break Statement The break statement is used to alter the flow of control. When a break statement is executed in a while loop, for loop, do-while loop or switch statement, it causes immediate exit from that statement. Program execution continues with the next statement. Common uses of the break statement are to escape early from a loop or to skip the remainder of a switch statement. The program written below demonstrates the break statement in a for-loop. When the if-statement detects that x has become 5, break statement is executed. Read More

Remote desktop is essentially an operating system utility, or individual software that permits users to access other computers within a network or through the internet, from another computer, laptop, smartphone, or any other internet-enabled device. In an office environment, various applications can be installed on a remote server, and users can login to the server via remote desktop and use the installed applications. This sort of set up enables users to work with applications without the burden of installing them on their own computer or laptop. This saves space and Read More

A SIMM, or Single In-Line Memory Module, is a printed circuit board that is designed to hold multiple RAM chips at a time. SIMMs provide computers with additional RAM that could not be provided by a single RAM chip and allow for a tier-based memory system. While SIMMs have been widely replaced with DIMMS, or Dual In-Line Memory Modules, they are still commonly found in 32-bit personal computers and can even be used in 64-bit computers when two SIMMs are installed together. How SIMM Works SIMMs are available in a Read More

802.1p is an IEEE standard that describes mechanisms to prioritize traffic and perform dynamic multicast filtering. Because of its support for priority specification, 802.1p is important for providing Quality of Service (QoS) for better reliability and quality. Quality of Service QoS is a mechanism that allows for better handling of data that passes over a network. There are two major types of Quality of Service (QoS) techniques, hard QoS and soft QoS. Hard QoS has a hard-set capacity reserved for certain types of service, while soft QoS just deals with Read More

An M4A file (MPEG-4 Part 14) is an audio file developed for QuickTime and other MP4 players. Essentially, an M4A file is the same as an MP4 or MOV file, but specifically defines MPEG features and stores audio rather than video. M4A files contain file compression algorithms that allow them to be much smaller than other audio formats, such as MP3 and WAV, while maintaining high quality. They are specifically designed to be used with QuickTime and other Apple products, but a wide variety of media players can also use Read More

Groups are containers that contain user and computer objects within them as members. When security permissions are set for a group in the Access Control List on a resource, all members of that group receive those permissions. Domain Groups enable centralized administration in a domain. All domain groups are created on a domain controller. In a domain, Active Directory provides support for different types of groups and group scopes. The group type determines the type of task managed with the group. The group scope determines whether the group can have Read More

Facebook is a great way to connect with others. Although Facebook users enjoy connecting with others, they may not want some of their contacts to see the friends they have made or the contacts on their account. In order to make friends invisible on a Facebook profile page, privacy settings must be adjusted. This can be achieved by the following process: Log on to Facebook. Select the “Account” tab from the upper right corner of the page. Select “Privacy Settings” from the drop down list. This leads to the ‘Choose Read More

YouTube also hosts material from major media companies such as BBC, CBS, and VEVO. File Formats Supported by YouTube YouTube states they can accept most video file formats. However, some formats are preferred. The following are a few of their most popular file types: WebM Files .MPEG4, 3GPP, Read More

Angular acceleration is the rate of change of a body’s angular velocity compared to time. It is considered a vector quantity since it has a direction and magnitude. Angular acceleration is similar to linear acceleration except that it travels on an arc. Scientifically, it is equal to (final angular velocity – initial angular velocity) / time. A body’s angular velocity is the rate of change of angular distance with respect to time and acceleration is the rate of this change over the same time frame. How is Angular Acceleration Measured?

DVB-RCS stands for Digital Video Broadcast – Return Channel Satellite. DVB-RCS is part of the DVB standards for satellite communication, DVB-S and DVB-S2. The purpose of DVB-RCS is to provide a return channel to enable Internet and other data services over satellite. ViaSat’s LinkStar system is one of the VSAT satellite broadband implementations which support DVB-RCS. The DVB standards are maintained by the DVB Project, which is an industry-led consortium of over 260 broadcasters, manufacturers, network operators, software developers, regulatory bodies and others in over 35 countries. DVB-RCS is officially Read More
