Routers, on the other hand, use embedded bootloaders. BIOS can also serve as a layer between the operating system and the hardware. Its main task is to boot the hardware, carry out the POST ( Power On Self Test), which basically checks the hardware is in perfect condition, and load the bootstrap ( boot manager) to upload the operating system into the memory. PCs first execute a part of the software known as BIOS ( Basic Input/Output System). Let’s take a closer look at how this bootware works in the different systems. Other examples of such systems are printers, GPS navigation systems or DVD players.īoth PCs and routers are computer systems equipped with bootware stored in a non-volatile memory (usually FLASH or EEPROM – Electrically Erasable Programmable Read -Only Memory) used to initialize hardware and boot the operating system. ![]() Well, it’s simply a computer system designed to carry out a limited number of tasks, meaning their hardware and software is far more specific than that of a PC. “ What is an embedded system?”, you may ask. While it’s true to say there are quite a few differences, they also have a series of characteristics in common.įirst of all, routers fall into the so-called embedded systems category. Many people believe they have completely different electronic systems, but this is not entirely accurate. ![]() How does a personal computer (PC) differ from a router?
