IPv4 has 32 bits and IPv6 has 128 bits.

• IPv4 addresses are in the format of xxx.xxx.xxx.xxx where each xxx is an 8-bit number.

• IPv6 addresses are in the format of xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx where each xxxx is a 16-bit number.

• IPv6 addresses allow for a much larger number of unique addresses than IPv4.

IPv6 is needed due to the exhaustion of IPv4 addresses and the need for more unique IP addresses.

• IPv6 provides a significantly larger address space compared to IPv4.

• It allows for the allocation of unique IP addresses to every device connected to the internet.

• IPv6 supports improved security features and better network performance.

• It enables the growth of Internet of Things (IoT) devices and services.

• Transitioning to IPv...read more

Anycast, unicast, and multicast are different ways of routing network traffic.

• Unicast is one-to-one communication between a sender and a receiver.

• Anycast is one-to-nearest communication where the sender sends a message to the nearest receiver.

• Multicast is one-to-many communication where the sender sends a message to a group of receivers.

• Anycast is used for load balancing and finding the nearest server.

• Unicast is used f...read more

Virtual memory is a memory management technique that allows a computer to use more memory than physically available.

• Virtual memory is created by using hard disk space as an extension of RAM.

• It allows running more programs than the physical memory can handle.

• The size of virtual memory is typically larger than the size of main memory.

• Virtual memory is divided into pages, which are swapped in and out of main memory as nee...read more

• Queues: FIFO structure, ideal for managing tasks and scheduling.

• Trees: Hierarchical structure, used ...read more

The difference is that 'int arr[5]' creates an array on the stack, while 'malloc(5*sizeof(int))' allocates memory on the heap.

• int arr[5] creates an array of 5 integers on the stack, which is a fixed-size memory allocation.

• malloc(5*sizeof(int)) dynamically allocates memory on the heap, allowing for variable-size memory allocation.

• The memory allocated with malloc must be explicitly freed with free() to avoid memory leaks
