CHAPTER 2 LITERATURE REVIEW: Online services have revolutionized the way we live our lives, providing us with convenience and efficiency. In this literature review, we will explore some of the online services that are particularly useful for PG and flat students, including laundry, carpooling, tiffin services, brokers, and book selling and buying. Laundry Services: According to a survey conducted by Statista, the laundry and dry cleaning market is projected to grow to $7.66 billion by 2022. Online laundry services like Washio, Laundryheap, and Rinse are gaining popularity among PG and flat students. These services offer pick-up and delivery services, allowing students to have their clothes cleaned without having to leave their homes. A study conducted by the University of Southern California found that students who used laundry services were able to devote more time to their studies and social lives. Carpooling: Carpooling is another popular online service among PG and flat students, as it helps to reduce transportation costs and carbon emissions. According to a study conducted by the National Renewable Energy Laboratory, carpooling can save students up to $600 a year in transportation costs. Online carpooling services like UberPool, Lyft Line, and BlaBlaCar allow students to share rides with others going in the same direction, making transportation more affordable and environmentally friendly. Tiffin Services: Tiffin services are becoming increasingly popular among PG and flat students who are too busy to cook their own meals. Online tiffin services like FreshMenu, Zomato, and Swiggy offer a variety of meals delivered right to the student's doorstep. A study conducted by the University of California, Los Angeles found that students who used tiffin services were more likely to eat healthier meals and save time and money. Brokers: Finding a suitable rental property can be a daunting task, especially for PG and flat students who are new to a city. Online brokers like NoBroker, NestAway, and Housing.com offer a range of rental properties that can be filtered based on budget, location, and amenities. According to a study conducted by the National Association of Realtors, 51% of homebuyers found their homes on the internet. Book Selling and Buying: Online bookstores like Amazon, Barnes & Noble, and Book Depository have made it easier for students to buy and sell textbooks. Students can compare prices from multiple sellers and purchase or sell books from the comfort of their homes. According to a survey conducted by Student Monitor, 69% of students said they purchased their textbooks online. In conclusion, online services have made it easier for PG and flat students to manage their daily lives. Services like laundry, carpooling, tiffin services, brokers, and book selling and buying have all become popular among students due to their convenience and affordability. As technology continues to evolve, we can expect to see more online services that cater to the needs of students.
