Question

question 1 Differentiate between fat and thin clients. (3 points) State two advantages of using thin clients over fat clients. (2 points) question 2 Suppose that your uncle is a real estate agent and he decided to have a web-site to list his available real estate properties. And use a laptop computer to show clients these properties. What hardware is needed to have a web-site and client to browse the properties on that web-site? How many (n-tired) computers are needed for this system? List at least one advantage for this new system? question 3 Case Study: describe using ERD diagram how the university can manage Building, Classroom, Course, students, and Instructors, each of which is a table that is drawn indicating Primary Key, and Foreign key. Then explains how the university can add a new course without conflicting with others courses’ time and classroom. Notice: the relation between Course and Student is m-to-m because a Student may have more than one Course has more than one student. Draw the ED-D using crows-feet notation. Show the entities and relationships between entities (Building, Classroom, Course, student, Instructor). Indicate the PK primary key, and FK foreign key in each table)

Explanation / Answer

Think client has a lot of the logic and examines activity in the client. Hence they tend to be large, computer-intensive and transmitting less data.But in case of A thin client, he has minimal logic, which is just sufficient to display information in the desired format. Thick client involvs back to the two tier client-server. This menas that contains information that where you install the client software and who are authorized.In case of Thin Client, it is browser based.Hence he don't need to install any heavy stuffs and it's available across so many platforms.But Thick and thin client architecture is actually quite similar. In both cases,the client application running on a PC whose function is to send and receive data over the network. Thick and thin are the terms used to refer only hardware.

Thin client

Thick client

It is Easy to deploy because no need of specialized software installation

But it is expensive to deploy

More downtime

less downtime

Needs to validate with the server

Data verified by client

Here Reduced security threat

More security issues
