Explain how Steve Jobs created and introduced the iPhone and iPad.

1 answer:

8 0

Answer:Today, we're introducing three revolutionary products. The first one is a widescreen iPod with touch controls. The second is a revolutionary mobile phone. And the third is a breakthrough Internet communications device. So, three things: a widescreen iPod with touch controls, a revolutionary mobile phone, and a breakthrough Internet communications device. An iPod, a phone, and an Internet communicator. An iPod, a phone...are you getting it? These are not three separate devices. This is one device. And we are calling it iPhone. Today, Apple is going to reinvent the phone.

Late last year, former Apple engineer Andy Grignon, who was in charge of the radios on the original iPhone, gave behind-the-scenes look at how Apple patched together demos for the introduction, with Steve Jobs showing off developmental devices full of buggy software and hardware issues. The iPhone team knew that everything had to go just right for the live iPhone demos to succeed, and they did, turning the smartphone industry on its head even as Apple continue to scramble to finish work on the iPhone.

Apple had actually been interested first in developing a tablet known as "Safari Pad", but as noted by a number of sources including Steve Jobs himself, the company shifted gears once it became clear how revolutionary the multi-touch interface developed for the tablet could be for a smartphone. Apple's tablet wouldn't surface until the launch of the iPad in 2010, three years after the introduction of the iPhone.

Seven years after the famous Macworld 2007 keynote, the iPhone has seen significant enhancements in every area, but the original iPhone remains recognizable as Apple has maintained the overall look of a sleek design with a larger touchscreen and a single round home button on the face of the device.

The area of a square is stored in a double variable named area. Write an expression whose value is length of the diagonal of the

melisa1 [442]

Answer:

sqrt(area)

Explanation:

Here sqrt is a short form of square root.
area is a variable name having he area of square.
When the function is called, it will give the square root of the value stored in variable area.

As we have to find the length of the diagonal, we must knew that as all sides of the square are same in length so are the diagonals. This means that each of the four sides of the square and it diagonals are equal in length.

So a square has: length=breadth=diagonal

As Area= length*breadth

√area = length (as length = diagonal length)

So √area = diagonal length

The OSI model is a useful tool in troubleshooting a network because it enables you to isolate a problem to a particular software

lutik1710 [3]

Answer:

1) Layer 4, transport

2) Layer 2, datalink

3) Layer 5, session

4) Layer 7, application

Description of Problems are as below:

1) One of your servers has been exhibiting sluggish network performance. you use a network-monitoring program to try to evaluate the problem. You find considerable TCP retries occurring because the server is being overwhelmed by data, and packets are being discarded.

2) You check some statistics generated by a network-monitoring program and discovers that an abnormally high number of CRC errors were detected. (Hint think of the cause of CRC errors).

3) A user is trying to connect to another computer, but the logon attempt is continually rejected.

4) You try to access a Linux server to share files by using NFS. You can communicate with the server, but the shared files don't appear to be available.

Explanation:

OSI Model is a reference model to determine how applications communicate over a network. OSI consists of seven layers, and each layer performs a particular network function. The seven layers are:

Layer 7 - Application.

Layer 6 - Presentation.

Layer 5 - Session.

Layer 4 - Transport.

Layer 3 - Network.

Layer 2 - Data Link.

Layer 1 - Physical.

Layer 4, transport

2) You check some statistics generated by a network-monitoring program and discovers that an abnormally high number of CRC errors were detected. (Hint think of the cause of CRC errors).

Layer 2, Data Link

3) A user is trying to connect to another computer, but the logon attempt is continually rejected.

Layer 5, session

4) You try to access a Linux server to share files by using NFS. You can communicate with the server, but the shared files don't appear to be available.

Layer 7, application

Consider the latency model for static congestion windows. If the server receives an acknowledgement for the first data segment i

Angelina_Jolie [31]

Answer:

Latency of an object O is shown below.

Explanation:

W segment and stalled state transmits nothing and waits for acknowledgement. The latency is 2 R TT + the time required for server that are using to transmit the object + the amount of time when server is in stalled state. Let K be the number of window that is K= O/WS .The serveries stalled state where K-1 is period of ime with period lasting RTT-(W-1)S/R

latency = 2RTT +O/R +(K-1)[S/R +RTT - WS/R]

After combining the two case

latency = 2 RTT + O/R + (K-1)[S/R +RTT - WS/R]

where [x] means maximum of (x.0). This is the complete ananlysis of the static windows.

server time for transmit the object is (K-1)[S/R +RTT - WS/R]

What is distribution hardware?

saveliy_v [14]

A distributed computer system consists of multiple software components that are on multiple computers, but run as a single system. The computers that are in a distributed system can be physically close together and connected by a local network, or they can be geographically distant and connected by a wide area network.
