Input Devices : All devices that sends instructions to the machine. An example for input devices are the classic Mouse and Keyboard. Professor: Nabil Elmjati IB100 Introduction to computer Sciences

Output Devices : An output device is the mean used to receive data from a computer. Current examples of output devices are the Screen, Printer, and speakers. Professor: Nabil Elmjati IB100 Introduction to computer Sciences

The Motherboard: The motherboard is the main circuit board of a computer and is also known as the mainboard or logic board. The motherboard contains the connectors for attaching additional boards. Professor: Nabil Elmjati IB100 Introduction to computer Sciences

The Microprocessor (CPU): The Microprocessor, also known as the central processing unit (CPU), is considered the brain of a Computer and where most calculations take place. Professor: Nabil Elmjati IB100 Introduction to computer Sciences

RAM : RAM (which stands for Random Access Memory) is a small circuit board that contains millions of transistors. A Computer can access, read from, and write to the RAM. Professor: Nabil Elmjati IB100 Introduction to computer Sciences

Storage Media: The Hard Drive (HDD): Also known as the hard disk, the hard drive is the main storage unit of a computer, and allows the storing of files, folders and programs. The hard drive allow the user to create, delete and modify data on it. Professor: Nabil Elmjati IB100 Introduction to computer Sciences

Fun Fact: Professor: Nabil Elmjati IB100 Introduction to computer Sciences

USB Flash Drive:  A small, portable flash memory card that plugs into a computer's USB port and functions as a portable hard drive.  The first commercial USB drive offered 8MB of space, but current drives have reached 128GB of free storage and are getting cheaper every day. Professor: Nabil Elmjati IB100 Introduction to computer Sciences

- Serial Port (COM):  Also known as a RS 232 port  New Computers do not come equipped with a COM port anymore. This port was used commonly for connecting a mouse, phones and other networking devices. Professor: Nabil Elmjati IB100 Introduction to computer Sciences

- Parallel Port (LPT): Almost obsolete, this port was mainly used to connect old Printers. Professor: Nabil Elmjati IB100 Introduction to computer Sciences

- USB Port:  A standard in all Computers today.  Allows connection of all kinds of devices, from Printers, input devices to external hard drives. Professor: Nabil Elmjati IB100 Introduction to computer Sciences

- VGA Port:  A blue port used to connect the PC Monitor.  Currently being replaced with DVI and HDMI Professor: Nabil Elmjati IB100 Introduction to computer Sciences

- DVI Port: A white port that is replacing the VGA. DVI allows a computer to connect to a high definition monitor or TV. Professor: Nabil Elmjati IB100 Introduction to computer Sciences

- HDMI Port: Like the DVI, an HDMI allows the computer to connect to newly released monitors and current High Definition Television. One major advantage of HDMI is the ability to transfer both HD Video and Audio using one cable only. Professor: Nabil Elmjati IB100 Introduction to computer Sciences

1-6-1 Operating system: The Operating System, also known as the OS, is the most important, and crucial type of Software found on a Computer. Professor: Nabil Elmjati IB100 Introduction to computer Sciences

1-6-2 Application Software: An application Software (also known as an application, a program, or an App), is any program that can be run on an operating Systems. Professor: Nabil Elmjati IB100 Introduction to computer Sciences

1-6-3 Device Drivers: A program that controls a device. Every device, whether it be a printer, disk drive, or keyboard, must have a driver program. Professor: Nabil Elmjati IB100 Introduction to computer Sciences

1-6-4 Binary Numbers:  The transistors in Computers only understands two states (which are represented by two numbers):  On: when the current goes through it and we represent it with number 1.  Off: when there is no current going through it and represent it by the number 0. Professor: Nabil Elmjati IB100 Introduction to computer Sciences
