Answer:

An OS software that acts as an interface between the computer components of the hardware and the user. At least one operating system must be available to each computer system to run other programs. Applications such as browsers, the MS Office, notepad games need a certain environment in which to execute their tasks.

Explanation:

Batch Operating System:-

Each user prepares his/her job on an offline device such as a punch card in this type of operating system and sends it to the computer operator.

Multi-Tasking:-

Timesharing allows people located on a different terminal(shell) to simultaneously operate a single computer system. The time of the processor (CPU) shared between several users is called time-sharing.

Real-time OS:-

An interval of time for processing and reacting to inputs in real-time is very small. For example, Real-time OS is an example of military software systems, spatial software systems.

Network Operating System:-

The operating network system is running on a server. It offers the ability to manage data, users, groups, security, apps, and other networking features.

Ivan

Answer:

enables you to make changes to one part of an image without accidentally changing other parts

Explanation:

Computer aided designs incorporate the use of multiple layers in drawings. The first layer is known as the layer 0, while the present layer the designer is working on is known as the current layer. The advantage of the incorporation of layers in designs include the following

1. It helps objects to be altered, grouped, hidden and moved as the designer wishes.

2. Layers can be grouped and worked on separated and common properties like color and line weight assigned to them.

3. Layers can be manipulated as the user wishes. They can be locked, frozen, turned off, etc.  Locking prevents accidental changes being made on objects.
