The Ultimate Quiz On Computer Networking! Trivia

An IP address (or IPV4 number) is a set of four numbers, each ranging from 0 to 255. This is because an IP address is a 32-bit number, divided into four octets, and each octet can have a value from 0 to 255. This range allows for a total of 4,294,967,296 unique IP addresses to be assigned.

Bandwidth is the measure of the amount of data that can be transmitted over a network connection in a given amount of time. It is commonly expressed in bits per second (bps). Therefore, bandwidth is the value that can be expressed in bits per second. Time To Live, File Size, and Last Update Time are not typically measured in bits per second.

The acronym NOS stands for Network Operating System. This refers to a specialized software that manages and controls network resources, allowing multiple computers to communicate and share data. NOS provides services such as file sharing, printer sharing, and security protocols, enabling efficient network management and operation.

The default SMTP (outgoing) server port number is 25. SMTP stands for Simple Mail Transfer Protocol and it is used for sending emails. Port 25 is the standard port used by SMTP servers for outgoing mail.

IMAP (Internet Message Access Protocol) is a mail protocol that allows a computer to work with mail directly on the server. Unlike POP3 (Post Office Protocol version 3), which downloads emails to the device and removes them from the server, IMAP keeps the emails on the server and allows users to access and manage them from multiple devices. This makes it convenient for users who access their emails from different devices as they can synchronize their mailbox and have consistent access to their emails. SMTP (Simple Mail Transfer Protocol) is used for sending emails, while HTTP (Hypertext Transfer Protocol) is used for web browsing.

A Denial of Service (DoS) attack is a malicious attempt to render a networked system unusable. This is typically achieved by overwhelming the targeted system with a flood of illegitimate requests or by exploiting vulnerabilities to exhaust its resources. The goal of a DoS attack is to disrupt the normal functioning of the system, making it unable to respond to legitimate users or perform its intended functions.

The correct answer is Address Resolution Protocol. ARP is a protocol used to map an IP address to a physical or MAC address on a local network. It allows devices to communicate with each other by resolving the IP address of a destination device to its corresponding MAC address. This is necessary because devices on a network communicate at the MAC address level, and ARP helps in identifying the MAC address of a device based on its IP address.

Intranets use the TCP/IP protocol as a basic protocol. TCP/IP is a suite of communication protocols that enables the transfer of data over networks. It is widely used in both local area networks (LANs) and wide area networks (WANs). TCP/IP provides reliable and efficient data transmission by breaking data into packets and ensuring their delivery to the intended destination. It also includes protocols like IP (Internet Protocol) for addressing and routing, and TCP (Transmission Control Protocol) for establishing and maintaining connections between devices. Overall, TCP/IP is the fundamental protocol used in intranets for seamless communication and data transfer.

Fast Ethernet is 10 times faster than standard Ethernet. This means that the data transfer rate of Fast Ethernet is 10 times higher than that of standard Ethernet. This increase in speed allows for faster and more efficient communication and data transmission between devices on a network.

Wireless networks use radio waves to send information. Radio waves are electromagnetic waves that have long wavelengths and low frequencies. They are able to carry signals over long distances and can easily penetrate through walls and other obstacles. This makes radio waves the ideal technology for wireless communication, allowing devices to connect to the internet and transmit data without the need for physical cables.

Manufacturers of network adapters burn the MAC address into their products in order to uniquely identify them. The MAC address, also known as the Media Access Control address, is a unique identifier assigned to network interfaces. It is a hardware address that is permanently assigned to the network adapter during manufacturing. This address is used by the network devices to communicate with each other on a local network. Unlike IP addresses, which can change, the MAC address remains constant and helps in ensuring the proper delivery of data packets within a network.

CAT5 twisted pair cable contains four wire pairs.

The default POP3 (incoming) port number is 110. This is the port number that is commonly used for receiving email messages from a mail server using the POP3 protocol.

PPP stands for Point-to-Point Protocol. This protocol is used to establish a direct connection between two network nodes, typically over a serial interface. It is commonly used in dial-up connections and is responsible for establishing and maintaining the link between the sender and receiver. The other options, Peer-to-Point Protocol and Peer-to-Peer Protocol, do not accurately represent the correct acronym for PPP.

Proxy servers provide network firewall, connection sharing, and caching technology for networks. A proxy server acts as an intermediary between clients and other servers. It can filter and block certain types of network traffic, providing a firewall to protect the network. It can also share internet connections among multiple devices, allowing them to access the internet through a single connection. Additionally, proxy servers can cache frequently accessed web content, reducing bandwidth usage and improving network performance. Therefore, proxy servers are the correct answer for this question.
