What is disk defragmentation?
Disk defragmentation describes the process of consolidating fragmented files on your computer's hard disk.
Fragmentation happens to a hard disk over time as you save, change, or delete files. The changes that you save to a file are often stored at a location on the hard disk that's different from the original file. Additional changes are saved to even more locations. Over time, both the file and the hard disk itself become fragmented, and your computer slows down as it has to look in many different places to open a file.
Disk Defragmenter is a tool that rearranges the data on your hard disk and reunites fragmented files so your computer can run more efficiently. In this version of Windows, Disk Defragmenter runs on a schedule so you don't have to remember to run it, although you can still run it manually or change the schedule it uses.
Improve performance by defragmenting your hard disk
Fragmentation makes your hard disk do extra work that can slow down your computer. Disk Defragmenter rearranges fragmented data so your hard disk can work more efficiently. Disk Defragmenter runs on a schedule, but you can also defragment your hard disk manually.
-
Open Disk Defragmenter.
If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
-
Click Defragment Now.
Disk Defragmenter might take from several minutes to a few hours to finish, depending on the size and degree of fragmentation of your hard disk. You can still use your computer during the defragmentation process.
Note
Check your hard disk for errors
You can help solve some computer problems and improve the performance of your computer by making sure that your hard disk has no errors.
-
Open My Computer.
-
Right-click the hard disk drive that you want to check, and then click Properties.
-
Click the Tools tab, and then, under Error-checking, click Check Now. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
To automatically repair problems with files and folders that the scan detects, select Automatically fix file system errors. Otherwise, the disk check will simply report problems but not fix them.
To perform a thorough disk check, select Scan for and attempt recovery of bad sectors. This scan attempts to find and repair physical errors on the hard disk itself, and it can take much longer to complete.
To check for both file errors and physical errors, select both Automatically fix file system errors and Scan for and attempt recovery of bad sectors.
-
Click Start.
Depending upon the size of your hard disk, this may take several minutes. For best results, don't use your computer for any other tasks while it's checking for errors.
Note
-
If you select Automatically fix file system errors for a disk that is in use (for example, the partition that contains Windows), you'll be prompted to reschedule the disk check for the next time you restart your computer.
Facebook aspires to be an environment where people can interact safely with their friends and the people around them. We have implemented many safety and privacy controls on Facebook as part of our goal to enable people to share their information with only the people they want to see it. We are constantly improving our systems for identifying and removing inappropriate content and people from the site.
Children under 13 years old are not permitted access to Facebook. In addition, parents of children 13 years and older should consider whether their child should be supervised during the child's use of the Facebook site.
Despite Facebook's safety and privacy controls, Facebook cannot guarantee that the site is entirely free of illegal, offensive, pornographic or otherwise inappropriate material, or that its members will not encounter inappropriate or illegal conduct from other members. Consequently, you may encounter such content and conduct. You can help Facebook by notifying us of any nudity, pornography, harassment or unwelcome contact by clicking on the "Report" link located on pages throughout the site. Facebook will use its best efforts to review reports made through this site reporting tool within 24 hours and remove any content that is deemed to have violated the Statement of Rights and Responsibilities. If warranted Facebook will also warn or disable the user responsible for posting the abusive content. Where complaints about nudity, pornography, harassment or unwelcome contact are made by independent email to abuse@facebook.com, Facebook will acknowledge receipt of the complaint and begin to address it within 24 hours. Facebook will respond to the reporter within 72 hours of receiving the email complaint to inform them of the steps Facebook has taken to address it.
We ask that all users to report suspicious people and inappropriate content they encounter on Facebook. We also strongly encourage users under the age of 18 to talk to a parent or a responsible adult immediately if someone online says or does something to make them feel uncomfortable or threatened in any way.
Remember that although using fake names is a violation of the Facebook Terms of Use, people are not always who they say they are. You should always be careful when sending friend requests to, or accepting friend requests from people you do not know in the real world. It is always risky to meet anyone in person whom you don't know through real world friends.
Always follow these important safety tips when using Facebook:
- Never share your password with anyone
- Adjust your privacy settings to match your level of comfort, and review them often
- Be cautious about posting and sharing personal information, especially information that could be used to identify you or locate you offline, such as your address or telephone number
- Report users and content that violate our Terms of Use
- Block and report anyone that sends you unwanted or inappropriate communications
The differences between Blogs and Forums : 
Forum is a discussion area on a website. Website members can post discussions and read and respond to posts by other forum members. Forum can be focused on nearly any subject and a sense of an online community, or virtual community, tends to develop among forum members.
Forums are created for discussion bewteen several people while Blogs are mainly designed for a single user input, with possibility for other people to comment.
So, Blogs are more like a simple homepage where other people may contribute with comments, but one person rules, blog owner, and blog owner can delete any comment s/he doesn't like. While, in forums, there could be hundreds of people posting topic messages and also adding comments ...
When people try to use forums for the purpose of writing a journal or news, their messages get lost in the stream of messages, making it hard to follow the story.
Also, people tend to post many short messages inside forums, while blogs are more used for posting longer messages (on average).
Blog owner can choose weather or not to make comments visible to the public.
Forum is also called a message board, discussion group, bulletin board or web forum. However, it differs from a blog, the name for a web log, as a blog is usually written by one user and usually only allows for the responses of others to the blog material. An Internet forum usually allows all members to make posts and start new topics.
Forum is also different from a chat room. Members in a chat room usually all chat or communicate at the same time, while members in an Internet forum post messages to be read by others whenever they happen to log on. Internet forums also tend to be more topic-focused than chat rooms.
