Compare and discuss between electro mechanical and era of computer.

aivan3 [116]

Answer:

When vacuum tubes were invented in 1890, the electronic computer era started. Compared to prior electromechanical devices, these tubes were thousands of times quicker. The Attansoff-Berry Computer was its name (ABC computer). Instead of electromechanical relays, the ABC computer employed vacuum tubes (an electrical device). When vacuum tubes were invented in 1890, the electronic computer era started.

Explanation:

An electromechanics professional (as myself) had studied a number of general courses about electronics, electricity and mechanics, in order to deal with integrated systems such as industrial robots, wind turbines, 3D printers and even the elevators of your building. All these systems rely on digital controls (sensors, processors, actuators, display panels) but are not purely digital, as they involve movement of small and big objects, and the use of significant amounts of energy in different forms (electricity, hydraulic force, electro-magnetism, etc.)

While an electromechanics engineer can design, build, operate and maintain such complex systems, it might not be able to design their individual components, such as an LCD display, a jet turbine or a power transformer, which indeed require a specialized electronics, mechanics or electric engineer respectively, do to so.

On the other hand, the electronics professional lives in 2 dimensions, one is that of the objects that leash and manipulate the electrons to detect, process and transmit digital signals, using semi-conductors to obtain physical items like a transistor, a LED light and a computer CPU; another dimension is the logical and digital world of software, where the 1s and 0s already captured by the physical devices are effectively used to do things as command the elevators to come to the eight floor as well as to send and email.

So, in essence, electromechanics is a more general field dedicated to the integration of digital and physical systems, and electronics is a more focused field dedicated to manipulate electrons and give life to the digital world.

Users of a new network subnet have been complaining that logons and other services are taking much longer than they did before b

Crank

Answer:

d.

Explanation:

Based on the scenario being described within the question it can be said that you should create a new subnet and add the subnet to the site that maps to the physical location of the clients. This will shorten the time that the information will take to get to it's destination and therefore drastically cut down the time that these services will take. Making customers happier.

Is recursion ever required to solve a problem? What other approach can you use to solve a problem that is repetitive in nature?

Setler79 [48]

Answer:

No you can not tell that recursion is ever required to solve a problem.

Recursion is required when in the problem, the solution of the input depends on the solution of the subsets of the input.

Iteration is also another form of repetitive approach we follow to solve that kind of problems.

But the difference between recursion and iteration is :

In recursion we call the function repeatedly to return the result to next level.
In iteration certain bunch of instructions in a loop are executed until certain conditions met.

Explanation:

For example in the Fibonacci sequence problem, to find $f_{n}$ , we need to compute $f_{n-1}$ and $f_{n-2}$ before that.

In case of recursion we just call the method Fibonacci(n) repeatedly only changing the parameter Fibonacci(n-1), that calculates the value and return it.

Fibonacci(n)

1. if(n==0 or n==1)

2. return 1.

3.else

4. return( Fibonacci(n-1)+Fibonacci(n-1) )

But in case of iteration we run a loop for i=2 to n, within which we add the value of current $f_{i-1}$ and $f_{i-2}$ to find the value of $f_{i}$

Fibonacci(n)

1. if(n<=2)

2. result = 1

3. else

4. result1 =1 and result2=1.

5. { result = result1 +result2.

6. result1= result2.

7. result2 = result.

8. }

9. output result.
