Steve Jobs started NeXT when he left Apple in 1985. NeXT initially made computers and developed software, Tim Berners-Lee used a NeXT computer when he was developing his ideas that would become the World Wide Web, but in 1993 NeXT stopped making computers and became a software company. They had developed the NeXTSTEP operating system and the OpenStep programming environment. By the mid 1990s Apple was looking for a replacement for their Mac OS which they had been developing since 1984 but was not particularly suited to the expanding needs of computer users and the increasing use of Internet. In 1996 Apple purchased NeXT for $429 million. This allowed them to use the NeXTSTEP operating system as the basis for their own Mac OS X which first appeared as a Server system in 1999 and in a consumer version in 2001. The purchase of NeXT also brought Steve Jobs back to Apple; initially as a consultant and becoming CEO in 2000.

WorldWideWeb was the world's first web browser and WYSIWYG (What you see is what you get) HTML editor. It was introduced on February 26, 1991, by Tim Berners-Lee, and ran on the NeXTSTEP platform. It was later renamed Nexus to avoid confusion with the World Wide Web. WorldWideWeb was the first program which used not only the common File Transfer Protocol but also the Hypertext Transfer Protocol, invented by Berners-Lee in 1989. At the time it was written, WorldWideWeb was the only way to view the Web.

The operating system used on Macintosh computers is written primarily by the programers at Apple. However they incorporate innovations from outside Apple such as 'Cover Flow' which were popular with Macintosh users. The original operating systems upon which the latest versions of the Apple operating system are based are 'NEXTSTEP/OPENSTEP.' and 'BSD,' which is a derivative of 'UNIX.'

The classic Mac OS was becoming outdated and was not ideally suited for use on computers constantly connected to the Internet as was becoming the trend by the mid 1990's. After exploring various options Apple Computer acquired Steve Jobs' NeXT company for $427 million, in February 1997, and used their NeXTSTEP Unix based operating system as the basis for Mac OS X which started to appear in 2000. The purchasing of Next also returned Steve Jobs to Apple.

When she looks and feels happy with what you are doing at the moment then you can judge whether its time.
To be on the safe side then its always best to ask her because if you do take the next step and shes not ready then you are in big trouble and it might damage (if not ruin) your relationship.
It depends on how far you are so far because with my gf i take another step each day i went from hugging, walking her home,asking her out, holding hands, normal kissing, holding her on the bus, french kissing, say i love you, kissing on the neck, placed hand on leg while kissing, then touching her umm...since it's wikianswer bottom while making out. it has came naturally for me so maybe it will for you, too. P.S. let the girl do stuff too that's how i knew i could take the nextstep I've only been going out with her for two weeks and this has all happened

A computer is a piece of hardware, so no computer can be similar to Mac OS X (a piece of software).
If you are inquiring what other operating systems are similar to Mac OS X:
NextStep - operating system released by Next. Next was purchased by Apple, and NextStep was used as the base for Mac OS X.
FreeBSD - most low-level utilities in Mac OS X were updated with ones from FreeBSD
If you are inquiring about what hardware platforms are similar to that of the Macintosh:
Generic PC - Intel Macs share the same processors, and most of the same buses and connectors, They differ mainly in the firmware: Macs use EFI, a firmware created by Intel. Most PCs use a BIOS, which maintains compatibility (and some design flaws) with the original IBM PC of 1981.
IBM POWER Workstations - Older PowerPC-based Macs share much of the same architecture with concurrent IBM workstations.
BeBox - A PowerPC computer released in the mid-90s, had a similar architecture to concurrent Macs.

No, but they were greatly stimulated by IFO"s Identifiable flying objects of the Armed Forces ( ICBM guidance mechanisms, for example) and space craft, satellites- and so on. Microlectronics really took off- with the coming of Space technology- Man made, not alien. Transistors, subminiature tubes ( preferred by the Russians for some reason) and integrated circuits all play a vital role.

In 1980, while an independent contractor at CERN (June � December 1980), Berners-Lee proposed a project based on the concept of hypertext, to facilitate sharing and updating information among researchers. With help from Robert Cailliau he built a prototype system named Enquire. After leaving CERN in 1980 to work at John Poole's Image Computer Systems Ltd, he returned in 1984 as a fellow. By 1989, CERN was the largest Internet node in Europe, and Berners-Lee saw an opportunity to marry hypertext and Internet. In his words, "I just had to take the hypertext idea and connect it to the TCP and DNS ideas and � ta-da! � the World Wide Web" [1]. He used similar ideas to those underlying the Enquire system to create the World Wide Web, for which he designed and built the first browser (called WorldWideWeb and developed on NeXTSTEP) and the first Web server simply called httpd (which was short for HyperText Transfer Protocol daemon). Tim wanted people to combine their information and knowledge without thinking about the problem of geographic distance.

In a standard queue data structure re-buffering problem occurs for each dequeue operation. To solve this problem by joining the front and rear ends of a queue to make the queue as a circular queue
Circular queue is a linear data structure. It follows FIFO principle.
- In circular queue the last node is connected back to the first node to make a circle.
- Circular linked list fallow the First In First Out principle
- Elements are added at the rear end and the elements are deleted at front end of the queue
- Both the front and the rear pointers points to the beginning of the array.
- It is also called as "Ring buffer".
- Items can inserted and deleted from a queue in O(1) time.
Circular Queue can be created in three ways they are
· Using single linked list
· Using double linked list
· Using arrays
Using single linked list:
It is an extension for the basic single linked list. In circular linked list Instead of storing a Null value in the last node of a single linked list, store the address of the 1st node (root) forms a circular linked list. Using circular linked list it is possible to directly traverse to the first node after reaching the last node.
The following figure shows circular single linked list:
Using double linked list
In double linked list the right side pointer points to the next node address or the address of first node and left side pointer points to the previous node address or the address of last node of a list. Hence the above list is known as circular double linked list.
The following figure shows Circular Double linked list :-
Algorithm for creating circular linked list :-
Step 1) start
Step 2) create anode with the following fields to store information and the address of the next node.
Structure node
begin
int info
pointer to structure node called next
end
Step 3) create a class called clist with the member variables of pointer to structure nodes called root, prev, next and the member functions create ( ) to create the circular linked list and display ( ) to display the circular linked list.
Step 4) create an object called 'C' of clist type
Step 5) call C. create ( ) member function
Step 6) call C. display ( ) member function
Step 7) stop
Algorithm for create ( ) function:-
Step 1) allocate the memory for newnode
newnode = new (node )
Step 2) newnode->next=newnode. // circular
Step 3) Repeat the steps from 4 to 5 until choice = 'n'
Step 4) if (root=NULL)
root = prev=newnode // prev is a running pointer which points last node of a list
else
newnode->next = root
prev->next = newnode
prev = newnode
Step 5) Read the choice
Step 6) return
Algorithm for display ( ) function :-
Step 1) start
Step 2) declare a variable of pointer to structure node called temp, assign root to temp
temp = root
Step 3) display temp->info
Step 4) temp = temp->next
Step 5) repeat the steps 6 until temp = root
Step 6) display temp info
Step 7) temp=temp->next
Step 8) return
Using array
In arrays the range of a subscript is 0 to n-1 where n is the maximum size. To make the array as a circular array by making the subscript 0 as the next address of the subscript n-1 by using the formula subscript = (subscript +1) % maximum size. In circular queue the front and rear pointer are updated by using the above formula.
The following figure shows circular array:
Algorithm for Enqueue operation using array
Step 1. start
Step 2. if (front == (rear+1)%max)
Print error "circular queue overflow "
Step 3. else
{ rear = (rear+1)%max
Q[rear] = element;
If (front == -1 ) f = 0;
}
Step 4. stop
Algorithm for Dequeue operation using array
Step 1. start
Step 2. if ((front == rear) && (rear == -1))
Print error "circular queue underflow "
Step 3. else
{ element = Q[front]
If (front == rear) front=rear = -1
Else
Front = (front + 1) % max
}
Step 4. stop

HTML (HyperText Mark-up Language), which is widely used for creating web pages on the internet. He also created the specifications for URLs and HTTP, and is credited with inventing the world-wide web (internet). HTML was first conceived in 1989 as an adaptation of hypertext, a computer language that had been in use since 1946. HTML beta versions became available in 1990, and the language was formally published in 1993.
As of January 2011, the current version is HTML5.

Apple's Macintosh project was started in the late 1970s by Jef Raskin who built up a team of Apple engineers and designers including George Crow, Chris Espinosa, Joanna Hoffman, Bruce Horn, Susan Kare, Andy Hertzfeld, Guy Kawasaki, Daniel Kottke, and Jerry Manock. Steve Jobs joined the Macintosh team in the early 1980's and Raskin left the team in 1981 due to personality conflicts between himself and Jobs.

22/09/2006: Tim Berners-Lee, who invented the World Wide Web together with Robert Cailliau, built the first working prototype in late 1990 and early 1991. That first prototype consisted of a web browser for the NeXTStep operating system. This first web browser, which was named "WorldWideWeb," had a graphical user interface and would be recognizable to most people today as a web browser. However, WorldWideWeb did not support graphics embedded in pages when it was first released.
You can learn more about the original "WorldWideWeb" browser from Tim Berners-Lee himself.
Since WorldWideWeb had a graphical user interface (GUI), it could be called a graphical web browser. However, it did not display web pages with graphics embedded in them That did not happen until the arrival of NCSA Mosaic 2.0.
The first graphical web browser to become truly popular and capture the imagination of the public was NCSA Mosaic. Developed by Marc Andreessen, Jamie Zawinski and others who later went on to create the Netscape browser, NCSA Mosaic was the first to be available for Microsoft Windows, the Macintosh, and the Unix X Window System, which made it possible to bring the web to the average user. The first version appeared in March 1993. The "inline images," such as the boutell.com logo at the top of this page, that are an integral part of almost every web page today were introduced by NCSA Mosaic 2.0, in January of 1994. Mosaic 2.0 also introduced forms.
Netscape is the browser that introduced most all of the remaining major features that define a web browser as we know it. The first version of Netscape appeared in October 1994 under the code name "Mozilla." Netscape 1.0's early beta versions introduced the "progressive rendering" of pages and images, meaning that the page begins to appear and the text can be read even before all of the text and/or images have been completely downloaded. Version 1.1, in March 1995, introduced HTML tables, which are now used in the vast majority of web pages to provide page layout. Version 2.0, in October 1995, introduced frames, Java applets, and JavaScript. Version 2.0 was the last version of Netscape to introduce a major feature of the web as we know it today; later versions improved reliability and stability and introduced features that did not catch on as standards for all browsers. In 1998, Netscape decided to release their browser source code as open source software, and the Mozilla project began.
Microsoft Internet Explorer is by far the most common web browser in use at the minute.

We use Artificial Intelligence, or, AI, for multiple reasons. If we can find out more of AI, we could make a machine that could help us better in science and benefit the world.
- Robots are still under development, and even though we have come close at times to a sufficiently working AI, it has yet to succeed, due to the sheer fact that we can learn over time, and do trial and error. Robots, in a sense, unless we create them that way, can not. They could either not learn from doing something like, if we pushed someone, they'll push him back, (if we did a robot-on-robot) but he won't learn to stop. That's the hardest part.
- We use AIs to better our knowledge. Think about N.A.S.A. We didn't have to go to the moon, or even send satellites out there. But we did. Many people disagree with N.A.S.A. and their actions. If they knew how much things actually is in relationship with N.A.S.A., perhaps their view would change. For example, without N.A.S.A., we wouldn't have been able to use a G.P.S. or cell phones. That's a bit off topic, though, who knows, AIs might lead us to an even greater invention!
