What is Multiple Access?

Detailed Solution for Test: Networking- 1 - Question 3
What is Multiple Access?

  • Definition: Multiple Access refers to the ability of multiple nodes to share the same physical communication channel simultaneously.

  • Types: There are several types of multiple access techniques such as Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), and Space Division Multiple Access (SDMA).

  • Shared Links: In multiple access, if the physical links are shared by more than two nodes, it is considered as multiple access.

  • Efficiency: Multiple access allows for efficient utilization of the network resources by enabling multiple users to transmit data over a shared channel.

  • Applications: Multiple access is commonly used in wireless communication systems, satellite communication, and local area networks (LANs) to facilitate simultaneous communication among multiple users.

The computer network is
Detailed Solution for Test: Networking- 1 - Question 4
Explanation:

  • Computer network: A computer network is a group of computers connected to share information and resources.

  • Network computer with cable: This refers to a wired network where computers are connected using cables, such as Ethernet cables.

  • Network computer without cable: This refers to a wireless network where computers are connected without the use of cables, typically using Wi-Fi technology.

  • Both of the above: This option means that the computer network can include both wired and wireless connections, depending on the setup and requirements.


Detailed solution:

  • A computer network can be set up in various ways, depending on the needs of the users and the environment.

  • Wired networks are often more reliable and secure, as the physical cables provide a direct connection between devices.

  • Wireless networks offer more flexibility and convenience, allowing users to connect to the network without being physically tethered to a cable.

  • Many modern networks use a combination of wired and wireless connections to provide the best of both worlds.

  • Therefore, the correct answer is option C: Both of the above, as a computer network can include both wired and wireless connections.

FTP stands for
Detailed Solution for Test: Networking- 1 - Question 5
FTP Overview

  • FTP: Stands for File Transfer Protocol


Explanation

  • File Transfer Protocol (FTP): is a standard network protocol used for the transfer of computer files between a client and server on a computer network.

  • Function: FTP is commonly used to upload and download files from a server over a network, such as the Internet.

  • Authentication: Users typically need to enter a username and password to access an FTP server and transfer files.

  • Security: While FTP is widely used, it is not a secure protocol as data is transmitted in plaintext, making it vulnerable to interception. SFTP (SSH File Transfer Protocol) and FTPS (FTP Secure) are more secure alternatives to FTP.

Which of the following are network services?
Detailed Solution for Test: Networking- 1 - Question 6
Network Services

  • File Service: This service allows users to access and manage files stored on a network server. Users can share, upload, download, and modify files across the network.


  • Print Service: Print services enable users to send print jobs to network printers from their devices. This allows for centralized printing and sharing of printing resources.


  • Database Service: Database services involve accessing and managing databases stored on a network server. Users can query, update, and interact with the database over the network.


  • All of the Above: All the mentioned services - file service, print service, and database service - are examples of network services that provide specific functionalities to users over a network.


By offering these network services, organizations can enhance collaboration, efficiency, and accessibility for users working within a networked environment. Each service plays a crucial role in enabling users to perform various tasks and access resources across the network.

FDDI stands for
Detailed Solution for Test: Networking- 1 - Question 7
Explanation:

  • FDDI stands for: Fiber Distributed Data Interface


Detailed

  • Fiber Distributed Data Interface (FDDI) is a standard for data transmission in a local area network (LAN) that uses optical fiber as the primary medium.

  • FDDI was designed to provide high-speed and reliable communication for demanding applications such as backbone networks.

  • The key features of FDDI include:

    • Dual counter-rotating rings for redundancy and fault tolerance.

    • Support for both voice and data transmission.

    • High data transfer rates up to 100 Mbps.

    • Scalability to support a large number of nodes.



  • Overall, FDDI is a robust and reliable networking technology that was widely used in the 1980s and 1990s for high-performance LANs.

Which is the main function of transport layer?
Detailed Solution for Test: Networking- 1 - Question 8
Main Function of Transport Layer:

  • End to end delivery: The main function of the transport layer is to ensure end-to-end delivery of data between two communicating devices.

  • Node to node delivery: The transport layer is responsible for delivering data from one node to another node in a network.

  • Synchronization: The transport layer also helps in synchronizing data transmission between devices to ensure reliable communication.

  • Updating and maintaining routing tables: Contrary to the statement, updating and maintaining routing tables is not a function of the transport layer. It is typically handled by the network layer in the OSI model.


By focusing on end-to-end delivery, the transport layer plays a crucial role in ensuring that data is successfully transmitted between devices in a network. It manages the flow of data, error checking, and retransmission of lost packets to guarantee reliable communication. Additionally, the transport layer also handles segmentation and reassembly of data packets to optimize transmission efficiency.

TCP/IP ______ layer corresponds to the OSI models to three layers.
Detailed Solution for Test: Networking- 1 - Question 9
Explanation:

  • TCP/IP Model vs. OSI Model:

    • The TCP/IP model is a four-layer model that corresponds to the OSI model's seven layers.

    • The TCP/IP Application layer corresponds to the OSI Application, Presentation, and Session layers combined.



  • Layers in TCP/IP Model:

    • Application Layer: The top layer of the TCP/IP model deals with application-level protocols and services.

    • Transport Layer: The layer responsible for end-to-end communication and error-checking.

    • Internet Layer: Handles routing and addressing in the network.

    • Network Interface Layer: The lowest layer deals with physical connections and data transfer.



  • Correspondence to OSI Model:

    • The TCP/IP Application layer corresponds to the OSI Application layer, which is responsible for user interfaces and application-level protocols.

    • In the OSI model, the Presentation layer deals with data translation and encryption, while the Session layer manages connections.

    • Therefore, the TCP/IP Application layer combines the functions of the OSI Application, Presentation, and Session layers.

Which of the following applications allows a user to access and change remote files without actual transfer?
Detailed Solution for Test: Networking- 1 - Question 10
Accessing and Changing Remote Files Without Actual Transfer

  • NFS (Network File System): NFS allows a user to access and change remote files without actual transfer by mounting remote directories on the local system. This means that the user can work with files located on a remote server as if they were stored locally.

  • DNS (Domain Name System): DNS is a system that translates domain names into IP addresses, it does not allow users to access or change remote files without transferring them.

  • FTP (File Transfer Protocol): FTP is a protocol used for transferring files between a client and a server, it involves actual file transfer rather than accessing and changing remote files without transfer.

  • Telnet: Telnet is a protocol used for remote access to servers, but it does not provide a way to access and change remote files without actual transfer.
