Personal computer types
actual personal computer can be generally classified by size and chessis / case.The chassis or case is the metal frame that serve as the structural support for electronic components.Every computer system requires at least one chassis to house the ciruit board and wiring.The chassis also contain slots for expansion boards.If you want to insert more board then there are slots,you will need an expansion chassis,which provides additional slots.There are many variation on these two basic types.
Then more the portable computers that are that are computer small enough to carry portable computers includes notebook computer,hand held computer,palmtops and PDAs.
Tower model:
The term refer to computer in which the power supply,motherboard,and mass storage devices are stacked on top of each other in a cabinet .This is in contrast to desktop model ,in which this components are housed in more compact box.The main advantages of tower model is that their are fewer space constraints,which makes installation of addition storage devices easier.
Desktop model:
computer design to fit comfortably on top of desk,typically with the monitor siting on top of the computer.Desktop model computers are board and low ,whereas tower model computers are narrow and tell.Because of their shape,desktop model computers are generally limited to three internal mas storage devices.desktop model design to be very small are sometimes reffer to as slim line models.They are typically larger and more powerful than other types of personal computers.Desktop computers are made up of separate components.The main component,called the system unit,is usually a rectangular case that sits on or underneath a desk.Other components,such as the monitor,mouse,and keyboard,connect to the system uniy.

5 different types of personal computers :
Notebook computer
An extremly lightweight personal computer.Noteook computer typically weigh less than 6 ounds and are small enough to fit easily in a briefcase.Aside from size,the principal difference between a notebook computer an personal computer is the display screen.Notebook computer use a variety of techniques,known as flat panel technologies,to produce a lightweight and non bulky display screen.
The quality of notebook computers are display screen varies considerably.in terms of computing power ,morden notebook computers are nearly equivalent to personal computers.They have the same CPUs,memorey capacity,and disk drives.

laptop computers
A small portable computer-small enough that it can sit on your lap.Nowdays,laptop computers are more frequently called notebook computers.Laptop computers can operate on batterries,so you can take them anywhere.Unlike desktops laptop combines the CPU,screen,and keyboard in a single case.The screen folds down onto the keyboard when not in use.
Small notebook PCs are small ,affordable laptops that are designed to perform a limited of tasks.They are usually less powerful than a laptops,so they are used mainly to browse the web and chech the e-mail.
Subnotebook computers
a portable computer that is slightly and smaller than a full sized notebook computer.typically subnotebook computers have a smaller and screen, but are otherwise equivalent to notebook computers.
Hand-held computer
A portable computer that is small enoufgh to be held.although of their small keyboards and screen.

Hand-held computer
A portable computer that is small enoufgh to be held.although of their small keyboards and screen.
The most popular hand-held computers are those that are those are specifically designed to provide PIM function,such as a calender and address book.
Palmtop
A small computer that literally fits in your palm.compared to full-size computers,palmtops are severely limited,but they are practical for certain function such as phone books and calenders. palmtops that use a pen rather than a keyboard for inoput are often called hand-held computers or PDAs computers .Because of small size,must palmtop computers do not include disk drives.However,many contain PCMCIA slots in which you can insert disk drives,modems,memory and devices,palmtops are also called PDAs,hand-held computers and pocket computers.
PDA
Short for personal digital a hand held device that combines compouting,telephone/tax,and networking features.Unlike portable computers,most PDAs pen-based,using a stylus rather than a keyboard for input.This means that they also incoporate handwritting recognition featues.
