How to UTP Cabling


UTP, stands for “unshielded twisted pair”. Called unshielded because less resistant to electromagnetic interference. And called twisted pair as it includes couples who are prepared spiral cable berlilitan alias each other. There are 5 categories of UTP cable. From category 1 to category 5. For the famous computer network is a category 3 and category 5.
Category 3 can be used for data transmission up to 10 mbps, while category 5 to 100 mbps. If only create such a network in your office or campus computer or internet cafe, yes the most efficient use of the category 3. That was more than enough.
As far as the writer there are many brands on the market, it’s just that stubborn and relatively cheap famous brand is Belden – Made in USA. If you want a cheaper and use a lot, then just buy one box, approximately 150 meters in length. Do not forget to buy the connectors. Shaped like a telephone socket connector only bigger.
Another very important, you must have a special pliers for installing the connector to the UTP cable, fancy term is “the crimp tool.” This tool is useful to ‘turn off’ or ‘planting’ connector to the UTP cable. So once already in the ‘tang’, then it can not be removed again connectors. And if you want a more OK, I’ll not bear the same buy a LAN tester. You can buy a brand from Taiwan just so much cheaper. Shaped like a box and there are LED lights his eight pairs and can-blink-resistant.
OK now you ready tools, the authors start. In general, the UTP cabling are of two types, namely straight and cross type. Type is called straight because each cable corresponding numbers were 1-1 8, directly. While called a cross because there are crosses on the composition of the cord. Confused?
OK! For the straight type is used to connect the cable from the client to the hub. While for the type of cross is to the client directly connected to the client (cpu to cpu) or also from hub to hub.
We first discuss the types of straight 
This type is most easily made. Why? Because the direct correspondence 1-1. Standard sequence like this: 2 orange – green 1 – 2 blue – green 1 – 2 brown. 2 orange here meaning the same pair of young orange dark orange and so on. But do not come standard staining was also really no problem. The important sequence of the cord. For example the first end of the first order of pins young orange, the other end of the first order of the pins must also be young orange, so between the end connect to each other. Actually, not all pins are used.
The important thing is the pin numbers 1,2,3 and 6. So for example which are connected only pins 1,2,3 and 6 while the other pins are not installed, no problem. For more details, please see the picture below is the author of a book of photographs.
Who left the order for the type of correspondence straight, the right of the cross
Time will install it, then cut the tip of the cord, then stacking the cord then flattened with a knife cutting at the crimp tool available. Andak not have to bother to let go at the end of the cable insulation, because when you insert the cable into the connector then pressed (pressed) using a crimp tool, when it was actually there at the connector pins that penetrate down to the wire. Consider, for emphasis (pressing) a hard, hard sometimes because if you do not pin it does not penetrate into the cable insulation. If you have then you test using the LAN tester. Insert the tip ends of the wires to the device, then turn it on, if the LED lights on the LAN tester that lights up everything, from number 1 to 8 means that you have been successful. If there’s one that does not work means the possibility of the pin numbers are no problem. The easiest way is that you press (press), again using the pliers. Possibility of the pin has not been transparent. If you press but still does not connect, then try to check the correspondence between pins 1-1 or have not already. If it was true and still fail, then indeed you are not lucky. Repeat again until it works.

Change Startbutton text


Hacking the Start button
This works on XP Pro Build 2600 (The final verison),
and it should work on all other versions as well.

ALWAYS BACKUP EVERYTHING YOU EDIT OR DELETE.
I'M NOT RESPONSIBLE IF YOU MESS YOUR COMPUTER
UP BY DOING THIS HACK. DO IT AT YOUR OWN RISK.

First off, you need to download a program called
Resource Hacker. It's kinda like a hex editor,
it allows you to change bitmaps, text, ect.
in program files.
Windows XP has a feature called Windows File Protection.
This feature stops you from changing important system files,
that could leave your operating system, non-fuctional.
The file that we need to edit, Explorer.exe,
is protected by Windows File Protection. What we need to do,
is make Explorer.exe not part of Windows File Protection.
Once we do that, we will be able to edit
Explorer.exe when we want, and as much as we want.

Click on your start button -> then Run and type in
"%systemroot%system32Restore" without the quotes.
Now you should see the file filelist.xml.
What? You don't see it? We can fix that.
In windows explorer click Tools->Folder Options->
View and scroll down where it says Hide protected
operating system files (recommend) and un-check it.
Also click where it says Show hidden files and folders,
and uncheck Hide extensions for unknown file types. Lastly, hit Ok.
Now, you should see filelist.xml listed. Right click on filelist.xml
and click properties. Uncheck where it says Read Only and then click OK.
Good, now we can edit filelist.xml. Right click filelist.xml again,
and click Open with then on Notepad.
The file should now be opened in notepad.
This is where Windows File Protection looks to see if it needs to
protect a file or not. Where it says:

%windir%system.ini

add this a line above it:

%sytemroot%explorer.exe

Now, click file -> Save. (NOT Save as)

Next click on your start menu-> run and type in
"%systemroot%system32dllcache" without the quotes.
In this DIR, find and delete Explorer.exe.
This is a backup copy of Explorer.exe and windows might
try and replace this copy with your hacked copy if it isn't deleted.
After you delete it, windows will popup a message, just hit cancel then yes.

We should now be able to edit Explorer.exe as we wish. Run Resource Hacker
(The file you downloaded earlier). In ResHacker click File->
Open and open Explorer.exe. Mine is located in C:winntexplorer.exe
yours maybe located in C:windowsexplorer.exe. Once you have it open you should see something like this:




To change the "Start" text on the start button go to:
String Table -> 37 -> 1033. To the right, you should see the words "start".
You can change this to anything you want. I changed mine to LinuXProX.
Next, hit the Compile Script button above.
Now, go to String Table -> 38 -> 1033. Again, to the right you should see "Start".
Change this to the same thing you changed the other one to, mine says LinuXProX. Next,
hit the Compile Script button above. Now, if you just wanted to change the start button text,
you can skip down to "Saving".

Don't you hate the little icon (image) on the start button? Well,
we change it, and it's very easy to do.
In ResHacker, go to Bitmap -> 143 -> 1033.
You should see the window that is on the start button to the right.
To change it, you Action -> Replace bitmap -> Open with new bitmap.
Now you can make your own image, If you want to make your own,
it has to be 25x20 and 16 million colors. Once you found the bitmap you want to use,
just click open then click Replace.


Lastly, to change the Start Menu border, go to Bitmap -> 167 -> 1033.
(This is Windows XP Pro. If you have Home Editon It's Bitmap->166->1033) Click Action ->
Replace bitmap -> and where it says Select bitmap to replace:
scroll down to 167 or 166 if you have XP Home Editon.
Now, click Open file with new bitmap and find the image you want to replace it with,
click open, then on Replace.
It's best to make your own image on this one,
I just edited the default bitmap since I'm not that great with graphics.
 Maybe someone will make me a cool one, and send to me. *Hint* *Hint* :)
If you want to edit the default image, or use it as a template,
just right click on the Windows XP Pro/Home image and click copy.
Now, open up your favorite graphics program, I have Jasc Paint Shop Pro,
and hit CTRL-V. That should paste the image from your clipboard to your graphics program.
If you want to make your own, it has to be 21x233 16 million colors. Once your down editing,
just save it as a .bmp somewhere on your drive. I saved mine to C: est.bmp :).


Additional Comments:

-Saving

There are alot of bitmaps in Explorer.exe along with Text Strings, that you can change,
just hack around in it and see what you can find. If you try and save Explorer.exe it wont save.
Why? Because Explorer.exe is currently running on your computer and it can't save it
while the program is running. So how am I suppose to save it? Well, there are a few ways to do that.
One, you could save your hacked version to floppy, boot to dos and copy it.
Two, if you dual boot you could save it from within another operating system.
Or three, the easiest and fastest way, save it without rebooting, and here is how:

Hit CTRL-ALT-DEL and Windows Task Manager should popup.
Click on the processes tab and find Explorer.exe, and click it once.
Now, hit the end process button at the bottom (Make sure you don't have any other programs open).
Your taskbar at the bottom of the screen should disappear.
Hold ALT then click tab while holding ALT, then let off the ALT.
Keep doing this until Resource Hacker comes in to view.
We can now save Explorer.exe because it is not running. Click File-> Save as->
and find Explorer.exe again, mine is located in C:winnt.
It will ask you if you want to overwrite, just click yes.
Now, ALT-TAB back to Windows Task Manager and click on File -> New Task ->
in the black type in Explorer.exe, or type in the full path to explorer like:
C:winntexplorer.exe. If you did everything correctly,
you should see your new image and name on the start button, along with the start menu border.

What is a FTP Client?

What is a FTP Client? As a website or blog owner, knowing how to use a FTP client (FTP software) is a useful skill. Instead of relying on your WYSWYG (What you see what you get) software or the interface of your blogging software to upload files, images and other content to your webspace you can use a FTP client and be in full control. What Does FTP Stand For? FTP is the acronym for the File Transfer Protocol, a protocol for transfering files. What is FTP Software Used For? FTP software (or FTP client) is used to copy files from one computer to another over the Internet. Your FTP software connects to another computer connected to the Internet using a file host name, user name and password when we are talking about using it to upload (or download) files and content for your website or blog. FTP Security Regular FTP transfers are not secure. The data sent over the Internet is not encrypted therefore the file, user name, password and commands sent can be read/seen by a packet sniffer (capture) piece of software surfing the net to find such information. For better security use a FTPS connection. Using a FTP Client First of all, you have to download a FTP program. FTP clients can either be free or a paid version. Comparison of FTP Client Software at Wikipedia has a list sorted by free, freeware,freeware and payware, payware and operating system. You will need the FTP information from your web hosting firm. Try and get the secure FTP information. Once you have installed the FTP client on your computer you need to set it up for the site you wish to FTP the files to. Start the FTP client and enter: 1. A profile name. The profile name can be anything you want. Make it something that will make sense to you later if you will be using the FTP software for more than one site. 2. The host name. The host name will be given to you by your web hosting compay. It can be an IP address (123.123.123.123) or your domain name with ftp in front (ftp.mydomain.com). 3. Your FTP user name. Depending on how your web hosting handles FTP, you could have been automatically assigned a FTP user name or you may have to create a FTP account yourself. 4. Your FTP password. For security reasons, this should be different from your web hosting account login password. If your web hosting company has setup the FTP account with the same password as your main login, change it to something else. Use PCTools Secure Password Generator to create a secure password. Make sure you record it somewhere for safekeeping! Also for security reasons, do not save the password to the software. If you do, anyone that gains access to your computer can upload/download or otherwise mess up your site. Don’t worry, you will soon remember the password to enter each time you use the FTP client. 5. Location of files on your computer. To make things easier each time you use the FTP client, enter the path on your computer to the folder that contains your website or blog’s files. 6. Location of the folder on the web server. Like the location of the files on your computer, if you enter the path to the correct location on the web server for your site you won’t have to navigate the path next time you use the FTP client. Using a FTP client to transfer your website or blog files is a skill each site owner should learn. You can also use your FTP client software to backup your site. You have a backup, right?

Definition of 3G:


3G is the third generation of wireless technologies. It comes with enhancements over previous
 wireless technologies, like high-speed transmission, advanced multimedia access and global
 roaming. 3G is mostly used with mobile phones and handsets as a means to connect the phone
 to the Internet or other IP networks in order to make voice and video calls, to download
and upload data and to surf the net.
                                               
3G has the following enhancements over 2.5G and previous networks:
  • Several times higher data speed;
  • Enhanced audio and video streaming;
  • Video-conferencing support;
  • Web and WAP browsing at higher speeds;
  • IPTV (TV through the Internet) support.
3G Technical Specifications:
The transfer rate for 3G networks is between 128 and 144 kbps (kilobits per second)
for devices that are moving fast and 384 kbps for slow ones(like for pedestrians).
For fixed wirelessLANs, the speed goes beyond 2 Mbps.
3G is a set of technologies and standards that include W-CDMA,
WLAN and cellular radio, among others.
3G follows a pattern of G's that started in the early 1990's by the ITU.
The pattern is actually a wireless initiative called the IMT-2000
(International Mobile Communications 2000). 3G therefore comes
 just after 2G and 2.5G, the second generation technologies.
2G technologies include, among others, the Global System for
Mobile (GSM)
 - the famous mobile phone technology we use today.
 2.5G brings standards that are midway between 2G and 3G,
 including the General Packet Radio Service (GPRS),
Enhanced Data rates for GSM Evolution (EDGE),
Universal Mobile Telecommunications System (UMTS) etc.
What is Required for Using 3G?:
The first thing you require is a device (e.g. a mobile phone)
 that is 3G compatible. This is where the name 3G phone comes
 from - a phone that has 3G functionality; nothing to do with the
 number of cameras or the memory it has. An example is the iPhone 3G.
3G phones commonly have two cameras since the technology
allows the user to have video calls, for which a user-facing
camera is required for capturing him/her.
Unlike with Wi-Fi which you can get for free in hotspots, you
 need to be subscribed to a service provider to get 3G network
connectivity. We often call this kind of service a data plan or network plan.
Your device is connected to the 3G network through its SIM card
 (in the case of a mobile phone) or its 3G data card
(which can be of different types: USB, PCMCIA etc.),
 which are both generally provided/sold by the service provider.
 Through that, you get connected to the Internet whenever you are
within a 3G network. Even if you are not in one, you can still use
 2G or 2.5G services provided by the service provider.
                                      
What Does 3G Cost?:
3G is not very cheap, but it is worthwhile for users that
 need connectivity on the move. Some providers offer
it within a somewhat costly package, but most of them have
plans where the user pays for the amount of data transferred
. This is because the technology is packet-based. For example,
there are service plans where there is
 a flat rate for the first Gigabyte of data transferred,
and a per minute cost for each additional Megabyte.
3G and Voice:
Wireless technologies are a way for mobile users to make free or
 cheap calls worldwide and save a lot of money
due to the latest telephony applications and services.
3G networks have the advantage of being available on the
 move, unlike Wi-Fi, which is limited to a few meters
 around the emitting router. So, a user with a 3G phone and
a 3G data plan is well-equipped for making free mobile calls.
She will only have to download one of the free
 applications and install on
her mobile phone and start making calls. Here are examples of mobile VoIP services.
Using VoIP is a great way of saving money on phone calls. Here's how
