' Blac)berry is a personal communications de#ice de#eloped, distributed, and ser#iced

if you add a contact to your Contacts list$ he Blac)berry can be set up and operated wirelessly

without e#er being connected physically to a computer$/( currently offers Blac)Berry e.mail

contacts and calendar entries are 6pushed6 out to the Blac)Berry de#ice automatically, as

opposed to the user synchroni5ing the data by hand$ De#ice storage also enables the mobile user

to access all data offline in areas without wireless ser#ice$ 's soon as the user connects again,

the BES sends the latest data$

'n included feature in the newer models of the Blac)Berry is the ability for it to

trac) your current location through rilateration$!ne can #iew the online maps on the phone and

see current location denoted by a flashing dot$ &owe#er, accuracy of Blac)Berry trilateration is

less than that of %3S due to a number of factors, including cell tower bloc)age by large

buildings, mountains, or distance$

BES also pro#ides handhelds with C3G(3connecti#ity accessed through a

component called 6obile Data Ser#ice6 1DS$ his allows for custom application

de#elopment using data streams on Blac)Berry de#ices based on the Sun icrosystemsHa#a E

platform$

(n addition, BES pro#ides security, in the form of riple DESor, more recently, 'ESencryption

of all data 1both e.mail and DS traffic that tra#els between the Blac)Berry handheld and a

Blac)Berry Enterprise Ser#er$

ost pro#iders offer flat monthly pricing for unlimited data between Blac)Berry units and BES$

(n addition to recei#ing e.mail, organi5ations can ma)e intranetsor custom internal applications

with unmetered traffic$

4ith more recent #ersions of the Blac)Berry platform, the DS is no longer a

requirement for wireless data access$ Beginning with !S 9$8 or $0, Blac)Berry handhelds can

access the (nternet 1i$e$ C3G(3 access without an DS . pre#iously only e.mail and 4'3

access was possible without a BESGDS$ he BESGDS is still required for secure e.mail, data

access, and applications that require 4'3 from carriers that do not allow 4'3 access$

where the request for a gi#en transaction originates with the publisher or central ser#er$ (t is

with the recei#er or client$

called apublishGsubscribemodel$ ' client might 6subscribe6 to #arious information 6channels6$

4hene#er new content is a#ailable on one of those channels, the ser#er would push thatinformation out to the user$ Synchronous conferencing and instant messaging are typical

e*amples of push ser#ices$ Chat messages and filesare pushed to the user as soon as they are

recei#ed by the messaging ser#ice$ Both decentralisedpeer.to.peerprograms 1such as 4'SE

and centralised programs 1such as (/C orHabber allow pushing files, this means the sender

initiates the data transfer rather than the recipient$
