A router is needed to connect two computers in different networks or to share internet connection.
When two computers are in different networks, a router is needed to connect them.
A router can also be used to share internet connection between multiple devices.

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...
A /24 address can have 256 clients. Network address is the first IP and broadcast address is the last IP.

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...
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...

Contact dictionary can be implemented using hash table for fast lookups with O(1) time complexity.
Use a hash table to store contacts with keys as names and values as contact information.
Example: { 'John Doe': '555-1234', 'Jane Smith': '555-5678' }
Time complexity for searching, inserting, and deleting contacts is O(1) with a hash table.
