How did second-generation computers differ from first-generation computers?
151802
First generation computers are remarkably slower and have less memory and less advanced software.  Second generation, however, is todays generation which is an improvement over the previous generation.

do a yahoo or google search on the subject because it depends on who manufactured the pc,mobo,etc.

Both XP and 2003 are based on NT technology. If XP is dedicated primarly to pc's, so a general use public, 2003 focuses on servers and mainframes! This is the main difference between them. \nFor example XP doesn't support multiple processors, while 2003 does. Xp supports maxim 4 Gb of RAM, while 2003 supports up to 16 Gb of RAM. The security issues are more advanced in 2003, since it's ment for servers as already mentioned.

I repaired computers for 20 years, including first generation machines that weighed tons.  I can't even remember how much training I have had in theory but I simply don't recognize "series" as anything I ever worked with.  If it is related to programming I couldn't help you but if it is hardware related maybe some additional information might help.  I will place this on my watch list and check it later.

hey\n this will help\nSupercomputer\n        Supercomputers are the fastest types of computers. Supercomputers are very expensive and are employed for specialized applications that require immense amounts of mathematical calculations. For example, weather forecasting requires a supercomputer. Other uses of supercomputers include animated graphics, fluid dynamic calculations, nuclear energy research, and petroleum exploration.\n\nThe chief difference between a supercomputer and a mainframe is that a supercomputer channels all its power into executing a few programs as fast as possible, whereas a mainframe uses its power to execute many programs concurrently.\n   \n   Mainframe\n        A very large and expensive computer capable of supporting hundreds, or even thousands, of users simultaneously. In the hierarchy that starts with a simple microprocessor (in watches, for example) at the bottom and moves to supercomputers at the top, mainframes are just below supercomputers. In some ways, mainframes are more powerful than supercomputers because they support more simultaneous programs. But supercomputers can execute a single program faster than a mainframe. The distinction between small mainframes and minicomputers is vague, depending really on how the manufacturer wants to market its machines.\n   \n   Minicomputer\n        A midsize computer. In size and power, minicomputers lie between workstations and mainframes. In the past decade, the distinction between large minicomputers and small mainframes has blurred, however, as has the distinction between small minicomputers and workstations. But in general, a minicomputer is a multiprocessing system capable of supporting from 4 to about 200 users simultaneously.\n \nand try following link

I've never heard of either of these.  There was an Atari 1040ST, a 16-bit computer.  It was based on the Motorola 68000 CPU, and was a contemporary of the Commodore Amiga and the first Apple Macintoshes.

There is no such thing as newer computers - as you buy a "new pc" a different higher spec is on the market, e.g. CPU speed and RAM

It all depends. If they were asking you to explain what a computer is in 1900 it is not possible since I don;t think computers were available back then. If they are asking to explain present technology to someone from the 1900, I would start out with te basics of the different componets of a computer, eg. hard drive, mother board, power supply, RAM, disk drives, and etc. The reson for this is that you need to understand how a computer works before you can even get to software.

NO! they are different.\nthe motherborad is more like a 'circuit holder'\nhowever the processor, which is fitted into the motherboard, is the 'brain' of the computer. It takes care of all teh timing requirement, memory management, and various other operations crucial to the working of the comp.

The word COMPUTER  has been derived from the word COMPUTE which means to Calculates, Analyses, Interprets or Compuites and etc etc .... Because the machine literaly calculates using numbers (generally 1 and 0) So, you can guess there is no difference between a CALCULATOR & a COMPUTER.  In the begining of the computer era, they were called "Computing Machines". \nSo, any machine which computes is called a COMPUTER.

cache is memory, just like any other memory on your computer.\nThe difference between RAM ( random access memory) and cache\nmemory, is the location and speed, and how it is used.\n\nIt was discovered that by PREDICTING what memory locations\n" Were GOING to be used ", the computer could speed up the\nthe process of reading the next set of memory locations,\nby having a "predictor" program load the memory into VERY\nfast memory, close to, or inside the CPU ( Central Processing UNIT ie the Pentium chip ). There are different levels of Cache RAM, usually called L1, L2, L3 etc. (Level 1, Level 2etc. ) with\nL1 Cache being built right on the chip itself, or on chips\nbuilt onto the CPU chip module at the factory. L2 Cache ram\nis usually added in slots very close to where the CPU ( Pentium), is located on the motherboard. Believe it or not,\nthe computer chips run so fast, that electricity, moving at the speed of light, takes TIME, to travel across the circuitboard, so that the L1 cache is in the heart of the CPU, and the L2 add on cache is as close as possible to the\ncore to speed up the transfere.\n In early Pentium ( and AMD, Cyrix, IBM, etc. clones,) the\nL1 cache was controlled by what can be considered an entire computer WITHIN the CPU. This "computer" had a program, with\nits own ram, and rom, and it was pre-programmed at the factory. Its job, was to watch what the (big) computer was doing, and predict, what the computer was going to do NEXT. For example, if you were running a program that used program lines 345, 346, 347, 348, then it would predict that you\nwould use lines 349, 350, 351, 352, etc, and load them from the " SLOW" ram cards in the ram slots, into the blazing fast Cache ram, right inside the CPU itself, where the\nCPU could access it immediately. There are different kinds of cache ram within the "Cache" " Predictor" program, such\nas TAG ram, Dirty ram, etc. which are used to keep track of what ram is loaded, used, and changed, by the running software that the CPU is currently using. Tag ram would keep  a list of the ram locations that were loaded into the L1\ncache, and the Dirty ram, would keep track of which L1 cache\nlocations had CHANGES made - when the "predictor" program\ndecided that NEW locations of slow RAM were going to be used, it had to put back the old RAM locations' memory contents. It Could ignore memory values that WERE NOT CHANGED ( saving time otherwise spent writing the information BACK to the slow RAM ), but would have to write\nback any CHANGED ram back to the slow ram (marked dirty).\n AMD invented very clever and powerful "predictor" programs in some of its early chips, and this made such a dramatic difference that it out-performed the much more expensive Pentium chips. The "predictor" computer program component is now extremely important in achiving faster speeds. CPUs typically have 64k ( K is one thousand (( 1024 bits) ), 128 K, 256K, or 512K of cache built in, and many motherboards can have slots near the CPU that the user can add more\nL2 cache ram, for use by the predictor CPU program section.\nCache ram is typically much faster, but much more expensive to construct in the factory, so that chips with more cache are usually a lot more expensive. Since CPU speeds are reaching a limit for the moment, the manufacturers are increasing the L1 CACHE to 1 or more MEGA BYTES, on the high end chips.\n SOOooooo... cache is not "just" fast memory. It is a program, inside the CPU, running constantly to predict what memory is "going" to be used. This program goes out to the slow ram, and grabs the memory contents, and loads it into\nL1 cache BEFORE the computer asks for it, to speed up memory transfere. If the predictor is correct in GUESSING the next memory locations, the entire computer speeds up greatly....\n\nHope this clears up "cache"...

The very first computers were digital.  Kids quickly learned to count to ten (and still do!).  The next generation of computers were analog where for example vertical marks on the wall were analogous to the number of sheep.  We still use vertical marks to gage the amount of gas left in the tank using an anlog computer.  Then came the abacus that was speedier than most table model calculators, even when operated by skilled accountants.  Next came digital computers that filled an entire room and worked using vacuum tubes and electro-mechanical relays.  Once such a computer failed to operate properly and the operator found an insect caught in a relay.  Ever since, many has been trying to debug computers.  Hope that helps a little.

This is actually a fascinating question, so I'm going to give a long answer.  The short answer is "Nothing.  Nothing is similar."  Here's the long asnwer:\n\nTo the average user, it seems like there are a lot of similarities: \n\nthey both have memory, \nthey both take in information and put out information, \nthey both need sources of power\nThey both "think," sort of\n\nBut really, these are only similarities on the surface.  Although both you and your computer have memory, there are vast differences in how memory works, to the point where using the same word for the two types of memory is misleading.  While both you and the computer "think," how you do so is vastly different.  You work in patterns, the computer works in digital representations, which is more precise but far less efficient.\n\nComputers are phenominally fast calculators, but that's all.  They can add, subtract, multiply, divide, and move information around.  And nothing else.  I'm a programmer, trust me on this.  Everything they do is based on those basic operations.  Playing a video game is just basic math done incredibly fast.  Displaying an e-mail is just basic math on memory addresses and moving a block of numbers (representing the letters) from one location to another, where it can be turned into pixels (complicated math, but math none the less) and moving the results to specific memory ports where the electronic adapter turns the numbers into colors on the screen.  Computers seem "smart" because they're wickedly fast at processing numbers.\n\nYou, on the other hand, do poorly at numbers.  (And by 'you', of course, I mean humans.  But you knew that).  The fastest human savants calculate thousands of times slower than the computer in your microwave oven.  \n\nYou have advantages, though.  Your brain is a phenominal pattern matcher.  Your pattern matching abilities exceed anything any computer can achieve.  For example, if I scrawl the word "Howdy there!" on a piece of paper and hand it to you, you'd instantly know what it said, even if I was a wee bit sloppy with the letters or gave it to you upside-down.  The letters (and even the words) are patterns you've seen before and can immediately interpret them.  A computer would have to analyze it pixel-by-pixel and MIGHT be able to interpret the letters eventually.  But in all probability, the computer is going to have trouble figuring out where the lines start and stop, and which line goes with which line in the text.  Character recognition is a tricky thing for a computer... and if you give it the text upside-down it'll never figure it out.  \n\nEven a six-month-old baby is better at recognizing different faces than the best computer program running on the fastest computer that Homeland Security has.  And trust, me, they're working on improving that so they can recognize bad guys from security cameras.  \n\nNow we get back to memory and how vastly different they are.  A week from now, you'll remember that the paper said "howdy there!" and may or may not remember vaguely whether the handwriting was neat or sloppy.  This is because your memory stores the pattern.  The computer, however, could give an exact reproduction.\n\nStudies have been done with what types of things people remember.  When flashed briefly with an image of a cluttered desk, for example, and then asked to write down what was on the desk, people tend to remember the things that are out of place (a shoe, a tennis ball) and not remember things that were expected there (a stapler, a cofee mug).  This is because that powerful pattern matcher in your head evaluates the pattern (an office desk) and notes anything that doesn't match.  Your memory doesn't need to store typical desk items as much as it does exceptions.  It's very efficient that way.  You filter out the "ordinary" and spend almost no time thinking about the

There are three main types of computers, first off:\n1. Server\n     a. Rack-mountable (small)\n     b. Tower-style (big)\n2. Desktop\n     Desktops are commonly classified according to motherboard form factors: BTX, ATX, MiniATX, MicroATX, Mobile, NLX, etc.\n3. Laptop\n     a. Desktop replacement\n     b. Portable\n     c. Ultra-portable\n\nOf course, this doesn't take into consideration PDA's and Smartphones, or some of Apple's ultra-compact desktops.

None really. Originally "Notebook computer" was used to define a smaller and lighter portable computer but the terms are used pretty well  identically these days.

That depends on what you mean by "computer".  The basis of any computing machine is the ability to do input, processing and output.  The core of what makes it a computer is to handle "whatif" questions and to respond differently based on the answer to those questions.  For example, to say, "If the dollar amount is less than X then do this, but if it's greater than X then do that.\n\nBy that definition, the first true computer would probably be Charles Babbage's "Difference Engine" built in the late 1800s.  An improved version, which he called the "Analytical Engine" actually accepted punch card programs, the first of which was written by Lord Byron's daughter, Ada Lovelace, making her the world's first computer programmer.\n\nThe first truly modern electronic computer was, arguably, the ENIAC developed for the US Army by the University of Pennsylvania.  I say "arguably" because it depends on which features you want to include in the definition of "modern electronic computer."  For example, the ENIAC had no stored memory and had to be rewired for each program.\n\nHope this helps.
