[#436] RAM is used as a short memory because it is
Correct Answer

(A) Volatile

Explanation

Solution: Volatile memory : Volatile memory, in contrast to non-volatile memory, is computer memory that requires power to maintain the stored information; it retains its contents while powered on but when the power is interrupted, the stored data is quickly lost. Volatile memory has several uses including as main memory.

[#437] A modern electronic computer is a machine that is meant for
Correct Answer

(B) Input storage, manipulation of outputting of data
(F) input, storage, manipulation and outputting of data

Explanation

Solution: A modern electronic computer is a machine that is meant for Input storage, manipulation of outputting of data. The processor, more formally known as the central processing unit (CPU), has the electronic circuitry that manipulates input data into the information people want.

[#438] Which is a device that changes information into digital form?
Correct Answer

(B) Digitizer

Explanation

Solution: A graphic tablet (also known as a digitizer, drawing tablet, drawing pad, digital drawing tablet, pen tablet, or digital art board) is a computer input device that enables a user to hand-draw images, animations and graphics, with a special pen-like stylus, similar to the way a person draws images with a pencil and paper. These tablets may also be used to capture data or handwritten signatures. It can also be used to trace an image from a piece of paper which is taped or otherwise secured to the tablet surface. Capturing data in this way, by tracing or entering the corners of linear poly-lines or shapes, is called Digitizing .

[#440] Which network is a packet switching network?
Correct Answer

(D) EuroNET

Explanation

Solution: * A network is a way for computers to connect and share information. * Packet switching is a method of breaking down data into small pieces called packets before sending them across the network. These packets are then reassembled at the destination. It's like sending a book page by page instead of the entire book at once. This makes the network more efficient. Now let's look at the options: * Ring network, Star network and LAN (Local Area Network) : These describe how computers are connected, but don't inherently tell us if they use packet switching. * EuroNET : EuroNET was specifically designed as a packet-switching network . * None of the above : This would only be correct if none of the other options used packet switching. Therefore, the correct answer is EuroNET because it was designed to use packet switching.
