What are the different types of cheques
Cheque-Cheque is an important document that an individual, companies, governments and many others use to transact their business. By definition, cheque can be termed as a negotiable document to transfer money either in physical form or to effect inter account transfer
Unless or otherwise stated, a cheque is a signed unconditional order addressing the bank to credit it by the issuer. The issuer of the cheque will have an account with the bank to which it is connected. The account can be either savings type or a current account. A cheque transaction is one of the safest ways of conducting the business because it leaves an entry against the cheque honoured by the bank in the banking transactions conducted by you which can be traced back in case of necessity. There are various types of cheques and various ways of issuing a cheque
Different types of cheques based on methods of issuing -
1-Open cheque or bearer cheque: The issuer of the cheque would just fill the name of the person to whom the cheque is issued, writes the amount and attaches his signature and nothing else. This type of issuing a cheque is also called bearer type cheque also known as open cheque or uncrossed cheque. The cheque is negotiable from the date of issue to three months. The issued cheque turns stale after the completion of three months. It has to be revalidated before presenting to the bank.
2-A crossed cheque or an account payee cheque: It is written in the same as that of bearer cheque but issuer specifically specifies it as account payee on the left hand top corner or simply crosses it twice with two parallel lines on the right hand top corner. The bearer of the cheque presenting it to the bank should have an account in the branch to which the written sum is deposited. It is safest type of cheques.
3-A self cheque: A self cheque is written by the account holder as pay self to receive the money in the physical form from the branch where he holds his account.
4-Pay yourself cheque: The account holder issues this type of crossed cheque to the bank asking the bank deduct money from his account into bank’s own account for the purpose buying banking products like drafts, pay orders, fixed deposit receipts or for depositing money into other accounts held by him like recurring deposits and loan accounts.
5-Post dated cheque (PDC): A PDC is a form of a crossed or account payee bearer cheque but post dated to meet the said financial obligation at a future date.
Various types of cheques based on their functionality:-
1-Local Cheque: A local cheque is a type of cheque which is valid in the given city and a given branch in which the issuer has an account and to which it is connected. The producer of the cheque in whose name it is issued can directly go to the designated bank and receive the money in the physical form. If a given city’s local cheque is presented elsewhere shall attract some fixed banking charges. Although these type of cheques are still prevalent, especially with nationalised banks, it is slowly slated to be removed with at par cheque type.
2-At par cheque: With the computerisation and networking of bank branches with its headquarters, a variation to the local cheque has become common place in the name of at par cheque. At par cheque is a cheque which is accepted at par at all its branches across the country. Unlike local cheque it can be present across the country without attracting additional banking charges.
3-Banker’s cheque: It is a kind of cheque issued by the bank itself connected to its own funds. It is a kind of assurance given by the issuer to the client to alley your fears. The personal account connected cheques may bounce for want of funds in his account. To avoid such hurdles, sometimes, the receiver seeks banker’s cheque.
4-Travelers’ cheques: They are a kind of an open type bearer cheque issued by the bank which can be used by the user for withdrawal of money while touring. It is equivalent to carrying cash but in a safe form without fear of losing it.
5-Gift cheque: This is another banking instrument introduced for gifting money to the loved ones instead of hard cash.

Want To Know The Types Of Computer Memory
There are many types of computer memory. If you want to upgrade your computer memory, you have to know the different types of memory. Computer memory is an internal storage area that stores data permanently or temporarily. It also affects the speed by which the computer processes the data. Today’s computer has a combination of memory, and not just one type.
Computer memory has four basic types. These are Cache, RAM, Virtual and Hard Drive.
The Hard Drive memory is where you permanently store your data. It contains program files, permanent files, Internet files and files that are saved by the user. The capacity of the Hard Drive memory is measured by gigabytes. The Hard Drive memory capacity of old computers or laptops starts from 20 gigabytes. Today, most computers come with 360 gigabytes or higher.
The Virtual memory plays its role when running applications that are too large to handle by Random Access Memory or RAM. To temporarily store data, the computer’s Operating System uses the Hard Drive and gives it back when needed. Virtual memory’s usage of Hard Drive slows down the performance of the computer.
Cache memory stores the most frequently used processes of the computer. It has 3 grades to indicate its level. Level 1 and 2 are the most common Cache used in most computers and laptop. Level 3 Cache indicates advanced level of systems.
Level 1 Cache memory is used for most frequently used information and processes. It is the primary memory used by the processor. L2 is next in line. It is more commonly used on the motherboard. Depending on the motherboard used in the computer, the L2 can be upgraded or not. L3 is the most advanced Cache memory as it can speed up the memory.
The RAM or Random Access Memory is the most commonly used memory as every file or application that is processed in your memory needs it. Each time a data or application is requested on your computer, the processor sends the request to your RAM, which then processes and writes it back to RAM. But the data that come and go in RAM are temporarily stored. As soon as the application or program is closed, the files are deleted from RAM.
RAM has many types. These are the SDRAM, DDR, SIMM, DIMM, SODIMM, and DRAM.
The SDRAM or Synchronous DRAM retains memory and synchronizes with the timing of the computer. It does not need to refresh. It is faster and more expensive than DRAM. SDRAM’s speeds are 66, 100, 133 and 266 MHZ.
DRAM or Dynamic Random Access Memory holds information for a short time and needs to be refreshed every now and then. It is measured by access time and storage capability.
SIMM is Single In-line Memory modules used to store one row of EDO or BEDO or DRAM chips. SODIMM is Small Outline Dual In-line memory module found in notebooks. It is smaller than standard DIMMs. DIMM or Dual In-line memory module contains 2 rows of DRAM, EDO or BEDO chips. DDR or Double Data Rate doubles the speed rate of data transfer.
Before you purchase the computer memory, you have to know the types of computer memory fit for your computer. Memory used in laptops and notebooks are different from memory used in desktop computer.
