What is a quantum computer Quantum computer is a type of computer which uses quantum mechanics to perform computations. Classical computers process data in the form of 0 and 1. But in the case of quantum computers, the 0 and 1 form is extended. It can store and process data in qubits. Qubits can process data in 01 or 10 form i.e. it stores information in both true [...]
WWAN is also known as a wireless wide area network. In WWAN a wireless connection is made through WWAN device. It is most commonly used in cellular devices. You can use hotspot in mobile to share internet through WI-FI also. But mainly mobile data connectivity is used to get access to the internet. Wireless Wide Area Network (WWAN) In the local area network, you can get access to [...]
What is a freeware software Freeware software is a type of software that you can use free for a lifetime. Freeware vs free software: You cannot modify code in freeware software and also you cannot distribute software without author permission. While free software can provide you with source code that you can modify and also redistribute the software. Freeware vs shareware software: You can use freeware software for [...]
WMAN is a wireless metropolitan area network that can cover a whole city. It is larger than WLAN (wireless local area network) and smaller than WWAN (wireless wide area network). WMAN is managed by any private organization or government agencies. Wireless MAN is accessed by only authorized users. It can cover a distance of 30 miles. WMAN can establish a network between different buildings or university campuses within [...]
What is workstation A workstation computer is a special type of computer which has more processing power than a normal PC. You can do more work than a normal PC can do. Normal PC can do stuff like browsing the internet, word processing, listening to music etc. But a workstation can do video editing, playing high graphics games, 3D animation, and complex simulation. They have higher RAM and [...]
WPAN is also known as a wireless personal area network. WPAN is a type of wireless network connection between personal devices like tablets, smartphone, computer and PDA (Personal digital assistants). The network connection in WPAN is either made via Bluetooth or Wi-Fi. Bluetooth can connect devices in a range of 30 meters. In case of Wi-Fi, you can chat, share documents, calls with your home mates or friends. [...]
A multicore processor has multiple processing units (cores) on a single chip. Each core of the processor performs different tasks. For example, if you are using WhatsApp on the mobile then one core is handling WhatsApp and other core of processor may be used for downloading a document at the same time. Diagram of multi-core processor A multicore processor works like a human. Suppose one human has one [...]
A hybrid topology is a combination of two or more topologies. For example, if you combine Ring and star topology to make bigger network then it will be called hybrid network or hybrid topology. Different topologies are combined via the hubs and switches. Diagram of hybrid topology Most common hybrid topologies include star-bus and star-ring network. Features of hybrid topology: 1) Flexible in size: New topologies and nodes [...]
Laser stands for light amplification stimulated emission of radiation. Definition of a laser printer: A laser printer is a type of photocopier machine that uses laser light and toner to print a document. A laser printer uses a selenium coated drum which uses electrical charges for printing purpose. The laser light makes print by mixing electrical charges and toner. After printing is complete the electrical charges and extra [...]
For building smaller software, developers usually don’t follow any rules and just start coding with little planning. But for building commercial high-end software companies follow rules and regulations. In software engineering, we use software development life cycle (SDLC) to develop complex software. It is an international method for software development. So let me first define what SDLC is. Phases of SDLC Definition of SDLC SDLC or software development [...]
