Basics on Networking
A network is a number of computers that are designed to hook up to each other and to run together by transferring information and data across cabling. A network allows the computers on the network to move and access files through the network, and to give access to other machines. A network can range in size from a basic peere-to-peer version between two computers at home to the biggest network going, the Internet with an estimated 100,000,000 plus computers connected onto the system.
Networking and Internet safety
The Net is about as safe as a dark alley. Maybe there are badguys lurking in the shadows; maybe there aren't. But you aren'tdefenseless. There are two types of trouble on the Net: threats to security andthreats to privacy. Potential security bogies include viruses contained in file downloads, rogue ActiveX controls that can crash your computer, malicious email attachments, holes in Java that let hackers read data on your hard disk, and a host of other weaknesses in your Internet software. Despite all the press reports, the odds are against your becoming the random victim of a hacker. You're much more likely to run into a virus, but installing and using antivirus software should take care of this. Avoid opening email attachments from people you don't know, and use good judgment about paying with credit cards on the Web: if you don't know that the company is reputable or don't know where to find it in the real world, then keep your card in your wallet.
