Blu-ray Disc – an optical disc storage medium, looks like a CD but has much greater storage space.

C Drive, where your programs are run from and operate. C Drive is like the engine of your car. DO NOT delete any folders unless you know what you are doing, otherwise you could cause your computer not to run at all and you would need major repair work, which could easily cost hundreds of dollars. I recommend that you create a separate drive for your personal items, documents, photos, files. That’s another subject.

CD/DVD player slot/port-this is where you put the cd/dvd to play music or install a new program.

CD-R (Compact Disc-Recordable) – an optical compact disc which you can write on only once.

CD-RW (Compact Disc-Rewritable) – an optical compact disc you can write on many times.

CD-ROM (Compact Disc Read-Only Memory) – a pre-recorded optical disc which contains music or video.

Cords:

Yellow cord-the thick cord to connect to the router

Black cord-a usb cord connecting to mouse

Green cord-the cord connecting to the speakers you can hear your music

Black power cord: same as an electrical cord to connect your toaster to the call

CPU (Central processing unit) – the part of a computer that executes the instructions of a computer program.

“Desktop” This is the “picture” or screen you see when you first turn on the computer-you will see “icons,” little boxes for different programs-click an icon and it opens a document or a program.

Hard drive – a storage device with metal discs with magnetic surfaces, typically called the “C” drive, typically where your (untouchable!!!) programs are found. Your computer may also have an “E” or “F” drive for storage and backup of files and data.

Hardware – the physical parts of a computer.

Keyboard-where you type, with all the symbols, letters, numbers, etc.

Monitor: the screen where you see everything.

Motherboard – the central printed circuit board (PCB) in computers which contains many of the crucial components of the system and connecting to peripherals.

Mouse – a pointing device that is moved on the mouse pad to select actions on your computer. The left mouse button is used to execute or take an action; the right button is used to find drop down menus of actions you can take. If there is a middle “button” it is a scroll button you use to go up and down a number of files/programs.

Optical disc drive – a disk drive that uses laser light to read or write data to or from optical discs. It uses a “needle” like a phonograph needle to “read” or play the data. CDs, DVDS and Blue Rays are optical discs.

Peripherals: electronic devices other than the computer

Ports: slots where you can connect/plugin to the computer or other peripherals. See the picture of the side of the laptop above.

Touchpad: This is the rectangular pad below the space bar used to move the cursor and make selections just like the left or right clicking of the mouse.

USB connector-this connects from any electronic device like a smart phone, to a laptop or desktop. The top part of the USB is an open connector. See below-small cable head between my fingers.

USB port and cord: this is an electrical connector/plug for the computer or peripherals (other electronic machines).
