Answer:
C. 2^16
Explanation:
In Computer Networking, there are five (5) classes of IP addresses, these include;
- Class A
- Class B
- Class C
- Class D
- Class E
The various classes of IP address are represented by the value of their first octet. The first octet value of Class B is 128-191 with a subnet mask of 16.
Hence, from the IP address 149.130.x.y where x and y are 8-bit numbers. The x and y equals 16-bit numbers.
Thus, 2^16 devices can connect to the Wellesley network before we run out of IP addresses.
Answer:
A bread board is prototyped (manufactured) in a way where it is less permanent than a pcb (printed circuit board) or an even more permanent pcba (printed circuit board assembly). Bread boards are typically the first step to creating a finished circuit because electronic components are easier to test and take apart when needed; design and investigation can be made effectively as no soldering connections are required. Whereas a circuit board is used for the further finished products because they don't have sockets like the bread board and so there is little room for error and mistakes.
Answer:
<u>Scalable database</u>
Explanation:
Good examples of a scalable database include; NoSQL database, MySQL, Microsoft SQL.
<em>Remember</em>, these databases are called scalable databases because they support memory expansion without a measurable performance decrease.
For example, if the management of a hotel notices that its 1 terabyte computer used to store its security videos is no longer adequate to meet the hotel's expansion, then decide to buy a newer server that can be integrated into the current system. We can say they just applied the concept of scalable databases.
