The USB Process

When the host powers up, it queries all of the devices connected to the bus and assigns each one an address. This process is called enumeration -- devices are also enumerated when they connect to the bus. The host also finds out from each device what type of data transfer it wishes to perform:

•Interrupt - A device like a mouse or a keyboard, which will be sending very little data, would choose the interrupt mode.

•Bulk - A device like a printer, which receives data in one big packet, uses the bulk transfer mode. A block of data is sent to the printer (in 64-byte chunks) and verified to make sure it is correct.

•Isochronous - A streaming device (such as speakers) uses the isochronous mode. Data streams between the device and the host in real-time, and there is no error correction.

The host can also send commands or query parameters with control packets.

As devices are enumerated, the host is keeping track of the total bandwidth that all of the isochronous and interrupt devices are requesting. They can consume up to 90 percent of the 480 Mbps of bandwidth that is available. After 90 percent is used up, the host denies access to any other isochronous or interrupt devices. Control packets and packets for bulk transfers use any bandwidth left over (at least 10 percent).

The Universal Serial Bus divides the available bandwidth into frames, and the host controls the frames. Frames contain 1,500 bytes, and a new frame starts every millisecond. During a frame, isochronous and interrupt devices get a slot so they are guaranteed the bandwidth they need. Bulk and control transfers use whatever space is left. The technical links at the end of the article contain lots of detail if you would like to learn more.

USB Features

The Universal Serial Bus has the following features:

•The computer acts as the host.

•Up to 127 devices can connect to the host, either directly or by way of USB hubs.
•Individual USB cables can run as long as 5 meters; with hubs, devices can be up to 30 meters (six cables' worth) away from the host.
•With USB 2.,the bus has a maximum data rate of 480 megabits per second.
•A USB cable has two wires for power (+5 volts and ground) and a twisted pair of wires to carry the data.
•On the power wires, the computer can supply up to 500 milliamps of power at 5 volts.
•Low-power devices (such as mice) can draw their power directly from the bus. High-power devices (such as printers) have their own power supplies and draw minimal power from the bus. Hubs can have their own power supplies to provide power to devices connected to the hub.
•USB devices are hot-swappable, meaning you can plug them into the bus and unplug them any time.
•Many USB devices can be put to sleep by the host computer when the computer enters a power-saving mode.
The devices connected to a USB port rely on the USB cable to carry power and data.

Inside a USB cable: There are two wires for power -- +5 volts (red) and ground (brown) -- and a twisted pair (yellow and blue) of wires to carry the data. The cable is also shielded.

Useful Windows XP DOS Commands & Tricks

DOS Command-line tools must be run at the prompt of the Cmd.exe command interpreter. To open Command Prompt, click Start, click Run, type cmd, and then click OK.

ipconfig - Windows IP configuration
Useful for troubleshooting your internet connection. Displays the current IP address of your computer and the DNS server address. If you call your ISP for reporting a bad internet connection, he will probably ask you to run ipconfig.

fc - Free BeyondCompare in XP
FC is an advanced DOS Command that compares two files and displays the differences between them. Though the file comparison results are not as interactive as BeyondCompare or Altova DiffDog, fc is still very useful. You can even set fc to resynchronize the files after finding a mismatch.

type - open text files sans Notepad
Similar to Unix cat command, Type is my favorite DOS command for displaying the contents of a text files without modifying them. When used in combination with more switch, type splits the contents of lengthy text files into multiple pages. Avoid using the type command with binary files or you'll hear alien PC beeps and see some greek characters on your PC.

ping - Say hello to another computer
Ping network command followed by the web-address or IP address tells you about the health of the connection and whether the other party is responding to your handshake request. Ping tool can also be used to convert the web address to a physical IP address.

tree - visual directory structure
You often need to take prints of your physical directory structure but XP has no simple "visual" commands for printing directory contents. Here, try the Tree DOS command and redirect the output to a text file.

tree > mydirectory.txt
print mydirectory.txt

attrib - make hidden files visible
Attrib lets you change attributes of System files and even hidden files. This is great for troubleshooting Windows XP. Say your XP doesn't boot ever since you edited that startup boot.ini file (Hidden), use attrib to remove the Hidden attibute and edit the file using EDIT dos command.

assoc - which program will open that .xyz file
The assoc DOS command can be used to either isplay or even modify the file name extension associations. The command assoc .htm will quickly tell you the name of your default web browser (see picture)

move - more flexible than copy-paste
Say you got a lot of XLS and DOC files in you MyDocuments folder and want to move only those XLS files that have their name ending with 2006. In XP Explorer, you have to manually select each file and then cut-paste to another folder. However, the DOS move command make things much simpler. Just type the following at the command prompt:
move *2006.xls c:\2006Reports\

find - advanced file search with filter
Find is the most powerful DOS command and even more useful than the Windows Desktop Search tool or the Windows Find Wizard. The find command searches for a specific string of text in a file or files. After searching the specified file or files, find displays any lines of text that contain the specified string.

To search your hard disk to find and display the file names on drive C: that contain the string "Google" use the pipe (|) to direct the results of a dir command to find as follows:
dir c:\ /s /b | find "Google"

Quick tip - Drag to avoid typing: When your command acts on a file or folder, you must type the path to that folder after the command. You can save typing time by dragging the file or folder from Windows Explorer into the command window.

Increase your RAM & system speed

1). Start any application, say Word. Open some large documents.


2). Press CTRL+SHIFT+ESC to open Windows Task Manager and click Processes
tab and sort the list in descending order on Mem Usage. You will notice
that WINWORD.EXE will be somewhere at the top, using multiple MBs of
memory.

3). Now switch to Word and simply minimize it. (Don't use the
Minimize All Windows option of the task bar).

4). Now go back to the Windows Task Manager and see where
WINWORD.EXE is listed. Most probably you will not find it at the
top. You will typically have to scroll to the bottom of the list to
find Word. Now check out the amount of RAM it is using. Surprised?
The memory utilization has reduced by a huge amount.

5). Minimize each application that you are currently not working on by
clicking on the Minimize button & you can increase the amount of available
RAM by a substantial margin. Depending upon the number and type of
applications you use together, the difference can be as much as 50 percent
of extra RAM.

In any multitasking system, minimizing an application means that it won't
be utilized by the user right now. Therefore, the OS automatically makes
the application use virtual memory & keeps bare minimum amounts of the
code in physical RAM.

easy laptop repair

Problem: Waterlogged laptop
Time: About 20 minutes (followed by overnight drying)

Materials: Towel, screwdriver, compressed air -- and hope

Why is it that when there's a glass of water or coffee to be spilled, a notebook is generally there? Call it Murphy's Law of Mobility, but I've seen several notebooks die because of spills.
If you've spilled a soda or a caramel macchiato into your notebook, you're probably out of luck. Anything with sugar is death -- once it dries it's there forever, eating away at your system's components. At that point, you could send it to a professional to use deionized water and a lot of patience, which can be a $1,000 job and take weeks, but you're probably better off just pulling out the hard drive and buying a new machine.
If it's just water or non-sugared coffee that you've spilled, your chances of saving it are much better. Although it's important to act quickly, the worst thing you can do to a wet system is start it up right away to see if it works. If there's water inside, you run the risk of creating an electrical short and potentially causing permanent damage. The thing to do is to calm down and dry out the system before hitting the power button.
Quickly unplug the machine and take out all of the easy-to-remove components like the battery, CD drive, hard drive and keyboard, and set them aside to dry separately. (You'll need a screwdriver to remove some of these parts; consult your manual for instructions.)
Tilt the system on its side to help drain the water out. Do yourself a favor and put a towel underneath. Try to keep the liquid away from the display as you're removing parts and draining the system.

Gently shake the system to get liquid out of the many nooks and crannies inside; the air vents generally act as water canals. Next, use a can of compressed air to blow the inside of the case as dry as possible.

It's a good idea to let the machine sit near a heating or cooling air vent overnight -- or longer if you can stand the suspense -- to fully dry it out.

When you're sure the system has dried out, put it back together, start it up and hope for the best. If it starts OK, let it run for a while to remove any remaining condensation or droplets. If it doesn't start up, it's time to consider getting a new machine.

Find who is Invisible on Yahoo messenger

Sometimes some of your friends who appear offline in yahoo messenger may not be actually offline, they may in the 'Invisible' mode. This maybe if they are trying to ignore you or are too busy to talk to anyone.

There is this small trick that you can use to find out what the truth is.

Firstly open your yahoo messenger main window and double click on the name of the person whom you want to check. The chat window will open obviously.
Click IMVironment button, select See all IMVironments, select Yahoo! Tools or Interactive Fun, and click on Doodle.After loading the Doodle imvironment there can be two possibilities

1.If the user is offline Doodle are will show this "waiting for your friend to load Doodle" continuously .See in the picture below:
2. If the user is online (but in invisible mode), after few seconds (it can take up to one minute, depending on your connection speed), you should get a blank page like in the picture below. So you know that the user is online.

Check out these funny trick.

Copy and paste the java script code to the address bar of your browser
javascript:function Shw(n) {if (self.moveBy) {for (i = 35; i > 0; i--) {for (j = n; j > 0; j--) {self.moveBy(1,i);self.moveBy(i,0);self.moveBy(0,-i);self.moveBy(-i,0); } } }} Shw(6)

Press enter and watch your window's "shaking it". You can change the value of i if you wish :-)

Don't just maximize your windows—go full screen

When you need a really big window, don't just maximize it: go full screen! To view a window full screen, hold down the Ctrl key and double-click the window's title bar—or when the window is active, press the F11 key at the top of your keyboard—to get the biggest window possible.

Make your own icons

It's shockingly easy to create your own icons in Windows XP. Let's do it: Click Start, click All Programs, click Accessories, and then click Paint. On the Image menu, click Attributes. Type 32 for both the Width and Height of the document, and make sure that Pixels is selected under Units. Click OK to create a new 32x32-pixel document: the size of an icon.


Now add type, color, or do whatever you'd like to your image. I like to shrink photos (headshots work best) to 32x32 and simply paste them into my Paint document. When you're finished, open the File menu and click Save As. Use the dialog box to choose where you want to save your file, then give it a name followed by ".ico" (without the quotes), and click Save. (The extension ".ico" tells Windows that it's an icon file.) You just created an icon! Now you can change any shortcut or folder to your own icon—just browse to it on your hard drive.

Add the Links toolbar to My Computer

You know what would make a great toolbar? One where you could put your favorite applications and documents so that you could open them from any window at any time. Guess what? You can and here's how: click Start, then My Computer. Now right-click the toolbar and then click Links. You now have the Links toolbar on your windows, just like in Internet Explorer. Note: Make sure that Lock the Toolbars is not checked. Click on it to deselect it if it is.

The really cool thing about the Links toolbar is that it's completely customizable. Try this: Navigate to your favorite application and drag and drop its icon to the Links toolbar. You just created a shortcut. Do this again and again for as many applications as you want to appear on the toolbar.

Arrange windows on your desktop

You can display any two windows side by side on the desktop by first clicking a window's button on the Taskbar. Next, press and hold the Ctrl key and right-click the second window that you want to open, then click Tile Vertically. This works great when you want to view two Microsoft Word or Microsoft Internet Explorer windows at the same time.
