Q3-3 How Does a Typical Web Server Move Data on a Network? Flashcards
What is three-tier architecture in web servers?
Three-tier architecture is an arrangement of user computers and servers into three tiers:
User tier – consists of devices like computers and smartphones.
Server tier – contains computers running web servers and application programs.
Database tier – consists of computers running a database management system (DBMS) that stores and retrieves data.
What is the function of the server tier in a three-tier architecture?
The server tier consists of web servers that process user requests, run applications, and manage the HTTP traffic by sending and receiving web pages to and from clients.
What is a web server?
A web server is a software program that runs on a server-tier computer, managing HTTP traffic, sending and receiving web pages, and processing requests from clients.
How does a login server function in three-tier architecture?
A login server receives user credentials and sends them to the DBMS to check against stored data.
If the credentials match, the login server grants access and returns the requested web page.
What is a web farm, and why is it important?
A web farm is a facility with multiple web server computers working together to distribute work and reduce customer delays.
It ensures the performance of large-scale websites by balancing the load across many servers.
How does a DBMS function in three-tier architecture?
The DBMS in the database tier processes requests to retrieve or store data in a database.
It works with the server tier to ensure that the correct data is delivered to the web server and subsequently to the user.
