What is it called when RAID appears to be hardware-based, but is actually software-based?

What is it called when RAID appears to be hardware-based, but is actually software-based?

• FakeRAID
• HS-RAID
• FalseRAID
• Triple Parity RAID          

EXPLANATION

FakeRAID is the industry term for software RAID that appears to be hardware RAID. This type of RAID is common in desktops.

What is Fake RAID?

So-called Fake RAID is a name commonly applied to motherboard / BIOS RAID features that provide the bare minimum for RAID functionality as it is understood. Low-end RAID cards get lumped in to this category because they may not offer the same DRAM cache and power loss protection features found in their more expensive counterparts. Why do low end RAID cards exist? They are mostly used to boot multiple operating systems from one array of hard drives.

In the early days of the Internet and Microsoft Windows 3.11, what were two components that needed to be installed before Windows could access the Internet using TCP/IP?

In the early days of the Internet and Microsoft Windows 3.11, what were two components that needed to be installed before Windows could access the Internet using TCP/IP?

• 4Gb of RAM and a solid state disk drive.
• Win32s and Trumpet WinSock
• 16-bit TCP/IP stack and Internet Explorer 4.
• A lot of coffee and a new PC. 

EXPLANATION

If you are installing the Windows 3.x 16-bit version of Netscape Navigator, it requires the Microsoft Win32s software be installed first.
If you received a copy of Win32s on a N.E.O.Net Sign-up Kit disk, then insert Win32s Disk 1 - Setup into your system's floppy drive, run the Setup application as outlined on the disk label, and follow the instructions on-screen.

Windows 3.x also requires that you have a dialer/winsock application such as Trumpet. You may wish to install Trumpet prior to Netscape.

With Windows 3.1/3.11 being a 16 bit operating system, the Win32s allowed certain 32-bit applications to run on the host system.

Trumpet Winsock would act as the modem/network "dialer" to make the connection to your ISP.

Internet Explorer 4 was not released until 1997 for use with Windows 95 or Windows NT 4.0, both of these OS's were 32 bit and did not require Win32s or Trumpet Winsock.

 In Microsoft Remote Desktop Services, What is the correct command that should be executed before installing software onto a terminal server?

• change user /install
• set mode /install

EXPLANATION

To install an end-user application on an RD Session Host server, the RD Session Host server must first be switched into a special install mode called RD-Install to ensure that the application will be able to run in a multi-user environment. After your applications have been installed on your RD Session Host server, you must switch the server back into execution mode (RD-Execute) before users can remotely connect to your server. You can switch between the install and execute modes from the command line using these commands:
change user /install
change user /execute
