Hard Drive-less Computer

Every computer has a brain called the Central Processing Unit. It is named so because all major processes happen here. All brains have memory storage. And under the memory is the ROM or the Read Only Memory, the RAM or the Random Access Memory, and the cache. Among these storage hardware is the HDD or the Hard Disk Drive.

 

Most computers you see on the market today whether desktops or laptops have a hard disk drive or hard drive in short, as the main storage memory. There are those that have SSDs Solid State Drive as well. Hard drives have been proven a reliable technology in the computing world that’s why they are still around today and are ever-improving. A computer cannot efficiently process things without a memory hardware. But it can do so without a hard drive. Really? Arguably so.

 

A computer can still function without a hard drive. This can be done through a network, USB, CD, or DVD. Believe it or not.

Although a hard drive is typically where an operating system is installed, there are a number of ways you can run a computer without one. Computers can be booted over a network, through a USB drive, or even off of a CD or DVD. When you attempt to run a computer without a hard drive, you will often be asked for a boot device.

Upon startup. When a computer starts, various tests and checks are done. This is why you can’t immediately use the computer as soon as you see the desktop or the screen. You have to give it a minute or two.

When a computer first runs, a Power On Self Test (POST) is performed. This checks all of the hardware to make sure that everything is responding properly, then a series of system beeps are performed. The BIOS is loaded and the computer then looks for a boot device based upon the order of the devices in memory. These devices can be hard drives, network drives, external drives, or even removable media. Many servers are actual ran off of a single-network device with the hardware loading

Other Things To Consider When Buying A Mouse

You’ve done your research. You knew what you are looking for based on what you’ll use the mouse for. You’ve decided between a wireless mouse or a wired one. You’ve considered the dimension and the size. And of course, you’ve chosen the right shape and color for you (or maybe overlooked them because you decided they’re the last things to worry about). So now you might ask, can I proceed to the counter now? You can. If those are the only things you want to cover. Wait, there’s more? Yes. More specific criteria that is.

 

Mouse, like other parts of your computer, is still a machine. It has its technical and mechanical aspects. And if you are more on the picky side, then you might appreciate this article.

 

Sensors. The sensor type will depend on the manufacturer of the mouse.

From Razer’s “Dual Sensors” to Microsoft’s “BlueTrack” and Logitech’s “Darkfield,” advanced sensors offer a lot. On the gaming side of things, most companies offer calibration for different surfaces, insanely high DPI (covered later in this guide) and improved precision. And for the always-on-the-go office worker, some mice offer to work for you even on shiny surfaces like glass, marble and more.

The positioning of the sensors is also crucial. The sensors must be positioned in the center of the mouse.

The off-center sensor, however, resulted in extremely poor accuracy when making sharp flicks to the left or right.

Unless you are using your mouse for casual browsing only, do watch out for sensor placement. Look for a photo of the bottom of the mouse before your purchase. If the sensor is positioned too far from the center of the mouse – stay away!

Buttons. The different types and placements are vital as well. Again, it comes down to what you’ll use the mouse for.

Depending on how you use your mouse, you may need to consider the types of buttons and switches used. For late night web surfing or a busy office, you may want to consider a silent mouse. But for gaming or anything else where you really want
