Computer Security Many commercial software packages are designed with computer security features that control who can access the computer. These types of access controls use a process called identification and authentication. Identification verifies that the user is a valid user‚ and authentication verifies that the user is who he or she claims to be. Three common methods of authentication are remembered information‚ possessed objects‚ and biometric devices. With remembered information‚ a

Assignment 1: Computer Archtecture Intro to Info Technology – CIS 106031VA016-1144-001 Professor John Murnane May 4‚ 2014 Von Neumann Architecture Von Neumann architecture is a stored program architecture with no differentiation between data and instruction memory. Both the data and instruction reside on a single chip. The concept of no differentiation between data and instruction memory is accurate‚ but existing on one chip has nothing to do with it. Most computer memories

size[edit] Microcomputers (personal computers)[edit] Microcomputers are the most common type of computers used by people today‚ whether in a workplace‚ at school or on the desk at home. The term “microcomputer” was introduced with the advent of single chip microprocessors. The term "microcomputer" itself is now practically an anachronism. These computers include: * Desktop computers – A case and a display‚ put under and on a desk. * In-car computers (“carputers”) – Built into a car‚ for

PUTER REVOTHE REVOLUTION OF COMPUTER By Feri Agus S‚ Indonesia A computer is a programmable machine. The two principal characteristics of a computer are: it responds to a specific set of instructions in a very good manner and it can perform a pre-recorded some list of instructions or programs. From those basic characteristics‚ the computer has grown up to five generations and its functions have extended. The first computer was invented in 1940 with a tube form and had many deficiencies.
