Adams internal components for the technically illiterate
- 1. INTERNAL COMPONENTS FOR THE TECHNICALLY ILLITERATE
- 2. INTRODUCTION Computers are a rising form of technology we are using more of. This slideshow is to show how it works. It will teach you these things while keeping things simple for you non-technical people (if you are familiar with technical terms, I suggest you to an identical PowerPoint but with more detail for those who understand)
- 3. PROCESSORS A CPU (central processing unit) is like the brain we humans have. Every computer has it. It takes in things we do on the computer like a click on a mouse and it processes it. For example if the answer for 1+2 was needed, then this question would go through the processor to give the answer of 3. The CPU size is measured in bits. Speed of CPUs are measured in Mega Hertz, this means how fast it processes information.
- 4. MEMORY ROM (read only memory) is memory that cannot be edited or modified. It can only be read or watched. There are times this can be modified, but only slowly and with difficulty. RAM (random access memory) is memory that can be edited and modified by anyone. It is randomly accessed by anyone Flash memory is a portable memory device that stores memory you want to use in multiple places EPROM- This is like ROM, but can be erased or re-modified to have a different purpose.
- 5. ADAPTER CARDS PCI- (Peripheral Component Interconnect) This connects between computers and peripherals like SATA cables. This uses parallel bus PCIe- (Peripheral Component Interconnect express) This is basically a smaller and faster version of PCI. This uses serial point-to-point
- 6. STORAGE CONNECTORS SATA (Serial Advanced Technology Attachment) is a standard that uses a serial link to connect drives. PATA (Parallel Advanced Technology Attachment) Is a Standard that connects hard drives and optical drives and uses a parallel signalling technology. SCSI (parallel interface supporting multiple devices on one cable.
- 7. INPUTS Touchscreen lets you take all your commands away from the keyboard and mouse and moves that all to your fingers, to touch the screen. Graphics tablets work like touchscreens, but are in tablet form Games controllers are like keyboards, but are restricted to over a dozen buttons and are meant to be gripped by the hand Microphone takes in voice Keyboard takes inputs of letters
- 8. OUTPUTS A printer is a device that puts what has been typed into a document on a computer into paper A monitor is a device that outputs what is currently happening in the computer, and is viewed by the future Speakers are devices that output sound that is happening inside computers
