Answer:
Option b = "is stored in ROM to ensure to avoid any infection from viruses. "
Explanation:
In order to to understand the fundamentals of an Operating system in computer one needs to know what the bootstrap program is.
The BOOTSTRAP PROGRAM is first program that will run when the computer is switched on, thus the program( the BOOTSTRAP PROGRAM) will be the program to open the OPERATING SYSTEM.
The device in laptops and personal computers known as ROM is an acronym that stands for Read-Only Memory and it is a storage medium. Because of ROM inability to get Virus it is used in the storage of Bootstrap program.
Answer:
On the basis of size there are four types of computer. They are minicomputer, micro computer, mainframe computer and super computer. Super computer is the fastest, most expensive, big in size, and most powerful computer that can perform multiple tasks within no second.
Answer:
1) Readability is the ease with which a reader can understand a written text. Readability is more than simply legibility—which is a measure of how easily a reader can distinguish individual letters or characters from each other.
2) Navigation is a field of study that focuses on the process of monitoring and controlling the movement of a craft or vehicle from one place to another. The field of navigation includes four general categories: land navigation, marine navigation, aeronautic navigation, and space navigation. It is also the term of art used for the specialized knowledge used by navigators to perform navigation tasks.
3) In classical deductive logic, a consistent theory is one that does not entail a contradiction. The lack of contradiction can be defined in either semantic or syntactic terms. The semantic definition states that a theory is consistent if it has a model, i.e., there exists an interpretation under which all formulas in the theory are true. This is the sense used in traditional Aristotelian logic, although in contemporary mathematical logic the term satisfiable is used instead.
4) The way in which the parts of something are arranged or laid out.
5) Typography is the art and technique of arranging type to make written language legible, readable and appealing when displayed. The arrangement of type involves selecting typefaces, point sizes, line lengths, line-spacing (leading), and letter-spacing (tracking), and adjusting the space between pairs of letters (kerning ).

Once enough charge has been separated in a growing storm, a lightning flash can occur. These normally travel within or between clouds (abbreviated CC) or from cloud to ground (CG). Most storms produce more CC than CG flashes--about six times as many in tropical storms and two times as many in midlatitudes. Sometimes a flash will travel from cloud to air or simply occur within "clear" air.
Exactly what triggers flashes is still uncertain and an area of continued research. It seems that very concentrated electric fields (perhaps at the ends of pointed surfaces or single particles) are needed to accelerate charged particles, or ions. Once moving with sufficient energy, the ions appear to blaze a path toward opposite charge in cascading fashion.
