WORD PROCESSING
Word processing refers to creating, editing, formatting, storing and printing a typed text called document. To do this, a word processor or word processing software is needed. Examples of word processors are Microsoft Word, Note pad, etc.

In some organizations, word processors have virtually replaced typewriters as a means of producing documents.

Advantages of word processing

Word processing has a lot of advantages over using a type-writer to type documents. These include:

Easier formatting of documents.

Ease of correcting and editing documents.

Pictures, diagrams and other graphics can easily be inserted into documents.

One can easily copy the format or design of an existing document and use it in a new document.

Text and graphics can be moved around easily within a document.

Word processing allows us to have a more colourful and attractive document design.

It is easy to type special characters such as superscript, subscript, etc. using a word processor.

Examples of word processors

Microsoft word.

Word perfect.

Word star.

Ami pro.

Note pad.

Uses of a word processor

Computerized typewriting.

Creation of document.

Spelling and grammar checking.

Finding and replacing text strings.

Creating indexes and table of contents automatically.

Basic Computer Operations for SS1
Definition of Booting
In computing, booting (also known as “booting up”) is a bootstrapping (self-starting) process that starts the operating system when the user turns on a computer system. Booting can also be defined as the initial set of operations that the computer performs when power is switched on.

Description of the Booting process

When the computer’s power is first turned on, the CPU (Central Processing Unit) initializes itself to look for the system’s ROM BIOS (Read Only Memory Basic Input Output System) which is the first program that runs every time the computer is turned on. The BIOS performs the Power-On Self-Test (POST), which begins by checking the BIOS chip and then test CMOS (Complementary Metal Oxide Semiconductor) RAM.

Computing Devices and their usage

Computing devices are the electronic devices which take
inputs, process the inputs and then calculate results from
the inputs. Or in simple words, these are basically the
mathematical devices which can do the math much in
faster way. One of the most common computing device is
computer which we all know about it.

This is the vast field and it covers huge amount of devices
today which we are using in one or another form and
these devices ranging from the simple Calculator,
Printers, Digital Cameras, Mobile phones, Smart phones ,
PC Desktops, Laptops and many more. These all do the
math calculations on the streams of binary digits (bits i.e.
0 and 1 ) and produce the results in different forms that
we need.
