Disk access is way slower than
memory access. Caching is a technique to improve the disk access time. Block cache is a caching technique which
reduces disk accesses time. Here a
portion of disk is bought to cache for reading and a modified blocks are first
changed in cache but reflected in the disk at one go. On the other hand with write through caching
each modified block is written to cache and at the same time it is written to
the disk. Write- through caching
requires more disk I/O so they can have a negative effect on the performance.
When you use the word "address", I assume you are referring to an external address, in which case the answer is NAT (network address translation). Essentially, network address translation converts LAN IP addresses (local IP addresses) to WAN IP addresses (external IP addresses). So for instance: everyone in my home accesses the internet under our network's external IP address. Inside our network, we have local IP addresses, which allow for packets to be routed to our individual machines wirelessly. So let's say my IP address on the LAN is 192.168.1.4, and I want to access brianly.com. My router performs NAT by converting my local IP to an external one which can be used for accessing the web. Then when data comes back to the network from brainly's server, my router once again performs NAT to convert between my external IP to my local IP, so that my router knows where the data needs to be routed to on the LAN.

Answer:
subnet mask
Explanation:
A subnetwork or subnet mask is a logical subdivision of an IP network.
To find out your subnet mask, the simlest way around it is to is to run a simple command line in windows.
Simply press the Windows key and “R” at the same time to open the command prompt and type “cmd” followed by “enter.” This will allow you to see your subnet mask.
In IPv4, the subnet mask 255.255. 255.0 is 32 bits and consists of four 8-bit octets. The address: 10.10. 10.0 subnet mask 255.255.255.0 this simply indicated that the subnet mask consists of a range of IP addresses from 10.10.10.0 - 10.10.10.255.
Subnet masks (IPv4) are often involved in identifying the range of IP addresses that make up a subnet, it can also be described as a group of IP addresses on the same network.
