Computers cannot express their full power if they are not connected to a network or cannot talk to each other. A network is actually two or more computers connected using some type of network cable. Computers can share files, access common disk drives, and share printers.
Laptop computers, officially known as notebooks, are a smaller version of a desktop. The big difference is, of course, that laptops are designed smaller and lighter to be portable. Laptops have motherboard, memory, hard drive and keyboard as desktops have, but they have everything almost embedded into the motherboard. They’re computers on the go, which makes them ideal in many work situations where you’re away from the office or as a supplement to your standard desktop system.
Buying a laptop works just like buying any computer; at the moment of buying it, users should make the same considerations that are made when buying desktops.
Information security is based on the psychology of fear. Users are afraid that their systems get breached and developers are under pressure to fix a problem that requires time and more than one person to get it done.
The truth of the matter is that network security is costing millions of dollars a year, also because of the ineptitude of companies like Target that allowed intruders to steal the credit card information of its customers.
Two types of storage are in every computer: temporary and permanent. It’s like our brain: we can remember lots of things right away or we can use long term storage. But unless you commit the information to memory, you had better write it down, which is permanent storage. In a computer, temporary storage is provided by memory, or RAM (Random Access Memory). The more RAM your computer has, the smoother it operates and the more information you can “play” with at once.
Memory is also responsible of giving extra speed to your computer and, most of all, more stability. Nowadays, almost all computers are sold with at least 8GB of DDR3, which allows users to browse fast on the Internet and easily download and upload files to the cloud.
All computers must have at least one hard drive. At the moment of selecting hard drives two factors come into play: capacity and rpm speed. You want to ensure that your new computer has enough hard drive storage for all your computer software as well as all the stuff you create and store there.
Most computers are now typically sold with a 500 GB hard drive, which allows users to store thousands of pictures and videos and a large collection of Itunes songs.
It seems obvious to say that computers need at least one hard drive. However, if the hard drive is very large, a good tip is to partition the main hard drive in two parts: the main part for the system files and the other part for storage. This way if the computer crashes, it is always possible to retrieve the files from the second part of the hard drive.
