Explanation:
A Local Area Network (LAN) is a network that connects computers and devices within a limited area, such as a home, office, or school. It allows connected devices to share information, resources, and peripheral equipment. Here is a detailed explanation of why option 'C' is the correct answer:
Sharing Information:
One of the main purposes of a LAN is to enable devices to share information. When computers are connected to a LAN, they can easily transfer files, documents, and data between each other. This allows for better collaboration and efficient communication within the network.
Sharing Peripheral Equipment:
Another benefit of a LAN is the ability to share peripheral equipment. Peripheral devices such as printers, scanners, and storage devices can be connected to a central server or a designated computer on the network. All other devices on the LAN can then access and use these peripherals, eliminating the need for individual devices for each computer.
Running Faster:
While being connected to a LAN does not directly make a computer run faster, it can enhance network performance. LANs typically have higher data transfer speeds compared to external internet connections. This means that data transfers between devices within the LAN can happen at faster rates, improving overall network performance.
Sending Email:
Being connected to a LAN enables computers to send and receive emails. LANs can be set up with email servers that handle incoming and outgoing email traffic. This allows users on the network to send emails to each other and to external email addresses.
Going Online:
While being connected to a LAN provides access to shared resources and devices within the network, it does not necessarily provide direct access to the internet. Additional network configurations, such as a router or gateway, are required to connect the LAN to the internet. Therefore, option 'B' is not correct in this case.
In conclusion, a computer connected to a LAN can share information and peripheral equipment, making option 'C' the correct answer.

Diya Choudhary answered |
HTTPS (Hypertext Transfer Protocol Secure) is the correct answer.
- The Hypertext Transfer Protocol (HTTP) is a protocol used for communication between a client and a server over a network. However, it is not secure because the data exchanged between the client and server is not encrypted, making it vulnerable to interception and tampering.
- FTP (File Transfer Protocol) is a protocol used for transferring files between a client and a server. Similar to HTTP, FTP is not secure and does not provide encryption for the data being transferred.
- TCP/IP (Transmission Control Protocol/Internet Protocol) is a set of protocols that govern the transmission of data over the Internet. While TCP/IP is essential for communication over the Internet, it does not specifically address security.
- SMTP (Simple Mail Transfer Protocol) is a protocol used for sending emails between servers. Like HTTP and FTP, SMTP does not provide encryption for the email contents.
HTTPS, on the other hand, is a combination of HTTP and SSL/TLS (Secure Sockets Layer/Transport Layer Security) protocols that adds an extra layer of security to HTTP. Here's how it works:
1. Encryption: HTTPS uses SSL/TLS to encrypt the data transmitted between the client and the server. Encryption ensures that the data is scrambled and cannot be easily deciphered if intercepted by unauthorized parties.
2. Authentication: SSL/TLS also provides authentication, which ensures that the client is communicating with the intended server and not an impostor. This is achieved through the use of digital certificates issued by trusted Certificate Authorities.
3. Data Integrity: HTTPS ensures data integrity by using hash functions that verify the integrity of the transmitted data. If any tampering is detected, the connection is terminated.
4. Port: HTTPS typically uses port 443 instead of the default HTTP port 80. This allows the server to distinguish between HTTP and HTTPS requests.
In summary, HTTPS is used for secure communication over the Internet by encrypting data, providing authentication, and ensuring data integrity. It is commonly used for secure transactions, such as online banking, e-commerce, and sensitive data transfers.

Rhea Reddy answered |
An HTTP request consists of three parts.
The first part is the message description in the start line. Also called the request line, this line begins with a method token, followed by the Request-URI and the protocol version ending with CRLF.
Also known as header fields, the next part attributes in a block of headers. The request-header area allows the client to pass some additional information regarding the request and about the client itself to the server. Such fields act as request modifiers.
Finally, we have an optional part called the message body with the data contained in it.
Hence, 3 Is the correct answer.

Download is the correct answer.
Explanation:
When we want to transfer information from one source to our computer, the process is known as downloading. It involves the retrieval of data from a remote server or another computer and saving it onto our local device.
Process of Downloading:
1. Request: We initiate the download process by sending a request to the server or source from which we want to obtain the data.
2. Transfer: The server then transfers the requested data to our computer over a network connection. This data can include various types of files such as documents, images, videos, software, etc.
3. Saving: Once the data is received, our computer stores it in a specified location, usually in a folder or directory of our choice. This allows us to access and use the downloaded files whenever needed.
Comparison with Other Options:
- Upload: Uploading refers to sending data or files from our computer to a remote server or another computer. It is the opposite of downloading.
- Transfer: While transfer can be a general term for moving data between devices, in the context of the given question, it specifically refers to the act of downloading information from one source to our computer.
- De-link: De-linking does not involve the process of transferring or retrieving data. It refers to removing a link or connection between two entities, such as unlinking a webpage from a website.
Hence, the correct term for taking information from one source and bringing it to our computer is downloading.

Network Communication and Application Standards
Network communication between applications is established and maintained according to certain standards that define the protocols and rules for data transmission. One of the most important standards is the Transmission Control Protocol (TCP).
TCP - Transmission Control Protocol
TCP is a widely used transport layer protocol that provides reliable communication over an IP network. It ensures that data packets are delivered in the correct order and without errors. TCP establishes a connection-oriented communication between applications, meaning that a connection is established before data is transmitted.
Establishing a Connection
When two applications want to communicate with each other over a network, TCP follows a three-way handshake process to establish a connection:
1. SYN: The client sends a SYN (synchronize) packet to the server, indicating its desire to establish a connection.
2. SYN-ACK: The server responds with a SYN-ACK packet, acknowledging the request and indicating its willingness to establish a connection.
3. ACK: The client sends an ACK (acknowledge) packet back to the server, confirming the connection establishment.
Maintaining the Connection
Once the connection is established, TCP ensures the reliable transmission of data by implementing various mechanisms:
1. Segmentation: TCP breaks the data into smaller segments and assigns a sequence number to each segment. This allows the receiver to reassemble the segments in the correct order.
2. Acknowledgment: After receiving each segment, the receiver sends an acknowledgment (ACK) back to the sender. If the sender does not receive an ACK within a certain time, it retransmits the segment.
3. Flow control: TCP monitors the receiver's buffer capacity and adjusts the transmission rate accordingly to prevent overflow or underflow of data.
4. Congestion control: TCP detects network congestion by monitoring the round-trip time of packets and the number of unacknowledged packets. It reduces the transmission rate to alleviate congestion and prevent network collapse.
Conclusion
In summary, the establishment and maintenance of network communication between applications follow the TCP standard. TCP ensures reliable data transmission by establishing a connection through a three-way handshake process and implementing mechanisms such as segmentation, acknowledgment, flow control, and congestion control.

Nikita Singh answered |
As a message is divided into a number of packets, each packet can, if necessary, be sent by a different route across the internet. Packets can arrive in a different order than the order they were sent in. The Internet Protocol just delivers them. So, routing which is the process of moving data from one network to another by forwarding packets via gateways, is the correct answer.
