The use of computer technology in business provides many facilities. Businessmen are using computers to interact with their customers anywhere in the world. Many business tasks are performed more quickly and efficiently. Computers also help them to reduce the overall cost of their business. Computer can be used in business in the following ways.
These components need to be kept within a specified temperature range to prevent overheating, instability, malfunction and damage leading to a shortened component lifespan.
A computer's microprocessor is usually busy with other work, so the graphics card handles this. The card has a chip called a graphics processor unit, a microprocessor specialized for video calculations. The gpu lets the computer's main processor do its job, allowing the computer to run at full speed.
A processor is the logic circuitry that responds to and processes the basic instructions that drive a computer. The four primary functions of a processor are fetch, decode, execute and write back.
Rom is an acronym for read-only memory. It refers to computer memory chips containing permanent or semi-permanent data. Unlike ram, rom is non-volatile; even after you turn off your computer, the contents of rom will remain.
The hardware are the parts of computer itself including the central processing unit (cpu) and related microchips and micro-circuitry, keyboards, monitors, case and drives (floppy, hard, cd, dvd, optical, tape, etc...).
Contains a very limited amount of data. It is typically just an identifier on a database of that particular product. In the case of upc codes there is a standardized database so your code is assigned to you for each product. In 2d and larger barcodes you can pretty much put in whatever information you like.
Monitors - This Visual Display Unit (VDU) shows information on the screen when you type. This is called outputting information. When the computer needs more information it will display a message on the screen, usually through a dialog box. Monitors come in many types and sizes from the simple monochrome (one colour) screen to full colour screen
A floppy disk is a type of data storage that is composed of a disk of thin, flexible(â??floppyâ?�) magnetic storage medium encased in a square or rectangular plastic shell. Floppy disks are read and written by a floppy disk drive. Floppy disks are a dying and being replaced by the optical and flash drives. Many new computers do not come with floppy drives anymore but there are a lot of older ones with floppy drives lying around. While floppy disks are very cheap the amount of storage on them compared to the amount of storage for the price of flash drives makes floppy disks unreasonable to use.
Random Access Memory or RAM is the memory that the computer uses to temporarily store the information as it is being processed. The more information being processed the more RAM the computer needs.
Computers are used to control large and small machines which in the past were controlled by humans. They are also in homes, where they are used for things such as listening to music, reading the news, and writing. Modern computers are electronic computer hardware.
Computers have made our life easier. With greater precision and accuracy and less time taking computers can do alot in short time while that task can take a lot of time while doing manually.
Computers have taken industries and businesses to a whole new level. They are used at Home for work and entertainment purposes, at Office, In hospitals, in government organizations. Here we are going to discuss some of the uses of computers in various fields.
Computer can be used to manage Home Budget. You can easily calculate your expenses and income. You can list all expenses in one column and income in another column. Then you can apply any calculation on these columns to plan your home budget. There are also specialize software that can manage your income and expenses and generate some cool reports.
An important use of computers at home is playing games. Different types of games are available. These games are a source of entertainment and recreation. Many games are available that are specially developed to improve your mental capability and thinking power.
Random access memory (RAM) is fast-access memory that is cleared when the computer is power-down. RAM attaches directly to the motherboard, and is used to store programs that are currently running. RAM is a set of integrated circuits that allow the stored data to be accessed in any order (why it is called random). There are many different types of RAM. Distinctions between these different types include: writable vs. read-only, static vs. dynamic, volatile vs. non-volatile, etc.
The motherboard is the body or mainframe of the computer, through which all other components interface. It is the central circuit board making up a complex electronic system. A motherboard provides the electrical connections by which the other components of the system communicate. The mother board includes many components such as: central processing unit (CPU), random access memory (RAM), firmware, and internal and external buses.

Scanners- scanners allow you to transfer pictures and photographs to your computer. A scanner 'scans' the image from the top to the bottom, one line at a time and transfers it to the computer as a series of bits or a bitmap. You can then take that image and use it in a paint program, send it out as a fax or print it.
