In cryptanalysis and computer security, password cracking is the process of guessing passwords [1] protecting a computer system. A common approach (brute-force attack) is to repeatedly try guesses for the password and to check them against an available cryptographic hash of the password. [2] Another type of approach is password spraying, which ...
Password strength is specified by the amount of information entropy, which is measured in shannon (Sh) and is a concept from information theory. It can be regarded as the minimum number of bits necessary to hold the information in a password of a given type.
BitLocker is a logical volume encryption system. (A volume spans part of a hard disk drive, the whole drive or more than one drive.) When enabled, TPM and BitLocker can ensure the integrity of the trusted boot path (e.g. BIOS and boot sector), in order to prevent most offline physical attacks and boot sector malware.
AOL Basic Mail gives you access to your email even if your computer isn't running at the highest capacity. While all AOL products do work best with the latest version of a browser, basic mail may still work in outdated browsers.
A 64-bit word can be expressed as a sequence of 16 hexadecimal digits. In computer architecture, 64-bit integers, memory addresses, or other data units [a] are those that are 64 bits wide. Also, 64-bit central processing units (CPU) and arithmetic logic units (ALU) are those that are based on processor registers, address buses, or data buses of ...
All 32-bit editions of Windows 10, including Home and Pro, support up to 4 GB. [286] 64-bit editions of Windows 10 Education and Pro support up to 2 TB, 64-bit editions of Windows 10 Pro for Workstations and Enterprise support up to 6 TB, while the 64-bit edition of Windows 10 Home is limited to 128 GB.

User space and kernel space. A modern computer operating system usually uses virtual memory to provide separate address spaces or separate regions of a single address space, called user space and kernel space. [1][a] Primarily, this separation serves to provide memory protection and hardware protection from malicious or errant software behaviour.
