TCP/IP
TCP/IP stands for Transmission Control Protocol/Internet Protocol, which is a suite of communication protocols used to interconnect network devices on the internet.
IPv4 vs IPv6
IPv4 uses 32-bit addresses resulting in 4.3 billion possible addresses, while IPv6 uses 128-bit addresses resulting in a significantly larger number of possible addresses. IPv6 also includes improvements such as simplified headers for routing efficiency.
Subnetting
Subnetting is the practice of dividing a network into two or more smaller networks. It’s used to improve network performance and security.
HTTP and HTTPS
HTTP stands for Hypertext Transfer Protocol and uses port 80. HTTPS stands for HTTP Secure and uses port 443. HTTPS is the secure version of HTTP, encrypting the data for secure transmission.
FTP
FTP stands for File Transfer Protocol and uses ports 20 and 21. It is used to transfer files between a client and a server on a network.
DNS
DNS stands for Domain Name System and uses port 53. It translates domain names to IP addresses so browsers can load Internet resources.
LAN
LAN stands for Local Area Network. It refers to a network or a portion of a network that is not publicly accessible to the greater internet. A LAN is typically owned, controlled, and managed by a single person or organization.
WAN
WAN stands for Wide Area Network. It’s a network that extends over a large geographical area for the purpose of transmitting data between different LANs.
PAN
PAN stands for Personal Area Network. It’s a network for interconnecting devices centered around an individual person’s workspace.
MAN
MAN stands for Metropolitan Area Network. It’s a network that interconnects users with computer resources in a geographic area or region larger than that covered by a LAN but smaller than the region covered by a WAN.
