Internet Basics MCQs Set 13

Among the services available on the World Wide Web are:

(i) Encryption: Encryption is a service that ensures secure communication and protects data privacy on the web. It involves encoding information in such a way that it can only be decoded or decrypted by authorized parties. Encryption is commonly used for securing online transactions, protecting sensitive data, and maintaining confidentiality.

(ii) HTTP: HTTP (Hypertext Transfer Protocol) is a protocol that enables the transfer of information and data on the web. It defines how web browsers and web servers communicate with each other. HTTP is the foundation of web browsing and is responsible for retrieving web pages, sending data between client and server, and handling various types of web requests.

(iii) HTML: HTML (Hypertext Markup Language) is the standard markup language used for creating web pages and displaying content on the World Wide Web. It provides the structure and formatting for web documents, allowing the inclusion of text, images, links, multimedia elements, and more. Web browsers interpret HTML code to render web pages to users.

(iv) Firewalls: While firewalls are not a service provided directly by the World Wide Web, they play a crucial role in network security, including web-related activities. Firewalls are security mechanisms that monitor and control incoming and outgoing network traffic. They help protect networks and systems from unauthorized access, malicious activities, and potential threats, including those originating from the web. Firewalls often regulate web traffic by allowing or blocking specific types of connections, ports, or protocols.

In the destination email address [email protected], the portion "yyyy.zzzz.tttt" after the "@" symbol represents the domain name of the destination. The domain name is a unique identifier that specifies the address or location of the email recipient's email server or hosting provider. It helps route the email to the appropriate server for delivery to the intended recipient.

Yes, EDIFACT (Electronic Data Interchange for Administration, Commerce, and Transport) is a widely used international standard for electronic data interchange (EDI). EDI is the structured transmission of business documents between computer systems in a standard format that allows for seamless exchange of information.

EDIFACT provides a set of rules and guidelines for formatting electronic business documents, such as purchase orders, invoices, shipping notices, and more. It defines the syntax and structure of the data elements, segments, and messages exchanged between trading partners.

EDIFACT is commonly used in various industries and sectors globally, facilitating efficient and standardized communication between businesses. It enables automated and seamless electronic transactions, reducing manual data entry, improving accuracy, and enhancing business process efficiency.

The World Wide Web (WWW) consists of web pages. Web pages are documents that are accessible over the internet and are typically written in HTML (Hypertext Markup Language). These pages can contain various types of content, including text, images, videos, and interactive elements. Users can navigate between web pages by clicking on hyperlinks or using search engines to find specific pages of interest.

In an email address, the "@" symbol separates the local part from the domain part.

The EDIFACT (Electronic Data Interchange for Administration, Commerce, and Transport) standard was developed by the United Nations Economic Commission for Europe (UNECE). UNECE is a regional commission of the United Nations that focuses on promoting economic cooperation and integration among its member countries. The development of the EDIFACT standard began in the 1980s with the goal of establishing a common format for electronic data interchange (EDI) in international trade and business transactions. UNECE continues to oversee and maintain the EDIFACT standard, ensuring its relevance and compatibility with evolving technologies and business needs.

Yes, when an email is sent, it is typically first stored in a mail spool or email queue on the mail server. The mail spool is a temporary storage location where incoming emails are held before being processed and delivered to the recipient's mailbox. The mail server processes the messages in the spool, performs necessary checks and actions (such as spam filtering, virus scanning, etc.), and then delivers the emails to the respective recipient's mailbox or forwards them to other mail servers if necessary. The spool helps manage the flow of email messages and ensures their orderly delivery.

The ANSI X.12 standard, also known as ASC X12, was developed by the Accredited Standards Committee X12 (ASC X12). ASC X12 is a committee accredited by the American National Standards Institute (ANSI) responsible for developing and maintaining electronic data interchange (EDI) standards for various industries in the United States. ANSI X.12 defines the syntax, structure, and content for exchanging business transactions electronically. It covers a wide range of industries, including healthcare, retail, transportation, finance, and more. The ASC X12 committee continues to oversee and update the ANSI X.12 standard to ensure its relevance and compatibility with evolving business requirements and technologies.

Yes, when an email is received, it is typically stored in the recipient's mailbox. The mailbox is a storage location provided by the email service or server where incoming emails are stored until the recipient accesses them. The mailbox holds the received emails, along with any folders or labels the recipient has set up for organizing their emails. The recipient can access and manage their emails by using an email client application, such as Microsoft Outlook or Apple Mail, or through a web-based email interface (webmail) provided by the email service provider. The mailbox acts as a repository for received emails, allowing the recipient to read, reply, forward, or delete them as desired.

Among the given options, the following are true in B2B e-Commerce:

(i) Co-operating businesses should give an EDI standard to be used: In B2B e-Commerce, when businesses engage in electronic data interchange (EDI), they should agree upon and adhere to a specific EDI standard to ensure compatibility and seamless communication between their systems.

(ii) Programs must be developed to translate EDI forms to a form accepted by application programs: EDI forms may use a specific format or syntax that needs to be translated or converted into a format that can be processed and understood by the application programs used by the receiving business. Programs or software components are often developed to facilitate this translation process.

(iii) The method of transmitting/receiving data should be mutually agreed: In B2B e-Commerce, businesses need to agree on the method or protocol for transmitting and receiving data. This could involve choosing a specific communication protocol, such as AS2 (Applicability Statement 2), FTP (File Transfer Protocol), or others, based on mutual agreement and compatibility between the trading partners.

(iv) It is not essential to use the internet: While the internet is a common and widely used medium for B2B e-Commerce, it is not essential to use the internet exclusively. B2B transactions can be facilitated through other means, such as private networks, VANs (Value-Added Networks), or direct connections, depending on the specific requirements and agreements between the businesses involved.
