1) The client/server network is a network that uses centrally administered computers known as servers, this enables resource sharing between the other clients on the network. Now the peer to peer network is a network in which every computer can communicate directly with every other computer. Every computer on the peer to peer network has no authority over the other. However, each computer can be configured to share only some of its resources and keep other nodes from accessing certain information

using different examples. Some people believe the term to mean another way of describing IT (information technology), others use it to mean any computing service provided over the Internet or a similar network; and some define it as any bought-in computer service you use that sits outside your firewall. As you can seem, there is no straightforward definition for the term and therefore best way to understand it is to learn about how it works. The main point of cloud computing can be summed up with

mobile device, uploaded to a database that can be accessed by the doctor’s office. Storing vital sign stats on mobile devices is light years ahead of having a person physically take those vital have to enter them on a chart and then enter them into a computer system. The mobile technology also saves time by allowing instant access to the data instead of waiting hours. Patients are able to take advantage of the new smartphones and can monitor their own vitals and have a digital record they can share

simply stores data into a "memory" location and the data magically appears on some connectors external to the computer. Similarly, to input data from some external device, the CPU simply transfers data from a "memory" location into the CPU; this "memory" location holds the value found on the pins of some external connector. An output port is a device that looks like a memory cell to the computer but contains connections to the outside world. An I/O port typically uses a latch rather than a flip-flop

information from a database as per the requirements. DBMS is an intermediate layer between programs and the data. Programs access the DBMS, which then accesses the data. There are different types of DBMS ranging from small systems that run on personal computers to huge systems that run on mainframes. There are a lot of database software manufacturers out there and a wide range of prices, sizes, speeds and functionalities. At the lower end of the scale are personal database software products like Microsoft

1. A microprocessor is a computer processor that incorporates the functions of computer’s central processing unit (CPU) on a single integrated circuit (IC), or at most a few integrated circuits. The microprocessor is a multipurpose, programmable device that accepts digital data as input, processes it according to instructions stored in its memory, and provides results as output. 2. A digital signal processor (DSP) is a specialized microprocessor (or a SIP block), with its architecture optimized
