2. COMPUTER ARCHITECTURE
• Computer architecture is the organization of the component making
up a computer system and semantics or meaning of the operations
that guides its functions,
• Different computer architecture configuration have been developed
to speed up the movement of data allowing increasing processing .
• The basic architecture have CPU at the core of with main memory and
input/output system on the either side of the computer .

3. FIRST COMPUTING DEVICE
• The first counting device was used by primitive people people they
used sticks and bones as a counting tools .As human mind and
technology improved with time more computing device were
developed . some of the popular device early device are described
below

4. ABACUS MACHINE
• An abacus is manual aids for calculating which consists of beads that
can be moved up and down on a series of sticks or string within a
wooden frame . Abacus its self does not calculate ; its merely a device
for helping a human being calculate by remembering what has been
calculate . It said that chines invented abacus on 3000BC.Abacus is
stills used in some countries like china , Russian and Japan

6. DIFFERENCE ENGINE
• In the early 1820s it was desigened by charles Babbage who is known as a
father of morden computer . It was a mechanical computer which could
perform simple calculations. It was steam driven calculating machine
designed to solve tables’ number like logarithimic table

8. ANALYTICAL ENGINE
• This calculating machine was also developed by Charles Babbage in
1830. it was a mechanical computer that used punch – card inputs . It
was capable of solving any mathematical problem and storing
information as a permanent memory

10. ELECTRICAL NUMERICAL INTERGRATOR AND COMPUTER
• ENIAC Was the first programmable , electronic , general purpose
digital computer made in 1945. It was turning computer and able to
solve “ a large class of numerical problems “ through
