1011\(_2\) = 1 × 2\(^3\) + 0 × 2\(^2\) + 1 × 2\(^1\) + 1 × 2\(^0\)
1 × 8 + 0 × 4 + 1 × 2 + 1 × 1 = 8 + 0 + 2 + 1 = 11
122\(_4\) = 1 × 4\(^2\) + 2 × 4\(^1\) + 2 × 4\(^0\)
1 × 16 + 2 × 4 + 2 × 1 = 16 + 8 + 2 = 26
11 + 26 = 37

Cache memory is a very high speed semiconductor memory which can speed up CPU, it acts as a buffer between the CPU and main memory

An assembler converts assembly level language code into machine language code while a compiler converts high level programming language code to a machine language code

Translators are a type of system software. They are used to convert source code written in one programming language (the source language) into another programming language (the target language). Examples of translators include compilers, interpreters, and assemblers. System software is a type of computer software designed to run a computer's hardware and application programs. It includes the operating system, device drivers, diagnostic tools, servers, windowing systems, utilities, and more

During the System Analysis stage of the System Development Life Cycle (SDLC), all data are documented in the form of detailed Data Flow Diagrams (DFDs). The System Analysis stage involves understanding and documenting the business processes and requirements of the new system
