Computer Fundamentals

The computer is termed computation. For calculating or computing something the device that has been used is known as the computer. Or we can say that for performing a fast arithmetic operation the device that has been used is a computer. Storing, processing, and retrieving are the main features of a computer.

10) We have another, more common name for doing manual static white box testing. What is it? (Hint: if it is manual, static, and white box, there is only one thing you can be doing...)
Using your favorite language and compiler, investigate the order of evaluation of subroutine parameters. Are they usually evaluated left-to-right or right-toleft? Are they ever evaluated in the other order? (Can you be sure?) Write a program in which the order makes a difference in the results of the computation.
In Python language, define a function that takes two parameters count and sum as the parameters and returns the average from the function. Also, make a call to the function for some sample test cases.
1. why is debugging with a storage dump the most ineffficient of the brute-force methods? A. It contains program actions between the time of the dump and the time of the error that can mask the clues needed to find the error. B. It shows the program state at all times for error detection and for studying program dynamics. C. it sets breakpoints that cause suspesion in the program so that the programmer can examine the current state of the program. D. It requires a change of the program and such changes can mask the error, alter critical timing relationships, or introduce new errors. 2. What is a best practice for bug tracking? A. A bug item note/entry is unnecessary for every failure found during testing. B. Bug tracking is the responsibility of QA rather than development. C. Bug tracking is required to manage analysis and resolution of issues found throughout the development process. D. Bug tracking is only required during the UAT phase of testing in order to document user…
PLEASE USE C PROGRAMMING TO CODE THIS PROBLEM. EXPLAIN the logic with us of a diagram if possible, or clear enough that i can write this code if I was to ever come across a problem like it again Description Given a board with N rows and M columns, the rows are numbered from 1 to N from top to bottom, and the columns are numbered from 1 to M from left to right. Each element has one diagonal wall which either runs from top-left corner to bottom-right corner, or runs from top-right corner to bottom-left corner. Now given Q queries, you have to output which column the ball will fall out at the bottom row if you put it on top of the board at specific column. (The ball will naturally fall down due to gravity.) The following figure is a sample. If you drop the ball at column 2, the ball will fall out at the left side. If you drop the ball at column 5, the ball will be stuck in the board. If you drop the ball at column 3, the ball will eventually fall out at column 2. Input First line…
A stopwatch has three states named Zero, Running, and Stopped. There are two buttons, named B1 and B2. For each button, pressing the button produces a 1 and not pressing the button produces a 0. B1 works as follows: If the stopwatch is in the Zero state, pressing B1 causes it to advance to the Running state. If the stopwatch is in the Running state, pressing B1 causes it to advance to the Stopped state. If the stopwatch is in the Stopped state, pressing B1 causes it to return to the Running state. Pressing B2 has no effect unless the stopwatch is in the Stopped state, in which case pressing B2 (even if B1 is pressed) causes the stopwatch to go to the Zero state. Design a finite state machine controller for this stopwatch that has two inputs (B1 and B2) and three outputs, one for each of the three states. The state of the controller uses two J-K flip-flops. a. Draw the State Diagram for the controller. b.Then, use the state mapping table below and your state diagram to complete the…

Write a JAVA program that determines the alert level for the COVID-19 based on the percentage of new cases out of PCR tests carried out as indicated in the following table: Percentage of New Cases < 2% Between 2% and 5% (inclusive) Between 5% and 8% (exclusive) 8% or above Alert Level Green Yellow Orange Red % of new cases = (number of new cases / number of PCR tests) x 100 The program should ask the user to input the number of new cases and the number of PCR tests that were carried out. The program should display the percentage of new cases and the alert level. Sample Input / Output Enter the number of new cases: 280 Enter the number of PCR tests: 12000 Percentage of new cases is 2.333333333333335% Alert Level is Yellow Note: Your answer should follow the given sample input / output.
