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:
It is essential for the existence of a helicopter administration over all other users on the system.
Explanation:
A system account is a computer user account that is generated by an operating system (OS) during installation of the OS and that is utilized by the user in accordance to the parameters with which it has been designed and the purpose which it was created.
A System account is usually referred to as a privileged account because it comes with full control on one or more directories. A directory is simply a location for file storage on a computer. Full access or control includes the ability to:
- read directories
- write to directories
- make changes to and delete files, folder and subfolders.
- alter authorization settings for all files and subdirectories.
Besides control on the directory level, System Accounts which are also called Super Accounts which in addition to the above have permission to
- install and remove software applications
- update and or upgrade the computers operating system
- access directories and files which normal users cannot and should not.
System Accounts are therefore important for security reasons. They are configured to act as a supervisory account which can create, authorise and terminate other accounts and processes.
Some of their merits include the ability to:
- Oversee, audit, and completely control all other privileges.
- forestall cyber attacks on the system from internal users or insiders.
- Establish and provide evidence for compliance with regulatory codes
