Answer:
i) The time taken for 1500 records = 15 seconds.
ii) The time taken for 1500 records = 50 seconds.
Explanation:
A is an O(n) algorithm.
An algorithm with O(n) efficiency is described as a linearly increasing algorithm, this mean that the rate at which the input increases is linear to the time needed to compute that algorithm with n inputs.
From the question, it is given that for 1000 records, the time required is: 10 seconds.
Algorithm time taken is O(n)
Hence,
1) For 1,500 records
=> 10/1000 = x/1500
=> 10x1500/1000 = x
x = 15 seconds
Thus, the time taken for 1500 records = 15 seconds.
2) For 5,000 records
=> 10/1000 = x/5000
=> 10x5000/1000 = x
x = 50 seconds
Thus, the time taken for 1500 records = 50 seconds.
The answer is the second answer Increasing the size of the wire.
Answer:
1. B
2. D
3. C
4. A
5. B
Explanation:
1. To check the integrity of your hard disk and fix various file system errors, the Windows utility which should be implemented is Check disk (Chkdsk). This utility is always used with the command line interface (CLI) with the command "chkdsk."
2. An event or action took place and it caused damage to data, hardware, software and processing capability of the computer. From the statement given, security risks are being described. Any event or action that is capable of causing a problem to a computer system is considered to be a security risk and should be prevented through the use of an appropriate utility software.
3. Virus is a software program that can infect, damage and disrupts the whole computer system.
4. To protect the whole computer system, the software utility which is needed is an Anti-virus.
5. To avoid losing valuable data to your computer, the most important thing to do is to regularly back-up your files.
Answer:
RADIUS
Explanation:
RADIUS is the networking protocol that is used for the purpose of authentication to access the network resources. The full form of RADIUS is Remote Authentication Dial In User Service. It is used by different organizations, which setup their own network that can be accessible through VPN, DSL or modems through different networks. The purpose of this protocol is to establish the security and authentication mechanism by organization itself.
So, If an administrator needs to set up an authentication server for users connecting to a network through a VPN, he should establsih the RADIUS based Server.
