A hybrid topology is a computer network layout type that uses multiple topologies such as a bus-star combination. The hybrid is sometimes also known as tree topology where the linear bus topology is used as the trunk of the tree and the star topology becomes the tree branches. The hybrid combines the advantages of the…
Optical character recognition also known as text recognition is a technology that is used to convert images and other scanned documents into computer-editable text. The OCR technology uses software and an optical character reader to convert images, handwritten and scanned documents into machine text readable documents. An optical character reader is categorized as an input…
A star network topology is a type of network layout where all the devices are connected to a central point. The central device can be a network switch or a hub. The layout of the network has the hub or switch at the center of the network and then all other network components are connected…
Magnetic Ink Character Recognition (MICR) is a technology that is used to read characters printed using special magnetic material. They are categorized under input computer devices. MICR is used mostly in banks to verify the authenticity of bank cheques and other financial documents. The characters on these documents are printed using special ink that contains…
CD, DVD, and Blu-ray are types of optical discs that are used for the permanent storage of data. They are used to store music, video, images, and other variety of data. The main difference between the 3 types of optical discs is the storage capacity and the types of data that each disc can store. Again…
A mesh network topology is a network layout where each device is connected. The connection can be wired or wireless. Each node on the network is capable of communicating with the other and they also act as a relay to pass messages to their destination. The most practical and common type of mesh is wireless…
A Read Only Memory (ROM) is a type of computer memory that is non-volatile. As the name suggests data is written once and read many times on these memories. It is classified as computer primary memory alongside RAM. They are used to store firmware software for devices such as computers, routers, and gaming devices, among…
A router is a networking components device used to connect two networks that use different protocols. It is mainly used as a gateway to connect the LAN and WAN or internet networks. They are used to direct traffic from source to destination by choosing the best path for the message. Network routers can be wired,…
A bus or linear bus topology is a type of computer network layout where all devices are connected to a single cable called the linear bus. The cable is also called a backbone or trunk. Bus cable is shared by the devices and allows data to flow in both directions. All devices have an equal…
The CPU registers are high-speed access storage areas that are within the processor. They are also known as computer registers. Registers are inbuilt within the processor to increase the speed of access. They are faster than cache and main memory. They are used to temporarily store data that is currently being executed on the CPU….
