Are you a student in this subject or simply having a go at the question?
"is it the computer requirement itself or the router?"
The reason I mention the above, isn't to sound nasty, but simply because any person with a basic understanding would know routers come under "network devices".
A computer network is a collection of interconnected devices, such as computers, printers, and servers, that communicate with each other and share resources.
Computer networks allow for efficient communication and sharing of information and resources, increased productivity, and cost savings. They also enable remote access to data and services, making it easier to work from anywhere.
To connect to a computer network, you need a network adapter, such as a network interface card (NIC) or a wireless adapter. Once you have the necessary hardware, you can connect to the network by configuring your device's network settings or by using a wireless network connection.
The most common types of computer networks include local area networks (LANs), which connect devices within a small geographic area, and wide area networks (WANs), which connect devices over a larger distance. Other types include metropolitan area networks (MANs), personal area networks (PANs), and virtual private networks (VPNs).
To ensure the security of your computer network, you should use strong passwords, keep your software and devices up to date, use firewalls and antivirus software, and regularly back up your data. It is also important to limit access to the network and regularly monitor for any suspicious activity.
