Virtual classes allow for multiple inheritance in object-oriented programming languages. The diamond problem arises when two parent classes have a common grandparent, causing ambiguity. C++ solves this by making the grandparent a virtual class. Proper class hierarchy structuring is important to avoid errors. A virtual class is a class that is allocated only once in […]
Virtual hosting allows a server to host multiple domains on the same machine, using one shared or multiple IP addresses. It is a cheaper alternative to dedicated and co-located servers, and often comes with bundled services. Virtual hosting accounts appear as your own server, making it ideal for small businesses and individuals. In a technical […]

A virtual address list is necessary for computers to locate and access virtual memory, and to manage memory partitions. It can also be used for virtual networks. The list registers the sources of virtual memory and details how memory is being used. A virtual address is similar to a home or work address, except that […]
Virtual memory is an area on a computer’s hard drive that allows programs to run without loading them into physical memory. When there isn’t enough RAM, the system uses virtual memory. It copies information from physical memory to the hard drive, freeing up space for new programs. Virtual memory is cheaper than buying additional RAM […]
Object-oriented programming has a pure virtual function that acts as a placeholder for other variables and can be changed on a per-user basis. A derived class is needed for it to work. Virtual functions have their own body, while pure virtual functions don’t. Pure virtual functions limit the amount of code the programmer has to […]
A PBX is a computerized device that connects businesses with the outside world, acting as a switchboard and offering features such as personalized greetings and conference calling. Virtual PBX is a third-party telephone hosting service that uses the internet as a switchboard, eliminating the need for physical equipment on the company’s premises. Computers can help […]
Virtual weight loss tools provide a visual representation of the user’s current and target weight, allowing them to track their progress and visualize changes. Users can customize their virtual model and some tools even allow them to upload photos for a more accurate result. These tools also provide nutritional information, diet tips, and exercise plans. […]
A virtual machine uses a host computer’s hardware to function and can connect to networks through the host’s network adapter. It can also connect to other virtual machines on the same host. Virtual machine networking is not portable but can be cost-effective. Software may be needed to create virtual networks. A virtual computer is one […]
A Virtual Tape Library (VTL) is a backup solution that combines tape backup emulation software with hard drive architecture for faster, more flexible, and cost-effective backup. It offers all the convenience of tape methodology with the speed and reliability of hard drives, and can store up to a terabyte of data or more. It can […]
A virtual ISP purchases internet services from a provider and resells them to customers. The provider offers reduced rates for a minimum amount of business, resulting in low overhead and more profit. However, there is a lack of control over service delivery, and marketing can be transparent or private labeled. A virtual Internet service provider, […]
A virtual machine monitor allows multiple virtual machines to run on one computer, using its resources non-transparently. It prevents crashes and boosts the performance of weaker computers, but relies on the health of the network and can lead to downtime if the network is unreliable. A virtual machine monitor is a program that monitors the […]
Virtual interior design is the use of online tools or software to digitally design interiors. Users can experiment with different designs and save their customizations. Some tools are sponsored by home supply companies and offer product recommendations. As the name suggests, virtual interior design is an activity that uses an online tool or software application […]
Virtual machines replicate physical machines and allow multiple systems to exist on one computer. Virtual migration simplifies OS upgrades, disaster recovery, and reduces operating costs. It also allows for testing and debugging of new systems, isolates crashes, and can be used for legacy software. Operational costs are reduced by hosting multiple applications on fewer servers. […]
Parallel virtual machine software allows multiple computers to connect and lend their processing power to solve complex problems. It was created in 1989 and has two parts: the application and the library of interface routines. It supports two models: functional and data parallels. C, C++, and Fortran are the programming languages used. The source code […]
