What is mesh topology “A type of network topology in which every node or device is connected to every other node or device in the network” Every node transfers its data but also receives data from other connected nodes. This type of topology is used in a wireless network and wide area network. All the nodes are directly connected i.e. point-to-point connection is made between every two nodes. [...]
Definition of hybrid topology “A type of topology which is built by connecting two or more different topologies.” For example, the arrangement of computers in an office makes ring topology. And in another office computers are attached in the form of star topology. So if you connect these two offices i.e. combining ring and star topology will make a hybrid topology. Diagram of Hybrid Topology You can combine [...]
In a remote procedure call, the client request some processing to the server computer. The server computer is placed in a remote location. The client sends parameters with the request it sends to the server. The parameters are passed either by value, by reference, or linked in the cloud location.

For example, chrome browser, audio player, MS word program runs at the same time. The running of multiple programs/tasks at the same time is handled by the operating system. If you have a single CPU (central processing unit) or single processor then the operating system gives a small [...]
We often store our data on the hard drive of our PC, laptop or workstation. The data we store on a personal computer can be hacked, stolen or attacked by a virus. Maybe our hard drive fails to function so there is a chance of data loss. Similarly, big companies have to store their data and there is a need for data security and data retrieval for the [...]
What is passive optical local area network (POL) Passive optical LAN uses fiber optics to make a network. In POL the speed of data transfer is high. You can easily video conference, audio share and browse the internet fast. There are 3 main components of POL i.e. Optical Line Terminal (OLT), Optical Splitter, Optical Network Unit (ONU) or Optical Network Terminal (ONT). POLAN Data travel from OLT to [...]
POL or passive optical local area network is an inexpensive solution to connect different devices to the internet. POL was first time introduced in 1987 by British Telecommunications. There are 3 major components of POL that are:- Optical Line Terminal (OLT)Optical SplitterOptical Network Terminal (ONT) POLAN OLT or optical line terminal is placed in main exchange i.e. at ISP office. OLT is connected to the optical splitter through [...]
