Bending, twisting, or the overall age of the cable, or other stuff like that.
Answer:
The computer was born not for entertainment or email but out of a need to solve a serious number-crunching crisis. By 1880, the U.S. population had grown so large that it took more than seven years to tabulate the U.S. Census results.1937: J.V. Atanasoff, a professor of physics and mathematics at Iowa State University, attempts to build the first computer without gears, cams, belts or shafts.1943-1944: Two University of Pennsylvania professors, John Mauchly and J. Presper Eckert, build the Electronic Numerical Integrator and Calculator (ENIAC). Considered the grandfather of digital computers, it fills a 20-foot by 40-foot room and has 18,000 vacuum tubes.1985: Microsoft announces Windows, according to Encyclopedia Britannica. This was the company's response to Apple's GUI. Commodore unveils the Amiga 1000, which features advanced audio and video capabilities.2006: Apple introduces the MacBook Pro, its first Intel-based, dual-core mobile computer, as well as an Intel-based iMac. Nintendo's Wii game console hits the marke

Answer:
Encryption method security:-
- Encryption method representing each alphabetic character as an integer between 0 and 25.
- Now, apply RSA algorithm for each integer is not an efficient secure encryption method.
Explanation:
- Let consider alphabetic characters set {A, B... Z} .
- Each alphabetic character forms a set of message block values M={0,1,2...,25).
- From encryption method the corresponding cipher text block value C = {0e mod n,1e mod n, 2e mod n,..., 25e mod n}.
- Then, compute the cipher text with knowledge of Bob's public key;
- If the public key is generated, then possibility to decrypt the cipher text to plain text.
- The generated public key is easily calculated by everyone and security is lost.
- Therefore, the encryption method is not secure.
Encryption method is not secure, Most efficient attack against this method:-
- Now, compute the encryption message with the function Me mod n for all the possible values of M.
- This is the most efficient attack against the scheme in encryption method.
- Then, create a look-up table with cipher text as an index to the corresponding plain text as a value for appropriate location in the table.
