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.

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.

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
