Computer Memory The Brain Of A Computer

Computer Memory- The Brain Of A Computer

In today&25263; digital world, computer is considered to be one of the most essential electronic gadgets bluestacks clash of clans hack of our lives. With the aid of computer, you can easily perform any types of works without any hassle. Moreover, there is an abundance of job positions, which allow people to work from home simply using their personal computer. To work from home, you simply need your computer and an Internet connection. Like human brain, computer can keep all data and files with the aid of computer memory. To store more files and data, a huge storage space is required for a computer.

How can we define computer memory? You already know that the computer in front of you has memory. What you may not know is that most of the electronic items you use everyday have some form of memory also. Computer memory refers to devices that are used to store data or programs on a temporary or permanent basis for use in an electronic digital computer. Computer represents information in binary code, written as sequences of 0s and 1s. Every computer comes with a certain amount of physical memory, usually check here referred to as main memory or RAM. You can think of main memory as an array of boxes, each of which can hold a single byte of information.

Today, capacitors and transistors, functioning as tiny electrical switches, are used for temporary storage, and either disks or tape with a magnetic coating, or plastic discs with patterns of pits are used for long-term storage. Again, computer memory is usually meant to refer to the semiconductor technology that is used to store information in electronic devices. Current primary computer memory makes use of integrated circuits consisting of silicon-based transistors. There are two major types of memory namely volatile and non-volatile.

Volatile memory is a kind of computer memory that requires power to maintain the stored information. Current semiconductor volatile memory more details technology is usually either static RAM (see SRAM) or dynamic RAM (see DRAM).

On other hand, Non-volatile memory is computer memory that can maintain the stored information even when not powered. Examples of non-volatile memory include read-only memory (see ROM), flash memory, most types of magnetic computer storage devices (e.g. hard disks, floppy discs and magnetic tape), optical discs, pen drive etc.

Computer Recycling Switch To Environmental Friendly Mode

Computer Recycling ?Switch To Environmental Friendly Mode

Computer recycling refers to the practice Check our website of salvaging useable components from obsolete electronic devices or safely disposing off electronic devices. It is a practice that each one of us must inculcate because inappropriate handling of discarded computers and other electronic devices can cause environmental hazards.

Studies estimate that over 40 million electronic pieces become obsolete annually. These share this site pieces have constituents such as lead, cadmium, barium, and mercury, which are hazardous to the environment. In a landfill, these materials seep into the ground and then into our food and water supplies. This can cause serious health concerns over a long period.

Obsolete Computers: Environmental Threats
Obsolete computers that are simply dumped in the garbage drums are the biggest threat to the environment. The computer monitors have cathode ray tubes containing four to five pounds of lead that contaminates the environment acutely. Besides lead, the computers have many other hazardous elements such as mercury, cadmium, and hexavalent chromium. When inhaled over a long period, these elements cause high blood pressure, liver and nerve disease, blood with poor iron, and even brain damage to the exposed group. This causes great concern, considering several million computers become obsolete annually.

Therefore, we must handle the obsolete electronic devices carefully. Moreover, different Environmental Laws have banned the illegal landfills by the disposals of computers and other electronic equipment. These laws necessitate sending the un-functional computers to a reputable recycler for harmless recycling. The laws also specify the need for regular recycling to avoid such computers from piling up.

There are several methods to deal with old computers. Some of them are as follows:

?Give It For Reuse: If your computer megapolis cheats hack is in a decent condition, you can sell it to a company or an individual so that it can be used further, or simply donate it to someone needy.

?Trade It In: There are many computer dealers (e.g. HP) who offer trade-in promotions on computers and peripherals.

?Auction It: You can sell the computer on eBay or any other auction site. You can also organize a quick garage sale and see if any of your friends or neighbors wants the computer.

?Set up a Server: You can continue using the old computer as a server to store and share data.

?Salvage Some Parts: You can see which parts of your computers are in good working condition. You can salvage those parts and use them in your new computer.

Go for computer recycling and safe the planet earth!
