3 Home Wireless Network Points

January 27th, 2010

Now a days having a wireless network available to you is more normal than abnormal. Many reasons have led to this change, one being cost. It is very cost effective so set up a wireless network as opposed to a wired network.

Because of the rise in wireless network popularity, more and more computer manufacturers are equipping their systems with the right wireless networking hardware. I am going to discuss 3 big points, wireless networking in laptops, desktops, and also the software on these machines

So we start off with a very important question – Is your laptop or home computer wireless enabled? This is how you can check if your computer has wireless capabilities or not.

Laptops

Many newer laptops have wireless networking capabilities already built in to them. If you laptop came with the hardware built inside of it, then all you need to do is make sure it is enabled and the button on the front (usually) of the laptop is lit up. If a wireless PCMI card is needed in the laptop computer, then make sure it is compatible with your brand of computer first. When you install it, make sure you have the driver disk associated with the hardware, and that it’s driver matches what version of Windows you have.

Desktop Computers

If you need to check to see if your desktop computer has a wireless connection, turn off the computer and turn it around and look for a rod sticking out near the bottom of the tower. This would be the wireless antenna just like an antenna would be on a radio. If you see nothing like this then your desktop probably does not have a wireless card installed in the PCI slot. So buy one that matches the version of Windows that you have on the desktop.

Windows to check the Wireless Capacity

Once everything is installed on your laptop or desktop you want to use windows to check the wireless capacity to make sure the settings are correct. Open up the Device Manager in Windows. Look for the network adapters + sign and click it. Look for something under there that should have the term “wireless” attached to it. If you see that there then you know everything has been configured correctly and all you need to do is connect to the available wireless network.

Evolution and types of Personal Computer

January 19th, 2010

In general term Home computer means computer for personal use. It is also called as PC. It is any general-purpose computer whose size, capabilities, and original sales price make it useful for individuals, and which is intended to be operated directly by an end user, with no dominant computer operator. A PC may be used at home, or may be found in an office. Personal comptuers can be connected to a local area network (LAN) either by a cable or wirelessly. While early PC owners usually had to write their own programs to do anything useful with the machines, today’s users have access to a wide range of commercial and non-commercial software which is provided in ready-to-run form. Since the 1980s, Microsoft and Intel have been dominating much of the personal computer market.

Personal Computer was a class of personal computer entering the market in 1977 and becoming increasingly common during the 1980s. They were marketed to consumers as accessible personal computers, more capable than video game consoles. These computers typically cost much less than business, scientific or engineering-oriented desktop personal computers of the time, and were generally less powerful in terms of memory and expandability. However, a home computer often had better graphics and sound than contemporary business personal computers. Usually they were purchased for education, game play, and personal productivity use such as word processing.

Workstation – SuperFast PC of new world

Types of Personal Computer – PC

A personal computer may be a desktop computer, a laptop computer, tablet computer or a palmtop.

* Workstation

A workstation is a high-end personal computer designed for technical or scientific applications. Intended primarily to be used by one person at a time, they are commonly connected to a local area network and run multi-user operating systems.

* Nettop

A subtype of desktops, called nettops, was introduced by Intel in February 2008 to describe low-cost, lean-function, desktop computers. These feature the new Intel Atom processor which specially enables them to consume less power and to be built into small enclosures.

* Desktop computer

Prior to the wide spread of PCs a computer that could fit on a desk was considered remarkably small. Today the phrase usually indicates a particular style of computer case. Desktop computers come in a variety of styles ranging from large vertical tower cases to small form factor models that can be tucked behind an LCD monitor. Most modern desktop computers have separate screens and keyboards.

* Netbook

Netbooks are small portable computers in a “clamshell” design, that are designed specifically for wireless communication and access to the Internet. They are generally much lighter and cheaper than subnotebooks, and have a smaller display, between 7″ and 9″.

* Laptop

A laptop computer or simply laptop, also called a notebook computer or sometimes a notebook, is a small personal computer designed for mobility. Usually all of the interface hardware needed to operate the laptop, such as parallel and serial ports, graphics card, sound channel, etc., are built in to a single unit. Laptops contain high capacity batteries that can power the device for extensive periods of time, enhancing portability.

* Tablet PC

A tablet PC is a notebook or slate-shaped mobile computer. Its touchscreen or graphics tablet/screen hybrid technology allows the user to operate the computer with a stylus or digital pen, or a fingertip, instead of a keyboard or mouse.

* Ultra-Mobile PC

The ultra-mobile PC (UMPC) is a specification for a small form factor. It was developed as a joint development exercise by Microsoft, Intel, and Samsung, among others.

* Home theater PC

A home theater PC (HTPC) is a convergence device that combines the functions of a personal computer and a digital video recorder. It is connected to a television or a television-sized computer display and is often used as a digital photo, music, video player, TV receiver and digital video recorder.

* Pocket PC

A pocket PC is a hardware specification for a handheld-sized computer that runs the Microsoft Windows Mobile operating system. It has many of the capabilities of modern desktop PCs.

PC- Home Computer Trends, Types and Technology

Evolution of Personal Computer – PC

The introduction of the microprocessor, a single chip with all the circuitry that formerly occupied large cabinets, led to the proliferation of personal computers after about 1975. In what was later to be called The Mother of All Demos, SRI researcher Douglas Englebart in 1968 gave a preview of what would become the staples of daily working life in the 21st century – e-mail, hypertext, word processing, video conferencing, and the mouse.

The Aged 50 Plus – Home Computer Optimization Situation

January 10th, 2010

The 50 plus crowd within the United States didn’t grow up using computers at school or within the work environment because in our early years the desktop computer and laptops didn’t in all actuality exist within the consumer marketplace. We have cell phones now that are smaller than the size of a cinder block and computers no longer require more square footage than a five room home. Yes, time has progressed and I’m proud to say the fifty plus crowd my children seem to think are 10 days older than dirt; managed to adapt to the modern day technical advances as well.

Computer use by our aging population revealed in 2004 that 46% of those aged between 59 to 68 now use and enjoy Internet access at home. Just over 76% of those within the ages of 50 and 58 use computers as a direct result of computers being a common place necessity and requirement to function or perform our jobs within the modern day work environment. However, it must be noted using a work computer and having to keep it optimized and safeguarded is usually the task of the resident wiz kid or a dedicated technical type (IT) staff. So what happens when the home PC slows, crashes or is somehow compromised?

As I see there are a number of emergence repair tactics that can be implemented. First and foremost is the panic call to our children to come over and troubleshoot the situation. After all, they have been using computers since first grade and that pretty much makes them an expert right? Once you discover their ability to social network and post videos on Utube doesn’t speed up the computer the second option is; to research and find registry repair, spyware, adware and about 100 other software solutions that have incremental probabilities of resolution. Last but not least the computer can be drug into a service facility or a technician home visit can be scheduled that will ultimately cost as much as a 2d mortgage home loan. Well, none of that has any source of good old fashioned stubbornness and common sense. As I also see it ‘ there is always a solution in the face of any and all problems.

I remember that conversation at the plant where something sounding a lot like a termination threat motivated me to actually start touching a computer keyboard way back when. I still remember a series of training classes that I attended that were moderated by a technician that today wouldn’t be allowed to have friends in his car let alone use a cell phone while operating a motor vehicle. Seems to me he still had spit behind his ears. But, putting all that behind, he did a really great job of teaching all of us how to get around those old computer operating systems proficiently. We were ready to tackle Donkey Kong, Pong and any Atari game in existence buried in the home closet. That being a monumental achievement I like many others actually bought a home computer. I used it a lot and as all things being put into use, the computer slowed to a crawl.

I’m lucky because somewhere in the process of aging I found time to attend a technical trade institute where despite the fact my classmates thought I was a professor; I along side of them learned to build a computer from the ground up. Some of the residual training included troubleshooting the system and a resulting ability to keep it and my personal and financial information safeguarded from intruders that come in the form of hackers, worms, Trojans, viruses, adware, etc., etc. I learned to do a mass of little things to keep it (the computer) optimized as well and these series of events; are things we all need to learn to do.

Most people are clueless when it comes to debugging, defragging, defusing this that or whatever it takes to keep the home computer operating efficiently. But, the simple fact of the matter is the tiny little things necessary to keep the home computer optimized isn’t difficult at all. I’m not into a lot of physical activity anymore as age made me realize; the only thing that doesn’t hurt in the morning when I get out of bed is the eyelids. I don’t jog any longer and as far as I’m concerned; that animal the wife drug home 180 years ago – can give itself a walk.

I’m more into keeping the mind fit and dedicate myself into contemplating important things such as how many fish I’m going to drag home from the lake, if the dog is going to find its way home, how many Emails I’ll be sending or receiving and most importantly; why it is the TV volume is set at 24 and somehow comes on in the morning set somewhere around 38 or higher. I still don’t know who formats TV movies to specifically fit my television set and why anyone would want to take a prescription drug after listening to all the accompanying warnings the commercials render.

As you have guessed I’m not into massive physical activity and as such will not be taking the time to come over to your house to show you how to optimize your home computer. The tech boys at work are out bar hopping looking for their future wife and I know by now, your home computer is getting slower than a piss ant missing 3 or 4 legs down it’s right side. (I’m not an anthropologist). Anyway in between Emails, articles, electronic newspapers somewhere in the midst of my avid Internet surfing (which sounds physical) I actually discovered the solution to your home computer woes. I discovered (as you have) you didn’t need to buy all that fixit software above and beyond the antivirus stuff. All you need is a series of home videos that take you by the hand and teach you how to expertly optimize that little computer operating system with an hours worth of effort. Your computer will be up and running as if it was just plugged in today!
