How is a laptop different from a desktop?

                           

Because laptops are designed for important differences between portability, as well as their and desktop computers. A laptop has an all-in-one design, with a built-in monitor, keyboard, touchpad (instead of the mouse), and speakers. This means that it is fully functional, even when not connected to its peripherals. Build a laptop faster and have fewer ways to get cable. Some newer laptops even have a touch screen, so you may not even need to use a keyboard or mouse.

There is a connection to a conventional mouse, select a larger display, and other peripherals. This is basically your laptop into a desktop computer, there is one major difference: You can easily disconnect peripherals, and took a laptop, wherever you go.

Here, you can use a laptop expect major differences.

Laptop touchpad

AC adapter into the notebook

Touchpad: The touchpad, also known as the touchpad is a touch-sensitive pad that lets you use your finger to control cursor movement by drawing. Many touchpad now includes multi-touch gestures, which allows you to perform specific tasks with multiple finger gestures. E.g., a pinch gesture is often used to zoom in or out.

Battery: Every laptop has a battery that lets you use the laptop when it is not plugged in whenever you plug in a laptop, the battery charging. Another benefit of having a battery is that it can provide backup power to the laptop, if the power is off.

AC adapter: a laptop computer is often called a dedicated AC adapter power cord, which aims to use a specific type of laptop. Some MagSafe magnetic connector cable used to secure the withdrawal, if someone tripping over the power cord. This helps prevent damage to cables and laptops.

Port: Most portable computers are desktop computers have the same type of ports (such as USB), although they usually have fewer ports, to save space. However, some ports may be different, and they may need to use an adapter. For example, the monitor port is usually a Mini DisplayPort, which is normal for a smaller version of DisplayPort.

Computer - How to Buy?

                                  

Monitor

Size - This is the diagonal size of the LCD screen. The larger the area, the greater the image screen. A larger screen is the best movies and games. This will increase productivity.

Resolution - This is the number of pixels on the screen. For example, a 24-inch display is 1920 × 1200 (length x width) and 22-inch display, is 1680 × 1050. High resolution provides better picture quality and a good game experience.

Operating system

Everything is a computer operating system in some form or other major software running on it.

There are three main options: Windows, Linux, Apple OS X.

Linux is free, but people generally do not use it for domestic purposes.

Apple OS X only on Apple's desktop.

Windows 7 desktop users are very popular.

The recent launch of Windows 8, and in the market.

Windows 8 Windows 7 and all the starters, Home Basic, Home Premium, Professional, Ultimate, and multiple versions of the Enterprise Edition.

Memory

RAM is considered a computer memory as the computer's performance is directly proportional to its memory and processor.

Today's software and operating systems that require high memory.

Currently used in RAM DDR 3 1066 MHZ work

Press Windows 7 in, 1 GB RAM is the minimum normally required.

Recommended - 4 GB.

Hard Drive

Hard disk is used for storage purposes. Higher capacity, more data can be stored inside.

Now, one day the computer is equipped with a 500 GB hard drive, expandable to 2 TB.

In most desktop hard drive running at 7200 RPM speed standard performance.

Recommended - 500 GB.

CPU

Frequency (GHz) - which determines the speed of the processor. More speed, better CPU.

Core - Now-a-days are equipped with more than one CPU core, it's like there is on the computer has multiple CPU. Programs can take advantage of multi-core environment to run faster on this machine.

Brand - Intel or AMD. Both are equivalent. Intel in the lead.

Cache - higher L 1, L 2 cache, better CPU performance

Recommended - Intel Core i 3 i 3-32253.30 GHz processor.

Relationship between Hardware and Software

Hardware and software are dependent on each other. They must work together to make a computer to produce useful output.

Software is inseparable from the use of hardware support.

Hardware does not have a program operation can not be used, is of no use.

To obtain complete specific tasks on your computer, related software should be loaded into the hardware

The hardware is a one-time fee.

Software development is very expensive and is an ongoing expense.

Different software applications can be loaded in a different job to run on the hardware.

Software acts as an interface between the user and the hardware.

If the hardware is the computer system of the "heart", then the software is its "soul." Both are complementary to each other.

Computer - Internet and Intranet

Internet

It is a worldwide system that has the following characteristics:

Internet is a network of interconnected computer networks worldwide / global system.

Internet using standard Internet Protocol (TCP / IP) of

Each computer on the Internet is identified by a unique IP address.

The IP address is (eg 110.22.33.114) identifies the location of the computer a unique set of numbers.

A special computer's DNS (domain name server) is used to give names to IP addresses, so that the user can search through a computer name.

For example, DNS server resolves the name http://www.smallshopper.net.com to a specific IP address uniquely identifies this web hosting computer.

Each user can have access to the Internet worldwide.

Intranet

Intranet is a system of more than one PC connected to each other.

In computer intranet are not available to the world outside of the internal network.

Typically, each company or organization has its own Intranet network and membership / that company employees can access their internal computer networks.

Each computer in the Intranet is also identified as an IP address is a computer in the LAN is unique.

Computer - Operating System

It is a program with the following features:

An operating system is a program that, as between the software and computer hardware interfaces.

It is a set of integrated, specially planned for the overall management of resources and computer operations.

It is the control and monitoring reside on a computer, including application programs and other system software of all other programs dedicated software executed.

Operating system goals

Causing the computer system to facilitate an efficient way to use

To hide the hardware details from the user's resources

Provides the user interface to the computer system convenient to use

It easier for users to access and use as an intermediary between other hardware resources and its users and make it

Resources to manage computer systems

In order to track what resources to use, who granted the requested resource is based on the use of resources and mediation programs and users of different conflicting demands

In order to provide users and programs between efficiency and equity of resource sharing

Computer Network

What is a computer network?

Where in the computer network is a plurality of computers are connected to each other, in order to share information and resources of the system.

Characteristics of computer networks

Shared resources from one computer to another

Files created, and store them on a computer, to access these files from another computer over a network connection (s) Printer, scanner or fax machine connected to a computer network, allowing the network to other computers through a network of machines.

The following is the hardware needed to set up a computer network list.

Network Cable

Distributors

Router

Built-in network card

Network Cables

Network cables are used to connect computers. The most commonly used cable is Category 5 cable rj-45.

Distributors

A computer can be connected via the serial port to another one, but if we need to connect multiple computers to generate a network, the serial connection will not work. The solution is to use a central agency, which other computers, printers, scanners, etc. can be connected, then the agency will manage or distribute network traffic.

Router

A router is a device acts as the type of computers and other devices are part of a network, wherein the center point. Router is equipped with a hole called port and the computer, and connect to other devices using a network cable router. Now give the day a router to use this computer may not have any physical cable connection in wireless mode.

Computer - Software

Software is a set of programs, which are designed to perform a well-defined function. A program was written to solve a specific problem sequence of instructions.

There are two types of software

System Software

Application software

System Software

System software is a collection of design, operation, control and extend the processing power of the computer program itself. System software is usually manufactured by computer. These software products include low-level language for writing programs, and hardware at a very basic level of interaction. System software as the interface between the hardware and the end user.

Some examples of system software is the operating system, compiler, translator, assembler, and so on.

Application software

The characteristics of the system software as follows:

Shut down the system

Fast

Difficult to design

Difficult to understand

Less interaction

Smaller size

Difficult to operate

Generally written in low-level language

Application software

Application software products are designed to meet the specific needs of the environment in particular. All software applications in the computer lab can be included in the preparation of the application software category.Applications may include a single program, such as a Microsoft Notepad for writing and editing simple text. It can also be set by the program, commonly referred to as a package, which together to complete a task, such as a spreadsheet package.

Examples of applications are the following:

Microsoft Office Suite software

Microsoft Word

Microsoft Excel,

Microsoft Powerpoint

Computer Ports

Computer - Read Only Memory

On behalf of read-only memory ROM. From which we can only read, but can not write memory on it. This type of memory is non-volatile. In the manufacturing process information is permanently stored in memory such as. A ROM, such instructions needed to start the computer store. This operation is called bootstrapping. ROM chip is not only used in the computer, but also in other electronic items such as washing machines and microwave ovens.

The following are the various types of the ROM

MROM (masked ROM)

First ROM is hardwired contains program set of data or instructions means. These types of masked ROM is referred to as the ROM they are inexpensive.

PROM (Programmable Read Only Memory)

PROM is read-only memory can only be modified once the user. Users buy a blank and enter with the required PROM PROM programming content. PROM chip inside which opened a small fuse was burned when programming. It can be programmed only once, rather than erased

EPROM (Erasable and Programmable Read Only Memory)

The EPROM can be obtained by exposing it to ultraviolet light for up to 40 minutes duration is erased. Typically, an EPROM eraser implement this feature. During programming, charges are trapped in the insulated gate region. The charge holding more than ten years, because there is no charge leakage paths. Erase the charge, UV through a quartz window (cover). The exposure to ultraviolet light to dissipate the charge. In normal use quartz lid sealed with stickers.

EEPROM (Electrically Erasable and Programmable Read Only Memory)

The EEPROM programming and erasing electricity. It can be erased and reprogrammed about 10,000 times. Both the erase and programming, about 4 to 10ms (milliseconds). In the EEPROM, any position can be selectively erased and programmed. A byte erasable EEPROM time, rather than erase the entire chip. Thus, the process of reprogramming is flexible, but slower.
