The document discusses various technologies used in televisions in 2012. LCD TVs made up 87.3% of worldwide TV shipments, while plasma TVs (PDTV) accounted for 5.7%. It also discusses social aspects of television such as its role in socialization and the incorporation of social media. Environmental concerns around electronic waste from outdated TVs are also mentioned.

Social aspects and effects on children
Television has played a pivotal role in the socialization of the 20th and 21st centuries. There are
many aspects of television that can be addressed, including media violence research. In 2010
theiPlayer incorporated a social media aspect to its internet television service,
including Facebook and Twitter.[52] Other devices that allow interactivity such as the Apple
TV, Google TV andChromecast, have made possible for users to access content through the
internet on their TVs and log in social media websites like Youtube. Also, the use of the
television for video games, especially games such as the Wii, has contributed to a growing
kinaesthetic connection between television and viewers.[53]
Environmental aspects
With high lead content in CRTs, and the rapid diffusion of new, flat-panel display technologies,
some of which (LCDs) use lamps which contain mercury, there is growing concern
about electronic waste from discarded televisions. Related occupational health concerns exist,
as well, for disassemblers removing copper wiring and other materials from CRTs. Further
environmental concerns related to television design and use relate to the devices']

3. HOME
THEATER
A home theater or home theatre is a theater built in a home, designed to mimic (or exceed)
commercial theater performance and feeling, more commonly known as a home cinema. Today,
home cinema implies a real "cinema experience" at a private home.
•Home cinema, commonly referred to as home theater or home theatre, are home entertainment
set-ups that seek to reproduce movie theater video and audio feeling in a private home
•Backyard theater, home theater in the backyard. Depending on the space available, it may simply
be a temporary version with foldable screen, a projector and couple of speakers, or a permanent
fixture with huge screens and dedicated audio set up poolside. Due to the outdoor nature, it is
quite popular with BBQ parties and pool parties.
•Home theater in a box, HTIB is an modestly-priced integrated home theater package which
"bundles" together a combination DVD-Video or Blu-ray Disc player and multi-channel amplifier
(which includes a surround sound decoder, a radio tuner, and other features), speaker wires,
connection cables, a remote control, a set of five or more surround sound speakers (or more
rarely, just left and right speakers) and a low-frequency subwoofer
•AV receiver, often referred to as home theater systems or home entertainment system
•Front video projector and projector screen, often referred to as a home theatre or Home cinema
•Home theater PC, HTPC or media PC is a convergence device that combines the functions of a

4. COMPUTER
A computer is a general purpose device that can be programmed to carry out a set of arithmetic or logical
operations. Since a sequence of operations can be readily changed, the computer can solve more than one
kind of problem.
Conventionally, a computer consists of at least one processing element, typically a central processing
unit (CPU), and some form ofmemory. The processing element carries out arithmetic and logic operations,
and a sequencing and control unit can change the order of operations in response to stored information.
Peripheral devices allow information to be retrieved from an external source, and the result of operations
In World War II, mechanical analog computers were used for specialized military applications. During this
time the first electronicdigital computers were developed. Originally they were the size of a large room,
consuming as much power as several hundred modernpersonal computers (PCs).[1]
Modern computers based on integrated circuits are millions to billions of times more capable than the early
machines, and occupy a fraction of the space.[2] Simple computers are small enough to fit into mobile
devices, and mobile computers can be powered by smallbatteries. Personal computers in their various forms
are icons of the Information Age and are what most people think of as “computers.” However,
the embedded computers found in many devices from MP3 players to fighter aircraft and from toys
to industrial robots are the most numerous.

5. MOBILE
(I-PHONE)
Mobile phones are used for a variety of purposes, including keeping in touch with family
members, conducting business, and having access to a telephone in the event of an emergency.
Some people carry more than one cell phone for different purposes, such as for business and
personal use. Multiple SIM cards may also be used to take advantage of the benefits of different
calling plans—a particular plan might provide cheaper local calls, long-distance calls,
international calls, or roaming. The mobile phone has also been used in a variety of diverse
contexts in society, for example:
A study by Motorola found that one in ten cell phone subscribers have a second phone that
often is kept secret from other family members. These phones may be used to engage in
activities including extramarital affairs or clandestine business dealings.[24]
Some organizations assist victims of domestic violence by providing mobile phones for use in
emergencies. They are often refurbished phones.[25]
The advent of widespread text messaging has resulted in the cell phone novel; the first literary
genre to emerge from the cellular age via text messaging to a website that collects the novels as
a whole.[26]

6. AIR
CONDITIONER
Air conditioning (often referred to as aircon, AC or A/C) is the process of altering the properties
of air (primarily temperature andhumidity) to more favourable conditions. More generally, air conditioning
can refer to any form of technological cooling, heating, ventilation, or disinfection that modifies the
condition of air.[1]
An air conditioner is a major or home appliance, system, or mechanism designed to change the air
temperature and humidity within an area (used for cooling and sometimes heating depending on the air
properties at a given time). The cooling is typically done using a simplerefrigeration cycle, but
sometimes evaporation is used, commonly for comfort cooling in buildings and motor vehicles.
In construction, a complete system of heating, ventilation and air conditioning is referred to as "HVAC".
Air conditioning can also be provided by a simple process called free cooling which uses pumps to circulate a
coolant (typically water or a glycol mix) from a cold source, which in turn acts as a heat sink for the energy
that is removed from the cooled space. Free cooling systems can have very high efficiencies, and are
sometimes combined with seasonal thermal energy storage (STES) so the cold of winter can be used for
summer air conditioning. Common storage media are deep aquifers or a natural underground rock mass
accessed via a cluster of small-diameter, heat exchanger equipped boreholes. Some systems with small
storage are hybrids, using free cooling early in the cooling season, and later employing a heat pump to chill
the circulation coming from the storage. The heat pump is added-in because the temperature of the storage
gradually increase during the cooling season, thereby declining in effectiveness. Free cooling and hybrid
systems are mature technology.[2]
