The Kinds Of Computers There are essentially 4 categories of Computers
Servers • One “main-mast” server • Holds huge amounts of information • Usually the center of a network • Maintains integrity of attached/detached network computers • Hold a little bit of data for each computer • Controls the entire infrastructure • Sometimes can be connected to via a Remote Desktop Connection

Laptops • A Laptop is… • A portable computer • Smaller than a Desktop • This makes its limiting factor weight and size: • Less capabilities for larger and better components • More fragile • Less upgrade capability • Does not run off of a continuous AC power supply • A device that connects to the internet via wireless adapter/card • Usually combines mouse, keyboard, and monitor
More Did You Know? • An Adapter is a device that connects to a computer to give it extra functionality: • An Internet Connection • A RJ-45 Connection (Wired Connection) • Some extra hardware connection • A Router is a device that intercept wireless pings (connection attempts) and (upon connection) transfers data to and from the connected device. • Connection to the “Internet” can be achieved in the following ways: • Wireless Adapter Router Internet • RJ-45 Connection Router or RJ-45 Outlet Internet • Dial-Up Internet • Dial-Up Modem (allows for greater speed) Internet • Wireless DeviceWireless Tower Internet
Portable Devices • Any device that utilizes basic input commands and gives out a result (output). • Types of Portable Devices: • Cell Phones • MP3 Players • PDA’s • Walk – and - Talkies • Calculators • Etc. • Some of these devices can access the internet but others cannot: • To have internet: Must have internal or external internet adapter • Most Common: Cell Phones
