The 2's-complement operation on a signed number changes a positive number to a negative number and vice versa
a)False
b)True

Answers

Answer 1

False, the 2's complement operation is used to represent negative numbers in binary form, but it does not change the sign of a positive number or vice versa.

Does the 2's complement operation on a signed number change a positive number to a negative number?

The statement is false. The 2's complement operation on a signed number does not change a positive number to a negative number or vice versa. Instead, it is a method used to represent negative numbers in binary form.

In 2's complement representation, the most significant bit (MSB) is used as the sign bit. If the MSB is 0, the number is positive, and if the MSB is 1, the number is negative.

To obtain the 2's complement of a negative number, the binary representation is inverted (all bits flipped) and then 1 is added to the result.

For example, in a 4-bit system, the decimal number +3 is represented as 0011, and its 2's complement is 1101, which represents -3.

The operation does not change the sign of the number; rather, it provides a way to represent negative numbers in binary form using complementation.

Additionally, an information system or technology comprises of five (5) main components;

1. Hardware.

5. Telecommunications.

Hence, information technology or system relies on the data it receives from its environment, processes this data into formats that are usable by the end users.

What are the basic parts of sewing machine?​

Answers

Answer:

1. Spool Pin  

Thread usually comes on a spool. That is the wooden thread holder you buy in the store. The spool pin holds the spool of thread for you making it easier for you to thread your machine and keep the thread coming as you want it to. Read about the spool pin felt.

2. Bobbin Binder Spindle  

A bobbin is a little cylinder that may come with or without flanges. It holds the thread that is wound around it. The spindle is where the bobbin is placed during winding.

3. Bobbin Winder Stopper  

The bobbin is only so large. It cannot always hold the amount of thread you want to put on it. This part stops the bobbin from collecting thread when it has reached full capacity.

4. Stitch Width Dial  

On many newer sewing machines, you get a variety of stitch options to use. The purpose of this part is to control the zig-zag stitch option while you are busy concentrating on your sewing.

5. Pattern Selector Dial  

This little dial allows you to select one stitch pattern out of the many that come built into your sewing machine. You just turn the dial to get the pattern that you want on your clothes and other fabrics you want to mend or create.

6. Hand Wheel  

This is the manual needle control which raises or lowers the needle. It is usually located at the right-hand side of the machine. It shouldn’t be that hard to turn.

7. Stitch Length Dial  

More recent sewing machines may have this part attached to them. Its purpose is to control the length of your selected stitch. This helps you stay in control of your sewing duties and make sure you get what you want and need.

8. Reverse Stitch Lever  

Once you push this lever, you get to sew in the opposite direction. This function makes your sewing a little easier and faster to do because you can go forward or in reverse when you need to.

9. Power Switch  

You already know what this switch does. The key to using it is to make sure you turned your sewing machine off before you walk away. Also, it should be located at the right side of your machine.

10. Bobbin Winder Thread Guide  

When you activate this part on your sewing machine, you are guiding the thread towards the bobbin/ This makes winding your thread up a little easier and should prevent twists, tangles or caught thread.

11. Thread Tension Dial  

Tension is important when you do your sewing. Too loose can cause you problems and too much tension could snap your thread and make sewing more time consuming as you have to re-thread the machine. This little part simply controls the tension on the thread so be careful when you use it.

12. Thread Take-Up Lever  

Your top thread passes through this part as you do your sewing. The lever moves up and down with your needle so do not be alarmed that it is constantly moving.

13. Needle Clamp Screw  

Needles do not stay in place by themselves. It would be nice if they did. You need this part to hold your needle where it is supposed to be. It also makes sure your needle is secure as it moves.

14. Presser Foot  

This is the part that holds your fabric so it doe snot slip all over the place while you are working. Controlling your fabric is important while you do your sewing.

15. Bobbin Cover  

Your sewing machine parts do need some protection to keep them in top working order and to help then last you for years. This is the job of the bobbin cover. It protects the bobbin as it covers it.

16. Bobbin Cover Release Button  

Also, you need access to your bobbin when it its filled with thread or there is a problem. This release button helps you to remove the bobbin cover so you have complete access to your bobbin.

17. Feed Dog  

It is an interesting name, but it has a very straightforward function., This part feeds your fabric through the sewing machine while you are sewing. This helps you concentrate on other sewing needs as you work.

18. Needle  

Another self-explanatory label that tells you everything you need to know. The needle is an integral part of the sewing machine and without it, the other parts cannot do their job.

19. Needle Plate  

This part is located right under the needle and an under the presser foot. Its job is to help move the fabric forward as you sew. It may help help push the fabric back when you use the reverse mode on your sewing machine.
