Problem Scenario:◦ Company “LTET” (Late to Embrace Technology) has
grown substantially in the last few years. ◦ The company manufactures, distributes, and sells
acoustic products. Its manufacturing plants are in China. Its assembly and distribution plants in addition to HQ and sales offices are in the US.
◦ Their current computing environment consists of a few computers scattered here and are not networked.
◦ They rely on paper and do everything manually, but now they are ready to embrace 21st century technologies.

A client/server environment includes:◦ Clients – typically single user PCs or workstations
with operating system and easy to use GUI interface
◦ Servers – provides shared services to clients(application server, database server, storage)
◦ Network – how it is all connected to each other

Used for communication between entities in different systems
◦ Entity – anything capable of sending or receiving(terminal, DBMS, user applications)
◦ System – physically distinct object that contains one or more entities (computers, terminals, remote sensors)
◦ Protocol is the language between the two

7 layer model that identifies protocols for communicating at different layers.
Example Protocols◦ Transmission Control Protocol / Internet Protocol
(TCP/IP)◦ IP – provides routing functionality between
multiple networks◦ TCP – ensures data arrives at the destination
application & the data arrives in the same order it was sent.

Simple Mail Transfer Protocol (SMTP)◦ Provides mechanism for transferring messages
among separate hosts
File Transfer Protocol (FTP)◦ Used to send files from one system to another
under user command
TELNET◦ Provides remote logon capability, which enables a
user at a terminal or PC to logon to a remote computer and function as if directly connected
