The IBM system/370 architecture uses a two-level memory structure and refers to the two levels as segments and pages, although the segmentation approach lacks many of the features described in Chapter 8. For the basic 370 architecture, the page size may be either 2 KB or 4 KB, and the segment size is fixed at either 64 KB or 1 MB. For the 370/XA and 370/ESA architectures, the page size is 4 KB and the segment size is 1 MB. What advantages of segmentation does this scheme lack

Answers

Answer 1

Answer:

Explanation:

Introductory thought:  

Thinking about the architecture for the IBM System/370 that is fit for giving higher preparing force and more stockpiling limit since it utilizes two-level of memory structure which is known as the segments and caches and the given plan is as per the following:  

In division the address space is isolated into quantities of segments of variable sizes and then again in paging the address space is partitioned into quantities of fixed-sized units that are known as pages.It is more helpful for better utilization of memory. The fundamental architecture for the IBM system/370 architecture the size of the page are for the most part either 2KiloBytes (KB) or 4KB and the size of the segments will be changed from 64KiloBytes to 1MegaBytes.   The two dissimilar kinds of architecture that existed are 370/XA that is the Extended Architecture, also the other is 370/ESA known as the Enterprise Systems Architecture.    The page size is 4KB for the Extended variant and 1MB for the Enterprise Systems Architecture (ESA).

Advantages of segmentation that the given scheme needs to incorporate includes:

In the configuration of the architecture for IBM System/370 the segments are of a fixed size which isn't noticeable for the programmer and as such he will know the interior subtleties and subsequently inside architecture is stowed away from outside gentle.  In IBM system/370 the reference bit is zero for the processor hardware as well as at whatever point another page is stacked into the edge, the reference bit is changed to one after referring to a specific area inside the casing.  The quantity of lines of the page outline table is overseen by the Operating System and a page outline table section is moved to start with one line then onto the next depending on the length of the span of the referenced bit from the page outline which is sets to nothing. Whenever there is a need to supplant the page then the page browsed the line of the longest life non referenced edges.

what was his beliefs?

Answers

A belief is an attitude that something is the case, or that some proposition about the world is true.[1] In epistemology, philosophers use the term "belief" to refer to attitudes about the world which can be either true or false.[2] To believe something is to take it to be true; for instance, to believe that snow is white is comparable to accepting the truth of the proposition "snow is white". However, holding a belief does not require active introspection. For example, few carefully consider whether or not the sun will rise tomorrow, simply assuming that it will. Moreover, beliefs need not be occurrent (e.g. a person actively thinking "snow is white"), but can instead be dispositional (e.g. a person who if asked about the color of snow would assert "snow is white").[2]

There are various different ways that contemporary philosophers have tried to describe beliefs, including as representations of ways that the world could be (Jerry Fodor), as dispositions to act as if certain things are true (Roderick Chisholm), as interpretive schemes for making sense of someone's actions (Daniel Dennett and Donald Davidson), or as mental states that fill a particular function (Hilary Putnam).[2] Some have also attempted to offer significant revisions to our notion of belief, including eliminativists about belief who argue that there is no phenomenon in the natural world which corresponds to our folk psychological concept of belief (Paul Churchland) and formal epistemologists who aim to replace our bivalent notion of belief ("either we have a belief or we don't have a belief") with the more permissive, probabilistic notion of credence ("there is an entire spectrum of degrees of belief, not a simple dichotomy between belief and non-belief").[2][3]

Beliefs are the subject of various important philosophical debates. Notable examples include: "What is the rational way to revise one's beliefs when presented with various sorts of evidence?"; "Is the content of our beliefs entirely determined by our mental states, or do the relevant facts have any bearing on our beliefs (e.g. if I believe that I'm holding a glass of water, is the non-mental fact that water is H2O part of the content of that belief)?"; "How fine-grained or coarse-grained are our beliefs?"; and "Must it be possible for a belief to be expressible in language, or are there non-linguistic beliefs?".[2]

Write a full class definition for a class named GasTank , and containing the following members:
A data member named amount of type double.
A constructor that no parameters. The constructor initializes the data member amount to 0.
A function named addGas that accepts a parameter of type double . The value of the amount instance variable is increased by the value of the parameter.
A function named useGas that accepts a parameter of type double . The value of the amount data member is decreased by the value of the parameter. However, if the value of amount is decreased below 0 , amount is set to 0 .
A function named isEmpty that accepts no parameters and returns a boolean value. isEmpty returns a boolean value: true if the value of amount is less than 0.1 , and false otherwise.
A function named getGasLevel that accepts no parameters. getGasLevel returns the value of the amount data member.
class GasTank
{
private:
double amount;
public:

bool GasTank::isEmpty(){if(amount < .1) return true; else return false;}
double GasTank::getGasLevel() {return amount;}

Answers

Answer:

Explanation:

The following class code is written in Java and includes all of the required methods as requested in the question...

package sample;

class GasTank {

   private double amount = 0;

   private double capacity;

   public GasTank(double initialAmount) {

       this.capacity = initialAmount;

   }

   public void addGas(double addAmount) {

       this.amount += addAmount;

       if (amount > capacity) {

           amount = capacity;

       }

   }

   public void useGas(double subtractAmount) {

       this.amount -= subtractAmount;

       if (amount < 0) {

           amount = 0;

       }

   }

   public boolean isEmpty() {

       return (amount < 0.1);

   }

   public boolean isFull() {

       return (amount > capacity - 0.1);

   }

   public double getGasLevel() {

       return amount;

   }

   public double fillUp() {

       double difference = capacity - amount;

       amount = capacity;

       return difference;

   }
