■ Power off the virtual machine.
■ Verify that the virtual disk is not mapped or mounted. You cannot expand a virtual disk while it is mapped or mounted.
■ Verify that the virtual machine has no snapshots.
■ Verify that the virtual machine is not a linked clone or the parent of a linked clone.

What does the x stand for in AGP 8x?
What does the x stand for in AGP 8x?
- Times Graphic Speed
- Times FSB Speed
- Times CPU Speed
- Times original AGP Speed [Times the bus speed ]
EXPLANATION
AGP (Accelerated Graphics Port) is a high-speed 32-bit port from Intel for attaching a display adapter to a PC. It provides a direct connection between the card and memory, and only one AGP slot is on the motherboard.AGP was introduced as a higher-speed alternative to PCI display adapters, and it freed a PCI slot for another peripheral device. The brown AGP slot is slightly shorter than the white PCI slot and is located about an inch farther back. AGP is superseded by PCI Express.

Macro, Micro, Pico, Femto and Umbrella are all types of what?
Macro, Micro, Pico, Femto and Umbrella are all types of what?
- Cell sizes in a GSM network
- GSM filters
- GSM interfaces
- Uplink and downlink channels
EXPLANATION
GSM mobile phone networks are "cellular," which means that mobile phones connect to it by nearest cell.MACRO cells can be regarded as cells where the base station antenna is installed on a mast or larger building structures that are taller than an average roof-top level. Cell radius is typically from 1 up to 35 km.
MICRO cells are cells whose antenna height below average rooftop level and are typically used in urban areas. Size is from 400 m to 2 km.
PICO cells are small cells whose diameter is only few dozen meters; they are used mainly in indoor applications.
UMBRELLA cells: A layer with micro cells is covered by at least one macro cell, and a micro cell can in turn cover several pico cells. A covering cell is called an umbrella cell.
