Provides reliable connection oriented ransmission between two hosts. It guarantees delivery of packets between the hosts. 

The tag gets power through power from a reader antenna to the tag antenna. They are used for shorter range transmission.

(i) Network Access Layer - concerned with building packets. 
(ii) Internet Layer - describes how packets are to be delivered.
(iii) Transport Layer - ensure the proper transmission of data. 
(iv) Application Layer - application network processes. These processes include File Transfer Protocol (FTP), Hypertext Transfer Protocol, (HTTP), and Simple Mail Transfer Protocol (SMTP).

Open System Inter connection (OSI) model was found in the year 1934, over all basis that permits network protocols along with software and schemes to be developed based on Universal guide lines

It is a private network that uses Internet technology and the public tele communication system to securely share business's information with suppliers, vendors, partners, customers, or other businesses

(i) It Resolves IP addresses to MAC (Medium Access Control) addresses .
(ii) A MAC address is a hardware identification number that uniquely identifies each device on a network.

Network protocols have to do end-to-end process of secure on time and manage data or network communication.

Network protocols is that the usual procedures, rules, formal standards and policies comprised of formats which allocates communication between more than one device which connected to the network.

(i)  Internet Protocol (IP) is the principle of the communications protocol in the Internet protocols for layering on datagram across boundaries of other networks.
(ii)The main function is to allows Internet working and boost up the Internet.

i) HTTP - Hypertext Transfer Protocol
ii) HTTPS - Hypertext Transfer Protocol Secure
iii) FTP - File Transfer Protocol

Two types of RFID tags were Active RFID and Passive RFID systems.

(i) It provides mobility.
(ii) It provides connection to Internet.
(iii) Flexibility of LAN.
(iv) Ensures connectivity.
(v) Low cost, high benefits.

The common application of mobile networks is mobile phones, tablets, etc.. In the past, wireless communications largely used circuit switching to carry only voice over a network, but now currently both data and voice are being transmitted over both circuit via switched networks and packet switched networks.

Intranet is a private network within an enterprise to share company data and computing resources between the employees. It may consist of many interlinked local area networks.

(i)  Li-Fi is the short form of Light Fidelity.
(ii) Li-Fi is a wireless technology which uses light-emitting diodes (LEDs) for data transmission whereas Wi-Fi uses radio frequencies for data transmission.
