SLA IT Training - How to Convert a Basic Disk to a Dynamic Disk?

All disks are basic disks by default. When you need to take advantage of the functionality that dynamic disks provide, you must convert the basic disks to dynamic disks. You can convert a basic disk to a dynamic disk without losing existing data.

For the conversion to be successful there must be atleast 1 MB of free unpartitioned space available on the basic disk. This 1 MB is necessary to store the dynamic disk database, which tracks the configuration of all dynamic disks in the computer. If Windows XP professional created the existing partitions, it will have automatically reserved the 1 MB of space required for conversion. If another operating system or a third-party utility program created the partitions prior to upgrading, there is a chance that no free space is available. In that case, you will likely have to repartition the drive so that 1 MB of space is reserved as blank space.

During the conversion, all primary and extended partitions become simple dynamic volumes, and the disk will join the local disk group and receive a copy of the dynamic database.

SLA PC Hardware Training Chennai - Faqs: Why do we need Virtual Memory?

People wonder about this all the time : “My computer has two gigs of RAM. Why would I need more?”

Like many other things in the computer industry, virtual memory was born out of necessity. Fairly early on in personal computer evolution, it was decided that a computer would never need more than 640 KB ( yes, kilobytes) of memory. Oops. For DOS it was fine, mostly, but once graphical operating systems came into the world, the number of resources needed jumped significantly.

Flash back to the late 1980s/early 1990s – if you had 4MB of RAM in your system, you were doing well. Very well, in fact, because RAM cost over $100 per megabyte. If you wanted more memory for windows to use, then you had two choices – one was to mortgage your property, and the other was to use another source: virtual memory.

Hard disk space was and probably always cheaper per megabyte than RAM, simply because of the technology involved. So, while hard disks might be slower than RAM, they are bigger and cheaper. Using space on them for virtual memory made a ton of economic sense then and still does today.
