REVIEW (INTRODUCTION.PPT)

• Course Objective• Entry level training in media and

technology communications• Class Rules and Expectations

• No food or drink. Maintaining your area.• Visible electronics will be confiscated• No cursing• Punctuality and participation• Being respectful of the equipment

• “How I Learn Best” Assignment

TODAY’S AGENDA: BASIC INFORMATION TECHNOLOGY VOCABULARY• Computer• Hardware • Motherboard• CPU and Memory• Peripheral Devices• Software• Operating System• Directories • Applications

OBJECTIVE

Getting to know the inside of your computer.

COMPUTER

We use them everyday, but what are they? What was the inspiration behind their invention?

A computer is a piece of technology based on the human brain.

HARDWARE VERSUS SOFTWARE

The hardware of a computer is its physical or permanent equipment (Body).

EXAMPLE: motherboard, CPU, memory chips, peripherals

Software is a set of instructions that directs the computer to accomplish a task (Thoughts).

EXAMPLE: Operating systems, Applications

A CD is hardware, but a file on a rewritable disk containing instructions is software. The software (program) might be on the disk today but erased tomorrow when a new program is written on the disk.

It is clear that the CD is permanent and the software is temporary.

MOTHERBOARD

The motherboard is the most complicated piece of equipment inside the computer.

Some of the items housed by the motherboard include:CPU (Central Processing Unit) RAM (Random Access Memory) Chips Cache Memory - controls memory access speed BIOS (Basic Input / Output System) Chip - controls basic hardware functions and power supply connections to provide electricity to the system components

MOTHERBOARD (BASIC)

MOTHERBOARD (ADVANCED)

CPU AND MEMORY REVIEW

Hardware = Body

Software = Thoughts

CPU (Central Processing Unit) = Brain

In addition to the CPU, the motherboard contains two kinds of memory chips: ROM (Read Only Memory) and RAM (Random Access Memory)

ROM chips have programming permanently stored on them however Flash ROM is rewritable.

CPU AND MEMORY

CPU AND MEMORY

RAM memory chips are installed onto the motherboard

They hold both data and programming instructions while they are being processed by the CPU.

ROM chips contain permanent (long-term)memory whereas, RAM is temporary (short-term).

On the motherboard

Peripheral Devices

PERIPHERAL DEVICES

Peripheral devices connect to and communicate with the computer either internally or externally. Although they can attach to it, they are not part of the motherboard.

External peripheral devices communicate with what is inside the computer through cables attached to the case at a connection called a port.

PERIPHERAL EXAMPLES

Video card - a board inside the computer that controls the video display (monitor).

Keyboard - the primary input device of a computer.

Mouse - a pointing device used to move the cursor and make selections on the screen.

All non-wireless external peripheral devices communicate with the computer through cables attached at the ports.

VIDEO CARDS

PORTS

WALK THROUGHShow me a peripheral device and a port on your computer.

SOFTWARE

Software is a set of instructions written by programmers to instruct computers to perform specific tasks.

There are two types of programs: Operating systems (OS) and Applications (Apps).

Generally a computer has one OS and several applications.

SOFTWARE

OPERATING SYSTEMS (OS) AND APPLICATIONS (APPS)

Stored on the hard drive, the OS supports a computers basic functions such as scheduling tasks, executing applications and controlling peripherals.

Apps, also stored on the hard drive, execute user commands. They are software programs used to create files.

FILE NAMES

A file name has two parts: Filename – name you give your file Extension – appended letters the

computer uses to tell which app created the file

EXAMPLE: Word files use .doc or .docx.

HARDWARE

HARD DRIVE

A hard drive is a self-contained storage device with a read - write mechanism plus one or more hard disks, inside a sealed unit. It is the primary computer storage device.

The hard drive is a piece of hardware that stores the OS, Apps and files.

HARD DRIVES

Internal

External

DISCUSSION QUESTIONS

Give some examples of external peripheral devices.

What are ports used for?

Name the two types of programs? What do they do?

What types of information are contained on the hard drive?

DISCUSSION QUESTIONS

Give some examples of external peripheral devices.Mouse, Keyboard

What are ports used for?To connect external peripherals

Name the two types of programs? What do they do?OS – controls the basic functions of the computerApplications – executes user commands

What types of information are contained on the hard drive?

OS, Apps, Files (Long-term memory)

DIRECTORIES

DIRECTORIES

A directory is a table on the hard drive that contains a list of files that are stored on the disk.

The root directory is the first directory on the drive. On PC’s the root directory is C Drive “C:\” by default.

On Mac directories are shown are folders.

DIRECTORIES

There are other directories sometimes called subdirectories or child directories.

Any directory can have files and / or other directories listed in it.

You can organize your files by creating different directories and folders.
