3) Mouse vs Touch Screen

Nowadays, computer is considered as on the necessary attributes in modern life. We use computers in order to make life easier, moreover it saves our private time. For example, it helps us to solve logical tasks; we can store, transmit and manipulate large amounts of information that is only possible with computer technology; through the computer we can easily communicate with people from any point of the world without having difficulties like it was some years ago, when people sent paper letters. Etc…

Today, a usual computer consists of two parts: soft ware and hardware.

     Software is a set of instructions, called a program, which tells a computer what to do

     Hardware is any electronic or mechanical part of the computer system that you can see or touch.  

           There are three basic hardware sections:

1)     1) The CPU

2)    2) The main memory

3)    3) Peripherals. They include:

-          Input devices (keyboard and mouse, touch screen)

-          Output devices (monitor and printer)

-          Storage devices (hard disks and CD/DVD-R drivers)

Now I’m going to write about MOUSE and TOUCH SCREEN.

Both of them are used for moving a cursor (or pointer) and select items on the display, but they are very different in using.

                

            MOUSE is hand held device that is connected to the computer by the USB-cable.  Mouse was invented earlier than Touch Screen, that’s why most of people prefer to use the mouse rather than the touch screen.

But, there are some disadvantages of using Mouse:

-          For using mouse you need smooth surface that is enough big (especially it’s hard when you are using mouse in the train or car )

-          Mice are being sold separately from the computer

-          By the time, it’s getting dirty. You can disassemble it for cleaning or washing, but for assembling you need glue

 TOUCH SCREEN is an electronic display that reacts on your touching (finger, hand). It’s easier in using, because you interact directly with what is displayed, rather than indirectly with a pointer controlled by a mouse. Moreover, it needn’t any extra devices for inputting that would to be held in the hand. Such displays can be attached to the computers.

               

             But, there are some disadvantages:

-          It requires a lot of energy

-          There is no tactile feedback

-          Touch screen is usually very thin, so even with the slight being damaged, it can stop working at all.

-          Hasn’t protection from being frozen  

In conclusion, I can say that mouse is getting less useful in inventing new types of modern computers. Anyway you will face with the Touch Screen, and you will have to use it!
