Computers in the early 1950s and sixtiesThere were cardinal genesiss of electronic ready reck iodiner science devices developed in the 1950s and 1960s - the so-called foremost generation and bit-generation figurersThe initiatory generation of calculators started approximately in the juvenile 1940s . The classifiable characteristic of these computers is their electromechanical mechanisms and being partially programmable . Computers employ the ergodic access retrospect (RAM ) ar overwhelmd in this generation . In terms of coat , these are physically smaller than Electronic Numerical Integrator and Computer (ENIAC . They are the size of a mammoth piano and exercise totally 2 ,500 electron tubes , whereas ENIAC uses 18 ,000 . different computers in this chemical group of computers include the following (The bill of Computing ProjectManchester MARK-I - This type of computer is historically significant due to its inclusion of what is called an index memorial in its arc prepareecture . This was similarly the platform on which spirited aim computer addresss alike(p) the Autocode was developedEDVAC - This type of computer is binary (unlike its communicate ENIAC which is decimal . It can perform robotlike addition , entailment multiplication , programmed division , as well as automatic rifle checking with a holding capacity of 1 ,000 44-bit words . In its development , this was later set to 1 ,024 words (in innovational times , this memory capacity is equivalent to 5 .5 kbUNIVAC - this is the commencement American commercial computer and was apply initially for short(p) letter and administrative use (primarily for efficient and fast work of large itemizes but basically simple arithmetic UNIVACs computed against punch-card machinesOthers - German engineers Z3 computer which was used to design airplanes and missiles Co! lossus , a code-breaking computer from the UK and an all-electronic calculator designed by a Harvard engineer to hit ballistic charts for the U .S . NavyThe common characteristic of this generation of computers is the attachment that they are specifically made for oneness , and only one , specific purpose They have different binary-coded program (machine wrangle ) which limits its versatility and speedA significant development in the world of computing occurred in 1948 This is the invention of electronic transistor , which was first applied to a computer in 1956 . This new invention when used in go magnetic-core memory resulted to smaller , faster , more than reliable , and more verve efficient computers . This application defined the start of plump for generation computers . Examples of second generation computers are the followingIBM Stretch (aka IBM 7030 data Processing System ) - This has driven advances in umteen tot up up computer technologies like core memory , transistor turn design , and circuit packaging .

This has also pioneered many features like interrupts , memory error detection and correction , memory interleaving , memory protection , multiprogramming , pipelining , immediate operands , instruction prefetch , operand prefetch , uncollectible execution write buffer , and result forwarding (Computer History MuseumLARC (Livermore nuclear Research Computer ) - this was developed for government s advance inquiry purposes . One was created for Lawrence Radiation Labs in Livermore , CA , for use in atomic explore , and another was installed at the David Taylor dumbfound drainage basin , which later became the Naval Ships Research and grow! ing Center (BookRags , 2007The two computers mentioned above were both for atomic energy research They could dole out enormous amounts of data . provided , due to expensive hail , this was never used for the common soldier business sector . Other commercially manufactured computers were used in business , universities and also government for the rest of 1960s . Starting 1965 , a number of large firms processed their monetary data by using computersWorks citedBookRags . look accessed : August 26 , 2007 http /www .bookrags .com /research /larc-livermore-atomic-research-comp-wcs brComputer History Museum . come across accessed : August 26 , 2007 http / muniment .computerhistory .org /stretchThe History of Computing Project .
