To what bridge on the motherboard is the CPU connected?
To what bridge on the motherboard is the CPU connected?
- Southbridge
- Northbridge
- Eastbridge
- Westbridge
EXPLANATION
The Northbridge is one of two chips in the chipset architecture on a PC motherboard. The second chip is called Southbridge.
Northbridge
is connected directly to the CPU via the FSB (front-side bus) and is
responsible for tasks that require the highest performance. Also RAM
(and integrated graphics) is located on the Northbridge.
For more detailed information check the source.

The convergence of traditional audio-video systems and high-bandwidth, low latency networking is know as what?
The convergence of traditional audio-video systems and high-bandwidth, low latency networking is know as what?
- AV Over IP
- Mesh AV
- HD BASE-T
- AV Over Fiber
EXPLANATION
AV over IP uses existing or additional networking infrastructure to transport encoded AV streams from source to destination without requiring costly dedicated AV cabling and switching equipment.This permits organizations to leverage their existing equipment and cabling often without significant modification.

If I twist the pairs as close as I can to the tip of an Ethernet connector, what am I reducing?
If I twist the pairs as close as I can to the tip of an Ethernet connector, what am I reducing?
- Power Redundancy
- Electromagnetic Radiation
- Mold Buildup
- Heat Dissipation
EXPLANATION
Twisted pair cabling is a type of wiring in which two conductors of a single circuit are twisted together for the purposes of improving electromagnetic compatibility. Compared to a single conductor or an untwisted balanced pair, a twisted pair reduces electromagnetic radiation from the pair and cross-talk between neighboring pairs and improves rejection of external electromagnetic interference.SOURCE

What will happen to a VM in VMWare when utilizing a snapshot of that VM and wanting to increase the size of an attached Hard Disk?
- Drive will become corrupted after reverting to the snapshot
- You will not be able to change the Disk size until the snapshot is removed
- Drive will increase in size but will shrink when reverting to before the snapshot
- Drive will increase in size and maintain size after reverting to the snapshot
EXPLANATION
Expand a Virtual Hard Disk
You can add storage space to a virtual machine by expanding its virtual hard disk.
When you expand a virtual hard disk, the added space is not
immediately available to the virtual machine. To make the added space
available, you must use a disk management tool to increase the size of
the existing partition on the virtual hard disk to match the expanded
size.
The disk management tool that you use depends on the virtual machine guest operating system. Many operating systems, including Windows Vista, Windows 7, and some versions of Linux, provide built-in disk management tools that can resize partitions. Third-party disk management tools are also available, such as Symantec/Norton PartitionMagic, EASEUS Partition Master, Acronis Disk Director, and the open-source tool GParted.
When you expand the size of a virtual hard disk, the sizes of partitions and file systems are not affected.
As an alternative to expanding a virtual hard disk, you can add a new virtual hard disk to the virtual machine. See Add a New Virtual Hard Disk to a Virtual Machine.

Prerequisites
■
Power off the virtual machine.
■
Verify that the virtual disk is not mapped or mounted. You cannot expand a virtual disk while it is mapped or mounted.
■
Verify that the virtual machine has no snapshots.
■
Verify that the virtual machine is not a linked clone or the parent of a linked clone.
Procedure
1
Select the virtual machine and select VM > Settings.
2
On the Hardware tab, select the virtual hard disk to expand.
3
Select Utilities > Expand.
4
Set the new maximum size for the virtual disk.
5
Select Expand.
6
Click OK after the disk expansion process is complete.
What to do next
Use a disk management tool to increase the disk partition size to match the expanded virtual disk size.

I have a User named "tux", and i've added "tux" to "sudo" group by the command: sudo usermod tux -a -G wheel. What kind of Distro do i have ?
- Fedora
- Gentoo
- Ubuntu
- Arch
EXPLANATION
In Unix/Linux distributions, the command ‘usermod‘ is used to modify or change any attributes of a already created user account via command line. The command ‘usermod‘ is similar to that ‘useradd‘ or ‘adduser‘ but the login granted to an existing user.
