BIOS

By

  1. BIOS stands for Basic Input Output System.
  2. It is is kind of OS pre- attached in the system
  3. Design to detect every I/O devices
  4. It holds basic drivers
  5. -checks all I/O devices
  6. -Loads main OS
  7. -Responsible for starting System switched on
  8. manufactured by AMI,Phonix,award,Baiostar
  9. POST error test, boots trap load,
  10. BIOS is unintrusive system.


CMOS and BIOS are two different components of the motherboard.

  1. CMOS work as storage if BIOS.
  2. A basic software program containing all BIOS is permanently stored in the ROM.
  3. every essencial holds program
  4. Tresh passing without knowinig is called intrusive.

What is manipulator in C++?

By
Answer: Manipulators are special functions that can be included in the I/O statement to alter the format parameters of a stream. Table-2 shows some important manipulator functions that are frequently used. To access these manipulators, the file < iomanip.h > should be included in program.                               Table-2               Manipulators                                                    Equivalent ios function               set...

Explanation of Graphics in C programming

By
   The header file graphics.h should be included to use graphics related built in functions. Again, the variable gDriver is an integer variable that specifies graphics driver to be used. Device drivers are small programs which talk directly to the hardware. Graphics drivers are a subset of device drivers and are applicable only in the graphics mode. The initialization of this variable to DETECT is to set another variable gMode to the highest resolution available for the detected driver.  The value of this variable gDriver may be another than DETECT (e.g. 1 for CGA, 9 for VGA.). The variable gMode is an integer that specifies initial graphics mode.       The built in function initgraph() is for graphics initialization. The syntax for this is as   initgraph(&graphics_driver, &graphics_mode, path_to_driver);   path_to_driver specifies the directory path where initgraph() looks for graphics drivers ( .BGI files). Thi...

Binary Mode of Data Files in C Programming

By
     In Binary mode of data file, the opening mode of text mode file is appended by a character ‘b’ i.e. “r” is replace by “rb” “w” is replace by “wb” “a“ is replace by “ab” “r+” is replace by “r+b” “w+” is replace by “w+b” “a+” is replaced by “a+b” The default mode is text mode. Thus when simple “r” is written as mode of opening, this is assumed as text mode. We can write “rt” in place of “r” and so on in the case of text of file. The syntax for all above mode in the case of binary mode is similar to the previous one i.e. text mode like this fptr=fopen(“data.txt”,”rb”);
