Word of the Day

Today’s WhatIs.com Word of the Day is carbon nanotube  (CNT),  a hollow, cylindrical carbon structure with hexagonal graphite molecules attached at the edges. Nanotubes, which are grown in a laboratory, are strong and exhibit many thermal and electrical properties that are desirable to chip makers. Carbon nanotubes have the potential to be used as semiconductors, for example, potentially replacing silicon in a wide variety of computing devices.

Word of the Day: colocation

Margaret Rouse Margaret Rouse Profile: Margaret Rouse

Word of the Day

Today’s WhatIs.com Word of the Day is colocation, a data center facility in which a business can rent space for servers and other computing hardware.  There are several reasons a business might choose a colo over building its own data center, but one of the main drivers is the capital expenditures (CAPEX) associated with building, maintaining and updating a large computing facility. In the past, colos were often used by private enterprises for disaster recovery and redundancy. Today, colos are especially popular with cloud service providers. Continued…

Margaret Rouse Margaret Rouse Profile: Margaret Rouse

Word of the Day

Today’s WhatIs.com Word of the Day is hardware emulation, the use of one hardware device to mimic the function of another hardware device. An administrator must use hardware emulation if he needs to run an unsupported operating system (OS) within a virtual machine (VM). In such a scenario, the virtual machine does not have direct access to server hardware. Instead, an emulation layer directs traffic between physical and virtual hardware. Continued…

Word of the Day – application virtualization

Margaret Rouse Margaret Rouse Profile: Margaret Rouse

“Unfortunately, some apps can’t or shouldn’t be virtualized. For instance, kernel-based device drivers won’t work with any of the application virtualization products on the market today. Adobe Acrobat, for example, which has a printer driver, can’t be virtualized. “Bridget Botelho

Today’s WhatIs.com Word of the Day is application virtualization, which separates the installation of an application from the client computer that is accessing it. There are two types of application virtualization: remote and streaming. Remote applications run on a server and end user devices view and interact with applications over a network by using a remote display protocol. With streaming applications, the virtualized application is actually executed on the end user’s computing device. When an application is requested, the required components are downloaded to the local computer on demand.
