Answer:
The given statement is "False".
Explanation:
Mainframes computer are also known big iron computer basically Mainframe computer is used by the big organization when the organization needs to work in the high-level project. The mainframe has big data processing. It is highly used in critical applications such as ERP(Enterprise resource planning).
A mainframe computer is not a flexible computer also they are not potable .microcomputers, are more flexible computers we can easily work on the microcomputers.
So the given statement is False.
Answer:
EDVAC (Electronic Discrete Variable Automatic Computer) was the successor to ENIAC, was binary based, and used stored programs, and was also designed by Eckert and Mauchly, UNIVAC I (UNIVersal Automatic Computer I) was the first commercial computer. It was designed by the same two men who designed ENIAC and EDVAC.
Explanation:
Answer:
// This program is written in C++ programming language
// Comments are used for explanatory purpose
// Program starts here
#include <iostream>
#include <string>
using namespace std;
// Declare variables
int inputvar;
// Declare output variable as array
int outputvar[32];
// Set a counter for binary array
int i = 0;
while (inputvar > 0) {
// Divide inputvar by 2 and store remainder in outputvar
outputvar[i] = n % 2;
inputvar/=2;
i++; // increment i by 1
}
// End of division
// Prin resulting array in reverse order
for (int j = i - 1; j >= 0; j--) {
cout << outputvar[j];
}
return 0;
}
// End of Program
Answer:
a. Encryption.
b. Authentication.
c. Strong.
d. Rogue.
e. Insecure.
f. Hacking.
Explanation:
In Computer technology, authentication can be defined as the process of verifying the identity of an individual or electronic device. Authentication work based on the principle (framework) of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.
Basically, authentication ensures a user is truly who he or she claims to be, as well as confirm that an electronic device is valid through the process of verification.
Encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext. Once, an information or data has been encrypted it can only be accessed and deciphered by an authorized user.
Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.
Wireless networks have no clear boundaries, therefore securing communications requires strong encryption, authentication, and strong protocols. One of the most common wireless security threats is the presence of rogue access points (APs). Rogue points can be set up for the benign purpose of free wireless access or for malicious purposes, such as gaining access to confidential data. Using an insecure wireless hotspot, like so many found in public settings, leaves you vulnerable to become the victim of hacking.
Answer: quotation marks (")
Explanation:
Quotation marks are put around a text string within a query criteria so that the results of the specifications are limited. We should note that the criteria is defined as the conditions which the users can set inside the query in order for them to get the records that they want to return.
