Cryptocurrency: It’s a word that anyone who spends any time online is sure to have heard of by now. Decentralized digital cash like Bitcoin has made cryptocurrency, and by extension the blockchain, a hot topic for discussion, and the cryptocurrency known as Ethereum is one of the hottest.

But Ethereum isn’t technically just another cryptocurrency—it’s a whole decentralized computer network powered by a cryptocurrency called Ether. Instead of just being an alternative to the dollar, euro or pound, Ether has a specific application.

Ether can be traded for its cash value, and it is one of the most highly valued cryptocurrencies. But to simply call it a cash alternative misses out on a lot of what it’s actually for.

Placing a device’s OS in a locked-down secure state can limit access to applications while still taking advantage of the computational power of the cloud and the potential of employee interaction and collaboration--this is the working principle behind Microsoft Windows 10 in S mode (formerly known as Windows 10 S). As a modified version of Windows 10 Pro, the streamlined Windows 10 in S mode can still achieve computational performance and communication but with limits that deliver additional security in an enterprise or an academic environment.

Basically, Microsoft Windows 10 in S mode is a pre-configured version of Windows 10 Pro designed to be more secure but with the same level of performance. The most obvious limitation, however, is that while in S mode, Windows 10 can only download, install, and use applications that are verified and available from the Microsoft Store.
