Background-Early Computers

Early terminals

“I think there is a world market for
maybe five computers.”

T. Watson, Chariman of IBM, in 1943
Background-Personal Computer

These units have their own
processing power and storage

“There is no reason anyone would
want a computer in their home”
Ken Olsen, Digital
Equipment Corp.,
now part of Compaq

Personal Computer Proliferation

So many specialized devices required
to run a network that the typical
business PC was referred to as a “fat
client”

“640K ought to be enough for
anyone”

Bill Gates, Microsoft CEO, 1981
Client-Server History
1970’s – Dumb Computer Terminals
 1980’s – Personal Computers
 1990’s – Networked Computers (Fat
Clients)
 1996 – Thin Clients

Thin Client vs. Fat Client




In client/server applications, a thin client is designed to
be especially small so that the bulk of the data
processing occurs on the server.
The word "thin" refers to the small boot image which
such clients typically require - perhaps no more than
required to connect to a network and start up a
dedicated web browser or "Remote Desktop" connection
such as X11, Citrix ICA or Microsoft RDP.
A thin client is a network computer without a hard disk
drive, whereas a fat client includes a disk drive.
A fat client is a client that performs the bulk of any data
processing operations itself, and relies on the server it is
associated with primarily for data storage.

 Advantages

of Thin Clients
boot image control is much simpler when only
thin clients are used - typically a single boot
image can accommodate a very wide range of
user needs, and be managed centrally, resulting
in:
 Lower IT admin costs
 Easier to secure
 Lower hardware costs
 Worthless to thieves
JackPC

Disadvantages of Thin Clients

Single point of failure

Limited memory at each workstation

Server/back end support expensive

Not as versatile
JackPC
 Advantages
of Fat (thick) clients

Less network bandwidth

Fewer server requirements

Better multimedia performance

More flexibility
JackPC

Disadvantages of Thick Clients

Less secure-more prone to theft

Need to add programs/software to each
machine individually

Expensive initial cost of investment

“Desktop in the jack”
OR “computer in the
wall”

What peripheral devices can be supported by Jack-PC?
Most peripheral devices will work:
a. Most keyboards (including wireless keyboards)
b. Most mice (including wireless mice)
c. All USB printers
d. Most USB storage devices including USB keys and cameras
e. Approved wireless USB devices
f. Approved USB smart-card readers
g. Most USB touch-screen controllers
h. Approved USB to PS/2 converters
i. Approved USB to serial ports
Does Jack PC support USB storage devices?
Yes. Most storage devices are supported.
Note: for security reasons by default anything other than keyboard
and mouse is blocked. Specific user or device policy is needed to
enable this support
Can I use wireless keyboard / mouse with Jack-PC?
Yes. Most models are supported
Does Jack-PC support wireless LAN? Yes. Certain USB wireless
devices are supported using specific plug-ins.

JackPC Network

Power over Ethernet

a solution where electrical current is run to networking
hardware over the Ethernet Category 5 or higher data
cabling. No extra AC power cord is needed at the product
location, minimizing the amount of cables needed and/or
the hassle of installing extra outlets.




integrates power and data onto once single cabling
infrastructure, eliminating the need to have AC power
available at all locations.
Power and Data is integrated onto the same cable,
supporting category 5/5e up to 100 meters.
During power failures, PoE ensures continuous operation of
remotely connected devices
widely adopted in the market, saving up to 50% of overall
installation costs by eliminating the need to install separate
electrical wiring and power outlets.

Integrate Chip PC thin clients Into the Active Directory view
Use the existing Active Directory tree structure to manage thin
clients
Real-time management OR Policy-based management? You can
have them both!
Assign Xcalibur policies to devices And Users in any Active
Directory level
Leverage Windows security and rights delegation to assign thin
client management permissions
