Lecture 1 1- What is a computer? 2- What is the Basic computer parts? 3- Define the Desktop computer? 4- What is the Internet? 5- How can we working with Files? Lecture 2 1- A computer system primarily comprises a central processing unit (CPU), memory, input/output devices and storage devices. 2- A computer system comes in various forms and sizes: It can vary from a high-end server to personal desktop, laptop, tablet computer, or a smartphone 3- CPU is the electronic circuitry of a computer that carries out the actual processing and usually referred as the brain of the computer 4- How CPU work CPU is given instructions and data through programs. The CPU then fetches the program and data from the memory and performs arithmetic and logic operations as per the given instructions and stores the result back to memory. 5- While processing, the CPU stores the data as well as instructions in its local memory called registers. 6- CU controls sequential instruction execution 7- How can input Device work? 8- How can output Device work? 9- Explain by year only the Evolution of the Computer system 10- A 4-bit word is called a Nibble 11- A 8-bit word is called a word 12- Kilo Bytes = 1024 Bytes Mega Bytes = 1024 KB Giga Bytes = 1024 MB Tera Bytes = 1024 GB 13- It is of two types of primary memory: (i) Random Access Memory (RAM) and (ii) Read Only
