yes-- hit "start" then "programs" then "accessories" then "system tools" then "system restore" then click "next" & choose date you want it to restore back to so it will check history again. click "next again" & then "restart" so after that you can do "control/H" for history and it will be restored back to the date you chose to see the browsing history deleted.

they are used for "personal" use. you can use them to do what you want. talk on msn messenger things, download games, save music, whatever you feel like doing
The personal computer is used for everything from business to mmorpg games.
It is used in homes and offices.

The disadvantages of fifth generation computers have yet to be agreed upon, but many feel that they are two of its advantages: AI and the overall advanced technology. The addition of AI worries many due to the computers possibly becoming smart enough to replace humans altogether, and many people are becoming reliant on the advanced technology for tasks that they can do without computers.

Ada Lovelace is typically considered the first programmer. She corresponded with Charles Babbage, who is credited with the first attempt at a serious, general-purpose computer. Lovelace and Babbage lived in the 19th century. The programming language Ada, developed by the US Department of Defense but commonly used in many different contexts, is named in honor of Ada Lovelace.

Grace Hopper is commonly considered the founder of computer programming. Her language was called, "Autocode." She was the first to use the term compile to refer to translating a program into code that the computer can directly understand. She was actually predated by Konrad Zuse, a German who developed a language he called "Plankalkul". This language never impacted computer science to any degree, however, because Zuse was a German living in the time of World War II, and of course there was a huge divide between Germany and the rest of the world in that time.

Newer computers are similar to older computers. This is a very general question. Typically, newer computers have more memory, data storage, calculation power, and video rendering capabilities.

Seymour Cray, is credited with creating the first super computer. Seymour Cray's companies made the initial and only super computers for many years. Supercomputers now have tens of thousands of processors and are capable of solving problems extremely quickly.

== == * The true stats will never be known simply because it's divided into children from the ages of 5 - 12, teens and adults, plus work hours on a computer and laptops. * The average adult (for personal use only) spends 1 hour per day on the computer 2 - 3 hours of TV and 2 hours listening to the radio. This translates into one third of our waking hours. * AVERAGE TEENS: 4 hours 48 minutes per day not including schoolwork. Female teens spend as much time on the computer as male teens.

The word "computer" originally referred to a person who could do advanced math very quickly.

Later, the term was attached to the ENIAC (the first computer) which could do very advanced calculations in a short amount of time, but unfortunately occupied an entire gym-sized room.

The ENIAC led to the development of the Kenbak-1 (the first personal computer/calculator) and eventually to modern computers. Hence, the name was permanently attached to any device that could do advanced functions.

As this development took place, more tasks could be accomplished by computers including --but not limited to-- the storage, transfer, and viewing of information, playing games, and communication.

Computers are now used in many locations for specific purposes:

* On your desktop or lap * In planes, cars, trains, and other methods of transportation * In our home and cell phones

* In anything that has a screen * In satellites and other space craft (manned and unmanned)

2) Companies now market more products worldwide.

input- we ask the computer what to do ( with the help of input devices)

output- computer shows the result for what we have asked him (by screen)

in a computer basic part is CPU

in a CPU basic parts are

BIOS which start the computer

harddisk which store data

process which process the data

The American Bell XS-1 rocket aircraft, piloted by Captain Charles (Chuck) Yeager on 14 October 1947. He reached Mach 1.015 (1,078 km/h; (670 mph) at a height of 12,800 m (42000 ft) over Lake Muroc, California, USA. To be technically correct, Chuck Yeager set the record in level flight. There were probably many aircraft that broke the sound barrier in a dive---usually a crash dive. But no one recorded their feat.

it is concern that booting in computer signifies when the computer's power is switched on control is transferred by hardware to the bootstrap procedure of BIOS in ROM. The bootstrap procedure carries out some hardware tests to check whether the memory and other hardware devices are functioning properly.

Technology is the foundation of globalization. Without the participation of technology, this process would not be possible. Technological advances made ​​it possible contacts between people living in different parts of the world. Modern tools of communication and transport allow companies to conduct business not only locally but also globally.

The function of a mainframe computer is usually as a large database of all sorts of data. An example would be a large credit card company would have a computer that would hold every bit of data that company needed including customers and their info. So in short a computer with large amounts of data, and in most cases, backups of that data too.

Not exactly what you've asked, but anyway: December 1991 I purchased in Perth at Myers an Amstrad 286 PC, for about $1900 Australian. It had a 40Mb HDD, 16Mhz CPU, 14 inch monitor, and a five and an a quarter plus a three and half FDD, and about one or two Meg RAM if I recall correctly.

You likely are thinking of IBM, Intel, and Apple, to name a few.

This is a very difficult question because it's unclear how large of a scale that you are talking about. Some of the biggest (not necessarily the best) companies on the market today are Compaq/Hewlett Packard, Dell, and Toshiba. Those are probably the biggest on the market today. Depending on what type of things you will be doing on the computer itself is what you will actually need to be looking at.

it has an efficient and effective control over human error.it saves a lot of time. it also serves as a useful tool for fast communication through e-mails, chatting etc,.it is possible to calculate or summarize quantitative information.

The anwers is not avalible!!

1. You can look up information.

2. You can view movies and pictures.

3. You can type a piece of writing.

4. You can order things through internet.

5. You can send information.

The first computer was an Chinese abacus.

A computer is defined as A device that computes that assembles, stores, correlates, or otherwise processes information.

An abacus is a manual computing device consisting of a frame holding parallel rods strung with movable counters.

Word History: The adjective dusty, with its connotations of disuse and age, might seem an appropriate word to describe the abacus, since this counting device was used for solving arithmetical problems in the days before calculators and computers. Originally the abacus was, in fact, dusty. The source of our word abacus, the Greek word abax, probably comes from Hebrew 'bq, "dust," although the details of transmission are obscure. In postbiblical usage 'bq meant "sand used as a writing surface." The Greek word abax has as one of its senses "a board sprinkled with sand or dust for drawing geometric diagrams." This board is a relative of the abacus with movable counters strung on rods that is familiar to us. The first use of the word abacus, recorded in Middle English in a work written before 1387, refers to a sand-board abacus used by the Arabs. The difference in form between the Middle English word abacus and its Greek source abax is explained by the fact that Middle English borrowed Latin abacus, which came from the Greek genitive form (abakos) of abax.

The first scanner for computers was introduced in the year 1957. It was a drum scanner that was designed by Russell A. Kirsch.
