________ is a transport protocol developed by IBM but adopted by Microsoft for use in earlier versions of Windows and DOS. This protocol is commonly found in smaller networks due to the fact that it is a nonroutable protocol.
Explanation
NetBEUI is a transport protocol that was initially developed by IBM but later adopted by Microsoft for use in earlier versions of Windows and DOS. It is commonly found in smaller networks because it is a nonroutable protocol, meaning it cannot be used to communicate across different networks. NetBEUI is known for its simplicity and efficiency, making it suitable for smaller networks where routing capabilities are not required.Rate this question:

NetBEUI has a close friend, _______, with which it works closely when communicating with systems on the network. It is an application programming interface (API) that is used to make network calls to remote systems. When you install NetBEUI, it includes this protocol, and it relies on it for session management functionality. Also, it is nonroutable but may be installed with other routable protocols such as IPX/SPX or TCP/IP to allow it's traffic to travel across networks.
Explanation
NetBEUI has a close friend, NetBIOS, with which it works closely when communicating with systems on the network. NetBIOS is an application programming interface (API) that is used to make network calls to remote systems. When NetBEUI is installed, it includes the NetBIOS protocol and relies on it for session management functionality. NetBIOS is nonroutable but may be installed with other routable protocols such as IPX/SPX or TCP/IP to allow its traffic to travel across networks.Rate this question:
- 4.
This protocol has two communication modes, Session mode and Datagram mode.
Explanation
NetBIOS is a protocol that provides services for communication between computers on a local area network. It supports two communication modes, Session mode and Datagram mode. In Session mode, a connection is established between the communicating devices, allowing for reliable and ordered data transmission. Datagram mode, on the other hand, does not require a connection and allows for faster but less reliable transmission of data. NetBIOS is commonly used for file sharing, printer sharing, and other network services.Rate this question:
- 5.
This communication mode is used for connection-oriented communication in which NetBIOS would be responsible for establishing a session with the target system, monitoring the session to detect any errors in transmission, and then recovering from those errors by retransmitting any data that went missing or was corrupt.
Explanation
Session mode is the correct answer because it refers to the communication mode used for connection-oriented communication. In this mode, NetBIOS is responsible for establishing a session with the target system, monitoring the session for errors, and recovering from those errors by retransmitting any missing or corrupt data.Rate this question:
- 6.
This communication mode Is used for connectionless communication in which a session is not needed. It also is used for any broadcast by NetBIOS. It does not support error detection and correction services, which are therefore the responsibility of the application using NetBIOS.
Explanation
Datagram mode is a communication mode that is used for connectionless communication, meaning that a session is not required. It is also used for any broadcast by NetBIOS. In this mode, error detection and correction services are not supported, so the responsibility of ensuring data integrity falls on the application using NetBIOS. Therefore, the correct answer is Datagram mode.Rate this question:

______ is a routable protocol that was built by Novell and used in older version of Netware.
Explanation
IPX/SPX is a routable protocol developed by Novell and used in older versions of Netware. It stands for Internetwork Packet Exchange/Sequenced Packet Exchange. IPX/SPX was primarily used for communication between computers in a local area network (LAN). It provided reliable and efficient data transmission by breaking data into smaller packets and ensuring their sequential delivery. However, with the emergence of TCP/IP as the dominant networking protocol, IPX/SPX has become less common and has been largely replaced by TCP/IP in modern networks.Rate this question:
- 8.
This protocol is responsible for the routing of packets, it is also a connectionless, unreliable transport.
- A.
IPX
- B.
SPX
Correct Answer
A. IPXExplanation
IPX (Internetwork Packet Exchange) is the correct answer. IPX is a network layer protocol that is responsible for routing packets in a network. It is a connectionless and unreliable transport protocol, meaning it does not establish a connection before transmitting data and does not guarantee the delivery of packets. IPX was commonly used in Novell NetWare networks. SPX (Sequenced Packet Exchange) is a transport layer protocol that works in conjunction with IPX to provide reliable delivery of packets. However, the given statement does not mention SPX, making IPX the appropriate answer.Rate this question:

TCP is an example of a transport protocol responsible for:
- A.
Reliable delivery
- B.
Unreliable delivery
Correct Answer
A. Reliable deliveryExplanation
TCP (Transmission Control Protocol) is a transport protocol that ensures reliable delivery of data over a network. It achieves this by using various mechanisms such as acknowledgement, retransmission, and flow control. TCP guarantees that data packets are delivered in the correct order and without errors, making it suitable for applications that require accurate and error-free transmission, such as web browsing, email, and file transfer.Rate this question:

UDP is an example of a transport protocol responsible for:
- A.
Reliable delivery
- B.
Unreliable delivery
Correct Answer
B. Unreliable deliveryExplanation
UDP (User Datagram Protocol) is a transport protocol that provides unreliable delivery of data. Unlike TCP, UDP does not guarantee that the data will be delivered successfully or in the correct order. It is a connectionless protocol that does not establish a dedicated connection before sending data. UDP is commonly used for applications that prioritize speed and efficiency over reliability, such as streaming media, online gaming, and DNS. Since it does not have the overhead of error checking and retransmission, UDP can deliver data with lower latency, but it also means that data may be lost or arrive out of order.Rate this question:

- 20.
_____________ communication is a form of communication in which the sending system does not “introduce” itself—it just fires the data off. Also, the destination computer does not notify the source when the information is received. This type of communication can be unreliable because there is no notification to guarantee delivery. It can be faster than the other type of communication because the overhead of managing the session is not there, and after the information is sent, there is no second step to ensure proper receipt of information.
Correct Answer
ConnectionlessExplanation
Connectionless communication is a form of communication where the sending system does not identify itself and simply transmits the data without any acknowledgment from the destination computer. This type of communication can be unreliable as there is no guarantee of delivery. However, it can be faster than connection-oriented communication because there is no overhead of managing the session and no need for a second step to ensure proper receipt of information. Therefore, the correct answer is "Connectionless."Rate this question:
- 21.
This type of communication means data is sent without acknowledgment of receipt.
- A.
Unreliable
- B.
Connectionless
Correct Answer
A. UnreliableExplanation
This type of communication, known as unreliable, refers to the transmission of data without any acknowledgment of receipt. In this type of communication, there is no guarantee that the data will reach its intended destination or that it will be received correctly. It is called unreliable because there is a possibility of data loss or errors during transmission.Rate this question:
-
- 22.
This type of communication means that a session is not established before transmitting.
- A.
Unreliable
- B.
Connectionless
Correct Answer
B. ConnectionlessExplanation
Connectionless communication refers to a mode of communication where a session is not established before transmitting data. In this type of communication, each packet is treated independently and does not require a dedicated connection or acknowledgment from the receiver. This approach allows for faster transmission and reduced overhead, making it suitable for applications where reliability is not a primary concern, such as streaming media or real-time communication.Rate this question:

This protocol is a transport-layer protocol that is responsible for breaking the data into manageable packets and ensuring that the packets reach their destination. It is considered a connection-oriented protocol, which means that it relies on a session being first established. This is different from a connectionless communication, which just sends the data out and if it reaches the destination, great; if not, no big deal. With connection-oriented protocols, a session is established through introductions. (“Hi, I’m Glen Clarke. Nice to meet you, I am going to send you some data.”) Connection-oriented protocols will monitor that session to ensure that the packets have reached their destination.

This protocol is a standardized method of transferring files between two machines. It is a connection-oriented protocol, which means that the protocol verifies that packets successfully reach their destinations. This other, closely related protocol has the same purpose and function as the previous, except that it is not a connection-oriented protocol and does not verify that packets reach their destinations. By not verifying that data has been successfully transferred to its destination and therefore requiring less overhead to establish and maintain a connection, it is able to operate faster than the previous protocol. It has no authentication mechanism, whereas the previous protocol can require a username and password.
