example of hardware

The diskette consists of a flexible, magnetic ti^J surface coated mylar disk inside a thin, non-removable, plastic sleeve. Thanks very much sir I learned something new. Viral Prajapati from Ahmedabad on August 28, 2017: Great way to explain here..All basic and important information are cover with video and images, It's a really good.. Its a great note. Zip drives could never become standardized and were replaced by rewritable CDs. Processing Devices. The data on a track is read sequentially as the disk spins underneath the head. I am a computer guru myself. This hardware device allows users to take videos or pictures, and transmit them over the Internet.

The function of main memory (also referred to as primary memory, main storage or internal storage) is to provide temporary storage for instructions and data during the execution of a program. Much more difficult to achieve than voice control, is true voice dictation used to dictate e.g. There are a number of different optical scanner technologies on the market. External hardware is equipment that connects to the outside of the main computer, such as a keyboard, mouse, printer, external hard drive or speakers.
Depending on how much light is reflected, a light-sensor determines the position and darkness (or color) of the markings on the paper. The Control Unit does the “housekeeping” i.e. Advanced models even allow for tactile feedback by means of small pressure pockets built into the glove. Two important types of RAM are: A small but essential element of any computer, ROM also consists of electronic memory microchips but, unlike RAM, it does not lose its contents when the power is switched off. Clara’s hardware will be competing against: Chain stores like True Value Hardware:New True Value hardware stores are specifically designed to appeal to female customers.

A standard CD-ROM can store 650 megabytes of data and the data can be transferred at many megabytes per second, though accessing non-sequential data takes much longer. Thank you! For example, it would be more efficient to scan a page of typed text into an information system rather than retyping it, but if this happens very seldom, and if typing staff are readily available, then the cost of the scanner might not be justified.
However, instead of indicating the time it takes to execute a single instruction, the processing speed is usually indicated by how many instructions (or computations) a CPU can execute in a second. These cards need to be pre-recorded following certain standards. The latest Pentium processor has a clock speed of about 4 GHz and contains well over 100 million transistors. Below is a list of the most common hardware you'd likely find inside a computer or connected to a computer today (desktop computer or laptop). The early versions of the diskette were fairly large (8″ or 5W) and had a flexible sleeve, hence the name floppy diskette. Very much like the CPU chips, their technology follows to the so-called law of Moore, which states that they double in capacity or power (for the same price) every 18 months. Since even a tiny container filled with the appropriate solutions contains many trillions of these molecules, one obtains in effect a hugely parallel computer.

Unlike normal RAM, flash memory is non-volatile i.e. Below is a list of internal hardware or hardware found inside a computer. Blu ray disc is an optical disc storage media format. Thanks a lot. Iomega came up with this medium-capacity storage media in 1994. These computers are typically used only for specialized applications such as weather forecasting or fluid modeling. It works closely with primary memory during its operations. They have a pen-based interface whereby a stylus (a pen without ink) is used on the small touch-sensitive screen of the handheld computer, mainly by means of ticking off pre-defined options, although the fancier models support data entry either by means of a stylized alphabet, which resembles a type of shorthand, or some other more sophisticated handwriting recognition interface. Register and cache: These are storage locations inside the processor that respond to the instructions of the control unit by moving relevant data around during processing. 6789 Quail Hill Pkwy, Suite 211 Irvine CA 92603. This is translated into electronic signals that direct the corresponding movement of a cursor on the computer monitor. These cookies will be stored in your browser only with your consent. Following you. Sound cards provide multimedia applications with the audio components. Screen size is usually measured in inches diagonally across from corner to corner and varies from as little as 12 or 14 inches for standard PCs, to as much as 40+ inches for large demonstration and video-conferencing screens.

Keyboard, mouse, headset, gamepad, printer. Large organizations such as banks, telcos and life insurance companies, require huge amounts of storage space, often in the order of many terabytes (one terabyte is one million megabytes or a trillion characters).

Where to buy computer hardware parts for my computer? However, all of the input devices described in this chapter have at least one thing in common: the ability to translate non-digital data types such as text, sound or graphics into digital (i.e. The layout of most keyboards is similar to that of the original typewriter on which it was modeled. Know how a flash drive works. Mouse There are quite a few different types of disk drives. Current disk storage costs as little Rl per gigabyte. By definition, the different parts of a computer are included in its hardware. Data cannot be recorded onto the disk. Examples include hard disk and solid state disk drives.

Some older hardware, such as joysticks and analog modems have been replaced by newer technology. Here is an overview of some of those pieces of hardware, which make it possible for a computer to be a part of a network.

These cookies do not store any personal information. Each position of the arm corresponds to a “track” on the disk, which can be visualized as one concentric circle of magnetic data. Even the DVD is not sufficient storage capacity and currently two optical technologies have been developed to increase storage capacity even further.

Although the popular IBM format only holds 1,44 megabytes, a number of manufacturers have developed diskette drives that can store from 100 to 250 megabytes per stiffy. This unit is not normally removable, though there are some models available where the unit as a whole can be swapped in and out of a specially designed drive bay. Production costs for a CD-ROM are less than Rl, even for relatively small production volumes. This was very helpful me to do my university assignment.Thank you very mush.

Alfred Amuno (author) from Kampala on December 09, 2017: Caleb Kiprotich seth on December 09, 2017: This a very good combination of Computer Basic Skills Which are useful ...Thanks for this plausible and fantastic ideas, Indeed this page is fully contained with all necessary guidelines for basic applications of this course . Although we will focus mainly on the personal computer (PC) and the peripheral devices that are commonly used with it, the same principles apply to the complete range of computers: 1. A computer mouse is a pointing device that detects two-dimensional motion.

Workstations, which provide high-level performance for individual users in computationally intensive fields such as engineering. Like it? Switching from electronic to light pulses offers a number of potential advantages: light (which consists of photons) can travel faster, on narrower paths and does not disperse heat. An AMD microprocessor is an example of a processing device. In fact many CPU chips now contain multiple “cores” each representing an individual CPU. CPUs use the control bus to communicate with other devices in the computer. This website uses cookies to improve your experience while you navigate through the website. During the fourth step of writeback, the CPU writes back results of the processed instructions into memory. Another exciting but currently still very theoretical development is the possible use of quantum properties as the basis for a new type of computer architecture. Optical disks, on the other hand, are rapidly becoming the storage medium of choice for the mass distribution of data/programs and the backup of data. As an illustration, compare a CD player (which can skip to any track almost instantly) with a music tape recorder (which has to wind the tape all the way through if one wants to listen to a song near the end). Output is the culmination of a cycle which starts with the input of raw data and processing. We also use third-party cookies that help us analyze and understand how you use this website. BD-ROM drive is used for reading data from a blu-ray disc and a BD writer can be used for both reading from and writing to a blu-ray disc. Hardware refers to the physical elements of a computer. Digital cameras allow you to make pictures of physical objects directly in a digital, i.e.

Alfred Amuno (author) from Kampala on October 10, 2017: Thanks Chad, hope it really is beneficial to the young fellows. Data is stored temporarily in processor cache and primary memory during the processing period.

How does one measure the speed of, say a Porsche 911? Apart from being very compact, most of these digital cameras can also interface directly with personal computers and are thus becoming a popular tool to capture pictures for e-mailing or loading on the world-wide Web. Their speed is therefore measured in megaflops (million of floating-point operations per second) or, in the case of very fast computers, teraflops (billions of flops). It is a computer program that is embedded in a hardware device. By combining the increased storage capacity with sophisticated data compression algorithms, a DVD disc can easily store 10 times as much as a CD, sufficient for a full-length high-quality digital motion picture with many simultaneous sound tracks.
