- Storage
The computer can work very fast. It takes only a few seconds for calculations that we take hours to complete. A computer can perform millions (1,000,000) of instructions and even more per second.
Speed
The degree of accuracy of a computer is very high and every calculation is performed with the same accuracy
Accuracy
A computer is free from tiredness, lack of concentration, fatigue, etc. It can work for hours without creating any errors
Diligence
It means the capacity to perform completely different types of work. You may use your computer to prepare payroll slips.
Versatility
A computer has the power of storing any amount of information or data. Any information can be stored and recalled as long as you require it, for any number of years
Power of Remembering
A computer is a dumb machine and it cannot do any work without instruction from the user. It performs the instructions at tremendous speed and with accuracy. It is you to decide what you want to do and in what sequence. So a computer cannot take its own decision as you can
No IQ (Intelligence Quitient)
It does not have feelings or emotions, taste, knowledge, or experience. Thus it does not get tired even after long hours of work. It does not distinguish between users.
No Feelings
The Computer has an in-built memory where it can store a large amount of data. You can also store data in secondary storage devices.
Storage
is the use of any computers, storage, networking, and other
physical devices, infrastructure, and processes to create,
process, store, secure, and exchange all forms of electronic data
Information Technology (IT)
IT includes several layers of physical equipment
Hardware
virtualization and management or automation tools, operating systems, and applications used to perform essential functions
Software

- Protecting and Storing Information
- Automated Processes
- Communication
- Remote Access or Telecommuting
- Electronic storage systems are being
created to hold the information that is being shared over the internet and internal intranets. Secure maintenance of customer and company files is vital to the integrity of the company
Protecting and storing information
The ability to find ways to complete more work in a
shorter amount of time is essential to the success of a company
Automated Processes
in every aspect of human interaction is
essential.
Communication
When a company has implemented an
information technology system, many times employees can then access the company’s network electronically. This enables employees to work from home or while on the road. This gives the employees more flexibility and they are more productive because they can still work when not in the office.
Remote Access or Telecommuting
Setup costs for implementing an information technology system within a home or business can be very costly. Software training can also take another big bite out of the budget.
Expenses of Implementation and Maintenance

- Expenses of Implementation and Maintenance
- Elimination of Jobs
By implementing IT systems into a company, tasks take less time, and therefore, employees have more time throughout the day. Paperwork is processed and filed immediately, reports are generated with the touch of a button, and financial statements are generated automatically. Companies are finding that they can combine jobs and need a smaller staff to operate fully.
Elimination of Jobs
is the technology required for information processing, in particular, the use of electronic computers, communication devices, and software
applications to convert, store, protect, process, transmit and retrieve information from anywhere, anytime.
ICT (Information Communication Technology)
refers to the knowledge obtained from reading, investigation, study, or research.
Information
is an act of transmitting messages. It is a process whereby
information is exchanged between individuals using symbols, signs, or verbal
interactions.
