Semiconductor memory is used mainly for primary storage even with its high cost. In another hand, the magnetic tape is the cheap

est storage media and it is commonly preferred only as backup storage! Use your own words to discuss how the storage cost, speed and capacity trade-offs can affect the choice of storage media.

<span>Storage costs are a big factor in choosing the type of storage media, especially for larger projects and firms. Tasks that require large backups tend to move to magnetic (tape) memory because of the relatively low cost and high overall storage capacity. However, when working with projects that require faster memory and access that is instantaneous, chip memory, even at the higher cost, is more preferable since it is always accessible.</span>

Most types of semiconductor memory have the property of random access,which means that it takes the same amount of time to access any memory location. This means that data can efficiently be accessed in any random order.This contrasts with data storage media such as hard disks and CDs which read and write data consecutively therefore, explains why the data can only be accessed in the same sequence it was written.

Semiconductor memory also has much faster access times than other types of data storage; a byte of data can be written to or read from semiconductor memory within a few nanoseconds, while access time for rotating storage such as hard disks is in the range of milliseconds. For these reasons it is used for main computer memory (primary storage), to hold data the computer is currently working on, among other uses.

Storage costs are a big factor in choosing the type of storage media, especially for larger projects and firms. Tasks that require large backups tend to move to magnetic (tape) memory because of the relatively low cost and high overall storage capacity. However, when working with projects that require faster memory and access that is instantaneous, chip memory, even at a higher cost, is more preferable since it is always accessible.

In which slot is a video card most commonly installed within a laptop?
IgorLugansk [536]

Answer:

<u>PCIe</u> is used for video card installation on Laptop.

Explanation:

Good quality applications, videos and games required graphics card for better results. These card can be installed on laptops, that required some ports.

PCI-e is a slot, that is used in laptop for video or graphic card interface. Video card or graphic card is used to enable high quality video or graphics on Laptop.

PCI- E stand for Peripheral Component Interconnect Express. It work as serial communication interface for high speed device.

Because filling a pool/pond with water requires much more water than normal usage, your local city charges a special rate of $0.
nevsk [136]

Answer:

In C:

#include <stdio.h>

int main(){

   float length, width, depth,poolvolume,watervolume,charges;

   printf("Length (feet) : ");    scanf("%f",&length);

   printf("Width (feet) : ");    scanf("%f",&width);

   printf("Depth (feet) : ");    scanf("%f",&depth);

   poolvolume = length * width* depth;

   watervolume = length * width* (12 * depth - 3)/12;

   charges = 100 + 0.77 * watervolume;

   printf("Invoice");

   printf("\nVolume of the pool: %.2f",poolvolume);

   printf("\nAmount of the water needed: %.2f",watervolume);

   printf("\nCost: $%.2f",charges);

   printf("\nLength: %.2f",length);

   printf("\nWidth: %.2f",width);

   printf("\nDepth: %.2f",depth);

   printf("\nMr. Royal [Replace with your name] ");

   return 0;}

Explanation:

This declares the pool dimensions, the pool volume, the water volume and the charges as float    

float length, width, depth,poolvolume,watervolume,charges;

This gets input for length

   printf("Length (feet) : ");    scanf("%f",&length);

This gets input for width

   printf("Width (feet) : ");    scanf("%f",&width);

This gets input for depth

   printf("Depth (feet) : ");    scanf("%f",&depth);

This calculates the pool volume

   poolvolume = length * width* depth;

This calculates the amount of water needed

   watervolume = length * width* (12 * depth - 3)/12;

This calculates the charges

   charges = 100 + 0.77 * watervolume;

This prints the heading Invoice

printf("Invoice");

This prints the volume of the pool

   printf("\nVolume of the pool: %.2f",poolvolume);

This prints the amount of water needed

   printf("\nAmount of the water needed: %.2f",watervolume);

This prints the total charges

   printf("\nCost: $%.2f",charges);

This prints the inputted length

   printf("\nLength: %.2f",length);

This prints the inputted width

   printf("\nWidth: %.2f",width);

This prints the inputted depth

   printf("\nDepth: %.2f",depth);

This prints the name of the programmer

   printf("\nMr. Royal [Replace with your name] ");

   return 0;}

Consider a pipelined than can issue up to one instruction per cycle, but fewer may be issued because of pipeline hazards, multi-
a_sh-v [17]

Answer:

Achieved Instruction per cycle rate is 4.11\times 10^{15}

Solution:

As per the question:

Execution time, t = 1.4 s

No. of instructions being executed, n = 1.8 billion =

Clock speed of CPU, f = 3.2 GHz = 3.2\times 10^{9} Hz

Now, to calculate the actual issue rate achieved:

CPI (Cycle per Instruction) = \frac{t}{n\times f}

CPI = \frac{1.4}{1.8\times 10^{6}\times 3.2\times 10^{9}}

Instruction per cycle is given as the reciprocal of CPI:

Instruction per cycle = \frac{1.8\times 10^{6}\times 3.2\times 10^{9}}{1.4} = 4.11\times 10^{15}

A town government is desinging anew bus system
Kamila [148]

Answer:

Umm what? Are you talking about the type of problem it is? If so it is an optimization problem.

Explanation:

I had something like this for one of my tests and I chose the optimization problem because it finds the values of decision variables that result in a maximum or minimum of a function.

But ion know if it's this that you are talking about
