Answer with Explanation

Ans (1): Warm booting

Alternatively referred to as a soft boot, a warm boot is a method of restarting a computer that is already on without completely turning the computer off. On a computer running Windows, a warm boot can be accomplished by pressing the Ctrl + Alt + Del keys simultaneously or by selecting a restart option within Windows. A warm boot is faster than turning a computer off and on again (cold boot) and is done when your computer needs to restart, and you plan on continuing to use the computer.

Answer with Explanation

Ans (3): Only (A), (B) and (C)

A high-level language (HLL) is a programming language such as C, FORTRAN, or Pascal that enables a programmer to write programs that are more or less independent of a particular type of computer. Such languages are considered high-level because they are closer to human languages and further from machine languages.

Answer with Explanation

Ans (3): Hardware

A hard disk drive (HDD), hard disk, hard drive or fixed disk is a data storage device used for storing and retrieving digital information using one or more rigid rapidly rotating disks (platters) coated with magnetic material. The platters are paired with magnetic heads arranged on a moving actuator arm, which read and write data to the platter surfaces. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. HDDs are a type of non-volatile memory, retaining stored data even when powered off.

Answer with Explanation

Ans (1): Laser printer

A laser printer is a popular type of personal computer printer that uses a non-impact (keys don't strike the paper), photocopier technology.

Answer with Explanation

Ans (1): Experts

JPEG stands for Joint Photographic Experts Group, which created this standard for this type of image formatting. JPEG files are images that have been compressed to store a lot of information in a small-size file. Most digital cameras store photos in JPEG format, because then you can take more photos on one camera card than you can with other formats. A JPEG is compressed in a way that loses some of the image detail during the compression in order to make the file small (and thus called “lossy” compression).

Answer with Explanation

Ans (5): MIPS

MIPS measures roughly the number of machine instructions that a computer can execute in one second.

Answer with Explanation

Ans (4): High Level Language

A high-level language is a programming language such as C, FORTRAN, or Pascal that enables a programmer to write programs that are more or less independent of a particular type of computer. Such languages are considered high-level because they are closer to human languages and further from machine languages.

Answer with Explanation

Ans (2): Grammar mistake

Red underlines indicate spelling errors, green underlines are grammar errors, and blue underlines indicate inconsistent formatting.

Answer with Explanation

Ans (2): Disk Defragmenter

Disk Defragmenter is a utility in Microsoft Windows designed to increase access speed by rearranging files stored on a disk to occupy contiguous storage locations, a technique called defragmentation. Defragmenting a disk minimizes head travel, which reduces the time it takes to read files from and write files to the disk. Beginning with Windows XP, Disk Defragmenter also reduces system startup times

Answer with Explanation

Ans (1): Medium Scale Integrated Circuits

The early integrated circuits were SSI. The next step in the development of integrated circuits, taken in the late 1960s, introduced devices which contained hundreds of transistors on each chip, called “medium-scale integration” (MSI).

Answer with Explanation

Ans (2): Search Engine

A web search engine is a software system that is designed to search for information on the World Wide Web. The search results are generally presented in a line of results often referred to as search engine results pages (SERPs). The information may be a mix of web pages, images, and other types of files. Some search engines also mine data available in databases or open directories. Unlike web directories, which are maintained only by human editors, search engines also maintain real-time information by running an algorithm on a web crawler.

Answer with Explanation

Ans (3): Versatility

Versatility in computer means it is capable of performing almost any task, provided the task can be reduced to a series of logical steps.

Answer with Explanation

Ans (2): Microsoft

MS-DOS is a discontinued operating system for x86-based personal computers mostly developed by Microsoft. Collectively, MS-DOS, its rebranding as IBM PC DOS, and some operating systems attempting to be compatible with MS-DOS, are sometimes referred to as “DOS” (which is also the generic acronym for disk operating system). MS-DOS was the main operating system for IBM PC compatible personal computers during the 1980s and the early 1990s, when it was gradually superseded by operating systems offering a graphical user interface (GUI), in various generations of the graphical Microsoft Windows operating system.

Answer with Explanation

Ans (4): Fourth generation

The microprocessor brought the fourth generation of computers, as thousands of integrated circuits were built onto a single silicon chip.

Answer with Explanation

Ans (2): Word Processors

A word processor is an electronic device or computer software application that performs the task of composing, editing, formatting, and printing of documents. It is not to be mistaken for a text editor, which does not save any formatting in each document.
