The document summarizes key hardware components of a computer: 1. A monitor displays pictures and is used to view programs, differing from a television in lacking a tuner for changing channels. Some monitors can function as televisions and vice versa. 2. Computer memory, often called storage, retains digital data for computing and provides core functioning, working with the processor to implement the basic computer model. 3. A central processing unit (CPU) or processor can execute computer programs, with its fundamental operation remaining the same despite dramatic changes to its form and design over time. 4. A motherboard is the central printed circuit board that serves as the base for complex electronic systems like personal computers.

2. Monitor A computermonitor is an electronic device that shows pictures. A monitor is usually used to see programs on a computer. The main difference between a monitor and a television is that a monitor does not have a television tuner to change channels. A monitor may be used to watch television if it is connected to a device that has a television tuner. Some models of monitor can be used as a television, and some televisions are used with computers. A monitor has a better display resolution than a television to make it easier to see smaller letters and graphics on.

3. MemoryComputer data storage, often called storage or memory, refers to computer components, devices, and recording media that retain digital data used for computing for some interval of time. Computer data storage provides one of the core functions of the modern computer, that of information retention. It is one of the fundamental components of all modern computers, and coupled with a central processing unit (CPU, a processor), implements the basic computer model used since the 1940s.

4. ProcessorA central processing unit (CPU) or processor is an electronic circuit that can execute computer programs. This term has been in use in the computer industry at least since the early 1960s (Weik 1961). The form, design and implementation of CPUs have changed dramatically since the earliest examples, but their fundamental operation has remained much the same.

5. Mother BoardA motherboard is the central printed circuit board (PCB) in some complex electronic systems, such as modern personal computers. The motherboard is sometimes alternatively known as the mainboard, system board, or, on Apple computers, the logic board.[1] It is also sometimes casually shortened to mobo.[2]
