A single chip that contains all of the elements essential for any computer RAM / ROM CPU Input / Output Clock The area in the computer that temporarily holds data waiting to be processed RAM ROM Binary Code Bit RAM stands for Random Access Memory. It is the memory that holds your data as you manipulate (process) it. The data stays in RAM until you save it. RAM is volatile which means ‘temporary memory ROM stands for Read Only Memory. ROM contains the instructions the computer uses when it ‘boots up’. Because the data is ‘read only’, it can be read but not changed by the user. The data is not erased when the computer is switched off—the data is stored permanently. This is called ‘non-volatile memory’. Therefore, ROM is “permanent memory” Binary code is the language that computers use to communicate and process information. It is a coding system using the 0 and 1 to represent a letter, digit, or symbols in a computer or other electronic device Each 0 or 1 is called a bit. A bit is the smallest unit of information that a computer handles Byte A combination of eight bits is called a byte. One byte (8 bits) represents a single letter, symbol, or digit. Kilobyte Approximately one thousand bytes Megabyte Approximately one million bytes Gigabyte Terabyte Approximately one billion bytes Storage The place in the computer where data is held while it is not needed for processing Magnetic Storage Hard Drive A means of recording or saving data onto disks or tape by magnetizing particles External Hard Drive Floppy Disk Approximately one trillion bytes A mass storage device located inside the computer’s system unit (tower A hard drive that has its own separate case and sit outside of your computer’s system unit The floppy disk, once an icon of the computer age, is becoming obsolete Magnetic Tape Used by some businesses to backup and archive large amounts of data. Optical Storage Optical storage is the use of low powered lasers to save (burn) and read data from CDs and DVDs. CD DVD Electronic Storage Compact Disk Flash Drive A portable storage device that uses electronic storage and has an integrated USB port Memory Card A memory card is also known as a flash card, SD Card or memory stick Cloud Computing CD-ROM CD-R CD-RW Volatile Non-Volatile SaaS Photos and Videos, Services, Music, Documents, Calendar, Apps, Email, Data Storage and Backup Solid State Drive Electronic storage is the use of a chip to electronically save, erase or reprogram data. Examples of devices that use Electronic Storage: – SD (secured digital) Cards, Flash Drives, Solid State Drives Permanent, cannot be changed. Can be changed once, after it becomes read only. Can be changed and rewritten over and over. Temporary Memory, can be deleted Permanent Memory, cannot be changed. Software as a Service. No need to buy software and install it on your computer. SaaS allows you to rent access to software. Software is not installed on your PC—instead it is installed and run on computers operated by a software supplier It means that data is stored to devices via electronic semiconductors that are built from solid materials that have no moving parts Processing Processing means manipulating data.

The memory that stores data as you process it. Cannot store when the computer is turned off Stores the instructions the computer uses when it boots Temporary memory Permanent memory Refers to the speed of the processor (clock-speed) • Hertz represents how quickly the CPU can interpret instructions from the operating system and applications.
