A Brief Guide to Laptop Computers

A computer is an integrated machine which is able to execute certain sets of instructions automatically. It can store and retrieve data, manipulate them using certain software, and make calculations. Modern computers are able to do virtually all kinds of tasks, thanks to the software that they run on. There are different parts that make up a computer, but the most essential part is the central processing unit (CPU). The CPU manages the overall operation of the computer.

A computer can either be a desktop unit, which is used by single-user operation or a minicomputer, which is usually used by multiple users. A minicomputer has a wider memory space and a faster processor than desktop computers. Desktop computers use certain programs to operate, while minicomputers use software to do their job. These computers are generally cheaper than desktop ones and are a good buy if you are looking for an economic computer.

There are many different types of computers. PCs are small single-user units, which are a primary platform for home computers. Laptops, or personal computers, are much larger and used by businesses. Supercomputers, which have the capabilities of many smaller personal computers, are the largest and most expensive type of computer. The price ranges between these different types of computer are vast and it is difficult to determine which one is right for you.

A laptop computer is an excellent choice for a single user who only uses the notebook version of the personal computer. The notebook computer lacks the power of a minicomputer, but the mobility is much greater. Notebook computers are also a good choice for a business user who needs the same capacity and speed as a desktop model but who does not need the extensive memory space, fast processor speed, and graphics card power that a desktop model computer can provide. Laptop computer buyers also appreciate the price point of these machines. Desktop models are more expensive than notebook computers, but prices have been continually falling on desktop models in recent years, making them a great choice for most consumers.

Many laptop computers are available with extended warranties, either for a specific period of time or for the life of the machine. These warranties may cover mechanical failures, software malfunctions, and even accidental liquid damage. Extended warranties cover all of these bases, and may be less expensive than buying a new computer altogether. Before buying a laptop computer, be sure to research the extended warranty so that you will know what it covers.

Notebook computers are much smaller than desktop computers, making them often called mini desktops. Although they are not as big, they have all of the same features, including the keyboard, mouse, monitor, and video card. They are also usually equipped with at least one CD/DVD drive and one external port for connecting the computer to a personal computer or a USB drive. Laptops have many of the same features and functions as desktop computers, and many of the same ports and accessories, so laptops are often called mini desktops as well.
