Computer system level 5 and 6

What is an operating system: An operating system is the most important software that runs on a                                                           computer. It helps with the computers memory, processes and all of                                                         its software and hardware.It also allows you to communicate with the
                                                  computer with out knowing how to speak a computers language.                                                             Without an operating system the computer is useless. 

                   What is Firewall:   A security system consisting of a combination of hardware an software                                                     that limits the exposure of a computer or computer network to attack,                                                      commonly used on local area networks that are connected to                                                                  the internet
       
               What is Anti Virus: Anti-virus software is a program or set of programs that are designed to                                                   prevent, search for, detect, and remove software viruses, and other                                                        malicious software like worms, adware, and more. 


What is a malware Protector: Malware refers to software programs designed to damage or do other                                                     unwanted actions on a computer system. 


A tablet computer is a mobile computer with a touchscreen display, circuitry ans battery in a single unit. They usually feature on-screen, pop up virtual keyboard for typing. Tablets may include physical buttons for basic features such as speaker volume and power, and ports for networks communications and battery charging. There are many different types of tablet makes such as Acer, Archos, AUSUS, Coby, Dell, Lenovo, Samsung, Sony, Toshiba and many more. the most popular would be the IOS (Apple), Windows and Android tablets. There are many uses for different brands of tablets, Android offer the most free aps. Standards are improving following enhancements to the play store and security settings, Android can access Google play. Apple IOS apps must be authorized which means less free apps. IT departments will help with the set up (through this it is easier if you are using a suite of Apple products).

Computer Hardware. 9.3

Friday 1st May 2015

LO: To understand what parts make a computer and how they work.


Motherboard: The motherboard is an circuit board that holds all the computer components together.Such as the CPU, RAM ,power supply and hard drive plug into the motherboard.This allows all the parts to create a fully functional machine. A computer would be useless with out a motherboard.

Sound Card: A sound card is a component with the ability to produce sound that can be heard through a device such as headphones or speakers. The computer doesn't need a sound card to function, but they include it on every machine anyway.

Video card: A video card is a PC component that is used to project a good quality image to be shown on display. It is attached to the motherboard and controls the images appearance on the screen.

Good and bad vector images




This is a good vector image because                                      no matter how much you zoom in it
 can never go blurry or have pixels.
A vector picture can only have basic
colors that are made online. You can
find logos like this everywhere because
it is really popular and  can be seen on
a billboard for example. Apple is a
brand which is  range from 10-70+
year old, it is a high quality image and
can be made smaller so that is can go
on to a back off a phone.


              This logo is a well known logo, everyone knows 
             it and it is really popular. The logo is really plain
             and simple and memorable people can remember it
            easily. It this it kind of represents their logo in a 
            way that it is sporty just like their products. I think
           that it is a unique product and not a lot of people
           have the same kind of logo.      
                                                                              
                                                                           
                                                                  Logo doesn't just target one audience. It target everyone :)

Vector Graphics

Key words:
-Input.
-Output.
-Constructed.
-Hardware.
-Software.
-Vector Image.
-Vector Graphics.

Task 1:
Input: An input devise is a hardware that humans can use to communicate with the                                          computer.
Output: An output devise is something that you can receive information from.

Hardware:
-Keyboard (input)
-Computer mouse (input)
-Monitor (output)
-Printer (output)

Task 3: (Level 3)
Software used to create vector graphics is sometimes referred to as object-based software. The most common vector formats include; (Adobe Illustration) ,(CorelDRAW), (Computer Graphics Meta file), (Shock wave Flash)......

Task 2: (Level 4)
Vector Graphics are made in graphic packages and consists of shapes called objects. You can change the color,shape, size....of each object separately. A vector graphic is scalable which means it does not lose the quality of the image when you enlarge it.

Level 5:
The disadvantages of a vector graphic is it cannot reproduce different shades of colors like the bitmaps and and all the continues tones through. out the picture.

3 types of hardware:
-Keyboard
-Mouse
-Computer
3 types of software:
-PowerPoint
-Firework
-Adobe Illustrator

Vector graphic showing enlargement without pixelationLevel 6:
A vector graphic is different to a bitmap because no matter how much you zoom in and out of the picture it will never turn in to
a pixel image. Vector images are mostly used for logos and billboard because the images can be zoomed in so much that there are  no pixels and it is concentrated on the curves color and edges.

Level 7:
There are two vector graphic called DrawIt and Xara Xtreme. DrawIt is an easy-to-use, powerful vector drawing application designed for a Mac. It features entirely non-destructive editing, live filters, powerful vector tools, a standard collection of basic shapes and a clear and intuitive interface. Xara Xtrreme is the second editor that you can use to create vector graphic images. It is a powerful, general-purpose graphics ptrogram foe Unix platforms, including Linux, FreeBSD and (in development) Mac OS X. Formerly known as Xara LX, it is based on Xara Xtreme for Windows, which is the fastest graphics program available. Its latest version is 0.7.
I think that the DrawIt is the best vector
