There are also many other types of work available in the outsourcing world. . Freelancing Freelancing  means working independently without being under a specific person or orga...

Data Transmission System Asynchronous Transmission: A data transmission system in which characters are transmitted from sender to receiver is called asynchronous transmission. In this method the sender does not require any primary storage medium for data transmission. Main features of asynchronous data transmission: (i) The sender does not require any primary storage device for data transmission. (ii) In this method of data transmission the sender can transmit the data at any time and the receiver can also transmit it. (iii) In this method of data transmission, the time between the transmission of one character and the transmission of another character may vary rather than be equal. (iv) Each character has a start bit at the beginning and end transmission is also called start/stop transmission. Advantages, Disadvantages and Uses of Asynchronous Data Transmission Advantages of asynchronous data transmission: (i) At any time the sender can send data and the receiver can receive it. (ii) ...

  Analog and Digital Transmission Analog Signal: The system in which variable signal i.e. the signal can have any meaning at any time, is called analog signal. This signal is used for data processing in analog devices like radio, TV etc. The wave/shape of an analog signal is-- Digital Signal: The level of the signal is variable, i.e. the level of the signal changes over time in a certain step, it is called a digital signal. This signal is used for data processing in digital devices like computers, digital clocks etc. The wave/shape of a digital signal is-- Carrier Signal: Carrier signal is a type of high frequency signal, which is used as a carrier wave to transmit electrical signals to distant places. - The wave/shape of carrier signal is the difference between analog, digital and carrier signal: The difference between analog, digital and carrier signal is given below-- Analog signal (i) A system in which the signal is variable i.e. the signal can have any value at any time, is ca...

Connectors The cable connector is the daughter device between the network card and the cable. That is, it connects the network cable and (NIC). Notable among cable connectors are coaxial cable, 10 bit, Ethernet etc. Among them, 10 bit connector is comparatively much faster, reliable and widely used. The 10-pin connector looks a lot like a telephone wire. Some network cards support multiple connector types, thus providing multiple ports. Such cards are called combo cards. Recently, Ethernet technology has gained great popularity in the world of networking, to say that now Ethernet is a dominating (Dominating) technology. For that reason, if the network card of the computer is of combo type, then it is possible to upgrade it to use Ethernet technology. The following three types of connectors are commonly used in networks. These are-- a) RJ-45: It is used to connect UTP cable to network interface card or NIC. This connector has a total of 8 contact pins. These 8 pins are used in different...

Organization of Program A set of instructions used by a computer to solve a problem is called a program. These instructions are generally divided into three parts, namely, input, processing and output. That is, how many instructions are used for inputting data, how many instructions are used for processing and how many instructions are used for displaying output. The relationship between these instructions is shown below in the diagram: Instructions to input ↓ Instructions for data processing ↓ command to provide output Program development steps : There are several sequential steps to be followed in the process of writing a program and executing it on a computer to perform various tasks. Each step is discussed in detail below: (1) Investigation (2) Problem analysis (Problem analysis) (3) Program design (4) Program coding (Program coding) (5) Program testing, debugging and implementation (Program testing, debugging and implementation) (6) Program maintenance  1. Finding information:...

 Search Engine Optimization There are many search engines in the world, such as the most famous is Google, followed by Yahoo, Bing etc. If someone wants to learn HTML in Bengali, he might search Google by writing "HTML Tutorial", because he might not know the address of any website that has HTML Tutorial in Bengali. Now let's say there is a website that has HTML Tutorial in English. Now if "HTML Tutorial" If you search on Google by writing ", the first link on the first page of Google is the site, then the user who was searching for "HTML Tutorial" will definitely go to that site. This one's site showed up first on Google, even though there are many sites, blogs, forums etc. that have HTML in Bengali, the site that showed up first had adopted some techniques, these techniques are called Search Engine Optimization (SEO). -Search Engine Optimization (SEO) is mainly of 2 types, namely-- 1. On Page (which is done within the site, ie- title tags, c...

Hotspot, Wi-Fi, Wi-Max, Bluetooth Hotspot: Hotspot is a type of wireless network that provides internet connection to mobile computers and devices such as smartphones, PDAs, tablets, netbooks, notebooks or laptops. Currently, the three popular hotspot technologies are – 1. Wi-Fi 2. Wi-Max 3. Bluetooth Wi-Fi: Wi-Fi or wireless fidelity is a popular wireless technology that uses radio waves to connect any electronic device to a high-speed Internet connection or computer network to exchange data. It is technically known as IEEE 802.11b. Wi-Fi technology is relatively faster (11 Mbps) and less expensive than standard Ethernet and other common wired LAN technologies. Thus, the Wi-Fi wireless LAN connects laptop PCs, PDAs, smart phones, tabs and other devices with Wi-Fi modems to the rapidly growing business, public and the planet to easily connect to the Internet and other networks. A faster version (802.11g) with a speed of 54 Mbps promises widespread use of this technology. Features of Wi...
