What are design issues?
1. A design issue often represents
a challenging problem through the operational requirements and capabilities of a robotic system
. A design issue is usually a very important item of the design process that will lead to specific design solutions.

What are design issues of physical layer and network layer?
The physical layer is basically concerned with transmitting raw bits over a communication channel. Mainly the design issues here deal with
electrical, mechanical, timing interfaces, and the physical transmission medium
, which lies below the physical layer.
What is layered architecture and explain its design issues?
The main aim of the layered architecture is
to divide the design into small pieces
. Each lower layer adds its services to the higher layer to provide a full set of services to manage communications and run the applications. It provides modularity and clear interfaces, i.e., provides interaction between subsystems.
What are network layers?
The network layer is
the third level (Layer 3) of the
Open Systems Interconnection Model (OSI Model) and the layer that provides data routing paths for network communication. … Logical connection setup, data forwarding, routing and delivery error reporting are the network layer’s primary responsibilities.
What happens in transport layer?
Layer 4 of the OSI Model: Transport Layer
provides transparent transfer of data between end users
, providing reliable data transfer services to the upper layers. The transport layer controls the reliability of a given link through flow control, segmentation and desegmentation, and error control.

What are the issues in designing a distributed system?
- the lack of global knowledge.
- naming.
- scalability.
- compatibility.
- process synchronization (requires global knowledge)
- resource management (requires global knowledge)
- security.
- fault tolerance, error recovery.
What is the physical layer?
Physical Layer is
responsible for the communication of the unstructured raw data streams over a physical medium
. Physical Layer maintains the data rate (how many bits a sender can send per second). It performs Synchronization of bits. It helps in Transmission Medium decision (direction of data transfer).
What are the responsibilities of network layer?
Main responsibility of Network layer is
to carry the data packets from the source to the destination without changing or using it
. If the packets are too large for delivery, they are fragmented i.e., broken down into smaller packets.
What is the design of a network layer?
The network layer or layer 3 of the OSI (Open Systems Interconnection) model is
concerned delivery of data packets from the source to the destination across multiple hops or links
. It is the lowest layer that is concerned with end − to − end transmission.
What are the two main types of network models?
Networks are divided into two types,
a LAN (Local Area Network) or a WAN (Wide Area Network)
, which are generic terms referring to two important basic types of networks.
Why network is divided into layers?
To ease network engineering, the whole networking concept is divided into multiple layers.
Each layer is involved in some particular task and is independent of all other layers
. But as a whole, almost all networking tasks depend on all of these layers.
What is PDU in CAN protocol?
In telecommunications, a protocol data unit (PDU) is
a single unit of information transmitted among peer entities of a computer network
. … A layer lower in the Internet protocol suite, at the Internet layer, the PDU is called a packet, irrespective of its payload type.
