If data is delivered corrupted does it become useless?
Generally yes, but there are exceptions such as voice over IP and live streaming
What are the different types of networks?
Personal Area Network (PAN), Local Area Network (LAN), Wireless Local Area Network (WLAN), Campus Area Network (CAN), Metropolis Area Network (MAN), Wide Area Network (WAN)
What is a Metropolitan Area Network (MAN)?
A computer network that interconnects users with computer resources in a city. It's larger than a campus area network, but smaller that a wide area network.
What are two minimum aspects of a network?
1) Physical (Wires, Cables, Wireless media)
2) Logical connections (Data transporting across the physical media
What is a Personal Area Network (PAN)?
A small network used for personal use to share data from one device to another. Examples Smart Phone to Laptop, Smart watch to Smart Phone.
What is a Wide Area Network (WAN)?
A computer network that extends over a large geographical distance, typically multiple cities and countries. Examples: The internet and Google offices in different states.
What is a network simplified?
Simplified: Two connected computers sharing resources with one another.
What is a Local Area Network (LAN)?
A computer network within small geographical area, such as a single room or group of buildings. Examples: Home Networks, Small office Network
What is Peer-to-Peer?
1) All computers on this network are peers, there's no dedicated servers and there's no centralized control over shared resources. 2) Any device can share its resources as it pleases. 3) Any computer can act as a client or server. 4) Easy to setup, and common in homes and small business
Computers in a network must be capable of determining the...
Origin and destination of a piece of information, i.e. it's IP and Mac Address.
What is a Wireless Local Area Network (WLAN)?
A LAN that's fully dependent on wireless connectivity. Most home networks are WLANs. Also referred as SOHO device i.e. Xbox, laptop
What is Client-Server?
The network is composed of C's and S's, S's provide resources and C's receive resources. 2) S's provide centralized control over network resources (files, printers, etc.) 3) Centralized user accounts, security, and access controls to simplify network administration. 4) More difficult to setup and requires an IT admin. 5) More common in medium to large businesses.
What are communication protocols?
Computers in a network must use the same procedures for sending and receiving data
What is a Campus Area Network (CAN)?
A computer network of multiple interconnected LANs in a limited geographical area, such as a corporate business, park, government agency, or university campus.
