digital design computer basics

what is the computer divided up into?

input and output devices

what is input

things that send info into your computer

what is output

things where info is coming out from your computer

what are examples of input devices?

mouse, microphone and webcam

what are examples of output devices?

the monitor, little printer, and speakers

what is the outershell of the computer?

a case and its primary function is to keep the inside of the motherboard/computer nice and safe from the things that are on the outside

what are some facts about the outershell?

it was vents on the front and back of the motherboad that keeps the system cool

what is power supply?

take power from the electrical outlet and spread it out all over your computer system and gives power to all individual parts

expansion slots

allows to connect peripheral video cards

CPU (Central Processing Unit)

comes in hertz, always processing info; the brains of the computer which oversees all of its functions

what 2 companies make CPUS

AMD and Intel

heat sink

helps keep your cpu cool

What is a fact about RAM?

the more storage capacity your RAM has the more things you can do at the same time: multitask

what is the graphic card

converts image data to a form that can be viewed on a monitor

CMOS (complementary metal-oxide semiconductor)

acts as an internal battery to ensure info is still stored when the computer is turned off; for BIOS battery: retains your date, time and vial settings

fan

cools the internal components

hard disk

primary storage medium for most programs and documents

IDE (integrated drive electronics controller)

interfaces the hard drive, floppy disk drive and CD-ROM

motherboard

main circuit board which all other components are connected

ports

interfaces for additional components

RAM (random access memory)

allows quick access to recently viewed data

ROM (read only memory)

fireware used in almost all Electonics

BIOS (asic input output system)

stores info when your computer is turned off

AGP (Accelerated Graphics Port)

high speed connection from graphics card to computer

OS (operating system)

not really a hardware but software which allows basic functioning of the computer

real time clock

synchronize all computer components

whats on the right side of the motherboard?

there are 6 serial ATA or SATA ports on the board. It connects hard drive/cd-rom or dvd-rom drives

red e serial ata

designated for hooking up external drives

pin configurations

used for USB cables and most of the time it comes with ribbon cables

speaker

used to give you notifications from the BIOS: also tells you if there is problems

IDE controller

for older style hard drives or cd rom drives

jumper

works in conjunction with your battery and BIOS

16 x pci express slot

used by graphic card

dual channel ddr2 memory

supports up to 800

what does power LED and hard drive LED have in common

they have a polarity, so you have to get those right or LEDs in front of the case so they dont show up or turn on

what is a bit

comes from binary digit 0 or 1 and it is located by the letter B and its always capitalized

what is bits for seconds

indicates the rate on which info can be transferred

groups of 8 bits and provide a more readable representation of data such as character encoding schemes
