28 Questions
What is the main purpose of a network?
To share resources
Which of the following is NOT considered a resource in a network?
A monitor
What does networking involve?
Designing, implementing, and working with networks
How are devices connected in a network?
Using special hardware and software
What is network topology?
The physical layout of a network
What is a key advantage of using a network switch over a hub?
Conserves network bandwidth
In a 10-Mbps network with 10 nodes communicating through a hub, what happens to the bandwidth each node can get?
Each node may only get a portion of the 10 Mbps
How does a switch differ from a hub in terms of bandwidth allocation to connected devices?
Switch provides full bandwidth to each device
What is the impact of multiple nodes communicating on a hub compared to a switch?
Nodes on a hub share the bandwidth, affecting speed
Which device configuration allows each node to communicate at its full bandwidth capacity in a network?
Switch
What is the purpose of a Wide Area Network (WAN)?
To connect LANs and other types of networks together
What is a Metropolitan Area Network (MAN) defined as?
A network that connects users with computer resources in a larger region than LANs
What is the main disadvantage of networking related to costs?
Hardware and Software Management Costs
Which type of network covers a broad area and uses routers and public communications links?
Wide Area Network (WAN)
What is a fundamental characteristic of Local Area Networks (LANs)?
They cover small geographic areas like homes or offices
Why are Wide Area Networks (WANs) necessary in networking?
To allow communication between users and computers in different locations
What happens to the entire network if the central device in a star network goes down?
It goes down as well.
Why are star topologies more expensive to install compared to bus networks?
Because they require more hubs.
In a ring topology network, what happens if one entity is removed from the ring?
It goes down completely.
What is a characteristic of the physical ring topology systems that led to their decline?
They were complex and expensive.
What makes mesh topology the most complex in terms of physical design?
The need for multiple connections.
Why do some types of Ethernet and ARCNet use a physical star topology?
Because it simplifies data transmission.
What is the main advantage of using a router over a bridge?
Routers can determine the best path for sending data.
Why are routers typically slower than bridges?
Routers need to analyze every packet.
Where are routers commonly located?
At gateways where networks connect
What is a key function of a network switch as compared to a network hub?
Switches contain more 'intelligence.'
How do routers differ from bridges in terms of connectivity?
Routers can connect LANs to WANs.
Why are routers more expensive compared to bridges?
Routers need to analyze every packet.
