Important Computer Hardware Components And Parts

Computer hardware consists of the different components of a computer including the CPU or the Central Processing Unit, mouse, keyboard, monitor, hard disk, RAM or memory, drives such as the DVD, CD, optical, tape and so forth. All these components are essential for the proper functioning of a personal computer.

Understanding Computer Hardware in Detail

The whole computer is available with the above mentioned components but it is also possible to purchase these components individually from many of the online and offline stores. Some of the most important components include the following:

  • Central Processing Unit or the CPU: the CPU refers to the processor of the computer. Although there are a wide number of companies that manufacture CPUs or processors for personal computers, the Pentium chip manufactured by Intel is widely and commonly used by most of the manufacturers.
  • Keyboard: most important computer hardware includes the keyboard which is essential to enter commands and words. Every key in the keyboard is a representation of an alphabet, number, sign, function and so forth. There are keys which represent actions like Delete, Enter, Alt, Ctrl, Page Up, Page Down, Home, End and many more. Each different key has a specific

New computer program predicts cochlear implant success in hearing-impaired children

A new computer program that analyzes functional brain MRIs of hearing impaired children can predict whether they will develop effective language skills within two years of cochlear implant surgery, according to a study in the journal Brain and Behavior.

In the journal’s Oct. 12 online edition, researchers at Cincinnati Children’s Hospital Medical Center say their computer program determines how specific regions of the brain respond to auditory stimulus tests that hearing-impaired infants and toddlers receive before surgical implantation.

With additional research and development, the authors suggest their computer model could become a practical tool that allows clinicians to more effectively screen patients with sensori-neural hearing loss before surgery. This could reduce the number of children who undergo the invasive and costly procedure, only to be disappointed when implants do not deliver hoped-for results.

“This study identifies two features from our computer analysis that are potential biomarkers for predicting cochlear implant outcomes,” says Long (Jason) Lu, PhD, a researcher in the Division of Biomedical Informatics at Cincinnati Children’s. “We have developed one of the first successful methods for translating research data from functional magnetic resonance imaging (fMRI) of hearing-impaired children into something with

Understand Your Computer Hardware

Computers have become an inseparable part of our culture and we cannot think of a life without computers. They are everywhere; from the calculator in your pocket to the space-ship that landed on a moon, from mobile phones to the satellites, from the desktop PCs to the supercomputers, from sports to industries, and from our kitchen to the white house; they perform countless functions. To understand your computer hardware, you do not need to open the cabinet of your PC, you can start with the basic of computer hardware.

What is Computer Hardware

Computer hardware is a set of devices that are interlinked to get the tasks done by the computer. For computers to run, both hardware and software are required. Software are the automated programs that help us to communicate with the machine and get the results.

Motherboard

Motherboard is a word used in reference with a board that holds many computer hardware partstogether.

CPU: Central Processing Unit is the brain of your computer system. It shows which generation your computer belongs to.

RAM: Random Access Memory is an internal memory that all the input and output functions make use of, while dealing with the CPU.

Motherboard also holds chip

Computers Parts of Computer Hardware

Parts of computer hardware have to be handled carefully, so that they assure maximum effectiveness in the long run. Moreover, a personal computer has become a basic commodity of daily use, wherein, most of the day-to-day human activities depend on them. Therefore, it is essential to possess at-least some basic knowledge about various computer peripherals.

When you decide to purchase a computer, usually initial assistance is provided by the customer care centre of your dealer. An engineer or a maintenance expert gives a visit to your house to check whether the hardware has been installed properly or not. During this time, you can ask about various doubts and get clear explanations about the basic functioning of your PC. Apart from this, you can also refer to computer hardware related books and refer to magazines.

Generally, plenty of information is available on internet on various computer hardware related websites. Most of the manufacturers and computer hardware dealers have their official websites that give descriptions about the usage and assembling of computer peripherals. You can simply surf through a couple of websites to get the basics of computer peripherals, understand their functions and learn about their maintenance techniques.

A personal computer normally consists of basic

A Look at Metadata

A Young girl sticks her toe in a baby’s mouth snaps a photo and sends the picture out on snapchat. Within hours, investigators are at the residence and a case is opened up for abuse in Gaffney, South Carolina. The victim (a baby) is identified and the perpetrator (a fifteen year old girl) is being referred to Juvenile Justice for adjudication. The question is, how did they find and locate this place so quickly? The answer is, Metadata. A rogue NSA contractor has convinced the American public that the government is using metadata to track each one of them. What is Metadata?

Metadata will cause you a Law Enforcement and Criminal Prosecution problem if you are involved in murder, child pornography, illicit drug activity, cyberstalking, etc. If you are an “Enemy of the Government” (involved in Terrorism, Assassination of Officials, Government Overthrow, illegal Computer Cracking, etc.), metadata can cause you problems. The NSA (an Agency within the Department of Defense) is not concerned (or interested) in your affairs, Mona’s sexting or Joe’s robust porn collection and his obsessive self gratification.

What is Metadata

Metadata is data that describes a file or directory (data about data). A computer system is typically filled with files.

Imaging a Linux System

Acquiring a Linux Image

The Administrator is in need of a bit for bit image pending an investigation. When we acquire an image, we are actually performing either an entire hard drive for all of the information on the drive or a single partition. Under Linux we have the advantage of having a built in tool (which is one of my favorites) that will allow us to do an image capture. That built in tool is actually called ‘dd’ (disk dump) (which most Administrators refer to as dupe disk).

For example, the syntax to capture information from a USB drive named Clyde will be:

#sudo dd if=/dev/sda1 of=Clyde.dd

The command ‘dd’ actually grabs a bit for bit image of this USB drive. It can grab a partition or an entire hard disk. For every bit that is on the drive, we will be writing out that image to this file which is called Clyde.dd.

The output of ‘dd’ is what we would consider a raw format because we haven’t done anything to it at this time. It is not in any other form other than the way it was exactly stored on the drive. This makes it a tool investigators and administrators use

Less computing time for sand

Computer graphics today can produce amazingly photorealistic images. Many motives, however, require very long computation times. Researchers of KIT, Disney Research, Zurich, and Cornell University have now developed a process, by means of which granular objects made of e.g. sand, snow or sugar can be computed more quickly. It was presented recently at the ACM SIGGRAPH 2015 International Conference for Computer Graphics in Los Angeles.

“Objects of granular media, such as a sandcastle, consist of millions or billions of grains. The computation time needed to produce photorealistic images amounts to hundreds to thousands of processor hours,” Professor Carsten Dachsbacher of the Institute for Visualization and Data Analysis of KIT explains. Materials, such as sand, salt or sugar, consist of randomly oriented grains that are visible at a closer look only. Image synthesis, the so-called rendering, is very difficult, as the paths of millions of light rays through the grains have to be simulated. “In addition, complex scattering properties of the individual grains and arrangement of the grains in a system can prevent classical acceleration techniques from being used. This makes it difficult to find efficient algorithms,” doctoral student Johannes Meng adds. “In case of transparent grains and long

Faster optimization of computer algorithms

Optimization problems are everywhere in engineering: Balancing design tradeoffs is an optimization problem, as are scheduling and logistical planning. The theory — and sometimes the implementation — of control systems relies heavily on optimization, and so does machine learning, which has been the basis of most recent advances in artificial intelligence.

This week, at the IEEE Symposium on Foundations of Computer Science, a trio of present and past MIT graduate students won a best-student-paper award for a new “cutting-plane” algorithm, a general-purpose algorithm for solving optimization problems. The algorithm improves on the running time of its most efficient predecessor, and the researchers offer some reason to think that they may have reached the theoretical limit.

But they also present a new method for applying their general algorithm to specific problems, which yields huge efficiency gains — several orders of magnitude.

“What we are trying to do is revive people’s interest in the general problem the algorithm solves,” says Yin-Tat Lee, an MIT graduate student in mathematics and one of the paper’s co-authors. “Previously, people needed to devise different algorithms for each problem, and then they needed to optimize them for a long time. Now we are saying, if for
