  • 09:3509:35, 1 October 2024 diff hist +482 N Glossary:Buffer overflow vulnerabilityCreated page with "A buffer overflow happens when a program is given more data (whether direct user input or from a network source) than will fit in the memory space that has been allocated for it. The extra may then overwrite nearby data causing unexpected behaviour, which may include an attacker being able to take over control of the program. Buffer overflows can be avoided by strict adherence to a cardinal rule of secure coding: thoroughly validate all input from potentially untrusted s..." current

Sometimes, due to a bug, it may fail to return it to the pool when it's finished with it. This is known as a memory leak, and can result in the memory pool becoming depleted to the extent that the software can no longer operate. The only solution is to close and relaunch it." current

This is subtly different from the description of the page's purpose, given above. Retaining the basic structure, replace all the text of this page with your own content...."

  • 10:2110:21, 28 August 2024 diff hist +515 N Glossary:Floating PointCreated page with "Many of the numbers a computer deals with are whole numbers (integers) which can be easiy represented in binary, but real world numbers can span a huge range of sizes. Floating point is a method of representing such numbers in two parts: a mantissa represents the significant digits and an exponent tells you where the decimal point comes (or the binary point for binary numbers). This is similar to the scientific notation in which one and a half million..." current
  • 10:0610:06, 28 August 2024 diff hist +386 N Glossary:RISC-VCreated page with "RISC-V (pronounced Risk Five) is a RISC computer architecture with its roots in an academic design at Berkley. There are 32 and 64 bit variants of the basic design and numerous optional extensions giving additional instructions for different data types and types of operation. Unlike ARM, the design is completely open source." current
  • 09:4109:41, 28 August 2024 diff hist +522 N Glossary:ARMCreated page with "ARM, or Advanced RISC Machines is a computer architeture designed for low cost and low power consumption. It is used in huge numbers of smartphones but equally, supercomputers have been built using large swarms of them. It was first introduced in 1985 by Acorn Computers (also known for their BBC Micro) but it has since gone through several generations. The design is owned by Arm Ltd who licence it to..." current

  • 09:0109:01, 28 August 2024 diff hist +493 N Glossary:RISCCreated page with "RISC or Reduced Instruction Set Computer is a computer architecture in which the basic machine instructions are very simple and so can be implemented cheaply. Although more instructions may be needed for a given task, they can be made to run very fast and the silicon saved can be used for other optimisations such as large cache memories to speed up execution. The result can be a significant net gain in performance. ARM is the most widely used example of..." current
  • 08:4308:43, 28 August 2024 diff hist +370 N Glossary:CISCCreated page with "CISC or Complex Instruction Set Computer is a computer architecture in which the basic machine instructions are generally fairly complex and highly functional, however, this means that they are relatively expensive to implement. By comtrast, the RISC or Reduced Instruction Set Computer architecture was developed to optimise performance in other ways."
