Test: Data Communication - 2 - CUET Humanities MCQ

Flow control prevents a fast sender from flooding a slow receiver with data by regulating flow of data on communication lines.

ICMP in data communication serves as a supplement to IP and informs the sender about any accident that occurs to its packets.

Simplex communication is a communication channel that sends information in one direction only. As per the International Telecommunication Union definition, simplex communication is a communications channel that operates in one direction at a time, but that may be reversible; this is termed half duplex in other contexts.

The correct answer is file server.
Key Points:

• A file server is used to manage files on a server where it can be uploaded, shared or downloaded by other available systems which are connected to that network.
• It is a central server on a computer network that enables connected clients to access the server's storage capacities.
• File servers offer users a central storage place for files on internal data media, which is available to all approved clients.
• The server administrator defines strict guidelines regarding which client have which access rights. For example, the design or file authorizations of the particular file system empower the administrator to set which files can be seen and opened by a specific client or client group.
• With file servers connected with the web and designed appropriately, clients can't just access the files through the neighborhood organization but also benefit from remote access.
• This enables files to be accessed and saved on the file server even when users are on the go.
• All modern operating systems such as Windows, Linux, or macOS can be used on a file server, although the devices available in the network need to be compatible with the operating system.

A server is the device on the computer network that manages all the network resources. A client is a computer that sends request to the server.

Fiber optic cable is the fastest and most accurate cable. It transmits signal in the form of light. Fiber optic cable works on the principle of total internal reflection.

SMTP is Simple Mail Transfer Protocol.

One of the earliest guided transmission media is twisted pair cables. A twisted pair cable comprises two separate insulated copper wires, which are twisted together and run in parallel. The copper wires are typically 1 mm in diameter. One of the wires is used to transmit data and the other is the ground reference.

This is a simplex device, in which communication can be performed in only one direction.

Microwaves are the electromagnetic radiations with wavelengths ranging from one meter to one millimeter and with frequencies ranging between 300 MHz (100 cm) and 300 GHz (0.1 cm).
