Computer Engineering Subject
DIRECTORATE OF TECHNICAL EDUCATION, CHENNAI-25 DIPLOMA EXAMINATIONS-APRIL-2019 DEPT : COMPUTER ENGINEERING SUBJECT : MOBILE COMPUTING QCODE/SUB CODE : 915/35262 PART -A 1. Define LAN.[ 2 marks] A local-area network (LAN) is a computer network that spans a relatively small area. Most often, LAN is confined to a single room, building or group of buildings, however, one LAN can be connected to other LANs over any distance via telephone lines and radio waves. 2. What is meant by Adhoc? [ 2 marks] An ad hoc network is a network that is composed of individual devices communicating with each other directly. The term implies spontaneous or impromptu construction because these networks often bypass the gatekeeping hardware or central access point such as a router 3. What is GSM network? [ 2 marks] GSM stands for Global System for Mobile Communication. GSM is the most widely accepted standard in telecommunications and it is implemented globally. It is a digital cellular technology used for transmitting mobile voice and data services. 4. Write the limitation of GPRS. [ 2 marks] Although GPRS will provide better data rates than is currently available, there are some limitations. • Speeds of 177.2kbps would require a user to use all eight timeslots without any error protection - which simply won't happen. Initial terminals are likely to use only 1-3 timeslots anyway, limiting the available bandwidth to a GPRS user. • When GPRS packets are sent to a destination they are sent in all different directions - allowing for the potential for one or some of those packets to be corrupted or even lost altogether during the data transmission over the radio link.

Meego Interview Questions and Answers Guide
MeeGo Interview Questions And Answers Guide. Global Guideline. https://www.globalguideline.com/ MeeGo Interview Questions And Answers Global Guideline . COM MeeGo Job Interview Preparation Guide. Question # 1 What is MeeGo? Answer:- MeeGo is a Linux kernel-based free mobile operating system project resulting from the fusion of Intel's Moblin and Nokia's Maemo operating systems. Primarily targeted at mobile devices and information appliances in the consumer electronics market, MeeGo was designed to act as an operating system for hardware platforms such as netbooks, entry-level desktops, nettops, tablet computers, mobile computing and communications devices, in-vehicle infotainment devices, SmartTV / ConnectedTV, IPTV-boxes, smart phones, and other embedded systems. Read More Answers. Question # 2 Tell me which is best os ios or windowsphone or android or meego? Answer:- Meego doesn't stand a chance because of it's limited availability, and the fact that it's just overly simplistic. If you want simplicity, go for Windows Phone or iOS. It doesn't even deserve to be on the list. Windows Phone is my second choice out of all the phone operating systems. Its's very simple and elegant (even more than iOS), and is extremely stable. You will also be able to link it with Windows 8 when it comes out, and there's a possibility you could eventually run the full Windows 8 on it if it's fast enough. The only downside is that the app store is a bit small, and only has the basics currently. Read More Answers. Question # 3 What is system requirements for MeeG? Answer:- MeeGo provides support for both ARM and Intel x86 processors with SSSE3 enabled and uses btrfs as the default file system.

Porting Nemo Mobile and Mer Project to New Hardware
Porting Nemo Mobile and Mer Project to new Hardware Marko Saukko [email protected] Twitter: @markosaukko Twitter hashtags: #nemomobile and #merproject Outline ● Generic notes ● Mer Platform SDK ● Adaptation points – Kernel, Graphics, Xorg, Sensors, Audio, usb, etc. ● How to build image for your adaptation – Packaging, patterns, kickstarts, image building.. General notes .. ● After this presentation listener should know what are the adaptation points needed and where to start the new adaptation for Mer and Nemo ● As Nemo is build on top of Mer, Mer dependencies/requirements also apply to Nemo ● Mer and Nemo contain as few hw adaptation bits in the main repos as possible – Exception, e.g., mesa llvmpipe Nemo Mobile – Report problems to bugzilla ● https://bugs.merproject.org/ Mer Core ● https://bugs.nemomobile.org HW Adaptation .. continue ● When building hardware adaptation one should not need to (re)compile any of the components that are located in Mer or Nemo repositories ● Usually normal Nemo image contains around 500 packages from which 5-20 are from the hardware adaptation ● This presentation does not go through all of the details of certain components, but aims to give the general overview of points where adaptation is needed Mer Platform SDK ● NOTE: Platform SDK, not Application SDK ● All the tools that you need – Scractchbox 2, mic, osc, mer-kickstarter, ... ● Works on any typical Linux distribution, with kernel >= 2.6.37 ● Very easy to install see tl;dr; guide in wiki ● https://wiki.merproject.org/wiki/Platform_SDK Mer Hardware Requirements ● There are no real minimum requirements ● Can work on pretty much anything, e.g., – N900, N950, N9 – Nexus 7 – Pandaboard – Snowball – Rasperry Pi – ExoPC, Lenovo Ideapad S10-3t, ..
