TopicComputerSmartphone/TabletPowerIf you want high performance, the CPU uses a lot of electricity. The TDP 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.CostPrices 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 along with a service plan from providers such as Verizon or AT&T. Refurbished smartphones can be purchased on an e-commerce site such as 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.Screen sizeDesktop 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 much 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.PortabilityWhile 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.StorageConsumer 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 that is 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. In some cases, 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.SoftwareDesktop 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.Internet ConnectivityDesktop computers generally come with Ethernet capability, either on the motherboard or a discrete NIC. Most desktop computers require a peripheral device, such as a USB 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 connectMany of the tasks handled by a computer may also be done on a smartphone or tablet.

Explanation:
Memory

The term ‘memory’ refers to the component within your computer that allows for short-term data access. You may recognise this component as DRAM, or dynamic random-access memory. Your computer performs many operations by accessing data stored in its short-term memory. Some examples of such operations include editing a document, loading applications and browsing the internet. The speed and performance of your system depends on the amount of memory that is installed on your computer.
If you have a desk and a filing cabinet, the desk represents the memory of your computer. Items you need to use immediately are kept on your desk for easy access. However, not much can be stored on a desk due to its size limitations.
Storage

Whereas memory refers to the location of short-term data, storage is the component within your computer that allows you to store and access data on a long-term basis. Usually, storage comes in the form of a solid-state drive or a hard drive. Storage houses your applications, operating system and files for an indefinite period. Computers need to write information and read it from the storage system, so the speed of the storage determines how fast your system can boot up, load and access what you’ve saved.
While the desk represents the computer's memory, the filing cabinet represents the storage of your computer. It holds items that need to be saved and stored but are not necessarily needed for immediate access. The size of the filing cabinet means that it can hold a large number of things.
An important distinction between memory and storage is that memory clears when the computer is turned off. On the other hand, storage remains intact no matter how many times you shut off your computer. Therefore, in the desk and filing cabinet analogy, any files that are left on your desk when you leave the office will be thrown away. Everything in your filing cabinet will remain.
