What is a group of computers that are connected with each other?
A network.
A set of networks that are connected with routers.
Internetwork
A private network whose access is generally restricted to authorized persons.
Intranetwork
Collection of networks under common administration that share a common routing strategy.
Autonomous system
A communications network that serves users within a confined geographical area.
LAN (local area network)
A network that spans a metropolitan area.
MAN (metropolitan area network)
A data communications network that serves users across a broad geographical area and often uses transmission devices provided by common carriers.
WAN (wide area network)
Network composed of different interconnected computer networks that cover an unlimited geographical area.
GAN (global area network)
These networks are used for a small number of systems, generally 2-10 users.
Peer-to-peer
These networks are designed for a relatively small number of people, with one server managing network access, security, file storage, email, web surfing, and all other needs. Generally for 10-50 users
Single-server network
Network containinig more than one server, often with each server serving a specialized purpose. Generally 50-250 users.
Multi-server network
A network that contains multiple servers, but different parts of the network may be located in different areas, such as different buildings. Generally 250-1000 users.
Multi-server high-speed backbone network.
A network containing hundreds of thousands of devices, most often geographically dispersed, but remaining under the management of one organization. Generally 1000+ users.
Enterprise network
What is used to uniquely identify (by use of binary or hexadecimal numbers) all nodes that need to participate in internetworking?
IP addressing
What is legacy internet addressing system with a limited number of addresses?
Internet protocol version 4 (IPv4)
___________ is when you create smaller “subnetworks” off of your network by manipulating the subnet mask.
Subnetting
This is a mechanism used to designate part of IP address as the network field and part of it as the host field.
Subnet mask
This internet addressing system is designed to replace IPv4, increasing the number of available IP addresses by over a billion time.
IPv6
What is normally the subnet mask in IPv6 addresses?
/64
How do you determine an IP range?
By combining the subnet range and the host range together.
What is classless inter-domain routing and when was it introduced?
A system that distributes addresses through the technique of variable length subnet masking (VLSM), and combines numerous small networks into larger networks for the purpose of tracking.
______ is used to effectively manage the waste of IP addresses on your network.
VLSM (variable length subnet masking)
Which AFI series covers communications-computer networking and information management?
33 series
_____ establishes AF policy for responsibly acquiring, planning and managing its information resources.
AFPD 33-1: Information Resources Management
