TOPIC: COMPUTER AND MONITOR

REF. BOOK: Welcome to Computer Studies.  By BoyeJokotoye

CONTENT:

THE MONITOR

The monitor is an output device used to display information.  The monitor is also called Visual Display Unit (VDU).  It is similar to ordinary television screen.  The output on a monitor is called softcopy.  This output is available to the user only for as long as another output has not replaced it.  Thus, the output in the monitor is temporary.

A monitor is one of the most common output devices which is used to display information (either data or result) on the screen. 

TYPES OF MONITOR

There are two types of monitors.

1. Monochrome monitor.
2. Coloured Monitor.

MONOCHROME MONITOR

Monochrome monitors are very similar to black and white television sets.  They display their output in just one colour.  Monochrome monitors are of two types, Monochrome Text Monitor which can only display text and number character in single colour and Monochrome Graphics Monitor which can display texts as well as graphics such as charts, maps, diagrams and other pictures all in one colour.

COLOURED MONITOR

Coloured monitor can display text and pictures in more than one colour.  Different types of colour monitors have been developed.  These are:

1.   CGA (Colour Graphic Adapter) which can display only 16 colours.
2. EGA (Enhanced Graphic Adapter) which displays 64 colours.
3. VGA (Video Graphic Adapter).  This can display 262,144 colours.
4. SVGA (Super Video Graphic Adapter).  This can display more than 262,144  colours.

CATHODE RAY TUBE MONITORS

These are the most common type of monitors for office and the home. They make use of Cathode Ray Tube (CRT).

LCD MONITORS

Liquid Crystal Display (LCD) monitors were developed because of the bulky nature of CRTs.  Unlike the technology used in CRTs, the technology for portable monitors involves liquid crystals.  LCD monitors are thinner than CRTS.

EVALUATION

1. 1. What is a Monitor?

• Mention the two types of monitor.

CONCLUSION

We have learnt that the monitor is an output device used to display information.  We have also known the differences between the Cathode Ray Tube (CRT) and Liquid Crystal Display (LCD) monitors.

There are two types of monitors i.e. Monochrome and Colour monitors.  We have learnt that monochrome monitors can only display information in one colour while colour monitors can display information in more than one colour.

THE SYSTEM UNIT

A System unit also known as a base unit,  is electronic circuitry housed within the computer cabinet.  It is the part of the micro computer that contains the Central Processing Unit (CPU).

THE INTERNAL FEATURES OF THE SYSTEM UNIT

Is the main body of a personal computer, typically consisting of a plastic/metal enclosure containing thefollowing:

1. Motherboard,
2. power supply, 
3. cooling fans, 
4. internal disk drives, 
5. the memory modules and 
6. expansion cards that are plugged into the motherboard such as video and network cards. 

CENTRAL PROCESSING UNIT

The CPU is a processing device found inside the system unit. It is mounted on the motherboard which is also inside the system unit. The function of a CPU is to perform the processing of data received from the input devices. The major components of the CPU are as follows:

1. Arithmetic and Logic Unit (ALU)
2. Control Unit
3. Memory Unit

The system units of micro computers are of different shapes. These include the following:

(i) Notebook

(ii) Palmtop

(iii) Desktop

(iv) Tower

(v) Slim line etc.

NOTEBOOK

This is a micro computer that is small and light enough to be moved easily from one place to another.  It can fit into most briefcases.  They are the most popular computers today.

PALMTOP 

These are also known as Personal Digital Assistants (PDA) and are much smaller than laptops.  This device combines pen input, writing recognition, personal organizational tools and communication capabilities in a very small package.

DESKTOP 

These are small enough to fit on top or along the side of a desk and yet are too big to carry around.

TOWER 

Tower casing system unit is a little bit taller than the desktop, hence, it is placed under the table or on the floor.

SLIM LINE 

This is a system unit that stands independently beside the monitor and the keyboard.

Creating,saving and retrieve files

INTRODUCTION TO WORD PROCESSING PACKAGES

A word processing package enables you to type in and manipulate text.  It helps you to enter, store, format, copy and print text.  It is a software that turns the computer into a sophisticated typewriter.

With any type of word processing software, you can produce any kind of document, large or small, whether personal letter, business report, school report sheet, circular etc. and save the document for future reference.

The word processing software allows you to determine how you want the finished page to look i.e. page size, line, width, margin etc.  Once you are satisfied that everything look all right, you can print out any number of copies on paper.

FUNCTIONS OF WORD PROCESSING

1. Text correcting/Editing
2. Inserting paragraph
3. Deletion of sentence, words, paragraphs etc.
4. Correction of wring spelling
5. Inclusion of graphics

Examples of word processor: word perfect,word Star,MS-word,loco Script, Ami-Pro,Word Craft,notepad, WordPad.

Starting Microsoft word: Click the start button to bring the start menu; click program; click on Microsoft word

Create a new document: Click on file ,clicknew, start typing

Saving a document:click on file, click save, make a choice of location to save in, type the name you want to save it as, click command button ‘save’

Opening an existing document: click on file, clickopen, click on the document- saved- in location or other storage devices.

EVALUATION

• Define Word Processing Package?

1. State four uses of word processing.
2. List five examples of word processing packages.

FEATURES OF WORD PROCESSING PACKAGES

1. WORD WRAP –  Instead of pressing ‘Enter key’ at the end of every line while typing, word wrap automatically moves the insertion point  to the next line when you reach the end of the current line and allows you to continue typing without having to press the ‘Enter key’ to start a new line.
2. EDITING OF DOCUMENT– Once you have finished typing your document, you can then use WORD basic editing techniques.  These include inserting text, deleting text, moving paragraphs from one position to another, etc.
3. DELETING TEXT– Word processing features allows for deletion, that is, the removal of unwanted text.  Some can be deleted using ‘delete key’ while you can also press ‘back space key’ to delete text depending on where you place the cursor before deletion.
4. INSERTING TEXT– The process of adding text in-between existing text; it could be a character or a full statement.
5. PAGE FORMATING– This is the standard setting of page format.  Information in page formatting include the length of each line, number of lines per page, the size of the margin and line spacing.
6. SPELLING CHECKER– This is a program to detect and correct wrongly spelt words.  Spelling programs read word processing files and compare each word to the computer dictionary.  It then underlines any wrongly spelt word and gives suggested spelling options.
7. SAVE AUTO RECOVER– When you are working, you can sometimes forget to save regularly, which could mean you lose your work hence, you saved in the event of power outage.  Microsoft Word provides an automatic save feature that you can set to ensure that your documents are saved regularly.  However, this depends on the specific time interval in minutes set by you.
8. NON-PRINTING CHARACTER– Microsoft Word provides a feature called Non-Printing Characters that has certain landmarks you might find helpful as you create your document.  These keys include ‘ENTER key’, ‘TAB key’ and ‘SPACEBAR key’.  They are called non-printing character because though they appear on the screen, they will not appear in the printed document.

ADVANTAGES OF USING WORD PROCESSING PACKAGES

1. The use of computer allows for neat jobs.
2. It makes typing pleasurable.
3. There is room for corrections such that it does not leave any scar on the document.
4. With the use of computer, text could be formatted to suit the user’s taste.
5. It allows Mail Merging operation thereby relieving the secretary of the problem of having to type a particular document a number of times.
6. It allows the production of as many copies of the document as the owner will need and each appears as the original.
7. It has the capability of storing text for as long as it will be needed.
8. Document can be enhanced with graphics (pictures)

GENERAL EVALUATION

1. Define word processing.
2. List and explain five features of Word Processing 
3. State what word processing can be used for.
