What are the advantages and disadvantages of network data model?
Network data model is just like a normal database model. In network model the data is seen as related to each other by links. Or we can say the relation between the data is represented by links.
Are the distinct units of the data that are exchanged between nodes on a network?
Data packets Source: Page 10 of Network+ Guide to Networks by Tamara Dean (5th Edition)
For which three reasons was a packet-switched connectionless data communications technology used when developing the internet?
- It can rapidly adapt to the loss of data transmission facilities. - It efficiently utilizes the network infrastructure to transfer data. - It Data packet can travel multiple paths through the network simultaneously.
Which network uses the same infrastructure to carry voice data and video?
A Converged network is used to carry all three.
How would you describe a network?
A network is a collection of interconnected entities that can communicate and share resources with one another. This can include computers, devices, or individuals linked through various communication channels, such as cables, wireless signals, or social connections. Networks can be structured in different ways, like local area networks (LANs) or the broader internet, facilitating collaboration, data exchange, and access to shared services. Ultimately, networks enhance the efficiency and effectiveness of interactions within the connected system.
What is the term used to describe a discrete unit of data that is sent from one node to another over the network?
Packet
What is the purpose of the OSI model?
An OSI, or Open Systems Interconnect, model is a standard industry model that is used to describe how software data moves through a network from one computer to another. It has seven layers that are application, presentation, session, transport, network, data link, and physical.
Can a network facilitate backup of data from one computer to another?
Yes.
What changes data from one network to a format another can understand?
Gateway!
Which term is often used to describe data service units?
Megabytes (MB) or Gigabytes (GB) are often used to describe data service units, representing the amount of data that can be transferred over a network or stored on a device.
What does a router do when it receives a data packet from another network segment?
nothing.
Can a network switch be considered a router?
No. By definition a router forwards data from one network to another. For example it would route data from you local LAN to Internet, or from one LAN to another. Further they typically use header information in the data packets to determine the best path to send the data through.
What is the term used to describe converting one data type into another data typein C programming?
Cast.
What are the Set of formal rules used in describing how to transmit data across a network?
Those are the Standards - an agreed upon set of protocols (rules) to describe network communication.
What is wormhole attack?
A network that tunnel information to another network, that is it get the data from one network replicate it into another network through tunnel that particular network may confused due to this action. At that time hacker may easily enter and do misuse inside the network Prof.L.Thanga Mariappan sos
Why does your computer say data is already in use by another user?
The data might be in use by some other process on your computer or on a network.
How can you describe the Ethernet Carrier Sense function enables network nodes to determine if the network media is in use?
It examines the cable to see if there is any activity on it before sending out data.
