Thin Clients

A thin client is the term used when a dummy pc is used, a network PC without HDD to act as a terminal. This is because the data processing mostly occurs on the server itself. It is also a term used when most of the software of the network pc you are using is on the server itself rather than the pc. Thin clients require constant server communication to be keep running the way it should.

Advantages and Disadvantages

  • Easy to deploy requiring no extra or specialised software installations
  • Need to validate with the server after data capture
  • If the server goes down the collection of the data will go down
  • Any workstation can be used on the network to do the same thing
  • Reduced security threat

Thick Clients

A thick client is the term used when a network pc that does most of its own processing for on the client itself rather than the server like a thin client. It also refers to the fact software is on the PC itself rather than a server. If the applications you are using require multimedia components or are bandwidth intensive a thick client will be much more effective.

Advantages and Disadvantages

  • Thick clients are much more expensive and require more IT work in the future
  • Data verified by client immediately
  • Only requires some communication with server
  • Reduced server demands
  • Increased security issues

Revision Questions

1. which of the following apply to thick client network?

most of processing done on device instead of server
this is true
better for multiple devices than peer to peer
easier to manage
less reliant on server than thin client
thin client almost all processing on server
well protected from malware
less reliant on central device so less susceptible and easily backed up and protected

2. True/False: A thick client runs everything through the server, your machine only processes the inputs from the keyboard and mouse.

TRUE
Naa
False
Alright, we get it, you're smart. Shut up.

3. What is a Thick (Rich) Client server?

A client that does no processing.
Just cos it's rich doesn't mean it can't do work.
A client that does all its own processing.
Alright, we get it, you're smart. Shut up.
A slightly overweight server.
...??

4. Thick Client is when all of the processing takes place on the client machine

True
False

5. The processing in a thin-client network takes place on the the central server.

True
False

6. What are the advantages of a thick client?

Better data and program processing
Can work offline
Less security vulnerability
It is more cost effective

7. Which is an advantage of a thin client?

much more expensive and require more IT work in the future
You big dumb dumb
Easy to deploy requiring no extra or specialised software installations
Yeah alright u got it, stop braggin about it.
If the server goes down the collection of the data will go down
Thats a disadvantage. What is wrong with you?
None of the above
bruh

8. Which of the following are true for thin clients?

Applications are stored on the server rather than the client
True, thin clients do not have applications installed on them; processes occur on the server.
Devices are operable without a connection to the network / server
False, the opposite is true.
Thin clients require a connection to the network
True, as otherwise they are inoperable
Thin clients always have lower specifications than a thick client
False - a thin client could have greater specifications than a thick client, though it does not necessarily need it.

9. What is a dumb terminal and when is it used?

Used with thin clients.
Used with thick clients
A terminal that doesn't work for it's intended function
A PC lacking in certain pieces of hardware, but can still form an input and output

10. In what instances would a thin client be useful to a user.

When using a device with very low processing power.
When trying to run a video game directly from the device.
To act as a highly secure dummy, between other clients and the server,
To process tasks while moving around offline.
