Describe NoSQL and its purpose. Explain how it is used differently than MySQL. M12 jan30 az

Describe NoSQL and its purpose. NoSQL is a highly scalable and reliable non-relational databases designed to maintain high performance and to be highly cost efficient for workloads of any scale, from the smallest to the largest internet-scale applications. It is also used to build a new kind of database for "unstructured" information that comes spilling off the Internet with each passing second. It is capable of handling large amounts of data du to the fact that they use flash storage rather than traditional spinning disks. These solid-state drives can provide single-digit millisecond response times. Explain how it is used differently than MySQL. MySQL database is a relational database that stores data in neat rows and columns, and it's designed to run on a single machine, while NoSQL database can store data in a more flexible way and is designed to scale across a very large number of machines. "SQL databases are like automatic transmission and NoSQL databases are like manual transmission. Once you switch to NoSQL, you become responsible for a lot of work that the system takes care of automatically in a relational database system. Similar to what happens when you pick manual over automatic transmission. Secondly, NoSQL allows you to eke more performance out of the system by eliminating a lot of integrity checks done by relational databases from the database tier. Again, this is similar to how you can get more performance out of your car by driving a manual transmission versus an automatic transmission vehicle." http://stackoverflow.com/questions/2559411/sql-mysql-vs-nosql-couchdb

Describe the major areas of search engine optimization. m12 nov 10 alec

1. Building Quality Back Links to Your Website - the way to a better ranking is to have quality websites link to yours. Such as websites in you niche or social media websites. If your site has these types of links search engines are more likely to give you website a higher ranking. 2. Anchor Text in Back Links - using anchor text also gets you a higher ranking, for example: if you use the URL www.sourcelinemedia.com - then the search engine only sees the site domain as part of its rankings. If you use anchor text such as Website Marketing and Design then search engines will rank you higher for anyone that searches for website marketing or website design. 3. On Page Optimization - Using key words helps to optimize your websites hits during a search. For example a site that has many key words relating to the information in its articles is more likely to get a hit on a search because the words relate to what they are searching. For example if you search Social Networking sites like Facebook, Twitter, and Tumblr would come up as the top few hits.

Explain how Google's algorithm works. Why is it hard to rank high? all nov 9 johny

The Google algorithm is also called as page ranking. Page Rank depends on the outstandingly democratic nature of the web via to enormous link structure as the sign of the values for each individual page. Google would understand a page A to page B as vote; it would look noticeably more at links age receiver and the sheer volume of votes. It would analyze what you are searching for and it would pick pages the most important page from the rest of the file that is relevant to your topic. Sometimes important pages wont answer you question. That's why Google page rank is combined with complicated text matching techniques to find the page that is important and similar to your question. Google does more then searching pages that has a match to your question it would examine the feature of the page content (satisfied) and that it would decide that is this page is a good match of your question. Because many websites don't have the possibilities to get highly ranked, because they also need to compete with other websites that comes from the company and they got millions of back links. For example you want to make a website about selling second hand stuff. When your going to try to search about second hand stuff it would directly show you E-Bay because it more popular and it has more views. The websites that you may been searching for must be on the 15 page or more then that because the web may have not enough back links or even none.

Describe the IT systems. Az nov 22

The IT system in this article is software that lets you restore your whole system back on the old or new computer in case your computer dies. But first, you need a "bootable disk".

How would this help you? These tools could help us by providing us with at least some more sense of security that what we barely have left now. Because we are often on the Internet, we are exposed to the danger of being seen and tracked by others. These tools help us stay invisible and informed. The use of encryption is used as well as proxies to hide user IP addresses. The free tools are basically for us to be aware of what is being tracked of our online activity, and how we can prevent it with the software.

Azman - Is this any good?

I don't think so. The site looks very unprofessional and it doesn't look legitimate at all. A company that is not well known rates most of the awards that they won. It could be pretty good software but since it's free, there will be downsides and restrictions to it; and users need to be careful when installing freeware.

What are the problems with doing everything on the cloud? may 19 az

Doing everything on the cloud is efficient in a way that we can work on from anywhere anytime as long as we have internet connection. However, when we don't have good internet connection, there is nothing we can do since everything we have done is stored on the cloud. . Internet data storing plans might also be an obstacle while operating on the cloud because the costs increase as more data is wanted to be stored on the cloud. Moreover, The cloud is not invincible to attacks so your data is not 100% safe. Having a backup saved on a physical hard drive is a must, cause you can't rely too much in the cloud (look what happen to Amazon and Sony).
