Gateway Protection Solutions (firewalls, IDS/IPS, and Web security gateways), security cannot be relaxed in terms of Intranet protection, especially the terminal security. The endpoint security mentioned here is a big category. In addition to anti-virus software, IT also needs to provide protection for data information in users' personal computers, and for the I
1. Three operating modes of 386 processorsGenerally, 80x86 (80386 and later generations of CPUs) can run in three modes: real mode, protection mode, and virtual 8086 mode. Real mode is the operating environment of the ancient MS-DOS. Win95 and later operating systems only use two modes: protection mode and virtual 8086 mode. The security mode is a diagnostic mode for windows. In this mode, the system only l

The biggest difference between the built-in hard disk storage mode and the external hard disk is that the former places the hard disk inside the vro, the latter is connected to the router through the external USB port of the router. Generally, the built-in hard disk has high reliability and is more beautiful, while the external hard disk is easy to access, the USB interface is plug-and-play, and is conducive to the heat dissipation of the router. Therefore, the two hard disk storage metho
In today's IT industry development process, software will take more and more time for humans, and software definition concepts will become increasingly popular. Currently, the most fashionable software definition terms include: Software Defined Network (SDN), software defined storage (SDS), and software defined data center (SDDC ), and then extend to the new concept: Software defines everything (sdx ).
