WiFi Direct is a technology that enables two compatible devices to establish a direct Wi-Fi connection without the need for a wireless access point. This is useful for sharing files, streaming media, and other activities. On a PC, WiFi Direct can be used to connect to compatible devices, such as printers, speakers, and other PCs.

Half duplex is a communication system in which two parties can communicate with each other, but not simultaneously. The parties take turns transmitting and receiving signals. Full duplex is a communication system in which two parties can communicate with each other simultaneously. Both parties can transmit and receive signals at the same time.

To convert from binary to decimal, you need to use the following formula:

Decimal = (sum of (2^n)*b(n))

where:

• n is the power of two
• b(n) is the binary digit at the nth position, starting from the right

For example, the binary number 10010101 would convert to decimal:

Decimal = (2^7)*1 + (2^6)*0 + (2^5)*0 + (2^4)*1 + (2^3)*0 + (2^2)*1 + (2^1)*0 + (2^0)*1
Decimal = 128 + 0 + 0 + 16 + 0 + 4 + 0 + 1
Decimal = 149

Security architecture is a framework of policies and procedures that govern the security of an organization’s information systems, networks, and data.
