Basic Computer Hardware and Software

The Operating System manages the flow of data and tells the processor what component needs to be doing. It does this my relaying one piece of information at a time but done so fast it seems it is doing it all at the same time. It does this by giving the information to the processer in computer language, so it can understand.

RAM: RAM stands for Random Access Memory. It is a bit like a person's short-term memory. RAM is volatile so data only exists only when the computer is turned on, and is used by the operating system and other applications.

BIOS (Basic Input Output System): BIOS set up the computer and boot the operating system it also handles the system setup process including driver loading.

What do CPU’s do? The CPU is the Central Processing Unit; its aim is to be there the act as the brain of the computer. Other common name for the CPU is the processor. It is in control of the power the computer is receiving and using and the calculations that enable to the computer to be used. CPUs come in differing form factors and each has a particular way in which it will fit on to the motherboard. The most common manufactures of this part that people will know are Intel and AMD. The CPU is in charge of allowing programmes to be used. The CPU sorts the commands of a program into an order which enables it to be used.

A CPU, is what is regularly alluded to as a processor. A processor contains numerous discrete parts inside it, for example, one or more memory reserves for directions and information, guideline decoders, and different sorts of execution units for performing number juggling or legitimate operations.

Motherboard is centralized computer of the PC that all framework inside the electronic in light of the fact that a few sections are not quite the same as each other like RAM, CPU and framework unit

CPU stands for Central Processing Unit and it’s the brain of the computer. CPU executes instructions that enable the operating system and application software to run on a system. Inside the CPU we can find three main components which are the ALU, Control Unit and memory unit. ALU stands for Arithmetic and Logic Unit and performs calculations like addition, multiplication, division and subtraction. It also compares results using “greater than”, “less than” or “equal to”. Control Unit controls the operation of the memory unit, processor and input/output units. Memory unit is where all data that the CPU may need to process is stored. The data is stored in the memory in binary form.

Answer: hardware and software is the core of the computer without it computer cannot perform its task. The PC contains various electronic components that we are able to see when we open it. By only pc by itself cannot perform their task on their own. Our PC needs something to get instructed to set it on where we need software to perform it. There are six different component of hardware to function the computer .The first one is central processing unit(CPU )it is the brain of the

The CPU is housed in the motherboard is considered the heart of the computer, it controls everything. CPU stands for central processing unit; it is one of the main components of a computer. The CPU or more commonly known as the processor is electronic circuitry which follows the instructions of the hardware and software on the computer, it effectively is a very efficient calculator carrying out arithmetic, logical, control and input/output operations.

Processor (or Central Processor Unit, CPU) is a computer brain and has the function to fetch, decode and execute and is located in the motherboard. By placing a CPU in a wrong place it brakes.

There are two types of control unit which are hardwired and micro program where hardwired are for fixed architecture and are typically RISC and cost more than micro program because of the time required to design the circuits , but they are faster. Micro program control units are slower than hardwired but are easier and cheaper to implement as the instructions are stored in special control memory. The control unit controls all data going in, out and inside the CPU. The control unit decodes the data from ram and turns it into an instruction depending on what instruction set the control unit is programed or hardwired to have. Then if the instruction involves any logic or mathamatical caluculations it gets sent to the alu

A computer is an electronic device that stores, retrieves, and processes data, and can be programmed with instructions. A computer is composed of hardware and software, and can exist in a variety of sizes and configurations. Hardware is the physical equipment of a computer system, including the central processing unit (CPU), data-storage devices, terminals, printer, etc. Software is a program or set of instructions or rules that control the operation of a computer.

Controls - The most important input controls are the keyboard and the mouse. The mouse is moved by hand over a flat surface to control the position of a cursor on the screen. The shape of the cursor varies depending on the task; the most common shape is an arrow the. Job of the mouse is to perform an action on the screen that makes the computer do something. To do this, put the tip of the arrow over something on the screen, and press and release the left mouse button once (known as ‘clicking’) or twice, rapidly (known as ‘double-clicking’). By pressing and holding down the left mouse button and then moving (dragging) the mouse, you can also use the mouse to make a selection, move a window or an object. If something is moved in this way, it is known as ‘drag-and-drop’.

a controller may be an expansion card, an external device or a chip which manages the operation or functions of a specific task or command. They work as a link or a channel which integrates two parts of a computer.(A good example would be Graphics controller which manages access to Graphics card or Video Card )
