Ebay is an online auction and shopping website founded in 1995 that facilitates consumer-to-consumer and business-to-consumer sales. It was founded by Pierre Omidyar and became very successful during the dot-com bubble. Today it operates in 30 countries and generates billions in revenue through listing fees and commissions on completed sales. Ebay partners with PayPal to allow easy and secure online payments between users.
If you want to become an eBay power user, you need to get
all the background information you can before you start
buying and selling. After all, for both new and experienced
users, eBay functions much like a business partner. You pay
fees for selling items on eBay. All of your business activities
take place under eBay’s supervision. Knowing something
about the ideas behind eBay will give you an idea about how
to conduct your own business activities there.
It’s amazing to think that my nine-year-old daughter will grow
up thinking that eBay always existed when in fact eBay is relatively
new. In the beginning, when it wasn’t regulated, eBay
evolved in a haphazard, personal fashion. If you are wondering
where all the regulations and rules came from, you only
have to look at how things worked before the site was popular
and before it became a highly organized business operation.

Techniques to optimize the pagerank algorithm usually fall in two categories. One is to try reducing the work per iteration, and the other is to try reducing the number of iterations. These goals are often at odds with one another. Skipping computation on vertices which have already converged has the potential to save iteration time. Skipping in-identical vertices, with the same in-links, helps reduce duplicate computations and thus could help reduce iteration time. Road networks often have chains which can be short-circuited before pagerank computation to improve performance. Final ranks of chain nodes can be easily calculated. This could reduce both the iteration time, and the number of iterations. If a graph has no dangling nodes, pagerank of each strongly connected component can be computed in topological order. This could help reduce the iteration time, no. of iterations, and also enable multi-iteration concurrency in pagerank computation. The combination of all of the above methods is the STICD algorithm. [sticd] For dynamic graphs, unchanged components whose ranks are unaffected can be skipped altogether.
As Europe's leading economic powerhouse and the fourth-largest hashtag#economy globally, Germany stands at the forefront of innovation and industrial might. Renowned for its precision engineering and high-tech sectors, Germany's economic structure is heavily supported by a robust service industry, accounting for approximately 68% of its GDP. This economic clout and strategic geopolitical stance position Germany as a focal point in the global cyber threat landscape.
In the face of escalating global tensions, particularly those emanating from geopolitical disputes with nations like hashtag#Russia and hashtag#China, hashtag#Germany has witnessed a significant uptick in targeted cyber operations. Our analysis indicates a marked increase in hashtag#cyberattack sophistication aimed at critical infrastructure and key industrial sectors. These attacks range from ransomware campaigns to hashtag#AdvancedPersistentThreats (hashtag#APTs), threatening national security and business integrity.
🔑 Key findings include:
🔍 Increased frequency and complexity of cyber threats.
🔍 Escalation of state-sponsored and criminally motivated cyber operations.
🔍 Active dark web exchanges of malicious tools and tactics.
Our comprehensive report delves into these challenges, using a blend of open-source and proprietary data collection techniques. By monitoring activity on critical networks and analyzing attack patterns, our team provides a detailed overview of the threats facing German entities.
This report aims to equip stakeholders across public and private sectors with the knowledge to enhance their defensive strategies, reduce exposure to cyber risks, and reinforce Germany's resilience against cyber threats.

3. eBay Inc. E-bay is a multinational e-commerce corporation headquartered in San Jose,
California that facilitates consumer-to-consumer and business-to-consumer sales
through its website. eBay was founded by “Pierre Omidyar” in 1995, and became a
notable success story of the dot-com bubble. Today, eBay is a multi-billion-dollar
business with operations in about 30 countries. The company manages eBay.com, an
online auction and shopping website in which people and businesses buy and sell a
wide variety of goods and services worldwide. The website is free to use for buyers, but
sellers are charged fees for listing items after a limited number of free listings, and again
when those items are sold.
Introduction
4. This company was founded in 1995 in San Jose, CA by Iranian-American computer
programmer Pierre Omidyar. It was originally called AuctionWeb. In 1997, the
company was renamed to Ebay and received $6.7 million in funding from
Benchmark Capital. In March 1998, Ebay had 30 employees, half a million users
and revenues of $4.7 million in the US. By early 2008, the company was worldwide,
had hundreds of millions of registered users, 15,000+ employees, and revenues of
almost $7.7 billion.
History
5. Ebay is a consumer-to-comsumer company, meaning consumers facilitate
transactions and sell things to other consumers. It is a decentralized network where
users/nodes are able to join or leave at any time they would like. Users also
communicate/interact with each other on this website
Structure of the Company
7. Complementary Products/Services - Competitors
Amazon allows users to purchase items, like Ebay. However, Amazon doesn’t offer
these products through auctions. Ebay offers it’s “buy it now” option, which is similar to
Amazon. In a way, I think Ebay has an upper hand because you can purchase and bid
on things, whereas, Amazon only allows people to purchase. Also, another similar
service is how each site makes suggestions to users for things they might like based on
searches and/or recent purchases. Amazon and Ebay both allow customers to rate
sellers. Ebay also allows sellers to rate buyers, which allows sellers to know if this buyer
is legitimate.
Overstock.com is similar to both of these sites, in that it also allows consumers to
purchase items. Although this site doesn’t allow you to bid on items either.
8. Partners
Pay Pal
Ebay has acquired
companies like Craigslist, Skype, and a
German website called brands4friends
9. Complementary Products/Services - Partners
Craigslist is very similar to Ebay, in that it allows consumers to sell things to each
other. It doesn’t do it through auctions, but rather through classified ads, meaning
the ads are organized into categories where you can look for what you want.
10. User Base
As of June 30, 2012, eBay had 104.8 million active users according to
their latest financial report.
12. Collaborate, Coordinate, & Compete
Ebay collaborates with Paypal. This allows them to give users an easier way to pay
for the products that they purchase on the website and helps protect their customer’s
information when making purchases. This makes people feel more comfortable
because there is so much fraud and identity theft present in today’s society.
Ebay coordinates with sellers to allow them to use their
website to sell/buy things. Sellers can create their “store” to sell
their products to people. Some people make stores that sell like items, for example,
DVDs. Other people sell random items that they are trying to get rid of
13. Assets/Tools
•Sellers rate buyers and vice versa. This
helps people feel like they can trust the
people they buy from.
•When you go back to their homepage it
gives you
items that are similar to what you have
previously searched for.
•An asset is pay pal because it ensures safe
purchasing and makes people feel safe when
using their cards to buy things. This is a huge
asset because without this it could hurt their
business. With so much identity theft today, who
would want a stranger having their credit card
information.
•They offer global shipping, which helps anyone
access the items.
14. Funding
The only information that I could find on funding for Ebay was that the company
received $6.7 Million in funding from Benchmark Capital in 1997.
15. Revenue
Ebay has several ways of generating revenue. They use broker fees. Ebay
charges a listing fee and then also charges for selling the item once it is sold. As
of November 2012, they take $0.10 to $2 (based on the opening price) for the
listing and 9% of the sale. An interesting way they are able to earn more revenue
is by getting more people to use pay pal because according to Wikipedia, when
someone who initially set up their pay pal account through ebay uses their pay pal
for a non-Ebay transaction, Ebay earns offsite revenue.
16. Intellectual Property
Ebay has a statement on their website stating that they work very hard to protect
intellectual property. They don’t allow people to use intellectual property, such as
copyrighted material, in an unlawful way. The Ebay name and logo are
registered trademarks in the US and internationally. They don’t allow the sale,
register, or use of the domain names.
17. Distribution
Ebay distributes consumer-to-consumer, which means consumers sell
and distribute to other consumers. Also, I can see that they distribute
through long tails because they offer a large number unique items, but
sells relatively small quantities of them.
18. Personalized and Customized Results
Ebay offers customized and personal results on their site. When you search for
items on the site they save what you have searched for and when you return to
the site the homepage offers related items that you may like.
