14.0 Introduction
This unit introduces you to the E-mail services. It starts off
with a brief explanation of E-mail and its advantages. The later partunit deals with other areas of modern technology.
14.1 Objectives
By the end of this unit, you will be able to:
Explain what E-mail is and how it works.
Discuss the merit of E-mail in our society.
Identify other forms of information technology such as the
intelligent automobile, police information system etc.
Discuss the problems associated with Internet.
14.2 Electronic Mail
This is a computer to computer exchange of message with person to person messaging, documents and sharing. It is a method of creating
and sending messages electronically to one or more individuals.
These messages are stored in the destination mailbox until the receiver is ready to read them. Both the sender and receiver do not
necessarily need to be on the same network machine.
Advantages of E-mail include:
a. E-mail is very fast
b
E-mail is entirely electronic and doesn’t require that papercopies of the message be created unless the recipient desires a printed
version.
c. E-mail is convenient
d Materials in E-mail can easily be copied from other documents
to the clipboard and inserted as part of e-mail message.
14.3 Transport Industry
You cannot see, or smell nuclear radiation, but it’s deadly. There are
many health hazards that can be caused by the transport industry thatit can reduce by using Transport Environmental Decision Support System (TEDSS) to assist in creating an evacuation plan in case of a
nuclear power plan disaster there. For TEDSS to be effective, it has
to use the following information:
shelters.
(1)
(2) (3)(4) (5)
(6) (7) (8)
The behaviour of radioactive gasses, such as dispersion rates.
Highway system characteristics, such as number of lanes.
Population distributions, such as densities and the location of the people with disabilities.
Current weather conditions, such as wind direction.
Evacuation routes and paths from any origin to assigned Projected volumes of traffic on he highway system.
Highways that may become severely blocked by radiation.
Time that will have elapsed before the last vehicle clears the area, (Haag, Cummings and Dawkins, (1998:)
Activity 14.1
On your own make a list of the various ways in which Nigeria can benefit from advances in the Technology of the 21st Century.
14.4 Other areas of Modern Technology 14.4.1 The Intelligent Automobile
This involves monitoring engine performance of the air-fuel ratio, spark advance idle sped, oil transmission fluid, and coolant levels,
entertainment systems and on-board diagnostic systems.
14.4.2 Other Advanced Applications of Modern Technology
These include electronic navigation system, keyless locking and communication systems. Physical distribution of reight to include computerized freight rates and payment systems such as rate analysis,
automatic freight payment and report generation. Computerized shipment-tracking system to include monitors step-by-step progress of
particular shipment assists in processing a particular shipment.
Computerized mileage/route system to include mile-marker.
The rail and shipping industries to include: railroad applications such
as automated car identification system. Centralized traffic control system and computer-aided dispatch system which can monitor the
street lights, and traffic showing different colorful signals to motorists
and pedestrians that green means go, red means stop and appear means get ready. Shipping applications to include design and manufacturing of ships, computer assisted navigation, computer
monitoring of ship engines, cargo, fuel and supplies.
14.4.3 Police Information System
This is the heart of all police information network that can be used to prevent crime, it contains police information of a national basis to
track records of conviction, records of stolen property, and other
reports.
14.4.4 Problems of Internet
The Internet present many problems to the business users, largely stemming from the fact that most of the technology and
functions are relatively immature. These problems range from:
* Security information on Internet Electronic links tends to be
exposed to attacks from both thieves and vandals.
Internet
hackers have found ways to steal from both passwords as they
*
pass through.
Technology Problem. Lack of standards allowing incompatible
ways exists to access the net, allowing specific users to
perform certain function. Lack of standards also affects the ability of organization to establish a stable link to the Internet.
Sending graphics on Internet is also a problem because of low
*
speed. Phone network not reliable, speed of data transfer differ and slower than US.
Legal Issues. Laws governing electronic commerce are mostly non-existent or are just being written. Legislatures, courts, and
*
international agreements will have to settle such. Discriminate copy of documents without permission.
Traditional Internet Culture. The Internet had its origins as a
scientific and academic tool. As it grew, a strong anti- commercial culture grew with it. Cultural articularism,
*
regionalism, social expectations, work hours, political laws, transborder data and privacy laws.
Personnel. There are acute shortages of skilled consultants in
Nigeria.
* Costs and tariffs.
*
Regulatory constraints and standardization issues.
Activity 14.2
Describe some of the problems which internet present to its users.
