One way that computer networks help to protect data is by backing up the data.
Computer networks are normally formatted to automatically back up all of the data that is stored on them. This protects the data in case of any type of computer system failure.
Answer:
Three (3)
Explanation:
Explanation of the three basic terms here - Knowledge consistency checker, hops and domain controller - will give a clearer answer and explanation to the question as follows;
<em>Domain controller</em> : is a server controller that gives access or controls to users on computer networks by first responding to their authentication requests and verifying those users. In other words, a domain controller is a network security manager.
<em>Hop</em> : A hop is simply the passage of data packets from one network to another. As a packet moves from its source to destination, it moves from router to router. The number of such routers that the packet passes through is called a hop.
<em>The Knowledge Consistency Checker (KCC)</em> : It is the job of the KCC to ensure that these domain controllers participate in the replication promptly and orderly. Replication means copying data from one location to another (within a network or among networks). The KCC ensures that the maximum number of hops permitted is does not exceed 3. i.e no domain controller is more than 3 hops from any other domain controller within a network.
Note: Replication is of two types - intrasite (among all domain controllers within a site) and intersite (among all domain controllers in different sites), and the KCC can manage both type of replication. Also, by default, at every 15 minutes interval, a domain controller generates a replication topology (a logical map that dictates the domain controllers that will replicate with each other).

Answer:
C. ground antennas
Explanation:
AKA Satellite Dishes That Communicate Just Like Direct Tv dish It is focused by a bowl-shaped parabolic dish onto a device in the center called a "feed horn", which channels the signal to a "low-noise block down converter" (LNB) which filters out unwanted interference, and sometimes converts it to yet another frequency before amplifying it and sending it to the satellite receiver
In a file extension, it tells what type of file it is and tells what compiler to run the code.
