Passion for Programming

Computer virus is code in a host which has its source which is external. Its main intention is to gain resources in host which is not legitimate in normal case. There is a fancy expansion for VIRUS i.e Vital Information Retrieval Under  Siege. Mark Ludwig in his book titled “The Gaint Black Book of Computer Virus” expresses that all the virus can be broadly classified into three types. They are: i)Over writing ii)Companion iii)Parasitic. All the malicious code will exhibit either or all of the above mentioned basic behavior. To play with code ,especially virus it is really essential to get closer to the machine. In the sense, it is necessary to learn the assembly language(May be 8086). And this is it for intro!  Hope that I would find time to post further details in the upcoming posts.

All latest Motherboards today, 486/ Pentium / Pentium Pro etc.,ensure that upgrades are easily obtained by incorporating the system BIOS in a FLASH Memory component. With FLASH BIOS, there is no need to replace an EPROM component. Once downloaded, the upgrade utility fits on a floppy disc allowing the user to save, verify and update the system BIOS. A hard drive or a network drive can also be used to run the newer upgrade utilities. However, memory managers can not be installed while upgrading. Most pre-Pentium motherboards do not have a Flash BIOS. The following instructions therefore do not apply to these boards. If your motherboard does not have a Flash BIOS (EEPROM) you will need to use an EPROM programmer to re-program the BIOS chip. See your dealer for more information about this. Please read the following instructions in full before starting a Flash BIOS upgrade: A. Create a Bootable Floppy (in DOS) •With a non-formatted disk, type the following: format a:/s •If us...

Fatal error: the system has become unstable or is busy," it says. "Enter to return to Windows or press Control-Alt-Delete to restart your computer. If you do this you will lose any unsaved information in all open applications." You have just been struck by the Blue Screen of Death. Anyone who uses Mcft Windows will be familiar with this. What can you do? More importantly, how can you prevent it happening? 1 Hardware conflict The number one reason why Windows crashes is hardware conflict. Each hardware device communicates to other devices through an interrupt request channel (IRQ). These are supposed to be unique for each device. For example, a printer usually connects internally on IRQ 7. The keyboard usually uses IRQ 1 and the floppy disk drive IRQ 6. Each device will try to hog a single IRQ for itself. If there are a lot of devices, or if they are not installed properly, two of them may end up sharing the same IRQ number. When the user tries to use both devic...

 As the size of hardrives increase, more people are using partitions to seperate and store groups of files. XP uses the C:\Program Files directory as the default base directory into which new programs are installed. However, you can change the default installation drive and/ or directory by using a Registry hack. Run the Registry Editor (regedit)and go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion Look for the value named ProgramFilesDir. by default,this value will be C:\Program Files. Edit the value to any valid drive or folder and XP will use that new location as the default installation directory for new programs.

Getting used to using your keyboard exclusively and leaving your mouse behind will make you much more efficient at performing any task on any Windows system. I use the following keyboard shortcuts every day: Windows key + R = Run menu This is usually followed by: cmd = Command Prompt iexplore + "web address" = Internet Explorer compmgmt.msc = Computer Management dhcpmgmt.msc = DHCP Management dnsmgmt.msc = DNS Management services.msc = Services eventvwr = Event Viewer dsa.msc = Active Directory Users and Computers dssite.msc = Active Directory Sites and Services Windows key + E = Explorer ALT + Tab = Switch between windows ALT, Space, X = Maximize window CTRL + Shift + Esc = Task Manager Windows key + Break = System properties Windows key + F = Search Windows key + D = Hide/Display all windows CTRL + C = copy CTRL + X = cut CTRL + V = paste Also don't forget about the "Right-click" key next to the right Windows key on your keybo...
