What does 386 mean in COMPUTING
The Intel 80386 is a 32-bit microprocessor released by Intel in 1985. It was the first x86 processor to reach up to 16 megabytes of memory, and it represented the transition from large multitasking systems to more powerful personal computers. Before the release of the 80386, the 8086 and 8088 CPUs were used in PCs. The processor has been around for more than three decades and has become an important milestone in computing history. The abbreviation “386” is commonly used to refer to this particular processor, but let’s take a closer look at why that is, what it means, and why it has been so influential for so long.

Meaning & Role
The term "386" often refers to the Intel 80386 processor. This processor was able to process 32-bit instructions, compared with other earlier processors that used 16-bit instructions. This allowed for operations like multi-tasking that weren't possible before with earlier models of processors. As well as being incredibly powerful for its era, it wasn't very expensive which made it accessible even to businesses on tight budgets and helped propel the development of business software applications such as spreadsheet software and database programs that could run on this platform when they couldn't previously have done so on previous platforms. The legacy of this processor continues today with many modern operating systems still supporting some form of software compatible with the architecture of the old 386 chip. Despite being eclipsed by newer generations of processors, its importance shouldn't be overlooked when considering developments in computing over the last three decades or so.
Essential Questions and Answers on Intel 80386 processor in "COMPUTING»COMPUTING"
What is a Intel 80386 processor?
The Intel 80386 processor, also known as the i386 or just 386, is the 32-bit microprocessor from Intel introduced in 1985. It was the first Intel processor to use a bit-manipulation instruction set and other features such as protected memory and virtual 8086 mode.
What types of operating systems can be used in an 80386 processor?
Operating systems that support the i386 architecture include Windows 3.1x, Windows 95/98/Me, OS/2, Linux and some versions of Unix. The original versions of these operating systems may no longer be supported by newer releases.
What are the advantages of using a Intel 80386 Processor?
The biggest advantage of using an intel 80386 processor is enhanced performance for certain types of computations such as floating point calculations. Additionally, it offers extended memory protection through segmentation and paging allowing multiple programs to run concurrently without interfering with each other's memory spaces.
How many transistors does an Intel 80386 Processor have?
An Intel i386 processor contains 275,000 transistors with a die size measuring 1.5 mm on a side.
What type of bus does an Intel 80386 require?
The i386 requires an AT bus with 8-bit data paths at 8 MHz or faster. This bus consists of 24 address lines with 16-bits for data and 8 bits for control signals.
How much power does an IBM compatible computer require if it utilizes an Intel 80386 processor?
A typical IBM compatible computer utilizing an i386 processor will require approximately 15 Watts per hour.
What are some common applications of an Intel 80386 Processor?
Common applications for this type of processor include personal computers, servers, embedded systems, scientific instruments, and aerospace applications such as satellites.
Does the I80 386 have any built-in security features?
Yes - the I80 386 has built in security features such as segmentation which allow multiple programs to run securely without accessing each other's address space. It also supports virtual 8086 mode which allows software to switch between different tasks while still protecting its own address space from interference.
Final Words:
In conclusion, “386” is shorthand for referring to Intel’s flagship 32-bit microprocessor from 1985 - The Intel 80386 CPU - which marked a key transition in computer engineering that allowed PCs themselves to become more powerful than ever before by taking advantage of multi-tasking capabilities not seen on previous models and pushing forward tech innovation through cost effectiveness thanks to its price point at launch. Its role in computing history remains largely overlooked but can’t be understated when thinking about how far technology has come since then until now - all thanks due largely due in part because of its architecture having supported modern operating systems over 3 decades later!
