The AGC was one of the earliest uses of integrated circuits, and used core memory, as well as read-only magnetic rope memory. The astronauts were responsible for entering more than 10,000 commands into the AGC for each trip between Earth and the Moon. At a cost to computer makers of roughly $700, the ASR-33 Teletype is originally designed as a low cost terminal for the Western Union communications network. Throughout the 1960s and ‘70s, the ASR-33 was a popular and inexpensive choice of input and output device for minicomputers and many of the first generation of microcomputers. Software used for database management-the management of a collection of interrelated facts-handles data in several ways.

In this course, we use Microsoft's Excel spreadsheet application software. Everything you do on your computer will rely on both hardware and software. For example, right now you may be viewing this lesson in a web browser and using your mouse to click from page to page. As you learn about different types of computers, ask yourself about the differences in their hardware.

For its January issue, hobbyist magazine Popular Electronics runs a cover story of a new computer kit – the Altair 8800. Within weeks of its appearance, customers inundated its maker, MITS, with orders. Bill Gates and Paul Allen licensed their BASIC programming language interpreter to MITS as the main language for the Altair. MITS co-founder Ed Roberts invented the Altair 8800 — which sold for $297, or $395 with a case — and coined the term “personal computer”. The machine came with 256 bytes of memory and an open 100-line bus structure that evolved into the “S-100” standard widely used in hobbyist and personal computers of this era.

If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. When talking about a computer or a "PC," you're usually referring to a desktop computer found in a home or office. An example of the back of a personal computer and brief descriptions of each connection is found on our computer connections page.

Compaq's success launched a market for IBM-compatible computers that by 1996 had achieved an 83-percent share of the personal computer market. Weighing 24 pounds and costing $1,795, the Osborne 1 is the first mass-produced portable computer. Its price was especially attractive as the computer included very useful productivity software worth about $1,500 alone. It featured a 5-inch display, 64 KB of memory, a modem, and two 5.25-inch floppy disk drives. The first advertisement for a microprocessor, the Intel 4004, appears in Electronic News. Developed for Busicom, a Japanese calculator maker, the 4004 had 2250 transistors and could perform up to 90,000 operations per second in four-bit chunks.
