Software

Software
All materials associated with computer operations other than the actual machinery (the hardware). Essentially, software is a set of instructions for a computer, installed via a variety of media, including CD-ROMs, discs or the Internet, or created and installed manually in the computer, using the keyboard. Most software is grouped into two categories of programs— system software and application software.

Computers and Architecture

Computers and Architecture
To realize an example of architecture, the object must be described. However, this in itself is insufficient—the process of realizing the object must itself be supported. It is in both these dimensions that computers have been of benefit in the practice of architecture in the 20th century. The use of computers in architectural design has been motivated by a number of factors and driven by others, and has come to reflect the evolution of practice through the last half of the 20th century.

Computer Forensics

Computer Forensics
‘‘Computer forensics’’ is a generic term that refers to the search, recovery, and preservation of digital evidence found on information systems while investigating criminal or civil cases. Information systems include any number of stand-alone or networked computers and other electronic devices, including portable media such as cell phones, PDAs, flash drives, CDs, DVDs, pagers, video games, MP3 players, and so forth. As a law enforcement, private investigation, and scientific discipline, computer forensics began during the early 1990s as personal computers (PCs) became popular among business and residential users. The misuse of PCs to violate acceptable use policies, violate computer crime laws, or harm people in other ways led to the onset of computer forensics and advancements within this field. Law enforcement in particular needed policies, procedures, and tools to identify, collect, and preserve digital evidence of various types of cybercrimes increasingly being committed by criminals.

Computer

Computer
Computer is a device that processes information with astonishing speed and accuracy. Computers process information by helping to create it and by displaying it, storing it, reorganizing it, calculating with it, and communicating it to other computers. Computers can process numbers, words, still pictures, moving pictures, and sounds.
