FC: Digital Communication System (DCS) By: Alexis Williams

1: Hardware Hardware is the components that you can actually touch on the computer.(Example: Keyboard, mouse, monitor....) Hardware is IPO. Which stands for Input, Processing, And Output. There is also Storage. Input devices are keyboards and mouses. The input devices is what put the information into the computer. CPU is the central processing unit. It what processes the information you input. Output devices are monitors and printers. Output devices put out what you have created.

2: System Software System software runs the computer. It is the boss of the computer It boots up and shuts down the computer. System software is the Operating System (OS).

3: Application Software Application Software are the programs and games on the computer. Application are the icons on the computer. Some examples of application software are: Microsoft Word- Makes Documents PowerPoint- Creates Presentations Publisher Excel Micro-Type Application Specific is used to teach something or to do something. (Examples: Micro-Type, games, Quick Books, Email, Virus Protection, and Internet.)

4: Commercial Software Commercial Software has to be purchased to be used. It is copyrighted software. This means that the person that copyrighted it has control of it. A person has to ask the owner before copying it. It is the safest software.

5: Shareware Shareware is software that can be used for a trail period. mostly it is used for students. It is copyrighted software as well. It is safer than freeware.

6: Freeware It is free software. It is copyrighted but the owner has chosen to give it away free. It is the second least protected software from viruses.

7: Public Domain Software It is controlled by the public. It is not copyrighted. It is free to use, copy, and distribute. It is the least safest from viruses.

8: Viruses Viruses are computer programs or codes created to destroy or damage a computer. The different types of viruses are Bombs, Worms, Trojan Horse, Phage, and Hoax.

9: Types of Viruses Bombs are viruses that have a timer and are set to go off at a certain time. Worms are viruses that go through files and destroy them slowly by eating them away. Phage are viruses on PDA's. Trojan Horse is a virus that is made to look good and beautiful but really it's a virus. Hoax look like something bad but really it's not. It's a trick to make you ruin you're computer. Anti-Virus is used to protect your computer for viruses. Encryption is a special code that only the sender and the reader can read so it can't be hacked and read.

10: Types of Viruses (cont.) Ethics are what you should do on the computer. Hackers are people who get into you're files to steal money and important information about you. Piracy is the illegal copying and distribution software. Passwords are personal codes used to keep people from getting into you're personal stuff.

11: Speech Recognition There are different kinds of voice or speech "engines" that take the sounds of your voice and match it with words. Speech recognition works when a you speak into a microphone connected to your computer. The sound-card or multimedia chip and the speech engine processes your speech. Every person that us speech recognition programs have their own unique "voice profile" that is separate from others. You choose your voice profile when you begin. Then over time the computer learns more about your voice and how you speak. Like a child, it learns what words you say and can correct it immediately.

12: Speech Recognition (cont.) Continuous speech recognition application allows a user to dictate text fluently into the computer. These new application can recognize speech at up to 200 words per minute. While theses systems do give the user system control they are not yet hands-free. Depending on the speed of your computer there are continuous speech, normal speaking speed and discrete speech, slight pauses between each word, versions available.

13: Speech Recognition (cont.) Continuous speech is more natural but it requires a more powerful computer to processes the information. Most modern speech recognition programs are continuous. many people, especially ones that have learning disabilities prefer discrete system. Speech recognition allows a user to use his/her a]voice as an input device. Voice recognition may be used to dictate text into the computer or to give commands to the computer, such as opening programs, pulling down menus, or saving work.

14: Speech Recognition (cont.) Some why to learn speech recognition: It increases productivity It helps avoid injury or overcome a handicap It improves writing skills It improves reading skills It improves speaking skills

15: Keyboarding Keyboards are a standard type of input on computers. They allow people to input information into computers, use keys for short cuts to a program or tool, get out of programs, delete information quickly, print quickly, and a million other things. Keyboards can be on cellphones too. Some phones have standard keyboards and others have qwerty keyboards. some other phones and devices have touchscreen device, such iPod touches and PDA's.

16: Computer Mouse A computer mouse is a pointing device that functions by detecting two-dimensional motion relative to its supporting surface. a mouse consist of an elements of an object held under on of the user's hands. the computer mouse is one of the most common input devices. A computer mouse senses motion, clicks, and send information to the computer SO it can respond appropriately. a mouse today is connected by a USB cord to the computer. A ball is inside a mouse. It touches the desktop and rolls when the mouse moves. There are two rollers inside the mouse. one

17: Computer Mouse (cont.) There are two rollers inside a mouse. One roller is oriented so that it detects motion in the X direction. The other is oriented 90 degrees to the first one so it detects motion in the Y direction. the rollers connected to the shaft, and the shaft spins a disk with holes in it. On either of the disk there is an infrared LED and an infrared sensor. A board processor chip reads the pulse from the infrared sensors and turns the binary data into data the computer understands. The chip sends the binary data to the computer through the mouse's cord.

18: USB Flash Drives A USB Flash Drive is a small, portable flash memory card that plugs into a computer's USB port and functions as a portable hard drive. It can be taken to another computer, plugged into it USB port, and open up a document, spreadsheet, powerpoint, or etc. some of it's advantage is that it's small and can be taken anywhere because it's pocket sized. it also have no moving parts and still can hold a considerable amount of memory. Some disadvantages are that it can only hold so much memory, it can't function by itself, and it can only store memory and transfers it.

19: USB Flash Drives (cont.) USB flash drives can also be called thumb drives, jump drives, pen drives, key drives, or USB drives. Sometimes the free memory can range from 256MB to 128 GB+. The first flash drive was created by IBM in 200, and could only hold 8 MB of memory. USB connectors provides an interface to host computers. USB mass storage controllers implements the USB host controller. NAND flash memory chips store data. Crystal Oscillators controls the devices data output.

20: Notebooks Notebook Computers typically weigh less than 6 pounds and are small enough to fit easily in a briefcase or other compartment. they come with battery packs that allow you to work and run them without the computer being plugged into an outlet. But they must be recharged every few hours. Notebooks are more expensive then laptops because they are smaller and more compacted.

21: Tablet PCs Tablet PC's are generally referred to as a laptop equipped with a touch screen that is operated with a stylus or finger tip instead of a keyboard or mouse. Tablet PCs are often used where normal notebooks do not provide the particular function needed. they have capacitive technology, which sense the touch of finger with no pressure required. it has a digital palm recognition technology. this prevents accidental contact from disturbing the pen's input. They are readable in sunlight. They are light weight, but more expensive because they are so small and touchscreen.
