Answer:
Charles Babbage, (born December 26, 1791, London, England—died October 18, 1871, London), English mathematician and inventor who is credited with having conceived the first automatic digital computer.
Explanation:
The idea of mechanically calculating mathematical tables first came to Babbage in 1812 or 1813. Later he made a small calculator that could perform certain mathematical computations to eight decimals. Then in 1823 he obtained government support for the design of a projected machine, the Difference Engine, with a 20-decimal capacity. The Difference Engine was a digital device: it operated on discrete digits rather than smooth quantities, and the digits were decimal (0–9), represented by positions on toothed wheels rather than binary digits (“bits”). When one of the toothed wheels turned from nine to zero, it caused the next wheel to advance one position, carrying the digit. Like modern computers, the Difference Engine had storage—that is, a place where data could be held temporarily for later processing.
Answer:
A. One
Explanation:
Symmetric key cryptography makes use of one key. The same key is used for both encryption and decryption. This is different from asymmetric cryptography where separate keys are used for the two operations. Some examples of symmetric cryptography include:
- Advanced Encryption Standard (AES)
- Data Encryption Standard (DES)
- Triple Data Encryption Standard (3DES)

Answer:
The answer to this question is "perimeter".
Explanation:
In computer science, the firewall is used to provide a network security system that manages network traffic like incoming and outgoing signals. This traffics is based on predetermined security rules. The firewall typically installs a boundary between a trusted inner network and an untrusted outer network, such as the Internet. It is a software concept and Perimeter firewalls manage the flow of network traffic and host or organization's border the boundary that provides the first line of security against outer attacks and blocking access to inappropriate content from inside an organization.
