What Is A Computer? l. A computer is an electronic device, operating under the control of instructions stored in its own memory. l Can accept data and process the data according to specified rules. l Produce results and store the results for future use. Page 6 10 10

What Is A Computer? (Cont. ) Collects data (input) Processing Produces information (output) Information Processing Cycle 11

Data vs. Information Data A collection of unprocessed items, which can include text, numbers, images, audio and video. Information Conveys meaning and is useful to people. Page 6 Figure 1 -2 12 12

Data vs. Information (Cont. ) l Hence, computers process data (input) into information (output). l Computer often holds data, information and instructions in storage for future use. l Instruction are steps that tell computer how to perform particular task. l Some refer to series of input, process, output and storage activities as information processing cycle. 13

Networks and the Internet A network is a collection of computers and devices connected together, often wirelessly, via communications devices and transmission media l i. e. satellites, cellular radio networks – wireless and hence no physical lines or wires. l Allow computers to share resources i. e. hardware, software, data and information – saves time and money. l Pages 10 - 11 Figure 1 -6 14 14

Networks and the Internet (Cont. ) A server manages the resources on a network, and clients access the resources on the server. This network enables three separate computers to share the same printer, one wirelessly. 15

Networks and the Internet (Cont. ) l Server In many networks, one or more computers act as a server. l Server controls access to resources. l l Client or workstation request resources from the server. Server vs. Client l Server ordinarily has more power, more storage space and expanded communications capabilities THAN Client. 16
