What is a zettabyte?

Zettabyte – the storage capacity unit explained

Most of us are already well-acquainted with storage units such as megabytes, gigabytes, and terabytes. But a much larger unit needed to measure the data capacity in use worldwide. The zettabyte has been mapping global data traffic since 2012. But how much data is in a zettabyte? We explain the relationship to better-known units and how their conversion works.

Esc key

The Esc key and its most important functions

The Esc key at the top left of a PC keyboard is basically a relic from the days of command line-based operating systems such as DOS and UNIX. But even today, the Escape key proves extremely handy for many situations. It terminates processes in Windows, shuts down windows and menus, and, in combination with other keys, can launch Windows system functions.

Android emulator

Free Android emulators: 3 programs compared

Android emulators are used to add smartphone and tablet applications to desktop PCs. Installing them is quick and operating them is not particularly complicated. Even games and apps from Google's Play Store can be used. We compare three Android emulators for Windows 10 that are freely available and discuss their security risks.

What is metadata?

What is metadata?

Metadata is generated by many applications in the digital world. If this data is collected and analyzed en masse, it poses a serious risk to privacy. But metadata doesn’t have to be dangerous. The term is broad and encompasses a lot of useful techniques. In this article we’ll explore the meaning of metadata with some examples.

What is a yottabyte?

What is a yottabyte?

We tend to work with megabytes and gigabytes on a daily basis. The yottabyte, however – while the largest unit for data volumes – is less well-known. But this unit of information gives an exciting insight into how much data is in circulation worldwide. We’ll explain the size of a yottabyte and how it is converted into other units for storage capacity.

What is a terabyte?

What is a terabyte?

When you purchase a hard drive, you’ll likely come across the term terabyte which refers to the data quantity common storage media can back up. But the designation raises the question of “how large is a terabyte anyway”? Find out more about this unit of information, about the difference between terabytes and terabits, and how it can be converted into other units.

What is a petabyte?

Petabyte – what is it?

The byte is a unit of information that makes it easy to specify the storage capacity of data carriers. Large units such as petabytes are now commonly used to express growing data volumes globally in simple figures. But what is their capacity? We compare petabytes with known quantities such as megabytes or gigabytes and explain how their conversion works.

What is a nibble?

Nibble meaning – what is it?

While the term “nibble” is still largely unknown, units of information such as gigabyte and megabyte are used frequently. But what amount of data do these terms actually describe? To answer this question, we must understand the meaning of smaller units such as bits, bytes, and the nibble. Find out more about these units of information and how their conversion works.

What is a megabyte?

Megabyte – an explanation of the unit of digital information

What’s larger – a MB or a KB? And what is 1 GB in MB? You may have asked yourself these questions before. MB is the abbreviation for megabyte, a common IT storage unit. It tells you the size of a file or how much space it takes up on a data carrier. But what makes up a megabyte and how does it relate to other units of measurement?

What is a kilobyte?

Kilobyte – the unit of information explained

What is bigger: a KB or a MB? And how large is a kilobyte really? That’s a question most digital media users will have asked at some point. Sending files as email attachments, for example, requires an understanding of the kilobyte. But how is this information unit structured and how do you convert it to other units?
