Researchers in China have found a way to make flexible computer memory using liquid metal. It could one day revolutionize the physical design of computer devices. Anyone who has handled either internal computer RAM or a flash memory device will know ... that bending them even slightly would not end well. That's partly because the electronics is housed on often-brittle plastics, but partly because those electronics need to be flat and inflexible themselves. In very simple terms, RAM uses flat, two-dimensional electronic grids. Each point where a horizontal and vertical line crosses is a cell that ... (view more)

A new, unofficial version of Windows 11 runs on older machines with extremely limited memory and storage. In practice, though, Tiny11 is more for enthusiasts than the average user. Officially Windows 11 needs at least 4GB of RAM and 64GB of hard ... drive space. The specs are a big increase from Windows 10 following several previous Windows editions where the minimum specs either increased slowly or remained steady. That prompted debate about what elements of Windows boost the memory and storage requirements and whether those elements are really necessary or desirable. Now a Romanian tech ... (view more)

A new form of computer memory could cut costs and storage space. "UltraRAM" would combine storage and memory on a single unit. Historically computers have always had to use separate units for memory (which is only needed temporarily) and file ... storage (which needs to be available until intentionally deleted or altered). As a rough analogy, file storage is like a filing cabinet, while memory is more like an in-tray, holding information to hand for quick access during the current task. Today many machines use flash memory for both RAM (the main memory on a PC) and solid state drives (a quicker ... (view more)

In regard to last week's article on the Spectre and Meltdown CPU exploits, which affects 100% of all computers made since 1995, user 'rep' had the following question to ask: " Dear Dennis, [Being that this is a hardware exploit], am I right in ... thinking that any passwords, etc, which are stored in the CPU's memory are lost when the computer is shut down? If so, could I simply shut off the computer and reload it every time I want to use Internet banking and would that keep me safe from these exploits? " My response: I posted my original response in the comments section of Friday's article, but ... (view more)

I have it plugged in to the wall power outlet, but it still doesn't work. What do I do now? " My ... response: This is a fairly common issue with laptops; oftentimes the laptop won't turn on even if it's plugged into the wall if it's been sitting for a while - in your case, a few weeks. Sometimes, however, something else has gone wrong, and parts of the laptop may be corrupt or not working, or the laptop may have died. I'll explain what you need to ... (view more)

Some possibilities include: the laptop motherboard or display may have died, or ... (view more)
