Membrane attack complex (Terminal complement complex C5b-9) A membrane attack complex attached to a pathogenic cell The membrane attack complex (MAC) or terminal complement complex (TCC) is a complex of proteins typically formed on the surface of pathogen cell membranes as a result of the activation of the host's complement system, and as such is an effector of the immune system.
However, this problem can be solved using MAC spoofing. The user has to spoof the new MAC address so that it appears to be the address that was in use when the software was registered. [citation needed] Legal issues might arise if the software is run on multiple devices at once by using MAC spoofing. At the same time, the user can access ...
Macrophage-1 antigen (or integrin α M β 2 or macrophage integrin or Mac-1) is a complement receptor ("CR3") consisting of CD11b (integrin α M) and CD18 (integrin β 2). [1] The integrin α chain is noncovalently bound to the integrin β chain. It binds to iC3b and can be involved in cellular adhesion, binding to the intercellular adhesion ...
Complement-dependent cytotoxicity (CDC) is an effector function of IgG and IgM antibodies.When they are bound to surface antigen on target cell (e.g. bacterial or viral infected cell), the classical complement pathway is triggered by bonding protein C1q to these antibodies, resulting in formation of a membrane attack complex (MAC) and target cell lysis.
In computer networking, a media access control attack or MAC flooding is a technique employed to compromise the security of network switches.The attack works by forcing legitimate MAC table contents out of the switch and forcing a unicast flooding behavior potentially sending sensitive information to portions of the network where it is not normally intended to go.

Spoofing happens when someone sends emails making it look like it they were sent from your account. In reality, the emails are sent through a spoofer's non-AOL server. They show your address in the "From" field to trick people into opening them and potentially infecting their accounts and computers. Differences between hacked and spoofed
20] In this example, the sender of a message runs it through a MAC algorithm to produce a MAC data tag. The message and the MAC tag are then sent to the receiver. The receiver in turn runs the message portion of the transmission through the same MAC algorithm using the same key, producing a second MAC data tag.
