Difference Between Hackers & Crackers

 Difference Between Hackers & Crackers

The differences between hackers and crackers can be difficult to nail down. The exact definition of each, as well as questions of which are good and which are not, depend on who you ask and who you believe. Crackers are, according to hackers, unskilled and malicious whereas crackers believe that the differences are largely generational

Hackers

According to Chad Perrin of Tech Republic, a hacker is a person with a "strong interest in how things work." Hackers, says Perrin, are individuals who like to create, modify and tinker out of pure enjoyment. According to hacker Phillip S. Tellis, some of the early and best-known hackers included Steve Jobs of Apple Computers and Bill Gates of Microsoft. He states that all current computer security systems are a result of the work of hackers.

Crackers

Crackers agree that cracking does not take the same level of skill as hacking. According to the Cyberpunk Project, a Russian website, cracking involves "persistence and the dogged repetition of a handful of fairly well-known tricks that exploit common weaknesses in the security of target systems." According to the site, the primary difference between hackers and crackers is generational ideals. Hackers, it says, were influenced by the idealism of the "new-left" and the hippies while the crackers were influenced by the punk movement of the late 1970s.

Transaction Processing Systems

Transaction Processing Systems

Transaction Processing Systems
Transaction processing is supported by programs that are called transaction processing systems.
Transaction processing systems provide three functional areas:
System runtime functions
Transaction processing systems provide an execution environment that ensures the integrity, availability, and security of data. It also ensures fast response time and high transaction throughput.
System administration functions
Transaction processing systems provide administrative support that lets users configure, monitor, and manage their transaction systems.
Application development functions
Transaction processing systems provide functions for use in custom business applications, including functions to access data, to perform intercomputer communications, and to design and manage the user interface.
The services of a transaction processing system runtime environment include the following:
Scheduling and load balancing. Controlling the rate and order in which tasks are processed to give higher-priority tasks the best response times and to adapt to the availability of application servers and other system resources.
Managing system resources. Maintaining a pool of operating system resources to be used for transaction processing, loading application programs, and acquiring and releasing storage.
Monitoring. Monitoring the progress of tasks, suspending those waiting for input, adjusting task priorities, and resolving problems.
Managing data. Obtaining required data needed by tasks, coordinating resource managers (such as file servers and database managers), locking data for update, and logging changes.
Managing communications. Monitoring communications with users and between servers and other systems, starting communications sessions as needed, managing data handling and conversion, and routing data to the right destination.
Time management. Managing transaction processing in relation to the passage of time, starting tasks at predefined times, logging the date and time of events onto disk, and regularly controlling part of the business system to provide degrees of automation.
Services for systems administration and application development are described in subsequent sections.
How Does Transaction Processing Systems Works?
Transactions from ATMs in the United States go first to their own processor (the Acquirer). From that point, the connections branch out to different networks, issuing financial institutions, and sometimes other processors.
Each processor's data configuration is slightly different from the other. The route the transaction takes can vary considerably.In the end all transactions must make it to the card-issuing financial institution and back again. For this reason, ATM cardholders can use their cards almost anywhere in the United States.
We can thank the transaction processors for this remarkable state of affairs, because, one way or another, they have chosen virtually all of the networks to be their partners.
At the top of the "pyramid" are national networks Plus (Visa) and Cirrus (MasterCard), in addition to Discover and American Express. At the next level there are networks such as NYCE, Jeanie, Star (East and West), Mac, Quest, Pulse and others.
There are other, more specialized, networks that use the magnetic stripe card. One example is the Armed Forces Financial Network (AFFN). This extensive network serves all members of the U.S. military. President of Western Reserve Processors Mike Stevenson says there are approximately 200 different card issuers that will only be accepted on terminals on which the AFFN works.
In addition, there is the U.S. government Electronic Benefits Transfer (EBT) network that delivers food stamps and cash benefits, like Temporary Assistance to Needy Families (TANF). As states consider additional programs, such as Social Security and Unemployment Compensation, which could be delivered with the same card, the EBT is rapidly changing to the Electronic Services Delivery (ESD) system.

What are Web mashups and what technology makes them possible?

What are Web mashups and what technology makes them possible?

A web mashup is a Web page or application that uses and combines data, presentation or functionality from two or more sources to create new services. The term implies easy, fast integration, frequently using open APIs and data sources to produce enriched results that were not necessarily the original reason for producing the raw source data.
Mashups composition tools are usually simple enough to be used by end-users. They generally do not require programming skills, they rather support visual wiring of GUI widgets, services and components together. Therefore, these tools contribute to a new vision of the Web, where users are able to contribute.
Web mashups combine the capabilities of two or more online applications to create a hybrid that provides more customer value than the original sources alone.
With Application Programming Interfaces (APIs), programmers are able to get the tools needed to pull data from different websites and combine it with other information to make an entirely new Web service. As a result, the web is becoming a collection of capabilities instead of being collection of pages. It is allows programmers to create new services quickly and inexpensively

Global Positioning System(gps)

Global Positioning System(gps)

Global Positioning System(gps)  is theis a space-based satellite navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth . As my privious topic was USE OF e-COMMERCE you may visit this topic just by clicking such bold and Hyperlinked word. Today my topic is on GPS system and What is the GPS and How GPS wotks? These all quries will be resolved below.

How accurate is Global Positioning System(gps)?

Today's GPS receivers are extremely accurate, thanks to their parallel multi-channel design. Garmin's 12 parallel channel receivers are quick to lock onto satellites when first turned on and they maintain strong locks, even in dense foliage or urban settings with tall buildings. Certain atmospheric factors and other sources of error can affect the accuracy of GPS receivers. Garmin® GPS receivers are accurate to within 15 meters on average.

Top Ten Benefits of Encryption

Top Ten Benefits of Encryption

In a world that’s moving towards visualization and cloud, the need for encryption is even more important, and the need for organizations to retain control over data, particularly in cloud environments, is paramount. Below are top 10 benefits for those considering encryption.

1. Encryption Helps Move to the Cloud

Everyone is concerned about moving sensitive data to the cloud, and most organizations perceive that the cloud is not as safe as their own data center. If your data is in the cloud, it’s not only possible that strangers might see it, but your data could be sitting on the same storage as your competitors. Imagine how much that treasure chest could be worth?

Encryption can make it possible to leverage the benefits of infrastructure as a service, while still ensuring the privacy of your data. You should ensure data is encrypted in flight, while in use, and at rest in storage. By retaining control of your encryption keys, you’re still in control, even when data has left your building. If the service provider makes copies of your VMs, only encrypted data is copied. And at all times, you determine when to deliver, or revoke, the keys.

2.  When You Own the Keys, You Can Easily Decommission/Deprovision

Would you put your jewels in a safe and give a stranger the key? Would you have your data encrypted in the cloud and have the cloud service provider own the keys? Probably not the most secure option.
