Is B$4 is an example of a relative cell reference?

If your organization hires a new employee, what would you do to create a user account in the Linux system and add the account to

Y_Kistochka [10]

Creating users:

We will use the useradd command to achieve this. Using that same command, you can create users who would log in or customers who would log in (in the case of creating a user for a software installation).

In its basic form, the command is as follows:

[Options] useradd username

Take this user olivia, for instance. Assuming that you had been to issue the command prompt:

olivia has become a user.

Users are added to the system without the need for a home directory and are unable to log on. It if we were using this rather than running the command without arguments?

sudo using useradd -m olivia

Using the command above, a new user would be created, including a home directory that corresponded to the username. That means that you might now see the name "olivia" in the directory "/home".

But what about the lockout concern that was raised earlier? Both these methods are possible. After creating the user, you can enter the following command:

Password for olivia is: sudo passwd olivia

You'll be requested to enter & verify your new password once you've completed the process. This unlocks the user profile, allowing them to log in.

This command might look like if you wanted to accomplish it in one go:

sudo useradd -m olivia -p PASSWORD

You should be using Passcodes as the login for the user olivia.

As soon as the user logs in, he or she can update their account password by using the password command to input their current password, and afterward entering/verifying their new one.

To create a user that has no personal account and cannot log in, execute the following instructions:

sudo use useradd as the-M USERNAME
sudo use usermod as the -L USERNAME

The user to be added is identified by USERNAME.

It establishes a user with really no root folder and prevents them from signing in with a second operation.

To add an existing user to a group on Linux, follow the instructions:

As root, log in to your account
Use the useradd instruction to add a new user (for example, useradd roman)
If you'd like to log on as a new customer, type su plus that user's name.
Entering the word "exit" will logout you from your account.

Another way to add a user to a group under Linux would be to use the following syntax:

Alternatively, you can use the usermod command.
The name of the club should be substituted for example group in this sentence.
Example username should be replaced with the name of the user you'd like added.

The following operations are performed when a new login is added to the system.

The user's home directory (/home/username by default) is now created.
To set configuration files for the user's session, the following secret files are copied into another user's home directory.

.bash_logout

.bash_profile

.bashrc

/var/spool/mail/username includes the user's mail spool.
The new user account is arranged in groups with the same name.

Not 100% sure but I can Definitely say not b or c. So you’re narrowed down to A and D.

Here are some instructions in English. Translate each of them into the Simple Machine language.

Evgen [1.6K]

Answer:

a. LOAD register 3 with the hex value 56

2356

b. ROTATE register 5 three bits to the right.

A503

c. JUMP to the instruction at location F3 if the contents of register 7 are equal to the contents of register 0

B7F3

d. AND the contents of register A with the contents of register 5 and leave the result in register 0

80A5

Explanation:

To translate the English instructions to Machine language we have to consider Appendix C of A Simple Machine Language sheet.

a. LOAD register 3 with the hex value 56

The OP code for LOAD is:

2

Operand is:

RXY

Description is:

LOAD the register R with the bit pattern XY.

In a.

3 represents R

56 represents XY

Now following this we can join OP and Operand together to translate a.

2356

b. ROTATE register 5 three bits to the right

The OP code for ROTATE is:

A

Operand is:

R0X

Description is:

ROTATE the bit pattern in register R one bit to the right X times. Each time place the bit that started at the low-order end at the high-order end

In b.

5 represents R

three represents X

Now following this we can join OP and Operand together to translate b.

A503

c. JUMP to the instruction at location F3 if the contents of register 7 are equal to the contents of register 0.

The OP code for JUMP is:

B

Operand is:

RXY

Description is:

JUMP to the instruction located in the memory cell at address XY if the bit pattern in register R is equal to the bit pattern in register number 0.

In c.

7 represents R register

F3 represents XY

Now following this we can join OP and Operand together to translate c.

B7F3

d. AND the contents of register A with the contents of register 5 and leave the result in register 0.

The OP code for AND is:

8

Operand is:

RST

Description is:

AND the bit patterns in registers S and T and place the result in register R

In d.

A represents register S

5 represents register T

0 represents register R

Now following this we can join OP and Operand together to translate d.

How to analyze time complexity of a code?

VladimirAG [237]

Answer:

we can multiply or divide by a constant factor to get to the simplest expression. The most common metric for calculating time complexity is Big O notation. This removes all constant factors so that the running time can be estimated in relation to N as N approaches infinity.
