Computer vs. smartphone
Many of the tasks handled by a computer may also be done on a smartphone or tablet. For a comparison, the computing power of a flagship smartphone generally rivals many laptops and desktop computers from about five years ago.
If you're deciding whether your next device upgrade should be a desktop computer or a mobile device, there are some key points to consider. Below is a chart that highlights some differences and similarities of each.
|If you want high performance, the CPU (central processing unit) uses a lot of electricity. The TDP (thermal design point) of a powerful desktop computer can range from 450 to 850 watts, or more. That's why high-performance computers use a standard wall plug. They also generate a lot of heat, often requiring large heat sinks (passive cooling), or fans or liquid cooling (active).
|Smartphones and tablets run on batteries, which means they have to use power as efficiently as possible. It's not feasible to provide the high, constant power to a device's CPU from such a small battery. Consequently, the newest smartphone will not give you as much power as a high-end desktop computer. Mobile devices are getting more powerful every month, but traditional computers always have the performance edge, due to consistent access to more electricity.
|Prices for a computer can vary widely depending on its capabilities, storage, and features. A mid-range computer usually costs between $500 and $800, and some of that cost can be offset if you already own peripherals, such as a monitor, keyboard, and mouse. More powerful computers will cost between $1000 and $2000, or more.
|The price of a smartphone can be financed month-to-month as part of a service plan from providers, such as Verizon or AT&T. Refurbished smartphones can be purchased on an e-commerce site like eBay or Amazon for $100-$300. However, new flagship smartphones can cost as much as $1300. Tablets, depending on size, usually cost between $200 and $600.
|Desktop computers can connect to a wide variety of monitors, allowing you to invest as much or as little as you want into that component. Most modern computer monitors are LCDs. Depending on their size, quality, and features, they generally cost between $100 and $500 (although some can cost more).
|Smartphone screens vary somewhat depending on the manufacturer and model. However, they always be smaller than a desktop or laptop as they generally range between four and seven inches.
|While laptop computers are usually light and portable by design, they can't compete with smartphones in this regard.
|Smartphones are lightweight and can fit in a purse or pocket. They are designed to be taken everywhere with you — the very definition of portability. A tablet won't fit into your pocket, but they're light and you can carry them in one hand.
|Consumer hard drive capacities already exceed many TB (terabytes) and they continue to increase in size. Today, even the most basic computer comes with a 250 GB (gigabyte). This applies to both desktop and laptop computers. However, some netbooks, such as the Google Chromebook designed primarily for working within a web browser, only offer 16 or 32 GB of space.
|Most smartphones and tablets come with between 16 GB and 128 GB of built-in storage. Sometimes, an expansion slot may be available for an additional memory chip providing removable storage. Smartphones and tablets have less storage capacity than a computer, and their components cannot be modified like a desktop computer's can.
|Desktop and laptop computers can run more powerful software than a smartphone or tablet due to their size, components, and less restrictive power requirements.
|While smartphones and tablets are getting more powerful every year, they still can't match a traditional laptop or desktop computer in terms of performance.
|Desktop computers generally come with Ethernet capability, either on the motherboard or a discrete NIC (network interface card). Most desktop computers require a peripheral device, such as a USB (universal serial bus) Wi-Fi adapter, to connect to wireless networks. Most laptops include both Wi-Fi and Ethernet networking as a standard feature.
|Smartphones and tablets can connect to Wi-Fi networks for Internet access. Also, smartphones can connect to a mobile data network; many tablets offer mobile data connectivity as well. Mobile data, however, comes at a premium and can be more expensive than a standard broadband connection.
|Operating systems designed for computers and laptops are full-featured. They are designed to use fast CPUs, large amounts of disk space, and high amounts of RAM (random-access memory). Also, they utilize the features of modern chipsets that are not available on most mobile devices.
|Mobile operating systems (Android and iOS) are specialized for a specific set of devices. By default, they don't offer you complete access to your system hardware (Administrator or "root" access). They also have stricter hardware requirements because the ecosystem of mobile apps and devices is strongly connected to specific hardware features. In other words, you can't run the newest apps on an older mobile OS (operating system), and the newest mobile OS won't run on a significantly older device.
|Data Entry and user input
|A computer uses a keyboard and mouse for input, which most users prefer based familiarity and their comfortable sizing.
|Smartphones feature an on-screen touch keyboard that's smaller than that of a standard computer. The smaller keyboard can make typing more difficult for users, especially those who have big fingers.
Most users today have both a smartphone and a computer in their home. They use a smartphone for phone calls, messaging, browsing the Internet, reading e-mail, and other small jobs and use a computer for more complicated projects or work. If you can't decide between a smartphone or a computer, consider getting a tablet or a hybrid computer.
