Networking explained

network and routers explainedA network router is a more sophisticated network device compared to either a network switch or a network hub. Like hubs and switches, routers are typically small, box-like pieces of equipment that multiple computers can connect to. Each features a number of ports on the front or back of the unit that provide the connection points for these computers, a connection for electric power, and a number of LED lights to display device status. While routers, hubs and switches all share similar physical appearance, routers differ substantially in their inner workings. 


Why not linux?

OUbuntu Linuxur understanding of personal computer is evolving at an ultra fast pace, the advent of mobile computing and the “tablet” revolution have changed the way we live and interact with each other, however, I don’t think that the “Tablet era” will last that long, still our home PC will survive if not prevail.


Is your PC hack proof..?

PC securityFollowing the news and revelations about security concerns raised by the NSA actvities.

Now that we’ve come to know what security services and government agencies can do we start to realise that actually privacy is nothing true. No matter how loud are websites screaming about their policies about cookies, as you might have noticed since a month or so all major web sites are adding an alert when you visit their web site asking to acknowledge that cookies are enabled. In other words also this web sites are collecting data……everyday, every time you visit…and not only.


SSD Drives

solid state drives explainedBefore we talk of SSD Drives, (picture on the top left), let’s just review what we know of mechanical hard drives, (picture on the bottom right), which are still the most common used storage on commercial PC.

Mechanical Hard drives are made of metal spinning platters with a magnetic coat that stores and retrieves data written to it via an harm with an head at the end, (looking like the one in the old turntables). Hard Drives are “nonvolatile” memory, so the data stays stored on the disk even when the system is powered off. 


Wi-Fi (802.11ac) explained

WiFi 802.11 AC explained802.11ac or 5G Wi-Fi: This latest Wi-Fi standard operates only on the 5GHz frequency band and offers Wi-Fi speeds of up to 1.3Gbps (or 1,300Mbps).

It’s backward-compatible with N, meaning that a 5G Wi-Fi router will support N clients and 5G Wi-Fi clients will also be able to connect to an N router. Wireless-N, in turn, is backward compatible with the rest of the wireless standards, including 802.11g, 802.11b, and 802.11a.


Memory running low..?

A very good day to you all and welcome to DIY corner. Today we are going to talk of how to upgrade your Memory RAM Modules.

Laptop ram ugradesPre arrangements:

By using your Windows System info software, or checking online at the vendor web site for your laptop, determine the specification of your existing Ram modules. In this case we have a DDR2 667MHz PC2-5300 200pin 


What is a router anyway?

understanding routersAs the name implies, a router is the device that routes the requests for web content from your LAN, (local area network), such as all your computers, mobiles, tablets and any other device at home that can connect to the internet with the WAN, (wide area network), external internet services or the web itself.


Network over the Mains

Network over the MainsHomePlugs, Powerlines or Network over the Mains, However you call them.

Powerline networking adaptors aren’t all that well known, but are enormously useful. Instead of stretching Ethernet cables from room to room, Powerline technology allows you to create a network using the existing mains electrical wiring in your home or office.
