Computer Components: Internal and External Computer Components: Processor: A computer processer, otherwise known as the CPU (Central Processing Unit) is a part of the computer that receives input and decides that the output will be. Many modern CPUs are capable of processing trillions of calculations per second. The speed of a processor measured by how many operations a CPU can do in one second; this is done in MHz or GHz (Megahertz or Gigahertz). A processer with the speed of 1 MHz does 1,000,000 operations per second, and a 1GHz processer does 1,000,000,000 operations per second. This is known as the clock speed. Input: An input is when a computer receives data from external hardware such as a mouse, keyboard Output: An output is when computer …show more content…
This is a microprocessor that allows the computer to boot up. It also allows data manigment between the operating system. 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. GPU: GPU stands for Graphics Possessing Unit. It is used for 2D or 3D Graphics, outputting to display monitors,running graphic high intensity applications, etc.This is very mathematically intensive so it takes strain off the CPU. Hard Disc Drive: a HDD is like a person's long term memory. it is used to store any type of data from files to applications. The data on a HDD is non-volatile, which means the data will stay on the disc even if the computer is switched off. A SSD is another way to store data, but it is faster than a HDD because there are no moving parts. Motherboard: The motherboard is where many components such as the CPU, GPU, RAMetc.are connected. The motherboard does not hold any data itself. It also holds ports for input and output devices to be connected, such as a monitor, mouse, keyboard etc. Fans: A fans job is very important as it prevents important parts like the CPU from …show more content…
Case: A case is where all the computer components are mounted; the case protects the components from physical damage and also protects it from static electricity. Optical Drive: uses lasers to read or write data to/from optical discs like CDs or
The more space you have the more files you can save, such as pictures, music, movies, etc.
Your hard drives are what store all of your data, ranging from your operating system to your documents, music, and movies. If the RAM is your computer's short-term memory, your hard drive is the long-term memory. It stores the things you want to keep around for a while.
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.
Function- is to convert the outlet voltage to voltages that are used by components in the computer.
List and describe at least three types of storage that is typically included in all computer systems.
CPU : This is the central processing unit, better known as the processor. This is the heart of the PC where calculations are madeRAM: RAM stands for random access memory. This part in the PC grabs the file from the hard drive and stores on its non permanent memory so that you can have multiple windows open such as word and be able to access this data faster. The more RAM the faster and more apps you can open and the bigger the files the ram can hold. However, if you are using word and your pc crashes and you haven’t saved the file to the hard drive. The work that you have done will be lost due to that RAM does not hold on to files. GPU(Graphics card): The graphics
The processor receives the instructions from the operating system takes the information from the software and hardware then gives instructions to the processor, in simple terms the processor in one cycle fetches an instruction then decodes the instruction and finally executes the instruction when this is done it returns to the original step of fetching a new instruction.
The processor (otherwise known as CPU) is the very soul and performance core of the computer system; it is what allows the operating system and other software applications to-run. Every program demands dedication from the processor to decode commands that are then actionedinside the CPU to make them work.When a program is running, the CPU has to make every command work consistently one after the other. However, modern processors have the power to process commands side by side. This means that the quicker the commands are executed, the quicker the program responds to the user. Central Processing Units (CPUs) play an important role when it comes to maintaining
It is a program which is pre-installed on windows made PCs that the PC uses to start up. The function of BIOS is to check all the hardware connections and finds all
Computer- A computer the process-recieves in, thinks about, changes, stores, sends out, displays, and prints data in the form of bits.
The ALU performs mathematical, logical, and decision operations in a computer and is the final processing performed by the processor.
It executes instructions. The major companies that produce microprocessor for IBM and Macintosh computers are Motorola and Intel. Microprocessor requires a primary storage, a system clock and power supply to function as processor. Some families of microprocessor chips are used by quite a lot of types of PCs. The internal components of a standard microprocessor are Arithmetic logic Unit (ALU), Control Unit (CU), cache memory, internal buses and registers. The basic characteristics of a microprocessor are clock speed, instruction set and bandwidth. [Source: (Mcqsetscom,

DVD-ROM:Digital Versatile disk read only memory is used for storing large software applications. It permanently stores the data which is not erased or over written. It stores more than 4GB of data.
