Computer System Unit Components
Here are some :
Motherboard - a printed circuit board containing the principal components of a computer or other devices.
Power Box- electronic device that supplies electric energy to an electrical load.
RAM- "Random Access Memory"
Processor
Hard Disk
SATA Cables
Fan
ETC...

Basic Computer Hardware Troubleshooting
First, the very IMPORTANT thing.....
CHECK THE POWER SUPPLY.. !!
Then, make sure that all hardware are properly connected.
Reboot your computer.
Check the device manager.
Check if all devices or hardware are not broken or damaged.
Test the electrical outlet.
You must do this on some errors like THE BLUE SCREEN OF DEATH ..

Computer Generations
There are 5 :
1st Generation – Vacuum Tubes
2nd Generation – Transistor
3rd Generation – Integrated Circuit
4th Generation – Microprocessor
5th Generation – AI or Artificial Intelligence.

Machine Cycle
It is also called processor cycle. It is the basic operation performed by the main logic unit of the computer which is the CPU.
The machine cycle has 3 steps :
1. Fetch
2. Decode
3. Execute
There is another step which is "Store".
Networking
Network - is a group of two or more computer systems linked together.
Packet - is the unit of data that is routed on a network.
There are different types of network :
Some are WAN, MAN, LAN, WLAN ,etc.
In data representation, data are represented as electromagnetic signals such as an electrical voltage, radiowave, etc.

Conversion
Actually, conversion on BIN/DEC/HEX.
BINARY – DECIMAL [Positional Notation]
DECIMAL – BINARY [Division by Two with Remainder]
BINARY- HEXADECIMAL [4 bits = 1 hex digit]
HEXADECIMAL – BINARY [1 hex digit = 4 bits]
DECIMAL – HEXADECIMAL [Dec-Bin-Hex][ /16 ]
HEXADECIMAL – DECIMAL [Hex-Bin-Dec] [Place Values]

Binary
Binary means "composed of two parts".
A binary number is a representation for numbers using only two digits (0 and 1)
It is also called "base-2"
