1. Introduction to GUI Based Operating System
1.0 Introduction
An operating system (OS) is an interface between hardware and user. We will now discuss various user-friendly
features of windows operating system. Microsoft has produced several Operating Systems. Windows 95/98/ME,
Windows NT, Windows 2000 Professional / Advance server, Windows XP, Windows Vista are some of them.
1.1 Objectives
In this chapter you will be learn about
Linux is an operating system that was initially created as a hobby by a young student, Linus Torvalds, in 1991. In
1994 the first version of Linux Kernel was released on Internet. At the end of 2004, 50 % Linux has been adopted
worldwide primarily as a server platform. From 2007 various well-known computer manufactures have started
delivering some of the models they are manufacturing with Linux preloaded.
Linux is a example of Open Source Code Operating System. It is having nearby all the features present in Unix
Operating System. Linux also supports TCP/IP protocol, and we can access Local Area Network and Internet.
Linux is generally provided with two types of Graphical User Interface one is KDE and other is Gnome. Other
interfaces are also available. Command interpreter is also available. The programs developed for Windows do not
run on Linux and similarly programs developed for Linux do not run on Windows.
Today Linux is used in nearby every field as Government and Private Offices, Education, Various Training’s,
Homes, Businesses and other. Now most of the versions of Linux are available at very reasonable cost or sometime
totally free of cost. Also, Linux provides more security compared to Windows.
Windows
Windows family of operating systems are based on Graphic User Interface (GUI) and can be used on a desktop
Computer.
Windows-9x
The term Windows 9x refers to three operating systems viz. Windows-95, Windows-98 and Windows-me.
Windows-95 was released in the year 1995, It was plain and simple operating system, mainly developed for stand-
alone computers.
Windows-98 was released in the year 1998. In was enhanced version of Windows-95. Internet related aspects were
included in it and Internet Explorer, the web browser, was made part of it.
Another version of Windows, called Windows-me was released in the year 2000. Me stands for Millennium. It was
released as enhanced version of Windows-98 but had many internal problems, due to which it used to frequently
crash. Windows-me had improved multimedia capabilities, video editing features and enhanced Internet facilities.
Windows XP
Yet another improved version of Windows, called Windows-XP was released in the year 2001. It is 32-bit
operating system that is quite popular on personal computers and laptops. It is quite stable product and is being
continuously used till date. Many variations of Windows XP are there. They are named as Windows XP
Professional, Windows XP Home, Windows XP Media center Editing and Windows-XP Embedded. The Microsoft
has created 64-bit version of Windows-XP to run on them.
Windows 7
Windows 7 is a best OS of Microsoft. it is a series of operating systems produced by Microsoft for use on personal
computers, including home and business desktops, laptops, net books, tablet PCs, and media center PCs.
Taskbar is generally displayed at the bottom of the window, but you can change its position, also its size can be
changed. If you lock the taskbar then it is not possible to change its size and position. When the taskbar is hidden,
it appears only when the mouse cursor is pointing on the taskbar’s position, when the mouse is moved from that
position the taskbar is automatically hided. Various Quick Launch, Date and Time are also displayed on the
taskbar.
1.3.2 Icons
When you start (booting) the Computer. After completion of the booting process the first screen displayed is called
as Desktop. Various Items including Icons are present on this Desktop. With the help of these icons we can
quickly access various programs, files and folders. Various shortcuts for programs, files, folders, disks etc are
provided with the help of icons. Icons are special types of buttons which include image and label given to that
button.
Start menu or Start button provides list of commands to perform various jobs and applications. In various versions
of Windows Start menu is displayed with the start label. In Windows Vista Start menu is displayed with the start
button.
With the help of Start Menu you can turn off of log off the computer also you can switch between users. Various
hardware and software setting can be changed with the help of control panel provided in the Start Menu. If you
need any help while working in Windows, it is available on the start menu. You can use various accessories and
other system tools provided with Windows with the help of Start Menu.
Windows Operating System offers a powerful option called Control Panel through which windows settings can be
changed. Control panel holds a group of tools that help to change the software and hardware settings.

decision will remain as you continue to type (provided you don’t change these settings).
2.5.2 Alignment of Text
Configure alignment
The alignment settings control the horizontal position of the paragraph text between the page margins. There are
four alignment options:
• Align Left: This is the default paragraph alignment. It sets the left end of each line of the paragraph at the
left page margin or left indent. It results in a straight left edge and a ragged right edge.
• Align Right: This sets the right end of each line of the paragraph at the right page margin or right indent. It
results in a straight right edge and a ragged left edge.
• Center: This centers each line of the paragraph between the left and right page margins or indents. It results
in ragged left and right edges.
• Justify: This alignment adjusts the spacing between words so that the left end of each line of the paragraph is
at the left page margin or indent and the right end of each line of the paragraph (other than the last line) is at
the right margin or indent. It results in straight left and right edges.
2.5.3 Paragraph Indenting

for different parts of the document, such as paragraphs and headers.
make a numbered list are the same, except the icon for numbering is
TIP: For style or space, explore decreasing indent space for lists. Bullets or numbers automatically indent to set
lists apart from regular text. But if you like the style of left margin alignment, the bullets or numbers set the list
apart from the text sufficiently.
1. On the Insert tab, in the Tables group, click the Table button. The Insert Table menu appears.
2. Point to the cell in the fifth column, second row. The menu title should read 5x2 Table, as shown in Figure 6-2.
Click the mouse button to create the table. Once the table is inserted in the document, you are ready to begin
entering text. Later in this lesson, you enter data into the table.
3. Click below the table and press Enter twice to insert blank lines. When you insert more than one table in a
document, you should separate them with a blank line to avoid joining the tables.
2.6.1 Draw a Table

2.6.3 Sorting a Table’s Contents
To sort data means to arrange it alphabetically, numerically, or chronologically. Sorting displays data in order so
that users can locate it more quickly. You can sort text, numbers, or dates in ascending or descending order.
Ascending order sorts text from beginning to end, such as from A to Z, 1 to 10, or January to December.
Descending order sorts text from the end to the beginning, such as from Z to A, 10 to 1, or December to January.
In this exercise, you practice sorting data in a Word table using the Sort dialog box, which you access through the
Sort command on the Table Tools - Layout tab in the Data group.
1. Place the insertion point anywhere in the first column. On the Table Tools - Layout tab, in the Table group,
click the Select button and Select Column.
2. On the Table Tools - Layout tab, in the Data group, click the Sort button. The Sort dialog box appears, as
shown in Figure 6-11. Because you selected the Company Name column, the Company Name data is listed in
the Sort by text box, with Ascending order selected by default. The column contains text; therefore, the type
was listed as Text. The other options under type are Number and Date.
3. Click OK. Note that the table now appears sorted in ascending order by company name.
To Insert a Column:
1) Position the cursor in the table where you would like to insert a column

What is Network?
A network consists of two or more computers that are linked in order to share resources (such as printers and CDs),
exchange files, or allow electronic communications. The computers on a network may be linked through cables,
telephone lines, radio waves, satellites, or infrared light beams.
What is Internet?
The Internet, sometimes called simply “the Net,” is a worldwide system of computer networks – a network of
networks in which users at any one computer can, if they have permission, get information from any other
computer. It was conceived by the Advanced Research Projects Agency (ARPA) of the U.S. government in 1969
and was first known as the ARPAnet.
Today, the Internet is a public, cooperative and self-sustaining facility accessible to hundreds of millions of people
worldwide.
3.1 Objectives
After Completing this lesson, you will be able to:
Transmission Technology:
It refers to the technology by which data from source is transmitted to the destination. These days varies from 10
Mbps to 1000 Mbps (1 Giga Bits per second) or even more.
Wireless Local Area Networks are much like LAN networks, except they do not require network cables to connect
each other.
Metropolitan Area Network is a network system that covers area of a single city. MAN connects more than one
LANs in a city or town and covers a smaller geographical area than a WAN.
3.2.2 Wide Area Networks (WAN)
WAN covers a wide geographical area which includes multiple computers or LANs. It connects computers through
public networks, like telephone system, satellite link or leased line.
3.3 Internet
Internet is the world’s largest computer network and is described as a network of networks. One of the greatest
things about the Internet is that nobody really owns it. It is a global collection of networks, both big and small.
These networks connect in many different ways to form the single entity that we know as the Internet. The term
“The Internet” was first used in 1982 and Network uses TCP/IP protocols.
The Internet is an example of a network that connects many WANs, MANs, and LANs into the world’s largest
global network.
The Internet is a global collection of computer networks that are linked together by devices called routers and use
a common set of protocols for data transmission known as TCP/IP (transmission control protocol / Internet
protocol). The primary purpose of the Internet is to facilitate the sharing of information.
5.3.2 Basic of Internet Architecture
The internet architecture can be broadly classified into three layers. The very first layer consists of Internet
Backbones and very high-speed network lines. The National Science Foundation (NSF) created the first high-speed
backbone in 1987 called NSFNET, it was a T1 line that connected 170 smaller networks together and operated at
1.544 Mbps (million bits per second). IBM, MCI and Merit worked with NSF to create the backbone and
developed a T3 (45Mbps) backbone the following year. Backbones are typically fiber optic trunk lines. The trunk
line has multiple fiber optic cables combined to increase the capacity. Fiber optic cables are designated OC-48 can
transmit 2,488 Mbps (2.488 Gbps). The nodes are known as Network Access Point (NAPs). The second layer is
usually known as Internet Service Provider (ISP). The ISPs are connected to the Backbones at NAP’s with high
speed lines.
The end users which are part of third layer are connected to ISPs by dial up or leased lines and modems. The speed
of communication is usually 1400 bps to 2048 kbps.
• Telnet
The Telnet ‘Terminal Emulation’ software support, which to communicate with a computer connected via a
TCP / IP stack.
• Electronic Mail
E-mail is use to deliver, text, image, audio or video recording from one computer to another.
Before the World Wide Web and FTP was the only way to transfer large files between computers of Internet users.
• Chat
This service allows the Internet to one or more of Internet users who are hooked to the same channel at the same
time see the text that you type on your computer, and the texts of other active users typing on his computer.
• Social networks
A dedicated website or other application which enables users to communicate with each other by posting
information, comments, messages, images, etc. that’s called Social Networks.
Most of the technologies that are unique to the Internet require communication to be done in text—letters with
some symbols and punctuation.
1. Internet connection
2. Modem
3. Telephone line
4. Program which controls the communication of data over the hardware component.
Internet services typically provided by ISPs include Internet access, Internet transit, domain name registration, web
