Answer:Optical fiber has the highest transmission in network.
point-to-point connection
A personal area network (PAN) is a computer network for interconnecting devices centered on an individual person's workspace. A PAN provides data transmission among devices such as computers, smartphones, tablets and personal digital assistants. A PAN may be wireless or carried over wired interfaces such as USB.
Time Division Multiplexing
A set of rules that governs data communication is called protocol. It represents an agreement to adopt to pre-specified rules by the devices that are set up to communicate with one another. These rules also determine how the data gets transmitted from the encoding stage to the decoding stage.
Which address is used to identify a process on a host by the transport layer? Explanation: A port number is a way to identify a specific process to which an Internet or other network message is to be forwarded when it arrives at a server.
Which one of the following is a file transfer protocol using SSH? Explanation: SCP (Secure copy protocol), SFTP (SSH File Transfer Protocol) and Rsync all are file transfer protocols which are used by SSH.
In Simplex mode, the communication is unidirectional, as on a one-way street. Only one of the two devices on a link can transmit, the other can only receive. The simplex mode can use the entire capacity of the channel to send data in one direction.
There are three modes of transmission, namely: simplex, half duplex, and full duplex. The transmission mode defines the direction of signal flow between two connected devices.
Parallel transmission is commonly used to transfer data from computer to printer. (ii) Serial Transmission: In serial data transmission, a group of bits of data flow in sequential Order through single communication line. The flow of traffic on one-lane residential street is an example of serial data transmission mode.
Full-duplex data transmission means that data can be transmitted in both directions on a signal carrier at the same time. For example, on a local area network with a technology that has full-duplex transmission, one workstation can be sending data on the line while another workstation is receiving data.
Answer: Network protocols are needed because it include mechanisms for devices to identify and make connections with each other, as well as formatting rules that specify how data is packaged into messages sent and received.
In a full-duplex system, both parties can communicate with each other simultaneously. An example of a full-duplex device is a telephone; the parties at both ends of a call can speak and be heard by the other party simultaneously.
Transmission mode refers to the mechanism of transferring of data between two devices connected over a network. It is also called Communication Mode. There are three types of transmission modes. They are: Simplex Mode.
The main difference between simplex, half duplex, and full duplex is that in a simplex mode of transmission the communication is unidirectional whereas, in the half-duplex mode of transmission the communication is two directional but the channel is alternately used by the both the connected device.
Data communication refers to the exchange of data between a source and a receiver via form of transmission media such as a wire cable. Data communication is said to be local if communicating devices are in the same building or a similarly restricted geographical area.
Common Internet protocols include TCP/IP (Transmission Control Protocol/Internet Protocol), UDP/IP (User Datagram Protocol/Internet Protocol), HTTP (HyperText Transfer Protocol) and FTP (File Transfer Protocol). TCP/IP is a stream protocol. This means that a connection is negotiated between a client and a server.
An access point is a device that creates a wireless local area network, or WLAN, usually in an office or large building. An access point connects to a wired router, switch, or hub via an Ethernet cable, and projects a Wi-Fi signal to a designated area.
Explanation: The only difference between OSI model and TCP/IP model is that in OSI model two layers namely Presentation and Session layer have been added. Explanation: Not only application layer, but presentation layer, session layer and transport layer are also implemented in the end system.
Which one of the following is a transport layer protocol used in networking? Explanation: Both TCP and UDP are transport layer protocol in networking. TCP is an abbreviation for Transmission Control Protocol and UDP is an abbreviation for User Datagram Protocol. TCP is connection oriented whereas UDP is connectionless.
The DNS is responsible for translating these domain names to the IP addresses. The DNS is a worldwide network that collectively forms a database of domain names and IP addresses. This database is a global one. The hierarchy consists of DNS servers.
Gateway device is used to connect two system, especially if the system use different protocols. Unlike less advanced network hubs, a network switch forwards data only to one or multiple devices that need to receive it, rather than broadcasting the same data out of each of its ports. It works on OSI layer 2.
Congestion Control. Congestion control is a network layer issue, and is thus concerned with what happens when there is more data in the network than can be sent with reasonable packet delays, no lost packets, etc. Flow control is a local, congestion control is global.
A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions on the Internet.
Using the Internet, computers connect and communicate with one another, primarily using the TCP/IP (Transmission Control Protocol / Internet Protocol). Think of TCP/IP as a book of rules, a step-by-step guide that each computer uses to know how to talk to another computer.
Network technologies allow two or more computers to connect with each other. The most common of these technologies include Local Area Network (LAN), Wireless Area Network (WAN), the Internet via client servers and Bluetooth.
If you have two PCs that you want to network but no router, you can connect them using an Ethernet crossover cable or establish an ad-hoc wireless network if they have Wi-Fi hardware. You can do anything you could on a normal network after hooking them up, including sharing files and printers.
A computer network is mainly of four types:
- LAN(Local Area Network)
- PAN(Personal Area Network)
- MAN(Metropolitan Area Network)
- WAN(Wide Area Network)
The system bus is a pathway composed of cables and connectors used to carry data between a computer microprocessor and the main memory. The bus provides a communication path for the data and control signals moving between the major components of the computer system.
To find computers connected to your PC through a network, click the Navigation Pane's Network category. Clicking Network lists every PC that's connected to your own PC in a traditional network. Clicking Homegroup in the Navigation Pane lists Windows PCs in your Homegroup, a simpler way to share files.
Connectivity. When one computer can connect to one or many other computers and share information and resources.
Definition: A connectivity device to which network cables are attached to form a network segment. Hubs typically do not filter data, but instead retransmit incoming data packets or frames to all parts. Almost all networks today use a central hub or switch to which the computers on the network connect.
