How are computers different from the past and now?

Answer 1

Computers have changed tremendously over the past 30 years. What once filled a room is now found in the cheapest of feature-phones. What once took a roomful of Accountants to complete can be calculated quickly and easily using standard software. Computers used to have many switches, codes, and commands that needed to be entered by the operator, who was often the programmer as well. Now, it is all simply clicked on, necessitating few decisions, just clicks. Computers have changed in many, many ways.

The years have seen the discovery of new technologies and higher precision manufacturing, allowing us to make smaller devices far more powerful. Consider that the typical phone is as powerful (if not more so) than the typical home computer from the early 90s.

Also, it's worth taking into account the current trends, since today is tomorrow's yesterday - history is made every second. According to the current pace at which we are advancing, by 2020, high-end smart-phones will be able to play many of the games and perform many of the tasks that we, today, associate with our home computers or consoles.

Answer 2

Computers before had the same knowledge of present day calculators (or less) and were often the size of a large room. Now computers are smaller, easier to use, hold more memory, can do more advanced and complex computations, much much faster and so on!

The 1957 printing of Webster's New World Dictionary defines:

computer: see calculator

calculator:

1. a person who calculates.

2. a book of tables for calculating.

3. a calculating machine.

Also, computers are smarter and faster these days. A few years ago it took a few days to download something but now it takes a few minutes. Also, if your downloading something you can still do other tasks on the computer because of more RAM. And computers are much more secure now too.

Most computers have better graphics and design because of modern technology. Computers change year by year.

Answer 3

they mave become smaller, faster, and much more powerful. It would take a computer the size of a house to do half of what your desktop model can do today.

Answer 4

There are more upgrades of course before there wasn't even the internet. But know we have the internet.We also have faster computers.

Answer 5

Cheaper, more powerful, Less generic, more widespread.

Answer 6

smaller faster smarter brighter process-better more ways than you can imagine.

Answer 7

• they used to be large and bigger
• they didn't haded many information

Answer 8

Smaller, faster, lighter, MUCH more computing power, less expensive.
