Yes , this had been made possible by the technology called Desktop Virtualization & device called THIN CLIENT, This technology facilitates us to use multiple desktops from 1 single CPU . Where each user can enjoy their own individual computer applications, just like a personal computer.
Suppose if you have 1 CPU with core i3 ( 1st gen) processor , 4 GB Ram , 500 GB Hard drive , 1GB Graphics Card , then you can easily run minimum 10 desktops .By purchasing these extra peripherals which is required to run 10 desktop is – 10 keyboards , 10 mouse , 10 monitors and 10 thin client .
How many maximum desktops can we run from 1 CPU using thin clients ?
It totally depends upon the power of your CPU , starting from minimum 5 desktops to 100 desktop you can use depending upon the configuration of your CPU.
What are the advantages & disadvantages of Thin Clients / ncomputing ?
Advantages of using thin clients are following :
- Huge money saving -Obviously, if you are not going to purchase the CPU for each desktops , it will reduce the installation cost up to 70% . Because for each desktops you only need a keyboard, mouse, monitor, and a thin client.
- Less maintenance is required – Since there is only one CPU which manages all workstations , Hence we need to install or troubleshoot operating system or application software in only one CPU , similarly there is less hardware parts hence it required less maintenance .
- More Power Saving : Desktop virtualization technique reduce your electricity bills , because it require only 1 single CPU.
- It Is best for school ,colleges, labs, small offices , cyber cafes etc
Disadvantages of using thin clients are following :
- Little bit slow operating speed – The operating speed & response time of each workstation is a bit slower .
- Low Graphics quality – Since graphics of 1 single graphics card or inbuilt graphics is divided between several work stations , hence the graphics quality is little bit poor.
- High definition movies , graphics rich games , and complex software applications like video editors and many more can not work properly with thin clients .
- Failure of CPU , turn off all work stations – Suppose if the cpu , restarts , hang or face any problem then all workstations will get effected with the problem.
Type of thin clients / ncomputing devices .
TYPE 1 – ETHERNET BASED THIN CLIENT / NCOMPUTING –
This is the most common and widely used thin client type, the network diagram of this type thin client is shown in figure.
For creating this type of network , we need 1 CPU , 1 network hub/switch , cat5 Lan cable , multiple RJ45 Connectors , multiple keyboards , multiple mouse, multiple monitors and multiple thin client / ncomputing devices.
Steps of installation of Ethernet based Thin Clients / Ncomputing.
Step 1– First Install the centralized software of the thin client / ncomputing on the CPU . which will allow you to control several permissions and functions of each work stations from the server.
Step 2 – Now insert a lan / Ethernet cable from the CPU to the any one port of the hub / switch.
Step 3 – Connect each individual thin clients / ncomputing device with other available ports in the hub/switch via lan / Ethernet cable.
Step 4 – Connect power supply to each thin clients with a separate power adapter provided with thin clients.
Step 5 – Now connect a separate , Monitor , keyboard , mouse to each thin client / ncomputing device. Which create multiple individual workstations , operated from a single CPU.
Advantages & Disadvantages of Ethernet based thin clients / ncomputing devices –
- Advantage – Additional workstations can be added latter on the network by using an extra thin client / ncomputing device. Maximum length of network can be extended up to 100 meters.
- Disadvantages – Slow operating & response speed , poor graphics quality , use separate individual power adapter for each thin client / ncomputing devices.
Type 2 – PCI CARD BASED THIN CLIENTS / NCOMPUTING DEVICES.
This type of thin clients is manufactured by companies like – Ncomputing , etc which comes in package ie – 1:3 thin client , 1:5 thin client,1:7 thin client , 1:11 thin clients and more . In this kind of thin clients , you can not add any extra work stations on the network than the mentioned number of workstations . here 1: 3 means you can only run maximum of 3 workstations from a single CPU , Similarly is the case with 1:5 , 1:7 , 1:11 etc.
Foe creating this type of network you need – 1 CPU , 1 thin client / ncomputing complete set ( which contains- 1 PCI Card and fixed number of access device ) , Fixed number of key board & mouse , No hub or any Ethernet device is required ,Here no external power adapter is required , each device get power from the CPU Via lan cable.
Steps of Installation of PCI CARD Based thin Clients / ncomputing devices –
Step 1 – Install the PCI Card in pci slot of your the mother board , your mother board must hav at least 1 PCI Slot , it does not get inserted in PCI Express slot .
Step 2 – Now install the Software of PCI card which comes with the package . This software is used to manage rest of workstations on the network.
Step 3 – Now connect each individual access device with one port of the PCI Card .
Step 4 – Now attach key board , mouse ,and monitor with each access device , which will create a separate workstation.
Advantages & Disadvantages of PCI Based thin clients.
Advantage – Operating speed, response time and graphics is comparatively better than Ethernet based thin client system.
Disadvantages – Can not add any extra workstation on the network and the maximum distance of LAN must be less than 10 meters.
