Difference Between: The 5 major difference between RAM & ROM in Computer with definition ,full form of RAM and ROM with its uses in Computer & also brief explain RAM and ROM with example

  What is RAM? Definition Of  RAM.

Random Access Memory (RAM) is a computing device in which the data is kept in the operating system (OS), application program and current usage so that it can be accessed quickly through the device processor. RAM is the main memory in a computer, and it is very fast to read and write with other types of storage such as hard disk drive (HDD), solid-state drive (SSD) or optical drive.

Random access memory is unstable. This means that the data is retained in the RAM as long as the computer is running, but it is lost when the computer is switched off. When the computer is rebooted, the OS and other files are usually reloaded from RAM with HDD or SSD.

A computer also works like this. If RAM is filled up, then the computer processor should go to the hard disk repeatedly to overlay the old data in the RAM with the new data. This process slows down the operation of the computer.

Categorized Under: Hardware Device |Technology | Difference Between Computer And Laptop

What is Computer/desktop: Simple Definition of Computer

A computer is a machine capable of taking input and processes it to create new information (output).

The calculation of machines is old in the history of technology. The initial examples are Astrolabe and abacus. Today, a computer is a programmable machine. The computer has two main characteristics: it responds to a specific instruction set in a well-defined manner and it can execute a preceding list (a program) of instructions. There are four main processing steps in the computer: input, storage, output, and processing.

The main point of the computer :

• The word Computer is Obtained from the Latin Word " Compute" which means "to calculate or "to "count".
• Just Like Other Machines Make Work Easier.
• Majority of People have referred PC (Personal Computer)  as the Real Computer.
• A computer can also be described as an electronic Machine that saves, transmits and process data into information. 
• For Example: In calculator add the two numbers 5+5=10.in which (5+5) as input and the (10) is Output is Represent on Screen.
• A computer is a Machine that performs four basic operations: input processing, output processing, Storage. these four operations are called the information-cycle.

What is Laptop: Definition of Laptop

A laptop (also called a notebook) is a computer that uses batteries or AC power that can run for several hours. Unlike desktops, laptop computers are easily delivered and can be used as long as the battery runs.

However, it is becoming very common to provide power units for phones and laptops for public places so that they can be used almost everywhere!

Laptops come in different sizes with different specifications. Like the desktop, the type of computer depends on consumer needs.

A laptop has a built-in monitor, keyboard, and usually touchpad (or trackball). Based on the ports provided by the manufacturer, external peripherals can also be added using various cable connections. Essentially, without any connected device or power, the laptop can be used as a fully functional unit.

As the technology progresses, the laptop is becoming more popular with the preferred computer for the average consumer and business users, especially those who travel for work.

Similarities between Computer and Laptop 

Most desktops and laptops are sold with pre-installed software and operating systems such as Windows 7, or if it is an Apple Computer, then Mac OS.

Both computer units come with port connections (separate between each make and model) and embedded CD / DVD component, however, some of these step-by-step steps are the latest laptops.

Peripheral external hard drives, printers, cameras, and phones etc. can be connected to devices.

For desktops and laptops, there are important specifications to consider before purchase.

Cpu

Memory (RAM)

Hard Drive Capacity

The Main difference between desktops and laptops

The biggest and most noticeable difference is that the desktop requires basic external devices to be fully functional, while laptops have all the necessary devices, which make it the most portable.

Mobility

The desktop office or home is in place and requires a computer terminal to connect to the external monitor, keyboard, and mouse; While laptops have built-in components and thus are easily transported as a full device which can be used in most environments.

Power

The laptop can run AC power, battery, or main power, while the desktop can only run the main powers. It is not manufactured for any battery usage.

Over time, the laptop battery has improved and depending on how much processing power is being used and the opening of WiFi or Bluetooth connection, the consumption of batteries increases depending on how long it can run for several hours.

Speed

While desktops and laptops are becoming more equal in terms of speed and performance specifications, the desktop still remains as a more powerful alternative to activities like gaming and video production.

Buying the same glasses of gaming laptops on the gaming desktop will be at a much higher cost than the gaming desktop.

If a computer is required to view original office processing, internet usage, and photos, then a standard laptop will be perfectly suitable.

Specifications

Generally, laptops are known for fewer spectacles than desktop, because there is a compromise on size and portability, versus performance and speed.

Screen size:

Desktop monitors can be up to 34 inches wide by 15 inches screen. Laptops have built-in screens that have different sizes.

The bigger the screen, the bigger the laptop, the larger it will be, however, if a small laptop is bought for easy mobility, then it can be connected to a larger external monitor if possible.

If connecting an external monitor on an external computer that permanently resides in one place, the size of the monitor will not be a restrictive factor as it is set up once and is not necessarily transferred, hence weight is an issue Not there.

Storage, Memory, and Data:

To store large amounts of data, desktop computers will be a better option and if necessary, additional memory can be added to improve performance, or hard drives can be replaced. Laptops cannot be expanded as easily as the desktop.

Backup is recommended for all data, even if it stays on a desktop or laptop, even if using a laptop causes the risk of data moving with mobility due to theft, loss of computer, physical damage (drop Leaving) computers, etc.

Performance	Desktop processors have always made more powerful than laptops with big processors.	Laptop processors are catching on the desktop but they still have size limits to fit with portability.
Ease-of-use-assembly	By avoiding cable chaos, the desktop needs to be manually set up by adding necessary tools and they require larger workspaces than laptops.	The laptop should be operated and opened just before it is ready for use. There is no effort for basic setup.
cost	Access-level desktops are relatively economical for most consumers. There is a large variety of peripheral devices.	Access-level laptops have a higher starting price than the desktop. The higher the specs, the more cost that can increase significantly for the laptop model.
Monitor and keyboard	There is no limit to the size and weight of external equipment because the desktop is not for portability.	The size of the screen and keyboard determines the size and weight of the laptop, which is considered for portability because it should be considered.
Upgrading	Within the desktop computer the component can be removed and replaced and in most cases easy upgrades of storage capacity, memory, graphics controller etc. are allowed.	In laptops, only hard drives and memory can be replaced, but other cards and components cannot be removed. To upgrade any other aspect, you will need to buy a new laptop.
Maintenance and Repairing	It is very easy to fix components in desktop computers because it allows the removal and replacement of many parts available from most computer hardware stores.	Due to the removal of most components in compact designs and laptops, it requires repair of technical expertise.
Gaming	Gaming is considered more powerful for gaming because graphics and video cards can be on top because there is no limit on power consumption and more than one video card can be installed.	Laptops are limited to space, so the size of some components is limited. Gaming laptops are above average glasses but they are still limited to space to keep portable. The power consumption on an unplugged Laptop will increase drastically with gaming activities.

 Key demerits and disadvantage of computer 

The following are the disadvantage of computer

Health issues

When the PC is used for a long time, the radiation emitted by the monitor has a negative effect on the eyes. Eyes are dry, resulting in blurred vision, tension in the muscles of the eye, weak eyes. While using the computer for a long time, some careful measures should be taken, taking a small break while using, making the eyes wet with water, the eyes can help a lot easier.

When the continuous use of previous muscles becomes difficult due to improper sitting positions, their elasticity in the neck muscles, pain in hands and joints are the primary adverse symptoms of the use of computers. The negative consequences of doing more work with the computer can be overcome by coming or resting between tasks. Inappropriate digestion is also available to those who work on PC for the long and continuous period.

The spread of pornography

Since the range of PCs has covered every single person in the society, children and even grown up and are involved in pornographic content that presents many websites this day. Such content, videos, and images are readily available on the Internet, people can reach easily, it is very difficult to control, a large number of children are addicted to porn videos, porn images, and once they are accustomed It is difficult to get away.

Many social organizations and even the government find it very difficult to overcome. And to prevent the spread of obscene content, it is a major and significant loss of computer usage. It has been a universal issue for many years.

Virus and hacking attacks

Viruses are computer programs that are designed and developed to harm the computer, steal important information such as passwords, pins, and other sensitive information. Hackers use this system to crack their systems and gain unauthorized access to their computer systems, which can harm people financially.

While surfing the net or using online software, legal software, antivirus programs, and anti-hacking software should be used to reduce hacking and virus attacks. Data protection is a major concern due to computer viruses and hacking attacks. Many companies provide services for data protection.

The computer can not make its own decision

Since the PC does not have its own intelligence, so they can not make decisions on themselves, which sometimes make our work tedious, it seems that when they get wrong or inappropriate instructions from the computer, then they do the right thing If you do, then the result will be wrong. The logical mind is not set right or wrong.

Negative impact on the environment

Computer waste and manufacturing process produce a lot of waste. Which is harmful to the environment and to our society. Used computers or computers which are no longer in use should be donated. There is the production of wastewater harmful chemicals which pollute our environment and nature, so green computers should be used as it has no adverse effect on the environment and can be recycled.

Crash network

Computers can be easily connected to each other through "networking", it can connect to the internet. Imagine that you have 25 computer's offices, all computers are connected to each other with internet connected. During this time all your employees work differently on their respective computers and one day your network goes down or the whole network crashes. You will find that all the computers that are connected to each other stop working and hence no production or no work. This is often a significant loss to computers when used in the network.

Violence and hatred spread

While surfing the Internet, the dissemination of articles related to violence and hate can be easily found. People come in contact with this article which destroys the thinking process of individuals and we get results that are not for the improvement of human society.

Cyber crimes

Some people who are usually called "hackers or crackers" break our computer systems and gain unauthorized access and steal our password and our sensitive information on our credit card numbers. With this information, they violate all laws and abuse our information about their benefits.

Data and infringement violations

Despite many securities, our data may be lost due to damaged memory or while using inappropriate program trojan by using spam websites, the worm on your computer system corrupts or destroys the data available on your system.
