Answer:
The development of computers from the beginning to what we see now is called the computer generations. It is gradual advancement in the technology in the making of the computer.
Explanation:
The generation in computer technology can be defined as the development or the change in the technology in the computer as it was used. There were five generations of computer development. They were :
1. First Generation computers
In this generation, vacuum tubes was used in the circuits. It dated from 1946 to 1959.
2. Second Generation computers
These are transistors based computers. This generation ranges from 1959 to 1965.
3. Third Generation computers
This generation computers were Integrated circuit based. The generation stared in 1965 and ended in 1971.
4. Fourth Generation computers
The computers of this generation used VLSI microprocessor in the circuits. The period of the 4th generation computers are from 1971 to 1980.
5. Fifth Generation computers
The computers of this generation used ULSI microprocessor in the circuits. The 5th generation computers started from 1980s.
Answer:
Option C is the correct answer for the above question
Explanation:
Authentication is used to grant a person to use the system so that no other person can hack the data of the system. It is done by some unique id which is provided to the user of that system. When any person wants to use the system he needs to use that a unique id and sometimes password and some other information to use the system.
The above question asked about the process through which the user of the system grants access to use the system only. So the process is Authentication. hence Option C is correct because it states about the process Authentication while the other is not because--
- Option a states Credibility which is not the process to enter the system.
- Option b states Authorization which is used if the system gives access to the user, not the user can take on its own.
- Option d states Honesty which is not the process to enter the system.
Javascript can be executed i believe. but i just googled it,check it for yourself
Answer:
The statement to this question is "cout << fraction;".
Explanation:
In the given question it is declared, that a floating-point variable "fraction" is defined, which holds some value. To print this variable value in C++ program we use the print function, which is "cout". This function also used to print messages and values, in this question the print function uses the float variable "fraction", which prints variable value.
Answer:
Drive Wipe F is correct
Explanation:
Drives content is virtual so it wouldn't work to shred or incinerate it. overwriting it wouldn't work to get rid of files exactly. it might get rid of the files but it would replace the files with other files.
