Answer Details
(a) An Internet Service Provider (ISP) is a company that provides individuals and organisations with access to the Internet. [1] It connects the customer's network or device to the wider Internet infrastructure using technologies such as broadband, fibre optic or cable. [1]
(b) Two services other than Internet access:
- Email hosting: providing email accounts with a domain name, along with the infrastructure to send, receive and store emails. [1]
- Web hosting: storing a customer's website files on a server and making them available on the Internet 24/7. [1]
(c) A static IP address is permanently assigned to a device and does not change, remaining the same every time the device connects to the network. [1] A dynamic IP address is temporarily assigned to a device by a DHCP (Dynamic Host Configuration Protocol) server each time it connects, and may be different each time. [1]
(d) One advantage of a static IP address: it is essential for hosting a server or website, because other devices need to reach the server at a consistent, known address. [1] With a dynamic address, the server's IP could change, making it unreachable. [1]
