A computer is a machine capable of taking input and processes it to create new information (output).
The calculation of machines is old in the history of technology. The initial examples are Astrolabe and abacus. Today, a computer is a programmable machine. The computer has two main characteristics: it responds to a specific instruction set in a well-defined manner and it can execute a preceding list (a program) of instructions. There are four main processing steps in the computer: input, storage, output, and processing.
The main point of the computer :
- The word Computer is Obtained from the Latin Word " Compute" which means "to calculate or "to "count".
- Just Like Other Machines Make Work Easier.
- Majority of People have referred PC (Personal Computer) as the Real Computer.
- A computer can also be described as an electronic Machine that saves, transmits and process data into information.
- For Example: In calculator add the two numbers 5+5=10.in which (5+5) as input and the (10) is Output is Represent on Screen.
- A computer is a Machine that performs four basic operations: input processing, output processing, Storage. these four operations are called the information-cycle.
Most desktops and laptops are sold with pre-installed software and operating systems such as Windows 7, or if it is an Apple Computer, then Mac OS.
Both computer units come with port connections (separate between each make and model) and embedded CD / DVD component, however, some of these step-by-step steps are the latest laptops.
Peripheral external hard drives, printers, cameras, and phones etc. can be connected to devices.
For desktops and laptops, there are important specifications to consider before purchase.
Cpu
Memory (RAM)
Hard Drive Capacity
graphics card
These glasses determine the limits of the computer so that the video output is the primary function and the computer has an end-end graphics card, the computer (laptop or desktop) is a better fit.

The Main difference between desktops and laptops
The biggest and most noticeable difference is that the desktop requires basic external devices to be fully functional, while laptops have all the necessary devices, which make it the most portable.
Mobility
The desktop office or home is in place and requires a computer terminal to connect to the external monitor, keyboard, and mouse; While laptops have built-in components and thus are easily transported as a full device which can be used in most environments.
Power
The laptop can run AC power, battery, or main power, while the desktop can only run the main powers. It is not manufactured for any battery usage.
Over time, the laptop battery has improved and depending on how much processing power is being used and the opening of WiFi or Bluetooth connection, the consumption of batteries increases depending on how long it can run for several hours.
Speed
While desktops and laptops are becoming more equal in terms of speed and performance specifications, the desktop still remains as a more powerful alternative to activities like gaming and video production.
Buying the same glasses of gaming laptops on the gaming desktop will be at a much higher cost than the gaming desktop.
If a computer is required to view original office processing, internet usage, and photos, then a standard laptop will be perfectly suitable.
Specifications
Generally, laptops are known for fewer spectacles than desktop, because there is a compromise on size and portability, versus performance and speed.
Screen size:
Desktop monitors can be up to 34 inches wide by 15 inches screen. Laptops have built-in screens that have different sizes.
The bigger the screen, the bigger the laptop, the larger it will be, however, if a small laptop is bought for easy mobility, then it can be connected to a larger external monitor if possible.
If connecting an external monitor on an external computer that permanently resides in one place, the size of the monitor will not be a restrictive factor as it is set up once and is not necessarily transferred, hence weight is an issue Not there.
Storage, Memory, and Data:
To store large amounts of data, desktop computers will be a better option and if necessary, additional memory can be added to improve performance, or hard drives can be replaced. Laptops cannot be expanded as easily as the desktop.
Backup is recommended for all data, even if it stays on a desktop or laptop, even if using a laptop causes the risk of data moving with mobility due to theft, loss of computer, physical damage (drop Leaving) computers, etc.
