Explanation:
The standard punch card (for computers) was invented and developed by Herman Hollerith. But the idea of punch cards was already long invented, used to control Jacquard looms.
Jacquard looms were looms that used punch cards to control the pattern a loom weaves.
The idea of punch cards in Jacquard looms also influenced Charles Babbage, who decided to use punched cards to control the sequence of computations in his proposed analytical engine. Unlike Hollerith's cards of 50 years later, which were handled in decks like playing cards, Babbage's punched cards were to be strung together.
Answer:
B. a tag
Explanation:
In the structure definition given below:
struct Employee
{
string name;
int idNum;
};
Employee corresponds to the tag of the structure. The tag is used to create additional instances of the structure. For example:
struct Employee e1;
struct Employee e2;
name and idNum are members of the Employee structure and are referenced using the dot notation. e.g.,
struct Employee e1;
e1.idNum=1;
Answer:
Explanation:
temporal locality can be defined as: when a particular memory is referenced or accessed several times within a specific period of time. In the question, i think the variable that exhibit temporal locality are I, J and 0(all the variable). This is because the variable J and 0 are accessed several times within the loop. I would not have been part of it, but in the A[I][J]=B[I][0]+A[J][I], the variable "I" is also accessed in the addition. this is why it is part of the temporal locality.
Many people use relative location on a daily basis by using B) their mental maps of an area.
You know what a certain area looks like, at least approximately, so you don't need to use these other options on a day to day basis. You can rely on your mental maps to do the work for you.
