Answer:
The attached files contain the realization of a D flip-flop from an RS flip-flop. It also contains the truth tables for both kinds of flip-flops
Explanation:
An SR flip flop is like a light switch. Set turns it 'on' and reset turns it 'off'
A D type flip-flop is a clocked flip-flop which has two stable states. A D type flip-flop operates with a delay in input by one clock cycle.
D type flip-flops are easily constructed from an SR flip-flop by simply connecting an inverter between the S and the R inputs so that the input to the inverter is connected to the S input and the output of the inverter is connected to the R input.
Answer:
Check your DNS settings
Explanation:
Different errors may occur when setting up your computer to connect to the internet, one of which is described in the question above.
The DNS (Domain Name System) is responsible for redirecting domain names to their physical IP address. Instead of remembering every IP address of sites you visit frequently, domain names are used for easy remembrance, the DNS makes the matching of domain names to IP addresses possible.
To change your DNS setting follow these steps:
- Click settings from your start menu
- Click on Network and Internet
- Look to the bottom of the main page and click on "Network and Sharing Center"
- On the left tab, click "Change adapter settings"
- Right Click on the current network you are using and select properties
- Left-click on the "Internet Protocol Version 4 (TCP/IPv4) and click on properties.
- Check to see if "Obtain DNS server address automatically" is selected, if it is selected,
- Click on the radio button under it "Use the following DNS server address"
- Enter the DNS address you want to use
- Click Ok and close the window.
The problem should be resolved.
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.
