Chapter seven: Networking: Connecting Computer Devices
What is a computer network?
Networks is two or more computers connected via software and hardware so that
they can communicate with each other
Each device connected to a network is called a node
- Can be a computer, a peripheral, a game console, digital video recorder, or a
What are the benefits of networks?
To facilitate resource sharing
Allow you to share peripheral devices such as printers
Besides peripheral and Internet connections, does networking facilitate any
other types of resource sharing?
Can easily share files between networked computers without using portable storage
Can set sharing options in Windows or OS X
- Allows user to access files stored on any other computer on the network
- Public folders can be accessed by any computer on the network
Computers running different operating systems (Windows vs OS X) can
communicate on the same network
Are there disadvantages to setting up a network?
Networks involve purchase of additional equipment
Networks must me administered
Network administration involves
1. Installing new computers and devices
2. Monitoring the network to ensure it is performing efficiently
3. Updating and installing new software on the network
4. Configuring or setting up proper security for a network
Network architecture refers to the design of a network
- Are classified according to the way in which they are controlled and the
distance between their nodes
Describing Networks Based on Network Administration
What different types of control do I have over my network?
Can me managed in two ways
1. Locally: configuration and maintenance of the network must be performed
on each individual computer attached to the network (ex. Peer-to-peer) 2. Centrally: tasks can be performed from one computer and affect the other
computers on the network (ex. Client/server)
What is a peer-to-peer network?
Peer-to-peer (P2P) network each node connected to the network can
communicate directly with every other node on the network
What are client/server networks?
Client/server network contains two different types of computers
1. Client a computer on which users accomplish specific tasks and make
2. Sever the computer that provides information or resources to the client
computers on the network (ex. The Internet)
Are client/server networks used as home networks?
They can be configured for a home but P2P are used more often because they cost
less and are easier to maintain
Home network server is designed to store media, share media, and back up files on
computers connected to the network
- All computers connected to
