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.

false
Explanation:
The term 'computationally expensive' means that a given mathematical function, code or an algorithm has high computational complexity. In addition, the mathematical function or algorithm will require several steps and procedures to be completed. Based on this, the statement made in this question is not true.
An alien from planet Tao has descended onto Earth. The Internet is a massive network of networks, a networking infrastructure. It connects millions of computers together globally, forming a network in which any computer can communicate with any other computer as long as they are both connected to the Internet.
Explanation:
- A packet is the unit of data that is routed between an origin and a destination on the Internet or any other packet-switched network.
- Network packets are small amounts of data passed over TCP/IP networks.
- Latency measures the time it takes between your actions and the response between your computer, the internet, and everything in between.
- An IP address is a label which is used to identify one or more devices on a computer network. It is comparable to a postal address.
- The Domain Name System (DNS) is vital to the Internet, providing a mechanism for resolving host names into Internet Protocol addresses. Insecure underlying protocols and lack of authentication and integrity checking of the information within the DNS threaten the proper functionality of the DNS.
- Transmission Control Protocol is a standard that defines how to establish and maintain a network conversation through which application programs can exchange data. TCP works with the Internet Protocol which defines how computers send packets of data to each other.
