Here are the most important using of social networking sites as facebook, my space , linkedIn.

Facebook is a social networking service launched in February 2004, owned and operated by Facebook, Inc.[4] As of September 2012, Facebook has over one billion active users,[5] more than half of them using Facebook on a mobile device.[6] Users must register before using the site, after which they may create a personal profile, add other users as friends, and exchange messages, including automatic notifications when they update their profile. Additionally, users may join common-interest user groups, organized by workplace, school or college, or other characteristics, and categorize their friends into lists such as "People From Work" or "Close Friends".

and this is the rule of using the facebook:

RULE 1: Project yourself in a manner others would want to be associated with.

RULES 2, 3, and 4: Don’t post anything that will hurt a friend’s image, career, or relationship.

RULE 5: Respond immediately when someone leaves you a Facebook message.

RULE 6: Expect an immediate response from others when you post on their profiles.

RULE 7: Use privacy settings to control each friend’s level of access to your profile.

RULE 8: Share information with close friends before posting it on Facebook.

RULE 9: Delete or block anyone who posts something that compromises your image.

RULE 10: Apply offline social rules to your Facebook interactions.

Pros and Cons of Facebook for Individuals

There are obviously two sides to this argument, and it all depends on what your opinions are. People who like Facebook can spend hours on it browsing through other people's profiles, whereas some people cannot even stand the sight of it, even though they know how to use the site wisely. Here are some of the well-known pros of Facebook. You have the ability to find old friends and reconnect with them. You can keep in touch with your friends, no matter how far apart you'll are physically. You can keep your friends and family members updated about what is happening in your life. You can promote yourself and any other work that you do. You can make many new like-minded friends by joining various groups and communities. You can share your favorite music and videos with your friends. You can play many different games and use many different applications. You can communicate with your friends at any time you want. To balance out these advantages, there are bound to be some cons of as well, and these are what deter many people from joining the website. You will get bombarded with unwanted friend requests from many unknown people. Your friends and family members will be able to snoop around and know what is happening in your life at all times. Your pictures could be misused. You might mistakenly befriend an individual with dishonorable intentions. You will get unwanted newsfeeds about every single activity that your friends perform on Facebook. Your friends will get newsfeeds about every single activity that you perform as well. You will get bombarded by spam and annoying advertisements from time to time. You will witness unnecessary dramatization of unimportant occurrences in your friends lives. Anyone will be able to see your information and pictures, if you do not update your privacy settings regularly. Your friends may tag you in a picture that you do not want others to see. Applications will ask you for many details that you would not normally give out. You will waste many hours because it is addictive for most people.

My Speace:

Big Network: If you are looking to meet or find people MySpace is a good place to look. There are lots of people on MySpace so finding people there is easy.

and this is some rules of using my space:

Rule 1 : No matter what the bulletins say, no girl is going to pop up next to you in the middle of the night and kill you.

Rule 2 : If you don’t post that bulletin it in no way affects your love life. You affect that in either a good or bad way, you’re to blame

Rule 3 : When you have new pictures don’t post numerous bulletins stating that you have new pictures and to comment them. Your real friends will see the first and comment them if they like.

Rule 4 :To all those of you with 5,000 friends, NOBODY has that many friends you’re what’s known as a myspace whore. You don’t know them all, and you’ll never meet even 200 of them. Rule 5 : Videos are nice but why have 4, 5 or more video’s in there? They all play at the same time, and slow down your page.

Rule 6 : Stop begging people to put you in their top 8. There’s a reason you’re not in it. That is they have 8 friends they like more than you and get over it!

Pros and Cons of myspeace for Individuals

1.My Space can be a relatively safe place for older teens and young adults to share information about themselves and to meet new people. People can share their views, interests and passions.

2.Use of MySpace works well for younger people who don’t use e-mail very often but enjoy instant messaging.

3.MySpace provides young people a site where they can give and receive feedback.

4. MySpace can be dangerous because there are sexual predators who use the site to seduce young people.

5.Many parents are not aware of the dangers of MySpace. There are even parents who do not realize their teens have a profile on MySpace or what information may have been given.

6.Advertisers use MySpace as a way to make a lot of money. Some of the sites that have advertising are used in conjunction with sexual content. This means the advertisers are making money from ads that promote pornography.

7.MySpace tries to have controls and it has monitoring procedures in place but many things have slipped through. There are groups that promote homosexual practices as well as groups that show pornographic photos.

8.MySpace can not control the people who lie about their age or give other false information. It also can’t do anything about teens who are 14 and choose to correspond with people who are 10, 20 or 30 years older.

linkedIn:

LinkedIn: is a social networking website for people in professional occupations. Founded in December 2002 and launched on May 5, 2003, it is mainly used for professional networking. As of June 2012, LinkedIn reports more than 175 million registered users in more than 200 countries and territories. The site is available in English, French, German, Italian, Portuguese, Spanish, Dutch, Swedish, Romanian, Russian language, Turkish language, Japanese language, Czech, Polish, Korean, Indonesian, and Malay. Quantcast reports LinkedIn has 21.4 million monthly unique U.S. visitors and 47.6 million globally. In June 2011, LinkedIn had 33.9 million unique visitors, up 63 percent from a year earlier and surpassing MySpace. LinkedIn filed for an initial public offering in January 2011 and traded its first shares on May 19, 2011, under the NYSE symbol "LNKD".

and this is some rules of using linkedIn:

Rule 1 :Only do what you’d be comfortable doing in person. Rule 2 :Be personal. Rule 3 :Mind your Ps and Qs. Rule 4 :Don’t cause a traffic jam. Rule 5 :Give recommendations. Rule 6 :Ask for recommendations strategically. Rule 7 :Keep it professional. Rule 8 :Avoid making it all about you.

Pros and Cons of linkedIn :

The Pros 1.A job seeker can quickly build their reputation for having skills relevant to their job function and industry without putting a great imposition on their contacts. 2.Having skills endorsements may help with profile optimization and SEO making it easier for people to be found. 3.Colleagues can recommend additional skills that may be added to a user’s profile. This is a nice way for people to help each other build a more digitally distinct presence and generate additional interest from recruiters and employers. 4.Endorsements help job seekers by offering more regular prompting to examine the skills section, an area of the LinkedIn profile that has become increasingly more important over the past few months. The Cons 1.Endorsements might not be viewed with the same “street cred” as recommendations. Someone willing to give you a recommendation is really taking the time to advocate for you and document specifically the value you bring to an organization. Someone offering an endorsement is basically “checking a box”. 2.The endorsements feature may not be in synch with the LinkedIn culture. The feature in some ways mimics a Facebook “Like.” But on Facebook users “like” a company or product. This is consistent with the Facebook culture of sharing. But on LinkedIn you are “liking” a person. It just feels a bit contrived to me. 3.Users may get bombarded with requests from people asking for endorsements since LinkedIn has made it so easy to keep clicking on user profiles to make requests. What used to require some effort on the part of the requester has been automated to the point that hundreds of requests could probably be sent out in minutes. 4.Endorsements may actually erode the networking process rather than build it. Authentic relationships are built over time. You need to feel very confident in your relationship with someone in order to request a recommendation. I don’t believe there is the same level of entry for requesting endorsements. 5.Endorsements smack of a “you scratch my back I’ll scratch yours” mentality. Just because someone gives you a recommendation it doesn’t mean that it is appropriate to return the favor. But with endorsements those lines may be blurred. Be prepared to see a lot of reciprocal endorsements on LinkedIn over the next few months.

solid state
 Solid state,  at its most basic level, means "no moving parts." Therefore, solid state electronic devices are made up of solid components that do not move. Some examples include computer motherboards and integrated circuits. Devices that use only solid state parts, such as television sets, speakers, and digital watches, are often referred to as solid state products. Flash memory devices are solid state products, while hard drives are not. This is because hard drives use a spinning disk and moving drive head to read and write data, while flash memory uses electric charges to perform the same functions. For this reason, flash memory devices are seen as more durable than hard drives. This is why flash memory is often used in products such as portable MP3 players and digital cameras. Because solid state devices have no moving parts, they are less likely to break down than devices that have mobile mechanisms. For this reason, it is often more worthwhile to buy an extended warranty on electronics that have moving parts than those that do not. That is something you may want to think about next time you are shopping.

 The solid state PC   A silent PC is one that makes absolutely no noise, and by necessity has no moving parts (including fans). Such systems usually use very low-end hardware limited to trivial tasks such as running a cash register. The system introduced today, a Solid-State PC (SSPC) is a powerful quad-core i5 PC which runs most software faster than the majority of modern PCs, yet uses less than 25W idle. A story familiar to many computer buyers: You go to your local technology outlet to pick up a shiny, powerful new desktop computer. While browsing available models you ask, how fast is the CPU? How much music can it store? How quickly does it start up? You take it home, excitedly hook it up, and find that it blazing…rather loud, actually. Memory, hard drive space, processor speed — these numbers are easily found both at the store or online, and savvy shoppers know they are important. An often forgotten question, one that can be difficult to answer, is “how loud is it?” It isn’t just PCs used for home theater (HTPCs) which need to keep the noise down — many computers are just distractingly loud, annoying house guests, drowning out subtleties while playing music, or just making it difficult to concentrate. Some manufacturers do a good job of sound deadening. Recent models of Dell’s Optiplex, for example, use a main fan positioned cleverly in the center of the case, allowing the space inside to absorb the wind noise generated by the fan. Other manufacturers don’t do quite as well. Many designs, for example, not only use loud fans positioned against the walls of the case– they change the fan speed rapidly (and unnecessarily) as CPU usage changes. The resulting noise is difficult to ignore because it is inconsistent. No matter how well designed a PC, silent it is not. Hard drives, component cooling, and power supplies are sources not only of unwanted sound, but the air they move contributes to dust build-up within the case.

 Types of solid state storage 

http://computer.howstuffworks.com/removable-storage9.htm

Solid-state storage can be found in three form factors: solid state drives (SSD), solid state cards (SSC), solid state modules (SSM). An important advantage of solid-state storage is the fact that it contains no mechanical parts, allowing data transfer to and from storage media to take place at a much higher speed and providing a more predictable lifespan for the storage media. In addition to providing faster and more consistent input/output (I/O) times, solid-state storage media offers the same levels of data integrity and endurance as other electronic devices and requires less power and cooling than its electromechanical equivalents. It also generally weighs less. Although solid-state storage technology is not new, interest in how the technology can be used to improve enterprise storage has been relatively recent. Since the turn of this century, processor speeds have continued to increase dramatically while read and write times for mechanical hard disks have not. Today’s CPUs can process data much faster than hard disk drive storage can supply it. The resulting lag time is known as latency, and one way enterprise administrators have traditionally dealt with high storage latency is by short-strokingthe disk drives. Short-stroking is done by deliberately limiting the disk drive capacity so that the disk drive actuator has to move the heads across a smaller number of tracks, reducing seek time. Environments that implement short-stroking typically have to make up for the reduced capacity utilized in each disk drive by increasing the number of disk drives in these configurations. By contrast, SSS devices have zero seek time so their latencies are considerably less, which makes them faster than hard disk drives. In the enterprise, solid-state storage technology is being used for primary storage but also ascache in front of traditional spinning disks, introducing a new layer between the processor and storage. Some industry experts predict that solid-state storage will eventually replace hard disk storage if silicon factories can meet the increasing demand for product and the price for SSS continues to decline. As of this writing, a 2 terabyte (TB) RAM-based solid-state external storage system would cost approximately six hundred thousand dollars. In contrast, a mechanical hard drive with 2 TB of storage can be purchased for less than $150. There are two types of solid state systems: flash memory-based systems and RAM-based systems. There are also two types of flash memory: NAND flash and NOR flash.
