The Network Defines the Client

• Network maturity and bandwidth satisfies

demand

• Software development delivers the opportunities

• Established platforms offer best integration

potential

The NC defined...

• The NC is not a product, it is a spectrum of client devices

• NCs will differ in capability from consumer devices

• NCs will be used to access corporate information

• Intranet and Extranet growth will feed NC adoption in early stages

• The next generation client needs to be designed for intranet/extranet implementation

What is a Network Computer?

• Apple, IBM, Netscape, Oracle and Sun are introducing a Reference Profile for the Network Computer: the NC&trade

• This Reference Profile is intended to provide a common denominator of popular and widely used features and functions across a broad range of scaleable network computing devices, including personal computers

In practice what is a NC?

• One of the simplest example of Client-

Server network based application

• Powerful low cost RISC CPU and RAM

• Disk or diskless peripheral device

• LAN card for the comminucation I/O

• Monitor, Keyboard, Mouse and Audio

Output

In practice a particular evolution

of the classical X-Terminals• But with local CPU running applications

capability: – HTML Browser– Java Developer Kit and Java class libraries– Java interpreter– Java Virtual Machine– X-Windows – Windows NT Operating System (Windd, etc)– Security for the Intranet and Extranet

Cost-To-Use analysis is key

• IDG research utilises Cost-To-Use model• Established model measures business

computing costs• IDG survey contacted 125 IT managers in

France, Germany, UK and US• All businesses had networked PCs and X-

terminals (Intranet NC)• Cost-To-Use model reveals significant

savings when deploying X-terminals

Survey finds Intranet NC attractive

• NC has lower acquisition cost• Offers reduced costs for software and for

software maintenance and distribution• Offers reduced administration, support,

training and backup costs• Costs less to upgrade and maintain• Provides universal access to applications

and information together with Internet integration

Cost-To-Use reveals savings

• All line items yield a cost saving for the Intranet NC over the networked PC

• Most significant savings in hardware upgrades and applications development staff

• Five year costs of Intranet NC show 44% savings compared to networked PC ($39,114 vs $69,686)

Upgrades impact productivity

• Hardware and software upgrades extend the user down time

• Loss of productivity due to scheduled upgrades for intranet NC 25% of networked PC costs

• Loss of productivity due to unscheduled down time for intranet NC 36% of networked PC costs

Network offers choice

• Rise in network development offers choice to IT managers for occupational fit

• NCs provide the ideal client characteristics: simple, standard access without the cost and support expenses

• NCs promise is low-cost, low-administration, highly secure, enterprise access client desktops

• Intranet NCs deliver the NCs promise

HP and NCD (not tested yet)

• We don’t know anything yet about HP NC

• For the NCD are available both HTML Browser and Java Virtual Machine (the XWindows S/W is already well known in the LNF)

• The already installed NCD (Explora series only) are upgradable to become Network Station with a simple S/W reinstallation on the X Server

• HMX model has best performance of Explora-pro
