Laptop computers are great portable offices, and as technology increases and speeds of computers increase, we are seeing battery life also increase and provide longer usage time with out the need to be “plugged in”. They are more fragile than desktop computers, so they tend to have a much shorter operational lifespan. Why a much shorter operational lifespan? Because you’ll be carrying it around with you from room to room or even country to country so the poor thing is bound to have a few accidents along the way.
Laptop computers generally have two main parts, a display screen housing hinged to a keyboard housing and come in all different weights, sizes, and speeds. They take up less space on the desktop and can easily be moved aside to make room for other endeavors.
Laptops are purchased for personal use, business use, or both and have built-in keyboards with a touchpad or a pointing stick for input and ease of use. Usually they run on a single main battery or from an external AC/DC adapter that charges the battery whilst also supplying power to the computer itself even in the event of a power failure. Inside are components which are similar to their desktop counterparts and perform the same functions, but are miniaturized and optimized for mobile use and efficient power consumption, although typically less powerful for the same price.
Do bear in mind that laptops are generally prized targets of theft, and theft of these can lead to more serious problems such as identity theft from stolen credit card numbers. Being vulnerable to theft means the possible loss of all data contained on them. Also of course, due to their small size and mobility, they are much harder to secure than desktop computers.
Laptop computers generally cost more than desktop computers with the same capabilities because they are more difficult to design and manufacture. Remember, they are great tools for teaching and learning.
Comfortable and useful on vacation, these machines are going everywhere these days. They are very popular information products today as they are light, compact, and convenient to carry around and may store voluminous information. So if you want or need one, then get one! But don’t let it out of your sight or it might just walk. Just use the common sense that you already have.
