Computer Hardware - Learn computer fundamental concepts in simple and easy steps starting from Overview, Applications, Generations, Types, Components.
This is the hardware. But what you don't see is the software. Software is all of the computer programs, or code, running on this machine. Software can be anything from apps and games to webpages and data science software that me and my teams use at Amazon to understand how customers behave.
But how do the hardware and the software interact with one another?
Lets start at looking at a computer's central processing unit, or CPU. A CPU needs to do different things, so inside it has smaller, simpler parts that handle specific tasks.
It has circuits to do simple math and logic, it has other circuits to send and receive information to and from different parts of the computer. The real magic of the CPU is how it knows which circuits to use and when to use them. For example, and add command tells the CPU to use its adder circuit to calculate a new number. And then the store command tells the CPU to use a different circuit to save that result into memory.
Some of them are described below.
The term dynamic indicates that the memory must be constantly refreshed or it loses its contents. This type of memory is more economical. The term static is derived from the fact that it does not need to be refreshed like DRAM.
This type of memory is non-volatile. The information is stored permanently in such memories during manufacture.
A ROM, stores such instructions that are required to start a computer. This operation is referred to as bootstrap.
The different types of ROM are given below. The MROM cannot be programmed by the user. EPROM is erased by exposing it to ultra-violet light for a duration of up to 40 minutes. It can be erased and reprogrammed about ten thousand times. Both erasing and programming take about 4 to 10 milliseconds. Secondary Storage External Storage Devices Floppy diskettes, hard disk, tapes and optical disks come under the category of external storage devices or ancillary storage devices.
These devices are very sensitive to environmental conditions humidity and temperature as well as to external magnetic fields and need to be stored carefully. Information on a floppy disk is recorded in the magnetized states of particles of iron oxides evenly placed upon concentric circles known as tracks. It contains a stack of metal platters, each coated with iron oxide, that spin on a spindle and the entire unit is encased in a sealed chamber.
C Magnetic Tape This is plastic tape, usually made of Mylar that is coated with iron oxide, thereby enabling the introduction writing ; retention memory and reading of magnetically recorded information. The best use of tape storage is for data that you do not use very often. If a peripheral device is disconnected, the computer will still be able to work; only functions performed by this peripheral device will not be available.
Here are the most used types of peripheral devices: A Keyboard The most common and very popular input device which helps in inputting data to the computer.
It consists of keys that are capable of inputting alphabets, numbers and special characters. You can also navigate using the keyboard and perform shortcut functions. B Mouse Mouse is the most popular pointing device and cursor-control device having a small palm size box with a round ball at its base which senses the movement of mouse and sends corresponding signals to CPU when the mouse buttons are pressed. They then move on to study various models for presenting data, such as cartograms and hyperbolic trees, before choosing one to create their own representation.
At the culmination of this course, students will have broadened their understanding of the computer tools available in displaying various data. The Incredible Shrinking Chip features a combination of lectures and videos covering how microchips work. The evolution, application, and inner workings of the microchip are discussed, along with the future potential of this technology.
Eli the Computer Guy Computer Hardware Repair is a video lecture offering instructions on how to repair the most basic computer hardware issues. The course also offers tips on the benefits of repairing computers versus replacing them.
The video lasts slightly less than an hour. San Francisco City College Intro to Computer Hardware is a free lecture offering students information on the basics of computers and computer hardware. Students learn how computers are connected together as well as their many functions. Computer languages, binary numbers, and bus connections are discussed.
TV, an online network offering more than 30 hours of weekly content on technology.
This Week in Hardware has over lecture videos to choose from. Each video covers a different topic, although they're all related to computer hardware. Students can learn about motherboards, CPUs central processing units , RAM random-access memory , drives, monitors, and routers.
