What are input devices? List some examples
An input device is any hardware device that sends data to a computer, allowing you to interact with and control it.
Examples:
-keyboard
-mouse
-microphone
-bar code reader
-graphic tablet
-game controller/joystick
-scanner
-touch screen
What are output devices? List some examples…
An output device is a piece of computer hardware that receives data from a computer and then translates that data into another form. Examples include:
-monitors/projectors
-headphones
-speakers (audio)
-sound card
-video card
-printer
-GPS devices
What is a graphics card?
The purpose of a graphics cards is to render graphics. Without a graphics card, your computer can not display any information, let alone function how you need it. Basically, expansion card which generates output images to a display.
Where is the graphic card located?
it is typically located in the expansion slot closest to the CPU (inside, there is the motherboard)
Other possible names for graphics card?
A video card, display card, graphics card or graphics adapter
What is processing speed?
A computer’s processor clock speed determines how quickly the central processing unit (CPU) can retrieve and interpret instructions… Processing speed, which will enable video data and frame rates to be maintained, the processing of images such as morphing and distorting as well as animations
What is the CPU?
The CPU is the Central Processing Unit, basically the “brain” of the computer. CPU is a small but mighty computer chip found on top of the motherboard in your PC. Your computer’s CPU calculates and interprets instructions while you’re surfing the web, creating documents, playing games, or running software programs
What is frames per second? Distinguish the slowest and fasted frame rate.
Frame rate, then, is the speed at which those images are shown, or how fast you “flip” through the book. It’s usually expressed as “frames per second,” or FPS. It is measure the number of pictures that are shown in one second on a display device. Slowest is 60fps (slow motion) and normal is around 24-30fps.
What are storage devices? Provide some examples.
A piece of computer equipment on which information can be stored. Examples include memory cards (storing media and data files), floppy disks (used in the past for storing computer data and programs), hard disk drives (stores and retrieves digital data), optical disks, pen drive (USB), RAM/ROM
What are other storage devices?
-USB (Universal Serial Bus (USB) is an industry standard that establishes specifications for cables, connectors and protocols for connection)
-Blu-Ray
-DVD
-CD-ROM
-SD Card
What is the importance of RAM?
Stands for Random Access Memory. Has a RAM chip of its own.
Volatile memory (when the power goes out the contents of the RAM is cleared)
Needs power to maintain the contents
It is where the “data” that is retrieved from secondary storage is held prior to processing
What are optical storage devices?
Optical storage is any storage type in which data is written and read with a laser. Typically, data is written to optical media such as compact discs (CDs) and digital versatile discs (DVDs)
Common optical storage includes:
CD-A (for CD audio)
CD-ROM
CD-R
CD-RW
DVD (digital versatile disk)
What is volatile memory and non-volatile memory?
Volatile memory is a type of storage whose contents are erased when the system’s power is turned off or interrupted. An example of volatile memory is RAM (random access memory).
Non-volatile memory (NVM) or non-volatile storage is a type of computer memory that can retain stored information even after power is removed. ROM (Read Only Memory) is the most common example of non-volatile memory.
What is resolution?
The resolution refers to the digital file/film/other images holds. The higher the resolution, the more detailed the image holds, with a larger file size. It won’t be blurry or grainy. In simpler words, it is able how much pixels it holds e.g height x width (1 megapixel = 1 million pixels).
What is a colour depth or bit depth
A computer graphics term for “bitmap images”
