Inside the System Unit CPU and RAM

Microprocessor Basics  Computers can understand only 1s and 0s – each 1 or 0 is a bit  8 bits is a byte IT190 Foundations in Information Technology KilobyteKB1024 bytes~1 thousand bytes MegabyteMB1024 kilobytes~1 million bytes GigabyteGB1024 Megabytes~1 billion bytes TerabyteTB1024 gigabytes~1 trillion bytes PetabytePB1024 Terabytes~1 quadrillion bytes ExabyteEB1024 Petabytes~ 1 quintillion bytes ZetabyteZB1024 Exabytes~1 sextillion bytes YottabyteYB1024 Zetabytes~1 septillion bytes

RAM vs. ROM What is the difference? IT190 Foundations in Information Technology

Memory RAMROM  Random Access Memory  Volatile  SRAM, DRAM, CACHE  Chips  Read Only Memory  Non-Volatile  PROM, EPROM, EEPROM  Motherboards  Graphics Cards IT190 Foundations in Information Technology

Memory vs. Storage What’s the difference? IT190 Foundations in Information Technology

Memory Memory - RAMStorage  Running applications  1+ GB  Not saved  Dynamic – changes fast  One silicon piece  Stored applications  100+ GB  Saved  Static – slower changes  Contains moving parts IT190 Foundations in Information Technology

External Connectors There are six primary types of connectors  Din  USB  FireWire  DB  RJ  Audio

Plugs, ports, jacks, and connectors Computer plugs Computer jacks Computer ports

FireWire, DB Connectors, RJ connectors, audio connectors

USB vs. Firewire USB 2.0FireWire  1.5 Mb/s 12 Mb/s 480 Mb/s supported  USB controller (host) required  Cable up to 5 m  Up to 127 devices  Hub topology  100 Mb/s 200 Mb/s 400 Mb/s supported  Peer to Peer networking – no host computer  Cable up to 4.5 m  Up to 63 devices  Daisy Chain topology IT190 Foundations in Information Technology

Soft Skills  Active Listening – is passively participating in a conversation where you focus on what the customer is saying.  Some of the benefits of active listening include: Quicker capturing of data and symptoms. Improves understand of problem.  Active listening moves the focus from the technician’s problems to the customer’s problems. IT190 Foundations in Information Technology
