Practice Reading: Multiple Choice, Single Answer ID: #50241 Packet
Instructions ›
Read the text and answer the multiple-choice question by selecting the correct response. Only one response is correct.
Internet data, whether in the form of a Web page, a downloaded file or an e-mail message, travels over a system known as a packet-switching network. In this system, the data in a message or file is broken up into packages about 1,500 bytes long. Each of these packages gets a wrapper that includes information on the sender's address, the receiver's address, the package's place in the entire message, and how the receiving computer can be sure that the package arrived intact. Each data package, called a packet, is then sent off to its destination via the best available route -- a route that might be taken by all the other packets in the message or by none of the other packets in the message.

According to the text, which description below of the transmission process is NOT true?

Option 1: "The receiving computer can determine whether or not the package is intact all by itself."

Explanation: The text states that the package includes information on how the receiving computer can verify that the package arrived intact. This implies that the receiving computer does not determine this on its own but relies on the information provided in the package.

Option 2: "In a packet-switching network, the data cannot be transmitted without being cut into packages."

Explanation: The text mentions that data is broken into packages for transmission, but it does not state that data cannot be transmitted in any other form. Therefore, this statement is too absolute and does not accurately reflect the text.

Option 3: "Apart from the data, a package also carries with it some other information."

Explanation: The text explicitly states that each package includes information such as the sender's address, receiver's address, and the package's place in the message. This confirms that the statement is true, as it accurately reflects the content of the text.

Option 4: "There are different routes for the transmission of data in a packet-switching network."

Explanation: The text indicates that packets can take the best available route, which may differ from the routes taken by other packets. This means the statement is true, as it aligns with the information provided in the text.
