Before IT Software Jobs Interview Student Must Aware About What IT Software Is?
IT software refers to any computer program that manages information technology systems; i.e., computers and networks. The term IT (Information Technology) encompasses many different disciplines including hardware maintenance, network infrastructure management, application development, system administration, security, etc.
It is often referrer to as “Software” or “IT Software” but should not be confuse with general purpose operating systems, database management systems, or web applications. An IT technician may work using a combination of these tools depending on the project they are working on.
The field of IT is constantly evolving and changing. New technologies and changes in business priorities necessitate new software solutions to address these emerging challenges. In some cases, old problems need to be solve with new approaches. As such, there are constant developments in the field and new software emerges providing newer and better ways to solve existing problems and meet future demands.
This means that IT technicians are continually face with the challenge of finding more efficient ways to tackle their projects. To do so, the IT professional must have access to modern software. These programs allow them to effectively analyze and manage data, automate tasks, streamline processes, improve customer service, and much more.
In order to achieve these goals, they must first determine what kind of software is best suited to address their specific requirements. There are two types of software – open-source software and proprietary software. Open-source software is free while proprietary software is not. Both of these types of software have pros and cons and each type comes with its own advantages and disadvantages.
So, how does one decide between the two? Well, the answer lies in the fact that both types of software have been around long enough to gain a solid reputation and provide users with real value. Proprietary software has proven itself over time while open-source software relies on open standards that are recognize across the industry. If you want to find out if your company uses proprietary or open-source software, you can simply ask your IT department.
Proprietary and open-source software also differ in terms of cost. Proprietary software tends to be expensive compare to open-source software. However, the latter is not always the case. In some instances, open-source software can be just as costly as proprietary software. You can read reviews online to help figure out whether a particular piece of software is worth investing in.
There are many other factors to keep in mind before making a decision. What is the budget and timeframe involved? How much training and support will the software require? Is the software user friendly? Does it provide reliable results? Do you need extensive customization options? Will a custom version of the software be necessary? All of these questions will help you make an informed choice and choose the right software for your unique needs.

C and C++ are two popular programming languages used today in many different fields. Both languages can run on a wide variety of hardware configurations.
Java is a general-purpose, multi-threaded object oriented programming language designed primarily for writing programs that require extensive use of dynamic memory allocation. Most Java applications are written in the Java Standard Edition (JSE) platform and run on Linux, BSD, Solaris and Windows systems.
Python is a high-level, interpreted, object-oriented scripting language. It was developed by Guido van Rossum at CWI in 1990 and first released in 1991. It is open source, free software released under the terms of the GNU General Public License. Python supports modules, exception handling, classes, exceptions, generators, numeric types, strings, lists, arrays, dicts, sets, file input/output, etc.
Ruby is a dynamic, reflective, object-oriented, general purpose programming language created by Yukihiro Matsumoto in 1993. Its syntax borrows heavily from Perl 5 and Smalltalk. A number of dialects are commonly referred to as Ruby, including MRI Ruby and YARV Ruby.
(Hypertext Preprocessor) is a widely used general-purpose scripting language. PHP runs on the Apache HTTP Server. Other web servers may work without modifications.
Perl is a general-purpose scripting language. Originally released in 1987 by Larry Wall, it was conceived as a successor to AWK and sh. Its syntax borrows heavily from Algol 60’s family of languages, including its operator precedence rules, case sensitivity, and variable scoping. It also contains much lexical scope, making it similar to shell scripts. In addition, Perl offers some unique extensions beyond those offered by shells, notably regular expressions, symbolic references, and threads.
SQL stands for Structured Query Language; it is a declarative language used for data storage and retrieval, as well as data analysis. SQL is standardized by ANSI and ISO/IEC standards, and implemented by various vendors.

Let’s Discuss What is IT Hardware & IT Hardware Jobs
IT Hardware can be define as a combination of hardware devices (hard disk drives, CD-ROM’s, CPU’s) and software programs (operating systems, applications, etc.) that have been designed to work together. Each piece of hardware has its own particular function and role within the system. The term “computer” refers to the whole interrelated set of hardware and software that enable users to communicate with each other over networks.
A computer can be composed of many different components, but each component has exactly the same purpose – to perform a specific task. When a user types something into a word processor, the processor translates what was typed into electrical impulses and sends them to the printer. Without any of these parts, the entire machine would not function properly.
A central processing unit (CPU) is the electronic circuitry inside a computer processor, responsible for executing instructions given to it by an operating system or application program. In general, CPUs take electrical impulses, call electrons, derived from electricity and convert them into binary ones and zeroes that represent operations to be performed by the processor. A CPU contains registers and arithmetic logic units (ALUs), where data manipulation takes place.
A motherboard is the primary circuit board inside a PC chassis, containing sockets for expansion cards, connectors for video devices, slots for memory modules and various other components. Motherboards are design to fit specific motherboards, so they have a standardize socket arrangement with defined pin-out patterns.
Random access memory (RAM) is a type of volatile storage used by a computer’s microprocessor, either built into the same chip or elsewhere on the circuit board. RAM holds programs and data while it is being processed. It is generally considered one of the three major functional categories of computing hardware (along with ROM and disk drives).
4. Hard drive
Hard drive is a non-removable mass storage device consisting of platters coated with magnetizable material arranged in a rotational drum that spin at high speed to provide fast access to stored data. Data is access by head-positioning mechanism. Data is read onto or off of the magnetic coating on the surface of the rotating platter. The heads may move radially to different tracks on the platter. The recording density is determine by track width, linear bit density and the number of linear bits per inch along each track.
Monitors display information from the host computer. Also Monitors vary in size, shape, and purpose. Most monitors operate using analog signals, which change their voltage based on the intensity of light directed towards them. There are two types of monitors: cathode ray tube (CRT) and flat panel displays (FPD). CRTs were the predominant monitor technology for many years, but FPDs are now dominant in desktop computers due to their smaller size, lighter weight, lower power consumption, higher resolution, longer operational life, and less expensive manufacturing cost compared to CRTs.
6. Optical disc
Optical discs are digital media capable of storing large amounts of data. Common optical discs include Compact Discs (CDs) and DVDs; some Blu-ray Discs currently store 25 GB. CDs can store about 650 MB of data, whereas DVDs can store between 4.7 GB and 17 GB. Blu-ray disks can hold roughly 25 GB.
7. Network interface card (NIC)
Network Interface Cards (NIC) are integrated circuits that connect a personal computer or server to a network. NICs provide the physical connection between the computer and the network. The most popular form of NIC is Ethernet, which provides transmission speeds around 10 megabits per second (Mb/Ps). Other forms of network interfaces include Token Ring and Fast Ethernet.
