Answer:
True
Explanation:
A Domain Name Service comprises of computer servers that carries a database of public IP addresses and their related human-readable domain names/hostnames, it receives query as hostnames and helps to translates those human-readable domain names/hostnames into IP addresses that computers and routers understand.
Answer:
The object oriented software engineering approach is basically focus on the attention for capture the given structure and conduct the data frameworks in the form of small module which consolidates the information and the procedure.
The principle and aim of the Object Oriented Design (OOD) is that improving the quality of the system analysis and increase its productivity and more usable efficiently.
There are different phases in the object oriented software engineering approach are as follows:
- Firstly, we start analyze and define the particular system
- Then, construct the analysis model based on the above approach of the specific system.
- We verify the correctness of the system by using the testing.
Answer:
Effort = 120 Newton
Explanation:
Given the following data;
Mechanical advantage = 6
Load = 780 N
To find the effort required to lift the weight;
Mechanical advantage can be defined as the ratio of the load (weight) lifted by a simple machine to the effort (force) applied.
Mathematically, the mechanical advantage is given by the formula;
Making effort the subject of formula;
Substituting into the formula, we have;
Effort = 120 Newton.
Answer:
d. RAID 6
Explanation:
Given: Your supervisor has asked you to configure a server with a RAID utilizing disk striping with two sets of parity bits for additional fault tolerance, so that up to two hard disk failures can occur without data loss.
The requirement can be accomplished using RAID 6 configuration which stands for Redundant Array of Independent Disks - Level 6.It makes use of 2 parity disks to handle two potential failures.
