Processor: A computer processer, otherwise known as the CPU (Central Processing Unit) is a part of the computer that receives input and decides that the output will be. Many modern CPUs are capable of processing trillions of calculations per second. The speed of a processor measured by how many operations a CPU can do in one second; this is done in MHz or GHz (Megahertz or Gigahertz). A processer with the speed of 1 MHz does 1,000,000 operations per second, and a 1GHz processer does 1,000,000,000 operations per second. This is known as the clock speed.

RAM (Random Accesses Memory): RAM is used by CPU when a computer is running to store the information that it needs to be used very quickly but it does not store any information permanently.

What do CPU’s do? The CPU is the Central Processing Unit; its aim is to be there the act as the brain of the computer. Other common name for the CPU is the processor. It is in control of the power the computer is receiving and using and the calculations that enable to the computer to be used. CPUs come in differing form factors and each has a particular way in which it will fit on to the motherboard. The most common manufactures of this part that people will know are Intel and AMD. The CPU is in charge of allowing programmes to be used. The CPU sorts the commands of a program into an order which enables it to be used.

A CPU, is what is regularly alluded to as a processor. A processor contains numerous discrete parts inside it, for example, one or more memory reserves for directions and information, guideline decoders, and different sorts of execution units for performing number juggling or legitimate operations.

CPU stands for Central Processing Unit and it’s the brain of the computer. CPU executes instructions that enable the operating system and application software to run on a system. Inside the CPU we can find three main components which are the ALU, Control Unit and memory unit. ALU stands for Arithmetic and Logic Unit and performs calculations like addition, multiplication, division and subtraction. It also compares results using “greater than”, “less than” or “equal to”. Control Unit controls the operation of the memory unit, processor and input/output units. Memory unit is where all data that the CPU may need to process is stored. The data is stored in the memory in binary form.

This section gives the details and specification of the hardware on which the system is expected to work.

The program by its self is just instructions writing in code where a process is an active program which has been executed. The CPU executes one instruction at a time until the process completes.

The CPU is housed in the motherboard is considered the heart of the computer, it controls everything. CPU stands for central processing unit; it is one of the main components of a computer. The CPU or more commonly known as the processor is electronic circuitry which follows the instructions of the hardware and software on the computer, it effectively is a very efficient calculator carrying out arithmetic, logical, control and input/output operations.

The five major components of an information system are as follows (1) to (5); (1) Hardware, multiple computer systems: microcomputers, minicomputers, and mainframes. (2) Software- computer software falls into two categories; systems software and applications software. Systems software manages the resources of the computer system and simplifies programming. Application Software is a program that directly assists end users in doing their work. Both can be purchased as ready-to-use packages. (3) Networks and communication facilities, includes Internet and intranets. This hardware and software facilitates fast and efficient transmission and reception of text, pictures and

A core is usually the basic computation unit of the CPU - it can run a single program context (or multiple ones if it supports hardware threads such as hyperthreading on Intel CPUs), maintaining the correct program state, registers, and correct execution order, and performing the operations through ALUs.

Computer- A computer the process-recieves in, thinks about, changes, stores, sends out, displays, and prints data in the form of bits.

System Analysis is the study where detailed information about the components and requirements of a system, the information needs of an organisation, the characteristics and current components of the systems and the user functional requirements of the systems that is proposed system.

A computer is an electronic device that stores, retrieves, and processes data, and can be programmed with instructions. A computer is composed of hardware and software, and can exist in a variety of sizes and configurations. Hardware is the physical equipment of a computer system, including the central processing unit (CPU), data-storage devices, terminals, printer, etc. Software is a program or set of instructions or rules that control the operation of a computer.

Computer system plays an important role in solving human problem in their daily life. There are standard steps in order to develop information system called System Development Life Cycle (SDLC). SDLC is the framework available to build a complete system. There are five phases in SDLC which are planning, analysis, design, coding, testing and maintenance (refer to Figure 1 in Appendix 1).
