Cyber Defense Tip: Remote Backup Services
In Cyber Defense Tip: Back up your data, I mentioned a number of ways you can physically back up (make a copy of) your computer's data to protect it. I also recommended that you store your backup disks and devices away from your computer in case there's a disaster.
Another option for backing up and storing your data that ensures its safety is to use a remote or online backup service. For a fee, these services will automatically back up your computer's data without hardly any effort required from you.
Even though these services cost money, they come with a lot of benefits. You don't have to deal with buying disks or keeping track of your backup data since these virtual services are conducted through the Internet. They will also backup your computer on a regular basis so that you don't have to worry about remembering to.
If you want to use a remote backup service, just make sure you use one that has up-to-date encryption technology and secure machines to protect your data from theft.

How Computers Work: The Basic Parts
Computers are a collection of hardware and software components working together to do a variety of tasks. The basic external hardware parts of a computer are usually a system unit or tower, a monitor, a keyboard and a mouse.
All the processes of the computer happen in the tower, everything else is a peripheral, meaning it is not necessary but helps you use the computer. Keyboards and mice allow you to give the computer commands, and a monitor lets you see the results of those commands. Other peripherals include printers, scanners, external hard drives, speakers, modems, and routers. Some newer computers combine the tower and the monitor into one single piece to save space, and laptop computers incorporate all the components into one portable piece.
Inside the tower, the main hardware components are the motherboard and CPU (Central Processing Unit, the “brain” of the computer), hard drive, memory, video and sound cards and disk drives. Some mechanical parts are inside, too, like a fan to keep things cool, a heat sink, and a power supply.
Each of these components has a specific task to perform, and they all work together to operate the computer. Any of these components can break and cause your computer to malfunction, too. In the next couple of months I'll be going into more detail about some of these components to help you understand how they work and how problems with them can affect your computer.
