1. WHAT IS NETWORK?
- A network consists of two or more computers that are linked in
order to share resources, exchange files, or allow electronic
communications.
- The computers on a network may be linked through cables.
2. WHAT IS ROUTER?
- A router is a device that connects two or more packet-switched
networks or subnetworks.
- It serves two primary functions: managing traffic between these
networks by forwarding data packets to their intended IP addresses, and
allowing multiple devices to use the same Internet connection.
3. WHAT IS PING COMMAND?
- Ping is a command-line utility, available on virtually any operating
system with network connectivity that acts as a test to see if a networked
device is reachable.
- The ping command sends a request over the network to a specific
device.
- A successful ping results in a response from the computer that was
pinged back to the originating computer.
4. WHICH KIND OF CABLES ARE USE FOR INTERNET?
- ETHERNET CABLES ARE USED FOR INTERNET.
- CAT5E AND CAT6, WHICH ARE CONNECTED TO RJ45.
5. WHAT IS FIREWALL?
- A Firewall is a network security device that monitors and filters
incoming and outgoing network traffic based on an organization’s
previously established security policies.
- At its most basic, a firewall is essentially the barrier that sits
between a private internal network and the public Internet.
- A firewall’s main purpose is to allow non-threatening traffic in and
to keep dangerous traffic out.
