Activity 2

LIST THE 5 MOST COMMON TYPES OF COMPUTER SYSTEMS.

Personal computer: A small, single-user computer based on a microprocessor.






  








Workstation: A powerful, single-user computer. A workstation is like a personal computer, but it has a more powerful microprocessor and, in general, a higher-quality monitor.

Minicomputer: A multi-user computer capable of supporting up to hundreds of users simultaneously.   

 
 Mainframe: A powerful multi-user computer capable of supporting many hundreds or thousands of users simultaneously.

  

 


 Supercomputer: An extremely fast computer that can perform hundreds of millions of instructions per second.

IDENTIFY TWO UNIQUE FEATURES OF SUPERCOMPUTERS                 

1.  Massively Parallel Processing (MPP), is to chain together thousands of commercially available  microprocessors utilizing parallel processing techniques.
 
           

2.    Beowulf cluster, or cluster computing, employs large numbers of personal computers interconnected by a local area network and running programs written for parallel processing.

              

DESCRIBE A TYPICAL USE FOR MAINFRAME COMPUTERS

-A mainframe is usually used for critical applications and bulk data processing (for example census processing, large company payrolls).

DIFFERENTIATE WORKSTATIONS FROM PERSONAL COMPUTER

           
A workstation is a powerful, single-user computer it is like a personal computer, but it has a more powerful microprocessor and, in general, a higher-quality monitor while personal computer is a small, single-user computer based on a microprocessor.

IDENTIFY THE FOUR TYPES OF PERSONAL COMPUTER

1.Desktop computers are used in many places such as home, school and business.







2.Laptops are second common type used of personal computers.





 




3 Notebook use a variety of techniques, known as flat-panel technologies, to produce a lightweight and non-bulky display screen.









4.Palmtop computers are also types of personal computers and are so small that they can fit into the pocket of your coat. These computers have slow speed and less working capacity than previous two types of the computers. Palmtop Computers are mostly used by small businessmen and salesmen.
