System Komputer ada 3 :
1. Hardware (Perangkat Keras)
Definisi : Perangkat yang secara fisik bisa di pegang.
Contoh:
Motherboard (mainboard)
RAM
Harddisk
FDD (Flash Disk Drive)
Monitor
Mouse
Keyboard, dll
2. Software
ada 2 : OS dan aplikasi
OS (Operating System) / Sistem Operasi
Contoh : Windows, Linux, FreeBSD
Windows : DOS, Windows 98, sampai saat ini Win 10
Linux : Debian, Ubuntu, CentOS, RedHAT, dll
Aplikasi : Pendukung
Ms Office, AutoCAD, Photoshop, dll
3. Brainware (manusia yang mengoperasikan komputernya)
- Operator komputer
- IT Support
- System Administrator
- Programmer, dll
Cara pengecekan IP Address :
1. Melalui Command Prompt
- Tekan Windows + R dan muncul kotak dialog RUN
- Di kotak dialog run ketik cmd
- akan muncul command prompt
- untuk cek ip address ketik ipconfig
misal :
ip address : 192.168.1.12
subnet-mask : 255.255.255.0
gateway : 192.168.1.1
2. melalui control panel
- masuk ke control panel
- pilih network dan internet
- pilih network and sharing center
- pilih interface yang di gunakan misalnya pakai wifi
- pilih details untuk cek ip
- pilih properties untuk setting
- pilih internet protocol version 4 (IPV4)
3. klik kanan adapter yang aktif di pojok kanan dan hampir seperti cara yang kedua diatas.

*Cara Cek Koneksi dari pc ke pc atau dari laptop ke laptop:*
1. Ping
contoh :
C:\Users\rumah-belajar.com>ping 192.168.1.14

Mengenal NSLOOKUP
Fungsinya untuk mengetahui ip server dari suatu domain tertentu atau kebalikannya.
Contoh :
C:\Users\rumah-belajar.com>nslookup detik.com
Server: UnKnown
Address: 192.168.1.1
Non-authoritative answer:
Name: detik.com
Addresses: 103.49.221.211
203.190.242.211
C:\Users\rumah-belajar.com>nslookup google.com
Server: UnKnown
Address: 192.168.1.1
Non-authoritative answer:
Name: google.com
Addresses: 2404:6800:4003:c03::66
