Mobile Tips and Tricks

Mind Your Mobile Manners   

The mobiles industry wants as many people as possible to enjoy the benefits of mobile telecommunications and encourages individuals to use their mobile phones in a responsible manner and to be considerate and aware of situations where using their mobile phone might annoy others.

 1. When in doubt, always go out

When possible go outside or to another room to make your call if your call might disturb others. Also, features such as text messaging answering services, call diversion and vibration alert can be used to receive important calls without disturbing others.

 2. If you can't turn it off, use silent mode

If you need to keep your phone on for important calls, then turn it to silent or vibrate mode. It�s the ring of a mobile phone in inappropriate places and times such as at the tennis or in restaurants which annoys people the most.

3. When required turn your phone off and check its off

There are some places where people should never talk on a mobile phone or send text messages and where the ringing of a mobile phone or message alert is considered highly unacceptable, such as: movies, stage shows, weddings, funerals, concerts, speeches, classrooms and lectures. In these cases, turn your phone off and remember to check its off before you enter the venue. You can always check your voicemail, text messages or your answering service afterwards.

4. Keep your conversations private

People's sense of personal space varies in each situation. Making a call in a busy pub may be okay, but talking loudly in a confined space like a lift or on a train tends to infringe on others personal space. Be aware of where you are and who you are with and what others are doing before deciding to make or accept a call. In some situations it might be better to send a text message.

5. Speak softly

Mobile phones have very sensitive microphones that can pick even the softest voice, so there is no need to shout. If you are having trouble hearing the other caller, check that you have the volume on your phone set high enough.

6. You don't always have to answer- use your messaging service

It's a natural reflex to answer your phone if it rings, however, if you forget to put your phone on silent or vibrate mode and it rings at an inappropriate moment, send the call to voice mail or your answering service (usually by pressing the hang-up key).

7. Talk to the one you're with

If you receive a call during a conversation, send the call to your voicemail or answering service. Your first priority should be to the person you are with. However, if you are expecting an important call let the person you're with know before the call arrives and excuse yourself before accepting the call.

8. Don't send inappropriate messages

Messaging is a great way to communicate, but don't send offensive or threatening text, voice, picture or any other sort of message, because it is a criminal offence to use a mobile phone to menace or harass someone. Also receivers can save messages and easily identify you as the sender.

9. Respect others' privacy when using in-phone cameras

In-phone cameras shouldn't be used anywhere a normal camera would be considered inappropriate, such as in change rooms or toilets. You should ask for permission before you take someone�s picture. Also bear in mind that some venues do not allow the use of cameras and may refuse entry to anyone with one.

10. Ban the ring: not the phone

Wherever conversations are normally acceptable, venues can help by asking people to turn their phones to silent or vibrate mode rather than turning it off. This approach will help with compliance, especially for people who need their phone for important calls. Venues can also assist by reminding people to set their phones to silent mode, before they enter

USB 2.0 - Hi-Speed USB - FAQ

As an aside, USB mice and keyboards need only 1.5Mbits/s to function. That performance level is also named 'USB' by the USB Promoter Group.

To sum it up, USB 2.0 specification incorporates three speeds: Hi-Speed, Full-Speed and Low-Speed. You as a consumer don't need to figure out all the jargons. Just keep in mind that only 'Hi-Speed USB' and 'USB' host and devices exist.

How do I know if my PC has USB 2.0?
You can identify whether your PC has Hi-Speed or not relatively easy. Open Device Manager and expand the Universal Serial Bus section. There should be an "Enhanced" USB host controller present.

Windows 98 systems may use a different name, because Hi-Speed USB drivers in these operating systems are not provided directly from Microsoft (Windows ME, 2000 and XP get their drivers through Windows Update).

These drivers are provided by the manufacturer, and may carry the maker's name (i.e. ADS, Belkin, IOGear, Siig, etc.). There should also be two standard version USB host controllers present as well. They are embedded in the USB chip which routes the differing USB speeds accordingly without user intervention.

There are currently 6 manufacturers of the Hi-Speed USB host silicon themselves:

• ALi (Acer Labs)
• Intel
• NEC
• SiS
• VIA
• nVidia (shows as "Standard" controller

Any other brand name that appears in Device Manager would likely be an add-in Hi-Speed USB PCI card. The makers above do not make add-in cards, but they do make the chips that are used in them.

How do troubleshoot "unknown device" error listed in Device Manager?

• The USB device or the USB adapter requires its own power source. If your USB device or adapter came with an AC power "brick", try connecting it.
• Here's a likely one - the front USB ports on your PC case may be misconnected. I've seen them that way from the factory. It's a good idea to check the connections against specifications. The standard order of connection is Red, White, Green, and Black. No more than 4 wires per USB bank are needed.
• Defective device. Do not assume that all PC components work correctly out of the box. I've seen many new USB devices that do not work. If you can, try the device on another PC.
• All drivers are not installed. Some devices will require installing the driver package before plugging in the device. Some devices will also require basic USB files from the Windows CD before the unit will function. The general rule is to always follow installation directions precisely and to have the Windows CD ready.

How fast is USB 2.0?
USB 2.0 has a raw data rate at 480Mbps, and it is rated 40 times faster than its predecessor interface, USB 1.1, which tops at 12Mbps. Originally, USB 2.0 was intended to go only as fast as 240Mbps.

How will consumers benefit from USB 2.0?
With speed 40 times more than that of USB 1.1, USB 2.0 broaden the range of external peripherals that can be used on a computer. Even with multiple high-speed peripherals connected to a USB 2.0 bus, the system will less likely to hit the bandwidth bottleneck. The new specification also inherits the current USB's Plug and Play and hot-swapping capability as well as providing backward compatibility for USB 1.1 hardware, allowing existing user base to upgrade seamlessly.

Do USB 2.0 & USB 1.1 hardware work interchangeably?
You may have heard that USB 2.0 is "backward-compatible" with USB 1.0/1.1 (Full-Speed USB). While that's true, USB 1.1 is also forward-compatible with USB 2.0. Whenever a system has USB 2.0 ports, you'll find the "Enhanced" USB controller in Device Manager, but you will also find two other USB controllers. These two to maintain backward compatibility to USB 1.1 devices. Each USB 2.0 host actually has 3 chips onboard. The USB controller routes signals to the correct controller chip depending on how a device is recognized. Where a device is physically plugged in has no bearing on how it is routed. All ports on a USB 2.0 motherboard can host any USB devices at all as long as the system and devices are healthy.

The vast majority of USB 2.0 devices will work on older PCs and Macs. None should flat-out fail unless there are other issues with the system. Hi-Speed USB devices will revert to Full-Speed operation when connected this way. Understand that Hi-Speed is at least ten times faster than Full-Speed in actual operation, so the speed difference is quite noticeable - unless you have never experienced Hi-Speed, of course.

When it comes to USB hub compatibility between USB 2.0 and USB 1.1, here some facts:

• A powered hub is always preferable to unpowered.
• USB hub ports are not as capable or flexible as real PC ports so it's best not to expect the world of them.
• USB 1.1 (obsolete) hubs will work fine on USB 2.0 ports, but they cannot utilize USB 2.0 capabilities. They will default to slower speeds.
• Hi-Speed and Full/Low-Speed USB devices can coexist nicely on USB 2.0 hubs. Connecting such a hub to a USB 2.0 port is recommended.
• USB 2.0 hubs can be used on older USB 1.1 computers.
• Although it is said that you can "cascade" up to 4 hubs, problems may start to arise after two hubs, it's best to minimize hub usage if possible.
• Many USB devices don't work well on hubs. Cameras, scanners and especially USB drives are known to have problems with hub connectivity.
• Remember that "active USB extensions" are really just one-port hubs.

Will USB 2.0 replace USB 1.1?
Not entirely, because many products such as generic keyboards, mice, joysticks and audio speakers do not require the faster speed of the new USB 2.0 technologies. Only bandwidth-hungry devices, such as web cams and high-capacity storage systems, will need all the speed. However, next-generation systems will come with USB 2 ports rather than USB 1.1.

How do I distinguish between a USB 2.0 and a USB 1.1 devices? New logos designed by the USB Promoter Group allow consumers to easily identify the new USB 2.0 products. The new colorful logo for USB 2.0 is labeled USB Hi-Speed, and the new logo for USB 1.1 is labeled with USB Basic Speed. However, most people won't miss it as manufacturers often label USB 2.0 READY Or 40 times faster than USB 1.1, on the boxes.

Will USB 1.1 devices run any faster on a USB 2.0 bus?
No. However, the new USB 2.0 archiclecture allows more high-speed USB 1.1 devices, such as web cams, audio devices, to share the bandwidth. Developers need to follow USB 2.0 spec in order to design higher speed peripherals that can take advantage of the extra bandwidth. USB 1.1 devices still operate at 12Mbps at full-speed and 1.5Mbps at low-speed on a USB 2.0 bus. Even though USB 1.1 devices won't run any faster, they can work alongside of USB 2.0 devices on the same bus.

What are USB Hi-Speed and USB Basic Speed logos?
These logos are part of USB Promoter Group's branding program that ensures the quality of USB products. The USB 2.0 certified products would display a blue, white and red logo, bearing the words Certified and Hi-Speed. The classic USB 1.1 certified products would display a black and white logo with the words USB and Certified.

Under a license from USB-IF, products must pass the compliance tests before manufacturers can use one of the two trademarked logos. The Promoter Group will take legal actions on manufacturers that label either logo on their products, which have not passed the tests.

What happen if a USB 2.0 devices are plugged into a USB 1.1 systems?
The entire bus under the USB 1.1 root hub will slow to 12Mbps. The operating system will probably notify the user about the sub-optimal configuration and recommend for a better course of action.

If several USB 1.1 hubs are connected to a USB 2.0 bus, then each of the USB 1.1 hubs will get a full 12Mbps bandwidth.

What is the max? Length of a USB 2.0 cable?
5m. however, if you cascade 5 hubs with 5m USB cables, this will allow you to connect a device 30m away.

What do I need to use a USB 2.0 device?
The requirement is similar to that of USB 1.1, but all components will have to be USB 2.0 compliant. A successful USB 2.0 connection requires a USB 2.0 host controller card, a USB 2.0 driver and a USB 2.0 peripheral.

How much will it cost to upgrade to USB 2.0?
Around $80 to $150. Currently, Orange Micro., Adaptec and IO Gear are shipping USB 2.0 PCI cards, some of which even have FireWire ports. Interestingly, almost all USB 2.0 PCI cards include an internal port, which is probably for connecting internal USB 2.0 IDE enclosure or USB 2.0 front panel.

Will USB 2.0 arrive on mobile computers?
Yes, but not in integrated solution on laptops. You will need a USB 2.0 Card Bus card. Orange Micro. is shipping USB 2.0 compliant 4-port Card Bus card. Eventually, notebook vendors will adapt to USB 2.0 technology, and we will see USB 2.0 ports on laptops. This transition won't happen until 2002 at the earliest.

Which operating systems support USB 2.0?
Microsoft has released the official USB 2.0 driver for Windows XP and Windows 2000. The version is 5.1.2600. The software is available on-line at Windows Update website. (If you don't have a USB 2.0 card installed in your system, Windows Update won't list the USB 2.0 driver as an update.)

The software company is still considering USB 2.0 support for Windows ME, but it already has decided not to bring USB 2.0 to Windows 98 and Windows 98 SE. If you have Windows 98, you will have to rely on 3rd party USB 2.0 support from USB card manufacturer.

Do USB 1.1 cables work with USB 2.0 devices?
Ideally, yes. USB 2.0 architecture uses the same cables and connectors as USB 1.1 compliant products. Unfortunately, only 3 out of 11 cables on the market are certified as USB 1.1 compliant. You may run into the cables that cause problems connecting high-speed peripherals. To avoid negative user experience, most vendors include USB 2.0 compliant cables with their USB 2 PCI cards and peripherals.

How To Make That Your Home Page Nevr Being Changed?

Some websites illegally modify your registry editor and set their website as default home page, for stop this,

1. Right-click on the Internet Explorer icon on your desktop and select “Properties”.

2. In the “Target” box you will see “C:\Program Files\Internet

Explorer\IEXPLORE.EXE”.

3. Now by adding the URL of the site to the end of this it overrides any
Homepage setting in internet options:

Change the name of Multiple Files in WinXp

rename files in bulk by simply selecting multiple files nd pressing the F2 key. When you use this feature, the OS applies the name you enter to the first file and applies the same name with a number in parentheses to the other files you selected (the file extensions remain unchanged).

For Example if You Select the following files

* Winxp.doc
* Win98.xls
* Win95.jpg
* Win2000.gif

and rename the first file (Winxp.doc) to English.doc, XP renames the remaining files as follows:
* English (1).xls
* English (2).jpg
* Einglish (3).gif

What Is Lan , Man and Wan

LAN =A local area network (LAN) is a computer network covering a small physical area, like a home, office, or small groups of buildings, such as a school, or an airport. The defining characteristics of LANs, in contrast to wide area networks (WANs), include their usually higher data-transfer rates, smaller geographic area, and lack of a need for leased telecommunication lines.

WAN = A wide area network (WAN) is a computer network that covers a broad area (i.e., any network whose communications links cross metropolitan, regional, or national boundaries [1]). This is in contrast with personal area networks (PANs), local area networks (LANs), campus area networks (CANs), or metropolitan area networks (MANs) which are usually limited to a room, building, campus or specific metropolitan area (e.g., a city) respectively

MAN = A metropolitan area network (MAN) is a large computer network that usually spans a city or a large campus. A MAN usually interconnects a number of local area networks (LANs) using a high-capacity backbone technology, such as fiber-optical links, and provides up-link services to wide area networks and the Internet.

What are Viruses and bacteria? How They affect the Computer?

Virus: A Computer virus is a programme that can infect other programmes by modifying them. A Copy Of virus can deamge a number of programmes. A Virus is like Other programmes. The Only Difference is that it attaches itself to anothor programme and executes secretly every time the host programme is executed. Avisrus has many stages of activity like a dormant phase, propagation phase, triggering phase and execution phase

Worm : A network virus is know as worm. They spread continously from system to sytem. Network Viruses are Difficult to remove.

Bacteria: The bacteria are programmes that do not explicitly demage any file. They replicate or make a large number of copies of rheir own occupy the processor capacity to block the use by the user.

Brain Virus: Brain Virus Was First Virus Developed by the two Pakistani Brothers.

What Is a Modem? What is electronic Mail?

Modem : (Modulator-demodulator) Is a device That Links Computers over telephones line. it Convert digital signals from a computer into analogue(continous) signals on a telecommunication network and vice versa

Electronic mail : Electronic mail (E-mail) Is the information directed to specific users. screens or held in computer mail box for access by users who type in codes information held on a bulletin board can be accessed by any user
