Computer network model will determine the
amount of charge needed to build its infrastructure. A
mistake in the determination of the network model in an
agency would be bad in the budget should be spent. In fact, in
the purchase of goods such as computers, software licenses
and other supporting infrastructure today is still relatively
expensive. Therefore, required an adjustment effort needs
with costs to be incurred by an institution to build a
computer networks. In this paper will discuss the comparison
of the three models that are cost effective computer networks
between LTSP (Linux Terminal Service Project), Userful and
N-Computing. This research was conducted by calculating
the costs that need to build the network and the effectiveness
of treatment in terms of the three models in use.

Computer Network Model
LTSP
Userful and
NComputing
From the research that has been done, from 4 kinds of
models that we use (regular LAN network, n-computing,
and userful LTSP), it can be concluded that:
1) The network model LTSP (Linux Terminal
Server Project), this network model requires more
skills in the configuration, but for technicians
often handle network configuration is not so
difficult. In the case of any procurement savings
model of this network because it does not require
a hard drive on the client computer, the network
model can also be run on a computer with the
specs are still low. Its performance in terms of
opening applications, the network model is also
not inferior to standard network model. 2) The computer network n-computing, network
model has weaknesses in its performance, as
the network model is sometimes experienced a
fair amount of time loading process, and
display on the client NComputing less
satisfactory. Substantial costs in procurement
but the cost of care and the cost of the
electricity expenditure, NComputing network
model more efficient. NComputing
configuration was not so complicated.
3) Model userful network, this network model
also save in terms of cost because the client
does not need the CPU itself but only requires
additional VGA on the server computer.
