Introduction to ComputersCris Paulo Hate, CpEFaculty MemberComputer Engineering DepartmentTechnological Institute of the Philippines Quezon City1Intended Learning OutcomesDefine the term, computer, and describe the relationship between data and informationDescribe the role of each element in an information systemDescribe the five components of a computer: input devices, output devices, system unit, storage devices, and communication devicesDistinguish between system software and application software

2Topic OutlineWhat is a Computer?Elements of an Information SystemThe Components of a ComputerComputer Software3What is a Computer?A computer is an electronic device, operating under the control of instructions stored in its own memory, that can accept data, process the data according to specified rules, produce results, and store the results for future use. 4Information Processing CycleComputers process data into information.ProcessInputOutputDataInformationBlock Diagram of a Computer SystemData is a collection of unprocessed items, which can include text, numbers, images, audio and video.

Information conveys meaning and is useful to people; processed data.5Elements of an Information SystemDataHardwareSoftwarePeopleProceduresThe hardware must be reliable and capable of handling the expected workload. The software must be developed carefully and tested thoroughly. The data entered into the computer must be accurate. Most companies with mid-sized and large computers have an IT department. IT Staff should be skilled and up-to-date on the latest technology; and they should also train users so that they understand how to use the computer properly. Finally, all the IT applications should have readily available documented procedures that address operating the computer and using its programs. 6The Components of a ComputerInput DevicesOutput DevicesSystem UnitStorage DevicesCommunication Devices7The Components of a ComputerInput Devicesany hardware component that allows you to enter data and instructions into a computer.

Output Devicesany hardware component that conveys information to one or more people.

8The Components of a ComputerSystem Unitis a case that contains electronic components of the computer that are used to process data.

Three (3) main parts inside the system unit ProcessorMotherboardMemory9The Components of a ComputerStorage Devicesrecords (writes) and/or retrieves (reads) items to and from storage media; often function as a source of input because they transfer items from storage to memory.

Communication Devicesa hardware component that enables a computer to send (transmit) and receive data, instructions, and information to and from one or more computers or mobile devices.

10The Hardwarecomponents of a Computer

Excerpted from Discovering computers, your interactive to the digital world. Australia: Cengage Learning.11Computer SoftwareSoftware, also called a program, is a series of related instructions, organized for a common purpose, that tells the computer what task(s) to perform and how to perform them.

System software consists of the programs that control or maintain the operations of the computer and its devices. System software serves as the interface between the user, the application software, and the computers hardware.

Application Software consists of programs designed to make users more productive and/or assist them with personal tasks.12Computer SoftwareSystem Software- consists of the programs that control or maintain the operations of the computer and its devices.
