(b)(i) Mention two reasons why computers are connected. (ii) Mention two reasons why computers are not connected.
(c) List four additional items needed to send an email.
(a) A home page is the main or starting page of a website that provides an overview of the website's content and navigation options. It serves as a gateway to access different sections of the website and contains links to other pages.
(b)(i) Two reasons why computers are connected include:
Communication: Computers are connected to each other to enable communication between users. With the help of the internet, users can exchange messages, share files, and collaborate on projects.
Resource sharing: Computers can be connected to share resources such as printers, scanners, and external hard drives. This enables users to access resources from other computers on the network and reduces the need for duplicate equipment.
(ii) Two reasons why computers are not connected include:
Security concerns: In some cases, computers may not be connected to prevent unauthorized access to sensitive data. This is particularly important in organizations that deal with confidential information, such as financial institutions and government agencies.
Isolation: Computers may not be connected if they are used for specialized tasks that do not require network access, such as controlling manufacturing equipment or performing scientific simulations.
(c) Four additional items needed to send an email include:
Email address of the recipient: To send an email, you need to know the email address of the person or people you want to send the email to. This is the unique identifier that tells the email system where to send the message.
Email address of the sender: You also need to provide your own email address so that the recipient can reply to your message.
Subject line: The subject line is a brief description of the email's content and helps the recipient understand what the email is about.
Message body: The message body is the main content of the email and can include text, images, and attachments. It is where you communicate your message to the recipient.
To send an email, you typically compose a new message in your email client, enter the recipient's email address, fill in the subject line and message body, and click send. The email system then routes the message to the recipient's email server, where it can be accessed using their email client.
