What is Text ?

Text  is  obviously  the  simplest  of  data  types  and  requires  the  least  amount  of  storage.

Text in the form of words, sentences, and paragraphs is used to communicate thoughts, ideas, and facts in daily life.

Text  may  not  be  as  visually  exciting  as  some  of  the  other  media  types,  but  it  often  conveys  essential  and  precise  information.

Text elements

Alphabet characters

    A – Z and a – z 

Numbers

    0 – 9 

Special characters

    Punctuation (. ,  ; “ ‘ ! : -  /)

    Signs ($ + - = @ # % ^ & *)

Obtaining Text

Text can be captured in following ways:

• Keyboard
• Mouse
• Scanner (OCR) – Optical Character Recognition ((designed to translate images of handwritten or typewritten text (usually captured by a scanner) into machine-editable text ))

Types of Text

Unformatted text (Plaintext)

comprise strings of fixed-sized characters from a limited character set. 

Formatted text (Richtext)

comprise strings of characters of different styles, size and shape together with tables, graphics and image inserted at appropriate point.

Example: Rich Text Format (RTF), HTML, .doc

Hypertext

It enables the integrated set of documents (each comprising formatted text) to be created which have defined linkages between them.

What is an Operating System?

Operating System is :
A program that acts as an intermediary between a user of a computer and the computer hardware.

Operating system goals:

• Execute user programs and make solving user problems easier.
• Make the computer system convenient to use.
• Use the computer hardware in an efficient manner.

Some definition of operating system :

* OS is a resource allocator
    Manages all resources
    Decides between conflicting requests for efficient and fair resource use

* OS is a control program
    Controls execution of programs to prevent errors and improper use of the computer

* No universally accepted definition

* “Everything a vendor ships when you order an operating system”is good approximation
      But varies wildly

* “The one program running at all times on the computer”is the kernel. Everything else is either a system program (ships with the operating system) or an application program
