Answer:
Option b. Choke point
Explanation:
In firewall, a choke point can be defined as a single point which allows all of the network traffic including incoming and outgoing to be funneled. As the passage of the whole traffic through the choke point regulates the flow as it focus monitoring and controls bandwidth consumption, provides authentication, control efforts like Internet firewalls.
The two devices in a computer that should be considered "black boxes," and should never be opened due to risks involving charged capacitors are MONITOR and POWER SUPPLY.
Explanation:
- Physical contact or close proximity to the open power supply caused a discharge from the capacitor that resulted in an electric shock. Capacitors can discharge current even when not energized because they hold a charge for some time after the power is turned off.
- To do harm to your body, the voltage across the capacitor's terminals must be high enough to cause a harmful effect on you. There are no hard rules for at what voltage things become harmful, but a common 'rule of thumb' is that DC up to 48 Volt is considered low voltage. So a capacitor charged to a voltage below 48 V is fairly safe.
- A charged capacitor can be very dangerous, so it's important that you avoid coming into contact with the terminals at all times.
Answer:
It is not valid
Explanation:
I'll assume the question relates to cell referencing in Microsoft Excel.
To reference a cell in Excel, we make use of the following steps:
- Write out the cell column name first
- Followed by the row number
7b implies that, the row number first, followed by the column name; this doesn't follow the naming convention of cells.
Hence, 7b is invalid.
Answer: Image compression is the technique which is responsible for the reduction in the size of the image according to the need of the video technology. Image compression is done because of the following reasons:-
- Makes more space for the storage and creates space.
- It also reduces the time that is used up for the uploading of the video through internet.
- Text, labels etc might also be needed to inserted along with the image .
