3. The five common features that you need to be aware of before you start using your email are:
1. Inbox: The inbox is the main folder where all the incoming messages are stored. It is important to regularly check your inbox for new emails.
2. Compose: The "Compose" function allows you to create and send new emails. You can type in the recipient's email address, subject, and the body of the message in this function.
3. Send/Receive: This feature enables you to send and receive emails. When you click on the "Send/Receive" button, your email client will connect to the email server and check for new emails. It also sends any emails from your outbox that are waiting to be sent.
4. Attachments: With this feature, you can attach files such as documents, images, or videos to your emails. Most email clients have an "Attach" button that lets you browse and select the file you want to attach.
5. Trash/Deleted Items: The "Trash" or "Deleted Items" folder is where all the deleted emails are stored temporarily before they are permanently deleted. It is advisable to regularly empty your trash folder to free up storage space.
4. Functions of an operating system:
1. Process management: The operating system manages various processes running on a computer. It allocates resources such as CPU time, memory, and input/output devices to different processes, ensuring efficient multitasking.
2. Memory management: This function involves managing the computer's physical and virtual memory. The operating system assigns and deallocates memory to different processes, optimizing memory usage and preventing memory conflicts.
3. File system management: The operating system provides a file system that organizes and stores files on storage devices such as hard drives or solid-state drives. It allows users to create, access, modify, and delete files and directories.
4. Device management: The operating system controls and coordinates the usage of different hardware devices attached to the computer, such as printers, scanners, and network adapters. It provides device drivers that allow the operating system to communicate with these devices.
5. User interface: The operating system provides a user interface (UI) through which users interact with the computer. This can be a command-line interface (CLI) or a graphical user interface (GUI), enabling users to execute commands, run applications, and manage files easily.
