Checking Divisibility of a Number - Aptitude Skills Program Training in SLA Chennai

You can check if a number is divisible by 2, 3, 4, 5 and so on till 13. There are some simple rules to check divisibility. Let us look at some examples for divisibility by 3 and 4.

Divisibility by 3

-------------------

A number is divisible by 3 if and only if the sum of the digits is divisible by 3.

Example:

Which of the following two numbers is/are fully divisible by 3: 97533222 or 97533322?

Answer: 97533222

Reason:

Sum of digits for 97533222 = 33 / 3 = 11

Sum of digits for 97533322 = 34 / 3 = 11.33

Divisibility by 4

--------------------

A number is divisible by 4 if and only if the last 2 digits is a number divisible by 4.

Example:

Which of the following two number is fully divisible by 4: 5555444446 or 5555444448 ?

Answer: 5555444448

Reason:

Last 2 digits for 5555444446 are 46, 46 is not fully divisible by 4 (46/4 = 11.5)

Last 2 digits for 5555444448 are 48, 48 is fully divisible by 4 (48/4 = 12)

Computer Hardware & Networking Job-Oriented Courses - SLA T Nagar Chennai Complaints

When you are working with computers, you would have wondered about how and where data is centrally stored. Or about how the client computers get information. Then you should know more about servers.

Servers come in many shapes and sizes. They are a core component of the network, providing a link to the resources necessary to perform any task. The link the server provides could be to a resource existing on the server itself or a resource on a client computer. The server is the “leader of the pack,” offering directions to the client computers regarding where to get what they need.

Servers offer networks the capability of centralizing the control of resources and security thereby reducing administrative difficulties. They can be used to distribute processes for balancing the load on computers and can thus increase speed and performance. They can also compartmentalize files for improved reliability. That way, if one server goes down, not all of the files are lost.

Servers can perform several different critical tasks. For example, servers that provide files to the users on the network are called file servers. Likewise, servers that host printing services for users are called print servers. Servers can be multi-purpose or single purpose. If they are multipurpose, they can be for example, both a file server and a print server at the same time. If the server is a single-purpose server, it is a file server only or a print server only. Another distinction we use in categorizing servers is whether they are dedicated or non-dedicated.

The TCP/IP Protocol Suite - Computer Networking Training in Chennai

The TCP/IP suite of protocols provides a set of standards for how operating systems and applications communicates and how networks are interconnected. The TCP/IP suite of protocols maps to a four-layer conceptual model known as the Department of Defense (DOD) model. The four layers are as follows:

Network Access Layer – The network access layer is responsible for placing data on the network medium and receiving data off the network medium. This layer contains physical devices such as network cables and network adapters.

Internet Layer – The internet layer is responsible for addressing, packaging, and routing the data that is handed down to it from the transport layer. There are four core products in this layer: IP Address Resolution Protocol (ARP), Internet Control Message Protocol (ICMP), and Internet Group Management Protocol (IGMP)

Transport Layer – The transport layer protocols provide communication sessions between computers. The desired method of data delivery determines the transport protocol. The two transport layer protocols are TCP and User Datagram Protocol(UDP).

Application Layer – At the top of the model is the application layer, in which applications gain access to the network. There are many standard TCP/IP tools and services in the application layer, such as File Transfer Protocol (FTP), Telnet, Simple Network Management Protocol (SNMP), DNA, and so on.

The MCSM - Microsoft Certified Solutions Master Certification Courses Training in Chennai

MCSE and MCSD certifications are prerequisites for some of the Microsoft Certified Solutions Master (MCSM) certifications. These certifications better prepare you to pursue an MCSM certification by validating the full range of skills and abilities required to be successful at building technology solutions. MCSE and MCSD certifications also validate more difficult skills than the Microsoft Certified IT Professional (MCITP) and help to bridge the gap between the MCITP and the level of knowledge required for Master-level certifications.

Microsoft Certified Solutions Master (MCSM) certifications validate skills that are deeper and broader than those validated by MCM certifications, skills that are required to build solutions both on-premises and in the cloud. Microsoft added recertification requirements to ensure that IT professionals who hold our certifications are up-to-date on our continually evolving technology. MCSM certifications require recertification every three years.
