Question

Why are algorithms considered essential to the way computers process information? One of friends, Jessica, is arriving at the airport and needs to get to your house. Create three algorithms that would help her get to the correct address. Submit a report that briefly discusses the following types of RAM: DRAM (dynamic random access memory) FPM DRAM (fast page mode dynamic random access memory) EDO DRAM (extended data-out dynamic random access memory) SDRAM (synchronous dynamic random access memory) DDR SDRAM (double data rate synchronous dynamic RAM) RDRAM (rambus dynamic random access memory)

Explanation / Answer

Ans 1 - To make computer perform a job , you have to write a program. Now, for writing a computer program, you have to tell computer in a proper manner, what you want it to do. Now, the computer will execute the program written by in a programming language. The execution will be done step by step to reach the goal.

The question is how the computer is going to achieve the goal. It will use various computer algorithms to get the job done.

Ans-2 The first algorithm to solve the problem is-

A) Book a Cab

You will tell your friend to book a cab with your address in the destination field of the application.

Steps:

a) Book a cab using any cab booking mobile application (like UBER).

b) Enter the given address in the destination field.

c) When cab arrives, enter into cab.

The second algorithm is :

B) Call my friend

a) When you arrive at airport, call my friend.

b) He will pick you from the Airport and leave you at my place.

The third algorithm is-

C) Get a Bus

a) Get into bus number 14 from the near bus stand outisde the Airport.

b) Bus will drop you near my location.

c) Walk from there using Google Map to my house.

All the above algorithms help you achieve the same goal, but each algorithm does it in a different manner.

Some algorithms does it less steps and other take more steps.

In booking a cab, you will need to spend more money while in catching a bus algorithm will cost you less money.

Ans 3- a) DRAM

b) FPM DRAM

c) EDO DRAM

d) SDRAM

e) DDR SDRAM

e) RDRAM
