As Viet drives around and checks meters to document the amount of electricity used in homes he would be part of the energy distribution process since the electricity is distributed off a power line into the house and then within the house by the wiring to the lights and the electrical outlets for usage by the inhabitants.
Answer:
1GL: Machine language. Represented by a series of 1s and 0s.
2GL: Assembly language. An assembler converts 2GL into machine language.
3GL: High-level programming language. Uses a compiler to convert into machine language.
4GL: Specifically designed for creating database management programs.
5GL: Extremely advanced. Uses statements (scripts) rather than algorithms.
Explanation:
Programming languages started as a series of binary digits (i.e. 0's and 1'). This generation of language is referred to as the first generation.
However, the machine language were difficult to read by human, so mnemonics were created (i.e. assembly language). This language uses symbolic codes such as ADD for addition, etc. This is the second generation
The third generation are the high level languages that uses languages that can be easily understood by human, e.g. + means plus. However, the language must be translated; hence the need for a compiler or interpreter, as the case may be.
The fourth and fifth generations are extensions of the third generation languages. The fourth were created to connect to DBMS while the fifth are more advanced.
Answer: Detailed
Explanation:
SDLC consist of 7 phases. They are:
1. Planning.
2. System analysis and requirement
3. Design:
4. Coding:
5. Testing:
6. Installation
7. Maintenance
Here we are talking of the third phase. In this phase it is the design phase which consist of high and low level design. Here the preliminary design is included in high level design where it describes the required hardware, software, network capabilities and the modelling of the interface. However the detailed design in low level design will implement the coding and will finding of any errors in the implemented design as described by the preliminary design.
Answer:
a. PCI express
Explanation:
<em>PCI express</em> (Peripheral Component Interconnect Express) is a high speed serial bus and commonly used motherboard interface for Graphics card, wifi, SSDs and HDs hardware connections. Simple PCI can also be used but PCI express has more error detection accuracy lesser number of I/O pins and better throughput as compared to simple PCI.
