History of the Intel Cpus and Pcs

Steven Michael Stepien TB143 Week 2 6/25/2011 HISTORY OF INTEL CPUs USED IN PCs That was the year Intel created the 8086, a 3-micron detach chugging along at 4.77MHz, succession later on versions would run at up to 10MHz. The 8086 had just 29,000 transistors, which was dumb nearly four clock as many as the 8085 released in 1976, and was Intels send-off 16-bit microprocessor and amenable for kicking off the 16-bit period (note that the 8086 wasnt the first 16-bit knap). Backwards compatibility with package written for the 8008, 8080, and 8085, and the ability to take aim 1MB of memory natively made the 8086 a near instant success. Intel arrest the computing world with the 80286 in 1982, a 1.5-micron part with a mind-boggling 134,000 transistors and 16MB of addressable memory. The first 286 pedaled along at 6MHz and, resembling the maestro 8086, would later replicate in speed. However, clock for clock, the 286 boasted in deuce ways (or more than) the performance of the 8086, a generational leap in the x86 architecture that has never been duplicated to this day. passim the decade, the 286 became synonymous with IBM PCs, and within 6 days of its release, Intel estimates there were 15 million 286-based PCs installed worldwide.

The 386, which was later named 386DX to keep down discombobulation with a demoralise cost 386SX variant that would institution trine years aft(prenominal) launch, initially ran at 16MHz and, at one time again, would in conclusion double in speed to 33MHz. It withal doubled the consequence of transistors from its antecedent to 275,000 and was Intels first 32-bit processor. The 386 could address up to 4GB (not MB) of memory, could switch amidst defend trend and real way, and added a ordinal virtual mode, which allowed the transaction of real mode applications that were unable to run in protected mode. Intel released one more x86 processor, the 486DX. The first CPU to overwhelm a built-in maths co-processor, the 486 raced along at 25MHz (and later 50MHz) and was also the first chip to breach the 1...If you want to clear a full essay, instal it on our website: Ordercustompaper.com
