first personal computer had less features than today's personal computers.
Today we use personal computer with high speed and more storage space.
The first personal computers were so heavy they had a big carrying handle.
Power! That would be the biggest difference. Availability, cost, space required to put a computer. Some of the old ones took up the space of an average basement and more. Another difference would be smarts. A lot of today's computers can think on their own. There is one super computer that runs an entire aquarium, if I remember correctly it is the second or third largest in the US. This computer will talk to you, answer questions like, 'What is the status of tank 12 and the status of filtration system 14?' Or 'How much oxygen is in tank 15?'. It will answer questions like that. Not only that if there is a big problem, it will page someone on it own. It can also handle smaller things itself like maintaining a constant temperature, oxygen level and the like.
If you have seen a photo of the ENIAC, one of the first computers (from the late 1940s), you will notice it is huge, compared to computers from today. Early computers were almost the size of a room, and they used a lot of energy, and a lot of vacuum tubes. Today, of course, computers use microprocessors instead of tubes, and are much smaller (we have laptops, desktops, notebooks, etc).
In addition to their larger size and their use of vacuum tubes, the early computer was more like a calculator. Today's computers can perform complicated operations, from translating foreign languages to providing answers to questions at lightning speed, and they can access the entire world-wide web. In the late 1940s, there was no internet, and the ENIAC was praised for its ability to perform mathematical procedures (adding, subtracting, multiplying, dividing) very quickly.
computers today are the best today we can even buy are socks online. Before the computer were bigger and they use to only add simple math only and they use to also have water for it to work.
Their computers are huge. Ours would smash theirs technology.
speed,memory capacity,performence
Yes.
difference Engine
No. The first computer that resembles modern computers was made in the early to mid 40s. They were considerably larger and less capable than today's computers, but they were computers none the less. Apple released their first computer kit - the Apple I Personal Computer Kit in 1976.
There are many difference between today and 150 years ago. We now have cars, computers, and the Internet among numerous other changes. The roles between men and women are even different today.
The main difference between first generation and fifth generation computers is upgrades. Typically, first generation is more of a beta system and fifth has had many upgrades added to it to make it run faster and has a better performance.
the first computer was slow and huge and dependable, but our computers today are faster, smaller, and very dependable
Yes.
A single man never invented a computer.Computers were developed in stages,from simple Abacus to the Computers we know today. First came the Abacus and Pascal's bones.Then with introduction of Analytic and and Difference engine and further introduction of Nano tech. made things easy and lead to the computers we know today.
difference Engine
It means that today's have come a long way from the very first made computers which were probably a little over a forth the size of your room.
How Are Computers Used Today?

With today's technology, Humans have more insight than computers and life appears to be more vivid than the computer's. But that may change someday (It will).

Early Computers were large in size while today computers are compacted .Early Computers were Vaccum tube and transistor based while today computers are ICs based.Early Computers were slow and today computers are fast.Early Computers were used punch card for storage while today computers used Secondry storage ( Hard Disk) for storage.Early Computers were not user friendly todays computers are user friendly
