Pro, and Mac Mini have been the focus of computer news for the last half-year because of their surprisingly high-performance.
The history of computing has been dominated by the von Neumann computer architecture, also known as the Princeton architecture, after the university of that name, in which one common memory stores the operating system, user programs and variables the programs operate on.
There are many different requirements and expectations in the field of computer security and it may be as well to set out what some of them are. Computation is everywhere, from the ubiquitous iPhone to the military computer in an underground installation, and it is unrealistic to think that one…
Computer security is always a hot topic, but what do we mean by security and why do systems seem to be ever vulnerable. Comparing hardware to software helps understand vulnerabilities in software security.
As in all systems where there are opposed ideologies, there is a kind of cold war in which advances on one side need to be balanced by advances on the other. In encryption, the availability of increased computing power at low cost made it easier to break codes, but it…
Once upon a time, the cause of data corruption would be accidental. A dropout on a tape or interference picked up on a cable would damage a few bits. Error correction was designed to deal with that.
The arrival of 5G brings both opportunities and challenges to communications, media and entertainment companies, as well as the original equipment manufacturers (OEMs) working to support them.
The requirements for data transmission have changed out of all recognition since the early days of computing where the goal was simply to make something that worked. Today that’s the easy part.
Many people and cultures celebrate special New Year dates. Organizations designate fiscal years. Broadcasters traditionally mark their new technology year mid-April, at annual NAB Shows. Old habits die hard.
There are many types of codecs, all used for specific purposes to reduce file sizes and make them easier to distribute down a limited bandwidth pipe. Lossy compression and Lossless compression are the two most common categories of data compression used to reduce the size of data without significant loss…
The subjects of timing, synchronizing and broadcasting are inseparable and in this new series John Watkinson will look at the fundamentals of timing, areas in which fundamental progress was made, how we got where we are and where we might be going.
PTP - as a precise network timing technology has been available for nearly two decades. It is already widely used in Telecommunication networks, Finance and Trading platforms, substation automation networks and many more industries. Every industry has its own demands such as target accuracy on the end nodes, or whether…
