I was a CSR(Customer Support representative) few years back. I had a lot of funny events that happened when i was on call and when i was supporting one of the leading Desktop and Laptop products company. Have been struggling with people, to make them understand very simple things. Few months down the lane, i was promoted as senior support engineer. Where i handled a small team of support engineers. I had a guy in my team, who was trying to explain the customer about restarting the computer. He tried many ways to point out the reset button, which is at the front of the big box near to the monitor(that is how, we call the cpu. So that customers understand). In the process of explaining it to the customer, accidently our support guy restarted his own CPU.
There are few other funny things that has happened when providing support. Here are few simliar things that are listed in this site.

Google video download
DEXTER'S BLOG'S
Many of us are really eager to download the movies/clips that we see in the Google videos.
Atlast.....we got some solution to download the clips from the google videos.
A lot of Web sites are providing scripts to download the videos. But, most of us do not go with that and we need some easier ways to get the videos.
Let me not keep you reading.....take a quick look at the below things and start downloading the clips.
Copy the link of the video you like to download and paste it in the text box that is provided in the below link and click on "Download Video".
This will start getting the exact link from the google and provide us the direct link to download the video in ".avi" format. After clicking on the download video button it takes some time to get the exact link and it provides the link, which needs to be viewed by scrolling the page.
Here is the link:
http://downloadgooglevideo.cjb.net/
Note:
Sometimes, if the video file is located in different server or if there is heavy traffic, we might not get the link to download the video file.

Components for wired/wireless network
DEXTER'S BLOG'S
http://www.pcbuyerbeware.co.uk/Networking.htm
networking two or more computers should not be confused with the Dial-Up networking that is used to make a dial-up modem connect to the Internet or send faxes, etc. For this, Windows 95, Windows 98, Windows Me (collectively called Windows 9x in this article), and Windows XP systems use a software Dial-Up Adapter that is installed under Network adapters in the Device Manager. If you install a hardware network interface card (NIC) it will also be listed there as a device.
You can enable a setting under Networks/Network Connections in the Control Panel that places an icon for the Dial-Up Adapter (Windows 9x) or the 1394 Net Adapter/1394 Connection (Windows XP/SP2) in the System Tray/Notification Area. If you hold the mouse over the icon, the connection details appear. If you right-click on the icon, you are presented with several options, which depend on the version of Windows being used.
Permanently stored within every network interface card (NIC) or wireless network adapter is a unique 48-bit binary number called the MAC (Media Access Control) Address. And it is by this MAC address that each NIC or adapter card is identified within a local area network (LAN). Indeed, it was because each NIC's MAC address uniquely identifies it in the log files of Internet servers that the writer of the infamous "I love you" virus was traced and brought to justice.
To find out what the MAC address is for a network card or adapter in Windows 98 or Windows Me, enter winipcfg in the Start => Run box. The MAC address is listed as the Adapter Address in the window that presents itself. In Windows XP, enter cmd in the Start => Run box and then enter ipconfig /all at the command prompt. The MAC address is listed as its Physical Address. You may need to know the MAC address in order to set up a wireless network that shares an Internet connection.
See this page of the Build Your Own PC article for information on Windows Dial-Up networking, and how to install and configure a 33.6K or 56K dial-up modem.
networking two or more home computers is nowhere nearly as difficult as it used to be before the advent of Windows 95 in 1995 - even if it is a wireless network. In fact, it is now a relatively simple procedure to set up a peer-to-peer (wired or wireless) home network.
The alternative is to create a server-based network that uses one computer as the server, the resources of which are used to serve client computers. The client computers do not have to have any software other than the client network operating system installed on them. They take everything they need to use from the server over the network. But you do not need a server-based network to play network games, or use Microsoft's Internet Connection Sharing. This is just as well, because server and client networking requires the use of the expensive Windows NT, Windows 2000, Windows XP Pro, the very much cheaper open-source Linux, and other server-client operating systems.
The Windows 9x versions of Windows (95/98/Me) provide you with all of the software required to set up a peer-to-peer (P2P) network of 2 to 10 computers that allows file, printer, and Internet access sharing between all of the computers connected to the network.
You can purchase third-party alternatives, but Internet Connection Sharing (ICS) is the free software that was introduced with Windows 98 Second Edition, so, unless your make use of third-party software, you will have to have that version of Windows (or a more recent version) running on the computer with the modem that is connected to the Internet so that it can use its ICS software to share an Internet connection with the other Windows 9x computers on the network.
All of the computers running Windows 9x must be individually configured as ICS clients. However, with Windows XP, you can use the Network Setup Wizard to enable ICS on a single computer (running Windows XP), which has an option to create a Network Setup Disk that can then be used to enable it on the other Windows XP computers on the network.
The best solution to sharing an Internet connection over a network is to use a separate hardware router, often known as a "gateway", that links the computers together and connects to a broadband ADSL or cable modem, which, in turn, is constantly connected to the Internet Service Provider... There is more information on routers later on in this article.
Here is what Microsoft says about ICS in the Windows 98 SE Help files.
"Windows 98 now provides users the ability to share one Internet connection with multiple computers on your home network. One computer, the Connection Sharing computer, communicates with the Internet. Requests from other computers on your home network are routed to the Internet through the Connection Sharing computer. You can also configure Internet Connection Sharing to allow users on the Internet to reach Web, e-mail, and game servers that are on your home network."
Instructions on how to set up and use ICS are also provided in the Help files. It is a relatively straightforward process.
I will provide the basic information about home networking here, but, since there are numerous sites that provide excellent illustrated tutorials on how to install and configure a home network or Local Area Network (LAN), I will provide the links to some of those site at the end of this article instead of attempting to provide that kind of information myself.
By the way, a Wide Area Network (WAN) is the kind of network that libraries, the Government, the banks, and other businesses use to link their computers over a wide area, such as over the whole country, or internationally. The Internet itself is a giant WAN that spans the world.

Difference between router,switch and hub
DEXTER'S BLOG'S
A router is a more sophisticated network device than either a switch or a hub. Like hubs and switches, network routers are typically small, box-like pieces of equipment that multiple computers can connect to. Each features a number of "ports" the front or back that provide the connection points for these computers, a connection for electric power, and a number of LED lights to display device status. While routers, hubs and switches all share similiar physical appearance, routers differ substantially in their inner workings.
A switch is a small hardware device that joins multiple computers together within one local area network (LAN). Technically, network switches operate at layer two (Data Link Layer) of the OSI model. Network switches appear nearly identical to network hubs, but a switch generally contains more "intelligence" (and a slightly higher price tag) than a hub. Unlike hubs, network switches are capable of inspecting data packets as they are received, determining the source and destination device of that packet, and forwarding it appropriately. By delivering each message only to the connected device it was intended for, a network switch conserves network bandwidth and offers generally better performance than a hub.
A Hubis a small, simple, inexpensive network device that joins multiple computers together.

Most hubs manufactured today support the Ethernet standard. Non-Ethernet hubs (Token Ring, for example) also exist, but Ethernet is always used in home networking. Technically speaking, hubs operate as Layer 2 devices in the OSI model.
To join a group of computers with an Ethernet hub, one connects an Ethernet cable (that has an RJ-45 connector attached) into the hub, then connect the other end of the cable each computer's network interface card (NIC). Hubs also require external power and can be connected to other hubs, switches, or routers.
One good way to differentiate between Ethernet hubs is by the speed (data rate) they support.

Basics about wireless network
DEXTER'S BLOG'S
This blog is to brief about creating a simple wireless network:
In 1997, when the Institute of Electrical and Electronics Engineers (IEEE) created the first WLAN standard they called it 802.11. Because it could only support a maximum bandwidth of 2Mbps - far too slow for most of today's applications - ordinary 802.11 wireless products are no longer being manufactured. The next wireless incarnation was 802.11b, which supports bandwidths of up to 11Mbps, followed by the creation of 802.11g, which supports bandwidth up to 54 Mbps and signals in a regulated 5 GHz range. While 802.11g is the fastest wireless technology, is it the best for your home or business? Here is a brief synopsis of the three primary 802.11 standards:
This blog is to brief about creating a simple wireless network:
The Evolution of 802.11 wireless Technology
1997 - 802.11 - 2 MBps
1999 - 802.11a - 54 Mbps in regulated 5 GHz range. Pro: Fast access. Con: Limited range
1999- 802.11b - 11Mbps in 2.4 GHz range
2002 - 802.11g - 54 Mbps in 2.4Ghz range and is backwards compatible with 802.11b, meaning that 802.11g access points will work with 802.11b wireless network adapters and vice versa. Pro: Faster access and backwards compatibility. Con: Higher cost than 802.11b.

The next wireless incarnation was 802.11b, which supports bandwidths of up to 11Mbps, followed by the creation of 802.11g, which supports bandwidth up to 54 Mbps and signals in a regulated 5 GHz range. While 802.11g is the fastest wireless technology, is it the best for your home or business? Here is a brief synopsis of the three primary 802.11 standards:
- 1. 802.11b - This technology supports bandwidth up to 11MBps, which is comparable to the speeds of traditional Ethernets. 802.11b uses the same 2.4GHz radio signaling as the original 802.11 standard. Because it is an unregulated frequency, 802.11b devices run the risk of incurring interference from appliances that use the same 2.4 GHz range, such as microwaves and cordless phones. However, if you install 802.11b devices out of range of other appliances, you can avoid the interference. Some manufacturers prefer using unregulated frequencies, such as 802.11b to lower their production costs. On the negative side, 802.11b is relatively slow and supports fewer simultaneous users.
- 802.11a - IEEE created 802.11a at the same time it made 802.11b. 802.11a supports bandwidth up to 54 Mbps and signals in a regulated 5 GHz range. This higher frequency limits the range of 802.11a in comparison to 802.11b, and due to its higher cost it's used primarily in the business sector rather than in homes. 802.11a's higher frequency also causes its signals to have difficulty penetrating walls and other obstructions. Because they utilize different frequencies, 802.11a and 802.11b devices are incompatible with each other.
- 802.11g - This technology supports of up to 54 Mbps, uses the 2.4 GHz frequency and is backwards compatible with 802.11b devices. 802.11g supports more simultaneous users, offers the best signal range and is not easily obstructed. The disadvantages of 802.11g is higher cost and possible interference with appliances on the unregulated signal frequency.

Is your DSL good
DEXTER'S BLOG'S
A general rule of thumb for determining whether or not you have a good broadband connection is whether or not you are getting at least 80% of the maximum possible speed you could. There is a built in 'loss' due to overhead information that must be transmitted and a few other factors that immediately eat up about 13% of your bandwidth (speed). That means that the absolute best in a perfect setup would be 87% of your theoretical maximum. With other factors thrown in, the 80% rule of thumb was developed. Now, how to apply it.
As one example, lets assume you have a 1.5/256 DSL connection. This means that the best you can ever do is to get 1500kbps (kilobits per second) as a download speed and 256kpbs upload. But at least 13% of that is going away for the overhead. 80% of 1500 is 1200kbps, and 80% of 256 is 204.8kbps. So if you have a 1.5/256 line and are getting speds of 1200/204 or better, then you have a 'good' connection.
If you are getting less than these numbers, the DSLR Tweaks forum is a good place to go to start optimizing the portion of the system that can help with these numbers.
A few things to keep in mind: 1) You can only 'tweak' to improve your download speed and hopefully your upload speed will rise along with it; 2) It is hard to apply the 80% rule to an uncapped Cable connection where no upper limit for speed is stated; 3) no 'tweaks' are available to improve Ping (latency) times - that is a separate issue.

C is generally acknowledged as one of the best programming languages
available. It has a rather long story, and has been used for building a lot of the "BIG" programs in existence. Experienced C-programmers might not be able to find much of value in this textfile, but programmers experienced in other programming languages (like QBASIC or Pascal) might find this text useful for upgrading to C.

Escape from ATM robbers
DEXTER'S BLOG'S
Here is the way to escape from a robber, when you are at ATM......
If you should ever be forced by a robber to withdraw money from an ATM Machine, you can notify the police by entering your Pin # in reverse.
For example if your pin number is 1234 then you would put in 4321. The ATM recognizes that your pin number is backwards from the ATM card you placed in the machine.
The machine will still give you the money you requested, but unknown to the robber, the police will be immediately dispatched to help you. This information was recently broadcasted on TV and it states that it is seldom used because people don't know it exists.
This was forward.....
