With a client-based network, one fundamental problem is that:
a) the clients each must store all the data
b) the server does not have any data storage capability
c) the host or server must perform presentation logic, application logic, and data access logic at the same time
d) all data on the server must travel to the client for processing
e) the clients must perform the data storage logic

This client server model has several advantages and disadvantages which are important to mention and know when establishing if it is what we need or if it suits what we are looking for.

Disadvantages

It requires skill for a server to be repaired. For example, if a problem occurs on the network, someone with a large number of it is required to be able to repair it in its entirety in order to let the information and the proper functioning continue its flow.
Another problem is security, the fact that information channels are shared between servers and clients require that they go through validation processes, that is, security protocols that can have some type of open door allowing physical damage, threats or attacks to be generated. of malware.
This model represents an important limitation in terms of economic costs because these servers are high-level computers with specific hardware and software to enable our applications to function properly. Something important to note is that it is not only expensive to solve problems as mentioned before, but also has a high cost to replace components that are damaged.
