Protocol Used to Report Error Messages
The protocol used to report error messages is ICMP (Internet Control Message Protocol). ICMP is a network layer protocol that is responsible for reporting errors and providing diagnostic information in IP networks. It is an integral part of the Internet Protocol Suite and is used by network devices to communicate error messages and control information.
ICMP provides the following functions:
- Error Reporting: ICMP is primarily used to report errors that occur during the transmission of IP packets. When a network device encounters an error, such as a destination unreachable or a time exceeded, it will generate an ICMP message to inform the sender of the error.
- Network Testing and Troubleshooting: ICMP also includes tools that can be used for network testing and troubleshooting purposes. For example, the "ping" command uses ICMP echo request and echo reply messages to test the reachability and round-trip time of a network host.
- Path MTU Discovery: ICMP is used for Path Maximum Transmission Unit (PMTU) discovery. It allows network devices to determine the maximum size of a packet that can be transmitted without fragmentation along a given path.
- Router Discovery: ICMP Router Discovery messages are used by hosts to discover neighboring routers on an IP network.
In conclusion, ICMP is the protocol used to report error messages in IP networks. It plays a crucial role in error reporting, network testing, troubleshooting, and other network management tasks.

Statement (i): An address with all bits 1 is interpreted as all networks or all hosts.

• This statement is true.


• An address with all bits 1 is known as the broadcast address.


• When this address is used, it is interpreted as a request to send data to all networks or all hosts within a network.


• For example, in a network with an IP address of 192.168.1.0 and a subnet mask of 255.255.255.0, the broadcast address would be 192.168.1.255.

Statement (ii): The class A network 128.0.0.0 is defined as the loopback network.

• This statement is false.


• The loopback network is defined as 127.0.0.0/8, not 128.0.0.0.


• The loopback address 127.0.0.1 is used to test network connectivity on a local machine.


• It is commonly used for troubleshooting and is not assigned to any physical network interface.

Therefore, the correct answer is (i) only.

Inter Process Communication (IPC)
Inter Process Communication (IPC) refers to the mechanisms and techniques used by different processes running on a computer system to communicate and share data with each other. It allows processes to exchange information, synchronize their activities, and coordinate their actions.
Methods of Inter Process Communication
There are several methods of IPC that can be used for communication between processes. These methods include:
1. Mails:
- Processes can communicate with each other by sending messages through a mailbox or a message queue.
- Messages can be exchanged asynchronously, allowing processes to communicate even if they are not running at the same time.
- This method is commonly used in message-oriented middleware systems.
2. Messages:
- Processes can communicate by sending messages directly to each other.
- Messages can be sent using various protocols, such as TCP/IP or UDP/IP.
- This method allows for both synchronous and asynchronous communication between processes.
3. System Calls:
- Processes can use system calls provided by the operating system to communicate with each other.
- System calls such as pipe, shared memory, and sockets can be used for IPC.
- This method allows for efficient and reliable communication between processes.
4. Traps:
- Processes can use software interrupts or traps to communicate with the operating system or other processes.
- Traps can be used to request services from the operating system or to notify other processes about events.
- This method is commonly used in event-driven systems.
In conclusion, inter process communication can be done through various methods such as mails, messages, system calls, and traps. The choice of IPC method depends on the requirements of the system and the nature of the communication between processes.
