Study Notes
Computer Storage and Basics
- The main function of computer storage is to hold data, programs, and the operating system.
- At its most basic level, a computer understands binary digits (bits) that can have a value of 0 or 1.
Binary System and Data Representation
- A nibble contains 4 bits.
- The binary value of a bit is either 0 or 1.
- A byte is the unit of digital information in computing and telecommunications, and it consists of 8 bits.
- The binary system is based on the concept of binary digits (bits) that can have a value of 0 or 1.
Memory and Storage
- Random Access Memory (RAM) is a type of volatile memory.
- An example of a storage device whose media are not directly accessible by the CPU is a tape drive.
Programming Languages
- Language processors are used to convert high-level language into machine code.
- Compiled programs run directly on the computer system.
- An interpreter translates program code to machine level language on a line-by-line basis, reducing the conversion time.
- A pseudocode uses statements that bridge the gap between actual programming and ordinary language.
- A programming language is intended for expressing computer programs and is capable of expressing any computer program.
- Machine Level Language consists of codes in the form of 0’s and 1’s and does not need a translator because the computer understands it.
- Assembly Level Language uses symbolic codes, and assemblers convert assembly programs to machine code.
- High-level language is closer to English language and is also called a procedure-oriented language.
Computer Programs
- A computer program is a sequence of instructions written with a computer programming language for the computer to perform specified tasks.
