Who invented apple electronics?
Apple was established on April 1, 1976 by Steve Jobs, Steve Wozniak, and Ronald Wayne,[1] to sell the Apple I personal computer kit. They were hand-built by Wozniak[22][23] and first shown to the public at the Homebrew Computer Club.[24] The Apple I was sold as amotherboard (with CPU, RAM, and basic textual-video chips)-less than what is today considered a complete personal computer.[25] The Apple I went on sale in July 1976 and was market-priced at $666.66 ($2,723 in 2012 dollars, adjusted for inflation.)[26][27][28][29][30][31] The Apple I, Apple's first product, was sold as an assembled circuit board and lacked basic features such as a keyboard, monitor, and case. The owner of this unit added a keyboard and a wooden case. Apple was incorporated January 3, 1977[6] without Wayne, who sold his share of the company back to Jobs and Wozniak for $800. Multi-millionaire Mike Markkula provided essential business expertise and funding of $250,000 during the incorporation of Apple.[32][33] The Apple II was introduced on April 16, 1977 at the first West Coast Computer Faire. It differed from its major rivals, the TRS-80 and Commodore PET, because it came with character cell based color graphics and an open architecture. While early models used ordinary cassette tapes as storage devices, they were superseded by the introduction of a 5 1/4 inch floppy disk drive and interface, the Disk II.[34] The Apple II was chosen to be the desktop platform for the first "killer app" of the business world-the VisiCalc spreadsheet program.[35] VisiCalc created a business market for the Apple II, and gave home users an additional reason to buy an Apple II-compatibility with the office.[35] According to Brian Bagnall, Apple exaggerated its sales figures and was a distant third place to Commodore and Tandy until VisiCalc came along.[36][37]
Are any of the computer parts co-dependent on each other for example does a specific graphics card require a specific motherboard or the other way around?
CPU > Motherboard > RAM > I/O (Graphics, Sound, Hard drive Controller, etc. ) Generally, one chooses a CPU, then based on the CPU requirements, amotherboard then RAM and so on. However if you are looking to use a specific graphics card, you would need to find the requirements for that model. The interface needs to match or be compatible, such as PCI express. If your video card uses a PCIx16 2.0 slot, your motherboard would need to be able to support a PCIx16 2.0 card. But if your board had a PCIx16 2.1 slot, it would still work because the 2.1 revision is backwards compatible. However, cards such as a PCIx1 slot is not compatible with a PCIx16 card. There are also motherboards that support SLI orCrossfire X This is a special link that allows to or more video card to work together. Some motherboards support SLI some supportCrossfire X some support both. AMD/ATI usesCrossfire Xto link their video cards, nVidia uses SLI. These are not cross compatible, i.e. SLI between an AMD card and nVidia card. All in all, graphics cards do not require a specific motherboard, nor do motherboards require specific video cards. Also, if the motherboard has the option for SLI, and only one graphics card is used, an AMD card will usually work just fine (Crossfire Xrequires 2 or more cards) and vice versa. One more exception is the new AMD APUs. These are processors with a GPU [Graphics Processing Unit] built in (notexactly but for simplicity we'll call it a GPU). These do have requirements for specific graphics cards if the added APUbenefitis to be utilized. Not required to function, just to utilize thebenefits.To sum it up, most of the time there are no specificdependenciesother that it fits in the slot provided (AGP had different voltage tabs that required them to match however PCI = PCI, PCIx1 will fit in a PCIx[1,2,4,6,8,16] slot. One more thing to consider, nowadays they have boards with PCIx8 - mechanically x16. this means the physical slot is a x16 slot, but it acts like an 8x slot (it only has the data throughput of an x8 slot) so a x16 would fit and work butwouldn'tgo as fast. You generally see this on moterboards with multi PCIx slots. So a board might has 4 PCIx slots, (x16, x8, x4, x4) so the first slot logically would have a 16x data bus, the second logical slot would have a 8x data bus, and the last 2 would run at x4. I hope this doesn't overwhelm you, its is a bit much for such a simple question. :) anyway hope it helps!
