Diagram Of Extended Star Topology Extended Star Topology is a type of network topology in which multiple star topology networks are connected through central switch/hub. Each connected star topology is connected through sub-hub switch to main central switch/hub as shown in the diagram. This topology is a type of tree star topology. If any network terminal (PC Or Mobile Device) becomes faulty, then other computers or devices will [...]
Windows Phone's first version, named Windows Phone 7, was released in October 2010. Then in 2012, Windows Phone 8 was released. Windows Phone 7 uses a Windows CE-based kernel.

Most of the apps of Windows [...]
Centralised data processing is computer processing that takes place in a single server or CPU. A mainframe computer or a single high-performance machine handles data management, data storage, and computation. Different types of clients are connected to a single central server. The clients which are connected to the centralised server are smartphones, laptops, tablets or desktop computers. The processing speed in centralised data processing depends upon the processor [...]

A data warehouse is a repository or data store in which data is stored, queried, and analyzed. The data comes from different sources like marketing research data, educational data, political data, scientific data, company data etc. A data warehouse is just like a store in which you store unused items like an electric generator or extra things. But in the case of a data warehouse, you store structural [...]
What is computer network A computer network is a type of connection between two or more computers. After networking computers, they share resources, data and internet connections with each other. A computer network is either a local area network (LAN) or a wide area network (WAN). A local area network is made within a building meaning computers within one building are connected to each other. In a wide [...]
What is centralized data processing Centralized data processing is a type of processing which is done on a single server/system. All the nodes/computers are connected to a single system. The system resides in a single location and nodes from other locations are connected to that system. The system which is centralized has a lot of processing power. All the data resides in the same system or server. There [...]
Definition of Broadcast Network: A type of network in which audio and video content is transferred from a single source to multiple devices. Broadcast network is also found in bus and star topology. In bus topology, one node transfers data to all the nodes and the target node gets the data. Similarly, a central router sends data to all the attached nodes in a star topology. Radio and [...]
What is data warehouse A data warehouse is a space where structured data is stored, analysed and fetched. The data can be historical data or new data. Small and medium-sized businesses don’t use data warehouses but use cloud-based services for storing data. Big organizations and multinational companies use data warehouses for storing their large data. Suppose a large company uses a data warehouse to store employee's data. If [...]
