Page 15 :HTTP Error 400 Bad request

Introduction

The Web server (running the Web site) thinks that the data stream sent by the client  was 'malformed'

i.e. did not respect the HTTP protocol completely.

So the Web server was unable to understand the request and process it.

400 errors in the HTTP cycle

Any client  goes through the following cycle:

• Obtain an IP address from the IP name of the site  This lookup (conversion of IP name to IP address) is provided by domain name servers (DNSs).
• Open an IP socket connection to that IP address.
• Write an HTTP data stream through the socket.
• Receive an HTTP data stream back from the Web server response. This data stream contains status codes whose values are determined by the HTTP protocol. Parse this data stream for status codes and other useful information.

Fixing 400 errors - general

There is a low-level problem in the client or the Web server or both. 95% of the time this is because of a problem on the client system
e.g. there is something unstable on your PC running the Web browser.

• Try to browser again in three times to make sure that error
• What has changed since you started getting the HTTP 400 problem ?. In general terms, think about what has changed on your PC since you first started seeing the problem. This may cover any of the items mentioned above.

• How stable is your Internet connection ?.You can  try to check that the Web site you are actually visiting is the one you think you are visiting. For example, you may have a DNS problem. You can check this using a ‘ping’ test. A DNS problem may be caused by your ISP or may be on your own system e.g. in a ‘hosts’ file.

• Is your PC secure ?. If your PC is not well-protected, then all kinds of problems may occur - including HTTP 400 errors. If you run Windows, stay uptodate with automatic security updates from Microsoft and possibly consider getting a registry cleaner. Always have good anti-virus and spyware protection. Invest in a hardware firewall if you can afford one. Be sensible surfing the Web - block pop-up windows and avoid bad sites. If your PC not secure then Web traffic out from your PC to the Internet may be secretly corrupted by malware (spyware, viruses, etc.).
• Are you installed web-based software ?. Some social networking and games sites ask you to download and run software on your PC so you can interact with other people on the Internet directly (without using your Web browser). This software, if badly written or even criminal, can corrupt all HTTP traffic from your PC. At bad action, you may have to reinstall your operating system again (possibly losing all your personal data on your PC if you do not have backup).may be defective. Try to find an upgrade or security fix for the problem browser. 
• If you recently changed some configuration options in the problem browser, reversing the change to see if that helps to fix this problem.
• Do you get the error on big Web sites ?. If you get the problem on quite a small site, visit some of the bigger sites like Amazon, Ebay, Google, Microsoft and Yahoo. If you get the problem only on small sites, it indicates a problem with only those sites or the traffic from your PC to those sites.
• Do you get the error on simple URLs ?. If you get a problem with a long complicated URL (such as http://www.xxx.com?PHPrequest=643&value=dres&cookies=No) but not with a shorter simpler URL for the same site (such as http://www.xxx.com), this can indicate a problem with the Web server on the site you are trying to visit. This is not conclusive evidence, but is a good starting point. Contact the owners of the Web site and describe the problem to them. You may find for example the problem occurs with POST methods (you are both submitting data to the Web site and retrieving data from the Web site), but not with GET methods (you are only retrieving data from the Web site).
• Do you have a cache problem ?. clearing your cookies, browser cache and browsing history in your Web browser. Disable or remove any third-party cache or ‘web accelerator’ software you installed. Then try rebooting your PC . If this action  not fix the error, but at least may eliminate any problem due to settings on your PC.

page 14 : internet port listing

 What is port

The  IP address would correspond to the street address of the building and the ports would correspond to room numbers.
 In fact, the standard form of an URL ( the human-friendly equivalent of the numerical IP address) has a section for designating a port. 
 The port number is almost never necessary in an URL, however, since port number 80 is assigned by convention to the Internet protocol http.

Ports are numbered from 0 to 65536. 

However, port numbers are not assigned haphazardly but conform to standards from the Internet Assigned Numbers Authority (IANA). 

Ports 0-1023 (designated as "well known ports") are assigned by IANA and are generally reserved for system processes. 

For example,the protocol http is assigned port 80. 

Ports 1024- 49151 are called "registered ports"; their assignments are coordinated and approved by IANA.

A list of these is published so that conflicts in the use of ports do not arise. (Malware writers, of course, do not observe these rules.) The remaining ports 49152- 65535 are called "dynamic" and/or "private ports". Some common processes and their standard port assignments are given in the table below.

here the port list for internet port

* 21 (FTP)

* 22 (SSH)

* 23 (TELNET)

* 25 (SMTP)

* 53 (DNS)

* 80 (HTTP)

* 110 (POP3)

Part 5 : Knowing your computer (Display adapter)

Display adapter  or Graphics array

here the list of the extended of graphic array from 1980 until 1990, and now you can see many feature in this card,this artice is about the type of your display adapter, but if you see in device manager is alway themanufacture type brand and the chipset model. But in here here we discussed about a general display adapter, and 

about chipset and model we will release other article

Here the list of Graphics array (External VGA), but many computer pc manufacture have internal VGA, so if you buying a computer desktop, you have two choice use internal Graphics array (VGA internal) or you want to upgrade in external VGA 

 

CGA

At the beginning of the 1980s, this was typically used to display Lotus 1-2-3 spreadsheets in high-resolution text on a monochrome display and associated graphics on a low-resolution CGA display simultaneously

XGA

 The eXtended Graphics Array (XGA) supports all 8514/A modes plus a 800×600 16-bit RGB Highcolor mode, with 65,536 simultaneous colors on screen

MCGA and VGA

The Multicolor Graphics Array (MCGA),  Video Graphics Array (VGA) used a 6-bits per channel, 64 levels Digital-to-Analog Converter (DAC) to give an 18-bit RGB palette (262,144 colors), from which can be selected any two (in MCGA 640×480 graphic mode), 16 (in VGA 320×200, 640×200, 640×350 and 640×480 graphic modes) or 256 (in MCGA 320×200 graphic mode) at a time.^[3] They both provided full compatibility with CGA modes, while VGA included all the EGA modes as well as the MCGA modes.

 ...................................................................................................................................................................

In this times, all the manufacture of the computer do not produce again the type of CGA,XGA,MCGA.

Super VGA (SVGA)

Enhanced clones of the IBM VGA, known as Super VGA (SVGA), support 256 simultaneous colors in 640×480 and higher pixel resolutions (800×600, 1024×768) in both 16 and 256 picked colors from the VGA 18-bit RGB palette, depending on the model and the manufacturer. Also, some SVGA cards support 15- and 16-bit RGB Highcolor modes, with 32,768 or 65,536 simultaneous colors on screen in 640×480 and higher resolutions. Some later models reach the 24-bit RGB True color modes.

There is Three model in VGA Card

See our  picture  in the right side set your mouse in the images and you can see what type of the vga card,

• PCI, standar video graphic
• AGP,  games and video
• PC-xpress for games 

Part 4 : Knowing your computer (LAN)

LOCAL AREA NETWORK

May be you like to make your own server and small link in your office ( in 2-4 computer)
also see our page "Step instal server windows 2008" and Zoopy

 Now, describe the LAN

A local area network (LAN)

 is a computer network that interconnects computers in a limited area such as a home, school, computer laboratory, or office building. Computer network is always been said as a network, is a collection of hardware components and computers interconnected by communication channels that allow sharing of resources and information

This in internal LAN card (Only UTP)

Open the CPU casing and,

plug in your motherboard,

Close the CPU casing,

Running the OS windows

and then instaled the driver, but  for some OS windows there is no need to instal the driver, because the windows have the back up driver

External LAN (USB to UTP)

Another choice to make your LAN, it is very symple you only need plug the USB connection from a desktop PC or Laptop.

BNC and UTP

This is another type of LAN card with have the slot of BNC and UTP...

Now you can figure it out, which model that you want to use... 

Wait our article about motherboard..

and you can use the internal LAN card, and BNC-UTP.
