Answer 1

Hint: In order to go through the question the very first thing we should about is data. Observation yields quantifiable units of information, which we call data. A datum (singular of data) is a single value of a single variable in a more technical context. Data is a collection of values for qualitative or quantitative variables about one or more people or items.

Complete step by step solution:
Before getting the point answer of the given query let us first know about different types of switching.
Packet switching: Packet switching is a form of sorting data that is transmitted over a digital network into packets in telecommunications. A header and a payload make up a packet. Networking hardware uses the header data to guide the packet to its destination, where the payload is extracted and used by application software.
Circuit switching: Circuit switching is a telecommunications network implementation technique in which two network nodes establish a dedicated communications channel (circuit) across the network before communicating. The circuit guarantees the channel's maximum bandwidth and remains connected during the contact session. The circuit works as if the nodes were physically bound in the same way that an electrical circuit does.
Telephone switching: A telephone exchange, switch, or central office is a form of telecommunications device found in the public switched telephone network (PSTN) and large businesses. It establishes telephone calls between subscribers by interconnecting telephone subscriber lines or virtual circuits of digital networks.
Telex switching: The telex network, similar to a telephone network, was a customer-to-customer switched network of teleprinters that used telegraph-grade connecting circuits for two-way text-based communications. Telex was a common method of sending written messages electronically between businesses.
Packet-switched networks are those that route relatively small units of data called packets across a network based on the destination address found in each packet. By breaking down communication into packets, the same data path can be used by multiple users on the network. Connectionless communication is the term for this form of communication between sender and receiver (rather than dedicated). Packet switching is used for the majority of Internet traffic, and the Internet is essentially a connectionless network.
So, from the above information we can say that the correct option is: A. Packet switching

Note: A computer on the internet or a local network is identified by its IP address, which is a unique address. IP addresses are the identifiers that enable information to be transmitted between devices on a network: they contain location information and allow devices to communicate with one another.
