What is the function of the data link layer?
exchanging of data between interconnected devices
Blank are standard methods or formats for communication between networked devices?
Protocols
What are standardized procedures for communicating between network devices?
These are called protocols - a standard set of rules for common communications across networks.
Which tcp-ip layer is responsible for exchanging segments between devices on a tcp-ip network?
The Transport layer
TCP and IP are examples of?
TCP and IP are examples of protocols - a common set of agreed upon rules for communications between networks and devices.
How protocols work?
Protocols are set of standards that help programmers/designers/administrators to have common set of standards for Computing & Network Devices.
Differences between hub and web?
A hub is a layer 1 network device (hardware), and the 'web' is a software concept implemented by different protocols and multiple devices.
Which term is used to describe the process of establishing a connection between any two Bluetooth devices?
Authentication is the term for establishing a connection between any two Bluetooth devices.
Why are data link protocols required?
Protocols are a commonly agreed-upon set of rules for common communication between devices. At the data link layer they have to agree on the rules of how the frame is constructed, otherwise there would be no correct way to deliver frames to the intended systems.
Suppose your organization's pstn and voip systems are integrated and that your voip system adheres to architecture specified in h.323?
Answer B H.323 gateway (A device that provides translation between network devices running H.323 signaling protocols and devices running other types of signaling protocols (for example, ss7 on the PSTN). Page 548
Distinguish between Synchronous and Asynchronous protocols?
The terms "synchronous" and "asynchronous" refer to the two different styles of exchanging information in a digital system between two ports or devices. In both styles, messages need to be organized in order to ensure that they are properly handled. Synchronous messages typically use some sort of external clock to match data exchange, while asynchronous messages simply move at their own individual rates of speed, relying on established systems of rules to ensure proper routing. All computer systems employ both methods of communication and there are a number of different protocols for each.
What are expansion buses?
An expansion bus is made up of electronic pathways which move information between the code of a computer system, including the CPU and RAM, and peripheral devices. It is a collection of wires and protocols that allows for the expansion of a computer
