Which device is designed to send packets using package addresses?
(A) Specialty Hub
(B) switching hub
(C) Port Hub
(D) filtering hub
Correct Answer : B
Explanation :
A switching hub, also known as a network switch, is designed to send packets using package addresses. A network switch operates at the data link layer of the OSI model and uses MAC addresses to forward data frames to specific devices within a local area network (LAN). Unlike a hub, which simply broadcasts data to all devices in the network, a switch intelligently forwards packets only to the device intended to receive the data, increasing network efficiency and reducing unnecessary network traffic.
Which cobble is used to send modulated light?
(A) Category 3 UTP
(B) Category 5 UTP
(C) fiber
(D) coax
Correct Answer : C
Explanation :
It seems there might be a confusion in your question. If you are referring to the technology used for transmitting data using modulated light, the term you are looking for is "fiber optic cable" or simply "fiber." Fiber optic cables are thin, flexible strands of glass or plastic that transmit data as modulated light pulses. They are widely used for high-speed data transmission over long distances due to their ability to carry large amounts of data with low attenuation and high bandwidth capabilities.
Which components are used in LAN for Ethernet?
(A) COAX
(B) Fiber
(C) STP
(D) All of the above
Correct Answer : D
Explanation :
All three components—COAX (coaxial cables), Fiber (optical fiber cables), and STP (shielded twisted pair cables)—can be used in LANs for Ethernet connectivity, depending on specific network requirements and conditions. Different types of Ethernet cables, including coaxial, fiber optic, and shielded twisted pair, are used based on factors such as data transfer speed, distance, and susceptibility to electromagnetic interference.
Which statement is true for Router and Wretch?
(A) Wretch connects two networks at data link layer
(B) Router is more useful
(C) Router connects two networks at the Network Layer.
(D) both (a) and (c)
Correct Answer : D
Array is used for-
(A) To store the value in memory
(B) To delete the value in memory
(C) for output
(D) all of the above
Correct Answer : D
Explanation :
An array is used to store values in memory. Arrays allow you to store multiple values of the same data type under a single variable name, making it easier to manage and manipulate data in programming. Arrays are commonly used in various programming languages for tasks such as storing collections of data, performing calculations on large sets of values, and iterating through elements to process them. Arrays are not used for deleting values in memory or for output; their primary purpose is to store and organize data.
With which of the following is the Break statement used?
(A) if Statement
(B) else if Statement
(C) Switch Statement
(D) None of these
Correct Answer : C
Explanation :
The break statement is used with loops (such as for and while loops) and switch statements in programming. In loops, it is used to exit the loop prematurely, while in a switch statement, it is used to exit the switch block after executing a specific case.
