A user complains that her computer is performing slowly. She tells you the problem started about a week ago when new database software was installed. The software runs in the background to update a database synced between the user’s workstation and database server. Which is the best tool or method to use to determine if the new software is hogging computer resources? a. Uninstall the database software and see if performance improves. b. Use Performance Monitor and Process counters to observe performance. c. Use the Performance tab of Task Manager to observe database software activity. d. Install more memory to improve system resources to handle the new software.

Expert Solution & Answer

Explanation of Solution

Given:

A user installed a software to update the database synced in database servers and usersâ€™ workstation. After performing all these tasks, the usersâ€™ computer gets slowed down.

To find: The method/tool to solve the hogging problem caused due to the installation of new software.

Solution:

Open the Task Manager and check the application that is using maximum RAM and Disk Space.

This application is responsible for computer hogging. When one program needs all of the CPUâ€™s attention, other programs that also need the CPU might not get enough time to do their work.

Hence, c is the correct option.

2. Signed Integers Unsigned binary numbers work for natural numbers, but many calculations use negative numbers as well. To deal with this, a number of different methods have been used to represent signed numbers, but we will focus on two's complement, as it is the standard solution for representing signed integers. 2.1 Two's complement • Most significant bit has a negative value, all others are positive. So, the value of an n-digit -2 two's complement number can be written as: Σ2 2¹ di 2n-1 dn • Otherwise exactly the same as unsigned integers. i=0 - • A neat trick for flipping the sign of a two's complement number: flip all the bits (0 becomes 1, or 1 becomes 0) and then add 1 to the least significant bit. • Addition is exactly the same as with an unsigned number. 2.2 Exercises For questions 1-3, answer each one for the case of a two's complement number and an unsigned number, indicating if it cannot be answered with a specific representation. 1.

1. Unsigned Integers If we have an n-digit unsigned numeral dn-1d n-2...do in radix (or base) r, then the value of that numeral is n−1 r² di Σi=0 which is basically saying that instead of a 10's or 100's place we have an r's or r²'s place. For binary, decimal, and hex r equals 2, 10, and 16, respectively. Just a reminder that in order to write down a large number, we typically use the IEC or SI prefixing system: IEC: Ki = 210, Mi = 220, Gi = 230, Ti = 240, Pi = 250, Ei = 260, Zi = 270, Yi = 280; SI: K=103, M = 106, G = 109, T = 10¹², P = 1015, E = 10¹8, Z = 1021, Y = 1024. 1.1 Conversions a.
