What is a computer?
A computer is an electronic device for storing and processing data and performing calcification, typically in binary form according to instructions given to it as detailed in a running program. It is designed to carry out multiple tasks. Early computers were the size of a large room and consumed a huge amount of electricity.
With technological advances, modern computers work on the integrated circuit and can be small enough to fit into a mobile device. Personal computers are icons of the present Information Age.https//www.wikipedia.com/computer Embedded computer found in many devices, from MP3 players to fighter aircraft and toys to industrial robots.
Computer hardware.
Computer hardware consists of physical components included the mechanical, magnetic, electronic, and electrical components that make up a computer system. It also includes the physical parts of a computer system such as the monitor, keyboard, motherboard, random, access, memory, (RAM) cards, data storage device, hard disk drive, mouse, central processing unit (CPU), graphic card sounds Card and the power supply cables. These are typically installed into a computer case or attached to it by cables or through a port.
The function of the CPU.
The CPU is often called the brain of the computer and controls the function of a computer. It is a microprocessor chip that does most of the data processing. It carries out each instruction of the program in sequence to perform the basic arithmetical logical and input/output operation of the system.
A computer can have more than one CPU; this is called a multiprocessor. Some Integrated circuits (ICs) can contain multiple CPUs on a single chip; those ICs are called multi-core processors.
The main components of the CPU.
The main components of the CPU are the arithmetic logic unit (ALU), logical operations, and the control unit (CU), which extract instructions from memory and decodes and executes them, calling on the ALU when necessary.
What is the monitor?
- A monitor is a device that displays information or computers output in visual form using text and graphics, and the portion that displays the same is called the screen. These monitors are of two types:
- Cathode ray tube (CRT) monitor
- Modern liquid crystal display (LCD) monitor.
Gradually the LCD monitor is being replaced by a light-emitting diode ( LED) monitor that provides higher contrast and better viewing angles.
How does a keyboard work?
A keyboard is an input device with an arrangement of buttons or keys, which uses switches and circuits to translate a person's keystrokes into a signal the computer can understand. https://paidforarticl.com/computerThe inside of the keyboard consists of a processor and circuit. The keyboard processor contains a grid of circuits called a key matrix.
Most keyboards have between 80 and 110 keys, detailing typing keys, numeric keypad, function keys, and control keys. Each circuit is broken at a point below each key. When a key is pressed, it presses a switch, completing the circuit and allowing a tiny amount of current to through, which causes a vibration called bounce, signaling the processor to read it.s,
What is a computer mouse?
A computer mouse is a hand-operated electronic device that controls the coordinates of a cursor on your computer screen as you move it around on a pad. A mouse's most common standard features are two buttons and a scroll wheel, which can act as a third button. A computer mouse functions by detecting two - dimensional motion relative to its supporting surface. The mouse motion typically translates into the motion of a pointer on display, which allows for fine control of a graphical user interface.
What is a webcam?
A webcam is a digital video camera that can be attached to a computer and can download images in real-time to a computer for transmission over the Internet or other networks. This camera also facilitates long-distance communication like video conferencing.
What is Ram?
Ram or random access memory is a type of computer memory that can be accessed randomly, which means that any byte of memory can be accessed without touching the preceding byte. Physically, it is a series of chips in a computer. When a computer is turned on, it loads data into RAM. Individual blocks of data can be stored or retrieved in any order rather than sequentially.
The RAM temporarily Store information that the CPU use while the computer is on. The information stored in the RAM is erased when the computer is turned off.
