Expert Solution & Answer
Explanation of Solution
Importance of software dependability:
Software dependability is a measure of software’s availability, reliability, and its maintainability, and maintenance support performance and characteristics such as durability, safety and security.
A complex organization design that recognizes the interaction between technology and people and is not limited only to software is known as socio-technical system.
Software dependability is most important in socio-technical system because of the following reasons:
- Unreliable software is liable to be discarded by users: Users May not use the system if they don't trust it.
- System failure costs may be enormous: System failure may lead to a loss of business.
- Unreliable systems may cause information loss: An undependable system may damage its external environment.
- An undependable system may lose or damage valuable data.
- Unreliable systems are difficult to improve: The reputation of the company who produced the system may suffer.
- Inefficiency is predictable: Software that is unreliable can have hidden errors which can violate system and user data without warning and whose consequences are not immediately obvious and the system may be in a breach of laws of consumer protection.

The table includes columns about customer location such as city, state, and country. You want to retrieve the first 3 letters of each country name. You decide to use the SUBSTR function to retrieve the first 3 letters of each country name, and use the AS command to store the result in a new column called new_country. You write the SQL query below. Add a statement to your SQL query that will retrieve the first 3 letters of each country name and store the result in a new column as new_country.arrow_forward
- We are considering the RSA encryption scheme. The involved numbers are small, so the communication is insecure. Alice's public key (n,public_key) is (247,7). A code breaker manages to factories 247 = 13 x 19 Determine Alice's secret key. To solve the problem, you need not use the extended Euclid algorithm, but you may assume that her private key is one of the following numbers 31,35,55,59,77,89.arrow_forwardConsider the following Turing Machine (TM).
