QUESTION NO.5:- WRITE A NOTE ON THE FOLLOWING TOPICS:-
 MULTIMEDIA PROJECTOR
 ELECTRONIC MAIL (EMAIL) .
 SPEECH RECOGNITION DEVICES
 SOCIAL NETWORKING WEBSITES
Answer:- .
MULTIMEDIA PROJECTOR:-
The term multimedia projector is perhaps the broadest, most encompassing term in the projector world, and implies that projectors have evolved to do pretty much everything!
Technically, multimedia projectors range from the smallest pico projectors to the heftiest 100 lbs.+ large venue projectors. Therefore, to put it simply, basically every projector is a multimedia projector nowadays. Although the category of multimedia projectors is a giant basket that includes virtually every projector out there, it is still a popular search engine term.
The term implies flexibility. In the early days, the first projectors were video signal only, no ability to work with, say, a computer input. There have even been a few specialty projectors, I believe, that have only been PC projectors without a video. There are projectors that don’t have video but just computer—just for data.
Today’s multimedia projectors start entry level with SVGA resolution projectors from under $500, and move up into models with resolutions all the way up to 1080p and WUXGA+ (1920×1200). From a compatibility standpoint, most offer HDMI or DVI inputs, as well as all the older favorites and standards including VGA and composite and S-videos. Even the pico projectors, which are all multimedia, are starting to sport HDMI. Almost all that are for business and education have a built in speaker or two. Most multimedia projectors have 5-8 different inputs. Many models now offer wired, wireless, or both types of networking, and some can even present from content passed along the network. Some with wireless networking can even switch between many different computers (laptops) in the room! Talk about versatility. A new feature of streaming data off the internet has allowed for its own category in the world of multimedia projectors. We are starting to see projectors that don’t need computers or Blu-ray players, but that can stream directly from intent!
ELECTRONIC MAIL (EMAIL):-
Electronic mail, most commonly referred to as email or e-mail since ca. 1993,[2] is a method of exchanging digital messages from an author to one or more recipients. Modern email operates across the Internet or other computer networks. Some early email systems required that the author and the recipient both be online at the same time, in common with instant messaging. Today’s email systems are based on a store-and-forward model. Email servers accept, forward, deliver, and store messages. Neither the users nor their computers are required to be online simultaneously; they need connect only briefly, typically to a mail server, for as long as it takes to send or receive messages.

Historically, the term electronic mail was used generically for any electronic document transmission. For example, several writers in the early 1970s used the term to describe fax document transmission.[3][4] As a result, it is difficult to find the first citation for the use of the term with the more specific meaning it has today.

An Internet email message [NB 1] consists of three components, the message envelope, the message header, and the message body. The message header contains control information, including, minimally, an originator’s email address and one or more recipient addresses. Usually descriptive information is also added, such as a subject header field and a message submission date/time stamp. Originally a text-only (ASCII) communications medium, Internet email was extended to carry, e.g. text in other character sets, multi-media content attachments, a process standardized in RFC 2045 through 2049. Collectively, these RFCs have come to be called Multipurpose Internet Mail Extensions (MIME). Subsequent RFC’s have proposed standards for internationalized email addresses using UTF-8.
Electronic mail predates the inception of the Internet and was in fact a crucial tool in creating it,[51 but the history of modern, global Internet email services reaches back to the early ARPANET. Standards for encoding email messages were proposed as early as 1973 (RFC 561). Conversion from ARPANET to the Internet in the early 1980s produced the core of the current services. An email sent in the early 1970s looks quite similar to a basic text message sent on the Internet today.
Email is an information and communications technology. It uses technology to communicate a digital message over the Internet. Users use email differently, based on how they think about it. There are many software platforms available to send and receive. Popular email platforms include Gmail, Hotmail, Yahoo! Mail, Outlook, and many others. Network-based email was initially exchanged on the ARPANET in extensions to the File Transfer Protocol (FTP), but is now carried by the Simple Mail Transfer Protocol (SMTP), first published as Internet standard 10 (RFC 821) in 1982. In the process of transporting email messages between systems, SMTP communicates delivery parameters using a message envelope separate from the message (header and body) itself.
SPEECH RECOGNITION DEVICE:-
In computer science and electrical engineering, speech recognition (SR) is the translation of spoken words into text. It is also known as “automatic speech recognition” (ASR), “computer speech recognition”, or just “speech to text” (STT).
Alternatively referred to as speech recognition, voice recognition is an ability of a computer, computer software program, or hardware device to decode the human voice into digitized speech that can be interpreted by the computer or hardware device. Voice recognition is commonly used to operate a device, perform commands, or write without having to operate a keyboard, mouse, or press any buttons. Today, this is done on a computer with automatic speech recognition (ASR) software programs. Many ASR programs require the user to “train” the ASR program to recognize their voice so that it can more accurately convert the speech to text. For example, a user could say “open Internet” and the computer would open an Internet browser and allow that user to browse the Internet.
The first ASR device was used in 1952 and recognized single digits spoken by a user (it was not computer driven). Today, ASR programs are used in many industries, including Healthcare, Military (i.e. F-16 fighter jets and helicopters), Telecommunications and Personal computing (i.e. hands free computing). Smartphone’s and mobile devices are in the middle of major innovations in technology to provide hands-free access to features and navigation, often called voice commands, voice-enabled, voice actions or speech recognition. This technology has major implications for use by people who have disabilities as assistive technology. As long as a user has a strong, clear voice, these devices become easier to use and give increased access to use of the Internet, use of mobile devices and communication accessibility. Currently available devices are largely speaker-dependent (recognize speech of only one or two persons) and can recognize discrete speech (speech with pauses between words) better than the normal (continuous) speech. Their major applications are in assistive technology for helping people in working around their disabilities. Not to be confused with voice recognition which is used mainly in security devices.

SOCIAL NETWORKING WEBSITES:-
Social networking is the grouping of individuals into specific groups, like small rural communities or a neighborhood subdivision, if you will. Although social networking is possible in person, especially in the workplace, universities, and high schools, it is most popular online. This is because unlike most high schools, colleges, or workplaces, the internet is filled with millions of individuals who are looking to meet other people, to gather and share first-hand information and experiences about cooking, golfing, gardening, developing friendships professional alliances, finding employment, business-to-business marketing and even groups sharing information about baking cookies to the Thrive Movement. The topics and interests are as varied and rich as the story of our universe. When it comes to online social networking, websites are commonly used. These websites are known as social sites. Social networking websites function like an online community of internet users. Depending on the website in question, many of these online community members share common interests in hobbies, religion, politics and alternative lifestyles. Once you are granted access to a social networking website you can begin to socialize. This socialization may include reading the profile pages of other members and possibly even contacting them.
