The 10 important network concepts
-What is the IP Address?
(Internet Protocol) IP address is a unique numerical address that assigned to each device on a network to identify and locate it on the internet.
-What is the difference between IPv4 and IPv6?
The main difference between IPv4 and IPv6 is the address size of IP addresses. The IPv4 is a 32-bit address, whereas IPv6 is a 128-bit hexadecimal address it provides a large address space to supply IP addressing and additional security.
-What is a Subnet Mask?
Subnet mask is used to divide the IP network into subnetworks by specifying which portion of the address is the network and which portion is the host.
-What is the MAC Address?
MAC address is a Media Access Control address, which identifies different devices in the same local network.
-What is the Router?
Router is a network device that forwards data packets between different computer networks and allowing multiple devices to use the same Internet connection.
-What is OSI Model?
The OSI model is a conceptual framework, the communications between a computing system are split into seven different abstraction layers from physical layer to application layer.
-What is a Firewall?
A firewall is a network security device that monitors filters incoming and outgoing network traffic based on predefined security rules set by an organization.
-What is DNS, and why is used?
DNS (Domain Name System), translates human readable domain names into IP addresses, allowing users to access websites by name rather than IP address.
-What is a DHCP Server?
A DHCP server uses the Dynamic Host Configuration Protocol to automatically assign IP addresses and configuration information to devices on the network.
-What is the meaning of (NAT)?
Network Address Translation (NAT) is a service that enables private IP networks to use the internet and cloud. NAT translates private IP addresses in an internal network to a public IP address before packets are sent to an external network.
