What Is a Core Switch Backplane?

Function

A core switch located on a backplane connects edge switches. An edge switch is a switch placed where two network's hardware systems meet. Examples of edge switches include multiplexers and routers. Edge switches are also referred to as service or access nodes.

Identification

Core switch backplanes are often referred to as tandem or backbone switches. A computer's core is synonymous with its central processing unit (CPU.)

Features

The word "backplane" is often considered to be synonymous with a computer's motherboard. They control computing paths through socket connections not only to other circuit boards, but also to expansion cards and other electronic devices.

Backplanes are considered active if they contain circuitry that conducts computing functions. Passive backplanes do not contain circuitry and are not responsible for anything but serving as connectors.

BIOS Resource Conflicts

Symptoms

The computer can manifest a range of symptoms if a resource conflict is present. The system may freeze or hang, especially when a peripheral device is in use. The computer or peripheral devices may make excessive noise during operation. Sound from an audio card may be distorted or unclear. The screen may display random characters. The mouse may move very slowly or not work at all. The printer may print nonsense. Applications may crash or experience random errors. The computer may be unable to format media. Data may incorrectly transfer from various devices.

Static Resource Conflict

If your system BIOS reports a "Static Resource Conflict," it is most likely due to a Plug and Play device. PNP devices are peripherals, such as video or audio cards, which work with the computer system without installing additional software. The user simply plugs the device into the computer's system board. The BIOS may misread the location of the PNP device and assign more than one location to it. Possible solutions for this problem are: rebooting the system, updating or flashing the system BIOS, updating PNP device drivers or removing the PNP device.

Device Manager

If your system detects a resource conflict, you may be able to solve the problem in Windows. Getting to Windows may require that you start the computer in Safe Mode. The Device Manager shows what resources each peripheral device uses. You can disable these devices through the Device Manager, if needed.

Hardware Issues

Hardware incompatibility may cause resource conflicts. Your system may not be able to support all peripheral devices equally. Consult your computer user's manual for device compatibility. Most manufacturers offer online support to ascertain device compatibility, even for legacy systems and hardware. In addition, outdated hardware drivers may be responsible for resource conflicts. Check with your computer manufacturer for driver updates.

Viruses

If the system BIOS detects a resource conflict, but none exists, a computer virus or malware may be responsible. Perform a complete system scan using your preferred anti-virus application. Free applications are available online if you do not currently have any installed. Removing the virus should remedy the conflict.

Comparing Portable Scanners

Bundled Software and Compatibility

1. Some scanners come with bundled software and others do not. The software is not necessary, but it can speed up the process of scanning and organizing documents. Look for a scanner that has comes with bundled software.
   Your computer needs to meet the minimum requirements and have the correct operating system in order to run the software. If requirements are not met, the scanner will not work for your computer.

Scanning Speed

2. Scanning speed varies per model. For fastest speeds, choose a scanner with a low resolution and black and white output. A higher resolution and color output will cost you in speed, but the scan will be higher quality.
   The power source also affects scanning speed. A scanner with an AC adapter will scanner faster than one powered through a USB port.

Weight

3. Another factor to consider when comparing portable scanners is weight. When traveling, a lighter scanner might be important to you. Typically the power source is not included in the stated weight.

Synaptics Mouse Driver Problems

Driver Replacement

If the mouse pointer fails to operate correctly after upgrading the operating system, you cannot change the software's advanced settings or the mouse wheel on a PS/2 or USB mouse does not operate, you need to replace the outdated, malfunctioning or inappropriate Synaptics driver with a new one. Since each manufacturer has its own specific hardware setup, download the driver from the system manufacturer's website.

Erratic Mouse Behavior

Erratic or randomly jumping pointer problems on a Synaptics device may be addressed from the software driver's settings. Change the "PalmCheck" and "Touch Sensitivity" settings from the device's Properties window in the Control Panel.

Driver Conflicts

The Synaptics driver will not operate correctly if another conflicting mouse driver is installed. You must remove any other drivers and sometimes reinstalling the correct Synaptics drivers is necessary to restore functionality.

Ipl Kochi in IPL 4

No. of players: 17 (7 Indian, 10 foreign)
Money spent: $7.79 million
Big-ticket signing: Mahela Jayawardene ($1.5 million)
Bargain buy: Brendon McCullum ($475,000)
Eyebrow-raiser: Ravindra Jadeja ($950,000)
Ones that got away: Gautam Gambhir (Kochi bid $2.3m), Yusuf Pathan (Kochi bid $2m), Uthappa (Kochi bid $2m) 

Kochi have ten players capable of bowling four-over spells in a Twenty20 - four allrounders and six specialists - but their batting is thin, especially in terms of home talent. Their two Indian batsmen - VVS Laxman and Parthiv Patel - aren't deadly in the shortest format and at the moment the bulk of the runs will have to come from the foreign players. If that dependency doesn't change, it will hamper Kochi's chances of fielding the overseas bowlers and allrounders they have bid for. They were the first team to fill up their overseas slots.

Squad

Batsmen: Mahela Jayawardene ($1.5m), VVS Laxman ($400,000), Brad Hodge ($425,000), Owais Shah ($200,000), Michael Klinger ($75,000)
Bowlers: Sreesanth ($900,000), RP Singh ($500,000), Muttiah Muralitharan ($1.1m), Ramesh Powar ($180,000), Vinay Kumar ($475,000), Steve O'Keefe ($20,000)
Allrounders: Ravindra Jadeja ($950,000), Steven Smith ($200,000), Thisara Perera ($80,000), John Hastings ($20,000)
Wicketkeepers: Brendon McCullum ($475,000), Parthiv Patel ($290,000)

Kolkata Knight Riders in IPL 4

Kolkata Knight Riders

No of players bought: 12 (5 Indian, 7 overseas)
Money spent: $8.57m
Big-ticket signing: Gautam Gambhir ($2.4m) and Yusuf Pathan ($2.1m)
Bargain buy: Brad Haddin ($325,000) and Shakib Al Hasan ($425,000)
Eyebrow-raiser: Manoj Tiwary ($475,000). Kolkata hadn't chased any of the players they previously had in their squad over the past three years, but towards the end of the first day they decided to go after Tiwary.
One that got away: With two major buys in the first hour, Kolkata didn't have the money to raise the stakes high on too many other players.

Splashing the cash early meant they had a strong Indian batting core to rely on in Gautam Gambhir - their likely captain - and Yusuf Pathan. And, in a tournament where the strength of the Indian players determines team fortunes, they already have five players who should start most matches. They also supplemented that with three value-for-money foreign allrounders - Jacques Kallis, Shakib Al Hasan and Netherlands' Ryan ten Doeschate. One of their major drawbacks in previous seasons was the lack of a potent bowling attack, a weakness that persists with the current squad. They have Brett Lee, in his prime one of the finest limited-overs bowlers, but after being repeatedly ravaged by injury, it remains to be seen whether he retains the magic of old.

Squad
Batsmen: Gautam Gambhir ($2.4m), Manoj Tiwary ($475,000), Eoin Morgan ($350,000)
Bowlers: L Balaji ($500,000), Brett Lee ($400,000), Jaidev Unadkat ($250,000), James Pattinson ($100,000)
Allrounders: Yusuf Pathan ($2.1m), Jacques Kallis ($1.1m), Shakib Al Hasan ($425,000), Ryan ten Doeschate ($150,000)
Wicketkeeper: Brad Haddin ($325,000)

Mumbai Indians in IPL 4

No of players bought: 12 (4 Indian, 8 overseas)
Money spent: $8.52m
Big-ticket signing: Rohit Sharma ($2m)
Bargain buy: Clint McKay ($110,000)
Eyebrow-raiser: Andrew Symonds ($875,000)
One that got away: Yuvraj Singh (bid $1.7m)

When they walked into the auction, their squad already boasted the biggest name in the game, the most exciting player in the format, and the deadliest bowler in Twenty20s. They added another marquee IPL name in Rohit Sharma, besides picking up some cut-price internationals like Clint McKay, whose slower balls mystify most batsmen, and South African Davy Jacobs, a lethal hitter who can double up as a wicketkeeper. The pedigree of their squad is unimpeachable, but Tendulkar has long stressed the importance of team spirit for success - how the squad containing Andrew Symonds and Harbhajan Singh gels will be fascinating to see.

Squad
Batsmen: Sachin Tendulkar (retained), Rohit Sharma ($2m), Aiden Blizzard ($20,000)
Bowlers: Harbhajan Singh (retained), Lasith Malinga (retained), Munaf Patel ($700,000), Clint McKay ($110,000)
Allrounders: Kieron Pollard (retained), Andrew Symonds ($850,000), James Franklin ($100,000), Moises Henriques ($50,000)
Wicketkeeper: Davy Jacobs ($190,000)

Sahara Pune Warriors in IPL 4

Pune Warriors

No of players bought: 14 (4 Indian, 10 overseas)
Money spent: $8.07m
Big-ticket signing: Robin Uthappa ($2.1m), Yuvraj Singh ($1.8m)
Bargain buy: Jesse Ryder ($150,000)
Eyebrow-raiser: Robin Uthappa ($2.1m)
One that got away: David Hussey (bid $1.3m)

The new franchise wanted a headliner to connect the franchise with fans, and got one early in Yuvraj Singh. Then they splurged on a finisher in Robin Uthappa, and also got two Indian bowlers who have proven themselves in the IPL - Ashish Nehra and Murali Kartik. Their overseas signings, though, lack the X-factor that most foreign recruits are expected to bring to the side. They have two exciting allrounders in Angelo Mathews and Jesse Ryder, but the fast bowling looks dodgy with both Jerome Taylor and Wayne Parnell having had long-term injuries.

Squad

Batsmen: Robin Uthappa ($2.1m), Yuvraj Singh ($1.8m), Graeme Smith ($500,000), Callum Ferguson ($300,000)
Bowlers: Ashish Nehra ($850,000), Murali Kartik ($400,000), Wayne Parnell ($160,000), Jerome Taylor ($100,000)
Allrounders: Angelo Mathews ($950,000), Mitchell Marsh ($290,000), Jesse Ryder ($150,000), Nathan McCullum ($100,000), Alfonso Thomas ($100,000)
Wicketkeeper: Time Paine ($270,000)

Kings XI Punjab in IPL 4

Kings XI Punjab

No. of players bought: 11 (4 Indian, 7 foreign)
Money spent: $6.95 millon
Big-ticket signing: David Hussey ($1.4 million)
Bargain buy: Shaun Marsh ($400,000)
Eyebrow-raiser: Piyush Chawla ($900,000), Abhishek Nayar ($800,000)
Ones that got away: Irfan Pathan (Punjab bid $1.8m), Saurabh Tiwary ($1.5m), Mahela Jayawardene ($1.4m), Dale Steyn ($1.1m) 

While the other franchises spent and shopped over two days in Bangalore, Kings XI Punjab were sparing with their purchases and bought only 11 players. They have a little over $2 million to fill their squad with uncapped domestic players. The challenge is to pick up several high-quality ones to fill the gaps in their team. And there are many. They have only two specialist batsmen and their two allrounders are nothing to write home about. They also possess only one spinner at present. Their strengths lie in their fast bowling and their wicketkeeping reserves - Adam Gilchrist and Dinesh Karthik. Curiously, Punjab bid over a million for four other players but were never ready to go the distance to buy them, even though their purse was heavy.

Squad

Batsmen: Shaun Marsh ($400,000), David Hussey ($140,000)
Bowlers: Stuart Broad ($400,000), Praveen Kumar ($800,000), Ryan Harris ($325,000), Piyush Chawla ($900,000), Nathan Rimmington ($20,000)
Allrounders: Abhishek Nayar ($800,000), Dimitri Mascarenhas ($100,000)
Wicketkeepers: Adam Gilchrist ($900,000), Dinesh Karthik ($900,000)

Delhi Daredevils in Ipl 4

No. of players bought: 17 (7 Indian, 10 foreign)
Money spent: $8.25 million
Big-ticket signing: Irfan Pathan ($1.9 million)
Bargain buy: Andrew McDonald ($80,000)
Eyebrow-raiser: Umesh Yadav ($750,000)
Ones that got away: Zaheer Khan and Sreesanth (Delhi bid $850,000 for each)

The man raising Delhi's paddle at the auction was the fastest among all the franchises and he spent quite a bit of money, especially on Irfan Pathan, who bats and bowls but hasn't been a match-winner at either skill for some time. Delhi have several allrounders in their squad but they lack a top-class Indian batsman, apart from Virender Sehwag. They also have only one spinner in their roster of 17 players - Roelof van der Merwe. The batting line-up, however, is solid, and in Sehwag and David Warner, they perhaps have the most explosive opening combination of the IPL. They bought back only four players of their old squad and bid aggressively against Deccan Chargers for a lot of players.

Squad

Batsmen: Virender Sehwag (retained), David Warner ($750,000), Aaron Finch ($300,000), Venugopal Rao ($700,000), Travis Birt ($20,000), Colin Ingram ($100,000)
Bowlers: Morne Morkel ($475,000), Ajit Agarkar ($210,000), Ashok Dinda ($375,000), Umesh Yadav ($750,000), Robert Frylinck ($20,000)
Allrounders: Irfan Pathan ($1.9m), James Hopes ($350,000), Roelof van der Merwe ($50,000), Andrew McDonald ($80,000)
Wicketkeepers: Naman Ojha ($270,000), Matthew Wade ($100,000)

Deccan Chargers In IPL 4

Deccan Chargers

No. of players bought: 14 (5 Indian, 9 foreign)
Money spent: $6.88 million
Big-ticket signing: Dale Steyn ($1.2 million)
Bargain buy: Kumar Sangakkara ($700,000)
Eyebrow-raiser: Dan Christian ($900,000)
One that got away: Yuvraj Singh (Deccan bid up to $1.6m)

At first glance, Deccan appear light on Indian talent, especially Indian batting talent, but they have enough money left over from the auction to snap up domestic players. They are thin in the multi-skilled department as well, with surprise purchase Dan Christian being their only allrounder. They also have only one wicketkeeper at present, Kumar Sangakkara, who is likely to lead the team as well. They, however, have a rich batting line-up that includes Kevin Pietersen, Cameron White and JP Duminy, and also little-known Chris Lynn.

Squad

Batsmen: Kevin Pietersen ($650,000), Cameron White ($1.1m), JP Duminy ($300,000), Shikhar Dhawan ($300,000), Michael Lumb ($85,000), Chris Lynn ($20,000)
Bowlers: Ishant Sharma ($450,000), Dale Steyn ($1.2m), Pragyan Ojha ($500,000), Amit Mishra ($300,000), Manpreet Gony ($290,000), Rusty Theron ($85,000)
Allrounders: Dan Christian ($900,000)
Wicketkeepers: Kumar Sangakkara ($700,000)

Royal Challengers Bangalore in IPL 4

Royal Challengers Bangalore

No. of players bought: 16 (6 Indian, 10 foreign)
Money spent: $8.64m
Big-ticket signing: Saurabh Tiwary ($1.6m)
Bargain buy: Daniel Vettori ($550,000)
Eyebrow-raiser: Saurabh Tiwary - Another beneficiary of the frenzy for Indian batting talent. Shone in IPL 2010, but isn't exactly a big-name star, or a local player who will pull the crowds in.
One that got away: Gambhir (bid $1.8m), Kallis (bid $1m), Ross Taylor (bid $0.95m)

This was another franchise which bet big on young Indian batting talent, and it reflected in their decision to retain Kohli and to aggressively pursue Saurabh Tiwary and Cheteshwar Pujara. In each of the first three seasons, Delhi's formidable squad made them pre-tournament favourites. Bangalore have now poached most of Delhi's erstwhile overseas talent - explosive and experienced top-order batting pair of Tillakaratne Dilshan and AB de Villiers, fast bowler Dirk Nannes and allrounder Daniel Vettori. It is a strong squad but the worries are the shortage of multi-skilled players and spinners. The owners would have also liked more local flavour in the outfit: the only Karnataka player they have currently is Abhimanyu Mithun. Expect them to go all out to secure Manish Pandey's services.

Squad
Batsmen: Virat Kohli (retained), Saurabh Tiwary ($1.6m), Cheteshwar Pujara ($700,000), Tillakaratne Dilshan ($650,000), Mohammad Kaif ($130,000), Luke Pomersbach ($50,000), Rilee Rossouw ($20,000), Jonathan Vandiar ($20,000)
Bowlers: Zaheer Khan ($900,000), Dirk Nannes ($650,000), Abhimanyu Mithun ($260,000), Charl Langeveldt ($140,000), Nuwan Pradeep ($20,000)
Allrounders: Daniel Vettori ($550,000), Johan van der Wath ($50,000)
Wicketkeepers: AB de Villiers ($1.1m
