This is a list of file signatures, data used to identify or verify the content of a file. Such signatures are also known as magic numbers or Magic Bytes. Many file formats are not intended to be read as text. If such a file is accidentally viewed as a text file, its contents will be unintelligible.
Chinese Firewall Test - Instantly test if a URL is blocked by the Great Firewall of China in real time. Tests for both symptoms of DNS poisoning and HTTP blocking from a number of locations within mainland China. China Firewall Test - Test if any domain is DNS poisoned in China in real-time. DNS poisoning is one way in which websites can be ...
The physical hardware communications link is not defined by SCPI. While it was originally created for the IEEE-488.1 (GPIB) bus, SCPI can also be used with RS-232, RS-422, Ethernet, USB, VXIbus, HiSLIP, etc. SCPI commands are ASCII textual strings, which are sent to the instrument over the physical layer (e.g., IEEE-488.1). Commands are a ...
The file is a text file of between 68 and 128 bytes [6] that is a legitimate .com executable file (plain x86 machine code) that can be run by MS-DOS, some work-alikes, and its successors OS/2 and Windows (except for 64-bit due to 16-bit limitations). The EICAR test file will print "EICAR-STANDARD-ANTIVIRUS-TEST-FILE!" when executed and then ...
Canterbury corpus. The Canterbury corpus is a collection of files intended for use as a benchmark for testing lossless data compression algorithms. It was created in 1997 at the University of Canterbury, New Zealand and designed to replace the Calgary corpus. The files were selected based on their ability to provide representative performance ...
Each 32-bit integer from the test file provides the value for the throw of a die, by floating to [0,1), multiplying by 6 and taking 1 plus the integer part of the result. Most of the tests in DIEHARD return a p -value, which should be uniform on [0,1) if the input file contains truly independent random bits.
When categorical data has only two possibilities, it is called binary or dichotomous. [ 1 ] Assumptions, parametric and non-parametric: There are two groups of statistical tests, parametric and non-parametric. The choice between these two groups needs to be justified. Parametric tests assume that the data follow a particular distribution ...
QTI was produced by the IMS Global Learning Consortium (IMS GLC), which is an industry and academic consortium that develops specifications for interoperable learning technology. QTI was inspired by the need for interoperability in question design, and to avoid people losing or having to re-type questions when technology changes.
