Computer Essentials - Section 5 Quiz

E-mail is a digital communication method that allows users to send and receive messages over the Internet. It is commonly used for exchanging written messages, documents, and files between individuals or groups. While it is possible to attach files to an email and download them, this is not the primary purpose of email. Similarly, making phone calls via the Internet is typically done through other applications like VoIP services, not email. Therefore, the correct answer is that email is used to send and receive messages via the Internet.

VoIP is a technology that enables making phone calls over the internet rather than traditional phone lines. It converts voice signals into digital data packets and transmits them over IP networks. This allows for cost-effective and efficient communication as it eliminates the need for separate infrastructure for voice and data. VoIP also offers additional features like call forwarding, voicemail, and video conferencing. Therefore, the correct answer is "Make phone calls."

Wi-fi is the correct answer because it is a wireless connection technology that allows devices to connect to the internet without the need for physical cables. It is commonly used in public places such as airports, cafes, and hotels to provide internet access to the public. Wi-fi networks are accessible to anyone within range and can be easily connected to using a smartphone, laptop, or other Wi-fi enabled devices.

The Internet is a global network of linked computer networks. It connects millions of devices worldwide, allowing them to communicate and share information. This vast network enables users to access a wide range of resources, such as websites, emails, and online services. It is not limited to a specific area or controlled by a single company, making it a truly global and decentralized network.

Transfer rate is the correct answer because it refers to the speed at which data can be transferred or moved from one computer to another. It measures the amount of data that can be transmitted per unit of time, usually expressed in bits per second (bps) or bytes per second (Bps). Transfer time, line capacity, and data level are not the appropriate terms to describe this concept.

An open wireless network refers to a network that is not password protected or encrypted, allowing anyone nearby to connect to it without any restrictions. This lack of security measures makes it accessible to anyone within range, increasing the risk of unauthorized access or data breaches.

The World Wide Web is a system of interlinked hypertext documents that are accessed through the Internet. It is a platform where users can access and navigate through various websites and webpages to gather information. Therefore, the correct answer is "access information via the Internet."

A secure wireless network is one that is password protected, meaning that only authorized users who have the correct password can access it. This ensures that only individuals who have been granted permission can connect to the network and prevents unauthorized access or potential security breaches.

An ISP stands for Internet Service Provider. It is a company or organization that provides internet access to customers. ISPs offer various types of internet connections, such as dial-up, DSL, cable, or fiber optic, and they also provide additional services like email accounts, web hosting, and virtual private networks (VPNs). ISPs play a crucial role in connecting individuals and businesses to the internet, allowing them to access websites, send and receive emails, and use other online services.

The correct answer is The Internet. A global network of linked computer networks refers to the Internet, which is a vast network that connects millions of computers and devices worldwide. It allows users to access and share information, communicate, and engage in various online activities. The Internet is not limited to a specific geographic area and is accessible to users across the globe.

The purpose of a network is to share data and access devices securely. Networks allow users to transfer and exchange information between devices, ensuring that data is shared in a secure and controlled manner. Additionally, networks enable users to access and utilize various devices connected to the network, such as printers, scanners, or storage devices, making it easier to collaborate and share resources within an organization or between individuals.

An intranet is a private company network that uses Internet technology. It is a network that is accessible only to the employees or members of the organization. It allows for the sharing of information, collaboration, and communication within the organization. Unlike the internet, which is accessible to the public, an intranet is restricted to authorized users, providing a secure and controlled environment for internal operations and data sharing.

A cable is a physical connection to the internet because it uses physical wires to transmit data signals. Unlike satellite, mobile phone, or Wi-Fi, which rely on wireless signals, a cable connection requires a physical cable to be plugged into a device, such as a computer or router, to access the internet. This physical connection ensures a more stable and reliable internet connection compared to wireless options, making cable a popular choice for home and office internet connections.

The correct answer is from a personal computer to a web server. Uploading files refers to the process of transferring data from a user's personal computer to a remote server on the internet. This can be done through various methods such as FTP, HTTP, or cloud storage services. In this scenario, the user is sending files from their personal computer to a web server, allowing the files to be accessed and stored remotely.

An ISP (Internet Service Provider) is a company that provides internet access to individuals and businesses. They offer various types of connections such as DSL, cable, or fiber optic, allowing users to connect to the internet and access websites, send emails, and perform other online activities. The other options listed (WWW, USB, EULA) are not service providers for connecting to the internet.
