Toshiba T3100
The Toshiba T3100 is a discontinued portable PC manufactured by Toshiba released in 1986. It features a hard drive, 8 MHz Intel 80286 CPU and a black & orange 9.5" gas-plasma display with a resolution of 640 × 400 pixels. The portable has a special high-resolution 640 × 400 display mode which is similar to and partially compatible with the Olivetti/AT&T 6300 graphics. The base model has 640 KB memory. There is a single proprietary expansion slot for 1200 bit/s modem, expansion chassis for 5x 8-bit ISA cards, Ethernet NIC, 2400 bit/s modem, and a 2 MB memory card (thus 2.6 MB in max total). T3100e model has 1 MB of memory, which can be upgraded to 5 MB. Toshiba T3100 is not a true portable, because it needs an external power source in all except the last version. Five versions exist: *The T3100/20 is essentially the same as the base T3100 but with a larger hard drive (20 MB instead of 10 MB). *The T3100e has a 12 MHz 80286 CPU (switchable to 6 ...

Toshiba
is a Japanese multinational electronics company headquartered in Minato, Tokyo. Its diversified products and services include power, industrial and social infrastructure systems, elevators and escalators, electronic components, semiconductors, hard disk drives, printers, batteries, lighting, as well as IT solutions such as quantum cryptography. It was formerly also one of the biggest manufacturers of personal computers, consumer electronics, home appliances, and medical equipment. The Toshiba name is derived from its former name, Tokyo Shibaura Denki K.K. which in turn was a 1939 merger between Shibaura Seisaku-sho (founded in 1875) and Tokyo Denki (founded in 1890). The company name was officially changed to Toshiba Corporation in 1978. A technology company with a long history and sprawling businesses, Toshiba is a household name in Japan and has long been viewed as a symbol of the country's technological prowess post-World War II. As a semiconductor company and the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Network Interface Controller
A network interface controller (NIC, also known as a network interface card, network adapter, LAN adapter and physical network interface) is a computer hardware component that connects a computer to a computer network. Early network interface controllers were commonly implemented on expansion cards that plugged into a computer bus. The low cost and ubiquity of the Ethernet standard means that most newer computers have a network interface built into the motherboard, or is contained into a USB-connected dongle, although network cards remain available. Modern network interface controllers offer advanced features such as interrupt and Direct memory access, DMA interfaces to the host processors, support for multiple receive and transmit queues, partitioning into multiple logical interfaces, and on-controller network traffic processing such as the TCP offload engine. Purpose The network controller implements the electronic circuitry required to communicate using a specific physica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM PC Compatibles
An IBM PC compatible is any personal computer that is hardware- and software-compatible with the IBM Personal Computer (IBM PC) and its subsequent models. Like the original IBM PC, an IBM PC–compatible computer uses an x86-based central processing unit, sourced either from Intel or a second source like AMD, Cyrix or other vendors such as Texas Instruments, Fujitsu, OKI, Mitsubishi or NEC and is capable of using interchangeable commodity hardware such as expansion cards. Initially such computers were referred to as PC clones, IBM clones or IBM PC clones, but the term "IBM PC compatible" is now a historical description only, as the vast majority of microcomputers produced since the 1990s are IBM compatible. IBM itself no longer sells personal computers, having sold its division to Lenovo in 2005. "Wintel" is a similar description that is more commonly used for modern computers. The designation "PC", as used in much of personal computer history, has not meant "personal c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toshiba T1000
The Toshiba T1000 is a discontinued laptop manufactured by the Toshiba, Toshiba Corporation in 1987. It has a similar specification to the IBM PC Convertible, with a 4.77 MHz 80C88 processor, 512 KB of RAM, and a monochrome Color Graphics Adapter, CGA-compatible Liquid crystal display, LCD. Unlike the Convertible, it includes a standard serial port and parallel port, connectors for an external monitor, and a real-time clock. Unusually for an IBM compatible PC, the T1000 contains a 256 KB ROM with a copy of MS-DOS 2.11. This acts as a small, read-only hard drive. Alternative operating systems can still be loaded from the floppy drive, or (if present) the RAM disk. Along with the Toshiba T1200, T1200 and earlier Toshiba T1100, T1100, the Toshiba T1000 was one of the early computers to feature a "laptop" form factor and battery-powered operation.

BYTE
The byte is a unit of digital information that most commonly consists of eight bits. Historically, the byte was the number of bits used to encode a single character of text in a computer and for this reason it is the smallest addressable unit of memory in many computer architectures. To disambiguate arbitrarily sized bytes from the common 8-bit definition, network protocol documents such as the Internet Protocol () refer to an 8-bit byte as an octet. Those bits in an octet are usually counted with numbering from 0 to 7 or 7 to 0 depending on the bit endianness. The size of the byte has historically been hardware-dependent and no definitive standards existed that mandated the size. Sizes from 1 to 48 bits have been used. The six-bit character code was an often-used implementation in early encoding systems, and computers using six-bit and nine-bit bytes were common in the 1960s. These systems often had memory words of 12, 18, 24, 30, 36, 48, or 60 bits, corresponding t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
I386SX
The Intel 386, originally released as the 80386 and later renamed i386, is the third-generation x86 architecture microprocessor from Intel. It was the first 32-bit processor in the line, making it a significant evolution in the x86 architecture. Pre-production samples of the 386 were released to select developers in 1985, while mass production commenced in 1986. The 386 was the central processing unit (CPU) of many workstations and high-end personal computers of the time. The 386 began to fall out of public use starting with the release of the i486 processor in 1989, while in embedded systems the 386 remained in widespread use until Intel finally discontinued it in 2007. Compared to its predecessor the Intel 80286 ("286"), the 80386 added a three-stage instruction pipeline which it brings up to total of 6-stage instruction pipeline, extended the architecture from 16-bits to 32-bits, and added an on-chip memory management unit. This paging translation unit made it muc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethernet
Ethernet ( ) is a family of wired computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN). It was commercially introduced in 1980 and first standardized in 1983 as IEEE 802.3. Ethernet has since been refined to support higher bit rates, a greater number of nodes, and longer link distances, but retains much backward compatibility. Over time, Ethernet has largely replaced competing wired LAN technologies such as Token Ring, FDDI and ARCNET. The original 10BASE5 Ethernet uses a thick coaxial cable as a shared medium. This was largely superseded by 10BASE2, which used a thinner and more flexible cable that was both less expensive and easier to use. More modern Ethernet variants use Ethernet over twisted pair, twisted pair and fiber optic links in conjunction with Network switch, switches. Over the course of its history, Ethernet data transfer rates have been increased from the original to the lates ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toshiba T Series
The Toshiba T series comprises personal computers sold internationally by the Japanese electronics conglomerate Toshiba, under their Information Systems subsidiary (now known as Dynabook Inc.), from 1981 to 1995. The T series began with desktop computers such as the T100 and T300, both of which were rebranded Pasopia models from Japan for United States markets. Starting with the fast-selling Toshiba T1100 laptop, the vast majority of succeeding entries in the T series comprised portable computers, including laptops, luggables, and notebooks, as Toshiba had largely abandoned the international desktop market, where they had failed to gain much uptake. The ''T'' prefix denotes models sold exclusively outside of Japan; within Japan, Toshiba sold these computers with the ''J'' prefix instead. Beginning with Toshiba's T1800 laptop in 1992, Toshiba began introducing brand names to go alongside certain T-series models (in the T1800's case, Satellite). This practice continued until Jun ...

Olivetti M24
The Olivetti M24 is a computer that was sold by Olivetti in 1983 using the Intel 8086 CPU. The system was sold in the United States under its original name by Docutel/Olivetti of Dallas. AT&T and Xerox bought rights to rebadge the system as the AT&T PC 6300 and the Xerox 6060 series, respectively. (AT&T owned 25% of Olivetti around this time.) The AT&T 6300, launched in June 1984, was AT&T's first attempt to compete in the PC compatible market. It was also available in France as the PERSONA 1600, built by LogAbax. Versions The initial 1984 US version named AT&T 6300 came with either one or two 360 KB 5.25" floppy drives; a hard disk was not offered. In Europe, Olivetti launched a 10 MHz version: the Olivetti M24 SP, announced in November 1985, a contender for the title of "highest clocked 8086 computer" as its processor was the fastest grade of 8086-2, rated for a maximum speed of exactly the same 10 MHz. To support this, the motherboard now featured a switch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hard Drive
A hard disk drive (HDD), hard disk, hard drive, or fixed disk is an electro-mechanical data storage device that stores and retrieves digital data using magnetic storage with one or more rigid rapidly rotating hard disk drive platter, platters coated with magnetic material. The platters are paired with disk read-and-write head, magnetic heads, usually arranged on a moving actuator arm, which read and write data to the platter surfaces. Data is accessed in a random-access manner, meaning that individual Block (data storage), blocks of data can be stored and retrieved in any order. HDDs are a type of non-volatile storage, retaining stored data when powered off. Modern HDDs are typically in the form of a small disk enclosure, rectangular box. Hard disk drives were introduced by IBM in 1956, and were the dominant secondary storage device for History of general-purpose CPUs, general-purpose computers beginning in the early 1960s.
