...Main article: History of laptops Alan Kay with "Dynabook" prototype The Epson HX-20As the personal computer became feasible in the early 1970s, the idea of a portable personal computer followed. A "personal, portable information manipulator" was imagined by Alan Kay at Xerox PARC in 1968,[6] and described in his 1972 paper as the "Dynabook".[7] The IBM SCAMP project (Special Computer APL Machine Portable), was demonstrated in 1973. This prototype was based on the PALM processor (Put All Logic In Microcode). The IBM 5100, the first commercially available portable computer, appeared in September 1975, and was based on the SCAMP prototype.[8] As 8-bit CPU machines became widely accepted, the number of portables increased rapidly. The Osborne 1, released in 1981, used the Zilog Z80 and weighed 23.6 pounds (10.7 kg). It had no battery, a 5 in (13 cm) CRT screen, and dual 5.25 in (13.3 cm) single-density floppy drives. In the same year the first laptop-sized portable computer, the Epson HX-20, was announced.[9] The Epson had a LCD screen, a rechargeable battery, and a calculator-size printer in a 1.6 kg (3.5 lb) chassis. Both Tandy/RadioShack and HP also produced portable computers of varying designs during this period.[10][11] The first laptops using the flip form factor appeared in the early 1980s. The Dulmont Magnum was released in Australia in 1981–82, but was not marketed internationally until 1984–85. The $8,150 ($18,540 today) GRiD Compass 1100, released in...

Johnson EDITORS’ NOTE The purpose of this chapter is to provide an introduction to the fields of human resource management (HRM) and information technology (IT) and to the combination of these two fields into human resource information systems (HRIS). The history of the field of HRM and the impact of computer technology on HRM will be covered, as well as the advent of using a human resource information system and the subsequent effects on both HR and IT professionals. The different types of HR activities will be discussed as well as the different types of information systems used in HRIS. A central focus of this chapter is the use in managerial decision making of results and reports from an HRIS. The development of the HRIS field has been seen to have a significant impact on the emergence of strategic human resource management (Strategic HRM), as is discussed in this chapter. This first chapter will lay the groundwork for the remainder of this book, and, consequently, it is important to understand thoroughly the concepts and ideas it presents. This chapter contains definitions for a number of terms in common use in the HRM, IT, and HRIS fields. (Note that a glossary defining these terms is also provided at the back of this book.)

Algorithms In Computer Science

...Abstract—Algorithms are commonly perceived as a difficult subject, which is quite an irony as they have a fundamental role in computer science. Failure to master this subject will inhibit students’ capabilities as they advance to higher levels. Algorithm visualization, as an effort to overcome the problem, has been growing towards gameful visualization recently that is presumed to be able to engage learners longer and more intensely. However, integrating algorithm visualization, game elements, and instructional design is not a trivial task as it requires a careful design. Hence, a conceptual model of how algorithm learning instructions, algorithm visualization, and gamification improve learning outcomes was developed. While instructional design...
