History of the Computer Printer

Here’s a bit of background into the history of the printer.

The first computer printer

The first high-speed, non fluid printer was manufactured in the early fifties, by Remington Rand. This printer was used in combination with the UNIVAC computer. It was essentially an evolved form of the electric typewriter, and the same ‘typing’ mechanism was used in these printers, but the actual printing was directed by the computer, instead of fingers.

The laser printer

A type of dry printing press, initially called electro-photography, was invented by Chester Carlson, in 1938. This system was later called xerography. It became the basis for the laser printer technology that we know today. In 1975, the IBM 3800 laser technology made it possible to print text and high quality graphics onto paper.

The dot-matrix printer

In 1970, Digital Equipment Corporation produced the first dot-matrix printer, the LA30, which was able to print 30 characters per second. Improvements to speed and usability followed the same year when

Wireless Keyboard

A work desk that is full of clutter and loose wires can be hazardous, not to mention very annoying. You can easily get confused with all the wires and have problems identifying each of the gadget connector. But thanks to technology, we now have wireless keyboards which tackles this problem.

The wireless keyboard actually looks like the same as a standard keyboard. The only difference is that the latter uses infra-red beams to transmit typed data to the computer.

Merriam Webster define infrared rays as electromagnetic radiation with a longer wave length than light but shorter when compared to radio waves. The computer has a radio frequency receiver or a Bluetooth antenna which receives the data transmitted to it by the keyboard. When using the wireless keyboard, it ought to be placed in such a way that the receiver is within range of the infrared beam.

There are certain advantages and disadvantages with wireless keyboards. The most common advantage would be the reduced clutter and increased amount of space. Many of us can imagine wishfully what our home tables or office

The First Computer

The history of computers is very interesting and colorful. If you want to know who made the first computer, then read further to know more.

The answer to the question who made the first computer in the world, is not an easy one. There was never a perfect computer developed like the one which we are using today. It developed gradually and with combined efforts, the perfect machine was made. Hence a single person cannot be given the credit of making the modern computer. However, Charles Babbage is known to have conceived the idea of the computer first. Hence, he is also known as the ‘Father of Computers’.

The First Computer

Charles Babbage was a British math professor. It was he who thought of building an analytical engine, which was the first mechanical computer which could store programs. It was in the year 1837, almost 100 years before the origin of computers. It is really extraordinary for a person to think of building a machine which was way ahead of its time. But then, unfortunately, the analytical machine was never completed because of

Ways Choosing the Most Competent Computer Technician

Processor- What it’s ?

The processor, or the CPU (Central Processing Unit), is typically thought of as the brain of the computer. It controls all of the processes done through the computer. The processor of a computer is the hardware within a computer that carries out the instructions of a computer program. It does this by performing the basic arithmetical, logical, and input/output operations of the system. The overall fundamental operation of most CPUs is to execute a sequence of stored instructions called a program. These instructions are kept in some kind of computer memory.

There are two typical components to all CPUs. These are the Arithmetic Logic Unit (ALU) and the Control Unit (CU). The ALU performs arithmetic and logical operations, while the CU extracts instructions from memory and decodes and executes them. The CU will call on the ALU whenever necessary.

There are four steps to just about every CPU: fetch, decode, execute, and write back. During the first step, fetch, an instruction is retrieved from program memory. Next, during the decode step, that instruction is broken up into parts that have significance to other parts of the CPU. Then, various portions of the CPU are connected so
