Bezzdna [24]

Some computer engineering students decided to revise the LC-3 for their senior project.  KBSR and the DSR into one status register: the IOSR (the input/output status register). IOSR[15] is the keyboard device Ready bit and IOSR[14] is the display device Ready bit can be done in LC-3.

LC-4 is a poor design.

Explanation:

LC-3, is a type of computer educational programming language, an assembly language, which is a type of low-level programming language.

It features a relatively simple instruction set, but can be used to write moderately complex assembly programs, and is a theoretically viable target for a C compiler. The language is less complex than x86 assembly but has many features similar to those in more complex languages. These features make it useful for beginning instruction, so it is most often used to teach fundamentals of programming and computer architecture to computer science and computer engineering students.

The LC-3 specifies a word size of 16 bits for its registers and uses a 16-bit addressable memory with a 216-location address space. The register file contains eight registers, referred to by number as R0 through R7. All of the registers are general-purpose in that they may be freely used by any of the instructions that can write to the register file, but in some contexts (such as translating from C code to LC-3 assembly) some of the registers are used for special purposes.

When a character is typed:

  • Its ASCII code is placed in bits [7:0] of KBDR  (bits [15:8] are always zero)
  • The “ready bit” (KBSR[15]) is set to one
  • Keyboard is disabled -- any typed characters will be ignored

When KBDR is read:

  • KBSR[15] is set to zero
  • Keyboard is enabled
  • Alternative implementation: buffering keyboard input

Explain SATA peripheral bus operation?
grin007 [14]
Peripheral Bus is not associated with the SATA function on a computer as they are not universal to each other. If you can go more into context, that would be great.

When writing test methods, what functionality is verified by the system method "runAs()"?
olchik [2.2K]

Answer:

The main functionality verified by this test method command is user sharing record.

Explanation:

Generally, every apex code runs in system mode.

Apex is strong object-oriented programming language that allows the developers to execute flow and transaction control.

Using syntax which look like java and acts as databases, Apex allows the developer to add any type of business logics to an event which can include button, clicks records or visual pages.

Apex code can be initiated by web service request.  

The permissions and record sharing of current user are not consider by apex codes.

Now the system method runAs() will allow you to take or write a test method which will basically change the user context to an existing or an new user, so that the record sharing will take place.

runAs() command will not change or anything done with user permissions or permission levels, it will only record sharing of the user.  

When you use runAs() command the original and true context will run after the test method is once completed under the command of runAs().

The runAs() has no concern with the user license.  

If there is no or expired your personal or organization license you can just make a new user with this runAS() command.

In using this command we have to make a private class by the name of this test and then our further code to make a user , afterwards  which we will the true and original code of ours which we want to run.

There are many other uses of runAs() like  

 Mixed DML operations in test by opening the DML operations.

 We can also use it as a version which will take a package as a version argument. This will cause the code a specific version.

runAs(System.Version) is the command used for this.

Write only in C, not C++.
yawa3891 [41]

Answer:

#include <iostream>

using namespace std;

int main() {

  int k;

double d;

string s;

cin >> k >> d >> s;

cout << s << " " << d << " " << k << "\n" << k << " " << d << " " << s; }

                                                                   

Explanation:

k is int type variable that stores integer values.

d is double type variable that stores real number.

s is string type variable that stores word.

cin statement is used to take input from user. cin takes an integer, a real number and a word from user. The user first enters an integer value, then a real number and then a small word as input.

cout statement is used to display the output on the screen. cout displays the value of k, d and s which entered by user.

First the values of k, d and s are displayed in reverse order. This means the word is displayed first, then the real number and then the integer separated again by EXACTLY one space from each other. " " used to represent a single space.

Then next line \n is used to produce a new line.

So in the next line values of k, d and s are displayed in original order (the integer , the real, and the word), separated again by EXACTLY one space from each other.

The program along with the output is attached.

Which of the following statements is not true? Question 16 options: a) SQL is the most popular query language used for interacti
lisov135 [29]

Answer:

The answer to this question is option "d".

Explanation:

In this question option d (A user fills out a form to construct a description of the data desired in a SQL search) is not true. Because SQL stands for Structured Query Language. This is a query language used to communicate with a database and a user fills the form. Which is not possible in the SQL. So the option d is not true.
