Read -only memory(ROM)

Image
  Read-only memory  ( ROM ) is a type of  non-volatile memory  used in  computers  and other  electronic devices . Data stored in ROM cannot be electronically modified after the manufacture of the  memory device . Read-only memory is useful for storing  software  that is rarely changed during the life of the system, also known as  firmware . Software applications (like  video games ) for programmable devices can be distributed as  plug-in cartridges containing ROM .

HTML versions timeline

  HTML 3 January 14, 1997 Html 3.2 was published as a W3C Recommendation. It was the first version developed and standardized exclusively by the W3C, as the IETF had closed its HTML Working Group on September 12, 1996.  Initially code-named "Wilbur", HTML 3.2 dropped math formula entirely, reconciled overlap among various proprietary extensions, and adopted most of Netscape's visual markup tags. Netscape's bilk element and Microsoft's marquee element were omitted due to mutual agreement between the two companies. A markup for mathematical formulas similar to that in HTML was not standardized until 14 months later in MathML  

What is RAM

Image
Random-access memory  ( RAM  ) is a form of  computer memory  that can be read and changed in any order, typically used to store working  data  and  machine code . A  random-access  memory device allows  data  items to be  read  or written in almost the same amount of time irrespective of the physical location of data inside the memory. In contrast, with other direct-access data storage media such as  hard disks ,  CD-RWs ,  DVD-RWs  and the older  magnetic tapes  and  drum memory , the time required to read and write data items varies significantly depending on their physical locations on the recording medium, due to mechanical limitations such as media rotation speeds and arm movement. RAM contains  multiplexing  and  demultiplexing  circuitry, to connect the data lines to the addressed storage for reading or writing the entry. Usually more than one bit of stora...

                                                 HTML 2 November 24, 1995 HTML 2.0 was published as RFC 1866. Supplemental RFCs added capabilities: November 25, 1995: RFC 1867 (form-based file upload) May 1996: RFC 1942 (tables) August 1996: RFC 1980 (client-side image maps) January 1997: RFC 2070 (internationalization)

What is Mother Board

Image
  The  motherboard  is a printed circuit board and foundation of a computer that is the biggest board in a computer chassis. It allocates power and allows communication to and between the CPU , RAM , and all other computer hardware components.

HTML History

Image
  Development Tim Berners-Lee in April 2009 (developer of HTML5) In 1980, physicist  Tim Berners-Lee , a contractor at  CERN , proposed and prototyped  ENQUIRE , a system for CERN researchers to use and share documents. In 1989, Berners-Lee wrote a memo proposing an  Internet -based hypertext system.  Berners-Lee specified HTML and wrote the browser and server software in late 1990. That year, Berners-Lee and CERN data systems engineer  Robert Cailliau  collaborated on a joint request for funding, but the project was not formally adopted by CERN . In his personal notes from 1990 he listed "some of the many areas in which hypertext is used" and put an encyclopedia first. The first publicly available description of HTML was a document called  "HTML Tags" , first mentioned on the Internet by Tim Berners-Lee in late 1991. It describes 18 elements comprising the initial, relatively simple design of HTML . Except...

What is CPU

Image
  A central processing unit ( CPU ) is an important part of every computer. The  CPU  sends signals to control the other parts of the computer, almost like how a brain controls a body. The  CPU  is an electronic machine that works on a list of computer things to do, called instructions. It reads the list of instructions and runs ( executes ) each one in order. A list of instructions that a CPU can run is a computer program. The clock rate, or speed of a CPU's internal parts, is measured in  hertz   (Hz) . Modern processors often run so fast that gigahertz (GHz) is used instead. One GHz is 1,000,000,000 cycles per second. Most CPUs used in desktop (home) computers are microprocessors made by either Intel or Advanced Micro Devices  (usually shortened to AMD) . Some other companies that make CPUs are  ARM ,  IBM , and  AMD  under  ATI Technologies , which is the leader right ...
