Computer can still operate without which of the following

CPU, in turn, needs to lay down all the information it needs to process somewhere. It also requires a place to store the results of its work. That place is commonly known as random access memory or RAM. Without a CPU, a motherboard, and RAM, your computer is practically non-existing. Therefore, your computer does need RAM. RAM Is Essential for Your Computer Ever since computers appeared, they needed some sort of RAM to operate. Although there are theoretical ways to make a computer work without RAM, in practice, you wouldn’t have much use of such a construct at all. If you powered up a computer without RAM, it wouldn’t move past the POST screen (Power-On Self-Test). If you’ve experienced a faulty RAM module or a bad connection on the motherboard’s RAM slots, the corresponding error would appear on the screen. Several beeps coming out of your computer case would accompany it. This way, your computer would tell you that it lacks RAM and that it can’t boot up. As you use up your RAM, you might notice that your computer starts to slow down. That’s because a portion of your hard disk now stores parts of RAM’s registers, allowing it to keep up with the demand. The slowing of the system comes from the fact that your hard disk runs significantly slower than RAM. So to answer the question from the title, no, you can’t run a computer without RAM. Before 2000, when first DDR modules appeared (basically DDR1, although they’re called just DDR), computers used “Single Data Rate” (SDR) m...
