Correct Answer :   Random Access Memory

---

Random Access Memory (RAM) is a form of computer data storage. A random-access device allows stored data to be accessed in very nearly the same amount of time for any storage location, so data can be accessed quickly in any random order. In contrast, other data storage media read and write data only in a predetermined order.

Correct Answer :   hyper text transfer protocol

---

The Hyper Text Transfer Protocol (HTTP) is an application protocol for distributed, collaborative, hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web. HTTP is the protocol to exchange or transfer hypertext.

Correct Answer :   Multimedia

---

Multimedia is media and content that uses a combination of different content forms. This contrasts with media that use only rudimentary computer displays such as text-only or traditional forms of printed or hand-produced material. Multimedia includes a combination of text, audio, still images, animation, video, or interactivity content forms.

Correct Answer :   they do not generate magnetic fields

---

Optical fibers are used instead of metal wires because signals travel along them with less loss and are also immune to electromagnetic interference. Besides, there are no radiated magnetic fields around optical fibers; the electromagnetic fields are confined within the fiber. Since fiber optics do not radiate electromagnetic energy, emissions cannot be intercepted.

Correct Answer :   Morphing

---

Morphing is a special effect in motion pictures and animations that changes (or morphs) one image into another through a seamless transition. Most often it is used to depict one person turning into another through technological means or as part of a fantasy or surreal sequence.

Correct Answer :   laser beam

---

Data is stored on the disc as a series of microscopic indentations. A laser is shone onto the reflective surface of the disc to read the pattern of pits and lands. Because the depth of the pits is approximately one-quarter to one-sixth of the wavelength of the laser light used to read the disc, the reflected beam's phase is shifted in relation to the incoming beam, causing destructive interference and reducing the reflected beam's intensity. This pattern of changing intensity of the reflected beam is converted into binary data.

Correct Answer :   Storage

---

In a computer, storage is the place where data is held in an electromagnetic or optical form for access by a computer processor. It is a technology consisting of computer components and recording media used to retain digital data. It is a core function and fundamental component of computers.

Correct Answer :   Printer

---

A parallel port can be used to connect a large number of devices. The most common usage was for printers, although scanners, external disk drives, and network adapters also used this port. With a special cable, two computers could also be connected directly for sharing files.

Correct Answer :   Psychology

---

A spreadsheet is an interactive computer application program for organization and analysis of information in tabular form. Spreadsheets developed as computerized simulations of paper accounting worksheets. The program operates on data represented as cells of an array, organized in rows and columns. Each cell of the array is a model–view–controller element that can contain either numeric or text data, or the results of formulas that automatically calculate and display a value based on the contents of other cells. It is more useful in Statistics.

Correct Answer :   Charles Babbage

---

Charles Babbage, was an English mathematician, philosopher, inventor and mechanical engineer who originated the concept of the programmable computer. Considered as “father of the computer”, Babbage is credited with inventing the first mechanical computer that eventually led to more complex designs.
