If the floating-point number representation on a certain system has a sign bit, a 3-bit exponent, and a 4-bit significand. What
vekshin1

Answer:

Normalization of storage is a typical method of storing the floating point number by shifting the decimal after the first figure of the number such as 1101.101 is normalized to 1.101101x23.

If the number that is in hovering point representation has 1 sign bit, 3-bit exponent with a 4-bit significant:

whenever the storage is normalized, then the biggest positive floating spot number in 2`s and the complement notation is 0.11112 x 23 = 111.12 =7.5

If the storage is returned to normal, then the minimum positive floating point number is 0.12 x 2-4 =0.000012 =1/32 = 0.03125.

Explanation:

Whenever the floating figure is keyed into the computer memory, then the first bit will be the sign bit, the next 8 bits are for exponent and 23 bits are used for storing significand. The array of exponents is from -127 to 128. While Exponent 127 stands for 0 and positive figures can be represented by values bigger than 127. The biggest floating point number will be represented as 0.111111.... 1111x 211111111

Briefly explain the benefits and consequences of technology. //PLEASE ANSWER//
Wittaler [7]

Answer:

advantages and disadvantages of technology

Explanation:

Advantages of technology

First, the evolution of technology is beneficial to humans for several reasons. At the medical level, technology can help treat more sick people and consequently save many lives and combat very harmful viruses and bacteria.

The invention of the computer was a very important point. Communication is thus enhanced, and companies can communicate more easily with foreign countries. Research is also simplified.

For companies, progress in implementing strategic technology trends is helping them save time and therefore, money. Exchanges are faster especially with the internet. Sales and purchases are now facilitated and possible worldwide. This allows businesses to buy raw materials with discounts or at reduced prices. Similarly, global tourism has grown.

Technology has also increased the productivity of almost every industry in the world. Thanks to technology, we can even pay with bitcoins instead of using banks. The digital coin has been such a game changing factor, that many realised that this is the right time to open a bitcoin demo account.

When observed more closely, new things are discovered every day. Let’s take for instance when radio waves were discovered, radio broadcasts followed suit almost immediately. The same applies to the television and electricity. If no one had discovered that electricity could be generated, then the entertainment industry wouldn’t be at it’s current stage of development.

Technology improves daily lives; allowing to move physical storage units to virtual storage banks and more. Scientists of the time are also able to send astronauts to the moon thanks to technology.

In the modern industrial world, machines carry out most of the agricultural and industrial work and as a result, workers produce much more goods than a century ago and work less. They have more time to exercise and work in safer environments.

Disadvantages and risks of technology

On the other hand, the evolution of modern technology has disadvantages, for example, dependence on new technology. Man no longer needs to think. Even if the calculator is a good invention, man no longer makes mental calculation and no longer works his memory. The decline of human capital implies an increase in unemployment. In some areas, devices can replace the human mind.

The use of technology certainly needs rule and new laws. For example internet use is an individual freedom. However, the invention of the atomic bomb cannot be an individual freedom. In fact, regulations are difficult to implement when these technologies are introduced – such as regulation surrounding the impending arrival of autonomous vehicles.

Finally, as most technological discoveries aim to reduce human effort, it would imply that more work is done by machines. This equates to less work for people: the human is becoming ever so obsolete by the day, as processes become automated and jobs are made redundant.

Why does a bus topology require a terminator? a) because otherwise it would be a ring network b) because otherwise the packets w
Maksim231197 [3]

Answer:

B)because otherwise the packets will bounce back and forth from end to end repeatedly

Explanation:

Bus topology can be regarded as a kind of topology for a Local Area Network, it is one that has it's nodes connected to a single cable(backbone) and any break in the so called backbone, there will be failure in the entire segment. However a Terminator is usually attached to the end-points of a bus network so that the signal is absorbed by the Terminator and as a result of this the signal will not reflect back down the line. If there is no Terminator there would be bouncing back and forth of packet in an endless loop.It should be noted that a bus topology require a terminator because otherwise the packets will bounce back and forth from end to end repeatedly

What is the method for removing a domain controller in windows server 2012 r2?
-Dominant- [34]
Basically, you're going to use the Remove Roles and Features wizard.  However, there's a few more commands you can log into your computer to remove the controller as well.  You can use the dcpromo.exe command, the adprep.exe command, and then you can also alter the domain controllers through ADD roles and features wizard.
