What are two components of network architecture?
-Programmed services and protocols that move the messages across the network -Technologies that support network communications
Which layer of the OSI reference model permits the devices on the network to hold ongoing communications across the network?
network session layer Session Layer (Layer 5) The session layer permits two parties to hold ongoing communications called a session across a network.
What does business use to protect data during transmission?
The process is used by all the payment companies and banks for secure data transfer.The information once sent through network can be hacked in and leaked.The process to protect that is called Encryption.The Encryption are of different levels like 72 bit 128 bit.
What computer network tool is used to test whether a particular host is reachable across an IP network?
Ping
What type of network is WAN?
A wide area network (WAN) is a telecommunication network that covers a broad area (i.e., any network that links across metropolitan, regional, or national boundaries).
What encoding scheme does a WAN use?
Wide Area Networks (WANs) commonly use several encoding schemes, with one of the most prevalent being the Packet Mode, where data is encapsulated into packets for transmission. Other encoding schemes include Frame Relay, Asynchronous Transfer Mode (ATM), and MPLS (Multiprotocol Label Switching), which help optimize data flow and ensure efficient delivery over long distances. Additionally, depending on the technology, WANs may also utilize encoding techniques like Manchester or Differential Manchester encoding for signaling purposes. These schemes facilitate reliable communication and enhance the efficiency of data transfer across the network.
What is Bit-Encoding?
Bit encoding is a method of representing data using binary digits (bits), typically in the form of sequences of 0s and 1s. This encoding is fundamental in digital communications and computing, as it allows for the efficient storage and transmission of information. Different encoding schemes, such as ASCII or UTF-8, are used to convert characters and symbols into their corresponding binary representations. Bit encoding plays a crucial role in ensuring data integrity and compatibility across various systems and devices.
What are the criteria for good encoding?
Good encoding should prioritize clarity, efficiency, and compatibility. Clarity ensures that the encoded data is easily understandable and can be accurately interpreted by both humans and machines. Efficiency involves minimizing the size of the encoded data while maintaining quality, optimizing storage and transmission. Compatibility ensures that the encoding format can be widely used and supported across different platforms and applications.
What is scrambling codes?
Scrambling codes are unique sequences used in communication systems, particularly in CDMA (Code Division Multiple Access) networks, to differentiate between multiple users accessing the same frequency channel. They help to spread the signal across a wider bandwidth and mitigate interference by effectively randomizing the data before transmission. This ensures that the receiver can accurately decode the intended signal while filtering out noise and other users' signals. Scrambling codes enhance system capacity and improve the overall quality of communication.
What two ways can a unit of data be sent across a network?
1 tcp transmission control protocol 2 udp protocol
What network component request services across the network?
A client requests services across a network.
Which layer arranges the transmission of a data frames bits when they are dispatched across the network?
The Data Link layer is responsible for arranging the transmission of data frames' bits when they are dispatched across the network. It ensures reliable transfer of data frames between directly connected nodes by managing error detection and correction, as well as framing and addressing. This layer operates above the Physical layer, which handles the actual transmission of raw bit streams over the physical medium.
What is frasible distance fd?
Frasible Distance (FD) is the maximum distance a data frame can travel across a network without encountering errors or signal degradation. It is determined by the network's capabilities, such as the transmission medium and the signaling rate. FD helps ensure reliable data transmission over a network by setting a limit on how far a signal can travel before needing regeneration.
Select 3 ways to recognize that the network is working?
1) Data can be passed across the network. 2) Multiple devices are seen and accessible across the network. 3) The internet can be accessed across the network.
What is the maximum transmission unit?
The Maximum Transmission Unit (MTU) is the largest size of a packet that can be transmitted over a network protocol. It is measured in bytes and varies depending on the network technology; for example, Ethernet typically has an MTU of 1500 bytes. Setting the MTU correctly is crucial for optimizing network performance and avoiding fragmentation, which can lead to inefficiencies and increased latency. Adjusting the MTU can help improve the reliability and speed of data transmission across different types of networks.
