History of Computers
History of Computers
- Z1 Computer. Developed in 1936 by Conrad Zuse, the first freely programmable computer served as an automatic calculator device with three elements: a control, a memory and a calculator for arithmetic. It used a punched tape reader as its output device instead of a monitor.
- ABC Computer. The first electronic-digital (binary) computer was developed by Atanasoff and Clifford Berry in 1942. It used parallel processing, regenerative memory and had a separation of memory and computing functions.
- Harvard Mark I Computer. Howard Aiken and Grace
Hopper developed this model in 1944. Imagine a giant room full of
noisy, clicking metal parts, 55 feet long and eight feet high. The
five-ton device contained almost 760,000 separate pieces.
- Manchester Baby Computer and the Williams Tube. Developed by Frederic Williams and Tom Kilburn in 1948, it used a type of altered cathode ray tube for a computer monitor. (Cathode ray tubes were also used for early television sets.)
- The Transistor was developed by John Bardeen, Walter Brattain and William Shockley in 1948. Although not a computer itself, it greatly assisted in their evolution by making them more stable electronically and cheaper to produce.
- UNIVAC Computer. Developed by John Presper Eckert and John Mauchley in 1951 for the Census Bureau, the device was also used commercially for payroll.
- IBM FORTRAN. John Backus developed the first successful high-level programming language in 1954.
- MICR (Magnetic Ink Character Recognition). This technology was developed for the bank industry in 1955 by Stanford Research Institute, Bank of America and General Electric to read the numbers at the bottom of checks.
- Integrated Circuit or "Computer Chip." Developed by Jack Kilby and Robert Noyce in 1958; placed the previously separated transistors, resistors, capacitors and all the connecting wiring onto a single crystal (or "chip") made of semiconductor material.
- Spacewar Computer Game. The first computer game was invented by Steve Russell and the Massachusetts Institute of Technology in 1962.
- Computer Mouse and Windows. In 1964, Douglas Engelbart of Stanford Research Institute created the mouse to use with the first graphical user interface, both his inventions.
- ARPAnet. The first internet was developed in 1969 by Charles M. Herzfeld.
- Intel 1103 Computer Memory. The world's first dynamic random access memory (RAM) chip was developed in 1970.
- Intel 4004 Computer Microprocessor was developed by Faggin, Hoff, and Mazor in 1971.
- The Floppy Disk was invented by Alan Shugart and IBM in 1971.
- Ethernet Computer Networking was developed by Robert Metcalfe and Xerox in 1973.
- First Consumer Computers. The first consumer computers were developed by IBM and Apple in the mid-1970s.
- MS-DOS Computer Operating System was developed by Microsoft in 1981.
- Laptop Computer. The PC Convertible, the first laptop sold to consumers, was developed by IBM in 1986. It weighed 12 pounds.
- 3.5-inch diskette. First produced by IBM in 1987.
- VGA Computer Screens. Introduced in 1987 by IBM, the Video Graphics Array is a display standard that provides 640 x 480 resolution that could display 16 colors at one time.
- Worm. A computer worm released onto ARPAnet in 1988, disabled about 6,000 computers.
- The World Wide Web. Launched to the public Aug. 6, 1991, the World Wide Web was developed by Tim Berners-Lee, a scientist at the European Partial Physics Laboratory (CERN) in Geneva, Switzerland. The year before he also developed the first hypertext system.

Why Upgrade Your Curre
LED TV: What to Look For
Buying an LED TV is no small purchase. It's important to know what to look for when shopping for a new TV. Your TV says a lot about who you are, so having an out-of-date television can give the wrong impression. It is the most visible piece of your home theater system and the only part that you actually see during a movie. While it is turned off it is very much a piece of your room’s décor, so slim design and a nice finish are essential. It is wise to consider these and other factors when selecting a new LED TV.
Features
Look for an LED TV with local dimming because, as with all electronics, not all TVs are created equally. The best LED TVs will actually be able to dim the backlight in dark portions of a movie, resulting in greater detail and contrast. LED backlights allow the TV to be built to a slimmer standard. This is especially important when mounting the TV to a wall, which is probably the most popular way to mount a TV.

This is especially important when mounting the TV to a wall, which is probably the most popular way to mount a TV.
Display
Look for a TV with a fast refresh rate. Standard TVs refresh at 60Hz, and the best LED TVs refresh at 240Hz or faster. You will also want to look for a TV with a response time of 3ms or faster. This will make those quick movements less blurry and improve gaming, sports and action movies. Because of the LED backlighting you will find TVs with a contrast ratio of up to 10,000,000:1, which is far beyond that of any LCD TV on the market.

Connections
Most high-end LED TVs will have at least four HDMI inputs as well as an Ethernet port, PC input and other standard component video inputs. Some may even include Wi-Fi or have a memory card slot for quick picture viewing.

Help & Support
Whenever you purchase anything online you will want to make sure the company offers plenty of help and support. Most companies will have a phone number, email, live chat, FAQs and even online manuals in case you lose the one that comes with your TV. Response times should be quick, and the person helping you should know the answers to your questions.nt TV to an LED TV?
Your current TV works just fine, so why replace it? Let's start with
contrast ratio. Standard LCD TVs aren’t known for excellent contrast
ratios since they use cold cathode fluorescent lamps (CCFLs) which can’t
be turned off while in use. This means they can’t produce rich dark
images because there is always light on the screen.
Anything slimmer than a standard cathode-ray tube (CRT) television used to be considered a slim TV. Today it seems anything over 4 inches thick is unacceptable. LED backlit TVs allow the manufacturers to produce TVs that are slimmer than ever before. With an LED TV, it is finally possible to hang your TV on the wall and actually have it look like a picture.
LED TVs such as the Sony Bravia XBR-55HX929, Samsung UN55C8000, or LG Infinia 55LW6500 offer brighter pictures and a better contrast ratio because of local dimming. The result is a slimmer TV that produces vibrant colors. Everything that you watch on an LED TV will look better than your old TV because of the new LED lights that are used to produce the image. From video games to chick flicks, you will see detail that has been there all along but was simply blurred or could not be produced on a standard LCD TV

Smartphones
Smart phones
Why Buy a Smartphone?
As a busy person, you know the importance of staying a step ahead of
your clients and your family. You probably know the feeling of being
tied to your desk or home so as not to miss that important email or
phone call and to maintain convenient access to essential
data—proposals, schedules, contact information, business news or the
stock market. However, thousands have newfound freedom using PDA-style smartphones designed
for business (and fun). These cellular devices trace their roots back
to the personal digital assistant or PDA. Originally used as
businessperson’s right hand to track important client information,
project statuses, and task lists, these devices have evolved into an
everyman’s (and woman’s) tool.
These cellular devices are much more than just cell phones; they provide instant access to the web. Whether you’re researching news to predict the stock market or looking for the perfect golf course on the weekend, you’ll find it on the net.
Many of these devices allow you to sync with your desktop computer. This means you can store, view, and work on documents directly on your handheld. You can also receive and respond to emails as they arrive in your inbox on your home computer with real-time push email.
These products can also serve as multimedia devices, so your entertainment goes with you. They can store and display pictures and videos of friends and family and even entire feature-length movies. Most can take pictures and capture video, but the most common multimedia function is the ability to play MP3s—sit back, relax, and enjoy your favorite tunes while traveling or during breaks.
Another perk of using one of these devices is the fairly recent development of third-party applications (or apps). These apps range from those geared toward hardworking business tasks to entertaining games and everything in between. With thousands of apps available to download in a range of prices, there’s sure to be something that will appeal.
