How Must You save at School?

When it comes to saving files or just saving pictures there are tons of little device were you can save stuff on for example:

USB

Cloud

Flopper disk

Gmail

Student file

On you can save work and work on it later. For the USB you can save files and then plug it in on a different computer and keep on working. On Cloud you can save more stuff than files you can save apps and more on any computer. For the flopper disk its more old school because before they invented USB they used a flopper disk. For a Gmail you can save a bunch of stuff and then go on your gmail on someone else's computer and continue working.

Hardware• Mother board- A mother board is the board who

bring all pieces of a computer together. Everything connects to the mother board.

• Hard disk drive- A hard disk drive I s a device where it holds the most data in a computer.

• Modem- A modem is a were you get wifi from and without it you would not be able to surf the web.

• Video card- a video card is an expansion card that allows the computer to send graphical information to a video display device such as a monitor or projector.

• Sound card- a sound card is a device where it lets sound messages come out of headphones or speakers.

Hardware part 2• Cd-rom :drive The data on a compact disc (CD) is stored on the disc as a

series of tiny, almost microscopic bumps and lands. Each of these bumps represent a piece of information, though no specific information is directly stored.

• Motherboard: It is the soul reason your computer works. Without it, you just have a box. Everything your computer does runs through this... the Processor, the video card, the fans, the CD drives, the HDD, the RAM.

• Soundcard: A soundcard is part of your hardware. It can be on-board, that means integrated into your main board, or it can be external. It generates sound, that you can hear by usually using some low-quality 3,5 mm-stereo jack speakers or headphones. The sound can be music or special effects of films or games.

• Modem: The modem on a computer translates digital signals into an analogue 'noise', and transmits it down a telephone line. This is received by another modem at the other end, which captures the signals, and converts them back into data.

• Ram memory: Your ram assists with, it's like your short term memory, anything that you're doing on your computer at that precise time temporarily gets stored in your ram so you can access it more quickly than if it was stored on your hard drive.

Measurement terms
