MOHANTESH.The topic given to us isTELEPHONE DIRECTORY.

WE have done veryhard work on this project givento us. We have searched manybooks and websites to completethe given task and under the


4/41

guideline of my respectedteacher I completed my work.

INTRODUCTION

A telephone directory is a

collection of telephonenumbers and associatedcustomer details. However,unlike a standardtelephonedirectory, where the user uses

customer's details (such asname and address) in order toretrieve the telephone numberof that person or business, a

telephone directory allowsusers to search by a telephone

service number in order toretrieve the customer detailsfor that service.

Telephone directories are usedby law enforcement and other

emergency services in order todetermine the origin of anyrequest for assistance, howeverthese systems include both

publicly accessible (listed) and

private (unlisted) services. Assuch, these directories arerestricted to internal use only.

Publicly accessible reversetelephone directories may be

provided as part of the standarddirectory services from thetelecommunications carrier insome countries. In other

countries these directories areoften created byphone

phreakers by collecting theinformation available via thepublicly accessible directoriesand then providing a searchfunction which allows users tosearch by the telephone service

details.

Advantages and disadvantagesof using telephone directory

Advantages:-A telephone directoryusually is used so that people

can find all of the contactnumber in their area, usually intheir city or their locality. Theidea is that anybody can easily

access that information and useit any time, whenever they reallywant. Now this is good and badat the same time, because you

can only find the numbers thatyou need in your locality. If you

are looking for a business that isout of town, you cant find it inthe local telephone directory.

Disadvantages:-

The main problem of info

gathering methods such as freetelephone directory is that suchmethods are often abused, whichcauses people to be botheredabout their privacy and leakage

of personal information toundependable companies. Withthe introduction of free rtelephone directory you mustgive even more consideration towatching over your delicate info

from identity theft.
