The  Unix  operating system was conceived and implemented in 1969, at  AT&T 's  Bell Labs , in the United States by  Ken Thompson ,   Dennis Ritchie ,   Douglas McIlroy , and  Joe Ossanna . [41]  First released in 1971, Unix was written entirely in  assembly language , as was common practice at the time. In 1973, in a key pioneering approach, it was rewritten in the  C  programming language by Dennis Ritchie (with the exception of some hardware and I/O routines). The availability of a  high-level language  implementation of Unix made its  porting  to different computer platforms easier. [42

An  embedded system  is a  computer system —a combination of a  computer processor ,   computer memory , and  input/output  peripheral devices—that has a dedicated function within a larger mechanical or  electronic  system. [1] [2]  It is embedded as part of a complete device often including electrical or electronic hardware and mechanical parts. Because an embedded system typically controls physical operations of the machine that it is embedded within, it often has  real-time computing  constraints. Embedded systems control many devices in common use today. [3]  In 2009 , it was estimated that ninety-eight percent of all microprocessors manufactured were used in embedded systems.

Very large-scale integration  ( VLSI ) is the process of creating an integrated circuit (IC) by combining millions or  billions  of  MOS transistors  onto a single chip. VLSI began in the 1970s when  MOS integrated circuit  (Metal Oxide Semiconductor) chips were developed and then widely adopted, enabling complex  semiconductor  and  telecommunication  technologies. The  microprocessor  and  memory chips  are VLSI devices.

CCNA  ( Cisco Certified Network Associate ) is an  information technology  (IT) certification from  Cisco Systems . CCNA certification is an associate-level Cisco Career certification. [1]

Linux  ( / ˈ l ɪ n ʊ k s /   LIN -uuks ) [11]  is a family of  open-source   Unix-like   operating systems  based on the  Linux kernel , [12]  an  operating system kernel  first released on September 17, 1991, by  Linus Torvalds

WordPress  (also known as  WP  or  WordPress.org ) is a  web content management system . It was originally created as a tool to publish  blogs  but has evolved to support publishing other web content, including more traditional websites,   mailing lists  and  Internet forum , media galleries, membership sites,   learning management systems  and  online stores .
