What is a Computer anyway?
- According to the Definition, refers to all computing units which work on mechanical, electrical or electronic Basis, as a Computer.
- According to this Definition, every Computer doesn't say that every PC is a Computer but a PC.
- Because devices such as Smartphones, Tablets, or vending machines of all kinds can be referred to as a Computer.
- These devices can be programmed and process electronic data, which is why they are also referred to as a Computer.
- How exactly a Computer works, we can tell you in the next paragraph.

PC: So a Computer works
How does a Computer work? - The Components
Because a Computer is always structured in the same way, we consider the construction of a PC:
- Motherboard: This is the heart of the computer. On the Motherboard, all the important components of the PC are connected to each other and installed. Also the connections are on the Motherboard. Using the small data lines, data is forwarded and processed.
- BIOS: After you have switched on the Computer starts the BIOS, even before the actual System starts. In the BIOS, all components and components are tested. Once the examination is successfully completed, start the actual System.
- Processor: The processor can be considered as the brain of every computer. No matter what you do on the Computer, it is calculated in the processor. Also if you are running no programs running in the Background, the System and calculated.
- Graphics card: For gamblers can already see significant, because by using the graphics card, an optical output is made possible. Nowadays, the graphics card is already on the Motherboard, in this case, one speaks of a Onboard graphics card. To Run complex Games requires a external graphics card. It consists of a graphics processor and video memory.
- Memory: all processes on the Computer can be executed is required, the memory (RAM). The memory has a certain size. Too many actions are executed at once, it can happen that the memory is busy. This is due to slow Working of the computer is noticeable.
- Hard disk: the hard disk all the data that you have stored on the PC. Also, the operating system is on it. In the meantime, you can differentiate between SSD, so a so-called Solid State Drive, and a HDD, the Hard Disk Drive. If you have an SSD, you should install the operating system on these, so that the start-up process of the computer is faster. Also hard drives have a certain size and can eventually be full.
How does a Computer work? - Simply explained
- By Pressing the Start button on the Computer will be started. The BIOS checks the hardware components and starts after the check is successful, the operating system from the hard disk.
- If you need to enter a password or move the mouse, to be forwarded electronic pulses to the Motherboard and processed.
- These entries are forwarded to the processor and calculated. The respective measures will be re-routed by using pulses and the respective action is executed.
- You have for example written a document in Word, you will see this on your screen. But be careful: so Far, the data are only in memory. In the event of a power failure, all data would be gone.
- Therefore, you should save the document to disk so you can access it again later.
In the next practical tip we show you how to have two Computer connect to each other can.
