Drum Memory
Drum memory was a magnetic data storage device invented by Gustav Tauschek in 1932 in Austria. Drums were widely used in the 1950s and into the 1960s as computer memory. Many early computers, called drum computers or drum machines, used drum memory as the main working memory of the computer. Some drums were also used as Auxiliary memory, secondary storage as for example various IBM_drum_storage, IBM drum storage drives and the UNIVAC FASTRAND series of drums. Drums were displaced as primary computer memory by magnetic core memory, which offered a better balance of size, speed, cost, reliability and potential for further improvements. Drums were then replaced by hard disk drives for secondary storage, which were both less expensive and offered denser storage. The manufacturing of drums ceased in the 1970s. Technical design A drum memory or drum storage unit contained a large metal cylinder, coated on the outside surface with a ferromagnetic recording material. It could be ...

Transistor
A transistor is a semiconductor device used to Electronic amplifier, amplify or electronic switch, switch electrical signals and electric power, power. It is one of the basic building blocks of modern electronics. It is composed of semiconductor material, usually with at least three terminal (electronics), terminals for connection to an electronic circuit. A voltage or Electric current, current applied to one pair of the transistor's terminals controls the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Some transistors are packaged individually, but many more in miniature form are found embedded in integrated circuits. Because transistors are the key active components in practically all modern electronics, many people consider them one of the 20th century's greatest inventions. Physicist Julius Edgar Lilienfeld proposed the concept of a field-effect transisto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Processing Unit
A central processing unit (CPU), also called a central processor, main processor, or just processor, is the primary Processor (computing), processor in a given computer. Its electronic circuitry executes Instruction (computing), instructions of a computer program, such as arithmetic, logic, controlling, and input/output (I/O) operations. This role contrasts with that of external components, such as main memory and I/O circuitry, and specialized coprocessors such as graphics processing units (GPUs). The form, CPU design, design, and implementation of CPUs have changed over time, but their fundamental operation remains almost unchanged. Principal components of a CPU include the arithmetic–logic unit (ALU) that performs arithmetic operation, arithmetic and Bitwise operation, logic operations, processor registers that supply operands to the ALU and store the results of ALU operations, and a control unit that orchestrates the #Fetch, fetching (from memory), #Decode, decoding and ...

Transistor Computer
A transistor computer, now often called a second-generation computer, is a computer which uses discrete transistors instead of vacuum tubes. The first generation of electronic computers used vacuum tubes, which generated large amounts of heat, were bulky and unreliable. A second-generation computer, through the late 1950s and 1960s featured circuit boards filled with individual transistors and magnetic-core memory. These machines remained the mainstream design into the late 1960s, when integrated circuits started appearing and led to the third-generation computer. History The University of Manchester's experimental Transistor Computer was first operational in November 1953 and it is widely believed to be the first transistor computer to come into operation anywhere in the world. There were two versions of the Transistor Computer, the prototype, operational in 1953, and the full-size version, commissioned in April 1955. The 1953 machine had 92 point-contact transistors and 5 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mainframe Computer
A mainframe computer, informally called a mainframe or big iron, is a computer used primarily by large organizations for critical applications like bulk data processing for tasks such as censuses, industry and consumer statistics, enterprise resource planning, and large-scale transaction processing. A mainframe computer is large but not as large as a supercomputer and has more processing power than some other classes of computers, such as minicomputers, server (computing), servers, workstations, and personal computers. Most large-scale computer-system architectures were established in the 1960s, but they continue to evolve. Mainframe computers are often used as servers. The term ''mainframe'' was derived from the large cabinet, called a ''main frame'', that housed the central processing unit and main computer memory, memory of early computers. Later, the term ''mainframe'' was used to distinguish high-end commercial computers from less powerful machines. Design Modern mainfr ...

Tsubame (train)
The is a train service operated by Kyushu Railway Company (JR Kyushu) on the Kyushu Shinkansen in Japan since 2004. The word in Japanese means "swallow", and has been used on a succession of limited express trains on the Tokaido and Sanyo Main Line in Japan since 1930. History Pre-war The ''Tsubame'' name (originally written as "燕") was first used from 1 October 1930 for limited express services operating between and , hauled by JNR Class C51 and JNR Class C53 steam locomotives. These services operated until 30 September 1943. Post-war The name was revived (this time written as "つばめ") from 1 January 1950 for limited express services operating between Tokyo and , hauled by JNR Class C62 steam and JNR Class EF58 electric locomotives, and later by 151 series electric multiple unit (EMU) trains. From 1 October 1964, following the opening of the Tōkaidō Shinkansen, the name was reassigned to limited express trains operating between and . From 1 October 1965 ...

Kodama (train)
is one of the three train services running on the Tōkaidō and San'yō Shinkansen lines. Stopping at every station, the ''Kodama'' is the slowest Shinkansen service for trips between major cities such as Tokyo and Osaka. The Kodama trains are used primarily for travel to and from smaller cities such as Atami. Travelers between major cities generally take the '' Nozomi'' or '' Hikari'' services, which make fewer stops, although the ''Nozomi'' requires paying a supplement under the Japan Rail Pass while the ''Kodama'' does not, making these services an affordable alternative. Services ''Kodama'' trains generally run over shorter distances than ''Nozomi'' and ''Hikari'' trains. Typical ''Kodama'' runs include Tokyo - Nagoya / Shin-Osaka, Tokyo - Mishima / Shizuoka / Hamamatsu, Mishima / Shizuoka / Nagoya - Shin-Osaka, and Shin-Osaka / Okayama / Hiroshima - Hakata as well as some shorter late-night runs. The trainsets used for ''Kodama'' service are the same 700 series, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
