nd sold by Tandy Corporation through their Radio Shack stores. The name is an abbreviation of Tandy/Radio Shack, Z-80 microprocessor. It is one of the earliest mass-produced and mass-marketed retail home computers.
Home computers were usually not electronic kits; home computers were sold already manufactured in stylish metal or plastic enclosures. There were, however, commercial kits like the Sinclair ZX80 which were both home and home-built computers since the purchaser could assemble the unit from a kit.
An electronic kit is a package of electrical components used to build an electronic device. Generally, kits are composed of electronic components, a circuit diagram (schematic), assembly instructions and often a printed circuit board (PCB) or another type of prototyping board.
The Sinclair ZX80 is a home computer launched on 29 January 1980 by Science of Cambridge Ltd.. It is notable for being the first computer available in the United Kingdom for less than a hundred pounds. It was available in kit form for £79.95, where purchasers had to assemble and solder it together, and as a ready-built version at £99.95. The ZX80 was very popular straight away, and for some time there was a waiting list of several months for either version of the machine.
Advertisements in the popular press for early home computers were rife with possibilities for their practical use in the home, from cataloging recipes to personal finance to home automation,but these were seldom realized in practice. For example, using a typical 1980s home computer as a home automation appliance would require the computer to be kept powered on at all times and dedicated to this task. Personal finance and database use required tedious data entry.
Personal finance is the financial management which an individual or a family unit performs to budget, save, and spend monetary resources over time, taking into account various financial risks and future life events. When planning personal finances, the individual would consider the suitability to his or her needs of a range of banking products or investment private equity, and insurance products or participation and monitoring of and- or employer-sponsored retirement plans, social security benefits, and income tax management.
Home automation or domotics is building automation for a home, called a smart home or smart house. A home automation system will control lighting, climate, entertainment systems, and appliances. It may also include home security such as access control and alarm systems. When connected with the Internet, home devices are an important constituent of the Internet of Things.
A data entry clerk is a member of staff employed to enter or update data into a computer system. Data is often entered into a computer from paper documents using a keyboard. The keyboards used can often have special keys and multiple colors to help in the task and speed up the work. Proper ergonomics at the workstation is a common topic considered.
By contrast, advertisements in the specialty computer press often simply listed specifications.If no packaged software was available for a particular application, the home computer user could program one—provided they had invested the requisite hours to learn computer programming, as well as the idiosyncrasies of their system. Since most systems shipped with the BASIC programming language included on the system ROM, it was easy for users to get started creating their own simple applications. Many users found programming to be a fun and rewarding experience, and an excellent introduction to the world of digital technology.
Computer programming is the process of designing and building an executable computer program for accomplishing a specific computing task. Programming involves tasks such as: analysis, generating algorithms, profiling algorithms' accuracy and resource consumption, and the implementation of algorithms in a chosen programming language. The source code of a program is written in one or more languages. The purpose of programming is to find a sequence of instructions that will
