Computer Concepts b> Essentially, a computer is a programmable machine. It allows information, or data, to be stored quickly and easily. Computers and peripherals, such as printers, can be networked together so information can be shared and exchanged between them.
Types of Computer b> Computers are typically classified by their and processing power, although there is considerable overlap between the different types. Laptop or notebook computers are lightweight and portable, whereas desktop computers tend to be larger, more permanent fixtures. Servers, mainframes or workstations are larger computers typically used in commercial settings. Hardware b> Computer hardware is the term used to describe the mechanical, magnetic and electronic components of a computer system. The central processing unit (CPU) is the "brains" of a computer; it interprets the instructions sent to programs. Other hardware components include keyboard, screen and disk drives. Software b> Computer software is the term used to describe the programs that run on, and direct the operation of, a computer system. Software is written in a programming language by a programmer and typical applications include word processing, spreadsheets and databases.
GRAND TOTAL / RATE SETTING MODE SELECTOR: "GT": Grand Total "•": Neutral "RATE SET": To set the date, time, and tax rate, set this switch at the "RATE SET" position. Date: • Enter in the order of month, day and year, then press to complete the entry. • Use to separate month, day, and year. • When is pressed, the number entered is evaluated and displayed as "date" if the value is within the following range; "Error" is displayed otherwise, and the previously set date is restored. Month: 1 - 12; day: 1 - 31; Year: 2000 - 2099 (in 4 digits) or 00 - 99 (in 2 digits) Time: • Enter in the order of hour, minutes, then press to complete the entry. (There is no entry available for the seconds value. The clock starts at zero second.) • If the hour/minute digit is less than 10, it is not necessary to enter the first digit "0". • Use to separate hour and minute values. • When is pressed, the number entered is evaluated and displayed as "time" if the value is within the following range; "Error" is displayed otherwise, and the previously set time is restored. Hour: 0 - 23 (24-hour system for the hour entry), Minute: 0 - 59
The DSUM function is very useful, but it does use a lot of processing. Every DSUM function does a scan of every row of your table. There are a few ways you can reduce computing time.
First (and the most obvious) is to reduce the number of DSUM functions or reduce the size of your table. I presume you have already tried this.
Secondly consider using Pivot Tables to do the task, or to reduce the size of your table. There is a Pivot Table wizard under the Data menu. It's a fairly user friendly feature of Excel, so I suggest you try it out on your table. Pivot tables will be many times faster than DSUM functions because they only scan the table once. There are some tutorials available on the internet.
Third, if your DSUM functions are only summing one value in the table, then it would be much quicker if you can sort the table on the lookup value (or criteria). Then use LOOKUP, VLOOKUP or MATCH functions to find the value you're looking for. On a sorted table, these functions are many times faster that DSUM functions.
I hope this helps a little. It's hard to diagnose without seeing the spreadsheet and knowing the details of the problem you are trying to solve.
