Negative numbers are encoded using the two’s complement technique. Two's complement is used to encode negative numbers.
Option A is correct .
<h3>What method does the in data type use to store negative numbers?</h3>
Most implementations you're likely to encounter store negative signed integers in a form known as two's complement. Another important way of storing negative signed numbers is called one's complement. The one's complement of an N-bit number x is basically defined as x with all bits inverted.
<h3>What is encoding method?</h3>
An encoding technique is the application of established industry conventions to a coded character set to create a coded character scheme. Such rules determine the number of bits required to store the numeric representation of a given character and its code position in the encoding.

Answer:
David can apply filter to the data in order to show only records that meet the criteria.
Explanation:
- Filter is a very helpful option that displays the records that you want to view, hiding rest of the unwanted records.
- Sometimes you want to extract and view only the records that match a specific criteria instead of viewing all the records.
- For example in the CUSTOMERS table which contains names, addresses, countries of customers. There are several customers from different countries but you only want to view the customers from Spain. So you can use filter feature to view all the customers from country Spain.
- In MS Access you can apply filters using Sort & Filter group in the Home tab by selecting the desired column. In SQL, WHERE clause can be used along with SELECT to for filtering and extracting certain records. SELECT will select the records from the table and WHERE clause will specify the criteria to select the certain records.
Computer networks allow an unlimited amount of computers to communicate with each other. This is especially useful in enterprise environments, as technicians have to deal with hundreds of computers at a time. Computer networks make it easier to share files, increase storage capacity, better communication, easier to to control computers remotely, easier to share resources, ability to share a single internet connection on multiple devices. Computer networks also have a lot of cost benifits too, as network administration is centralised, meaning that less IT support is required, and you can cut costs on sharing peripherals and internet access.
Hopefully this helps you out!
