(1) Local area netweoks

(2) wide area networks

(3) Internets

connects computers that reside in a single geographic location on the premises of the company that operates the LAN

can range from 2 to several hundred

single location

a network of networks

Connects WAN, LAN, & Internets

LANS

fewer than a dozen or so computers and printers

on these cables are light rays and they are reflected inside the glass core of the wire

can replace UTP cable

used for wired LAN connections

standard->ethernet

NICs support

conform to 802.3 specifications and allow for transmissions at a rate of 10,100,or 1000 mbhs (megabites per second)

wireless LAN connection

most current one

allows speeds at up to 600 mbps

another common wireless protocol

designed for transmitting data over short distances, replacing cables.

3 functions:

(1) provides you with a legitimate internet address

(2) serves as your gateway to the internt

(3) ISPs pay for the internet

commonly connected to an ISPs in 1 of 3 ways:

(1) special telephone line called a DSL line

(2) a cable TV line

(3) wireless-phone-like connection

a scheme of 5 protocol types arranged in layers

physical: protocol for applications

data link: protocols about data communications

Internet: protocols about data communications

Transport: protocols for data transmission within a network

Application: Protocols for data transmission within a network

used to move files over the internet

commonly used to maintain websites

collaborative management

requirement gaps

transition problems

employee resistance

break your traffic up into pieces and send each piece along its way

reliable internet transport

assignment is controlled by this public agency

must be unique

e-commerce applications use this

arrangement of user computers and servers into 3 categories:

(1) user

(2) server

(3) database

contains the URL of the web page to find when the user clicks the hyperlink

a variable used to provide properties about a tag

not all tags have attributes

as the elastic leasing of poled computer resources over the internet

used because most early diagrams used a cloud symbol

in-house hosting, delivered via web service standards, that can be configured dynamically

cloud is the future for most organizations

vendors provide hosted computers, an opearting system, and possible a DBMS

add their own application to the host

specifically how web browsers and other programs can determine that services offered by a PaaS program, how to send & receive data to such a program, how to query and process PaaS database and so on.

simplifying program tasks
