Internal components for the technically iliterate Liam Winter
Introduction Computers are a rising piece of technology we are using more of. It is time to we all knew how it works. This powerpoint will teach you these things while keeping things simple for you non-technical people (if you are sure of many technical terms, I may refer you to the same powerpoint but made smaller for you to understand)
<ul><li>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 processes it. For example if the answer for 2+2 was needed, then this question would be go through the CPU to give the answer of 4. </li></ul>Processors
<ul><li>ROM (read only memory) is memory that you can’t do anything to except to read it or watch it.
RAM (random access memory) is memory that anyone can do things to. It randomly lets through anyone.
Flash memory is a memory device that can go with you almost anywhere, it keeps memory you want to use in multiple places. </li></ul>Memory
Memory <ul><li>EPROM- This is like ROM, but can be completely gotten rid of. </li></ul>
Adapter cards PCI- (Peripheral Component Interconnect) This connects between computers and cables that connect to other devices (e.g. printer) 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
Storage connectors <ul><li>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 signaling technology.
SCSI is a parallel interface supporting multiple devices on one cable. </li></ul>
Inputs <ul><li>Touchscreen lets you touch the monitor and still allows you to do things like a mouse and keyboard would
Graphics tablets work like touchscreens, but are smaller and can be carried
Games controllers are like keyboards, but are restricted to over a dozen buttons and are meant to be gripped by the hand
