Relationship between Computer Hardware and software

• Computer Hardware and application are mutually stylish on each and every different. Both of them have to work together to make a computer produce a priceless output.
• Application cannot be utilized with out helping Computer hardware.
• Computer Hardware with out set of programs to function upon are not able to be utilized and is vain.
• To get a detailed job done on the pc, vital software will have to be loaded into the hardware
• Computer Hardware is a one-time expense.
• Software progress is very luxurious and is a carrying on with fee.
• One of a kind program functions can also be loaded on a hardware to run distinct jobs.
• A program acts as an interface between the user and the hardware.
• If hardware is the ‘coronary heart’ of a computer approach, then application is its ‘soul’. Each are complimentary to each other.

  5.       Bitmaps and Vectors - the Difference
  
  

  Bitmap:-	Vector:-
  Bitmap images are resolution dependent  (pixel )	Vector images are made up of many individual, scalable objects. These objects are defined by mathematical equations rather than pixels, so they always render at the highest quality.

                 

  Common bitmap formats include: • BMP • GIF • JPEG, JPG • PNG • PCX • TIFF • PSD (Adobe Photoshop) Popular bitmap editing programs are: • Microsoft Paint • Adobe Photoshop • Corel Photo-Paint

  Common vector formats include: • AI (Adobe Illustrator) • CDR (CorelDRAW) • CMX (Corel Exchange) • SVG (scalable vector graphics) • CGM Computer Graphics Metafile • DXF AutoCAD • WMF Windows Metafile Popular vector drawing programs are: • Autocad • Adobe Illustrator • CorelDRAW

  
  
  
  
  
  6.       Resolution refers to the number of pixels in an image
