In computer security, a drive-by download is the unintended download of software, typically malicious software. The term "drive-by download" usually refers to a download which was authorized by a user without understanding what is being downloaded, such as in the case of a Trojan horse. In other cases, the term may simply refer to a download ...
For example, for a 64-bit bus partitioned into eight 8-bit subbuses the average number of transitions per time-slot will be 26.16 (8 times 3.27, the average for one 8-bit subbus) and the average number of transitions per bus-line per time-slot will be 0.41 (as for an 8-bit bus with one invert line).
Lighting and reflection calculations, as in the video game OpenArena, use the fast inverse square root code to compute angles of incidence and reflection.. Fast inverse square root, sometimes referred to as Fast InvSqrt() or by the hexadecimal constant 0x5F3759DF, is an algorithm that estimates , the reciprocal (or multiplicative inverse) of the square root of a 32-bit floating-point number in ...
Some emails contain malicious content or attachments, and email tracking is used to detect how fast these viruses or malicious programs can spread. [13] At the same time, generally, the deliverability of tracked emails is reduced up to 85%, as the firewalls of company servers embed algorithms to filter out emails with suspicious contents.
It employs two comparators to detect over-voltage or under-voltage. [2] Each single comparator detects the common input voltage against one of two reference voltages, normally upper and lower limits. [3] Outputs behind a logic gate like AND detect the input as in range of the so-called "window" between upper and lower reference.
Microsoft originally used PhotoDNA on its own services including Bing and OneDrive. [31] As of 2022, PhotoDNA was widely used by online service providers for their content moderation efforts [10] [32] [33] including Google's Gmail, Twitter, [34] Facebook, [35] Adobe Systems, [36] Reddit, [37] and Discord.
The translated code gets stored in spare memory, typically at the end of the address space, which segmentation mechanisms can protect and make invisible. For these reasons, VMware operates dramatically faster than emulators, running at more than 80% of the speed that the virtual guest operating system would run directly on the same hardware.
The open collector transistor can be rated to withstand a higher voltage than the chip supply voltage. This technique is commonly used by logic circuits operating at 5 V or lower to drive higher voltage devices such as electric motors, LEDs in series, [8] 12 V relays, 50 V vacuum fluorescent displays, or Nixie tubes requiring more than 100 V.
