A database management system (DBMS) is a collection of software application package with some computer programs that are used to store, create, fetch, modify and extract the information from the database. Each DBMS system has some set of rules and pre-defined paradigm on which each database is working. There are many different types of DBMSs, ranging from small systems that run on personal computers to huge systems that run on mainframes or Solaris servers. Some of the example of DBMS is 1

computer’s memory, this basically means the steps necessary to provide ways of allocating portions of memory to programs at their request and feeing it up for reuse when no longer needed (Stallings, 2012). This management system is critical to the computer system. In order for memory management to multi-task it must utilize and deal with the six requirements of memory management. The first one of these requirements utilized is the relocation of memory. Relocation of memory pertains to programs that

system administrator's life simpler and easier. Fortunately, the protocols are so flexible that they can be implemented either together or separately depending on the size and configuration of your enterprise network. So whether you have 5 or 5000 computers in your network this would be justifiable action because of the following reasons: Looking up IP addresses can be a nightmare if you have more than a couple to remember If you have network-enabled printers, unless you lock the address, it will change

Question 1: What is the nature of Information? Explain how individuals interpret data to become information. Answer: Data that is (1) accurate and timely, (2) specific and organized for a purpose, (3) presented within a context that gives it meaning and relevance, and (4) can lead to an increase in understanding and decrease in uncertainty, is called an information. Information is valuable because it can affect behavior, a decision, or an outcome. For example, if a manager is

It is because DMA is an essential feature of all modern computers. It allows devices to transfer data without subjecting the CPU to a heavy overhead. Otherwise, the CPU would have to copy each piece of data from the source to the destination, making the CPU unavailable for other tasks. This situation is aggravated because access to I/O devices over a peripheral bus is generally slower than normal system RAM. With DMA, the CPU gets freed from this overhead and can do useful tasks during data

Von Neumann was a founding figure in computer science.[49] Von Neumann's hydrogen bomb work was played out in the realm of computing, where he and Stanislaw Ulam developed simulations on von Neumann's digital computers for the hydrodynamic computations. During this time he contributed to the development of the Monte Carlo method, which allowed solutions to complicated problems to be approximated using random numbers. He was also involved in the design of the later IAS machine. Because using lists
