Computers store data in lots of places. The HDD (Hard Drive Disk) stores memory permanently. The RAM (Random Access Memory) stores memory in a faster to use format but it cannot store data once power to it is lost. (I.E., turning the computer off) The CPU (Central Processing Unit) stores information quite like RAM, only with higher efficiency) The GPU (Graphics Processing Unit) stores everything required to see what your computer is doing through the monitor. Disks (Floppy/Compact) store information like the HDD only the information is portable, Floppy disks are inefficiency, break easily and are very old technology whereas CDs (Compact disks) are newer, faster, have more storage and last longer. USBMSDs (Universal Serial Bus Mass Storage Devices) are little sticks you can plug into a computer that function like Floppy Disks and CDs but have MUCH more storage space and are a different shape to FDs and CDs. There are also a few other kinds of data storage device usable by PCs nowadays.

What two distinct things must a computer be able to store?
Computerised information systems have to store programs and data.
What is difference between RAM and harddisk?
RAM means Random Access Memory. It store data temporaly. It called primary storing device. The two main forms of modern RAM are static RAM (SRAM) and dynamic RAM. Harddisk is the primary storing device within the computer. It can store data permanently (until you delete the data). It can retain data even after the computer itself "dies". Therefore, one harddisk can be switched to a different computer of similar size. An external harddisk can store huge amounts of data within a desktop unit. It can store data permanently (until you delete the data).
What different types of memory can hold a computer program?
two types of memory i.e. primary and secondary memory.
What is the difference between download and save?
Download means to move data from one computer to another. Save means to store or write out data to a storage device like a disk on the computer that currently has it in memory. You can download a file from another computer on internet and then save it to the hard disk on your computer -- these are two different actions.

0 (Zero) and 1 (One) are the two digits used in Binary code, which is the lowest form of code usable by a computer.

Data and command.
How do sync cables work with devices that are plugged into a computer?
Sync cables are used to synchronize data on two devices. One of the items are usually a computer/laptop, the other is a small mobile device such as an MP3 player, cellphone or PDA. These cables are used to help store and organize large amounts of data on a computer than a smaller device.
Which two computer components can be used to permanently store data?
non volatile (ie permament storage after power down) storage components are a DVD/CD or Hard Disk Drive
Data and instructions in a computer are classified as?
two-state or binary system
What are the types of tax software?
When you go searching for tax preparation software, there are two places where you should go: your friendly computer store and the World Wide Web. Many tax programs are in CD-ROM format that can be bought from computer shops.
Why do we need secondary storage devices?
As a backup for saving files. You may lose data if it is not saved to secondary storage. When you turn off your computer, any unsaved data is lost. That is why you need to save it to something like a USB key.
What is buffer in operating system?
Buffering is temporary storage while a computer completes current tasks. Two typical places where buffering occurs are:- (1) Downloading from the internet... the connection may be able to deliver data faster than the computer can process it. (2) Printing... since printers work relatively slowly in relation to the computer, the computer can create a 'queue' of documents waiting to be printed.
