Explanation:
In Java, Aggregation is a relationshipthat exists between two classes that is best described as a "has-a"
Answer:
Explanation:
World Wide Web (www) has advanced as a major technology since its introduction during the 1980s. In beginning web sites were primarily used only by few number of users to share information related to their academic work. As the user interface evolved over the next coming years with each new version bringing in new frameworks and techniques, it powered web as a hub of technology. Web 1.0, 2.0 and 3.0 brought more dynamic features to the users. Web 1.0 used to describe the web content in static resulting in rigid user experience. Web 2.0 which powered social networking sites became popular developing the web which ultimately served as a platform for people to create and share their own content on the web in the form of blogs, wikis, feeds, tagging systems, user-created publication systems etc. The evolution of web technology began to spread its roots into the major business areas which brought in the requirement for high speed and expanded availability for substantial number of users.
On the other hand, Web 2.0 has also brought some security’s concerns. Mainly the component of client interaction with web, it opened doors to unauthorized actions in the application. In order to provide a rich user experience majority Web 2.0 sites have adopted lightweight user interface code such as asynchronous JavaScript and XML (AJAX). In the Conventional client-server models, many of calls (requests) are handled and processed on the server side. AJAX allows a higher percentage of requests to be processed on the client side. This may give malicious users many options to modify any application code running on a client machine by exploring and testing the application for vulnerabilities.
To overcome this objective, developers should consider installing an appliance at the Internet gateway, which performs real-time code inspection of traffic flowing through the corporate network. High performance and high availability appliances capable of monitoring and acting swiftly to block any suspicious web traffic are paramount. Also, it is very important that developers develop the application with security in mind. Following the coding convention, having the code reviewed, testing the application thoroughly are all part of securing the application in the web.
Answer:
a) only one digit changes as the number increases.
Explanation:
Let us first understand what does it mean when we say only one digit changes as the number increases using the Reflected Binary code (also called Gray code)
consider the 4 bit representation of Binary coded decimal and RB codes
Decimal | Binary code | Reflected binary (RB) code
0 0000 0000
1 0001 0001
2 0010 0011
3 0011 0010
4 0100 0110
5 0101 0111
As you can see in the case of binary codes, there are more than one digit changes between two consecutive numbers.
But notice that in the case of Gray codes, there is always one digit change between two consecutive numbers.
The problem with the binary codes is that the more digits change there states the greater is the chance of ending up with random transitional values rather than real values which can be incorrect. The RB code solves this problem by only changing one digit at a time.
The RB code is widely used in linear and rotary encoders, error correction and digital logic design.
