Memory

A memory is just like a human brain. It is used to store data and instructions. Computer memory is the storage space in the computer, where data is to be processed and instructions required for processing are stored. The memory is divided into large number of small parts called cells. Each location or cell has a unique address, which varies from zero to memory size minus one. For example, if the computer has 64k words, then this memory unit has 64 * 1024 = 65536 memory locations. The address of these locations varies from 0 to 65535.

Memory is primarily of three types −

1.Cache Memory

2.Primary Memory/Main Memory

3.Secondary Memory

1.Cache Memory

Cache memory is a very high speed semiconductor memory which can speed up the CPU. It acts as a buffer between the CPU and the main memory. It is used to hold those parts of data and program which are most frequently used by the CPU. The parts of data and programs are transferred from the disk to cache memory by the operating system, from where the CPU can access them.

Advantages

▫️Cache memory is faster than main memory.

▫️It consumes less access time as compared to main memory.

▫️It stores the program that can be executed within a short period of time.

▫️It stores data for temporary use.

Disadvantages

▫️Cache memory has limited capacity.

▫️It is very expensive.

2.Primary Memory (Main Memory)

Primary memory holds only those data and instructions on which the computer is currently working. It has a limited capacity and data is lost when power is switched off. It is generally made up of semiconductor device. These memories are not as fast as registers. The data and instruction required to be processed resides in the main memory. It is divided into two subcategories RAM and ROM.

Characteristics of Main Memory

🔹️These are semiconductor memories.

🔹️It is known as the main memory.

🔹️Usually volatile memory.

🔹️Data is lost in case power is switched off.

🔹️It is the working memory of the computer.

🔹️Faster than secondary memories.

🔹️A computer cannot run without the primary memory.

3.Secondary Memory

This type of memory is also known as external memory or non-volatile. It is slower than the main memory. These are used for storing data/information permanently. CPU directly does not access these memories, instead they are accessed via input-output routines. The contents of secondary memories are first transferred to the main memory, and then the CPU can access it. For example, disk, CD-ROM, DVD, etc.

Characteristics of Secondary Memory

🔹️These are magnetic and optical memories.

🔹️It is known as the backup memory.

🔹️It is a non-volatile memory.

🔹️Data is permanently stored even if power is switched off.

🔹️It is used for storage of data in a computer.

🔹️Computer may run without the secondary memory.

🔹️Slower than primary memories.

 Printers

Printer is an output device, which is used to print information on paper.

There are two types of printers -

1. Impact Printers

2. Non-Impact Printers

1. Impact Printers

Impact printers print the characters by striking them on the ribbon, which is then pressed on the paper.

Characteristics of Impact Printers are the following −

▫️Very low consumable costs

▫️Very noisy

▫️Useful for bulk printing due to low cost

➡️There is physical contact with the paper to produce an image

These printers are of two types −

1. Character printers

2. Line printers

1. Character Printers

Character printers are the printers which print one character at a time.

These are further divided into two types:

Dot Matrix Printer(DMP)

Daisy Wheel

Dot Matrix Printer

In the market, one of the most popular printers is Dot Matrix Printer. These printers are popular because of their ease of printing and economical price. Each character printed is in the form of pattern of dots and head consists of a Matrix of Pins of size (5*7, 7*9, 9*7 or 9*9) which come out to form a character which is why it is called Dot Matrix Printer.

Advantages

▫️Inexpensive

▫️Widely Used

▫️Other language characters can be printed

Disadvantages

▪️Slow Speed

▪️Poor Quality

Daisy Wheel

Head is lying on a wheel and pins corresponding to characters are like petals of Daisy (flower) which is why it is called Daisy Wheel Printer. These printers are generally used for word-processing in offices that require a few letters to be sent here and there with very nice quality.

Advantages

▫️More reliable than DMP

▫️Better quality

▫️Fonts of character can be easily changed

Disadvantages

▪️Slower than DMP

▪️Noisy

▪️More expensive than DMP

2. Line Printers

Line printers are the printers which print one line at a time.

These are of two types −

Drum Printer

Chain Printer

Drum Printer

This printer is like a drum in shape hence it is called drum printer. The surface of the drum is divided into a number of tracks. Total tracks are equal to the size of the paper, i.e. for a paper width of 132 characters, drum will have 132 tracks. A character set is embossed on the track. Different character sets available in the market are 48 character set, 64 and 96 characters set. One rotation of drum prints one line. Drum printers are fast in speed and can print 300 to 2000 lines per minute.

Advantages

▫️Very high speed

Disadvantages

▪️Very expensive

▪️Characters fonts cannot be changed

Chain Printer

In this printer, a chain of character sets is used, hence it is called Chain Printer. A standard character set may have 48, 64, or 96 characters.

Advantages

▫️Character fonts can easily be changed.

▫️Different languages can be used with the same printer.

Disadvantages

▪️Noisy

2. Non-impact Printers

Non-impact printers print the characters without using the ribbon. These printers print a complete page at a time, thus they are also called as Page Printers.

These printers are of two types −

1. Laser Printers

2. Inkjet Printers

• 
  

• 
  

Laser Printers

These are non-impact page printers. They use laser lights to produce the dots needed to form the characters to be printed on a page.

Advantages

▫️Very high speed

▫️Very high quality output

▫️Good graphics quality

▫️Supports many fonts and different character size

Disadvantages

▪️Expensive

▪️Cannot be used to produce multiple copies of a document in a single printing

Inkjet Printers

Inkjet printers are non-impact character printers based on a relatively new technology. They print characters by spraying small drops of ink onto paper. Inkjet printers produce high quality output with presentable features.

They make less noise because no hammering is done and these have many styles of printing modes available. Color printing is also possible. Some models of Inkjet printers can produce multiple copies of printing also.

Advantages

▫️High quality printing

▫️More reliable

Disadvantages

▪️Expensive as the cost per page is high

▪️Slow as compared to laser printer

 

Monitors

▫️Monitors, commonly called as Visual Display Unit(VDU), are the main output device of a computer. It forms images from tiny dots, called pixels that are arranged in a rectangular form. The sharpness of the image depends upon the number of pixels.

▫️There are two kinds of viewing screen used for monitors.⤵️

• 1.Cathode-Ray Tube (CRT)
• 2.Flat-Panel Display
• 
  

1.Cathode-Ray Tube (CRT) Monitor

▫️The CRT display is made up of small picture elements called pixels. The smaller the pixels, the better the image clarity or resolution. It takes more than one illuminated pixel to form a whole character, such as the letter ‘e’ in the word help.

▫️A finite number of characters can be displayed on a screen at once. The screen can be divided into a series of character boxes - fixed location on the screen where a standard character can be placed. Most screens are capable of displaying 80 characters of data horizontally and 25 lines vertically.

▫️There are some disadvantages of CRT −

• 🔹️Large in Size
• 🔹️High power consumption
• 
  

2.Flat-Panel Display Monitor

▫️The flat-panel display refers to a class of video devices that have reduced volume, weight and power requirement in comparison to the CRT. You can hang them on walls or wear them on your wrists. Current uses of flat-panel displays include calculators, video games, monitors, laptop computer, and graphics display.

▫️The flat-panel display is divided into two categories −

• 🔸️Emissive Displays − Emissive displays are devices that convert electrical energy into light. For example, plasma panel and LED (Light-Emitting Diodes).

• 🔸️Non-Emissive Displays − Non-emissive displays use optical effects to convert sunlight or light from some other source into graphics patterns. For example, LCD (Liquid-Crystal Device).

Types of Keyboard ⌨

Types of keyboards

Most computer users use the standard keyboard, which connects to the computer. Although there are many types of a computer keyboard, such are as follows:

1. Flexible keyboard: 

It is a type of keyboard that is made of soft silicone with highly portable. It is water and dust-resistant and does not require constant cleaning. It acts the same as a standard keyboard and connects to the computer via a USB connection serial port. These types of keyboards can also be more durable in terms of some ways, as compared to a traditional keyboard.

The flexible keyboard is made of soft silicone that saves it from a number of different substances. For instance, if you use the keyboard near the liquid spaces, the silicone skin provides excellent protection against spills. Furthermore, it does not make a sound when being used; that's why it is also called a silent keyboard. These keyboards are useful for traveling time because they can be rolled up into a bag and flexible in outdoorsy situations.

2. Ergonomic Keyboard: 

This type of keyboard is beneficial for your body posture. Instead of adjusting yourself to fit the keyboard, it is designed to fit you easily, ease of use, and reduce strain. It is designed in that way; instead of bending their hands, it allows users to straight their hands. Generally, the space-bar is bigger as compared to a regular keyboard, which allows for fast typing.

3. Wireless Keyboard:

 It is a computer keyboard that is connected to computers, laptops, or tablets without any cables. It uses radio frequency (RF), infrared (IR), or Bluetooth technology to connect with devices. Users can move the wireless keyboard around without having to put it on a desk as it provides portability and flexibility to the users. It is designed by stainless steel material that increases its life for a long time. It can set up very easily by plugging the USB receiver into the computer.

It utilizes light waves to transmit signals to other infrared-enabled devices as it is based on infrared technology. Some wireless keyboards use radio frequency technology, which communicates via signals with a range from 27 MHz to up to 2.4 GHz.

4. Mechanical Keyboard: 

It is made with high quality that commonly used in both home and office. It is designed for long life with high durability and responsiveness. It provides crisp click sound, medium resistance, and better feedback for gaming performance and ultimate typing. It offers framing, switches, type print methods, functionality, PCB board, key construction, LED lighting, or more other better features as compared to traditional rubber dome keyboards.

5. Virtual Keyboard: 

It is a software-based keyboard that enables users to type without the need for physical keys. It is an alternative for a physical keyboard or a digital representation of a QWERTY keyboard. These types of keyboards commonly have many pages of characters, including numbers, letters, punctuation, and symbols. Some virtual

keyboards also include options to insert emojis, stickers, or animated GIFs on the basis of the device's operating system. The devices that contained virtual keyboard are tablets, smartphones, and other portable devices, because these devices do not require the constant use of a physical keyboard.

Examples of virtual keyboards

Gboard: Google created a virtual keyboard for Android and iOS that includes features like GIFs, customizable themes, and translation capabilities.

OSK: It stands for an on-screen keyboard. It is commonly found in Microsoft Windows.

6. Projection Keyboard:

 It is a form of computer input device that can be connected via Bluetooth to the mini PC, tablet computer, or even smartphone. In projection keyboard, the image of a virtual keyboard is projected onto a surface. The device records the corresponding keystroke when a user touches any key from the shown keyboard on the surface. Some devices are connected via Bluetooth devices such as tablets, smartphones, mini-PC with Android, Windows operating system or iOS, etc.

7. Gaming Keyboard: 

A keyboard that contains a few specific keys used for gamers is known as a gaming keyboard. The W, S, D, A, and arrow keys are widely used for games on the standard QWERTY keyboard. Gaming keyboards (mostly mechanical keyboard), the key switches needless depression that provides faster action for games.

Invention of Keyboard♒

Invention of the first keyboard

There were different types of invention, as well as the typewriter, keypunches, and teleprinters that helped to develop the computer keyboard. In the 1700s, the first writing devices were designed, and Henry Mills filed patented in London, England, in 1714.

Invention of the typewriter

The different typing and writing devices were created around the world in the late 1700s and the beginning of the 1800s. Although, in 1868, Christopher Sholes developed and patented the first practical typewriter and the word Type-Writer that is considered to be the first typewriter.

Additionally, the QWERTY keyboard design was introduced by the Type-Writer, which is still

mainly used on US keyboards today. Samuel W. Soule, Christopher Sholes, and Carlos Glidden created a Type-Writer that picture shown in the below:

In 1878, the first keyboard with a Shift key was invented that had one Shift key on the left side of the keyboard. The Underwood typewriter is considered the first successful modern typewriter, till 1939, five million of its typewriters were sold. The first Underwood typewriter was invented by Franz Xaver Wagner, and on 27 April 1893, he filed to patent the typewriter U.S. patent 523,698. The biggest improvement of Underwood typewriter, it was capable of seeing the writing it was typed. Later in 1895, Franz Xaver Wagner created the Underwood company with the help of John Underwood and introduced its first typewriter in 1896.

Before introducing the IBM Selectric typewriter by IBM on 27 July 1961, typewriters from all manufacturers began to become more alike. Unlike other typewriters, the IBM Selectric typewriter used a typeball, which containing characters that would strike an ink ribbon. Furthermore, this typewriter was sold more than 13 million until 1986.

The invention of keypunch, the telegraph, and teleprinter

Joseph Marie Jacquard developed the Jacquard Loom in the late 1700s, which was expanded by Herman Hollerith with his keypunch inventions in the late 1800s and the beginning of the 1900s.

In 1832, Pavel Schilling invented the first electrical telegraph and to send Morse code messages over a line, allowing for a single key to be used. Later in 1846, a printing telegraph was patented by Royal Earl House, which used 28 piano-style keys. The keys made it easy to send messages by representing each letter in the alphabet. In 1874, the Baudot code was invented by Emile Baudot; later, it was extended by Donald Murray (inventor of thetelegraphic typewriter). Charles Krum helped invent the teleprinter by working to continue on Frank Pearne that was developed from 1902 to 1918. In August 1907, he filed patent U.S. patent 862,402. Also, he filed patent 888,335 in May 1908, and patent 1,286,351 in May 1910.

Early computers with keyboards

After many years, in 1964, the introduction of Multics and video display terminals (VDTs), which enabled users to see typing on the screen what they are typing.

The DataPoint 3300 began to ship by the Computer Terminal Corporation in 1969. It was the first computer terminal designed to replace the teleprinter. Some other versions of this terminal were also introduced as well as HP 2600A, DEC, and VT06. The DataPoint 3300 was a terminal that was able to move the cursor using arrow keys, and it used a screen display to show typed text. Also, it had the ability to clear all text on the screen.

At the beginning of the 1970s, keyboards began to use what we use today. Those keyboards were heavy mechanical or reconstructed electric typewriters from companies such as IBM. Apple, Radio Shack, and Commodore introduced their computers in the late 1970s that come included keyboards. Later, IBM PC and the Model F keyboard introduced by IBM in August 1981.

The Model M keyboard was introduced by IBM in 1986, which contained function keys like today's keyboards have across the top of the keyboard. The Model M is still considered a high keyboard as it has a standard US layout with 101-key, which is used for full-sized keyboards today. It is also designed for windows keyboards that have 104-key with the Menu keys and windows keys.

Since IBM introduced the Model M keyboard, many changes have been in the keyboard that is in use today. A membrane helps to manufacturer computer keyboards easily and reduce manufacturing costs. Furthermore, the membrane keyboard makes the keyboard lighter, thinner, and quieter as compared to the first mechanical keyboards.

What Is Keyboard ?

 KEYBOARD

A keyboard is a peripheral device that enables a user to input text into a computer or any other electronic machinery. A keyboard is an input device and is the most basic way for the user to communicate with a computer.

A keyboard is one of the primary input devices that allows users to input text into a computer or any other electronic machinery. It is a peripheral device that is the most basic way for the user to communicate with a computer. It consists of multiple buttons, which create numbers, symbols, and letters, and special keys like the Windows and Alt key, including performing other functions. The design of the keyboard comes from the typewriter keyboards, and numbers and letters are arranged on the keyboard in that way, which helps to type quickly.

The above keyboard design is called QWERTY design because of its first six letters across in the upper-left-hand corner of the keyboard. Although the keyboard design is derived from the typewrites, nowadays, it also includes many other keys as well as Alt/Option, Control, and Windows key can be used as shortcuts to perform the particular operation by combination with other keys. For example, if you press Control + S while working on a document in Microsoft Word, it will save the document you are working on. Furthermore, most of the keyboards have function keys (F1 to F12 or F16) at the top of the keyboard and arranged arrow keys in the downside used to perform numerous functions.

There are many type of keyboard in today's world. That we have to see in next BLOG.

 COMPUTER

A computer is a programmable device that stores, retrieves, and processes data. The term "computer" was originally given to humans (human computers) who performed numerical calculations using mechanical calculators, such as the abacus and slide rule. The term was later given to mechanical devices as they began replacing human computers. Today's computers are electronic devices that accept data (input), process that data, produce output, and store (storage) the results (IPOS).

Computer overview

Below is a picture of a computer with each of the main components. You can see the desktop computer, flat-panel display, speakers, keyboard, and mouse in the picture below. We've also labeled each of the input devices and output devices.

History of the computer

The first digital computer and what most people think of as a computer was called the ENIAC. It was built during World War II (1943-1946) and was designed to help automate the calculations being done by human computers. By doing these calculations on a computer, they could achieve results much faster and with fewer errors.

Early computers like the ENIAC used vacuum tubes and were large (sometimes room size) and only found in businesses, universities, or governments. Later, computers began utilizing transistors and smaller and cheaper parts that allowed the ordinary person to own a computer.

How are computers used today?

Today, computers do jobs that used to be complicated much simpler. For example, you can write a letter in a word processor, edit it anytime, spell check, print copies, and send it to someone across the world in seconds. All these activities would have taken someone days, if not months, to do before. Also, these examples are a small fraction of what computers can do.

What components make up a desktop computer?

Today's desktop computers have some or all the components (hardware) and peripherals below. As technology advances, older technologies, such as a floppy disk drive and Zip drive (shown below), are no longer required or included.

Optical drive: Blu-ray, CD-ROM, CD-R, CD-RW, or DVD.

CPU (processor)

Floppy disk drive

Hard drive

Keyboard

RAM (random access memory)

Microphone

Monitor, LCD, or another display device.

Motherboard

Mouse

Network card

Power Supply

Printer

Sound card

Speakers

Video card

Wearable

What parts are needed for a computer to work?

A computer does not require all the components mentioned above. However, a computer cannot function without having at the very minimum the parts listed below.

Processor - Component that executes instructions from the software and hardware.

Memory - Temporary primary storage for data traveling between the storage and CPU.

Motherboard (with onboard video) - Component that connects all components.

Storage device (e.g., hard drive) - Slower secondary storage that permanently stores data.

However, if you had a computer with only the minimum parts above, you would be unable to communicate with it until you connected at least one input device (e.g., keyboard). Also, you would need at least one output device (e.g., monitor) for you to see what is happening.

Computer connections

All computers have different types of connections. An example of the back of a personal computer and brief descriptions of each connection is found on our computer connections page.

Types of computers

Computers can be classified as one of three types of computers: a general-purpose computer, special-purpose computer, or specialized computer.

A general-purpose computer is what most people think of when thinking about a computer and is what this page covers.

A special-purpose computer is embedded in almost all electronic devices and is the most widely-used computer. This computer is designed for a specific task and is found in ATMs, cars, microwaves, TVs, the VCR, and other home electronics. See our special-purpose computer page for further information and examples.

A specialized computer is like a general-purpose computer but is designed only to perform one or a few different tasks. See our specialized computer for further information and examples of these computers.

When talking about a computer or a "PC," you're usually referring to a desktop computer found in a home or office. However, the lines of what makes these computers are blurring. Below are different examples of what's considered a computer today.

The picture above shows several types of computers and computing devices and is an example of their differences. Below is a complete list of general-purpose computers of past and present.

Who makes computers?

Today, there are two types of computers: the PC (IBM compatible) and Apple Mac. Many companies make and build PCs, and if you get all the necessary parts for a computer, you can even build a custom PC. However, with Apple computers, only Apple designs and makes these computers. See our computer companies page for a listing of companies (OEMs) that make and build computers.

Thank You🙂

What Is Laptop💻

 What is a laptop?

A laptop, sometimes called a notebook computer by manufacturers, is a battery- or AC-powered personal computer (PC) smaller than a briefcase. A laptop can be easily transported and used in temporary spaces such as on airplanes, in libraries, temporary offices and at meetings.

A laptop can be turned into a desktop computer with a docking station, which is a hardware frame that supplies connections for peripheral input/output devices such as a monitor, keyboard and printer.

 5 Things to Consider When Buying Headphones 🎧

FREE SHIPPING (U.S. Only) ON ORDERS 

Are you on the market for a new pair of headphones or earbuds? If you haven’t purchased any lately, you might be surprised to see all the options. Truly, the marketplace is filled with variety — and confusion.

To help you get a better sense of what to look for in your next pair of earbuds or headphones, we’ve created a down-to-earth headphone buying guide. Get started on the path to the perfect headphones with a little help on buying tips and hints.

1. Would Wired or Wireless Be Better?

Some people love to have the freedom of wireless earbuds and headphones. Others prefer having units that connect to their iPhones or other devices. While one won’t necessarily outperform the other, wireless models do tend to be very convenient. However, you should realize that with wireless earbuds, you’ll need to carefully store them so they aren’t separated.

2. Do You Care About Bass and Treble Balance?

Is sound quality important to you? Do you like to hear music that sounds as if it’s being played right in front of you? If so, you might want to check out the balance between the bass and treble on earbuds and headphones. Some of the higher-end models might even allow you to balance sounds yourself, offering you the luxury of being able to tune your music precisely to your liking.

3. What Style Feels Most Comfortable?

You’re going to be wearing your earbuds and headphones during activities, so they should be downright comfortable. Ideally, you shouldn’t be able to tell that you have them in. This necessitates getting a proper fit. Some people like to have earbuds that are customized and fit directly into the opening of the ear. As long as they are built to your individual ear, they won’t fall out.

Other people like to have over-ear models for the security. Neither one is a more logical style. The choice comes down to personal preference.

4. Are Looks or Brand Important?

Some models of headphones and earbuds are meant to completely impress. Usually, these have stylish elements or are made by a particular brand. Of course, you should always research possibilities before buying, but you may want to lean toward fashion or appearance if you want something that stands out or you’re loyal to one company.

5. What is Your Budget?

Finally, we come to one of the biggest factors: Price. You’ll be astonished when you realize the gap between the lowest and highest prices for headphones and earbuds. Sure, you need to go with something in your budget, but beware of products that seem too cheap. They usually won’t work well and will need to be replaced rapidly, making them much less of a deal than you thought.

Learning how to buy the right headphones or earbuds takes a little practice. Be sure to keep your receipts and have an understanding of manufacturer’s warranties, just in case you choose something that turns out to be a dud. That way, you can get your money back and start again.
