Lesson 4 Flashcards
The—— is basically a huge network that connects hundreds of thousands of smaller networks. Central to this arrangement is the client/server network.
Internet
A —- computer is a computer requesting data or services
client
A——-, or host computer, is a central computer supplying data or services requested of it.
server
The —- of the Internet is the backbone, the fastest part, which links to slower types of connections, such as those of ISPs.
foundation
——— provide each customer with a Point of Presence (POP) – a local access point to the Internet – a collection of modems and other equipment in a local area. The POP acts as a local gateway to the ISP’s network.
ISPs
The —- in turn connects to an Internet Exchange Point (IXP), a routing computer at a point on the Internet where several connections come together.
ISP
Each IXP has at least one computer, whose task is simply to direct Internet traffic from one IXP to the next. IXPs are connected by the ———- known collectively as the Internet backbone, high-speed, high-capacity transmission lines, usually fiber-optic lines, that use the newest communications technology to transmit data across the Internet.
equivalent of interstate highways
is a not-for-profit cooperative university/business education and research project that enables high-end users to quickly and reliably move huge amounts of data over high-speed networks.
Internet2
The key lies in the ———6, or set of rules, that computers must follow to transmit data electronically.
protocol
The protocol that enables all computers to use data transmitted on the Internet is called——-.
Transmission Control Protocol/Internet Protocol, or TCP/IP
The. determines how the sending device indicates that it has finished sending a message and how the receiving device indicates that it has received the message.
TCP/IP
An ——— uniquely identifies every computer and device connected to the Internet.
Internet Protocol (IP) address
Each time you connect to your Internet access provider, it assigns your computer a new IP address, called a———, for your online session.
dynamic IP address
A dynamic IP address changes each time you connect to the Internet. A —— is the same every time a person logs on to the Internet.
static IP address
Although no one really “owns” the Internet, several global and US organizations establish standards for it. Everyone on the net adheres to standards overseen by the international Board of Trustees of ———- was established to regulate human-friendly Internet domain names.
