CMW Chapter Nine Kep Terms, computing in the modern world
A _ covers a large geographic area, such as a city, country, or the world, using a communications channel that combines many types of media.
Wide Area Network (WAN)
The _ is...
a. the design of computers, devices, and media in a network
b. categorized as either client/server or peer to peer
A _ server is a dedicated server that stores and manages files.
A _ is a legal document that permits users to install software on multiple computers, usually at a volume discount.
A _ is a network that connects computers and devices in a limited geographical area, such as a home, school computer laboratory, or office building.
local area network (LAN)
Each computer or device on a local area network, called a _, often shares resources such as printers, large hard disks, and programs.
A _ is a high-speed network that connects networks in an area such as a city or town and handles the bulk of comminications activity across that region.
metropolitan area network (MAN)
A _ server is a dedicate server that manages printers and print jobs.
A _ server is a dedicated server that stores and prvides access to a database.
A _ server is a dedicated server that manages network traffic activity.
-a cable forms a closed loop
-all computers and devices are arranged along the loop
-if one node fails, the other computers are also affected
-all of the computers and devices (nodes) on the network are connected to a single wire
-if one node fails, the network goes down
-all of the computers and devices (nodes) on the network are connected to a central device.
-the central device that provies a common connection point for nodes on the network is called the _.
-if one node fails, only that node is affected. the rest of the network is okay.
-most schools and buisnesses use this type of network.
_ is the most popular LAN technology because it is relatively inexpensive and easy to install and maintain.
_ has been adopted as a network standard for Internet communications.
TIP/IP (Transmission control protocol/internet protocol)
When a computer send data over the Internet, the daata is divided into small pieces, or _.
Each _ computer in a house can...
-share a single high-speed Internet connection
-access files and programs on other computers in the house
-share peripherals such as a printer, scanner, external hard disk, or DVD drive.
A _ is a LAn that uses no phyisical wires.
WLAN (wireless local area network)
A _ is a an adapter card, PC card, or flash card that enables a computer or device to access a network.
NIC (network interface card)
-the ammount of data, instructions, and information that can travel over a communications channel
-determined by the amount of traffic or usage at one given time
_ is the time it takes a signal to travle fomr one location to another on a network.
The _ is the world's largest WAN (wide area network)
On a network a _...
-controls access to the hardware, software, and other resources on the network.
-provides a centralized storasge area for programs, data, and information.
_ technology uses short-range radio waves to transmit data between two devices.
_ is a newer networlk standard developed by IEEE that specifies how woreless devices communicate over air in a wide area.
