Unix
Unix is one of the oldest but still most popular Operating Systems. It was invented in 1969 at AT&T Bell Labs by Ken Thompson and Dennis Ritchie. All the Contemporary operating systems of Solaris, HP-UX, Linux, AIX are variants (a form or version of something that differs in some respect from other forms of the same thing or from a standard). Unix is a family of Multi-user operating systems. How it works: A Unix system consists of several parts, or layers as I’d like to call them. To start a system, a program called the boot loader lives at the first sector of a hard disk partition. It is started by the system, and in turn it locates the Operating System kernel, and load it.
Microprocessor
In November of 1971, a company called Intel publicly introduced the worlds first single-chip Microprocessor, the Intel 4004 (U.S. Patent #3,821,715), invented by Intel engineers Federico Faggin, Ted Hoff, and Stanley Mazor. How it works: A dual-core or multi-core processor works by combining two physical cores into a central processing unit, allowing the CPU to handle multiple threads of data at once. The core of a CPU is the part that does all of the actual work.
Video Game Console
The first generation of videos game consoles began in 1972 with the Magnavox (Latin for “great voice”. Magnavox is an American electronic company founded in the Untied States.Today it is a subsidiary of electronic corporation Philips.) Odyssey (which began development in 1968 by Ralph Baer under the code name “The Brown Box”), until 1977, when “pong-style console manufactures left the market en masse due to the video game crash of 1977 and when microprosser-based consoles were introduced. How it works: A video game is a system of complex codes that are put into the game by a programmer and then interpreted and displayed by a personal computer or video game system. Video game systems, often called consoles, all have different hardware and require different codes to work.
VHS and VCR
The first VCR to use VHS standard was the Victor HR-3300, and was introduced by the president of JVC on September 9, 1976. The United States did not receive its first VHS-based VCR, the RCA VBT200, until August 23, 1977. Despite VHS and Betamax being the major companies in the VCR market, other competitors still existed. I would tell you how they work, but its a video and I don’t know how to put links on here.
