Whats is a computer? A computer is an electronic device that manipulates information, or data . It has the ability to store, retrieve, and process data. You may already know that you can use a computer to type documents, send email, play games, and browse the Web.

Computer architecture Block diagram of a basic computer with uniprocessor CPU. Black lines indicate data flow, whereas red lines indicate control flow. Arrows indicate the direction of flow. In computer engineering , computer architecture is a description of the structure of a computer system made from component parts. It can sometimes be a high-level description that ignores details of the implementation. At a more detailed level, the description may include the instruction set architecture design, microarchitecture design, logic design , and implementation . [3] History The first documented computer architecture was in the correspondence between Charles Babbage and Ada Lovelace , describing the analytical engine . When building the computer Z1 in 1936, Konrad Zuse described in two patent applications for his future projects that machine instructions could be stored in the same storage used for data, i.e., the stored-program conc
Computer Register Computer registers are high-speed memory storing units. It is an element of the computer processor. Ot can carry any type of information including a bit swquence or single data. A register should be 32 bits in length for a 32-bit instruction computer. Registers can be numbered relies upon the processor design and language rules. The instructions in a computer are saved in memory locations and implemented one agter another at a time. The function of the control unit is to fetch the instructions from the memory and implement it. The control does the similar for all the instructions in the memoru in sequential order. A counter is needed to maintain a path os the next instruction to be implemented and evaluate its address. The figure shows the registers with their memories. The memory addresses are saved in multipe registers. These requirements certainly state the use for registers inscomputer.
