In the field of telecommunications, the backbone is a central node in the network that usually consists of high-performance network components and is used to interconnect or link local or regional networks. The backbone often forms the top level in the hierarchical structure of the network. external-link

Backend Integration

The term backend (also called back end) refers to the area of information technology that deals with the processing and storage of data in the background of software, apps, websites, and other applications. It is the counterpart to the front end, which describes the visible user interface of applications. external-link


The connection between a subordinate network node and a central network node is called a port. external-link


Bandwidth refers to the frequency range in which electrical signals are transmitted. A larger bandwidth enables a greater amount of information to be transmitted per unit of time. Therefore, the bandwidth has a direct influence on the download speed and the speed at which web pages are built. The term bandwidth is often used in connection with the transmission of digital signals, although the transmission rate or data rate is usually meant. Nevertheless, there is a connection between the bandwidth and the transmission rate, since the achievable transmission speed depends on the bandwidth and the coding. external-link

Base Station Subsystem

In the GSM network, the base station subsystem (BSS) ensures the connection between the mobile devices and the switching subsystem. external-link

Baseboard Management Controller 

The baseboard management controller (BMC) is a dedicated service processor that oversees the physical condition of a computer, network server, or other hardware device. It utilizes sensors and communicates with the system administrator through a separate connection, allowing for independent monitoring and management. external-link

Basic Service Set

With a WLAN according to IEEE 802.11, which is referred to as a Basic Service Set (BSS), two stations can communicate directly with each other wirelessly without the need for additional active components such as Wireless Access Points (WAP). Instead, communication is handled via the WLAN adapters or Wireless Network Interface Controllers (WNIC). external-link

Batch function

The batch function generates the data for the batch view by utilizing the MapReduce technique on the original dataset, especially for large datasets. external-link

Big Data

Big data refers to the vast amount of data, including both structured and unstructured data, that businesses receive regularly. The quantity of data, however, is not the crucial factor. What really counts is how organizations make use of this data. By analyzing big data, businesses can gain valuable insights that can inform better decision-making and strategic planning. external-link

Big Data Analytics

The process of analyzing big data to reveal valuable insights, such as concealed patterns, correlations, market trends, and customer preferences, is known as big data analytics. These insights can be used by organizations to make informed decisions that can positively impact their business operations. external-link

Big Data as a Service

Big data as a service refers to the provision of data platforms and tools by a cloud provider. Its purpose is to assist organizations in processing, managing, and analyzing vast amounts of data. This enables them to derive valuable insights, enhance business operations, and attain a competitive edge. external-link

Big Data in Core Telco

Big Data in Core Telco refers to the vast and diverse data generated within telecommunications networks. It includes structured and unstructured data from network devices, call records, customer interactions, and more. This data is collected, stored, and analyzed to optimize network operations, improve customer experience, and make data-driven decisions. The three Vs of Big Data (volume, velocity, variety) characterize the data. Technologies like distributed computing and real-time analytics are used to process this data, uncover patterns, and predict network failures. Insights gained from Big Data analysis enhance network efficiency, reliability, personalized services, and drive innovation in telecommunications. external-link

Big Data Infrastructure

Examples of IT infrastructure, such as Hadoop-based systems and SAP HANA, have the capability to store unstructured data and perform processing and analysis on them.

Bill of Materials

The BOM, or bill of materials, is an essential list of all the necessary parts and materials required to produce a product. Without it, manufacturing the product would be impossible. However, while the BOM specifies what needs to be made, it does not provide instructions on how to actually manufacture the product, which is where the BOP, or bill of process, comes into play. external-link

Bill of Process

The Bill of Process (BOP) is comprised of a set of productive operations which together lead to the  production of the complete product. The BOP may be accompanied by constraints regarding the possible orderings of the production operations, which however generally do not fix the sequence completely. This allows a "flexible production". See also eBOP. external-link


The process of invoicing/billing encompasses the entire workflow from capturing usage data to generating the invoice. external-link

Binding Corporate Rules Privacy

The corporate-level data protection policy is referred to as Binding Corporate Rules Privacy (BCRP) and ensures a consistently high level of data protection within the Telekom Group.,group%20of%20undertakings%20or%20enterprises. external-link

Bit stream access

Digital data access as opposed to physical access. external-link

Blind Source Separation

The objective of blind source separation (BSS) is to separate the unknown source signals from their mixtures, and in some cases, to estimate the unknown mixing channels. BSS achieves this by using only the information available within the mixtures observed at the output of each channel, with little or no knowledge about the source signals and mixing channel. BSS has numerous potential applications in areas such as audio, speech, music, image, video, biomedical, and communication signal processing, including enhancement and recognition. external-link

Block (asset)

Essential components or units that can be integrated and utilized with other building blocks to realize the functionality of a data space. external-link

Block Heat Power Station

CHP (Combined Heat and Power) plants, also known as BHKW (Block Heat Power Station), are facilities used for generating heat and electricity. They operate based on the principle of combined heat and power generation. CHP plants contribute to climate protection by reducing emissions. external-link

Blue Screen of Death

A blue screen is a common term used to describe the display of a blue-lit screen with text that appears on Windows operating systems when a serious error occurs. This error may be triggered by various causes, such as program errors, faulty drivers, or defective hardware. external-link


An English word for "Blaupause" is "blueprint." It refers to a concept that is based on previous experiences and disseminates knowledge about technologies and processes for implementing specific use cases. external-link

Branch (Git HUB)

A software repository may contain numerous software versions, which can include a beta version for experimental purposes and a stable version for production. These versions are typically organized into branches within the repository. external-link


The term "broadband" is not internationally defined consistently. However, the broadband strategy of the German government aims for nationwide basic coverage with minimum speeds of 1 Mbit/s. By 2018, speeds of at least 50 Mbit/s should be available across the country. At the EU level, the Digital Agenda for Europe sets the goal of achieving widespread coverage of at least 30 Mbit/s and providing speeds of 100 Mbit/s to at least 50% of European households by 2020. external-link
