The hardware event handlers (interrupt handlers) will for instance get the number of the key you just pressed, and convert it to the corresponding character stored in a buffer so some program can retrieve it. The system calls are initiated by user-level programs, for opening files, starting o...
In computer science, a buffer is temporary storage we use when one component feeds data to the other, but their speeds aren’t the same. There can be multiple producers and consumers, but we’ll focus on the case with a single producer and only one consumer to better explain the concepts...

A buffer overflow occurs when a program or process attempts to write more data to a fixed-length block of memory, orbuffer, than the buffer is allocated to hold. Buffers contain a defined amount of data; any extra data will overwrite data values in memory addresses adjacent to the destinatio...
the main purpose of an input buffer is to decouple the input device from the processing unit of a computer system. by temporarily storing the input data in a buffer, it allows the user to input data at their own pace while the computer processes it independently. this helps to prevent ...
What is a buffer overflow? Buffer overflow refers to a common cybersecurity vulnerability that happens when a program or process writes more data into a buffer than it can handle. In other words, too much data passes into memory that doesn't have enough space. Then, the extra data ends ...
Buffer overflow is a software coding error that enables hackers to exploit vulnerabilities, steal data, and gain unauthorized access to corporate systems. Discover what is a buffer overflow attack and how Fortinet can mitigate and prevent overflow attack
This is a complete overview of open ports. Learn why open ports can be dangerous and how to detect them in this in-depth post.
RAM (Random Access Memory) is essential for a computer to store and access large amounts of data quickly. RAM works as a buffer, storing information for the time being as it is processed by the CPU. RAM is measured in bytes starting from 4 GB and up to 32 GB or more, which has ad...
● Section 2.4 PAC_INFO_BUFFER: Changed ulType value 0x00000012 PAC Requestor to PAC Requestor SID, added SID to behavior note, and added value 0x00000014 for PAC Requestor GUID. ● Section 2.15 PAC_REQUESTOR_SID: Changed name of structure from PAC_REQUESTOR to PAC_REQUESTOR_SID. ...
