2. This Presentation Includes:
• Introduction to windows with its GUI/Features,
• Types of operating system
• Exploring Windows
• Network Configuration
• Network Interface Card
3. GUI(Graphics User Interface)
• GUI is a program interface that
takes advantage of the computer
graphics capabilities to make the
program easier to use.
• Well-designed graphical user
interfaces can free the user from
learning complex command
languages.
4. Basic Components of a GUI
1. Pointer: A symbol that appears on
the display screen and moves to
select objects and commands.
• Usually the pointer appears as a
small angled arrow.
• Text processing applications use an I-
beam pointer shaped like a capital I.
2. Pointing device: A device, such as a
mouse or a trackball, that enables you
to select objects on the display screen.
5. Basic Components of a GUI
3. Icons: Small pictures that represent
commands, files, or windows.
• By moving the pointer to the icon and
pressing a mouse button, you can execute a
command or convert the icon into a window.
4. Desktop: The area on the display screen
where icons are grouped is often referred to as
the desktop because the icons are intended to
represent real objects on a real desktop.
6. Basic Components of a GUI
5. Windows: You can divide the screen into
different areas.
• In each window, you can run a different
program or display a different file.
• You can move windows around the display
screen, and change their shape and size at
will.
6. Menus: Most graphical user interfaces let
you execute commands by selecting a choice
from a menu.
7. Parts of a Windows
• The Title Bar: It is on the top of
every window.
• The center of title bar displays
either name of currently
working program or relevant
information about what is
happening in the program at
any given moment.
8. Parts of a Windows
• The Menu Bar: Visible on the
upper left-hand corner of the
window.
• Appears as text and usually starts
with “File” at the far left.
• Accessing the menu allows to view
various commands available to that
program, including closing the
program or the window.
9. • The Scroll Bar: On the right
side and bottom of the
window is scroll bar.
• It appears only if there is
information to be displayed
beyond the bottom range of
the current window size.
• Clicking and dragging on the
slider in scroll bar, contents of
window moves up-down and
left-right to view data
available.

10. Parts of a Windows
• The Work Space: All of the areas
inside the window where data for the
current program is displayed.
• Usually, the workspace has a white
background, but it is possible to
customize this in all versions of
Windows, and it may vary by program.

11. Basic Functions of Windows
• The interface between user and hardware
• Coordinate hardware components
• Provide an environment for software to function
• Provide structure for data management
• Monitor system health and functionality
13. Network Configuration Hardware
• Network configuration is the process of
setting a network’s controls, flow, and
operation to support the network
communication of an organization
and/or network owner.
• This broad term incorporates multiple
configuration and setup processes on
network hardware, software, and other
supporting devices and components.
14. Network Interface Card
• A network interface card (NIC) is a
hardware component without which a
computer cannot be connected over a
network.
• It is a circuit board installed in a
computer that provides a dedicated
network connection to the computer.
• It is also called a network interface
controller, network adapter or LAN
adapter.
15. Purpose of NIC
• NIC allows both wired and wireless
communications.
• NIC allows communications between
computers connected via local area network
(LAN) as well as communications over the
large-scale network through Internet Protocol
(IP).
• NIC is both, a physical layer and a data link
layer device, i.e. it provides the necessary
hardware circuitry so that the physical layer
processes and some data link layer processes
can run on it.
16. Types of NIC Cards
Internal Network Cards
• In internal network cards, motherboard
has a slot for the network card where it
can be inserted.
• It requires network cables to provide
network access.
These are of two types:
• First type uses the Peripheral
Component Interconnect (PCI)
connection.
• Second type uses Industry Standard
Architecture (ISA)
17. External Network Cards
• In desktops and laptops that do not have
an internal NIC, external NICs are used.
These are of two types:
• Wireless
• USB based.
• They are useful while traveling or
accessing a wireless signal
