How to Make Your Computer Run Faster

Open up the start menu and click ‘Control Panel’
Double click on ‘Add or Remove programs’
Look at the list. Chances are there’s a lot of things you’d forgotten on there.
Select a program you don’t need any longer by clicking on it.
Click on the button at the top that says ‘Uninstall’. (Note, sometimes it says ‘Uninstall/Repair, click on that one if plain old ‘uninstall’ is unavailable).
Follow what the computer tells you. Depending on the program a different menu will come up, but common sense usually tells you what to do.
Delete every single file that you don’t need.
Double check the list to make sure you haven’t missed anything that takes up a lot of memory but you never actually use.
Open all the programs like Word Processor, Powerpoint, Paint etc, and check all the saved files there, deleting any you don’t need by right clicking on the file name and pressing delete.
Right-click on the recycling bin icon on your desktop and press ‘Empty Recycling Bin’. The pop-up that says ‘Do you want to permanently delete these ___ files?’ can often be a ridiculously large number.
Install a good anti-virus program. The best free one is AVG, but you can pay for the best anti-spyware programs.
Restart your computer/laptop. Often to notice a change the computer needs to start up again.
after you do all of that go to ,,,, and click .choose the drive you want to defrag.usually its the C. drive. first it analyzes and then defrags.you should notice a huge differince in how fast programs run.
If you use a Windows operating system, Windows saves a file of the program you are using to make it start up faster. After years of using your computer this folder, Prefetch folder, gets filled with unused programs. This command prompt will delete this folder for you and get rid of idle processes. Simply open a notepad file, copy and paste this into line 1 without the quotes “del C:\Windows\Prefetch\*.* /Q” hit enter and on line 2 paste “Rundll32.exe advapi32.dll,ProcessIdleTasks”. Then go to save as, name it whatever you want, I chose a simple name as ‘faster’. Make sure after the name it does not have faster.txt, you need to put faster.bat (The .bat extension will run it as a batch file. Once it’s saved you can go ahead and run it! In a few moments the command prompt will dissappear and your programs should run more smoothly.
Repeat this every month or so, depending on how much you download files/create documents/powerpoints or whatever.

Audio and Multimedia

Multimedia content on the Web, by its definition – including or involving the use of several media – would seem to be inherently accessible or easily made accessible.

However, if the information is audio, such as a RealAudio feed from a news conference or the proceedings in a courtroom, a person who is deaf or hard of hearing cannot access that content unless provision is made for a visual presentation of audio content. Similarly, if the content is pure video, a blind person or a person with severe vision loss will miss the message without the important information in the video being described.

Remember from Section 2 that to be compliant with Section 508, you must include text equivalents for all non-text content. Besides including alternative text for images and image map areas, you need to provide textual equivalents for audio and more generally for multimedia content.

Some Definitions
A transcript of audio content is a word-for-word textual representation of the audio, including descriptions of non-text sounds like “laughter” or “thunder.” Transcripts of audio content are valuable not only for persons with disabilities but in addition, they permit searching and indexing of that content which is not possible with just the audio. “Not possible” is, of course too strong. Search engines could, if they wanted, employ voice recognition to audio files, and index that information – but they don’t.

When a transcript of the audio part of an audio-visual (multimedia) presentation is displayed synchronously with the audio-visual presentation, it is called captioning. When speaking of TV captioning, open captions are those in which the text is always present on the screen and closed captions are those viewers can choose to display or not.

Descriptive video or described video intersperses explanations of important video with the normal audio of a multimedia presentation. These descriptions are also called audio descriptions.

Section 508 Requirement for Transcripts
The availability of a transcript of audio content satisfies the requirement of the first Section 508 standard formulated by the Access Board.

Digital Media and the Internet

Digital media, also known as “new media,” comprise content created, disseminated, and/or stored using digital computers or mobile devices (video games, blogs, etc.), as well as their physical embodiment (DVDs, flash memory sticks, etc.). Digital media are often defined in contrast to “analog media,” new media in contrast to “mass media.”The history of digital media documents the move of computers from glorified calculators to devices for human communications, entertainment, and creative production, linking digital media to earlier interactive machines and media.Central to this move and to computers more generally is memory: one of the definitions of digital media is digital storage device. The first clear articulation of computer memory to store both data and instructions was John von Neumann’s 1945 First draft of a report on the EDVAC, in which he compared vacuum tubes to human neurons. More concretely, J. Presper Eckert developed a mercury signal delay tube to produce “regenerative memory.” Static magnetic memory – based on recording technology developed in Germany during World War II – was first used in 1952 for an MIT test machine. The term digital media, however, does not simply mean digital storage: not only do early forms of digital storage (CRTs, ferrite magnetic coated tapes, and so on) not register now as digital media, the emergence of digital media effected the notion

Electronic Media History

As anyone who knows me or my writing is aware, this has been a long-term teaching and research interest…surely since I was first exposed to the history of radio and television in the mid-1960s. My prime focus is more on development of technology, policy and the industry rather than programs. There are scads of websites on all these topics—here are just a handful (including several important archives) on both domestic and international radio and television. They are followed by some suggested books of value.

ELECTRONIC MEDIA WAR

People at the helm of affairs have finally arrived to the conclusion that keeping the private sector away from the ambit of the electronic media may not be possible any more in the face of global proliferation of Information and Satellite technology. As a result, an array of satellite tv channels have started invading the target countries with social, political and economic interests..

Electronic media

is mediathat uses electtronics or electromechanical energy for the end user (audience) to access the content.
This is in contrast to static media (mainly print media), which are most often created electronically, but don’t require electronics to be accessed by the end user in the printed form. The primary electronic media sources familiar to the general public are better known as video recordings, audio recordings, multimedia presentations , slide presentations. CD-ROM & Online Content. Most new media are in the form of digital media. However, electronic media may be in either analog or digital. Electronic media is the best class ever.

Types of Print Media

Print media includes many different ways in which an advertiser can reach a target group. Here are some of the different types of print media.

The Importance of Media Education

Media education can help young people put current images and messages about Aboriginal people into perspective by helping them understand how the media work, why stereotyping exists, how decisions are made, and why “it matters who makes it.”Media education is not about learning the right answers; it’s about consuming media images with an active, critical mind and asking the right questions.
