LESSON 3: COMMUNICATIONS AND NETWORK
Communications technologies are everywhere. Many require that you subscribe to an Internet service
provider. With others, an organization such as a business or school provides communications services
to employees, students, or customers.
Wi-Fi and Bluetooth are both hot spot technologies. A hot spot is a wireless network that provides
Internet connections to mobile computers and devices. Wi-Fi hot spots provide wireless network
connections to users in public locations, such as airports and airplanes, train stations, hotels, convention
centers, schools, campgrounds, marinas, shopping malls, bookstores, libraries, restaurants, coffee
shops, and more. Bluetooth hot spots provide location-based services, such as sending coupons or
menus, to users whose Bluetooth-enabled devices enter the coverage rang

3.3 Network
Many homes and most businesses and schools network their computers and devices. Most allow users
to connect their computers wirelessly to the network. Users often are required to sign in to, or log on, a
network, which means they enter a user name and password (or other credentials) to access the
network and its resources.
Home Networks
Home networks usually are small, existing within a single structure, and use wireless technologies. You
do not need extensive knowledge of networks to set up a home network. You will need a
communications device, such as a router, which usually includes setup instructions. Most operating
systems also provide tools enabling you easily to connect all the computers and devices in your house.

Business Networks
• Share hardware. In a networked environment, each computer on the network can access the
hardware on the network, instead of providing each user with the same piece of hardware. For
example, computer and mobile device users can access the laser printer on the network, as
they need it.
• Share data, information, and software. In a networked environment, any authorized
computer user can access data, information, and software stored on other computers on the
network. A large company, for example, might have a database of customer information that
any authorized user can access.
Education

courses provide time, distance, and place advantages for students who live far from a campus or work
full time. A few schools offer entire degrees online. National and international companies offer distance
learning training because it eliminates the costs of airfare, hotels and meals for centralized training
sessions.

Retail

Many mobile apps make your shopping experience more convenient. Some enable you to manage
rewards, use coupons, locate stores, or pay for goods and services directly from your phone or other
mobile device. Other mobile apps will check a product’s price and availability at stores in your local area
or online.
Entertainment
Health Care
• Hospitals and doctors use computers and mobile devices to maintain and access patient
records.
• Computers and mobile devices monitor patients’ vital signs in hospital rooms and at home;
patients use computers to manage health conditions, such as diabetes.
• Robots deliver medication to nurses’ stations in hospitals.
• Computers and computerized devices assist doctor, nurses, and technicians with medical tests.
• Doctors use the web and medical software to assist with researching and diagnosing health
conditions.
• Doctors use email, text messaging, and other communications services to correspond with
patients.
• Patients use computers and mobile devices to refill prescriptions, and pharmacists use
computers to file insurance claims and provide customers with vital information about their
medications.
• Surgeons implant computerized devices, such as pacemakers, that allow patients to live longer.
• Surgeons use computer-controlled devices to provide them with greater precision during
operations, such as for laser eye surgery and robot-assisted heart surgery.
• Medical staff create labels for medicine, hospital ID bracelets, and more, enabling staff to verify
dosage and access patient records by scanning the label.

Science
A neural network is a system that attempts to imitate the behavior of the human brain. Scientists create
neural networks by connecting thousands of processors together much like the neurons in the brain are
connected. The capability of a personal computer to recognize spoken words is a direct result of
scientific experimentation with neural networks.
Travel
In preparation for a trip, you may need to reserve a car, hotel or flight. Many websites offer these
services to the public where you can research for and compare flights and prices, order airline tickets
or reserve a rental car. You also can print driving directions and maps from the web.
Publishing
Many publishers of books, magazines, newspapers, music, film and video make their works available
online. Organizations and individuals publish their thoughts and ideas using a blog, pod cast, or wiki.

b.) Podcasts are a popular way to distribute b
audio or video on the web. A podcast is
recorded media that users can download or
stream to a computer or portable media
player. Examples of podcasts include
lectures, political messages, radio shows,
and commentaries. Podcasters register their
podcasts so that subscribers can select
content to automatically download when
they are connected.
c
c) A wiki is a collaborative website that allows
users to create, add to, modify, or delete the
content via their browser. Many wikis are
open to modification by the general public.
The difference between a wiki and a blog is
that users cannot modify original posts made
by a blogger.
