unlike modern integrated GPUs though this was a chip that was affixed to the motherboard instead of being built into the CPU itself a paradigm that we saw again starting in the mid-1990s as 3d GPUs like the s3 trio and the ati rage series appeared on motherboards obviating the need for a separate card for basic use though GPUs that were soldered onto motherboards began to disappear in favor of ones built into CPUs by the mid 2010 speaking of CPUs let's jump back again to 1989 when the first CPU socket with a vaguely modern look socket 1 appeared alongside Intel's wildly popular 486 processor while earlier designs involved soldering the CPU directly to the board or significant force on the part of the user to insert or remove them socket one had a simple mechanism based around a pin grid array very similar to modern AMD sockets though with a mere 169 pins but it wasn't just CPU sockets that were getting a facelift expansion slots were also changing at that time and it was about time as the ancient is a standard had been used since the days of the original IBM PC in 1994 PCI started becoming popular in consumer pcs followed by the short-lived AGP for graphics cards in 1997 and PCI Express which is still with us today in 2004 but what about onboard networking in audio well in the mid 1980s there were a number of proprietary networking protocols but since the now-familiar Ethernet was a relatively simple standard with easy physical construction it became the go-to for networking in the late 80s and again its simplicity meant that it quickly spread to PC motherboards in the early 1990s and although sound cards also started appearing on the market in the late 80s and early 90s and we had little internal speakers that could emit beeps and bleeps for a while we didn't see true fully functional onboard digital sound hit the mainstream until 1999 when Intel included the AC 97 standard in its 810 chipset which incidentally was also the first Intel chipset to include integrated graphics meaning it was no longer necessary to have a separate chip for video processing be it on the motherboard or on an adapter card so now that all of these innovations had a clear home on the PC motherboard the stage was set for refinements made possible by decreasing costs and the continued miniaturization of components not to mention an increase in processing capacity to handle lots of different features meaning that these days even small form-factor motherboards feature RGB headers premium power delivery and Wi-Fi and of course by lear the 2010 manufacturers also realized that all those bells and whistles are meaningless without some vaguely threatening heatsinks to show all comers that you mean business speaking of meaning business do you mean business when it comes to keeping prying eyes away from your online activity then check out private Internet access VPN not only does P ia work on up to five devices at once hiding your true IP address it allows you to bypass to your restrictions and censorship by making you appear as though you are connecting from somewhere else and it's got all kinds of other great functionality too it blocks unwanted connections to help prevent attacks it Auto blocks all traffic if the VPN disconnects it keeps your data out of the hands of advertisers and other snoops who are tracking your activity it prevents DNS leaks and even includes mace P is built-in malware blocker it supports multiple VPN protocols and they've got apps for Windows Mac Android iOS Linux and even a Chrome extension with support for more platforms coming soon P ia has over 3,000 servers in 28 countries and doesn't log user activity so what are you waiting for check them out today at the link below so thanks for watching guys you can just like like you can check out other channels you can leave a comment if you have a suggestion for a future fast as possible and you can subscribe so you don't miss any videos here on tech Ricky over there I don't where the button is
