Laptop computers are portable computers that are used to perform the same tasks as desktops but on a smaller scale. The term laptop carries with it the connotation that the computer should be carried around, although it could just as easily be placed on a table too. However, in most cases laptops have greater processing power and computing capabilities than desktops. A notebook computer is not necessarily a laptop although it is often referred to as one.
The term desktop computer is used to describe computers which are placed on the floor or on a desk. The term desktop assumes a more permanent role in the computing environment, just as the monitor takes up an elevated position on a desk.
The system on which the computer is based includes:
An Operating System (OS): Many vendors, especially those selling laptops and notebooks, offer portable versions of their desktop operating systems; however, it may be more cost-effective to purchase the full-blown version for use with a desktop.
A basic input/output (BIOS): Many laptops include a BIOS, which is the lower level program that runs when the computer is turned on. The BIOS provides basic set-up options such as displaying the time and date, configuring the serial port, and setting up keyboard and mouse. If no local hard drive has been installed, the BIOS must be set to format a slave drive before it can be used.

Laptops are smaller and lighter than conventional desktops. Desktop computers usually require at least a monitor and a keyboard and mouse, whereas laptops consist of all of these components within a single unit. There is no distinction between the monitor, the CPU, and other peripheral devices in a laptop. This makes it more convenient for the user, as there is no need to set them up. By contrast, a desktop computer occupies much more space. The need for an external monitor and other peripherals also means that setting up a desktop computer is more cumbersome and time-consuming than setting up a laptop.
Laptops resemble desktops in that they are designed to be used while they remain plugged into an external power source. This is because laptops are not designed to be able to operate for long periods off their internal batteries. They are generally equipped with a small battery that can last up to several hours, depending on the brand and the usage. When laptops run low on battery power, it is necessary for them to be plugged into an electrical outlet for charging. In many cases, the laptops will allow users to choose whether they want them to be charged or just run off of battery power. This feature is useful for people who have a lot of work to do on the laptops, but also need to use them away from an electrical outlet.
Netbooks are smaller than laptops and less powerful, but this does not necessarily mean that they are less capable than desktops. It is also a common misconception that netbooks are less expensive than laptops. However, this is often not the case. Netbooks usually have a lower resolution screen and usually don’t have as much storage capacity. That is why they are also known as ultra-portables . However, a netbook is not nearly as small as it looks. The screen size is relatively large and the weight of a typical netbook is between 2.5lbs to 9lbs depending on the specific model. [BACKGROUND]
Intuitively, it would seem that, because they are smaller and need less power, netbooks should be cheaper than bigger laptops. In fact, that is not necessarily the case. With laptops, it is possible to purchase a more expensive model with more features and higher resolution. There are no such options available with netbooks. [CRITICAL THINKING]
The term tablet PC is used to refer to computers that are sold as tablets but then can be used in a conventional manner. The iPad is the best-known example of this type of computer. Tablet PC’s are not specifically designed for people who want to perform specific tasks. However, their size and weight make them attractive for people who use their devices when traveling or for people who have weak hands or have physical disabilities. Their small size also makes them excellent tools for studying and reading . Tablet PC modems are also useful for people who travel a lot. The small size means that a large number of these devices can be carried easily, and the dual-mode technology means that a modem for a phone or broadband connection can be used even when the tablet PC is in airplane mode.
Entertainment tablets, on the other hand, are designed specifically for entertainment. While there are some exceptions (for example, some tablets have keyboards), most entertainment tablets have only one purpose: to play video games and other video-oriented applications. Entertainment tablets also include some applications designed for people who want to take notes while they are watching a movie.
Tablet PCs are often called “hybrids” or “convertibles.” They can use either wireless networks or wired networks, and they usually have both a touchscreen and a separate input device (such as a keyboard). Tablet PCs have become more common in the past few years. Tablets have become more popular for several reasons:
Since the first tablet PC was introduced in 2001, the technology has evolved and improved. These improvements have strengthened the advantages of tablet PCs, especially the weight and size advantages. In addition, the success of tablet PCs has encouraged other manufacturers to create similar devices.
Smartphones are mobile phones that are usually touchscreen and use the latest mobile operating systems. They usually provide Internet access and can be used as a personal digital assistant (PDA). Smartphones are also called cellular phones because they work with cellular networks. Some smartphones can function as a camera, camcorder and a music player. Most smartphones use the GSM technology, which means that they only work with SIM cards. Some use the CDMA technology which means that they can only be used in the network that uses that technology. Some smartphones support both technologies, which gives their users the chance to switch between networks.
