Unit 6 – Storage Devices & Memory Videos 1.06 and 1.08 covered Storage Devices and Memory. The 1st one covered all the different types of storage devices. It started with hard drives and went on to floppy drives‚ cd’s‚ dvd’s‚ solid state removable and tape drives. It also covered all the interfaces that can be used with them. The video also touched on power connections used to power up the different storage devices. Video 1.08 covered memory. It went through the two different types of memory

Secondary Storage Devices COMPUTER Compiled by Belieber9N Class - IX PROJECT Secondary Storage Devices As we all know that the main memory stores the data in a temporary manner which means all the data will be lost when the power goes off. To keep our data safe we use secondary storage devices. These are used for storing the data in a permanent manner so that all the data will remain stored whether the power is switched on or switched off‚ the power will never

Computer Storage Devices Storage devices are used in order to store various items such as programs‚ data and instructions. Storage was used as early as 1804 by hole punching paper cards in order to control machinery. Without storage‚ the computer programs and files that exist now would not be possible. There are many different devices used for storage today such as hard drives‚ floppy drives and CD-Rom drives. Hard drives come in all computers and are the main storage device. An average hard drive

Basic Input and Output Methods for VB Introduction So far‚ we have relied on GUI-based Input/Output By using VB controls For Data Input to our programs For Data Output from our programs: = Data Entry TextBox (our basic input tool‚ so far) CheckBox‚ OptionBox‚ etc = Data Displaying Label‚ message box ListBox However‚ we may also use Files for I/O These provide a means for long term storage of results. Using Files for Input / Output

Optical Storage Devices • An optical disk is a high-capacity storage medium. An optical drive uses reflected light to read data. • To store data‚ the disk’s metal surface is covered with tiny dents (pits) and flat spots (lands)‚ which cause light to be reflected differently. • When an optical drive shines light into a pit‚ the light cannot be reflected back. This represents a bit value of 0 (off). A land reflects light back to its source‚ Representing a bit value of 1 (on)

This refers to the way information is processed in a computers information management system. The information processing cycle consists of five specific steps: 1. Input – This is any kind of data- letters‚ numbers‚ symbols‚ shapes‚ images or whatever raw material put in to the computer system that needs processing. Input data is put into the computer using a keyboard‚ mouse or other devices such as the scanner‚ microphone and the digital camera. 2. Processing – This is the transformation‚ sorting

The operating system that I have chosen is a particular service operation: the realisation of a music concert. As every other organisation that produce goods or services‚ it has a precise operating system‚ composed by a range of inputs‚ a transformation process and a final output. INPUTS - We must distinguish between two different kind of resources: transformed resources‚ that are the resources treated and transformed in some way‚ and transforming resources‚ that are the resources that act upon

Activities Our thesis adviser discussed chapters 1 and 2. After discussing the chapters 1 and 2; some students find their respective groups for thesis. Our group‚ first find a Host Company for our System Proposal and that is NOLSEN CONSTRUCTION AND TRADING. Then we asked them if they have a SALES AND INVENTORY SYSTEM. The proponents interviewed the company‚ and we analyze their minor and major problem of the company. After we analyze the problems; we made the documentations for Chapters 1 and 2. Then we

IS HUMAN INFORMATION PROCESSING (HIP)? People are active‚ dynamic systems capable of great flexibility in the ways they choose to handle and transform information. From the HIP perspective‚ the human mind is understood as a system that processes incoming information from the environment. HIP is an abstraction of the set of processes involved in several aspects of human behavior including problem solving and decision making in both everyday and professional environments. This system can be described

Input devices 1.Keyboard In computing‚ a keyboard is an input device‚ partially modeled after the typewriter keyboard‚ which uses an arrangement of buttons or keys‚ to act as mechanical levers or electronic switches. A keyboard typically has characters engraved or printed on the keys and each press of a key typically corresponds to a single written symbol. However‚ to produce some symbols requires pressing and holding several keys simultaneously or in sequence. 2. Mouse In computing‚ a mouse
