An API is an “Application Programming Interface” through which programmers can integrate external applications and their data into their own programs. Unlike BaaS, use of the external application is not visible; it is only accessed within the internal flow of the program. Example: an interface to output definitions when terms are entered (a dictionary). See also: “Backend as a Service” (BaaS).

“App” (short for “application”) is a general term for all kinds of programs: on the Internet, in mobile systems or under the operating system. Examples: weather information; smart home controllers; office software.

“Augmented reality” (acronym: “AR”) refers to reality augmented with artificial elements. Example: displaying informational text at tourist sites. See also: “Mixed Reality” and “Virtual Reality.”


A “backend” comprises system-facing components (data processing, especially on servers), while a “frontend” is more user-facing (data input/output). See also: “Server.”

“Backend as a Service” (BaaS) refers to an interface that can be used to access a development environment within a browser. It makes it easier to create backend applications for apps and mobile websites in a browser with the help of abstract steps. Modules for integrating social media and data or for messaging are often provided. See also: “App,” “Backend” and “Cloud.”

“Big data” refers to very large data volumes from sources such as the Internet (especially social media), the financial industry or intelligent agents. The data is stored, processed and analyzed with special tools. Examples: tracking the spread of epidemics through announcements of illness on Twitter; identifying developing trends.

A program for displaying the multimedia, hypertextual content on the World Wide Web (webpages), which can also load complex apps (such as Office Web apps and online games). Examples: Mozilla Firefox, Google Chrome. See also: “World Wide Web.”


A cloud provides infrastructure, platforms and applications through the Internet, so you no longer need to have your own server for data storage/processing and application development. Example: Dropbox as a “network drive” on the Internet.

In its original form, a cookie is a text file on a computer. It is saved and/or accessed when you visit webpages and contains data such as your browsing history, preferences and access data. Cookies basically serve to store information associated with a website/domain locally on the computer for a specific amount of time and transmit it back to the server upon request. Examples: language settings, user authentication.


In a traditional network, a server runs multiple clients. In contrast, in a decentralized structure, the services, data and data traffic are distributed across many computers. This guarantees availability even if one subnet goes down, for example. Example: file-sharing networks. See also: “Server,” “Client.”

“Disruptive technology” refers to an innovation that may completely displace an existing technology (product or service) from the market. Examples: digital cameras (instead of analog cameras); smartphones (mobile phones).

The DNS (“Domain Name System”) is a globally distributed directory service that translates easy-to-remember domain names (such as mitegro.de) into the hard-to-remember binary IP addresses of the corresponding computers (and vice versa). Example: mitegro.de <>

A domain is a cohesive section of the Internet used for addressing computers. Domain names are structured hierarchically: They start with a top-level domain (e.g., “de” for the German namespace), then contain the domain name (e.g., “mitegro”) and can then be further specified through subdomains (e.g., “mail”). A domain name like “mail.mitegro.de” cannot be created at will; domain name registrars govern the assignment process.



A framework provides a simplifying structure for programming, which can be accessed within applications.

User-facing interface; see “Backend.”


GNU is a freely available operating system related to Unix; the core (kernel) relies on Linux, but it also provides numerous applications, libraries and extras for developers. GNU is an acronym for “GNU’s Not Unix,” where “GNU” represents the GNU project. See also: “Kernel.”



“Infrastructure as a Service” (Iaas) describes a flexible structure that replaces the classic setup, in which an organization operates its own server, with demand-oriented leasing of servers, storage etc. (a cloud solution). See also: “Cloud,” “On-Premises.”

The Internet of Things (IoT) should be understood not as a second, parallel internet, but rather as an extension of the established Internet, where not only computers, but any suitable objects are connected to the network so they can communicate with each other and perform various tasks for their owners. Example: reordering consumables (milk, toner) when they run out, including delivery tracking (printer message: “Ready to print again tomorrow as of 3 p.m.”).

IPv6 (“Internet Protocol Version 6”) is a standardized method for transferring data on networks, especially the Internet. Thanks to 128-bit addressing, it can connect significantly more computers to each other than the previous (32-bit) version IPv4, and it governs the procedure for forwarding data between subnets (routing). See also: “IP,” “Routing.”



The term “artificial intelligence” (AI) groups together methods (algorithms) to allow computers to carry out tasks that require intelligence when performed by humans. The goal is to automate intelligent behavior. Example: self-learning systems, digital assistants/agents. See also: “Algorithm.”



“Mixed reality” (MR) refers to reality augmented with artificial (computer-generated) perception. MR differs from “augmented reality” through the generation of virtual parts (a VR headset), and from “virtual reality” by being embedded in a “true” reality. See also: “Augmented Reality,” “Virtual Reality.”


NAS (“Network Attached Storage”) is an easy-to-manage server for storing files. NAS allows storage capacity to be provided on a computer network without much overhead (network drive).

NAT (“Network Address Translation”) is the general term in computer networks for processes that automatically replace address information in data packets with other information in order to link different networks. Network address translation is typically employed on routers, for example, to allow use of IP addresses to address computers that share a common public IP address. Example: server with public IP address that offers various services (email, Web). See also: “IP Address.”


Software whose source code is public, i.e., can be viewed, modified, used and shared by third parties, is called “open source.”


PHP (originally an acronym for “Personal Home Page Tools”) is a scripting language used mainly for creating dynamic websites or Web applications (with database access and function libraries). Its syntax is based on that of programming languages like Perl and C, one of the most widespread programming languages.

“Predictive Analytics” refers to analyzing current and historical data for prediction purposes. Example: recommending products on the basis of past purchases, or of products that other users also bought.




Cloud-based Software; see: “Software as a Service.”

In a Software as a Service (SaaS) model, software does not run locally; instead, it is used as a service provided by an external service provider (a cloud solution). See also: “Cloud,” “On-Premises.”

SQL (“Structured Query Language”) is a database language. It is used both to define data structures (data tables and relationships) and to process (insert, modify or delete) and retrieve SQL data/data records. Examples: output all customers who have already purchased smart home products; provide the content data to a specific webpage (URL). See also: “Predictive Analytics,” “PIM,” “PHP.”


TCP (“Transmission Control Protocol”) is a protocol that specifies how data is exchanged on a network. TCP is one of the central standards of the Internet alongside the “Internet Protocol” (IP). See also: “Internet,” “IP.”


A URL (“Uniform Resource Locator” – an Internet address or WWW address) is first and foremost the unique address of a specific webpage. It can also refer to directories of webpages, email addresses etc. Example: http://www.mitegro.de/home.html. See also: “World Wide Web,” “Hyperlink.”


“Virtual Reality” (VR) refers to a thoroughly artificial reality that is computer-generated and offers interactive immersion into this artificial environment through a VR headset. Example: a skiing experience from within your living room that feels real. See also: “Augmented Reality,” “Mixed Reality.”



“Everything as a Service” (Eaas or Xaas) relies exclusively on cloud solutions, meaning all services that can be implemented through the Infrastructure as a Service (IaaS – i.e., servers), Platform as a Service (PaaS – i.e., run-time environments) and Software as a Service (SaaS – i.e., apps) levels. See also: “Cloud,” “App.”
