5) in the late 1900s go to An Wang (王安), Way-Dong Woo (Harvard University), and Jay Forrester (MIT). Today, computer RAMs are semiconductor memory made of transistors in integrated circuits on chips. Working for Texas Instruments, Jack Kilby demonstrated the first working sample integrated circuit on September 12, 1958. Kilby won the 2000 Nobel Prize in Physics for his contribution to the invention of the integrated circuit. Integrated circuits are fabricated onto silicon wafers using a photographic printing process.

2). 2, we count starting from zero. 2 Bit, Byte, and Word In a computer, the Central Processing Unit (CPU) is where logic computation on data takes place. The CPU loads data from memory in order to process them, then stores the results back to memory. A word is normally the smallest integral data entity a CPU is designed to manipulate. The size of the word, measured in bits, is determined by the size of CPU registers. A CPU register is able to load from and store to cache/RAM (Random Access Memory) all its bits as a unit at once.

1). As an example, here is the author’s Chinese name with Unicode in hex. U+738B 王 U+58eb 士 U+5f18 弘 Among different Unicode encoding formats, UTF-8 is the most widely used. The Demo: UnicodeLookup tool at the CT website shows the UNICODE of any character you input. UTF-8 UTF-8 is a particularly efficient and widely used encoding format for Unicode. UTF-8 encodes each Unicode code point using 1 to 4 octets (an octet is 8 bits or a byte in the Unicode standard). Earlier positions in the Unicode character set, which are used more often, require fewer bytes.
