Change the size of virtual memory

     If you receive warnings that your virtual memory is low, you'll need to increase the minimum size of your paging file. Windowssets the initial minimum size of the paging file at the amount of random access memory (RAM) installed on your computer plus 300 megabytes (MB), and the maximum size at 3 times the amount of RAM installed on your computer. If you see warnings at these recommended levels, then increase the minimum and maximum sizes.

- Open System by clicking the Start button , clicking Control Panel, clicking System and Maintenance, and then clickingSystem.

- In the left pane, click Advanced system settings. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

- On the Advanced tab, under Performance, click Settings.

- Click the Advanced tab, and then, under Virtual memory, click Change.

- Clear the Automatically manage paging file size for all drives check box.

- Under Drive [Volume Label], click the drive that contains the paging file you want to change.

- Click Custom size, type a new size in megabytes in the Initial size (MB) or Maximum size (MB) box, click Set, and then click OK.

     Increases in size usually don't require a restart, but if you decrease the size, you'll need to restart your computer for the changes to take effect. We recommend that you don't disable or delete the paging file.

Librarian Makes Windows’ Libraries Much Easier to Manage

     Windows: Libraries are a great feature of Windows 7 and up that allow you to pool several folders in one place. Librarian improves on the concept by allowing you to manage those collections more easily.

Librarian allows you to add or remove folders, change default save location, and select the type of collection all in one place. It doesn't do much that you can't do from elsewhere, but many of these options are scattered throughout the OS. This app consolidates all of those options in one, simple window.

AHCI vs IDE

AHCI and IDE are two modes in which a hard drive communicates with the rest of the computer system using a SATA storage controller. SATA hard drives can operate in a backward-compatible PATA/IDE mode, a standard AHCI mode or vendor-specific RAID. AHCI stands for Advanced Host Controller Interface and is a faster mode of operation compared to IDE. RAID mode also enables and makes use of AHCI.

AHCI gives software developers and hardware designers a standard method for detecting, configuring, and programming SATA/AHCI adapters. AHCI is separate from the SATA 3 Gbit/s standard, although it exposes SATA's advanced capabilities (such as hot swapping and native command queuing) such that host systems can utilize them.

	AHCI	IDE

What Is 'Telnet'? What Does Telnet Do?

     Telnet is an old computer protocol (set of programmatic rules). Telnet is famous for being the original Internet when the Net first launched in 1969. Telnet stands for 'telecommunications network', and was built to be form of remote control to manage mainframe computers from distant terminals. In those original days of large mainframe computers, telnet enabled research students and professors to 'log in' to the university mainframe from any terminal in the building. This remote login saved researchers hours of walking each semester. While telnet pales in comparison to modern networking technology, it was revolutionary in 1969, and telnet helped pave the way for the eventual World Wide Web in 1989. While telnet technology is very old, it is still in some use today by purists. Telnet has evolved into a new modern version of remote control called 'SSH', something that many modern network administrators use today to manage linux and unix computers from a distance.

     Telnet is a text-based computer protocol. Unlike Firefox or Google Chrome screens, telnet screens are very dull to look at. Very different from Web pages that sport fancy images, animation, and hyperlinks, telnet is about typing on a keyboard. Telnet commands can be rather cryptic commands, with example commands being 'z' and 'prompt% fg'. Most modern users would find telnet screens to be very archaic and slow.
