Computer Hardware

The computer is a great invention that is used in every field including corporate offices and private homes. Computers have made our day to day tasks easier to do and made a great impact in our society that is still evolving and changing each day. Workers are able to do their jobs more efficiently and allow interconnectivity between computer users all around the world through the Internet.

Hard Disc Drive: a HDD is like a person's long term memory. it is used to store any type of data from files to applications. The data on a HDD is non-volatile, which means the data will stay on the disc even if the computer is switched off. A SSD is another way to store data, but it is faster than a HDD because there are no moving parts.

The fastest type of storage is the CPU memory and it is located in the CPU. It runs about 1 ns per access.

There have been many advances since the initial invention of the computer fifty years ago. Today, computers operate many of the things that we use in everyday life. Some examples of these things are farm machinery, cars, planes, video games, heat and water delivery to our homes, banking, billing, and even the stock market. The advances of the computer have resulted in the

Flash memory is a solid-state drive (SSD) that maintains data storage without moving parts, even

A hard disk drive (often shortened as disc, hard drive, or HDD) is a nonvolatile storage device that stores digitally encoded information on fast rotating rigid (i.e. hard) platters with magnetic surfaces. to be precise, “drive” refers to the motorized mechanical side that 's distinct from its medium, like a tape drive and its tape, or a diskette drive and its diskette. Early HDDs had removable media; but, a HDD nowadays is usually a sealed unit (except for a filtered vent hole to equalize air pressure) with fixed media.

The main purpose of storing any information is for easy retrieval in the future when it is required. It is also part of a company’s business practice. Storing documents have to be done in proper procedure so that it is easier to find. Depending on the type of information, information can be stored in either fireproof cabinets for hard copies or hard disks or other electronic storage devices for soft copies.

The hard disk drive can retain the stored information even when not powered. Hard disks are used as storage devices for all type of computer files. Since hard disk drives can be used as an internal disk drive or an external disk drive, they can be appropriately used to most any situations to store important computer files.

I. Computer 's are an integral part of our daily lives. Just about anywhere you go, a computer is present. Hospitals, banks, even the gas pump you frequent, relies on computer 's to figure out how much gas you pump, how much it is per gallon, and where to get that money from. As you can see from this line graph, computer 's are in more demand than ever peaking at 350 million sold in a year. (Computer Sales Statistics)

There are many arguments for and against any type of medium that can be implemented to store and manage data and records. Each medium has its positive characteristics and its drawbacks. The best record keepers use more than one method to store data, mainly as a backup in case of a catastrophe. This is where the old adage, "it's better to be safe than sorry" takes on a greater significance.

19. In __________ file organization, which is the way files are organized on tape, data records must be retrieved in the same physical sequence in which they are stored.

Hard Drive: A Hard Drive is a data storage device used for storing and retrieving data from the drive. It is also a permanent device. Hard drive is considered as internal storage. Hard drive is electromagnetic device.

Hard drive – A hard drive is a non-volatile memory device used to store data permanently and retrieve the same. A hard drive can store different types of data including text, graphics, audio, video, etc. A hard drive works by using platters on which data is written with the help of a magnetic head. The platters and head are encased in an air-sealed case. Hard disks used inside computers are called internal hard disks and are located in a drive bay; they use ATA, SATA, or SCSI cables to connect to the motherboard. They derive power from the PSU (Power Supply Unit).

4. Random Access Memory or RAM. The more ram your computer has, the easier it will be to channel information and processes quickly. Most people won’t notice a huge difference in performance of their computer as long as they have enough RAM.

Storage is how much space your computer will have for your files. The more storage a computer has, the more files and bigger sizes it can hold. There are two types of storage: hard disks and solid-state drives. Typically, SSDs are faster yet more expensive in comparison to hard disks which are much older.
