The Hard Drive

Hard drives have and always will be an important consideration to think about when purchasing a new computer or used computer. Hard disk is most commonly used storage device in personal computers and laptop computers. Most application programs and operation systems require hard disk for installation and operation.


SpeedingComputer.com, the social network for computer enthusiasts, is giving away some cool prizes including a free 1 Terabyte hard drive. At Speeding Computer, “people come together to share, discuss and even show off the latest hardware, software and technology.” It is the hot new destination for all things computer related, and they have been creating quite a bit of buzz online.


many people sometimes have to bring their computers in for service. They would inevitably ask, “so do I have to just bring in the hard drive?” They, like many people referred to their computer as the hard drive. They meant the tower, that’s the tower part which holds all the computer stuff, as opposed to the peripherals of a computer like a mouse, keyboard, monitor, and printer. The hard drive actually resides inside your computer’s tower and it’s where all your files, folders and your operating system hang out.

The hard drive looks a bit like a record player (if you remember them). There’s a little arm and even a platter that goes around and around. The data for your computer is on that platter (or platters).
What you need to know about your hard drive is that it is one type of memory in your computer. There’s another type of memory in your computer called RAM or Random Access Memory and we’ll discuss that one next week. The hard drive is usually measured in hundreds of gigabytes
these days and the more gigabytes the more files and stuff you can put on your computer.


The hard drive will hold all your data until you delete it or until it fails. You should remember that hard drives can fail and that’s why keeping copies of your important data, like pictures and important documents to name just a couple of things, is vital. Back up those things to other media like a recordable DVD, a recordable CD-ROM, a flash drive or an external hard drive. And if you ever have to bring your computer in for repair, you can ask if it’s just the tower that you need to bring in because you know it’s not called the hard drive.

Processor

The computer processor is and will always be an important consideration when purchasing a computer. Processor is considered the brain of the computer. The CPU fetches instructions of program from main memory and executes them one by one. The speed of the CPU is measured in Mega Hertz or Giga Hertz and speed from 500 MHz to 3.4 GHz, it depends upon a user needs, that is why purchasing a processor is an important consideration when building or buying a computer. There are several considerations and additional information about what to ask and look for when purchasing a processor directly or already installed into a computer.Intel has introduced a new and flashier set of logos for their consumer-level processors and processor-cum-chipset combos, along with a star-rating system that may generate more trouble than guidance.
The new logos feature the familiar Intel logo above the marketing names of Core i7, Core 2, Centrino, Centrino 2, Atom, Celeron, and Pentium, with small print below listing qualifiers such as Extreme, Duo, Quad, and vPro.
The upper-right corner of the logos show a slice of a chip die in chip-like colors for the Core and Centrino families, but - oddly - in blue for the other
One blue-chip logo has no family name, just the time-honored "Intel inside" slogan. All the other logos include the term "inside" in the lower-right corner.

These rankings divide the Intel desktop and notebook offerings into five groups in ascending order of potency, with the one-star Celerons clinging to the bottom rung and the top-flight Core i7s and Core 2s standing proud on the five-star top rung.

While the star-rating system is a noble goal, it has one fatal flaw. Processors will inevitably slip down the ladder. And when they do, their rankings may change in Intel's marketing department, but not necessarily on shop shelves or salesfolks' minds.

When this first round of rankings expires at the end of September 2009, the confusion will begin. In early October, expect even those highly trained, whip-smart Best Buy sales associates to be flummoxed when trying to explaining why yesterday's laptop with a three-star Core 2 Duo mobile processor is as capable as a laptop that arrived after the Core 2 Duo mobile was re-starred at two.

Future Of Computer Technology

Computer Technology is expanding faster and faster and the future seems limitless for such an important sector, which has many wondering what the future holds for the industry. Currently there are technically advanced developments in the field of computer hardware, computer software and even the Internet that will change the way we work.
The way computer hardware is made and its function will soon be changing. Right now, there are a couple of new developments in this area of the future of computer technology

Next-Gen Interfaces

Many of these next-gen interfaces will not have the user control the computer through commands, but will have the computer adapt the dialogue to the user's needs based on its inferences from observing the user. Most current user interfaces are fairly similar and belong to one of two common types: Either the traditional alphanumeric full screen terminals with a keyboard and function keys, or the more modern WIMP workstations with windows, icons, menus, and a pointing device.
An alternative model is emerging in object-oriented operating systems where the basic object of interest is the user's document. Any given document can contain sub objects of many different types, and the system will take care of activating the appropriate code to display, print, edit, or email these data types as required. The main difference is that the user no longer needs to think in terms of running applications, since the data knows how to integrate the available functionality in the system

Nano Computers

According to a group of researchers calling themselves the Nanocomputer Dream Team, November 1st, 2011 is the day they'll unveil a revolutionary kind of computer, the most powerful ever seen. Their nanocomputer will be made out of atoms. Moving individual atoms around at will sounds like fantasy, but it's already been demonstrated in the lab. In 1989, scientists at IBM used an electron microscope to shuffle 35 xenon atoms into the shape of their company's logo. Since then a team at IBM's Zurich labs has achieved the incredible feat of creating a working abacus on the atomic scale. Nanocomputers, if they ever appear, will be extraordinary things. But if, like most computer systems, they have bugs, they could also be very nasty, as well. Of all the future technologies, Nanotechnology is the most exciting. By 2011, Nanocomputers can become a reality as a team claims to be working on it. A nanocomputer basically means atomic computer whose dimensions will be microscopic. Scientists and researchers have been working on suggestions for electronic, chemical, biochemical and quantum nanocomputers

Data Hiding

A major concern for creators of digital content, whether it's Web content, music, or movies on digital disc, is to protect their work from unauthorised copying and distribution. DataHiding is a technology that allows owners of content to embed data invisibly or inaudibly into other digital media, such as video, audio data, or still images. When the data is embedded, it is not written as part of the data header, but rather embedded directly into the digital media itself. This process changes the original digital data, but the change is so slight that it cannot be visually detected, and has no impact on the performance of the original data.
The beauty of DataHiding is that it gives content creators a powerful means of marking their digital creations without affecting the end user's appreciation of it. The embedded information does not change the size of the original data, and it survives normal image processes such as compression and format transformation

Protonic Memory

One of the biggest horrors of the computer age is to be working on a document not yet saved to the hard drive and lose everything because of a power outage or a system crash that forces the operator to shut down the computer. Attempts to create circuits that store the information when the power is interrupted have used high voltages, which quickly wear down computer electronic components, and have been expensive. Some scientists have applied for a patent on a prototype memory retention device that is inexpensive, low-powered, and simple to fabricate that may be the future of protecting vital data when suddenly lost without being save. To transmit data, the device uses embedded protons, which remain where they are when the power turns off, thus preserving the information. In devices such as DRAM's (dynamic random access memory), typically based on electron flow, the information is lost when the power is turned off.
