    Router is a very prominent tool of the trade in setting up a workplace LAN installation, your skill level maybe just inserting the RJ45 cable far from proper true tradesman.

    Home router is all-in-one device with NAT and firewalling tackled to it.

    LAN means 'local area network', so as soon as you connect any 2 or more devices together you have created a LAN.

    A router is essential to connect between 2 different networks (e.g. your LAN and the Internet). If you were to connect your computer directly to a modem then your computer has become an integral part of the Internet and can be directly seen (and accessed) by anyone out on the Internet.

    A router provides you with several advantages:

    1. Network Address Translation (NAT) hides your computer from the Internet except to handle requests made by you.

    2. It allows more than one device to connect on your side (e.g. 2 or more computers, tablets, printers) and thus be able to talk to one another.

    3. It provides WiFi capabilities.

    4. It may contain a firewall (at least in software, but sometimes in hardware too).

    1. So you can have WiFi

    2. So you can connect multiple devices to the Internet at the same time.

    3. Router has a feature called Network Address Translation (NAT) which essentially hides your network from the Internet.

    Contrary to the other answers, routers generally don't have a firewall, it's the NAT feature which provides the security.

    There is almost no firewall from a modem. At best, you are trusting a software firewall, something that can inadvertently be turned off.

    You can't have multiple devices if the ISP only doles out one ip to you, which most currently do.

    LAN is just a connection to a internal network of devices or computers and allows for sharing of content between devices. A router is a device that translates the connection from the internal network to the external network (internet) and vice versa. It also provided protection from threats by use of a firewall which normal lan switches do not have.

    For a better firewall.
