Computers are everywhere

 Some people feel computers are too complicated for them to use without special skills and information.However, they interact with computers all the time while not necessarily realizing it.Look closely Computers are nearly everywhere, not simply in the conventional setup that includes a monitor, keyboard, and mouse. They are also found in everyday devices   such as mobile phones, lifts, televisions, and cars. From  watching movies to playing games, and even making   dinner, computers can be used to do almost anything.

Look closely 

Computers are nearly all over, not simply in the conventional setup that includes a monitor, keyboard, and mouse. They are also found in everyday devices   such as mobile phones, lifts, televisions, and cars. From  watching movies to playing games, and even making   dinner, computers can be used to do almost anything.

Household devices

Many household devices contain computers.  Selecting a program on a microwave, as an example, actually runs a small program on the computer embedded in the device.

Hardware and software

The physical and tangible parts of a computer are called hardware. These  include things we can see, such as the monitor and computer  case, as well as things we can’t see, such as the motherboard and  microprocessor inside the computer case. Things like programs,  the operating system, and firmware (a type of program that is  embedded into the microprocessor) are called software. They  allow users to access the capabilities of the hardware.

Input devices 

There are a lot of the way to input information and interact with software running on a computer. The most common ways to do this are by using   a keyboard, a mouse, or a touchscreen.

Looking for files

Searching for files on a computer is similar to finding them during a real-world filing cabinet. The file system on a computer   is usually assessed using a window containing small icons   of folders or documents. A folder can be opened to display  the files inside by touching with a finger on a touchscreen   or double-clicking with a mouse or trackpad.

Searching for files

The best way to look for a file is to find the magnifying   glass icon. Then, click on it and type the filename or   keywords in the search bar.

Opening files

A file name sometimes includes a punctuation mark followed by some letters.   This is the file extension, which identifies the type of file and tells  the computer what kind of program it should use to open it.

In the bin 

Deleting a file by mistake is quite common.   Deleted files usually go into the recycle or trash   bin, and can be restored by opening the bin   and taking the file out.

Moving data

There are various ways to transfer data between computers.  Emails can be used to attach pictures, documents, and   other files to a message. There are also systems, such as  Google Drive or Dropbox that allow people to upload   large files and folders to the cloud. These can be shared   with others through a link to the uploaded file, which can  then be downloaded, or even edited online.

Removable storage

 You can also move files  between computers   through storage devices   such as USB pen drives   and removable hard   drives. Data can be stored   on memory cards, which   can be plugged into  computers to be read.

REAL WORLD 

Saving and backing up

 Computers and applications can crash without warning. To avoid losing important work, it’s good observe to avoid wasting a file frequently while working on it. It’s also useful to back up files  using either a separate hard disk or an online backup service.  These services are a part of cloud computing, where people  use the storage facilities of a specialist provider to save data.
