it’s no secret that learning to code is something that’s quite difficult a lot of people have trouble with it they give up they can’t get far enough into it to find it interesting and it’s just something that a lot of people are trying to get into nowadays but can’t get past those beginner levels.

The first and probably the most important mistake I see people making all the time is memorizing and not understanding now what I mean by that is when you learn something new the tendency for a lot of courses a lot of people they’re…


I have been a Computer Engineer for over 3 years now, so I think I can speak to what skills you need to learn in rough order of complexity:

  1. Math. Math is the language of Engineering. If you can’t speak the language at least a little you are hopeless.
  2. Physics/Fields & Waves / Thermodynamics. You need to understand at some level how the universe you intend to manipulate works.
  3. Circuit Analysis. Without understanding how electricity flows and works with various basic components you are nowhere.
  4. Digital logic. Learn to use transistors to build gates and flip-flops, then combine those gates…

1.Install apps from other sources than Playstore: This doesn’t seem to bother many users, but the downside is such apps may contain malware or they may use your device information, etc., to sell for third party markets

2.Not reducing Screen on(Sleep) time: If it is not required, you can reduce your screen on time to the least possible say (15 or 30 secs). This small change along with reducing your brightness while indoor usage may substantially improve your battery performance

You can even reduce your screen brightness to the minimum possible by using apps like screen dimmer from Playstore.

3.Install…

A firewall is a guard b/w your computer or your internal network and the outside world or the Internet. A particular firewall implementation may use one or more these types of methods :

Packet filtering 

Stateful packet filtering 

User authentication 

Client application authentication

A firewall will filter incoming packets based upon these parameters such as packet size, source IP address, protocol, and destination port. Linux and Windows operating systems come up with a simple firewall. There are two best personal firewall solution provider for individual PCs

Norton

McAfee

These firewalls are meant for individual machines. There are…


You can execute some network utilities from a command prompt (Windows) or from a shell (Unix/Linux). Many people are already familiar with Windows, so we will focus on how to execute the commands from the Windows command-prompt perspective. However, these utilities are available in all operating systems.

Network Utilities

Ipconfig

The first thing you want to do is get information about your own system. To accomplish this, you must get a command prompt. In Windows, you do this by going to the Start menu, selecting All Programs, and then choosing Accessories. You can also go to Start, Run, and type cmd to get…


you need to send data (whether it is physical or wireless). The first part is to identify where you want to send it. All computers (as well as routers and switches), have an IP address that is a series of four numbers between 0 and 255 and is separated by periods, such as 192.168.0.1.

The second part is to format the data for transmission. All data is in binary form (1s and 0s). This binary data is put into packets, all less than about 65,000 bytes. The first few bytes are the header. That header tells where the packet is…
