calculate the speed when given the amount of 1TB to be transfer in 5hrs.

Answers

Answer:

Data transfer rate is the speed that a certain amount of data is transferred over a given period of time. You might want to know the transfer rate if you’re downloading something online or transferring data from one source to another. First, convert your units so the file size and transfer speed are in either bits or bytes with the same prefix (kilo, mega, giga, or tera). Then, plug your numbers into the equation S = A ÷ T in which A is the amount of data and T is the transfer time to solve for S, the speed, or rate, of transfer. You can also determine the amount of data or the transfer time if you know one of the variables plus the speed of transfer.

8 - test

2 - untwist wire ends

4 - trim wires to size

7 - check

3 - arrange wires

5 - attach connector​

Explanation:

Step 1. Strip cable by inserting into the stripping tool. Rotate the cable in a smooth and even motion to create a clean cut and pull away towards the end of the wire to remove the sheathing.

Step 2. Untwist wire ends. Separate the twisted wires and straighten them out to easily sort in the right order.

Step 3. Arrange wires. Put the wires in the correct order so they can be properly crimped.

Step 4. Trim wires to size. Use the cutting section of the crimping tool to cut them into an even line.

Step 5. Attach connector. Insert the connector so that each of the small wires fits into the small grooves in the connector.

Step 6. Crimp. Insert the connector in the crimping tool. Squeeze the handles to crimp the connector and secure the wires.

Step 7. Check. Take the connector our of the tool and look at the pins to see that they're all pushed down.

Step 8. Test. Lightly tug at the connector to make sure it's attached to the cable.

Steve Jobs


Born
Feburary 24, 1955


Death
October 5, 20122


Steven Paul Jobs was an American inventor, designer and entrepreneur who was the co-founder, chief executive and chairman of
Apple Computer.

Apple's revolutionary products, which include the



  • iPod

  • iPhone

  • iPad


Apple Computer


In 1976, when Jobs was just 21, he and Wozniak started Apple Computer in the Jobs’ family garage. They funded their entrepreneurial
venture by Jobs selling his Volkswagen bus and Wozniak selling his beloved scientific calculator. Jobs and Wozniak are credited with
revolutionizing the computer industry with Apple by democratizing the technology and making machines smaller, cheaper, intuitive and
accessible to everyday consumers.


Wozniak conceived of a series of user-friendly personal computers, and — with Jobs in charge of marketing — Apple initially marketed
the computers for $666.66 each. The Apple I earned the corporation around $774,000. Three years after the release of Apple's second
model, the Apple II, the company's sales increased by 700 percent to $139 million.


In 1980, Apple Computer became a publicly-traded company, with a market value of $1.2 billion by the end of its very first day of
trading. Jobs looked to marketing expert John Sculley of Pepsi-Cola to take over the role of CEO for Apple.


The next several products from Apple suffered significant design flaws, however, resulting in recalls and consumer disappointment.
IBM suddenly surpassed Apple in sales, and Apple had to compete with an IBM/PC-dominated business world.


In 1984, Apple released the Macintosh, marketing the computer as a piece of a counterculture lifestyle: romantic, youthful,
creative. But despite positive sales and performance superior to IBM's PCs, the Macintosh was still not IBM-compatible.


Sculley believed Jobs was hurting Apple, and the company's executives began to phase him out. Not actually having had an
official title with the company he co-founded, Jobs was pushed into a more marginalized position and thus left Apple in 1985.

Answers

Answer:

Perfection: When you make a mistake, no one cares but you.

Even the most accomplished public speaker will make a mistake at some point. Just keep in mind that you’ll notice more than anyone in your audience. The most important thing you can do after making a mistake during a presentation is to keep going. Don’t stop and—unless the mistake was truly earth shattering—never apologize to the audience for a minor slip. Unless they are reading the speech during your delivery, the audience won’t know if you left out a word, said the wrong name, or skipped a page. Because “to err is human,” a mistake can work for you, because it allows you to connect with your audience. People don’t want to hear from someone who is “perfect;” they will relate much more easily to someone who is real.

Master the art of public speaking and crush your next presentation with one of our public speaking seminars, available online and in a classic classroom format.

Effective Executive Speaking

Take your public speaking to the next level! Speak, present and communicate with poise, power and persuasion.

Visualization: If you can see it, you can speak it.

Winners in all aspects of life have this in common: they practice visualization to achieve their goals. Sales people envision themselves closing the deal; executives picture themselves developing new ventures; athletes close their eyes and imagine themselves making that basket, hitting that home run, or breaking that record.

The same is true in public speaking. If you’ve read “10 Powerful Body Language Tips” then you know how anxiety can impact presentation skills. The best way to fight anxiety and to become a more comfortable speaker is to practice in the one place where no one else can see you—your mind. If you visualize on a consistent basis, you’ll prepare your mind for the prospect of speaking in public, and pretty soon you’ll conquer any feelings of anxiety.

Discipline: Practice makes perfectly good.

Your goal is not to be a perfect public speaker. There is no such thing. Your goal is to be an effective public speaker. Like anything else in life, it takes practice to improve those public speaking skills. We too often take communication for granted because we speak to people everyday. But when your prosperity is directly linked to how well you perform in front a group, you need to give the task the same attention as if you were a professional athlete. Remember, even world champion athletes practice every day. Try taking a class where you practice giving speeches.
