2. Background-Early Computers Early terminals “I think there is a world market for maybe five computers.” T. Watson, Chariman of IBM, in 1943

3. 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

4. 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

5. Client-Server History 1970’s – Dumb Computer Terminals 1980’s – Personal Computers 1990’s – Networked Computers (Fat Clients) 1996 – Thin Clients

6. JackPC 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.client/serverclientdata processingserver 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.boot imageweb browserX11Citrix ICARDP A thin client is a network computer without a hard disk drive, whereas a fat client includes a disk drive.network 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.server

7. JackPC 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: boot image control Lower IT admin costs Easier to secure Lower hardware costs Worthless to thieves

8. JackPC Disadvantages of Thin Clients Single point of failure Limited memory at each workstation Server/back end support expensive Not as versatile

9. JackPC Advantages of Fat (thick) clients Less network bandwidth Fewer server requirements Better multimedia performance More flexibility

10. 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

11. JackPC What is JackPC? “Desktop in the jack” OR “computer in the wall” Is a thin client computer which operates in a Server Based Computing environment

18. JackPC Network Network 10/100 Fast Ethernet, twisted pair (RJ-45) with Auto-negotiate TCP/IP with DNS and DHCP Point-to-Point Protocol (PPP) SNMP support allows remote configuration of device settings, reporting of device configuration and attached devices Compliant with standards: IEEE 802.3-LAN & 802.3U-LAN

19. 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.networking hardwareEthernetCategory 5data cablingcables 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.

22. JackPC Software highlights 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 Optimize network utilization by mapping your network layout Into the Xcalibur Farm Benefit from SSL encryption, traffic compression, port number control, bandwidth control and more Automate software distribution, image upgrades and recovery by configuring the software installation- services at the Farm/Site/Ip Scope level For security and asset management reasons, use device- authentication to prevent unauthorized device usage Securely authenticate thin client Users in front of your Domain

23. JackPC Software Features Standard MMC snap-in administration tool Combines logical (Active-Directory-based) and physical (Xcalibur-Farm- based) management models Uses existing Active Directory Tree structure to perform management tasks Assigns management policies to devices in any Active Directory level Scalable by adding Xcalibur Front End-Servers to the Xcalibur Farm as needed Fault tolerant through Redundancy & Load Balancing Centralizes remote deployment of software to devices Centralizes configuration, upgrade and troubleshooting of devices Uses existing Active Directory permission delegation and inheritance model to assign management permissions. Uses an Independent Management Protocol that has built-in support for: SSL Encryption, Compression, Port Number Control, Bandwidth Control and more Optimizes enterprise network infrastructure by using Xcalibur Sites and Proxies for bandwidth optimization
