Today’s session we will review: Hardware/Software Managing Windows Opening & Closing Programs Parts of the computer Startup/Shutdown

What is a Computer?

What is a Computer? A general-purpose machine that processes data according to a set of instructions that are stored internally either temporarily or permanently.

Basic Parts? The computer and all equipment attached to it are called hardware. The instructions that tell it what to do are called software.

Hardware The hardware is the part of the computer you can touch and see.

Hardware The Monitor is the display screen, similar to a television screen. The Computer, tower or case is the heart of the system.  This is a box that contains all the parts that make the computer work. The Keyboard is what you type on, similar to a typewriter. The Mouse is the small hand held device that attaches to the computer.  It may have two or three buttons.  The mouse is used to move the cursor (pointer) on the computer screen.

Hardware The Printer is a device that puts what you have created on to paper. The Scanner similar to a color photocopier is a device that captures pictures or documents, so that they can be seen or used on the computer. The Laptop also known as a notebook computer is a small personal computer designed for mobile use. A laptop integrates all of the typical components of a desktop computer, including a display, a keyboard, a pointing device (a touchpad, also known as a track pad, or a pointing stick) and a battery into a single portable unit.

Hardware A Floppy Disk (sometimes just called a “disk”) looks like a plastic card that can be put into a slot in the front of the computer.  These disks hold information and can be used to exchange information between computers. This type of data storage is archaic and obsolete. A CD-ROM is very similar to a stereo’s CD player.  It not only plays music but can also retrieve information stored on CD's. It is also available in other formats such as DVD-ROM.

Software Software is a part of the computer you cannot touch. Software consist of computer programs and procedures that perform some tasks on your computer. Computer software is divided into three basic types.

Software System software Operating System is the base program on a computer is considered system software.  It tells the computer how to work or operate.  The operating system also allows you to load other programs that do specialized tasks on to your computer. (ex. Windows XP and Vista)

Software Application software Application software allows you to accomplish one or more specific (non-computer related) tasks. Such as computer games for entertainment or Microsoft Word for typing.

Software Programming software Programming software provides tools to assist a computer programmer in writing programs and software.

How to Start?

Simply, press the corresponding button to power up your computer. Turning off your Computer When powering down your computer, check to make sure all programs are closed and files are saved. Properly remove any connected devices, such as Mp3 players and USB Flash Drives. Click “Start” then “Shutdown” to power off your computer.
