5. A pen also describes the short and usually thin piece of metal at the end of a male cable. For example, the image shows the end of a VGA connector with pins (top image) connected to the jack (bottom image) on the computer. With the introduction of Windows 8, the PIN is also extended to designate each object in a user interface (UI). For example, in Windows 8, you can also pin tiles. Windows 8 also introduced PIN sign-in, which allows users to sign in to their computer with a four-digit PIN. 2) A PIN is a personal identification number. PINs are usually assigned to bank customers for use with ATMs. They are also used, sometimes with a security token, for individual access to computer networks or other secure systems.

For NIST publications, there is usually an email in the document. (1) A pin is a serrated contact that is part of a signal interface in a computer or other communication device. The pins are part of a male plug and plug into an outlet. The number of pins on a connector is sometimes used to describe the connector (for example, «a 25-pin Type D connector»). The description of the signal associated with each pin is called pinout. A personal identification number (PIN) is a secure alphanumeric or numeric code used for authenticated access to a system. A PIN code serves as a validation tool for users of different types of networks and systems, such as: Computer networks, credit/debit cards and mobile phones. PINs are used in several industries, including banking, payment processing and communications. The PIN provides security in the event of a lost or stolen credit/debit card, as the PIN must be known before withdrawing funds.

In an Internet browser like Chrome and Firefox, a pin makes a tab in a browser tab bar smaller and permanent. Mozilla Firefox calls them application tabs. The image shows an example of a pinned tab, which is YouTube, next to a «Computer Hope» tab. If a tab is pinned, you will only see the favicon. There are many other tools to track the resource usage of programs running on the system, such as Bell Lab`s Strapon tool and Dyninst tool, etc. Bell Lab`s tool uses strap-on technology, which runs a tool to collect resources at the same time as the program, but this tool is only compatible with programs that allow other programs to run simultaneously with them. [6] In addition, the Dyninst tool uses binary rewriting of the program`s executable and implementable commands in the program to check resource usage and is very efficient. However, it is very unstable as it is a relatively new tool and crashes on large programs. [7] Finally, the Intel PIN tool uses static binary instrumentation and runs the program as part of itself while tracking all its resources. [8] This approach is more suitable for an antivirus program because it can easily run all processes on its own and stop programs if they reach a maximum limit set by the antivirus. PINs are assigned to users for secure authentication. For example, a user presents a credit/debit card for payment and enters a PIN to complete the transaction.
If the user enters an invalid PIN, the user is allowed to perform a limited number of authentication attempts. Sellers and banks may confiscate credit/debit cards if a valid PIN is not provided in a number of attempts.

The API and PIN implementation aim to make pin tools easy to write. Pin is solely responsible for ensuring that the instrumentation code of the Pin tool does not affect the state of the application. In addition, the API allows the instrumentation code to request a lot of information from the pin. For example, the instrumentation code in the Pin tool can use the Pin API to retrieve the memory address accessible by an instruction without having to examine the instruction in detail. Pin performs instrumentation by taking control of the program immediately after it is loaded into memory. Then, just-in-time (JIT) compiles small pieces of binary code with a pin just before execution. New instructions for performing an analysis are added to the newly compiled code. This new guide comes from the Pintool.
Various optimization techniques are used to achieve the lowest possible execution time and memory usage. As of June 2010, the average basic PIN surcharge is 30% (without using a pintool). [2] The location where programs or objects are pinned in Windows is sometimes referred to as pinned space. 6. The term pin describes the small metal profiles at the bottom of a processor or integrated circuit. These pins connect the processor to a socket or board. In the photo, a close-up of a processor showing how the processor pins can be bent. If the pins are bent, the processor may not work. If you`re trying to access your wireless network and don`t know a PIN, select the option to use your network key or passphrase.
1. As an abbreviation for a personal identification number, a PIN is a series of personal numbers used to prove identification. It is commonly used with ATMs, calling cards, and wireless networks. Here`s an example of how Microsoft Windows asks for a PIN when connecting to a Wi-Fi network. (3) To place an item in a Start menu, taskbar, home screen, or web page. For example, in Windows, pinning to taskbar places the app icon in the taskbar. The Mac equivalent is Keep in Dock. See Pinterest and Pinata. 4. On the Pinterest social networking platform, a PIN is a saved image or website that you have liked and that is stored in your Pinterest profile. Once pinned, others can view all your saved Pins, leave comments, or pin anything to their profile. 2.
In Microsoft Windows, pin is a term first introduced in Windows 7 that describes placing a shortcut on the taskbar or Start menu. Pinning a shortcut to the taskbar or Start gives you quick access to frequently used programs. PIN is designed for tool portability, and although JIT is compiled from an ISA to the same ISA (and does not use a single intermediate representation for all code), most of its APIs are architecture and operating system independent. It was also designed to be portable in its own right, carefully isolating platform-specific code from generic code, allowing Pin to be quickly adapted to new platforms. About half of the code is generic and the rest depends on the architecture or operating system. [3] Pin is a platform for creating analysis tools. A pin tool includes instrumentation, analysis, and reminder routines. Instrumentation routines are called when code that has not yet been recompiled needs to be executed and allow you to insert analysis routines. Analysis routines are called when the code associated with them is executed.
Callback routines are called only when certain conditions are met or when a specific event has occurred. Pin provides a rich application programming interface (API) for instrumentation at different levels of abstraction, from an instruction to an entire binary module. It also supports callbacks for many events such as library loads, system calls, signals/exceptions, and threading events. In 2020, he received the Programming Languages Software Award from ACM SIGPLAN. [1] The spindle uses many techniques to optimize instrumentation and analysis code, using techniques such as inlining, liveliness analysis, and intelligent damper dumping. If possible, Pin performs these optimizations automatically without users having to insert additional code to enable inlining. Of course, some optimizations still require user guidance, and some code structures are easier to integrate than others. Direct linking of jitted code sections, a technique called trace binding, and register link matching, which minimizes spillage and remapping of registers, are also used.
There are many pin tools that are used for different tasks. A digital secret that a cardholder remembers and uses as part of authenticating their identity.

The pin supports two instrumentation modes, called JIT mode and probe mode. JIT mode supports all of Pin`s features, while probe mode supports a limited set of features but is much faster and running the program causes almost no overhead. JIT mode uses a just-in-time compiler to recompile all program code and insert instrumentation, while probe mode uses code trampolines for instrumentation.
