It's a myth to say that Ubuntu (or any Linux) needs a swap partition. This is certainly the preferred way of working, and is most efficient, but Linux can also use a single swap file located in the root partition, just like Windows or Mac OS X.
A volume must have at least 15 percent free space before Disk Defragmenter can completely defragment the volume. If you have less free space available, the operation will run, but only partial defragmentation will result.
The System applet provides access to general system properties. You also can open the System
applet by right-clicking Computer and choosing Properties. The first page of the System property applet provides basic information about your system, including OS version, installed memory, CPU type, and registration information.
Some Control Panel applets control fairly simple sets of options, while others are relatively complex. As in other Windows platforms, the Windows Server 2008 Control Panel serves as a control center for configuring hardware and operating system settings.
One of the things we spend most of our time doing at a PC is waiting for applications to start. Larger applications, particularly, can take what seems like an eternity - OK, 10 to 15 seconds on a fast PC - before they're ready to use. And small programs, even though they load quickly, don't always "pop" on screen as quickly as one would like.
Bad memory can manifest itself in anything from frequent error messages and crashes to your system simply not starting. Errors in your computers memory (RAM) aren't always consistent, either; they can be intermittent and can get worse over time.
You can optimize Vista all you want, possibly shaving 15 or 20 seconds off your boot time, or you can approach the problem from a different angle.

Windows Vista animates almost every visual component that makes up its sparkling new interface. While these affectations may be cute, they create two performance problems. For one, they slow down the motion, causing windows, menus, and listboxes to take longer to open and close, all of which makes your PC feel sluggish. Second, they consume CPU cycles that would otherwise be used to handle processor-intensive tasks like virtual memory and gameplay.
When you select Tools > Folder Option in an Explorer window. The View tab contains settings that affect how much information Explorer shows you, arranged in alphabetical order.
To avoid some of the drawbacks of Vista's Sleep power-saving mode, you can hibernate your PC. hiberfil.sys saves a copy of everything in your PC's memory (RAM) onto your hard disk before it shuts down.
More bits gets you access to more memory. The processor inside your PC communicates with your system memory (RAM) with numeric addressing. Thus the maximum amount of memory a 32-bit processor can address is 232 bytes, or 4 gigabytes.
