The minimum voltage in RAM is 1.35V for DDR3 and 1.2V for DDR4.
DDR3 RAM has a minimum voltage of 1.35V
DDR4 RAM has a minimum voltage of 1.2V
Lower voltage RAM can help reduce power consumption and heat generation
A MAC address is a unique identifier assigned to network interfaces for communications on a network. It is 48 bits long.
MAC address stands for Media Access Control address
It is a hardware address assigned to network interfaces by the manufacturer
MAC addresses are used in Ethernet and Wi-Fi networks
They consist of six groups of two hexadecimal digits separated by colons or hyphens
Example: 00:1A:2B:3C:4D:5E
The network id for ip 192.168.0.23 is 192.168.0.0.
Identify the subnet mask for the network
Perform a bitwise AND operation between the IP address and subnet mask
The result is the network id
The subnet mask for IP 192.168.45.21 is typically 255.255.255.0.
Subnet masks determine the network and host portions of an IP address.
The default subnet mask for a Class C network is 255.255.255.0.
Subnet masks are represented in dotted decimal notation.
