Answer:
The correct answer to the following question will be "Encapsulation".
Explanation:
The wrapping of the data into a single unit or the method by which a header is applied to the data inherited from the above layer is termed as Encapsulation.
While relating to networking, encapsulation would be the method of storing and converting data through one protocol into another, so that the data can proceed over a network. A TCP/IP package contained under an ATM system, for example, is indeed a kind of encapsulation.
Therefore, Encapsulation is the right answer.
Answer:
1. Database
2. Tree
<u>Database</u>
An organized collection of data, that is stored form different computer system is called Database.
<u>Tree Topology</u>
A type of network in which multiple computers are connected in a tree like structure. This type of network topology is used to organize data in database.
<u>Explanation</u>
In banks database servers are used to organize and store large volumes of financial data.
<em>To organize such type of data with the help increasing number of employs on database, tree topology is used to connect all computers of that bank on the network,</em>
Answer:
the Telephone
Explanation:
Before the invention of electromagnetic telephones, mechanical acoustic devices existed for transmitting speech and music over a greater distance greater than that of normal direct speech. The earliest mechanical telephones were based on sound transmission through pipes or other physical media.The acoustic tin can telephone, or "lovers' phone", has been known for centuries. It connects two diaphragms with a taut string or wire, which transmits sound by mechanical vibrations from one to the other along the wire (and not by a modulated electric current). The classic example is the children's toy made by connecting the bottoms of two paper cups, metal cans, or plastic bottles with tautly held string.Some of the earliest known experiments were conducted by the British physicist and polymath Robert Hooke from 1664 to 1685. An acoustic string phone made in 1667 is attributed to him.For a few years in the late 1800s, acoustic telephones were marketed commercially as a competitor to the electrical telephone. When the Bell telephone patents expired and many new telephone manufacturers began competing, acoustic telephone makers quickly went out of business. Their maximum range was very limited. An example of one such company was the Pulsion Telephone Supply Company created by Lemuel Mellett in Massachusetts, which designed its version in 1888 and deployed it on railroad right-of-ways.Additionally, speaking tubes have long been common, especially within buildings and aboard ships, and they are still in use today. The telephone emerged from the making and successive improvements of the electrical telegraph. In 1804, Spanish polymath and scientist Francisco Salva Campillo constructed an electrochemical telegraph.The first working telegraph was built by the English inventor Francis Ronalds in 1816 and used static electricity. An electromagnetic telegraph was created by Baron Schilling in 1832. Carl Friedrich Gauss and Wilhelm Weber built another electromagnetic telegraph in 1833 in Göttingen.At the University of Gottingen, the two have been working together in the field of magnetism. They built the first telegraph to connect the observatory and the Institute of physics, which was able to send eight words per minute.
The correct answer is a group of personal computers located in the same general area and connected by a common cable.
