Answer:
Auto-negotiation protocol is the modern technology in the networking. This protocol allow the ethernet equipment for automate different instillation steps. This type of protocol use by interconnecting various electronic devices for negotiating the speed of the link.
Advantages:
- The auto negotiation protocol features used to maximize the throughput of data link layer.
- This protocol are basically useful in the local area network (LAN), with multiple capability of connections.
- The auto negotiation protocol extremely useful in twisted pair which are based on ethernet.
Disadvantages:
- This type of protocol are not fixed data links and not used as backbone of the networks.
- Duplex mismatch occur then, it cause significant loss in the packets.
Answer:
The Session layer (Layer 5)
Explanation:
The OSI (Open Systems Interconnection) seven-layer model is a reference model that explains how devices (or applications) communicate over the network. The model consists basically of seven different layers which are;
i. Layer 1 or the physical layer
ii. Layer 2 or the data-link layer
iii. Layer 3 or the network layer
iv. Layer 4 or the transport layer
v. Layer 5 or the Session layer
vi. Layer 6 or the presentation layer
vii. Layer 7 or the application layer.
Out of the seven layers, the session layer (layer 5) keeps track of a system's connections to send the right response to the right computer by setting up, coordinating and managing these connections. It controls, establishes and maintains the connection between multiple computers or applications on a computer.
Answer:
Explanation:
The basic concept of virtual reality is that they are a pair of lenses in a headset that allows you to visualize a virtual 3D world and become immersed within it. To do the exercises correctly Anna would need to follow the following basic steps.
Put the virtual glasses over her eyes, complete the exercises in the virtual world, take the virtual glasses off
The headset/glasses need to fit comfortably on her eyes and around her head so that she can clearly see the image on the lenses and so that the headset/glasses do not fall off while she is completing her exercises. Once she is done with her exercises Anna can simply take off her virtual glasses and put them away.
With digital technology, the storage method has changed and today it is much easier to handle and transport movies to theatres than in the past. Servers, hard disks and video tapes are being used to store movies and digital projectors are being used to screen them.
Answer:
The loading symbol means that it's trying to resolve somthing did you leave any applications on or did your computer warn you that an update was coming that could cause the software to malfunction.
