Operating Systems and Utilities

The SX had a 16-bit external data bus, and that made it possible to build cheap PC's.
X 86 instructions was utmost implemented by 80486, due to which it executed faster, in a more RISC (Reduced Instruction Set Computing)1 like manner. The 486 was also the first CPU with built-in L1 cache. The 486 working was twice as efficient and fast as 386 and with the same clock frequency.
486 was a multi user and multitasking operating system, which worked under several other operating systems like DOS, Windows 3.11 and Windows 95. New editions were released with higher clock frequencies and double-clocked processors named 80486 DX2. (Michael Karbo)
Intel Corporation's microprocessor released in 1993, was the first fifth generation CPU incorporating more than 3.1 million transistors, the 32-bit Pentium processor is a highly integrated semiconductor device that has an external bus width of 64 bits. The first release featured clock speeds of 60 and 66 megahertz (MHz) achieving a performance of over 100 Mips2. It is almost twice as fast as the Intel 486 DX2 Microprocessor.
This performance is largely due to the Pentium Processors superscalar3 Architecture. Its dual execution pipeline implementation utilizes advanced design techniques that enable it to transparently execute multiple instructions per clock cycle. ...Show more

Summary

The first PC's were 16-bit machines, which could only work with the text with the only ability to manage one program at a time. That means these machines were single user with single tasking operations.
Just after 8086, 8088 was introduced. The uniqueness of these processors was that the bus between the CPU and RAM of these processors was of 8 bits…
