POP3 dan IMAP

POP3 and IMAP are two different protocols (methods) used to access email.
Of the two, IMAP is the better option - and the recommended option - when you need to check your emails from multiple devices, such as a work laptop, a home computer, or a tablet, smartphone, or other mobile device. Tap into your synced (updated) account from any device with IMAP.

POP3 downloads email from a server to a single computer, then deletes it from the server. Because your messages get downloaded to a single computer or device and then deleted from the server, it can appear that mail is missing or disappearing from your Inbox if you try to check your mail from a different compu

What is safe mode?

Safe mode is a troubleshooting option for Windows that starts your computer in a limited state. Only the basic files and drivers necessary to run Windows are started. The words Safe Mode appear in the corners of your monitor to identify which Windows mode you're using.

If an existing problem doesn't reappear when you start in safe mode, you can eliminate the default settings and basic device drivers as possible causes. If you don't know the cause of the problem, you can use the process of elimination to help you find the problem. Try starting all of the programs you commonly use, including the programs in your Startup folder, one by one to see if a program might be the cause of the problem.

If your computer automatically starts in safe mode without prompting, a problem with your computer might be preventing Windows from starting normally. If you think the cause of the problem might be a recently installed program or device, try using Recovery in Control Panel.

Di Safe mode with networking:

• Bisa nonton youtube tapi tidak ada suara.
• Bisa intenetan, bisa ping ke local network.
• Bisa jalankan program Microsoft Word, Adobe Reader PDF.
• Bisa jalankan program network simulator seperti: GNS3, Cisco Packet Tracer 
• Tidak bisa menjalankan Fitur NTP.
• Tidak bisa menjalankan Operating System berbasis VMWare.

Cautions:

1. GNS3 bisa dijalankan pada mode "Safe Mode With Networking" Windows.
2. Idle PC bisa dihitung/dikalkulasi setelah perangkat di jalankan.
3. Config-nya bisa di save atau di-export. Asal tiap device/perangkat di assign command: copy run start terlebih dahulu.
