Commerce Server
An application program that runs on a server tier computer. A typical commerce server obtains product data from a database, manages items in users' shopping carts, and coordinates the checkout process.
Explanation:
Let the size of a large server be L, and
the size of a small server be S.
We are given two scenarios,
2L+4S = 64.............(1)
and
L+3S = 40...............(2)
We solve the equations as follows
2(2)-(1)
2L-2L +6S-4S = 2*40-64
2S = 16
so S=8 ..................(3), size of small server
substitute (3) in (2)
L+3(8) =40
L = 40-24 = 16..............size of large server
The answer to this question is a firewall. A Firewall is a network
security system that blocks and prevent unauthorized use or access of company’s
network. Firewall is also a program that screens and restricts viruses and other
users like hackers to reach the network through the internet.
A burn-in test is a test which is usually performed on a system or component by running it for a long time in order to bring out any errors or system failures etc.
While doing it on CPU the data must be backed up as any kind of error or failure may result in the loss of data, at time systems can be repaired to retrieve data but still there is no guarantee, backing up is the best option.
