How To change Ip address?

Introduction:-
Changing the ip address of a computer refers to spoofing ip address. actualy now you can not spoof your ip address because when you spoof your ip address and send the message on the network then the gateway from which your message passess to the server will not except your request because this gateway except request only from a computer that is under its range and because you have changed your ip so you are no more in its range therefore you will not be able to surf net. hence we tunnel through proxy to get ip address of proxy server and surf net with different ip address.
In tunneling through proxy or using proxy server our request is first send to the proxy server which then send this request to server and after proxy server get's the result of this request it send this result to our computer.
there are many site which u can use for surfing site like www.browser9.com where u can put the name of site which u want's to surf. there is an ulternative to that and that is by using software called ultra surf which tunnel our request directly. and providing a simple and easy way to surf net without going to proxy site to visit some site.
this is very simple to operate and free to use. You can download it from here

how to upgrade bios?

Introduction:-
BIOS stands for Basic Input/Output Service. it is a type of program which is stored inside the ROM chip(kind of memory like hard disk but very less) of your motherboard. So our main aim here is to update the bios stored inside ROM Chip.
Update of motherboard ROM depends on the type of memory chip used in your PC because There are two types of ROM chips used in PCs:-
1) Mask-ROM (used on old motherboards and that cannot be updated by software)
2) Flash-ROM (on almost all motherboards, which is able to be updated by software).
and because mask-rom can not be upgraded by normal user so i am leaving this upon you and will teach update of flash-rom bios.

NOTE:-Sometimes, especially when upgrading your PC, you may need to perform a BIOS upgrade in order to update your system to accept a new hardware part or to fix a bug.

STEPS:-
1) find out motherboard manufacturer, model number and bios manufacturer of your computer. You can find it by

• viewing motherboard.

• Using the software speccy.
  

2) Now go to the download center of motherboard manufacturer site and then fill the information of your motherboard and hit enter.

NOTE:-website address of some common motherboard manufacturer's site is listed here

3) Then u will be given 2 file(most probably) one will be .bin or .rom and other will be program(.exe file) according to your bios manufacturer.

NOTE:-program can be present in your driver's CD(comes with motherboard).

4) burn a cd with file(.bin or .rom) and the program(.exe).
5) Restart your computer.
6) Now boot your computer from cd(by choosing cd as first boot disc in your bios set-up(for that press del after restart).
7) type

"program name" /?

and use appropriate option for update .

for my bios i used:-

Awdflash F:\tx98-a22.bin /SN /PY /CC /R

where,

• SN: (No Save)
• PY: (Program BIOS)
• CC: (Clear CMOS)
• R: (Restart)
  

NOTE:-

u can download the file by tying the the model no of your motherboard in google(some of the site(like softpedia) will provide u the bin or rom file.
but u must download the program to upgrade your bios using the file from the motherboard manufacturer site or from cd.

what is svchost.exe?

Introduction:-
Svchost.exe is a generic host process name for services that run from dynamic-link libraries (DLLs) in windows system.
During startup system create multiple instances of svchost.exe with each instance having some specific process that is defined in registry.

Ans) it is present in the windir/system32 directory. As it is difficult for us to see which services are running in background or are contained by svchost.exe therefore there is a command to see all the process inside it.

tasklist /svc /fi "imagename eq svchost.exe"

here,

• tasklist: it is used to display the program under task manager
  arguments:-
  
  • svc: this argument is used to see services running behind the process.
  • fi: this argument indicate which of the program you want to select. with the name inside the double quote and also "imagename eq" ahead to file name.
    

Q) How To change Process in svchost?
