The first multimedia computer

In 1992, Tandy Radio Shack introduced the M2500 XL/2 and M4020 SX. These were the first computers released with feature the MPC standard.

The MPC stands for Multimedia Personal Computer that was developed in 1990. It has the ability to execute programs, which connect video, audio, animation, and graphics. In 1992, Radio Shack introduced the first personal computers that support MPC specification. Nowadays, all modern computers that provide the facility of multimedia, they all are MPC compliant. The three types of MPC standards are available: MPC, MPC2, and MPC3. The requirements of MPC2 and MPC3 are described below:

Requirements of MPC 2

  • 4 MB of RAM
  • VGA Display.
  • Intel 486SX 25 MHz processor
  • 2x CD-ROM drive

Requirements of MPC 3

  • 8 MB RAM.
  • MPEG Support.
  • A processor of Intel Pentium 75 MHz
  • 4X CD-ROM drive.
  • Hard Drive of 540 MB

The concept of first Apple computer

Apple introduced its first Apple computer, Apple I (Apple 1) that was sold for $666.66. In 1976, Steve Wozniak developed the computer kit, and the computer had 4 kb of memory and a 6502 8-bit processor. The size of memory could be expanded to 8 or 48 KB by using expansion cards. Still, a display, power supply, keyboard, and case to be operational is needed by a kit, although Apple 1 contained a fully assembled circuit board.

The first laptop or portable computer

When was the first computer invented

In September 1975, the first portable computer, IBM 5100, was introduced with included a 1.9 MHz PALM processor, a five-inch CRT display, a tape drive, 64 KB of RAM, and its weighted 55-pounds.

In April 1981, a computer Osborne I, was introduced by Adam Osborne, which is considered to be the first portable computer or laptop. The computer was designed with essential features that offer benefit to users, such as two 5 1/4″ floppy drives, a 5-inch display, 64 KB of memory, ran the CP/M 2.2 operating system. Furthermore, the cost of this computer was $1,795 and weighed 24.5-pounds.

Later in 1984, the IBM portable was introduced by IBM PCD (PC Division) that included 30-pounds weight, and it was the first portable computer. In 1986, the PC Convertible computer was announced by the IBM PCD that was its first laptop computer, which included 12-pounds weight. Finally, the first notebook with an integrated CD-ROM, the IBM ThinkPad 775CD computer was introduced by IBM in 1994.

The concept of first personal computer

In 1975, the term “personal computer” was created when Ed Roberts introduced the Altair 8800. he created. Although, the KENBAK-1 is considered by many people to be the first personal computer that was first released for $750 in 1971. The computer took input and produced output data on the basis of the series of switches with the help of turning on and off a series of lights.

When was the first computer invented

In 1973, the first microcomputer, the Micral computer, was introduced by André Truong Trong Thi, a Vietnamese-French engineer, along with Francois Grenelle, which was considered the first microcomputer. It used the Intel 8008 processor, and its initially cost was $1,750.

The concept of first workstation

The Xerox Alto is considered to be the first workstation that was introduced in 1974. For its time, it was an innovative computer that contained a fully functional computer, mouse, and screen or a display. The computer worked like most computers today that uses icons and menus, windows as an interface for its operating system. On 9 December 1968, Douglas Engelbart demonstrated the different functionalities of a computer’s in Mother of All Demos. Additionally, the Xerox Alto computer was never sold. Also, on 15 November 1971, the first microprocessor, Intel 4004, was introduced by Intel.

The invention of first commercial computer

The Z4 was the first commercial computer developed by Konrad Zuse in 1942. On 12 July 1950, it was sold to a mathematician of the Swiss Federal Institute of Technology Zurich (Eduard Stiefel).

The first computer company

In 1949, the first computer company was founded by John Mauchly and J. Presper Eckert, which was the Electronic Controls Company. Later, the company name was changed from Electronic Controls to Eckert-Mauchly Computer Corporation (EMCC). Also, under the UNIVAC name, it released a sequence of mainframe computers.

Later in 1950, the ERA 1101 or UNIVAC 1101 was the first computer to store and execute a program from memory and delivered to the United States government for the first time. Furthermore, the first commercial scientific computer 701 was introduced by IBM to publicly on 7 April 1953.
