Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.

Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

of low-power radio communications to link phones,
computers and other network devices over short
distances without wires.
5. Wi-Fi (Wireless Fidelity )

6. Father of Wi-Fi
The “Father of Wi-Fi,” Vic Hayes
is senior research fellow at Delft
University of Technology in
Delft, Netherlands.
7. How a Wi-Fi Networks Works
A Wi-Fi hotspot is created by installing an internet
connection.
A single access point can support up to 30 users.
Many acess points can be connected to each other via
ethernet cables to create a single large networks.
An access point acts as a base station.
9. Wireless Networks Types:
Wireless PAN – Performance Moderate ,
Cable replacement for peripherals
Wireless LAN – Performance High, Mobile extension
of wired networks
Wireless MAN - Performance High, Fixed wireless
between homes and businesses and the Internet
Wireless WAN - Performance Low, Mobile access to
the Internet from outdoor areas
11. Wi-Fi Technology
Wi-Fi networks use radio technologies to transmit and
receive data at high speed
IEEE 802.11 b
IEEE 802.11 a
IEEE 802.11 g
12. IEEE 802.11 b
Introduced in late 1999
4-6 Mbps (actual speed)
Most Popular
Least Expensive
100 – 150 feet range
Operates at 2.4GHz radio spectrum
Interference from mobile phones and bluetooth
devices which can reduce the transmission speed.
13. IEEE 802.11 a
Introduced in 2001
15 – 20 Mbps (Actual speed)
50 – 75 feet range

Introduced in 2003
54 Mbps speed

2.4 GHz radio frequencies
15. Latest technology in Wi-Fi
The latest Wi-Fi technology, called "802.11ac," offers
speeds of up to 1.3 Gigabits per second.
That's fast enough to transfer an entire high-definition
movie to a tablet in under 4 minutes, share photo
albums with friends in a matter of seconds or stream
three HD videos at the same time.
16. 802.11ac
We 're probably familiar with 802.11a/b/g/n, all of which are
protocols for the 802.11 wireless networking standard.
We can safely bet that any device with Wi-Fi connectivity,
from your laptop to your Smartphone, supports at least
wireless B or G, and if it came out within the past few years,
it should support wireless N. 802.11n (or the latest draft of
it, 802.11n-2009) is the fastest of the ones that are currently
widely available.
802.11ac is a new Wi-Fi protocol and is intended to be the
natural successor to 802.11n. We may have heard it called
"5G Wi-Fi" or "Gigabit Wi-Fi."
17. Elements of a Wi-Fi networks
Access point: The access point is a wireless LAN
transceiver or “ base station” that can connect one or
many wireless devices simultaneously to the internet.
Wi-Fi cards : They accept the wireless signal and relay
information. It can be external and internal.
Safeguards: Firewalls and anti-virus software protect
networks from uninvited users and keep information
secure.
18. Roaming
A wireless computer can "roam" from one access point to another, with
the software and hardware maintaining a steady network connection
by monitoring the signal strength from in-range access points and
locking on to the one with the best quality. Usually this is completely
transparent to the user; they are not aware that a different access point
is being used from area to area. Some access point configurations
require security authentication when swapping access points, usually
in the form of a password dialog box.
19. If we have more than one hardware access point then
how can we share a single Internet connection?
If an existing wired LAN already has an Internet
connection, then the hardware access points simply
connect to your LAN and allow wireless computers to
access the existing Internet connection in the same
way as wired LAN computers.
22. Conclusion
Wi-Fi is a universal wireless networking technology
that utilizes radio frequencies to transfer data. Wi-Fi
allows for high speed Internet connections without the
use of cables or wires.
Since nearly all new laptops come with internal
wireless cards
